Finish a Short Video with Checked Subtitles and Sound

A video in the required aspect ratio with accurate subtitles and intelligible sound, keeping source material and project files.

Before you start

• The audience, script, duration and aspect ratio
• Permission to use the footage, people, music and voices

Suggested workflow

1. Break the script into reviewable sections

   Define what the viewer should understand. For each section, list the real footage, illustrative material and narration they should see or hear.

2. Choose tools around the material

   For existing recordings, start with Descript for transcripts and subtitles. Compare dedicated tools separately if you need generated clips, narration or avatars.

3. Check picture and sound together

   Verify terminology in subtitles, narration pauses and volume. Check continuity in generated visuals and clearly distinguish illustrations from real footage.

4. Play the complete export

   Watch the final file on the target device. Inspect the opening, transitions and ending for black frames, clipped text or missing sound.

Check before delivery

• Do subtitles, names and numbers match the actual narration?
• Is the video understandable on a phone speaker and small screen?
• Is the use of people, voices, music and other material authorized?

Limitations

• Generation credits, processing hours, watermarks and commercial terms differ between tools.
• Do not imply that generated footage records a real product test or a person's statement.
