Finish your video in one workspace
Tune detail and motion
Choose a Topaz preset, reduce compression artifacts and set a frame rate. Use automatic settings or refine the parameters yourself.
Review before delivery
Play the original and enhanced video together, inspect the comparison, and download the completed file from your history.
Video upscaling from resolution to motion
Set the size, recover useful texture, and decide how the clip should move. Each control solves a different part of the finishing process.

Dimension example only. The available options in the tool depend on your uploaded file.
Upscale video to 4K online
Choose Original, 2K or 4K when the source supports that output. A landscape 1280 × 720 clip can become 3840 × 2160 at 4K; portrait clips keep their orientation. Available targets stay within 1–4× the original dimensions, so a very small source may not offer 4K. Use the dimension example to compare output sizes.
- 2K uses a 2048-pixel long edge
- 4K uses a 3840-pixel long edge
- Source aspect ratio and orientation are retained
Reduce compression artifacts and recover detail
Downloaded clips and older exports often carry blockiness, noise and halos around edges. Start with automatic enhancement, then switch to manual controls if the result needs adjustment. Compression, noise, halo reduction and detail recovery can be tuned separately. Review moving sections as well as still frames; an attractive single frame is not the whole video.
- Automatic enhancement for a simple starting point
- Manual compression, noise, halo and detail controls
- Playback comparison for judging the whole clip
Choose a frame rate up to 60fps
Resolution and motion are separate choices. Keep the original frame rate or enable interpolation and select 24, 30 or 60fps. Interpolation estimates frames between the originals and can make camera movement easier to watch. Review fast action and fine edges for artifacts. Higher frame rates can also increase the quoted processing cost.
- Keep the source frame rate when it already fits
- Choose 24, 30 or 60fps with interpolation
- Check motion and the updated credit quote
Finish the AI video you want to keep
Create and compare your shots first, then bring the selected clip into the upscaler for finishing. This keeps high-resolution processing focused on footage you actually want to use. The same workflow works for compatible camera footage and screen recordings. Completed results remain in history for review and download.
- Start from an existing MP4 or MOV
- Choose a preset for the source footage
- Compare completed versions in the workspace
Four Topaz presets, one video workflow
Start with Proteus, or compare another preset on a representative clip. Source quality and movement affect the result as much as the preset.
Explore the presets, then choose one for your own file in the workspace.
Proteus
The default preset in the workspace. Start with Auto enhancement, review the clip, and use manual compression, noise, halo and detail recovery controls if it needs further adjustment.
Starlight Precise 2.5
An alternative Topaz enhancement preset for the same upload. Compare how it handles fine detail and motion against your source before using it for a longer clip.
Artemis HQ
Another available enhancement option. Try a representative section and inspect faces, edges and compressed areas at the intended output resolution.
Gaia HQ
An additional Topaz preset to compare on your footage. Keep output resolution and frame rate consistent when judging the difference between presets.
How to upscale a video to 4K
Upload the clip you want to keep and choose a finish that fits its source quality.
01
Upload an MP4 or MOV
Open the upscaler and choose a video no larger than 32 MB and no longer than five minutes. The workspace reads its dimensions, duration and frame rate.
Original · 2K · 4K
24 · 30 · 60 fps
02
Configure output and credits
Choose an available resolution, select a Topaz preset and keep the original frame rate or enable interpolation. Review the output dimensions and credit quote, then start processing.
03
Play, compare and download
Wait for enhancement and saving to finish. Compare the original and result in the video canvas, then download the completed clip from the workspace.
More ways to use your existing footage
Finish a selected take instead of rebuilding the entire project.
Stylized and social clips
Prepare a selected clip for a feed, presentation or larger screen. Start with a good original export and inspect the uploaded version after publishing, because platforms may compress it again.
Campaign and creative clips
Prepare a larger master from a compatible campaign shot or animation. Inspect outlines, textures and motion after enhancement so the result retains the style and important details of the original.
Tutorials and explainer footage
Make visual explanations easier to inspect on larger screens. Enhance compatible clips, then review the result at the intended playback size. Keep text and fine details readable and check moving subjects for artifacts.
AI-generated video
Explore prompts at a practical generation setting, then upscale the take you choose. Check subject consistency and movement across the full result before delivering it or placing it in a longer edit.

AI video upscaler questions
What is an AI video upscaler?
An AI video upscaler increases video resolution using estimated image detail across frames. It can also apply noise reduction and other enhancement settings. Frame interpolation is a separate option that creates intermediate frames to change the motion cadence.
How do I upscale a video to 4K online?
Upload an MP4 or MOV, choose 4K if it is available for your source, select the preset and frame rate, and review the quoted cost. Start processing, then play the comparison and download the completed video. A browser is enough; no desktop editor is required.
Why is 4K unavailable for some videos?
Named outputs must stay within 1–4× the source dimensions and cannot downscale the source. A 1280 × 720 clip can reach 3840 × 2160, while a 640 × 360 clip would need 6× enlargement and cannot use this 4K option. The workspace shows only valid targets.
What are the upload limits?
The video must be MP4 or MOV, no larger than 32 MB and no longer than five minutes. Both limits apply. For a larger file, prepare a shorter clip or a suitable export before uploading, while retaining as much original detail as possible.
Can I convert video to 60fps?
Yes. Enable frame interpolation and choose 60fps, or choose 24 or 30fps. You can also keep the source frame rate within the supported limit. Interpolation estimates new frames, so inspect fast motion and object boundaries before using the result.
Can AI repair a severely blurry video?
It may improve the appearance, but results depend on how much detail remains. Low-resolution and compressed footage is a more useful starting point than heavy motion blur or extreme digital zoom. Upscaling cannot guarantee an accurate reconstruction of missing detail.
Is this a free video upscaler?
Video processing uses credits. The quote depends on duration, output resolution and frame rate and appears before submission. Check your balance and current plans to choose the output that fits your budget.
Can I upscale images in the same tool?
Yes. The workspace accepts images as well as videos, and the controls adapt to the uploaded media. The AI Image Upscaler page covers photo enlargement, sharpening and optional face enhancement.
