Comment 81 for bug 520941

I am sorry to say that I was unable to resolve the issue in the end. I spent 3 days trying to make the libraries agree on the clip length to stop openshot getting messed up...I couldn't

I accept that my workflow is somewhat unusual, because I am effectively using "proxy clips" (see details on my workflow above) outside of openshot. I simple cannot edit my 1080p video using the raw footage..required performance is not even close..which is not helped by openshot using 30% of my CPU while idling on an empty project.

I have ordered a new machine Core i7 2600 with 8GB and a 2TB RAID 0 stripe disk because it will make life easier...however even with that my performance calculations suggest that I cannot edit using the raw mp4/libx64 clips. So proxying will remain essential

I tried with kdenlive which has proxy clips built in..and ...sorry...just worked.

kdenlive has bugs too..and it crashes...but this bug really cripples any half serious usage of openshot for me (perhaps it's caused by the bad mp4s my camera produces..although kdenlive handles them fine using the same underlying mlt).
