You have a good presenter take with a cluttered office behind it. To reuse it over a screen recording, run the clip through an AI video background remover and export the presenter on a transparent layer. For a standalone social clip, you can use the same footage with a solid background.
Remove the video background in three steps
- In BGChanger, open the video background removal workspace and select Video BG Remover. Upload a short excerpt that includes the hardest part of the take, such as a quick hand gesture or a product held close to the camera.
- Select Transparent if you want a reusable cutout, or choose a solid color if the clip will be shared as-is. The homepage initially selects green, so switch to Transparent before generating an overlay.
- Choose a format that preserves transparency in your receiving app. Generate and download the test, then open it in the editor where you plan to use it before processing the full clip.
If you need footage to practice with, the background removal guide includes a five-second clip and a before-and-after example.
Choose an export your editor can use
An alpha channel tells your editor which parts of each frame are transparent. The format and the receiving app both need to support it. BGChanger offers these options for common workflows.
| What you're making | Format to try |
|---|---|
| Transparent presenter layer for a video editor | MOV ProRes KS if your editor reads ProRes with alpha |
| Transparent web overlay | WebM VP9 if your player or browser supports its alpha channel |
| Standalone clip with a solid background | Standard MP4 with H.264 or H.265 |
If the cutout appears black in a video player, open the original download in your editor and put a bright color layer underneath. If the color shows through, the transparency survived. If the black stays visible, check the original background setting and the import format. BGChanger's standard MP4 export uses a solid background.
Check the cutout over your actual footage
Place the cutout on the track above the screen recording and move it away from the controls you're demonstrating. Play the test against a light part of the recording and then a dark part. A faint halo around hair or a sleeve can disappear against one background and become obvious against the other.
Check at normal speed first, then scrub any moment where fingers disappear, hair flickers, or a reflective object picks up part of the old room. A brief edge problem can often be covered by cutting to a full-screen view of the demo. If the issue runs through the take, try a source clip with clearer contrast between the subject and the room or refine the edges in your editor. Once the test holds up at the final viewing size, process the full take with the same settings and check that the audio is still in sync.
Reuse the presenter in a second edit
Keep the transparent download as your source. For a vertical social clip, put a brand color or an existing image on the lower track, then reframe the presenter and check the captions on a phone-sized preview. If you want BGChanger to generate a new room from a prompt or image, use its separate Video BG Changer & Editor mode.
