Shortsly- PrepareRecord a short clip against a clean, evenly colored green background.
- UploadAdd it through Use as filmed so Shortsly keeps the original pixels.
- StudyLet Shortsly identify the visible subject, action, text, and useful moments.
- KeyRemove the green background in the editor and inspect the transparent edges.
- SaveStore the keyed clip in Assets so it can be reused in later videos.
1. Prepare a clean green-screen clip.
Use a flat, uniform green background. Avoid gradients, visible texture, strong shadows, and changing exposure. The cleaner the color is, the easier it is to remove without damaging the subject.
- Keep green clothing, graphics, and reflections out of the subject.
- Leave clear space around moving hands, products, and screen edges.
- Use even light to reduce green spill around the outline.
- Trim the source to the useful moment before uploading it.
Shortsly accepts clips up to 60 seconds and 100 MB in this flow. MP4, MOV, and WebM files are supported.
2. Upload it through Use as filmed.
In the composer, select Use as filmed and choose the green-screen video. Do not add it through the photo control used to restyle images. Use as filmed tells Shortsly to keep the original clip instead of repainting it into the project style.
Leave Study selected before adding the file when you want Shortsly to reuse it automatically. Shortsly examines the visible subject, action, text, framing, and useful moments. The modal shows the required credits before you confirm the upload.
Study prepares the clip for later matching from Assets. It does not remove the green background or apply chroma key, and it does not replace the editor steps below.
3. Create the video and find the clip.
Create the video after the script, voice, source media, and visual style are ready. The original green-screen file stays unchanged during generation. Chroma key is an editor step, so seeing green in the editor before you apply it is expected.
Open Media, choose the Project tab, and locate the uploaded clip. Check where it appears on the timeline. If the first placement does not match the intended line, add it at the playhead, replace the selected clip, or move it to another track before processing the background.
If you are starting from a script, the complete script-to-video workflow explains how to review the narration, scenes, captions, and pacing as one story.
4. Remove the background with Chroma key.
Open the clip card's three-dot menu and select Chroma key.... The panel starts with a green key color. Use Pick from canvas when the recorded green does not match the default exactly.
Adjust Tolerance first, then Softness. Watch thin details, rounded corners, shadows, and moving edges while you tune the controls. Select Apply when the background is transparent and the subject remains intact.
Shortsly creates a transparent WebM file and updates every use of the original clip in the current project. You do not need to replace the clip on each timeline track.
- Key colorChoose the green to remove.
Start with #00ff00 or use Pick from canvas to sample the actual background.
- ToleranceControl the color range.
Increase it only until the remaining green disappears. Too much can remove detail.
- SoftnessBlend the edge.
Add enough softness to reduce a hard outline without making the subject look blurred.
5. Watch the source clip and finished video.
Preview the full scene after processing. Look for a green fringe, missing parts of the subject, transparent dark areas, or a soft halo that becomes visible over the new background.
Check the clip while it is moving, not only on one paused frame. Motion blur and reflections can reveal keying problems that are easy to miss in a still image.
6. Save the transparent clip for future videos.
Open the updated clip's three-dot menu and select Save to assets. Do this after applying chroma key so the reusable file is the transparent version. Give it a clear name that describes the subject and action.
In a future project, open More options, find Assets, and keep Use my library enabled. Shortsly can compare saved media with the script and suggest the saved clip when the visible content fits the scene. You can also use Add assets to select it manually.
Shortsly can choose a useful moment, fit the clip to the vertical frame, adjust its scale and position, and plan its entrance and motion. Review the resulting timeline before export, especially when several saved clips show similar content.
