After a bit of digging around I managed to find a newer version of Cinelerra for Centos 5 in the ATrpms repository which rendered my transitions correctly after I installed it. It also prompted me to run echo "0x7fffffff" > /proc/sys/kernel/shmmax when it started up. I'm not sure if it was the new version or the increased shared memory which solved the problem but now I can go crazy with transitions. I'm going to leave the cupcake video as is but will use transitions sparingly but to great effect in my next video.

When I was working on my HD masterpiece. How to Make Bacon Chocolate Cupcakes I need a video editing tool to run on Centos 5. I had a bit of experience with Cinelerra from when I had used it to edit my How to Make A Guitar Pick From a Credit Card video. First observation, Cinelerra crashes a lot, so much in fact that it has a restore option on the menu to reload your project after a crash and checkpoints changes to the recovery file after every change.

After getting the edits done and enduring quite a few crashes I tried adding some transitions, wipes and fades where I wanted to show the passage of time. Unfortunately every time I tried to use one the render would freeze in the middle of the transition. I tried a number of different transitions but was never successful in getting one to work. I tried to use the latest version of Cinelerra in case the problem had been fixed in a later version than 2.1-0.14 which was the version available for Centos 5. Even though I got it to compile it crashed almost immediately when I ran it. In the end rendered the video without the transitions, you can see the results below. If anyone has ran into the transition render freeze issue and knows the solution please let me know.
