When playing certain clips in a video I am creating in Sony Vegas Pro 12, SV (Sony Vegas) crashes. However, when playing other clips, they don't crash SV. I used DXtory with the Lagarith Lossless Codec to record all of the clips, and they are a mix of Battlefield 3 and Battlefield 4 clips. All of them have been split/trimmed, and there are no added effects yet.
There will be an attached video explaining what I mean.
