When a video is cropped, zoomed in, or reframed, the existing pixels need to cover a larger area. This can make the result look softer or blurrier, especially when using Auto Reframe to convert a video to a different aspect ratio.
AI Enhance uses AI super-resolution to rebuild visual details and improve the clarity of your exported video.
It can be especially useful when:
Auto Reframe or cropping has zoomed in on your original footage
Your source video has a relatively low resolution
Your footage has been compressed
You want a sharper 1080p, 2K, or 4K result
AI Enhance vs. export resolution
Choosing a higher export resolution and using AI Enhance are not the same thing.
For example, exporting a 720p video at 4K increases the number of pixels in the exported file, but it does not create additional detail from the original footage. Existing pixels are essentially resized to fit the larger output.
AI Enhance goes a step further. It analyzes the image and reconstructs details such as edges, textures, faces, hair, and text to create a sharper result.
| Higher export resolution | AI Enhance |
What it does | Resizes the video to a larger output | Uses AI to reconstruct visual details |
Improves actual detail | No | Yes |
Supports up to 4K output | Yes | Yes |
Uses credits | No | Yes |
Think of resolution as the size of a photo, while AI Enhance affects the detail inside the photo. Making a small photo larger does not automatically make it sharper.
How to use AI Enhance in the Editor
Finish editing your video.
Click Save & Export.
Select an export resolution of 1080p, 2K, or 4K.
Turn on AI Enhance.
Review the estimated credit cost.
Click Save & Export to start processing
AI Enhance is available for exports at 1080p or higher.
Your original media and timeline are not modified. AI Enhance is applied only to the exported result.
If you return to the Editor later, you will still see your original footage. AI Enhance also will not automatically carry over when you edit, trim, or change the resolution of the video again.
How to enhance a video from the Clip page
You can also enhance an individual clip after it has been created.
Find the clip you want to enhance.
Open the video options or click AI Enhance.
Review the target resolution and credit cost.
Confirm to start processing.
Once processing is complete, the enhanced version will replace the previous exported version for preview and download.
If the current clip was exported at 720p or below, AI Enhance will process it at a minimum output resolution of 1080p.
While enhancement is processing, some actions — including downloading, publishing, trimming, and opening the clip in the Editor — may be temporarily unavailable.
How credits are calculated
AI Enhance is available to paid subscribers and uses credits in addition to your subscription.
Credits are calculated based on the duration of the video and the output resolution:
Output resolution | Credit usage |
1080p | 1 credit per second |
2K | 1.5 credits per second |
4K | 2 credits per second |
For example, enhancing a 60-second video costs approximately:
60 credits at 1080p
90 credits at 2K
120 credits at 4K
Each clip requires at least 1 credit.
You will see the estimated credit cost before processing begins. Credits are deducted when you submit the export or enhancement.
If you do not have enough credits, you will be prompted to add more credits before continuing.
If AI Enhance fails to process successfully, the credits used for that attempt will be refunded.
Can I export a low-resolution video in 4K?
Yes. Vizard allows you to select output resolutions up to 4K, even when your original footage has a lower resolution.
However, selecting 4K by itself does not necessarily make a low-resolution source look sharper.
If your goal is to improve visual clarity rather than simply produce a file with a higher output resolution, turn on AI Enhance.
What results should I expect?
AI Enhance can significantly improve many videos, but the result depends on the quality of the source footage.
It generally works best with:
Clean footage with relatively low resolution
Videos that have become softer because of cropping or reframing
Faces, text, and clearly defined objects
Static or moderately moving scenes
Results may be more limited when the source contains:
Strong compression artifacts or heavy noise
Severe motion blur
Out-of-focus footage
Very fast movement or camera shake
Extremely low-resolution footage being enlarged significantly, such as 240p to 4K
AI reconstructs missing details based on what it sees in the source. If important visual information is already missing, it cannot always reproduce it perfectly.
For longer videos or footage with challenging quality, consider testing AI Enhance on a shorter clip first.
Processing time
AI Enhance requires additional AI processing and normally takes longer than a standard video export.
Higher resolutions and longer videos require more processing time. You can check the estimated processing time on the processing page while your video is being enhanced.
You can leave the page and return later without restarting the enhancement.
Good to know
AI Enhance works with clips and original videos.
Original videos can be submitted for AI Enhance from the Editor.
AI Enhance processes the final exported video rather than changing your original media.
The enhanced output can include your Custom Scenes, intros, and outros.
AI Enhance is not available if your Editor project contains only Custom Scenes.
AI Enhance must be selected each time you want to use it; the setting is not automatically remembered.
The same unedited output cannot be repeatedly enhanced at the same resolution.
Exported files larger than 500 MB may fail to process.
Frequently asked questions
Why does my video still look blurry after I select 4K?
A higher export resolution increases the output dimensions, but it does not automatically add new visual information.
If the source is low resolution or has been enlarged through cropping or Auto Reframe, use AI Enhance to reconstruct additional detail.
If your source video already looked sharp but the exported version unexpectedly looks worse, AI Enhance may not be the right solution. Check the source file quality and playback quality first.
My original video is already 4K. Do I need AI Enhance?
Not necessarily.
If your original footage is already sharp 4K footage and you only need a 4K output, selecting 4K export is usually enough.
AI Enhance is most useful when cropping, reframing, compression, or lower-quality source footage has reduced visible detail.
Can I enhance a 720p video to 4K?
Yes.
However, the larger the difference between the source quality and the target resolution, the more information AI needs to reconstruct. Results can therefore vary.
For very low-resolution footage, we recommend testing a short clip before processing a long video.
Why does 4K AI Enhance cost more than 1080p?
Higher-resolution videos require substantially more AI processing.
4K contains four times as many pixels as 1080p, so enhancing a 4K output requires more computation and therefore uses more credits.
Does AI Enhance change my edit, captions, or video length?
No.
AI Enhance improves the visual frames of the final exported video. It does not change your edits, captions, timing, or video duration.
Is AI Enhance available on the Free plan?
No. AI Enhance is currently available to paid subscribers.
Because AI Enhance requires additional AI processing, it also consumes credits based on the duration and target resolution of the video.
What happens if AI Enhance fails?
The video will show an Enhance failed or Export failed status.
Credits charged for the failed enhancement will be refunded, and you can try submitting the video again.
