Real Time Improvement When I Export?
FCP Newbie Questions:
I can’t get my 1080 Prores timeline to play back in real time unless I’m on unlimited RT, Medium playback quality and half frame rate. I did everything Apple suggests to improve playback, turning off external monitors etc. There are no effects on the timeline. I’m using a brand new 8core MacPro 8GB of RAM with a Caldigit HDOne hard drive (which is more than enough for real time prores)Is this typical performance?
I can live with the annoying jittery playback but my question is when I export the timeline to Quicktime or to Compressor to make a DVD, will I get real time smooth performance with the new media? And will FCP automatically playback the highest quality when exporting or do I have to manually adjust playback quality to the highest setting before exporting?
Thanks

sounds like your prores media and your sequence settings do not match.
What flavor is your prores? 1080/2398?
What are your sequence settings?
when you export everything is full quality.

Sam,
Something is amiss, because your hardware is more than capable of playing back ProRes in realtime.
How long have you had this system? Is it new?

I got it last December.
My monitors are hooked up to an AJA ioHD box so the sequence setting is:
AJA ioHD 1080i 29.97 Apple ProRes 422HQ
Playback setting:
AJA ioHD 1080i 29.97 ProRes 422 (HQ) (1920×1080)
You think the preset might be wrong?

I’ll bet that if you were to open a new (non HQ) ProRes sequence you’d be good to go without any issues whatsoever.

You mean just copy and paste the shots from the existing timeline into a new non HQ timeline?
-
You can do that, or simply change the compressor in Sequence>>Settings to the non-HQ flavor of ProRes and re-render the sequence.

David…I tried your suggestion with no luck.
What was happening is the timeline would play OK for 2 seconds or so then freeze for half or a full second and that would repeat. It got worse as the playhead moved down the timeline.
So I began to think maybe it isn’t a frame rate error even if reducing the framerate to half got rid of the problem. So I began shutting tabs. I had about 10 open because the timeline was split into ten different sequences. So I shut them all except the one I was working on. I also shut the effects tab and a couple of tabs for music and graphics. And that seems to have solved the problem. I now have smooth playback.
So do you think this was some kind of memory problem? Too many open tabs at once draining memory?
-
Yes, that clearly points to a memory issue from too many open timelines.
