Worked just fine

Short description of error When i trie to render an animation with the format quicktime the program just crash. I have tried several times on different files with the same result.

Exact steps for others to reproduce the error I sate al frames and had al settings ready, i put output format to quicktime and then hit render animation.

Based on a (as simple as possible) attached .blend file with minimum amount of steps

2.68 is old, please try with 2.69 or a daily build from builder.blender.org.

Also please don't paste these long error reports in your description, rather attach a .txt file, helps readability here a lot. ;)

Same problem when rendering a still as .png, .jpg or .tiff with Blender 2.69.8 e07e8e3

The 32-bit version works fine (8ff58ee) (just tried .png)
(Mac OS X: 10.9.1 on CPU)

Jens, can you please check on this? Strange that it works with the 32bit version.

@fredvomjupiter, the issue that you are seeing is likely unrelated to this, the crash log indicates a quicktime specific issue.

It's also not clear to me what "rendering a still as .png" means. If you render a still image it is not automatically saved to file, the chosen file output type does not affect anything when you press render. When does it crash exactly? When you press render, when you save the file, .. ? And does it happen with the default cube or only particular .blend files?

I can confirm this Quicktime crash in the 2.69 32 bit build and my own 32 bit build from latest git. That crash log also indicates x86 which is 32 bit. The workaround is simple: just use the 64 bit build, since you are running OS X 10.8.5 it should work fine.

Developer Note:

Reading the Quicktime documentation, it does indeed seem to be the case that you are not allowed to create movies on non-main threads, but somehow it works on 64 bit, not sure why.

Also note that after 2.69 we removed the old Quicktime API backend and switched 32 bit to QTKit, the same as 64 bit was already using. This however does not make any difference, it crashes in both cases.

I guess the solution is to restructure the code such that the initialization runs on the main thread, but that's really quite tricky.

@brecht, is it just making it so video descriptors are initialized from main thread and writing frames from non-main thread will work fine?

I just tried with Mac OSX 10.9.3, 50 frames of a moving cube, saving as Quicktime MOV. This was compiled from source (x86_64 arch) with code from last week (technically, 2.71 from 7/19). No crash, and I was able to play back the MOV. Also, not that it is probably a big deal, I can't find any attached *.blend files.
*UPDATE: I just saw that this only happens in 32-bit builds. Please ignore my comment!

This issue will be a nonissue soon, as we drop 32bit anyway ;)

Closing this task for now.
