HELP! Preparing Video for Display Message + Out of Memory
I’m working on an HD TV project that originally was giving me severe problems.
The projecty was completed as an offline SD edit then media managed and the HD footage was captured and the clips were reconnected. There are multiple segments for the episode all in their own sequence. Then brought over to a master sequence with bars, tone, and slugs where appropriate. That has been the regular and successful workflow for the other episodes thus far.
Some clips (HDV, etc.) needed rendering. Normally I would highlight a sequence and render with no problem. This time it didn’t work so smoothly. When I highlighted a sequence it would render up to 99% then I would get the beachball for dozens of minutes forcing me to force quit. So I then highlighted each cut and rendered until I discovered a nested text clip in one sequence that may have been the cause (although I don’t think that was the only issue as there were multiple sequences all giving me the same problem). The text clip was on a separate video track then the picture video track and when you highlighted the video clips and rendered, FCP was OK.
My new problem with this same project with multiple sequences is when I drag a sequence over to a master sequence the “Preparing Video for Display” message which normally takes seconds to process is now taking upwards of 10 minutes. I didn’t nest the sequence because I’ve found nests within nests are problematic when we apply filters, etc. Final output has resulted in dropped frames, etc. Dragging the sequence over to a master sequence then applying a broadcast filter has been working much more consistently.
So I closed the project and reopened it. FCP was processing and reading the project (giving me the “Reading Project…” message which said “Preparing Video for Display” as it normally did. However, this time it took many many minutes until finally another error message came up saying “! Error: Out of Memory”.
Is it simply some corrupt video or text files? I’ve repaired permissions and reset PRAM but that’s not helping. What is going on and what are some solutions?

eh… How much memory do you have?
How many layers at once?
Effects?
What kind of disks are you playing back from? Are they ful?
(RAIDS slow down as they fill up)
What is the format of the final sequence?
Have you nested/mixed down audio before output??
Have you trashed prefs?Gunleik

This is the 10th episode of the TV show and previous episodes have worked fine. Not sure of the memory but I know I haven’t had problems before. 6 video layers and 10 audio layers. No effects, just some nested lower thirds with mattes, a few dissolves. Playing off a 4 TB raid with about 400 gigs empty. Format is HD 1920x1080i. I didn’t nest the sequences because we’ve had problems with nests within nests. Dropped frames on output. Haven’t trashed prefs yet. Will give that a shot.

Trashing prefs is always a good place to start. In case you have a bad render file, you could trash all of them and rerender from scratch. You could also try breaking the project into smaller projects, open them separately, then start building your project again from the ground up, to see when/where the issue starts coming in.
