Finish the reel without starting over.
Open a generated reel on a real timeline: cut what drags, reorder scenes, style captions word by word, layer in music and voiceover, then re-render the exact same footage with your edits.
- Trim + reorder scenes
- Word-by-word karaoke captions
- Re-render, never regenerate
Caption studio, Caption Studio is SocialCTL's timeline editor for generated reels: trim and reorder scenes, style word-by-word karaoke captions with animated presets, add layers, music, transitions and voiceover, then re-render the same video with your changes applied. It edits the reel you already made, reusing your footage instead of regenerating it.
Scene-level control
Trim, reorder and retime the scenes of a generated reel on a familiar timeline.
Karaoke captions
Captions highlight word by word in sync with the audio, with animated styles to pick from.
Layers and audio
Add overlay layers, music and voiceover on their own tracks, timed independently of the scenes.
Edit, then re-render
Your footage stays; your edits apply.
Caption Studio never throws away the video you generated. Every change, from a trimmed scene to a restyled caption, is applied to the existing footage and rendered again as a fresh MP4. That makes editing safe: the shot you liked is still the shot you get.
- Same footage — Re-render reuses your clips; it never regenerates them.
- Precise cuts — Trim and reorder scenes exactly, down to the moment.
- Captions in sync — Caption timing follows your edits, so cut scenes never leave stray words.
