Bystream Tool

🎬 STUDIO — remove the green screen, replace the background, and overlay multiple product images / multiple promo clips. Configure once and it applies to every video in this stream. Rendered once, re-rendered only when you change something.

Remove green screen + replace background

Replacement background image/video:

The background can be an image or a short video (looped seamlessly and baked in at render time, so playback stays light).

Key colour · Sensitivity 0.12 Green spill removal 0.5 Edge softness 0 — 0 keeps the subject solid. Raise it only when clothing/skin is far from the key colour, or the subject goes translucent Shrink edges (clears leftover hard fringing) Adjust subject position/size (drag the orange box)

📐 Video frame (for footage WITHOUT a green screen — drag the white box)

Scale or move the whole video into the safe area so phones do not crop or cover the presenter. Empty space is filled with a blurred copy of the video. Frame size 100% — below 100% shrinks the whole video; above it zooms in and crops the edges.

Product images (add several — drag the cyan box to place them)

Promo clips (add several — they run throughout, muted; drag the purple box)

AI sticker (on by default)

⏩ Playback speed — 1 keeps the original, 1.2 is 20% faster. Changing the speed re-renders the video (a few minutes on the next Go live).
