Well new processor (intel, old was an AMD) new MB new Install of windows and Vegas and all plug ins and the dreaded black Frames are back! Render to m2t I get black frames, audio drop out a the same place at times. Tried every combo of FX on, FX off, ram settings, no smart render of m2t's they are still there.!! other formats render fine mpeg for DVDA , CFDI etc.
What gives???
Sent in a tech support request, but is any one else still seeing this, could it be some of the plug ins? All i have are V8 comppliant as far as i know.

I get them...but not in my final renders...and it may have to do with my workflow.

I still use Gearshift and work with proxies and get an occasional black frame. However, a quick switch/swap to the m2t file and it gone....

anyone else using Gearshift seeing this also?

Any time I do a large project with HDV footage I have problems. I'm working on a project with stuff shot on JVC HD-250's in 24P & 60P. Haven't had a problem until this week when I started adding a lot more footage into the project.

All the sudden I am getting all kinds of crashes - especially when trying to pre-render or render to a new track. Very, very frustrating. I thought about trying to get the project back into V7 but I don't even know if that will be any better.

It is getting to the point where, despite how much I love Vegas, I will probably bring HD stuff into FCP via HD-SDI and just edit it in Final Cut. I can't handle not knowing whether or not the project is going to render or not.

My general rule of thumb when using HDV is that if the footage was acquired on tape, use Cineform. If it was acquired tapeless, use m2t native. IMHO, HDV shot to tape simply isn't stable enough to use without immense frustration. Mt2 recorded to compact flash on my Z7 is rock solid however and a totally different experience than I had with any of the tape HDV cameras I've used before. HDV recorded to tape on the same camera (my Z7) is just as crash prone as any other HDV camera.

Here's another issue which may or may not be related to the "black frame" bug. The video (two camera HDV edit) looks and plays just fine in Vegas, but when I do my final SD MPEG2 render, a few bad GOPs are generated! Vegas didn't make any complaints, errors or warnings, just generated the bad MPG output and left me to discover it on my own. At first I thought it was a DVD-A issue so I posted my experience there:

Thanks for the reply LReavis. One other oddity about this, i have NEVER had the problem when editing short clips, 2 to 4 minutes. The clips in question were around 15 to 20 minutes.
A mention was made to render out into something other than HDV, I have not been rendering to HDV, the black frames are in the captured footage, and appeared after I started editing.
