Vegas Pro 13 MPEG2 Render Bug

MarkHolmes wrote on 5/31/2014, 2:27 PM

Hey, just when I thought Vegas 13 was bulletproof, I've run across a glitch that forced me to copy and paste an entire project back into Vegas 10 for render.
I have a simple timeline (2 Panasonic GH3 AVCHD clips) that totals 2 hours, simple titles. Everything was fine til I went to render an MPEG2 for DVD (client still insists on a DVD and HD delivery) and the render (not the original clips and not showing on the timeline) shows a weird one-frame glitch - every 20-30 seconds for the entire two-hour render.
Anyone else experience this?
Here's one example of it:

Another possibility. You might have quantize to frames turned off which is allowing your edits to end up on non-frame borders. When you render these, they will get rounded to a border (sometimes blank, sometimes overlapping). This might cause what you describe.

Thanks for your help Dave, quantize to frames was off, I seem to be having a bit more success rendering into small 2-3 minute clips... very odd but if I need to divide up the footage just so I can render it just now that may be what I need to do.

Will update if I get a fix or solution from Sony

IF quantize to frames was off, you will have some events ending in between frames. You need to go through and check each one and adjust. You can also download Gary James' Timeline Tools and it has a script that will do that for you.

Turning it On doesn't fix the errors, it just prevents them.

I checked through the footage, I always make sure the clips are snapped onto each other if they aren't faded over so there are no gaps, think I had turned this off because I was having a hard time lining up audio tracks with it on....

Ill need to revert back to movie studio until I know exactly why this is happening

In addition to having the clips snap to each other, they must also line up on the frame boundaries of the timeline. You can have them snapped, but if the frame boundaries are off (Quantize turned off) you can still get errors in your renderings. You should NEVER turn off Quantize when editing your video.

You can turn it off when editing audio only.

Thanks Dave appreciate all your advice, why would it still render fine in HD tho....

Craggy, some things to try:

1. Make sure your project properties are matched to your media properties.

2. Check "Do not quantize to frames for audio-only edits" in your Editing preferences. Then there's no need to turn off quantize.

3. Turn on this setting in your internal preferences. It highlights unquantized boundaries in red. Hold <SHIFT> while opening "Options > Preferences" to get the goodies on the "Internal" tab. But note that the official line is that you shouldn't touch that stuff. After doing this make sure the start of every video event is not highlighted in red.

4. File > Project Properties > Video > Full-resolution rendering quality = "Best"

5. File > Project Properties > Video > Deinterlace Method" = "Interpolate"

6. You might try to disable resampling by right clicking on the video events > Switches > Disable Resample, or use a script.

"[I]Thanks john but that doesn't appear under MPEG-2 PAL DVD render...[/I]"

Not enough coffee when I posted. There is no GPU assist for the Mainconcept DVD MPEG-2 render templates.
