Vegas 21 fails to correctly recognize GPU, no preview acceleration
@Howard-Vigorita On the left of video is Voukoder Prores444, right is Vegas ProresXQ. It's cropped 2x Are you able to visually see the huge difference in PSNR values, what would cause that? Obviously this is 420 8bit Magix server transcode, but because it's low motion and not overly detailed thought it could still have some use

VP 21-187 PIP GPU crash
The problem is your 2GB of video ram. What you could do is work in 1920x1080, encode in 1080P, and alter the meta data so that players and Youtube etc will see it as portrait

VP 21-187 PIP GPU crash
What I mean is because you never disclosed you have the 2Gb model, there was an assumption made you had the 4GB card, and people were curious as to why your had ram errors, and there was a potential fix, but as you have 2GB model there may be no fix nor any bug to fix. Task manager shows me that Vram usage, although I do not play the file, and only a single frame is ever viewed maybe there is background Vram caching of the video. Still not sure exactly how VP21 works

I've asked you previously is your 1050 the 2GB or 4GB version, but you didn't bother replying. RogerS has the 4GB and has no problems, so if you have the 2GB there may be no reason to expect anything is wrong, you just don't have enough Vram. For me 1920x1080 = 3.3GB Vram on load displaying 1 frame, but 1080x1920 = 3.5GB

Text-Based Editing?
@fr0sty I didn't think it would be due to a technical limitation but maybe a preferred business model. Adobe used to be cloud based, they moved to local AI models and then text based editing, Resolve uses local models too, maybe Vegas is next

Vegas 21 fails to correctly recognize GPU, no preview acceleration
@Howard-Vigorita Fair enough Howard. On the subject of Vegas's compressed stream to Voukoder and the limitations in quality that may result. I did see a noticeable difference in 444 UT from vegas to 444 UT in voukoder compared to Vegas, but I still question if that's really a problem, it should be known about for sure, but for most they would hope for no quality difference at 420 8/10bit or 422 10/12 bit using 32FPU. When I redo my test if the results appear similar to each other between Vegas and Voukoder I"ll then do similar to what you do, crop an area of the video and analyze it visually. I noticed the 4K VMAF is giving me 100% quite often in these UT video encoding tests, so not sure I trust it, therefore I was using the normal VMAF model for 4K, which gives lower scores which seems more realistic but maybe I shouldn't be doing that either.

@Gid I noticed that the old SO4 decoder used all my CPU cores to render the frames to the encoder which may be why you see no difference. With some HEVC formats SO4 was single threaded but not for Samsung HEVC

Text-Based Editing?
I use it all the time, Can be amazingly time efficient editing long videos. Problem is the way Vegas does their subtitles in the cloud rather than locally. Maybe not a problem for them, it's a way they shift people from Perpetual versions to subscription which they prefer. So if they do bring in text based editing it'll probably be as another carrot on a stick to make you change to subscription

It even holds onto it's Vram cache after opening another project. I think It would be preferable to remove the cache when opening new projects

@RogerS Yeah I think so, maybe without even playing it . One of the new Vegas staff mentioned the more Vram you have the more is used to cache files, as the file was only 6 seconds it was very easy to cache it entirely

One note is that the 8K automatically creates a proxy file so cancel/delete it to see what it's really like. Edit: here it is playing with the non SO4 decoder I started a new project, confirmed auto proxy was not turned on, watched GPU decoder as I brought in the file don't see any decoding, none on playback. I check again, it is as you say the new Vegas HEVC GPU decoder in use, and yet I can blend 4 tracks at once effortlessly. This should not be possible. I'll check my 8KS23U camera footage, see if I get the same results

Vegas 21 fails to correctly recognize GPU, no preview acceleration
@Adis-a @Howard-Vigorita I converted some digital raw to 4K ProRes 4444 XQ, encoded to 4K 422 UT lossless video, this is the result. So Vegas wins here, but it's bitrate is also higher. Just not seeing the low quality results that Howard alleges. Keep in mind that if you use ProRes as a reference, that it has allot of synthetic content that may or may not be representative of modern 4k and larger sensors which only capture 4:2:0 color data. Dear God you're still saying that. Whenever you bring that up on this board everyone disagree's with you, I link you to a Hollywood colorist who explains why that's not true, but you don't believe him either. That's why I need proof of what you say, because you stubbornly hold on to false beliefs. EDIT: I messed up here, I forgot to use 32bit FPU, used the default 8bit, Howard's main criticism is not seeing an increase in quality with 32bit, I"ll have to test that again

I can't quite work out what's going on with this file. It's behaving as if it's fully cached, and yet I never see any GPU decoder when loading the file and first playing, and there is no decoder activity here, nor is there much CPU activity. I've conformed the Gid sample file to 120fps, it's being played back at BEST/FULL, get up to 100fps, and playback doesn't degrade to unusable when blended. None of this should be true for the new decoder at least not yet, need to be bug fixed EDIT: It's using the old HEVC GPU decoder SO4, that still doesn't explain why it's playing so well and without GPU decoder.

Vegas 21 fails to correctly recognize GPU, no preview acceleration
@Adis-a It means that when I run an objective quality analysis comparing input to output, that little improvement results. I believe it's a general issue with all 3rd party Vegas render plugins resulting from the limited bandwidth feed made available to them by Vegas. @Howard-Vigorita Hm...don't know how to interpret "little improvement results", so I'll be more specific. Let's say I have a ProRes 4444 XQ as input quality, does Voukoder maintain said quality when rendering to ProRes 4444 XQ if in 32-bit mode? @Adis-a It's more complex then that because Voukoder's prores isn't real prores. It's why I had to encode to UT 'lossless' video, To test Howard's claims about a low quality/compressed data stream going to voukoder the limitation can't be the encoding codec. I found Voukoder's prores422 was inferior to Vegas's real Prores422 Maybe something like that is how Howard got things wrong or maybe he's still right, but in what situation? I"ll convert some Cinema Raw to ProRes 4444 XQ and encode to UT video again and see if there's any difference. Also maybe he see's the lower quality at 4K, while i'm testing at 1080P, we don't know what Howard is doing.

What does it mean, Voukoder not benefiting from 32-bit mode in Vegas? @Adis-a It means that when I run an objective quality analysis comparing input to output, that little improvement results. I believe it's a general issue with all 3rd party Vegas render plugins resulting from the limited bandwidth feed made available to them by Vegas. @Howard-Vigorita Can you show me your supporting evidence, I don't see that with using a Prores422 sample with high motion encoding to UT lossless video at both 420 and 422 color. It appears Voukoder has the highest quality. I do see the obvious problem that Voukoder's 422 UT is a higher bitrate, but when comparing the 420 encodes they're about the same, so lets say they're the same. That's quite different to what you're saying

I used some different software to load it's LLM's so that I only have 4GB Vram left, at 1080P everything still worked fine. I changed project to 4K, and Vram started swapping out to shared gpu memory (system ram), it ran appallingly but no memory errors.

No crash, I decided to load up the vram with external AI models, working on the idea it could be due to your limited Vram, it's either 2GB or 4GB isn't it? For some reason whenever I loaded up Vegas Vram use would go down so I was never able to max out the Vram and test that.

Vegas 21 fails to correctly recognize GPU, no preview acceleration
What I found generally is that final render quality is the most influenced by decoding quality which impacts Hevc much more than Avc. And that Intel hevc decoding is the highest quality. The next biggest influence that affects ultimate render quality is the data-chain, with 32-bit float better than 8-bit. Hardware decoding dramatically increases performance but often yields lower quality.. @Howard-Vigorita Is the low quality hardware decoding a Vegas problem or when you test outside of Vegas you see the same? With the new render engine it will default to 32bitFP like every other modern NLE and that will be a great day because we won't have to make the decision between highest quality but slow, or good performance but lower quality. The quality/performance trade-off between hardware and software rendering is larger but less significant than decoding considerations and seems to be less consequential for 4k hevc 10-bit renders... I often do my test screenings with Qsv and switch to MainConcept for delivery but I really don't actually see the difference anymore, so it's more of a habit now than anything else. I've asked many large youtubers hardware or software encoding? All the ones that upload at 4K use hardware encoding, there was a time they would bother with thread rippers etc for maximum theoretical quality, but not now. Linus Tech tips might be a holdout, and still use software encoding, but it's probably just because they can with so much power the performance difference isn't so much. Regarding Voukoder, it's severely constrained by the Vegas data-chain which is such a shame... does not seem to benefit at all from 32-bit mode in Vegas Can that be seen with normal sort of encoding to 8bit or 10bit 420 or are you speaking more of theoretical limitations such as encoding 444 12bit etc.I think you do have the studio version of Resolve, do you see the same problems with voukoder?

The fault is identical to VP20 and most likely all Vegas's since hardware encoding was introduced. It's very disappointing to read that this is still a problem. it's not exactly the problem I was describing - but I saw this one as well. This I think it one of the more major problems, because even with VP21b187 people are getting video frames shifted from one section of the timeline to another and you can see that here. Frame 0 - 59 Looks fine.Frame 60 is a duplicate of frame 0frame 61 - 70 are duplicates of frame 0 however they have mild artifactsframe 71 - 118 are correctly positioned frames but major artifacts. I noticed from when I first started reading this forum, their unusual hatred of hardware encoding, with stern beratings of people that dared use it over software encoding. The advice being it's only for rush's and if you respect your work final encode must not use hardware encoding. I thought that was a bit extreme, but actually they were right all along, BUT NOT about hardware encoding, the problem was and still is with Vegas's implementation of it. I just now ran a test on Vokoder - didn't look for the rendering problem yet, but it runs consistently without the bursts, and it's faster: the render took 58 min compared with 1 hour and 16 minutes in magix AVC mp4. I think it's every 60 frames it bursts? Something like that, and Vegas has to pause rendering for that to happen. I see about a 10% difference in times between MagixAVC/NVENC and NVENC in Voukoder- do make sure the settings are reasonably matched @RogerS How much faster voukoder is depends on resolution, you'll have different speed increases depending on if it's 4K,1440P,1080P,720P

Vegas 21 fails to correctly recognize GPU, no preview acceleration
Actually that reminds me of another issue with GPU acceleration - in rendering. Several issues in fact. 1. Using NVENC (with Magix AVC MP4, 4k, on Vegas Pro 18) sometimes leads to strange flashing results in the rendered file: I rendered a 90min file, and in two places where I inserted an image for a few seconds over the main clip, the image "flashed" for several seconds until a scene change. This problem is intermittent, does not appear in every project, and I could find no logic that would help reproduce it. It just sometimes happens with NVENC, and never with the CPU. It happened with several single & multiple GPU installed: GTX 1050, 1660, RTX 3060, 3060ti. Not tested on my 4060ti yet. It's a Magix AVC/HEVC problem, it seems easier to trigger with Magix HEVC NVENC, this is 4K 23.976fps VBR average 50mbit, maximum 135mbit. It's fine without the cat, but with added cat.... The fault is identical to VP20 and most likely all Vegas's since hardware encoding was introduced.

@VEGASMichael So far Vegas doesn't seem to be interfering with other high Vram software I've been using at the same time, and I"m not seeing high shared GPU memory use and the resulting slowdown
