I am running into the SAME problem that original poster did. I am trying to convert .mp4 (h264) to prores (422) so I can edit in FCP. Both Quicktime 7 and Media Streamclip can play the footage but neither can convert to pro res.

In QT7, i get a smaller file that is WHITE.
In Stream clip I get the error “Can’t Prepare the Movie”

I have Perian, VLC, H264 Codec installed etc…same problems. Any ideas?

Download the Fully functional Trial Version of Media Composer 3.5 from Avid.com, you can try it for two weeks free and hone your chops for your first Avid gig.

UPDATE. After doing several un-installs / re-installs, finally got the MOJO analog to be recognized by Media Composer 3.5

It took a much more intensive un-install then just using the un-install applications. Using this link from the Avid Knowledge Base,

https://avid.custkb.com/avid/app/selfservice/search.jsp?DocId=274687&Hilite=uninstall+uninstall+procedure

Had to go into various folders and manually delete some files AFTER using all 4 of Avid’s Uninstaller programs. Then emptied trash, reinstalled MC 3.5 and the Mojo worked.

Thanks to all who chimed in and I hope this helps anyone with further issues on the subject.

Thanks to all who have responded.

RE: The Firewire 400port in the system…

The Mojo did work on the FW card with Xpress Pro, when I upgraded to Media Composer 3.5 it stopped working. So what you are saying is that Media Composer 3.5 could quite possibly not be compatible with the a Firewire port it was once compatible with in Xpress Pro?

I guess I wouldn’t put it past AVID. Where do I find the specs for MEdia Composer Hardware requirements that are as detailed as to which FW 400 ports are compatible.

Has anyone had any success using the FW 400 port in the back (or front for that matter) to connect an MOJO analog to a Mac Pro 3.0 Quad Core Tower?

RE: Reinstalling the system.

Should I completely wipe off the system drive and start from scratch? I have reinstalled MC 3.5 several times…man this is frustrating.

Avid forces you to only use their hardware for breakouts / previewing etc, but then they have massive compatiblity issues. It’s just a bummer.

Is there any tangible difference between the Academic Version and the Upgrade version besides branding and or price point? Is the software identical or are there any technical limitations to the Academic version.
