Lina Edit turns speech into sentence and word captions on your computer. Select what to remove to cut the matching video and audio, then refine timing, trim pauses and export MP4, SRT or VTT.
Run speech recognition and every sentence and word stays linked to the video and waveform. Video cuts and caption timing have their own modes, so you can keep a shot and change only when its caption appears.

Refinement
Review silences and repeated words before removing them
Pauses and fillers like “um” and “uh” appear as candidates; listen before and after each cut and apply only the ones you choose. Replace wording in the captions you pick, and mark chapters where the topic changes.

Does Lina Edit need an internet connection?+
Only to download a speech model or demo video. After you download or import a model in Settings, analysis and editing run offline, with no account or media upload.
Which languages can it transcribe?+
Korean, English, Japanese, Chinese, Spanish, French, German, Vietnamese and Indonesian, or the language can be detected automatically. Whisper can also create English translation captions.
Which Whisper model should I choose?+
Clean recordings transcribe well with the smaller models; choose Small for noisy audio. At least 8 GB of RAM is recommended for Small and larger models, and accuracy varies with recording quality and background sound, so review captions and cuts before export.
Does editing change my original video?+
No. The original media is never modified. Edits are saved automatically, with recovery history, backups of previous saves and relinking if you move the source file.
