Please, do yourself a favor and don’t. There will be no savings, because you will have lot’s of troubles in post.

FCP (and other NLE’s) has difficulties with different frame-rates. The worst is your audio slipping out of sync. FCP can resize different formats quit well, it can loose a bit of sharpness though, but audio…

I had this case were audio slipped 5-10 seconds (!) out of sync…
You know how it goes: a friend doing a friend a favor, and I doing him a favor promising to author the dvd. The timeline played fine, all mixed formats (30 I guess frome an iPhone, HD 25, 23.98, super 8 film converted to something… H264 codec in the timeline, stills, animated stills, nothing pre-converted) Well, all the don’ts were there. And it showed when compressor it to mpeg2 (why only then murphy). Even chopping the audio in small blocks in soundtrack didn’t work. What worked in the end was to put the sequence in a new timeline and let FCP render it. The strange things was that a ProRes timeline didn’t work… (perhaps I had a setting mistyped, to be investigated the next time), but a good ol’ simple DV25 worked…

So, don’t be penny wise and pound foolish. You will almost certainly get audio slipping out of sync.

Hi,

As stated above, you can have DV 48kHz (=2 channels, 16 bit) and 32 kHz (=4 channels, 14 bit). So the latter has less quality. Reading the posts above, it seems you have 32 kHz. You have already made a new capture setup. Have you also changed the settings of the timeline? Else you have to render (FCP can do it on the fly/without render, but I have heard many stories of the audio drifting out of sync).

Try to make a new timeline with 32 kHz. Does that help?

Be warned, I also heard many stories of audio drifting out of sync with DV 32kHz If you have long takes even with all setups correct. And also with other NLE’s (not sure, never used 32kHz), but it seems to be a DV codec issue. (Basically, never use 32 kHz, but that’s to late.)
