Fix a pixelated video
No upscales yet
How to fix pixelated video: upload an MP4 or MOV up to 10MB and 30 seconds, then enlarge it 2x or 4x.
Continue the repair
Quick answer
How to fix pixelated video starts with the original MP4 or MOV, not a screen recording of the player. Upload a clip up to 10MB and 30 seconds, enlarge it 2x or 4x, and keep the file only if text and edges look cleaner in motion. This repair builds a larger frame. It cannot restore detail that was never recorded.
Square blocks appear when a small frame is stretched, or when a platform compresses the file again. Fix pixelated video by repairing that source file. Do not screen-record the blocky playback and run the recording through the tool.

Proof
These examples use the same upscaler on a compressed talking-head clip and a gameplay clip. They show enlargement, not a promise that every blocky export becomes sharp.
What changes
Enlarging the frame is different from letting a player stretch the same small pixels. Use this repair when the blocks come from size or compression, not from a shot that was out of focus.
A player makes square blocks obvious when it scales a small export to fill the screen. This repair creates a larger frame at 2x or 4x. Check the edges before you publish.
A larger MP4 you can compare against the original.
The workbench multiplies the uploaded width and height by the factor you pick. A 960 x 540 clip at 4x is calculated as 3840 x 2160. A smaller source may land at 1080p or another exact size.
An estimate of width, height, and credits before processing.
Play the original and the enlarged clip at the same moment. Check faces, captions, UI edges, and high-contrast lines. A larger frame is not a promise that every block disappears.
A side-by-side look at the source and the enlarged clip.
Social downloads and screen recordings add another encode. Upload the editor export when you still have it. A second copy of an already blocky file gives the model less to work with.
One repaired file saved to History, with the original still available.
Workflow
Step 1
Use the editor export or camera file, not a download from a social app. This repair starts with the copy that still has the most original detail.
Step 2
This pixelated-video repair accepts one MP4 or MOV up to 10MB and 30 seconds. Longer or larger files need a shorter cut first.
Step 3
Use 2x when a 720p or 1080p pixelated video is only slightly blocky. Use 4x when the calculated size is the delivery size you need, including 3840 x 2160 from a 960 x 540 source.
Step 4
Play the full clip. Download the enlarged file only if text, faces, and edges look better than the original.
Choose a factor
The right factor is the one whose calculated size matches the slot you need. Use 4x only when that estimate is the size you will publish. A bigger number is not automatically a cleaner picture.
| Situation | Choice | Why |
|---|---|---|
| Mild blocks on a 720p or 1080p export | 2x | Use 2x when a 720p or 1080p pixelated video is only slightly blocky. Cost is 40 credits per second, with a 100-credit minimum. |
| A small export that must fill a 1080p or 4K slot | 4x | Use 4x when the math reaches the size you need. Cost is 70 credits per second, with the same 100-credit minimum. |
| The only file is a social re-download | Repair once, then stop | Another pass on the enlarged file rarely invents detail. Replace it with the original export if you can. |
Scenarios
Limits
This repair stops at a larger frame. It does not restage the shot, rebuild missing text, or remove shake.
This repair cannot recover texture that the export deleted. Heavy zoom, a tiny source, or unreadable text can remain soft after 4x.
The repair accepts MP4 or MOV up to 10MB and 30 seconds. Trim a longer timeline before upload.
Shake, flicker, interlacing, and a wrong frame rate are not fixed by making the frame larger. Denoise or stabilize those problems separately.
2x costs 40 credits per second and 4x costs 70, rounded up, with a 100-credit minimum. The estimate appears before the task starts.
Questions
Enlarge the best MP4 or MOV you already have, then compare 2x and 4x. A new recording is still better when the source is tiny or the text is already unreadable.
You can enlarge it. Depixelate video here by multiplying the frame 2x or 4x. A 960 x 540 source at 4x is calculated as 3840 x 2160. The new pixels are reconstructed, so fine type and textures still need a visual check.
The player is scaling a small or heavily compressed frame up to the display. Exporting closer to the playback size, or running this repair on the original file, avoids that stretch. Zooming a timeline past 100% shows the same blocks and is not a property of the screen.
No. 4x makes a larger frame. Block edges, banding, and crushed text can improve, stay, or look different. Watch the whole clip instead of trusting one paused frame.
