It’s called AutoSync – if there is no common timecode anywhere, it can be done manually.
1. Mark in at clap on video only clip
2. Mark in at clap waveform on audio only clip
Bin menu – AutoSync – check based on IN and click OK
You can then slip by 1/4 frame fro tighter sync if in 35mm project.
The user guide or online help should have a good description on that – do a search on AutoSync.
