Remove Background from MP4 Video Online
MP4 is the most common source format for phone, camera, and social footage. Use it as the input, then choose the output that matches what you need next.
MP4 input
H.264-friendly upload
Transparent WebM option
Custom image option
Three-stage workflow
From source file to usable foreground
Validate the source, isolate the subject, and export the format you actually need.
02
Remove the scene
AI separates the foreground across the clip.
03
Choose the output
Export transparent WebM or composite the subject over a still image.
Input vs. output
The source can stay MP4 even when the transparent result is WebM
Removing an MP4 background does not mean the transparent output must also be MP4. Standard MP4 is excellent for playback compatibility, but transparent web delivery normally uses WebM.

- Social exports
- Screen recordings
- Creator and product clips
Upload quality
Keep enough resolution around the subject
Avoid repeatedly recompressing the source before upload. Strong block artifacts and motion blur make clean mask edges more difficult.
What this page resolves
Match the workflow to the real job
The file extension describes a container, not the exact video codec inside it. Two files with the same extension can decode differently, so the upload is validated before processing and difficult files may need to be re-encoded in a standard editor.
The source container does not determine the transparent delivery format. MP4, MOV, and WebM are accepted as inputs, while a transparent result is delivered as WebM and a result with a replacement image is delivered as a conventional composited video.
Source preparation
Small input changes prevent avoidable edge problems
Use the highest-quality original available instead of a copy downloaded from a social platform. Keep the subject large enough to see, avoid aggressive compression, and prefer even lighting with visual separation between foreground and background.
Preview the beginning, middle, and end before upload. A clip that looks easy in its first frame may contain crossed hands, hair movement, camera cuts, fast rotation, or an object that briefly disappears behind another element.

Verified product limits
Inputs, outputs, credits, and plan limits
The live remover accepts MP4, MOV, and WebM. Transparent mode returns WebM; custom-background mode accepts one JPG, PNG, or WebP image up to 10 MB. A still image is composited behind the isolated foreground—the product does not currently accept a replacement video.
The free trial supports one verified clip up to 5 seconds and 50 MB. Paid plans raise the limit to 60, 180, or 300 seconds and 200 or 500 MB depending on tier. Processing credits are rounded up in five-second blocks, so a 6-second clip uses 10 credits.
- MP4, MOV, or WebM input
- Transparent WebM output
- JPG, PNG, or WebP background
- 5 credits per started 5-second block
Questions
Details worth checking before you export
Do I need to convert MP4 before uploading?+
No. MP4 is a supported input format.
Will the transparent result be MP4?+
Transparent mode exports WebM because the standard MP4 workflow does not preserve alpha.
Can I add a background image instead?+
Yes. Choose custom background mode and upload JPG, PNG, or WebP.
How are video background removal credits calculated?+
Credits follow processed duration and round up to the next five-second block. A clip from 1–5 seconds uses 5 credits, 6–10 seconds uses 10 credits, and the same rule continues for longer clips.
What are the current upload limits?+
The verified free trial allows one clip up to 5 seconds and 50 MB. Depending on the paid tier, limits increase to 60, 180, or 300 seconds and 200 or 500 MB. Background images are limited to 10 MB.
