music video editing
hello all,
can someone please advise me on something that is probably blindingly obvious but I´d still like to know.I will be editing a music video in the next few days. They are using playback from a dat recorder. What frequency should they use 44,1 or 48 Khz? And when I import the track into the avid, should I edit in 44,1 or 48? I know the end output will be 48 for video but does this mean I should edit in 48, even if they use 44,1 for playback on set?
They intend too shoot some takes at 33fps and speed up audio so that the takes will be lip-sync after I have loaded it in. Again, will this cause problems if they use a different frequency to the one I edit in?
Please help! Chris

It really shouldn’t matter what they shoot in vs. what you edit in. The problem comes when trying to change the sample rate mid-edit. You’ll see your audio drift pretty significantly. I would edit at whatever sample rate they give me, and I’d ask for 48k.

I agree with Jon, just ask for 48K.
Is this being shot on film? I ask because I’m wondering how they are going to shoot off speed and then get that back to you at the proper speed. This won’t be a problem if it’s film as they will adjust in the transfer.

Few points:
The playback sample rate does not matter, if they do a sample rate conversion. That way the duration stays the same.
When you edit, edit at 48 if you have to go to tape. Probably mean that you have to sample rate convert the music track, but again, speed does not change from that.What is important is that the cam is slaved to the DAT recorder one way or another.
Exactly for these kind of jobs i’ve created this:
https://www.videotoolshed.com/?page=products&pID=38Thus, you take one channel for music playback on the set, the other for syncing the cam. That can be done on the TC input, or put the LTC on an audio channel. Avid will read that just fine.
You then can use multicam or other tricks to get every shot exactly where it should go.The speed change is another nice gimmick.
For Terry, i think the plan is to play back the music off speed.
This way, the talent will act / sing too fast. For film, playback at normal speed will get things back in sync, for video, when slomo’d, they are in sync again.Nice effect! Should work sell too, but my TC trick probably won’t work. The clapperboard CAN however be of use.
It is absolutely no problem for me to alter the app, so it will let you run it slower/faster,
contact me (direct) if you want that.
If you use the visual TC to set your AUX TC manually, you are in sync again.
Perhaps the off-speed LTC can be read, but i doubt Avid is smart enough to notice that it is off speed, thus it probably starts counting from the first available TC.hth,
