No credits · sidecar files

Your SRT appears here. Paste the talking-video script, set the duration, then pack.

This page times the words you paste. It does not transcribe a recording and it does not spend credits. Generate the face on a talking tool first if you still need an MP4.

この ai字幕 ページがある理由

Same words the mouth already used

Captions that disagree with the visemes are worse than no captions. Paste the script you generated with.

SRT and VTT, not a burned overlay

Players, YouTube, and most LMS tools want a sidecar file. Fancy styled captions still belong in an editor.

Timed to the clip you set

Cues share the duration by word count. Trim the talking job to the same length or the last cue will drift.

No credit meter on this page

Packaging a transcript is local. Lip-synced video still uses 150 credits for the first 30 seconds.

    ステップ 3

    Download SRT or VTT

    Attach it in the player. Then go back to the face tool if the mouth still needs a pass.
