Hi, I am trying to edit my video with Sony Vegas Movie Studio Platinum Pro 9.0 - recorded with a Canon HF10 HD camera. I imported the movie clips to the timeline by using "Import AVCHD camera". That worked smoothly. Then I tried setting the project settings so they're identical to what Vegas says the movie clips are (framerate, resolution etc.) - then rendered the movie and burnt in to a DVD (only a small clip so It could fit on a DVD). To do that I clicked "Make movie" -> Burn it to a DVD, Blu-Ray disc, or CD -> Blu-Ray disc I used these 'render parameters': Video format: Sony AVC (*.mp4,*.m2ts,*.avc) Video template: Blu-ray 1920*1080-60i, 16Mbps video stream Audio format (only 1 option): Sony Wave64 (*.w64) Audio template (only 1 option too): 48.000 Hz; 16bit; Stereo, PCM This worked with the small clip - but when I then add some more clips to the timeline and try rendering and burning, the program crashes at the rendering process. I even tried just rendering a small part of the movie by making a "loop playback" region and then check the "render loop region only". What could be wrong? I know the rendering is ressource heavy but I got a Intel Core2 Quad 9450 cpu @ 2.8ghz and 4gb memory - running windows xp. This should be enough to handle the rendering.. I tried rendering with these render parameters too: Video format: MainConcept MPEG-2 (*.mpg;*.m2v;*.m2t; *.mpa) Video template: Blu-ray 1920*1080-60i, 25Mbps video stream Same audio settings as before This time the rendering worked fine - took app. 50 mins to render a 22 minutes movie - it appears to me it is faster than with the other settings (the video preview shown while rendering seems more smooth now). I rendered the whole movie and unfortunately it ended up being a bit too big to fit on a DVD so I tried to render and burn just 2 minutes instead for a quick test with these settings. I did this, it worked, but when I insert it into my blu-ray player the movie isn't smooth - it's plainly unwatchable. It looks like the first 5 seconds are smooth, but then it starts to clutter and the sound disappeared. I would really appreciate if anyone could help me fix this problem - I have tried so many different programs (Premiere pro CS3, Pinnacle Studio 12 and now Vegas) to edit the video from my new HD camera - so far with no luck Thanks in advance.
