what it is quick time error -50 (in Compressor) I try to do a mp4.

A few weeks ago I did a quick time from my large project (with subtitles) with no problem. Today a copy from the same project but without subtitles. And it is impossible to do from FCP 7 a quick time. It is out of memory.

and sent to compressor 3.5 it error quick time -50.

I need a mp4. The best way would be with compressor but i cannot do any compression from fcp.Failed!!!!!!

Just a quick time form FCP7 with currents settings. But the result is not a good quality as with mpeg4 in compressor.

my film is 102 Minutes and it is a dv project 4/3.

I have fotos, logos, dv and a few HD ( in DV project).

I did with the same things last time and it was ok. Just the logo are news.JPEG 300dpi.

if someone can helped me I will be really happy.

I work on a macpro (2006) with ssd for my system and three harddisks in raid. (12 TB) for my project.

thanks.
