Rendered footage not playing back smoothly

[John Pale]

It does. What are you using for drives?

Also, if there is audio, take a look at the audio track. Make sure it’s not some waxy sample rate, compressed, or mismatched with your sequence audio in some way.

I have an extra internal drive. It works fine for everything else. There is other footage in this timeline that plays back correctly. The audio is 16 bit, 44.1 mono.

Animation is not an editing codec so will need render. Uncompressed is good if your drives are fast enough, but why then use a DV sequence? Try to have your sequence and files matching, so an uncompressed sequnece is what you want

Audio should be 48khz.

[Mike Procyk]

The sequence is DV because other footage being used in it is DV. I know the animation codec needs rendering, and it has been rendered. The problem is it doesn’t playback well after rendering.

Does the render not also change the audio rate? Could that be the problem?

No. It does not, unless you tell it to. FCP will try to handle it in realtime, but not always do a good job.

Also, if the audio is compressed in some way and not PCM, this will cause problems even if you render it.

Thanks, I wasn’t aware that I needed to bring in PCM audio.

I’m assuming that if I did bring in 44.1 PCM and rendered, it would convert it to 48 (if that’s what the timeline is). Is that correct? Of course, from now on, I’ll just do it before import.
