Bad Pixelation happening in Vegas Pro 22 (build 194)

Debbie-Whitmer wrote on 11/3/2024, 2:36 AM

11-3-2024 - I need help please! I’m having a problem with Vegas Pro 22 (build 194) I just purchased yesterday; I installed Vegas Pro 22 and the "Vegas Deep Learning Models" that it came with. I’m currently using Vegas Pro 20 (build 411) and there is absolutely nothing wrong with Vegas Pro 20 and it works beautifully. I have both Windows 10 Pro and 11 Pro but I’m using Windows 10 Pro right now. (As a side note, I do post production for a radio station that streams LIVE for its broadcast and the broadcast can be between 1 to 2 hours long.) But now, in using Vegas Pro 22 (build 194), WHILE EDITING, Vegas Pro 22 intermittently causes the man’s face who does the broadcast to be pixelated very badly and then goes back to normal. And then, sometimes right after that, I will get a flash of a solid black screen and then goes back to normal again. And sometimes that black screen will flicker. And after I render it to test it out, the pixelation and black screen and some flickering remains. The raw video I’m using for post production after I downloaded it from LIVE streaming is perfect and there’s nothing wrong with it so I know that Vegas Pro 22 is causing all this pixelation/black screen situation. This is totally unacceptable. Vegas Pro 22 does this pixelation in its default settings. I’ve tested and tested and even used my Vegas Pro 20 settings and put them into my Vegas Pro 22 settings (really not that many changes) and nothing works for me. My computer hardware and Operating System (OS) is in my profile. I do have two (2) snapshots displaying this problem and I can upload them here if I can find where to do that. If you know what’s causing all of these aforementioned problems or what settings I need to change to stop all of pixelation and black screen and flickering from happening, PLEASE let me know ASAP. If I cannot get this fixed, I’m going to have to return Vegas Pro 22 for a refund. Thank you so much for your immediate attention. I look forward to your replies.

Sincerely,
Debbie Whitmer

@set- Hi there! I've just tested a little thus far but before, VegasPro 22 (build 194) used to render slower than Vegas Pro 20 (build 411). But before rendering to Vegas Pro 22 (build 239), I went to Options>Preferences>File I/O and unchecked "Enable legacy AVC decoding" because that was a temporary work around for me before the update. After the update to Vegas Pro (build 239), it now renders as fast as VegasPro 20! I rendered a 49 minutes, 34 seconds Radio Broadcast that I do post production on and it rendered in 15 minutes. That's a good thing! 👍

@EricLNZ - Thank you so much for posting this information! 👍

Thank you for the news. I haven't updated to the new build yet, but in reading the change log, the only thing I see that mentions AVC (which I presume is the same as AVCHD?) footage is:

The Pixel Aspect Ratio is now properly applied for all AVC media

Is that the fix for the issue @Debbie-Whitmer and I were having where the video would distort in random places?

Hello @MikeLV and eveyone. I hope you are all having a good day! I did some further testing regarding this pixelation issue. Just letting you all know in using Vegas Pro 22 (build 239) I did NOT notice any pixelation YET while editing and after rendering the same video that I originally posted under this heading having pixelation problems. However, in using all the default settings with Vegas Pro 22 (Build 239), I DID have some jerking, flickering and some black screens in various places and then it would come back to normal again which, of course, is unacceptable. However, to overcome this issue, I had to go to Options>Preferences>File I/O and I MUST check mark “Enable legacy AVC coding.” Both “Enable legacy AVC decoding” -AND- “Enable experimental HEVC decoding” are now both check marked on this page.

Since I can overcome this jerking,flickering and black screen obstacles with the aforementioned remedy, I will do that as it gives me a finished rendered video without errors.

@Debbie-Whitmer, I don't believe that the HEVC setting should have any effect on the previous issue as that's an entirely different format than AVCHD. But from what you're describing it sounds like the previous problem still exists, but it has morphed into some other manifestation (jerking, flickering and black screens). Given your comments, would you recommend against updating to Build 239 and continue to use the legacy AVC option? Or is it still a good idea to update?

@MikeLV Yes, you are correct; I was just letting everyone know that both HEVC and Legacy AVC coding were both check marked on the File I/O page.

Regarding your question, I think that if more people report having the "jerking, flickering and black screens" issues with the default settings, then Vegas should find a solution for that as that would permanently be inside of a person's video after using Vegas Pro 22 which is unacceptable and unprofessional especially if a company is paying you to do their videos. However, for ME, by going to the "Options>Preferences>File I/O tab" (which was suggested I do this a long time ago as a temporary fix for the pixelation issue) and check marking the "Enable legacy AVC coding", it is a solution which solved all the aforementioned issues.

I was so glad that Vegas finally released Vegas Pro 22 build 239 and while reading the long list of bug fixes, that is always a good thing as a whole but invariably other issues come up. As the old saying goes, "It's always something." LOL! But all in all, I really like Vegas and have been using it since Vegas 8 I think, it's user friendly for the most part and brilliantly made. And everyone has always been so kind and helpful when a problem arises and I have had all my issues that I was having fixed throughout the years.

@Debbie-Whitmer @set @RogerS So I went ahead and updated, disabled the legacy AVC option, opened one of my videos and started clicking around the timeline. Sure enough the image distortion is still happening as shown by this distorted face. It seems the issue hasn't been addressed in Build 239.

@MikeLV - Oh no! Oh my! That's the pixelated nightmare picture that no one wants to see! Then this needs to be fixed ASAP! In the interim, please try to enable legacy AVC to see if that helps. It did for me.

@MikeLV - In using the default settings in Vegas Pro 22 (Build 239) and NOT having legacy AVC check marked, I started tapping around in the video I was testing with and, indeed, I got pixelation as well as you can see and MORE black screens. This needs to be fixed ASAP.

I guess we can just start a facial disfigured club! 😂 Yeah, the legacy AVC setting does fix it as a workaround, although, I don't know if that setting causes problems elsewhere or not; haven't noticed any.

LOL! to the "facial disfigure club!" I haven't noticed any problems using the legacy AVC setting. But thank you for letting me know that the legacy AVC setting worked for you.

I'm using the same version and build and am also experiencing the pixelating issue at random points in the video at the OP reported. My footage is the same footage I've been using for years, AVCHD from my Canon XA10. The corruption is not in the original footage, it's only seen on the Vegas timeline, and it carries over to the final render. Is there any update on a fix for this issue? I skimmed through the thread and it appears there was a workaround which I guess I'll have to try if there isn't a proper fix?

Update: I checked "Enable Legacy AVC Decoding" and it removed the pixelation I was observing in one spot, but not others, i.e. that option doesn't work around the problem after all.

2nd Update: After reading some more in another thread, I also turned off hardware decoding altogether in that same preference window and it appears to get rid of the pixelation issue from what I can see. I hope there will be a fix for this.....

I experienced the same with my XA11 footage today, and progressed the same as you -- first enabling Legacy, then disabling hardware decoding all together to get it working in timeline and render.
