GH3 Glitch with Sony Vegas

It seems that when you drop a 24p 72mbps clip into Sony Vegas, the video is about 5 times longer than the audio, and everything beyond the audio is a still of the last frame. This only happens at 24p 72mbps, the other codecs work correctly. Same on 3 version of Vegas (10 through 12) on 2 computers, it didn't happen in After Effects.

Re: GH3 Glitch with Sony Vegas

Good heads up. Will make sure to use 50Mbps only when using Vegas with a GH3. If I want I-frame in Vegas, I guess I'll go the Nanoflash route.

Re: GH3 Glitch with Sony Vegas

Could also be my camera and not all GH3's. Anyone else able to duplicate this?

No problems in Final Cut Pro 10 with 70 all-i.

I had a similar issue with some sample GH3 footage I downloaded back in November. I had assumed it was because it came from a pre-prod camera. Here is the source:

As you said, the interesting thing is that the last frame is the only thing that goes beyond the end of the audio - the track does not loop for me. This is with Vegas Pro 10...

Re: GH3 Glitch with Sony Vegas

I shot one clip at 24p 72mbs setting today and get the same results in Vegas 12 as Duane did. I have been using the 30p 50mbs for all of my work except this test and there is no problem with that setting.

In regards to the extended video with 72mbs, it seems to play OK if one grabs the end of the clip and drags it back to match the audio.

Re: GH3 Glitch with Sony Vegas

Yes you just size the video to match the audio so it's an easy workaround. Hopefully it will be fixed in a future update.

Re: GH3 Glitch with Sony Vegas

Don't forget to disable resampling otherwise you'll cause ghosting in the image.

Re: GH3 Glitch with Sony Vegas

I just downloaded the trial of Premiere Pro CS6 and the glitch doesn't appear so it seems isolated to Vegas.
