Hello, I have been using Vegas Pro 12.0 on a Windows 7 PC for 10+ years and just recently have had some weird rendering issues...hoping someone may be able to guide me on this. If part of the video project is rendered (as indicated by the black tiles at the top of the timeline) and I select a loop region outside of that already rendered area to render (with the "Render Loop Region Only" box checked), when it is done rendering it "unrenders" a random portion of the other already rendered area. Never noticed this issue before, and have not changed any settings anywhere that I can think of. Also, in rendered portions, a random clip might "hang" a second on playback after rendering, but if I would render to a file that apparent "glitch" would go away. Then if I rendered the whole project again that original clip would play back fine but another random clip would hang on playback. Anyone have any suggestions on this? Thanks in advance for your help!
