Hi there. Just to preface the issue, it's worth noting that I'm not very used to Sony Vegas and primarily used to work on Adobe Premiere. However I currently don't have access to the Creative Cloud suite and have been using a pre-existing copy of Sony Vegas Movie Studio 13 to edit some videos. I haven't been able to find an easy export file format for my videos (which are DSLR .mov format) in Vegas; on Premiere I'd export as either a MOV or a H264, whereas these don't seem to exist on Vegas? Or in the case of MOV, the data rate is limited to 3 mbps, which is clearly too low for high quality video. So I've been exporting as .M2TS, which is adequate enough for my recreational purposes.
However, I am regularly finding that exported files have segments of just still frame/frozen image in amongst the video - these are not intentional freeze frames, it is clearly an error during rendering. The timeline plays through fine. Wondering what you advise here to fix this, and also if there's a way to recreate the exports I'm used to on Premiere?
