video-editing

Use ffmpeg -i raw.mp4 -ss 00:12:30 -to 00:15:45 -c copy segment.mp4 to extract a segment without re-encoding. For batch cuts, loop over a cuts file containing start, end, and label values and run the same command per line.

Use the FFmpeg crop filter: ffmpeg -i input.mp4 -vf "crop=ih*9/16:ih,scale=1080:1920" vertical.mp4 for a center crop. For subject-aware reframing, VideoDB offers a smart reframe mode that tracks the subject automatically.

Use Remotion for programmable, repeatable elements like text overlays, lower thirds, data visualizations, and reusable scene templates. Traditional editors like Descript or CapCut remain better for final pacing, captions, and color grading.

No, this workflow is designed for editing real captured footage, not prompt-based generation. AI generation with ElevenLabs or fal.ai is used selectively only for missing assets like voiceover, music, or insert shots.

Run ffmpeg with the silencedetect filter: ffmpeg -i input.mp4 -af silencedetect=noise=-30dB:d=2 -f null - and parse the logged silence timestamps. Combine these with transcript analysis to decide which segments to remove.
