FCP converting audio sample without reason
on Sep 20, 2013 at 12:24:19 am

Hi guys,

I'd reading lot of threads about issues with sample rate convert, most of times involving 44.1 and 48.0 KHz. But my problem doesn't refer to a difference of samples rates.

At my work I'm using FCP 6.0.5 and always have dealing with 44.1KHz. So is the standard project sequence set to 44.1, never had problem with this in almost two years.

But now FCP began to write the audio every time that I render a transition, then appears the blue line on the audio track indicating the audio was converted. But wasnt green before. There was nothing, like is normally.

The other editor says to me that was canceling the conversion. This resulted some exports with audio sync problem, but someones exported ok.

This issue is not blocking my work, but I need edit classes beyond 2 and 3 hours, cut 30 min parts, and now have to wait 2 min every time I render a transition. Just because FCP wants to convert 44.1 audio in a 44.1 sequence to create another 44.1 audio. Doesnt make sense to me.

I tried create a new project, but the same thing still happening. Must have another settings that Im not considering?

Thanks for atention.


My sequence setting are:

854x480
square
Field Dominance: none
29.97
Compressor: apple intermediate codec
Audio Rate: 44.1 kHz
depth: 16-bit
Config: Channel grouped

My videos are:

854x480
square
29.97
apple intermediate codec
44.1 kHz
16-bit integer
