**System Information**
Windows 7 intel i7 nvidia gtx745
**Blender Version**
Broken: (2.73a)
Worked: (optional)
When merging png frames into avi file blender will suddenly lose frames in the export for no reason and no errors are given. No matter what file type it is, this will happen. Looks perfect in viewport but file is not.
I have reinstalled blender twice in attempt to solve problem and was unsuccessful.
Unclear as to cause and happens even when you reopen a fresh file and attempt to use sequences. will still lose frames
**Exact steps for others to reproduce the error**
No steps just simply add in frames and render it and sometimes it will do it and others it will not.
Based on a (as simple as possible) attached .blend file with minimum amount of steps
Unable to attach file due to the amount of frames that would be attached. (It would be about 1/2 a GB)
