Field notes
The editor preview exposes a timeline with split, trim, zoom, and caption-edge controls, including 10 ms nudges and playhead cueing. The page lists MP4 output (H.264/AAC) up to 1080p alongside SRT, VTT, and ASS, and describes three Whisper model downloads of roughly 40, 80, and 250 MB. Its privacy statement says video decoding, transcription, timing, preview, and export stay on the device.
