Glitches when exporting movies from FCP
This is an issue that’s beginning to aggravate me somewhat as it’s quite a timewaster. I’ve noticed when exporting movies recently from FCP that I’m getting more and more ‘glitches’.
I first noticed it when exporting a ‘legacy’ project from V5.1.4 times (approx. 12 mins very quick cut). This project had been media managed and archived etc. so I put it down to the age of the project and the fact that it had been so ‘processed’.
However it’s become more of a frequent occurrence.
The ‘glitches’ are intermittent and render the movie enough times and you get a pass when none are present. They usually take the form of a horizontal line approx. 10+pixels high and multicoloured (bright greens / magentas etc.). I’m suspecting that it’s just some minor file corruption (I say ‘just’ lightly).
I’m running OS X 10.4.11 – FCP 6.0.2.
Any suggestions or thoughts would be quite welcome.
Many thanks..

First, I would dump your preferences.
Can you tell us what codec you’re editing in? What are you exporting to?

Russell,
Cheers for your reply. I have had a number of ‘preference dumps’ in this time – but my settings have been :-
The original timeline was DV PAL and had corruptions exporting either as a straight FCP ‘export as quicktime’ from the timeline or via compressor as an MPEG2 for DVD. It did eventually work but only after a number of attempts at getting a clean movie.
The latest was a 1080 pro res HQ timeline and had the same issue as a straight export as quicktime and an attempt at 10bit uncompressed via quicktime conversion.

Strange. Have you added extra RAM to your computer? It’s possible that that could be causing the problem.

Russ,
Hmmmmmmmmm………….. That’s a sharp insight……
Yes, we have added additional RAM in recent months. We’ve added an additional 4x2GB crucial RAM.
What effect might this be having – and what’s my solution.
Many thanks for taking time to work on this issue with me.

Sometimes bad RAM can make a system to really strange things. Crucial’s a good company, but if you keep having the problem, try pulling out the RAM to test if the problem still exists.

Russ,
Had an opportunity to test the RAM with this project on Friday. Have been on other projects until now.
Render 1 – Both old and new (crucial) RAM – very occasional glitches
Render 2 – New (crucial) RAM only – very occasional glitches
Render 3 – Old RAM only – glitch free – Crucial RAM goes back today for replacement…..Thanks for the heads up on that one Russell – the errors were so minor and infrequent, but on fairly longform (12minutes+) projects – they were causing me a real headache. I don’t think that I would have reached a RAM conclusion if it wasn’t for your steer.
Great result – many thanks.
Mark
