AI video enhancement for footage you want to use again

Combine AI enhancement with high-resolution output to prepare new versions of low-resolution footage, generated clips and existing edits, with more options for editing, publishing and presentation.

Prepare low-resolution clips for a new viewing size

Enhance short clips with low resolution, mild blur or detail lost to compression, preparing footage for another edit or everyday sharing. Use it with AI-generated clips, phone videos and existing short videos.

Four output options, with actual dimensions

Choose 720p, 1080p, 2K or 4K, defined by a short edge of 720, 1080, 1440 or 2160 pixels. Keep the original aspect ratio and prepare a suitable size for landscape displays or portrait publishing, with expected dimensions shown before starting.

Continue with the same footage after watermark removal

Select a video from a watermark-removal success card or an available past result on this site, then continue to upscaling. Connect watermark removal with output preparation so the same footage can move through your creative workflow.

Keep the original timing and clip audio

Keep the original frame rate and the processed segment’s default audio track within the supported range, retaining the timing and sound of the source. Output at the original aspect ratio for subsequent editing and presentation.

How to upscale a video online

Select your footage and output, check the segment and credits, then start. There is no duration setting to configure.

  1. 1

    Select a video

    Upload from your computer, transfer from your phone or select a watermark-removal result from this site. After validation, source information appears. Clips up to 20 seconds are processed in full; longer clips use only the first 20 seconds.

  2. 2

    Choose an output and confirm the credits

    Check the expected dimensions, actual segment and credit quote. Changing the video or output requests a new quote. Confirm and start, then follow task creation, queueing, processing and result saving.

  3. 3

    Preview, then download

    Play the finished result in its card, open a larger preview and download it. Check important frames and audio sync before editing or publishing. Viewing and downloading the result do not incur another credit charge.

Footage worth trying with video enhancement

Prepare a suitable picture size and output for everyday content, brand presentations, product lessons and older footage you want to use again.

AI-generated videos and social clips

Prepare outputs such as 1080p from lower-resolution AI clips, channel updates and portrait videos. Adapt existing content for another edit, platform layout or social media post.

Brand assets and marketing segments

Create another version of event footage, promotional clips or your own footage after watermark removal. Choose an output for the intended placement or display and reuse existing assets in brand content.

Product demos and lesson segments

Prepare high-resolution output from product close-ups, short screen recordings and teaching demonstrations. Bring existing explanation clips into product introductions, course materials and project presentations.

Older videos and archive reuse

Create another viewing copy of older low-resolution footage, family videos or project archives. Use existing clips in retrospective edits, republishing and archive presentations.

AI Video Upscaler FAQ

Check output dimensions, input limits, segment handling and credit rules before starting.

How is AI video upscaling different from ordinary resizing?

AI video upscaling analyzes edges, textures and information across frames to improve the appearance of enlarged footage before resizing it to the selected dimensions. Conventional resizing uses interpolation to change frame dimensions. AI enhancement can also introduce inaccurate detail, so inspect the result.

Does 4K output restore native 4K detail?

No. 4K describes output dimensions, not the quality of the original recording. The tool cannot guarantee recovery of missing or lost information and does not promise lossless enhancement. Severe blur, compression or occlusion may limit improvement.

What do 720p, 1080p, 2K and 4K mean here?

They specify a short edge of 720, 1080, 1440 or 2160 pixels, with the original aspect ratio and even output dimensions. For example, 16:9 4K is 3840×2160; 9:16 is 2160×3840. Output is limited to 8,294,400 pixels and a 3840-pixel long edge. Very wide footage may not support higher options.

How much footage is processed? Can I select a middle segment?

Processing starts at the beginning. Clips up to 20 seconds are processed in full; longer clips use only the first 20 seconds. There is no duration selection, timeline editing, middle-segment selection or 30-second output. The source must still be no longer than 60 seconds.

Which formats and file sizes are supported?

MP4, MOV, WebM and M4V are supported, up to 100MiB (104,857,600 bytes) and 60 seconds in total. After rotation, the source must have at most 2,073,600 pixels and a long edge no greater than 1920 pixels. The frame rate must be constant, no greater than 30FPS and accurately detected by the system. GIF, variable frame rate and larger inputs are not supported. File validation determines eligibility.

Can I upscale portrait video? Will it crop or stretch?

Eligible landscape and portrait videos are supported, with expected dimensions reflecting rotation. The original aspect ratio is retained, without automatic cropping or stretching. Outputs exceeding pixel or long-edge limits are unavailable. An output smaller than the source is also identified.

Are audio and frame rate preserved? Can I convert to 60FPS?

The original supported constant frame rate is retained. Frame interpolation and 60FPS conversion are not provided. The processed segment keeps only its default audio track, or its first track if none is marked default. Other tracks are not retained. Silent footage remains silent; unreadable audio metadata produces a validation error.

Can I continue directly from a watermark-removal result?

Yes. Select a video you can access from a success card or an available past result. The input must still pass format, size and duration checks; some past results may be outside the supported range. If a source has expired or been cleared, upload your saved copy. Selecting it does not start processing automatically.

Is video upscaling free? How are credits calculated?

Processing requires sign-in and credits. Both granted and purchased credits can be used. The quote depends on the actual segment, source pixel count and output option. It appears before starting and is refreshed when settings change, without additional charges in the background. For inputs up to 720p and 30FPS, each five seconds costs 2, 3, 4 or 6 credits for 720p, 1080p, 2K or 4K respectively. The confirmed quote is authoritative.

Why can the same output resolution have a different price?

A larger source still requires processing more input pixels. For example, a ten-second 720p source costs 6 credits for 1080p output; a ten-second 1080p source costs 14. Frame rates below 30FPS do not receive a discount. Short clips are quoted for their actual processed duration, with the final credit amount rounded up.

Are failed tasks refunded? Can repeated clicks charge twice?

A failed task receives one refund of its original debit, retaining the original credit expiry. Already expired credits may therefore remain unusable. One submission corresponds to one task and one debit. After a network interruption or uncertain submission, the original task is checked rather than automatically creating another. Voluntarily processing again after success is a new task with a new confirmed charge.

How long does processing take? Are the examples my result?

Processing time depends on the source video, output option and queue. Page examples illustrate upscaling results and are unrelated to your uploaded file. The result area shows your corresponding output only after your task finishes.

Should I choose 1080p or 4K?

Choose for your intended use. Consider 1080p for everyday clips and 2K or 4K when a larger display size is needed. Higher options increase dimensions and credits but do not guarantee more real detail. For severe blur or unreadable captions, look for a better source file first.

About these capabilities

AI super-resolution is followed by resizing to the chosen output. Output options do not mean native AI 4× upscaling. Frame interpolation, dedicated denoising, relighting and watermark removal are not included. Use the corresponding tool first when watermark removal is needed.
