HVX200 timecode problems
I’m working on a project which is being shot on the HVX200, with audio captured separately onto a hard drive. The video is transferred to me via a FireStore, and I import both the video and separate audio (which is recorded to four .wav files) using the ‘Import’ command. Both video and audio are captured using free run timecode.
When imported, the video and audio have wildly different timecodes. For example, the video clip whose timecode starts 08:47:39:02 has a matching audio clip starting at 13:39:36:09. What’s more, several of the video clips have the same timecode, even though they’re different clips! (Incidentally, all the audio and video clips are of different durations.)
I can (approximately) relate which video clip corresponds to which audio clip, as the FireStore includes time of day in the filename. But this obviously doesn’t help me with carrying out a frame-perfect sync.
I’ve been through my settings and can find nothing obvious that I’ve done wrong. Can anyone please think of anything that I could be doing differently which would solve the synching problem, or do I have to go back to the other guys and tell them the problem’s probably with them?
Thanks in advance for your help.

Since oyu can’t send tc to the HVX200, where was the audio recorder getting it’s tc from?

Did they use a slate on set?
Typically if you are shooting two system sound, you need a slate that has the scene/take info on it, and then the ac calls out that same info. When he claps the slate thats your sync point. Mark and in point on the clip at the moment the slate claps shut, then in the corresponding audio file mark and inpoint on the waveform where the clap starts. When you go to sync your audio and video, instead of using timecode, use “inpoint”.If you already knew this I apologize, im just throwing that out there.

Jeremy: the TC is being generated by the sound recordist’s hard drive recorder. I’ve just spoken to the sound recordist and the DoP and discovered that the sync on-set was done by reading the TC display and both trying to hit ‘REC’ simultaneously…
Daniel: I already knew what you were saying, but I appreciate your help anyway. They only used a slate in a few of the clips. If we can’t solve this problem any other way, then I’m going to have to go through each individual audio and video clip and sync them manually, using the method you describe.
Anyway, the DoP has re-examined his HVX and his FireStore and “discovered” some settings he didn’t know about, so the HVX will now have TC visible, and the FireStore will accept TC from the camera. There’ll be an offset between the camera and the audio, but it should be consistent across all the clips.
We’ll see if it works.
