@TLK82 without knowing what was the clip causing the problem, it is hard to give any possible help.

I have the exact same issue with crossfades since upgrading to Vegas 22 last week. Is there any resolution to this issue yet? I am on a desktop PC I built a couple of years ago for video editing using a Geforce RTX 3070. Again disabling this causes the green frames on the crossfades to go away but its going to take hours to render the full clip this way. It also only happens when rendering into a 4K output. If rendering to 1080P the issue is not apparent with GPU acceration enabled.

@crag364 if you uploaded a small sample of your problematic video to the cloud (Google Drive, etc) that can be downloaded and tested by others with similar PC builds (you failed to mention what CPU and how much RAM you are using), there might be a solution.

Suggestion, add to your Signature in your User Profile, you complete computer specs like mine below.

CPU is - 12th Gen Intel(R) Core(TM) i9-12900K   3.20 GHz with 32GB RAM

You can see the issue here between a cross-fade: https://www.dropbox.com/scl/fi/ykkxlylz4ska4dmdiukqm/test-2.mp4?rlkey=wyt2bkawcm87pair95p4f3x2g&st=4m9g0hjx&dl=0 However if I use a GL Transition it seems to be ok from some initial quick testing.

@crag364 seeing the issue is great. But having an unedited raw sample (it can be of anything) to try might possibly lead to a possible solution, or at least, an escalation of the problem to the Vegas developers.

Here is a file using the exact same settings I recently filmed on my GoPro - https://www.dropbox.com/scl/fi/99dbrlail4am5i3mhgtwi/GX010455.MP4?rlkey=c33jl7cx9mm4kizzv2wartrjp&st=3tbvwklc&dl=0

@crag364 Hi, I have a different PC on Windows 10 but just for the record I had no problem with your file in a 4k 120fps project (119.880p), I have a GoPro HERO11 Black & have very little if any problems playing or rendering these files.

I tried rendering 120p 4k with Magix HEVC & Voukoder without problems.

120p slows playback a little but picks up after a couple of plays, I didn't use proxies but i did try creating those at the end & of course the timeline Preview (Full) played fluidly.

There's a weirdness with the GPU decoding when cross fading, Encoding speed goes from 70 fps to 5 fps, the GPU decoder is at 100% Compare to Resolve where speeds goes from 220fps to 210fps during the crossfade and GPU decoding is at 87%

I thought they had fixed this already, but not seeing any problem with the encoding result

I just did some further testing with the clip I posted above. Thanks for the information @Gid as I wanted to figure out what was different.

I had no issues initially with it either, when adding crossfades. I have then re-added the FX I had in use on my previous project where I was seeing the issues and now I am seeing the same problem.

The FX I have in use on each clip are:

• AI Sharpen
• Colour Corrector (Secondary)
• Colour Balance
• Colour Grading

Removing each one individually and I cannot narrow it down. @Former user Yes you are correct the encoding speed dramatic reduces when cross-fading I am thinking with this reduction and the FX its to much for the GPU to handle, but never seen this issue on Vegas 19 I was using before I upgraded.

It would be good if others could test it to.

@crag364 what does your render settings look like?

I rendered using AMD VCE at 59.94fps and there were no issues at all with playing back the project.

Question, how did you get up there? :D

@Reyfox It was a good walk :-)

Here are my settings:

Thanks

@crag364 thanks for the render settings. I duplicated them outside of me having an AMD GPU. No issues at all during transitions and playback once rendered.

Thanks @Reyfox. It would be good if someone who has an Nvidia GPU could give it a try as I suspect that may be the issue.

@crag364 no problem! Also, include your GPU driver.

I have actually just updated it to the latest studio driver (I did have the game driver) but there is no difference, I still encounter the same problem. The Driver is now V566.36 Released: Tue Dec 10 2024.

@crag364, with my AMD GPU, no problems. @Gid and @RogerS both have Nvidia GPU's, hopefully they can give you some advice since they haven't experienced the issue themselves.

@crag364 Hi, I tried your clip with the fxs mentioned, I added the fxs & tweaked them just a little, sorry I didn't see that you'd suppled a project file but I got the same result with green frames at the crossfades anyway. I tried the orig in a 59.94 & 119.880 project, same result with both I got green frames in the render with Magix HEVC & Voukoder.,

Expanded track mode shows the green frame but it doesn't show when playing the timeline, playback was poor tho,

Rendering does this to my GPU.

A still of the rendered clip playing in a media player shows the green frame.

---------------------

I converted the orig with Shutter encoder, used Replace in Vegas - Project Media to swap the files, rendered & still got green frames on the transitions.

----------------------

prerendering fixed the playback but render still had green frames..

@Gid, I used AMD VCE to render the project.

@Gid Well thats good news, at least its not me going mad 😀. Thanks for the thorough test. I also do not see it at all in playback, only when it is rendering so it looks like we have the same problem.

@Former user Yes you are correct the encoding speed dramatic reduces when cross-fading I am thinking with this reduction and the FX its to much for the GPU to handle, but never seen this issue on Vegas 19 I was using before I upgraded.

@crag364 It's not your GPU, it's a Vegas limitation/bug. I can play a single clip at 240fps without frame drop, but when blending the 120fps file with it'self I get 5-7fps with 100% GPU decode even though Vegas is still only having to read 240fps. It's having an issue blending the frames from the new GPU decoder while it never had the problem with the old GPU decoder, VP20 will encode the blend with no slow down.

In VP20 it will blend at 75fps encode with 20% GPU decode, in VP22 it blends at 5-7fps with GPU decode of 100%

I get the green frames using your project file when encoding to Voukoder indicating the problem is not with the Vegas encoder.
