Vegas 16 Preview Problems - Rendered Video different

kleefly wrote on 5/15/2021, 3:00 PM

I've been using Sony Vegas 13 for a really long time (it's always been really stable for me, so I just never wanted to upgrade), and seen Vegas 16 was on sale on Humble Bundle so decided to give a newer version a chance. Scoured the internet, couldn't really find too much about my specific issues.

I started my first project with this program, spent about an hour cutting and arranging my clips, everything in preview looked good on various preview settings, from draft all the way to good, all the clips were perfectly in place then I saved and quit. Today, after opening my project I notice all of the clips were all 3 seconds out of time. Best is the only preview option that is showing me my original footage time, but I can't use best to preview all of my video, and prefer to use preview, good or draft if it's layer heavy. If I render it looks like the preview of the "Best".

I have never had this issue with Sony Vegas 13 and I've used a plethora of different video file types in the same project. This one... so far I'm using one Mp4. What is going on here? If anyone can help me out I'd be much appreciative. Upon further inspection I tried using M4Vs and I'm not getting this issue.. it's only seeming to be the Mp4's I have.

I'm running a
Vegas 16 Build 424
Windows 10
AMD Ryzen 5900X
32GB Ram
GeForce RTX 2070 Super

Is it really out of time or is preview just lagging (see the framerate under the preview window). You can temporarily bypass Fx to see it at full speed.

If that's not the issue, what are the files you are having trouble with? mp4 is just a container, we need to know what is in it.

Copy and paste from MediaInfo: https://mediaarea.net/en/MediaInfo

Also try upgrading your NVIDIA drivers to the latest Studio driver (not the standard gaming one).

Thanks for the reply. I've actually fixed the problem last night before bed. Must have been a bug of some sort with the preview. I renamed the folder that contained the compoundplug.dll that the video was using it's plugin and for some strange reason it's working fine now. I got this tip from someone who was having Green screen issues, and just decided to try it, even though I wasn't having that specific issue. Not going to lie, I'm completely perplexed as to why that worked.

But yes, it was really out of time, the previews were not lagging according to the frames. Draft, Preview, Good preview qualities were all 3-4 seconds out of time than the Best quality preview. What was being rendered is what I see in the "Best" quality preview.

I think you may cause other problems for yourself if you hide core program features from Vegas.

Compoundplug is required to decode certain formats and optional for others (it's been partially replaced). If you have legacy AVC enabled uncheck that and it should use so4compound instead of compound.

To figure out what media wasn't playing in sync we need MediaInfo. 3-4 seconds out of time is a massive difference.

I think so too, which is why I'm still trying to find another way around it. Turns out it was actually the so4compound folder I renamed not the compoundplug folder. I was mistaken. I changed the name back just now, and my clips are once again out of time. So I'm assuming renaming it was forcing it to use compoundplug instead?

I'm not going to lie to you, I have no idea where to find the Legacy AVC option you are talking about. I googled it and can't for the life of me see it.

This is a screen cap of 2 files that I was having the same issue with. They are both .mp4 and this is the information mediainfo gave me.

I've just found the files I was using was using So4compoundplug, so I disabled it in Internal part of preferences. The files are using compoundplug now and it's better. I'm hoping disabling it won't cause me issues.

You really can't hide files and expect Vegas to work.

For Media Info, here are instructions: https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

There's a lot more info available in Media Info that's important to include.

Was this file from a phone? GoPro? Drone?

For turning off So4compound without hiding files hold shift and then enter preferences. You'll see an internal tab. There you can set values from true to false. Try Enable So4 Compound reader for AVC first (set to false), restart and see if that helps.

Here's my VP 16:

While it may benefit stability, it also means the GPU isn't doing decoding anymore which might slow things down (though that's no different than how VP 13 worked). If we can figure out which media is giving it trouble you can just transcode that before bringing into Vegas and get both correct file decoding and speed.

If it still doesn't work set the next one to false ("enable hardware decoding for So4 reader")

Are you using the NVIDIA Studio Driver? A new version came out recently.
