what does this mean?? cannot export a sequence nor a clip.   avx 5.7.2

It means somethings wrong...  

Can you give us some more information?  What are you trying to export, format, sequence settings, media type, resolution, platform, OS version, QT version, etc.?  Can you export sequences or clips from other bins or other projects?  Have you tried cutting the material down to smaller parts to isolate a potential problem area?  The more information you post in your inquiry the better the chances you have of getting a quick and accurate response.

 And you can start by going to and completing the section in your user profile on system specifications. You'll find it under profile options.

Then, check your QT version and drivers against this matrix to see if you're running the correct ones.

Then, come back here and list the exact options and parameters of your current export profile that you're having issues with.

thanks for intensions to help me! in fact with this system (brand new, got it some days ago only) i cannot export a sequence for a quicktime movie or quicktime reference, i always get the above answer. otherwise i can export tiff, pict and other graphics or audio files like omf.

even after a batch capture it is not possible to export my sequence.

What OS X version?  What's the path of the file you're trying to export?  What's the name of the file?  What format is your media?  What format are you trying to make the QT?  Hard to see what's happening at your end....

ok, i have installed MacOS 10.5.3 with MC 3.0 uand QT 7.5. The media files are from a editing session over some month and as long i did work with AVX 4.8.4 on MacOS 10.4.6 with QT 7.0.3 everything was working well.

I can now export normal graphic files like tiff. but no sequences.

 QT 7.5 is not supported for MC 3.0. According to the system requirements, you should be using 7.3.

ttp://support.apple.com/kb/HT1222   confirms the automatic installation of QT 7.5
