Final Cut Pro – MultiClip – Audio not syncing
Ok, so I’m in a lil’ bit of a pinch here. FCP vs 6.0.6
I’m trying to create a multiclip from 3 different media sources. Camera 1, camera 2, and an audio source. The video footage from both cameras are ProRes422 (Transcoded from h264), full HD, at 30 frames per second. I’m aligning by placing an inpoint over the clickboard used at the shoot.
If I make a multiclip out of just camera 1 and camera 2, it syncs as I would expect it to.
The moment I try to make a multi clip of all three using the audio that was captured separately, camera 1 and camera 2 stay aligned, but the audio is way off. Oddly, it seems to ignore where I’ve placed the inpoint and skips five seconds ahead. In fact, in the multiclip, if I place it in a time line, I don’t even here the clap – it literally starts after the clap by around five seconds.
If I try to have a multiclip with just the audio and one camera – same results, no matter which camera (1 or 2) I attempt to multiclip the audio with.
Originally, the audio track was 48 Khz and 24-bit Integer, so I made a new version at 41.1 Khz and 16-bit integer (to be the same settings as the video audio
) either way – I’m still having the same alignment issue the moment the audio comes to the party. If I align all three (cam 1, cam 2, and audio) into a time line – it all syncs up just fine.
I need multiclip because I’m nabbing the selects for a production house, and if I don’t have multiclip built in they’d have to start from scratch to find my selects. Been chasing my tail on this for a while – any help is extremely appreciated.

They have a trial. It syncs by analyzing the audio. It’s very easy to use.

Thanks, but getting it to align isn’t really my issue – We shot with a clapper board, so I have great reference points for syncing. My issue seems to be that FCP won’t play nice with this audio in a multiclip – and I can’t for the life of me figure out why.
It’s ignoring where the inpoint is – but if I monkey around with the inpoint I can get it to sync manually, so the inpoint is having some kind of impact. It’s gotta be something silly right? Some setting/transcoding tweak somewhere?

Why did you convert the audio to 44.1? It should stay as 48 khz and possibly 16 bit. Although I think 24 bit should be ok. Maybe there was a shift in your conversion.

Hi thanks for your reply – I did that with just one audio clip thinking maybe it was off sync because the audio was 48 and the video’s audio was 44.1. I was trying to get everything exactly the same in an effort to chase down the culprit.
But, you are right – it made no difference. 48 khz vs 44.1 khz = same results for the problem here. I still have the original 48 khz file so will likely revert back.

Another question, you say you transcoded from h264. Why? Can’t you get the originals from the camera. Just curious as to why your originals are h264. thats a compressed codec. are there cameras that shoot to that?

Yes, we shot HD on cameras (Not sure which they were to be honest, they Canon SLRs that capture HD with H.264.) The audio isn’t coming from the camera but from a completely independent dat recorder.

You said you transcoded to 30 fps. Do you mean that literally, or is it 29.97?

Canon SLR’s don’t shoot video at 29.97fps. They shoot video at 30fps STRAIGHT UP. No wonder your audio won’t sync up.
This is a big issue with the Canon 5D. The 7D I hear does record 29.97, and 23.98. But the 5D only 30fps… but there might be some firmware update that fixed that. But that wouldn’t work for you, since you already shot the footage.

What is odd is that the audio does sync up if I put everything in a time line manually…with the same inpoints.
V1 – camera 1
V2 – camera 2
A1/A2 – audioThat works. It’s the moment I try to put the three of them in that pesky multiclip does the sky fall. And again, hoping to hold onto multiclip so when they take the selects that still have access to both cameras.

Try seeing if Cinema Tools can conform the 30fps clips to 29.97.
