Vegas 13 MPEG-2 PAL DVD Rendering issue

Craggy wrote on 9/26/2014, 6:14 AM

ARGH!

I am going off my head, recently upgraded from movie studio to vegas pro and edited a full wedding in vegas pro and now, when I render it to MPEG-2 for DVD, the footage glitches and jumps at pure random moments throughout the video.

About 95% of the video is all fine but there are split second sections where the video jumps or glitches when I pay it back after it's rendered.

Rendering the full thing in HD shows no problems, only when rendering down to MPEG-2 for PAL DVD. I should also add that I use the same template I used in Sony Movie Studio, which worked flawlessly and never had any these issues.

So annoyed right now as I cannot find a solution or fix as to why the footage is glitching during the render. The video plays back fine in the preview window, its only after I render it, it seems to go wonky.

Anyone else experienced this?

I read the other thread about the MPEG2 rendering issue. I was thinking of getting VP13 on the latest discount offer until this. I render both NTSC and PAL DVDs each week on the scuba boat. Never saw this in VP10, 11, or 12.

So the jumpy bits, is there any track motion, pan crop, or other FX on them? I've seen the jumpy behavior on those Digital Juice quick projects that you can buy for $10. They come off in NTSC 29.97 and if you render them to anything else you need to fuss with the pan crops, etc. otherwise you get jumpy bits here and there.

That's why I asked about motion type FX in your footage. Maybe the template looks like it's fine but under the hood there is a mismatch somewhere? Grasping at straws here.

Hi I upgraded because of the discount, regretting editing a full wedding in it now as there is currently no fix! The settings are all matched as they would normally be when I used movie studio, all settings under PAL 25fps, very minimum effects, wee touch of colour grading, nothing heavy.

I removed the effects to see if that solved the problem but it doesn't, just so strange!

I had problems with glitchy MPEG-2 output with V13. I found that turning off GPU in the Options menu fixed the problem. I then contacted tech support and they recommended that I update my nVidia GeForce 9800GT driver to the latest version. Based on advice from OldSmoke in this forum, I upgraded to a driver that was much newer than what I was using, but was not quite the latest driver.

Sony tech support also recommended that I update to the latest version of V13. I did that as well. I then re-rendered, with the GPU on, and this time I got a clean render.

So, try turning off the GPU. That is much easier than taking the time to upgrade the driver, and the GPU didn't make any measurable difference in MPEG-2 rendering time on my computer.

thanks john, have updated my driver, still not fixing it, tried rendering with gpu on and off, no fix and I have the latest version of vegas only bought it 2 weeks ago.

awaiting Sony's update...

OK, so it's not a GPU issue.

Here are some other ideas:

1. If you can, post a screen shot of the "Video" tab from the MPEG-2 Render As dialog. Also, if you can, post a screen shot of your project properties.

2. If you can't post those screen shots, check your settings against these dialogs:

PAL MPEG-2 render settings. Make sure field order is upper field first (assuming your source media is HD and therefore upper field first).

Project Settings. Make sure Deinterlace is NOT set to "none," and "Adjust source media ..." is unchecked.

3. If you can, go to the timeline a little before one of the sections where the video glitches, and then create a loop section 4-5 seconds before and after the glitch. Then, render just this loop and upload it to MediaFire, DropBox, or some other upload site, and post the link here so we can look at it. Hopefully the small section will show the same glitch. If the problem isn't a bug in Vegas, but instead is some sort of setting that is wrong, it is often easy to see the problem when we get a sample.

4. If you have MediaInfo, drop your original media on that, and post the results. You didn't mention the nature of your source media.

Now that you have ruled out the GPU, if I were to take a wild guess about what is causing the problem, especially since you didn't have a problem with Movie Studio, I'd say it is that "Adjust source media ..." setting in the Project Properties. I don't know if that affects renders, but every automatic adjustment that Sony has added to renders (like the ones available in the AVC renders) really screws up the results. Also, if any of the Render As settings have been changed from the defaults, other than the ones I show with my red arrows above, that might cause a problem. Check your settings against what I posted.

Thanks for taking the time to post all of this info John, the footage comes from canon DSLRs shooting HD 25fps, I'll try the adjust settings box because that is ticked at the moment, not sure how to add screen grabs but to describe it, when the glitch happens its for half a second and it jumps or flickers between the current shot and another shot from the timeline

I'm PAL user, from Indonesia... But I never had any issue on this....

If you need to post the image, upload them to any image-host server (like Dropbox), and use tag as described here

----------
According to John Meyer's post:

The Average bitrate should not exceeding 6,000,000.

Wow, my Field order has always been set 'Lower' all these days..., well, it was a continuing setting since the DV days..., and never had any flicker issues.

Will changing to 'Upper' give better result from HD (AVCHD) sources?

I am having the same problem.
my footage:
1920x1080 24p
I have tried everything, but every time i try to render my project to a MPEG-2 DVD format I get these glitches randomly throughout the rendered video. I don't know how to proceed.

@Craggy

Do you see the glitches when you play it back on your PC with WMP or in the final DVD when you watch on your TV played from a DVD or BD player?

Preston123 wrote on 1/21/2015, 1:43 PM

I see it when I play it back on WMP.

Preston123 wrote on 1/21/2015, 1:45 PM

I also have taken the rendered file and placed it in a Vegas Pro 13 timeline and see the glitch there also.

I would still try and burn a DVD, preferable a DVD-RW and see if the problem is really in the file or a playback problem. I do get on off even "hand ups" when playback MPEG-2 files via WMP but the file is actually fine when I put it on a DVD, it never happens with BD material.
Just make a simple project with just one media and burn it onto a DVD-RW.

Also check your project for Quantize to frames and any gaps. I use Vegasaur which has a nice audit tool that will look even for the slightest miss alignment of video and audio. I ma sure there are other tools that can do the same.
