Must render everytime at DVinfo.net

Joe Riggs · March 31st, 2010, 06:51 PM

Hello,

New to FCP, moved from Premiere. In FCP 6 every time I adjust or move the audio, I must render. I have checked the sequence settings vs. the clips and they match.

What I discovered is that I can only layer 4 audio tracks, any more and I must render. Is this typical? Anyway to increase it? I have 20 audio track that need to be layered.

If not, is there a way to disable the beeping sound? That way I can make all my edits, then render once.

I am on the latest Mac Mini with 4 gigs of ram.

Thanks

You can change the number of Real Time Audio Tracks as shown in the attached photo from 4 to 20 but I would imagine you'll have playback issues with 20 tracks. The RT AT setting is set as a WARNING and doesn't actually control how many tracks play back seamlessly.

FCP isn't really set up for mixing so 20 tracks is KIND OF a large number of tracks to be working with in FCP. Good luck and let us know.

Thanks, my project is already set to 8 real time audio tracks. I guess 4 tracks is the max my computer can handle? Can anyone confirm that they can layer 5 or more tracks, and make adjustments without the need to render?

Anyway to eliminate the beeping noise?

What sort of audio files are you using? AIFF? If not, you may need to covert the tracks before bringing them on to the timeline.

All 48KHz, 16 bit of course? <sorry, gotta ask>

Joe,

As with any edit system there is a "point of extinction" where the amount of content you've put into your timeline simply overwhelms the resources available to the hardware for real-time playback. At which point you'll have no options but to render each time you make any change.

However there are a few things you can do to help your system: In RT playback settings you can select a lower quality setting both for frame-rate and overall quality. You can even select 'lowest". What will happen then is that when you do playback the timeline it will be in low-res "proxy" mode rather than full-res, and only show full detail when the playhead is paused.

As SR pointed out, making sure your AIFF's are 48khz will also prevent renders.

But as any project gets larger you'll simply run into the POE situation eventually, and since you're on a system with very limited resources I'd say you're probably near or at that point.
