Questions
Good to know
How long does it take?
Processing time depends on the clip length, source resolution, frame rate, selected mode, and device. Test a short section on your own device before starting a long export. The app shows an estimate before you start; no universal processing-time benchmark is claimed.
Can I use my phone while it works?
Yes. Keep using other apps or lock your phone. Upscaling continues in the background with progress shown by iOS, and you'll get a notification when it's done.
Does it keep the sound?
Yes. The original audio is copied into the new video exactly as it was, so it stays in sync.
Are my videos uploaded?
No. Local Video Upscaler runs its AI model on your iPhone, iPad, or Mac. Videos are never uploaded, and there's no account.
What about HDR videos?
HDR videos are saved in standard dynamic range.
Is my original changed?
No. The app always saves a new copy.
How much does it cost?
$9.99 once in the U.S. App Store, checked November 10, 2026. No subscription or in-app purchases. Apple shows your local price before purchase.
What can it improve?
Soft, low-resolution footage and compression artifacts. It cannot recover heavy motion blur or out-of-focus detail. Output is capped at 4K; videos already at 4K are skipped. HDR exports use standard dynamic range. Your original is never changed.
Which devices are supported?
Available for iPhone with iOS 26.0 or later, iPad with iPadOS 26.0 or later, and Mac with macOS 26.0 or later. Universal purchase includes the approved iPhone, iPad, and Mac versions with one purchase.

Common checks
It's taking a while.
Processing time varies with your device, clip length, resolution, frame rate, and selected mode. Start with a short clip and use the app’s estimate to plan longer exports.
It stopped in the background.
iOS can pause background work when your battery is low or another app needs the resources. Open the app and tap Retry.
Your iPhone feels warm.
That's normal during long jobs. iOS slows processing down on its own if your phone gets hot, and the app lets you know.
Can't save to Photos.
Allow Local Video Upscaler to add to your Photos library in Settings, then try again. Your upscaled videos are also in the Files app, under On My iPhone › Local Video Upscaler › Upscaled.
Faces look too smooth.
Choose the Natural look. Clean is meant for very grainy or blocky footage.

## Improve Old Videos on iPhone: Real Demo & Offline Steps

Improve old videos on iPhone, without uploads
Updated November 3, 2026 · A practical guide from Local Video Upscaler
You can enlarge a low-resolution video on iPhone without uploading it.
Local Video Upscaler by David Balderston processes clips on device and costs $9.99 once in the US App Store, with no subscription or in-app purchases. It requires iOS/iPadOS 26 or later. It can improve some soft, compressed footage; it cannot faithfully recover a badly missed focus or heavy motion blur.
First check the source. If the recording is already 4K, this app skips it. If your phone cannot run iOS 26, check another tool’s requirements before buying.
Apple shows the current price and compatibility.
Old phone clips and camcorder transfers can look soft on a modern screen. Upscaling can make some low-resolution footage easier to watch, but it cannot reliably recreate detail that was never captured. Start with the best file you can find, then judge a preview before processing the whole video.
What is wrong with the clip?
On a small screen, scroll the comparison table sideways to read the problem, next step, and limits together.
Choose the next step from the source problem
What you see
First thing to try
Limit to expect
Small frames that look soft when enlarged
Use the original file, then compare 2× and 4× on the same frame.
More pixels do not guarantee recovered detail.
Blocky video from a message or download
Look for an original Photos or camera file before processing. Compare Natural and Clean.
Compression may already have discarded information.
A moving person smears across frames
Compare a short processed section in motion, not just a paused frame.
Upscaling cannot reliably undo heavy motion blur.
The whole subject was out of focus
Check whether another recording or sharper original exists.
AI may invent plausible edges rather than restore the real subject.
Video shakes, skips, or has the wrong color
Identify stabilization, playback or HDR needs separately.
This is not a stabilizer or frame-interpolation editor; HDR exports become SDR.
Find the best original first
If someone sent the clip through a messaging app, ask for the original file or look for it in the original device, backup, or camera transfer. A compressed message export may have lost detail before you begin. Increasing its dimensions does not undo every compression artifact.
Keep a backup of that original. Try a short clip first, especially if it is badly blurred or heavily compressed.
Upscale a copy in Local Video Upscaler
The app processes on your device and works offline without uploading your video. Other tools can also offer offline processing; this guide describes this app’s workflow.
Choose a video from Photos or Files.
Import the best available copy rather than a screenshot or screen recording of the video.
Compare 2× and 4×.
These choices increase the frame dimensions, subject to the app’s output limit of up to 4K. A 4× choice does not mean every input becomes 4K or gains four times as much real detail.
Choose Natural or Clean.
Natural keeps more texture; Clean smooths heavier grain and compression blocks. Compare skin, hair, text, and edges in the preview. If faces look too smooth, try Natural.
Inspect the preview frame.
Drag across the before-and-after view and use the zoom control to check detail. A good-looking frame does not prove that every frame or moving subject will look good.
Process, then review the complete video.
Watch movement as well as still details before deciding whether to keep the result.
Save a new copy.
Use Save to Photos or share the output. You can also find upscaled videos in Files, under On My iPhone → Local Video Upscaler → Upscaled. The source video is not overwritten.

This prepared film excerpt is not a customer’s home movie. Watch for changing texture and edges during movement; do not infer that a paused frame represents every frame. The downloadable MP4 is the comparison presentation, not the raw processed export.
Using a Mac? See export checks in QuickTime Player and Finder.
A disclosed still-frame example
Before:
640×360, JPEG-compressed sample.
After:
Natural model at 4×, resized to 1920×1080 for display.
This is an AI-generated fictional still, not a customer’s family video. The original sample was reduced to 640×360 and JPEG quality 55, processed with the same Natural model weights used by the app, then resized for this display. It demonstrates a still-frame model result, not a full video export, motion consistency, or an iPhone speed benchmark. Results vary with the input.
Know the limits before starting
Blur:
soft low-resolution footage may improve, but heavy motion blur and out-of-focus shots cannot be reliably recovered. Inspect the result for invented-looking details.
HDR:
HDR input is saved in standard dynamic range. Keep the original if preserving its HDR appearance matters.
Time:
upscaling is computationally heavy. Test a short clip on your own device and use the app’s estimate; device, settings, frame count and temperature affect processing. This demo provides no iPhone timing benchmark.
Size:
output is capped at 4K; already-4K videos are skipped. A larger file is not automatically a better-looking video.

Check the saved video before sharing
Play the whole test.
Watch fast movement and faces at the same display size as the original. Stop if you prefer the source.
Check orientation and dimensions.
A portrait clip should stay portrait. A 4× choice is capped at 4K; it does not turn every input into 3840 × 2160.
Listen at the beginning and end.
Check that speech and sound remain in sync. Keep a separate copy of any irreplaceable recording.
Check color.
HDR inputs export as standard dynamic range. Compare skin tones and bright highlights in the player you will use.
Open the destination copy.
Check the file saved to Photos or Files, rather than relying on a preview inside the app.
The app exports HEVC video. If a destination cannot play it, keep the original and use a compatible player or a separate converter; upscaling itself is not a universal compatibility fix.

Practical guide
Video upscaling tools: Local Video Upscaler, Topaz, and Video2X
By
David Balderston
· Updated
October 24, 2026
For a short, low-resolution personal clip on a compatible Apple device,
Local Video Upscaler is a $9.99 one-time purchase that processes video on device
. For a desktop restoration workflow with more models and temporal tools, consider Topaz Video. For a free, open-source workflow on a suitable computer, consider Video2X.
Written by David Balderston, Local Video Upscaler’s developer. This compares documented capabilities and setup requirements, not independently measured output quality or processing speed. Capabilities were checked on October 10, 2026. Local Video Upscaler purchase terms were rechecked on November 10, 2026 and the displayed Topaz annual price on October 24, 2026; these are different billing views, not equivalent offers.

Mac availability:
Available for iPhone with iOS 26.0 or later, iPad with iPadOS 26.0 or later, and Mac with macOS 26.0 or later. Universal purchase includes the approved iPhone, iPad, and Mac versions with one purchase. Runtime performance and output equivalence across platforms have not been independently verified.
Choose Local Video Upscaler for a focused Apple-device workflow
Select a clip, choose Natural or Clean, select 2× or 4×, and save an enlarged copy. Output is capped at 4K and uses HEVC, with the source frame rate and synchronized audio retained. The original is preserved. Natural and Clean offer different processing choices; inspect the same short section before committing to a long job.
It is aimed at low-resolution source clips. Inputs already at 4K are skipped. HDR input is exported as SDR, so it is not the right choice when preserving an HDR delivery workflow is essential. Heavy motion blur, out-of-focus footage, and missing detail can remain poor. It does not provide frame interpolation, stabilization, a video editor, or a cloud render queue. Read the
full product facts
and
2× versus 4× guide
.
Choose Topaz when you need desktop restoration controls
Topaz Video advertises several jobs beyond enlargement: denoising, frame interpolation, stabilization, and model choices. Those controls matter when the problem is more than a small frame size. A desktop workflow also allows you to choose a computer and GPU for the job.
Check the current hardware requirements, plan terms, and export controls against your actual source. Local rendering and cloud credits are different options. This comparison does not establish that every model will work well on every kind of archive footage.
Choose Video2X when you want an open-source setup
Video2X is a Vulkan-based video-processing project with upscaling and frame-interpolation support. It is a computer workflow with installation, model, driver, and GPU considerations. Its repository is the right place to check supported packages and current instructions; it is not an iPhone app.
Free software can still cost time to configure and computer time to process. It may fit a technical user who wants control and is comfortable testing settings. It is less convenient when the goal is simply to improve a clip already in an iPhone photo library.
A fair test starts with the same source
Retain the highest-quality original you have. Avoid downloading a compressed social-media copy if an original exists.
Choose a short section with movement, faces, fine texture, and any text that matters.
Use the same output dimensions and frame rate where each tool permits them. Record any difference.
Compare playback as well as paused frames. Look for flicker, halos, waxy faces, and changing detail across adjacent frames.
Check audio synchronization, duration, orientation, and color. HDR-to-SDR conversion is a material difference.
Record the app version, device, settings, input/output dimensions, and elapsed processing time. Do not compare a phone’s timing with a desktop’s without naming the hardware.
The
old-video guide
shows the selection and comparison workflow. Its still-image example is explicitly labeled as a synthetic illustration; it is not a measured video or competitor benchmark.
Does 4K output mean the clip contains real 4K detail?
No. It means the output has those pixel dimensions. Upscaling can make an old clip more pleasing on a larger screen, but it does not recreate a missing camera original or prove that generated detail is historically accurate. For family archives, retain and label both the original and enhanced copy.
Should you use a photo upscaler instead?
A photo enhancer works on individual images. Video also has motion, timing, audio, and consistency across frames. Choose a video workflow for a playable clip, and a
photo enhancer
for an individual photograph or extracted still.

2× or 4× video upscaling? Dimensions, limits, and quality checks
By
David Balderston
· Updated
October 10, 2026
2× doubles each pixel dimension; 4× quadruples each dimension.
That means 2× produces four times as many pixels per frame, while 4× produces sixteen times as many—before an app’s output cap applies. Pick the size your viewing or editing task needs, then inspect the result.
By David Balderston, developer of Local Video Upscaler. Updated October 10, 2026. The examples below are resolution arithmetic, not processing-time measurements or evidence of recovered detail.

Source dimensions
Nominal 2× output
Nominal 4× output
Practical interpretation
640 × 360
1280 × 720
2560 × 1440
2× reaches a 720p frame; 4× reaches a 1440p frame
1280 × 720
2560 × 1440
5120 × 2880
Nominal 4× exceeds a 4K cap; check the actual exported dimensions
1920 × 1080
3840 × 2160
7680 × 4320
2× already reaches a 4K frame; 4× cannot exceed the app’s 4K cap
These are 16:9 examples. Portrait and other aspect ratios have different dimensions. Local Video Upscaler caps output at 4K and skips inputs already at 4K. A scale selection is not a promise that every source exports at exactly that multiple.
Start with the smallest useful enlargement
If you want a 640 × 360 family clip to look more comfortable on a phone or small display, try 2× first. Compare a short section at the same display size. If the destination needs a larger frame, try 4× and inspect whether it improves the viewing experience enough to justify the larger output and processing work.
For a 1920 × 1080 source, nominal 2× already reaches 3840 × 2160. Selecting 4× does not bypass Local Video Upscaler’s output cap. Larger dimensions do not guarantee a sharper face, readable text, or restored motion detail.
Pixel count is different from processing time
For a source with width W and height H, a nominal 2× frame has
(2W) × (2H) = 4WH
pixels. A nominal 4× frame has
16WH
pixels. Processing time also depends on the model, source length, device, temperature, frame rate, and output cap. The arithmetic does not establish a four-times timing difference between settings.
Test a short clip on your actual device before starting a long export. Keep the device supplied with power when practical, allow ventilation, and leave space for the source and output. No universal minutes-per-minute benchmark is claimed here.
Inspect movement, not just one flattering frame
Pause on a face and inspect edges, eyes, teeth, hair, and text. Then play the same section and look for detail that changes unnaturally from frame to frame. Compare the original and output at the same viewing size. An enlarged frame can look smoother because of how it is displayed, without containing more reliable information.
Try Natural and Clean on the same short source if you are choosing between modes. Record your choice and the app version. The best setting for one clip can be a poor fit for another.
Check the export before archiving it
Local Video Upscaler exports HEVC video with the source frame rate and synchronized audio. HDR sources become SDR. Check dimensions, duration, orientation, playback, audio synchronization, and color in the app you intend to use next. Keep the original and mark the enhanced copy so you can distinguish them later.

Mac App Store screenshot of the current Mac version (1.0.1): choose videos, choose from Files, or drop videos onto the window. The headline above the window was added for the App Store listing, and the before-and-after picture inside it is a sample, not a measured result.
This workflow is for an existing digital video file. It does not digitize a tape, stabilize a shaky recording, generate extra frames, or promise to recover detail that was never captured.

Open
the Mac App Store listing
on the Mac you intend to use. A newer app version or a mobile listing does not by itself prove your Mac is supported.
Keep the original file.
Start from a camera transfer, original Photos export or original download, rather than a screen recording of another player.
Check the starting size.
Already-4K videos are skipped. A 360p, 720p or 1080p source leaves room for enlargement, but its detail and compression still set the quality ceiling.
Allow space for a second file.
Keep the input plus the processed copy. Output size depends on the clip, so a fixed storage-per-minute promise would be misleading.
Preview one short, representative clip
Choose a video in the app.
For a long archive, begin with a short copy that includes a face, movement and a textured area. Keep any edits separate from the original.
Compare Natural and Clean.
Natural aims to retain texture. Clean smooths heavier grain and compression. Check skin, hair, text and edges instead of choosing the smoothest-looking frame.
Choose 2× or 4×.
The output is capped at 4K. A 640 × 360 input nominally reaches 1280 × 720 at 2× or 2560 × 1440 at 4×; it does not automatically become 4K.
See the worked resolution examples.
Compare at the same display size.
A larger player window or a different crop is not a fair before-and-after comparison. Look for plausible texture becoming invented detail.
Process a copy, then inspect it outside the preview
Start the short test and review the completed file in your intended player before processing a long clip or queue. Local processing keeps the video on your device; it does not make the work instantaneous. Device, settings, frame count and temperature affect processing time.
Motion
Play movement at normal speed. Check for flickering edges or faces changing between frames. A sharp still frame alone is insufficient.
Size and orientation
Check exported dimensions and portrait/landscape orientation. The 4K cap applies even when the selected enlargement would calculate a larger image.
Sound
The app preserves source audio and frame rate. Listen to speech and check synchronization at both ends of the clip.
Format and color
Output is HEVC. HDR input becomes SDR, so check bright areas and color in the destination player. This workflow does not preserve an HDR master.
Originals
Keep the source and label the enhanced file. AI estimates detail and cannot guarantee a historically faithful reconstruction.
Watch actual output, then check your own Mac export
The existing
before-and-after video demonstration
uses a licensed film excerpt prepared at 360p and processed with Natural 4×. Its disclosed export is 3452 × 1440 with all 192 frames and original audio preserved. This eight-second comparison sample is separate from the earlier four-second, 96-frame source/export pair available on the
results page
. It was produced in desktop Simulator, so it is output-quality evidence for that sample, not a Mac or iPhone speed benchmark.

The same eight-second excerpt before and after, at its original playback speed; the close-up starts after two seconds. A licensed film sample was reduced and compressed to 360p, then upscaled with Natural 4× in desktop Simulator. Actual export: 3452 × 1440, 192 frames, original audio preserved. This is one sample’s output, not a Mac or iPhone processing-speed benchmark. Results vary with your footage.

What this example proves
The 3452 × 1440 dimensions describe the app’s processed sample. The downloadable 1920 × 1080 landscape MP4 is a comparison presentation containing labels and a close-up, not the raw HEVC export. The sample was processed in desktop Simulator; it does not establish native Mac timing or performance on your device. No processing-time or output-file-size benchmark is available here.
Check the saved file on your Mac
Open the completed copy in QuickTime Player and choose
Window → Show Movie Inspector
. Compare its resolution and frame rate with the original; a larger player window does not prove a larger file resolution.
In Finder, select the exported copy and choose
File → Get Info
to check its file size. Keep enough space for the source and output; this example is not a storage-per-minute estimate.
Play faces and moving edges at normal speed. Listen at the beginning and end for audio synchronization. A good preview frame is not a full motion test.
Compare bright highlights and skin tones. The app exports HEVC and converts HDR to SDR; keep your original HDR file if that appearance matters.

When another workflow is a better fit
If you need stabilization, frame interpolation, detailed timeline editing, HDR output or damaged-tape repair, check those requirements in a dedicated tool before paying.
The comparison guide
explains the difference between focused on-device enlargement, desktop restoration controls and open-source workflows.
If you only need still-image enlargement, use
Local Photo Upscaler
. If you need both types of media,
compare Photo, Video and the bundle
. On a Mac, Photo needs Apple silicon and macOS 15.2+, and Video needs macOS 26+.

Generated in Local Video Upscaler 1.0.1 (6), Natural 4×, in desktop iOS Simulator. The source's pixel aspect ratio produces an app display width of 863 pixels; the output is 3452 pixels wide. This is why the coded input width multiplied by four is not the reported output width.
The sample has audio tracks and a four-second video stream. It is SDR; it does not demonstrate HDR preservation. HEVC MOV playback depends on your player. The existing side-by-side website video is an edited comparison presentation; the download above is the actual retained app export.

Historical physical-iPhone measurements
These are a different experiment from the downloadable demo.
The following runs used a physical iPhone 16 Pro, iOS 26.6.2 as recorded, and an ordinary Release test installation with a calibration fix. Each clip contained 92 frames and about 3.1 seconds of video. The receipt is dated October 1 UTC, September 30 Pacific. The final run's thermal state was not recorded.

These short historical examples are not a current-version, long-video or sustained-performance guarantee. They should not be extrapolated into a promised time for a one-minute or one-hour video. Current output settings, device, source and conditions can change the result.
The
historical results JSON
retains the original precision, settings, date and qualifications. The media used for those timing tests is not part of the licensed download pack.
How to compare the result fairly
Keep the original and output. Inspect both at the same displayed size rather than judging a larger image as automatically better.
Watch motion and edges as well as a paused frame. More pixels can include estimated detail, not recovered facts.
Check actual saved dimensions, orientation and playback. Listen to sound in the player you intend to use.
Check color and format needs. HDR sources export as SDR; this example does not establish HDR or every-source audio behavior.

What you are watching
The comparison presentation shows an excerpt from
Tears of Steel
by the Blender Foundation. The prepared source and actual saved export play at the same speed. It demonstrates the look of this particular export; it cannot establish quality, audio behavior or processing speed for every source or device.
The prepared source is 864 × 360 coded pixels (863 × 360 as displayed by the app). The saved export is 3452 × 1440. The comparison uses the previously exported eight-second, 192-frame sample. The source and raw export linked below are a separate, earlier four-second excerpt (96 frames at 24 fps) from the same film. The eleven-second comparison presentation adds labels, a close-up and a closing card; it is not the raw downloadable export.

Before you choose an upscaler
Compare the same instant at equal display size. Watch texture stability, faces and edges. This SDR example does not demonstrate preservation of HDR; the app exports HDR sources as SDR.
