When I render 60p AVCHD video from my Sony CX700 to an NTSC MPEG-2 file (for playback on a DVD), Vegas randomly duplicates frames. This is 100% repeatable, and I have created a simple test case that anyone can use to reproduce the problem.
This is a devastating bug because there is no way around it.
I briefly returned to the forum a few weeks ago to help pinpoint the nested interlaced video bug. I am back one last time to report a much more troubling and very repeatable bug that potentially affects anyone who creates DVDs from their AVCHD footage.
I have confirmed this bug using Vegas 10.0e Build 737 32-bit running under Windows XP Pro. I do have Vegas 11 64-bit running under Windows 7 64-bit, but haven't tried to duplicate the problem on that version.
Here is a link to a sample clip, and a Vegas 10.0e VEG file that you can use to duplicate the bug:
MPEG-2 Render Bug Test Clip and VEG file
The AVCHD clip is directly from my Sony CX700 camcorder without any alteration or change whatsoever. Other clips also exhibited the problem.
All you have to do is load the project, and then render using the "DVD Architect NTSC Widescreen video stream" template. The only changes to that template is that I used 7,600,000 constant bitrate, and "best" for the quality. Here is a snapshot of my Render As template: [edit] Later versions of Vegas default to Upper Field first; I used Lower Field First.
If you put the rendered MPEG-2 onto the Vegas timeline, and match project properties to that clip, and then walk through one frame at a time, you should see many duplicated frames (i.e., no movement from one frame to the next). In my test, I get duplicated frames at frames 96 & 97; 108 & 109; 111&112; 126 & 127; 141 & 142, and probably many more.
I have owned every version of Vegas from 4 through 8, and also own 10.x, and have rendered many thousands of MPEG-2 files. I am quite certain this bug has never been there before.
Here's one more bit of information: I copied the events from the Vegas 10.0e timeline and was able to paste them into Vegas 8.0c. Much to my surprise (and relief) that worked, and I was quickly able to recreate all my work in 8.0c. Here's the important thing:
The result rendered perfectly to an MPEG-2 file, using the same settings shown above.
So, if anyone else can duplicate this, perhaps Sony will take a look at it. They certainly are not going to look at my technical support submission since it is clear that everyone in Sony tech support has permanently gone home. For instance, even though Sony acknowledged the nested interlaced bug here in this forum, I still have not received a reply from my tech support ticket which I submitted over six weeks ago.
Sony really should admit that they no longer provide any support whatsoever for this product, and drop the price down to the $40 level that zero support implies. It is unconscionable that they charge hundreds of dollars and then provide no support whatsoever. I certainly am not going to spend even the "early-bird" upgrade charge to purchase Vegas 12.
