How do I remove a green screen?
Choose your video or try the sample, then check the Result preview. Select Green or Blue, use Auto-detect, or pick the exact screen color from a paused frame. Adjust Removal strength until the backdrop disappears, then refine Edge softness and Spill removal. Play through the footage before exporting.
Can I replace the screen with my own picture?
Yes. Choose Image and add a JPG, PNG or WebP up to 20 MB and 24 megapixels, with neither edge over 8192 pixels. Fill frame covers the scene and crops image edges; Fit entire image preserves the whole picture and uses Padding color for the remaining space. Color and two-color gradient backgrounds are also available, with optional gradient animation.
Can I download a transparent video?
Video exports include the selected background; MP4 and WebM exports here do not preserve transparency. For a transparent still, seek to a frame, keep Transparent PNG checked, then prepare and download the PNG frame. Cutout preview uses a checkerboard to show transparent areas; the checkerboard is not part of the PNG.
What does the Matte preview show?
The matte is a guide to the cutout: white pixels stay, black pixels are removed, and gray pixels are partly transparent. If you see black holes in your subject, reduce Removal strength or choose a more accurate screen color. Increase softness gently to avoid making the outline hazy.
Does this remove any video background with AI?
No. This is a chroma-key tool for footage filmed against a reasonably consistent color, usually green or blue. Matching clothing and objects can disappear too. Hair, motion blur, compression, strong shadows and reflected screen color may need careful adjustment; perfect separation is not guaranteed. It is not an automatic person-segmentation tool for ordinary rooms.
Which files work, and is sound kept?
Input supports MP4, MOV, M4V, WebM and MKV with browser-supported codecs, up to 500 MB, 20 minutes and 4K pixels. Use updated desktop Chrome or Edge as a starting point. One video track and at most one audio track are supported. Keep sound is on by default. Compatible AAC or Opus audio is copied; other supported audio is converted as needed. Export stops if the selected tracks cannot be retained.
Will the quality or original file change?
Your original file stays unchanged. The export is a newly encoded video at original size up to UHD 4K (3840 by 2160) or DCI 4K (4096 by 2160), including portrait equivalents, or a smaller 1080p, 720p or 480p size, without upscaling. 4K export needs a compatible encoder and takes more time and memory. Output is limited to 256 MB. Some detail can be lost and file size can increase; preview the export before sharing. Embedded subtitles, descriptive metadata and specialist HDR/color workflows are not preserved or guaranteed. There is no account, watermark or paid tier for this tool.
