Getting ready to generate Auto Captions
For the best and most accurate captions, Resolve prefers clear and clean audio track. A few simple tweaks can make your subtitles more accurate, meaning you spend less time correcting mistakes made by the machine.
Tip 1 – Mute Music
AI struggles with transcribing audio when there’s overlapping music.
- Mute music tracks while generating captions to get cleaner results.
Tip 2 – (Optional) Separate Speakers
Not required, but placing different speakers on separate audio tracks improves accuracy and unlocks time saving workflows.
Tip 3 – Plan Ahead with OBS
If you record gameplay or multi-source audio, many software/hardware like OBS lets you separate audios into different tracks. Doing this before recording makes editing later much easier!
Tip 4 – If Nothing Else, Use Voice Isolation
If you can’t separate audio tracks, apply Voice Isolation to your dialogue clips. This helps filter out background noise and improves transcription accuracy.
⚠️ Warning about voice isolation!
There’s a bug right now with DaVinci Resolve In Version 19
DaVinci Resolve can freeze if you apply Voice Isolation to an entire track instead of individual clips. To avoid this, always apply Noise Isolation directly to clips.
DO THIS ✅
NOT THIS ❌
Here’s a quick workflow work around until this issue is resolved:
- Apply Voice Isolation to one clip.
- Select the clip and press CTRL + C (Windows) or Cmd + C (Mac).
- Highlight the clips you want to apply it to.
- Press Alt + V (Windows) or Opt + V (Mac).
- Check Plugins under Audio Attributes and hit Apply.
Now, all selected clips will have Voice Isolation applied—without the risk of crashing Resolve!
