Hi everyone,

Sony Vegas 10.0e


Have been having issues with various edits. Usually on HMC footage but have experienced it on a few different cams. When editing a clip will sometimes turn grey on the timeline and when I put the cursor over it or play that clip on the timeline it is black in the preview screen. Sometimes the clip will appear fine on the timeline but then when I render the full video, some clips appear to be blacked out. It also is random clips not just one that may be corrupted or something. Have no idea how to fix this. Any insight would be appreciated. If you need more details just let me know. Thanks a ton in advance!

ok....

if you're NOT heavy fx / cc'ing, i'd simply convert them to .mxf and play happily ever after.

i know there's a lot written about cineform, etc., but afaic i've had no problem converting 'odd' codecs to mxf, nor seeing any degradation that would have me in the least bit concerned.

Ben go have a look at this thread:
http://www.dvinfo.net/forum/cineform-software-showcase/499627-random-black-frames-when-rendering.html

I've been having the same problem but I've isolated my problems to Cineform I think, chime in we need to get support for this issues it's a huge headache.
