Sony Vegas 11 Pro Rendering

[StarGreen]

From 1.6 onwards, recorded footage can be viewed and edited in Sony Vegas, but rendering results in an application crash with the following error message.

I've bolded the obvious section related to Action! - Any hints on to what this might be?

Does it happen with all recordings?

Please provide us some recording details (resolution, duration etc) and your rendering settings,
we have used Vegas 11 in our labs successfully and have not noticed any problems.

OK, other short videos of 1-2 minutes recorded in 1.61.1 render out fine. However rendering an 7 and a half minute file crashes at 47% over and over.

Recorded DayZ in 1080p, 60FPS. Rendering as .wmv/.mp4/.avi at same specs or 720P @60FPS results in the same crash.

Im gonna record another piece of similar length footage again and see if maybe its just one file? But the file plays flawlessly, so Im unsure.

EDIT: Another 25minute file rendered fine from another game, and a further 7 and a half minute file from DayZ rendered fine, so I assume its just the one file that may have an issue, not the decoder in general.

OK So its nothing to do with Vegas, its Action!. I recorded the file playing with desktop recording at the same settings and the video playing eventually came up to a frozen section which I assume is what all the other programs were failing to get past. Im attaching the video of what happens at this point: http://youtu.be/nT-ix3huLYs
