Lag in Preview

zwilson wrote on 12/17/2021, 7:58 PM

I'm currently using the trial of Vegas Post 19 and I have a problem. I have a 1440p video that lags and stutters in the preview window when I scrub the playhead trough the clip in the timeline. However, in Premiere Pro 2022 there is no lag or stutter with this clip when I scrub using the playhead. I'm I missing a setting in Vegas that would fix this?

If you're running on default settings most likely the buggy Vegas GPU decoder. what cpu and GPU do you have?

You can try turning off the GPU decoder and do the same tests, you need a strong CPU that can take the extra load that your GPU decoder used to do. Report back if you see benefit or not. I am guessing this is NVENC encoded?

@Former user @zwilson Nope I don't think you're missing anything, I'd be interested in Vegas being better at this, I get stutter but not in the cheaper MEP Premium,

PS - I tried disabling Legacy AVC - no improvement,

I tried turning off GPU - no improvement.

If I actually grab hold of the cursor head so that it 'scrubs' through, I find it almost impossible to control, it jumps n stalls like it's on elastic. like dragging it through lumpy Porridge

This was one of my earlier complaints on my old PC i7-7700 CPU, 1660GTX SUPER 6GB GPU & 64GB RAM but Vegas wouldn't even play a clip with zero fx's at a decent preview quality.

@Former user if they could just 'drop' that MEP rendering engine into Vegas it would be such a superior product. Only problem I noticed was it's inability to read some Sony a73 422 color files, but still it did not crash or do anything weird just calmly displayed a message saying 'codec not supported'. There was another file type also 422 I think where it has to turn GPU processing off to support it, and as you say it's really great value for an OFX NLE editor

@Former user Yeah, Vegas needs pimping, even now with this machine, the slightest fx can send the fps from 29,97 fps into the 5s & 10s, but MEP will play a transition/fx fluidly 1st time pretty much.

I'm just trying to be patient, hopefully they will sort it out, i don't know enough about the programming but i suspect they're patching over patches on an antiquated system, maybe it's time to bin it n start afresh.

The cpu is an 11th Gen Core i9 11900K 3.50GHz and the GPU is NVIDIA 3060 12GB. I've tried it without gpu acceleration and it performs the same.

I put 2 clips in MEP Premium, I cut & threw them around a bit, added crossfades & random transitions inc some of the worst like a shuffle n flying card flip thingy, MEP plays it 90% perfectly without a hiccup, I think this is partly why people get annoyed when they move over to Vegas, because i know even n my machine this wouldn't be able to be recreated with such fluidity in the Vegas timeline, so with a lot of people have standard - good machines Vegas will be a let down when it won't do simple tasks without stuttering as the OP has stated.

I haven't altered this, it's in real time & the preview on a 34" 4k monitor is as clear as Good (Full) in Vegas.

Just to confirm when you say you disabled GPU acceleration did you actually disable the GPU decoder, because that was my suggestion. We could be talking about the same thing just you are using a different term that's still technically correct and how it's termed on Premiere

If you did do this and still horrible scrubbing, the last resort if you are using NVENC and are screen capping (you did not confirm when I asked before) you can set max b-frames to 1in OBS, if that's what you're using, and also keep decoder turned off. This is not a perfect situation but will make scrubbing and playback smoother.

This seems amazing to VP users, but really it's not, similar performance on all the big NLE's, but for a $75 NLE MEP2022 punches above it's weight

Migrating The Infusion Engine 3 to Vegas? This can be frowned upon by the MEP/VPX team.

I"m beginning to understand the problem, both Magix products, but resources and IP are not shared between the different divisions

@Former user Yep that's what i turned off, i've tried a few settings over time tho, nothing makes the scrubbing perfectly smooth, it's ok just a little jumpy, a 4k clip plays ok at Good (Full) but like i say nothing as smooth as MEP like in my vid above,

I'll wait, Vegas has to improve or will get left behind,

That's the problem, it's already happened, 'Sony Vegas' was a household name on youtube, for a time saying "Sony Vegas" instead of NLE was the Kleenex of tissues, people who never edited would keep hearing that term  , word of mouth promoted the product. Magix/Vegas needed to improve the render engine and gpu decoder problem years ago, release of VP15 would have been perfect, so that the so4 GPU decoder and it's problems never existed, now I fear they've lost too much of the market for it to be considered sensible to invest a large amount of time and money into this.

 I don't think what we would like is even feasible now, they went a different route with patching and plugins of original Sony Vegas software, the business model will continue as it has, adding extra features, and trying to keep the ui look modern.A perfect replacement Vegas replacement doesn't exist yet.

Vegas is never gonna get left behind..... Been hearing this trash talk from 2003 till this very date... And is Vegas gone? NO!, its still here. Far better and more advanced than ever before.... Point me to the perfect NLE that has no flaws, drawbacks nor weaknesses!

Vegas Pro has its weaknesses, but it's no slouch or a second rate NLE. It has its foothold. All it's flaws and drawbacks are being actively pursued daily by the Vegas team to make better and improve. But unfortunately their hard work is never quite enough or the right direction for some..... But even then, no matter how much Vegas improves or even surpasses features in other competitive NLE's, the constant trash talk about it and the development team will never cease anyway.

@Steve_Rhoden I was just looking at this forum from 2017, and that's when you joined, a lot of big name users from that time have left since, but also from that same year someone was complaining about no NVENC support asking how hard is that, please make that happen. VegasPro's biggest supporters just made excuses for why there was no NVENC encoding, saying it wasn't necessary, it's not useful, it's low quality, just giving reasons for why it was ok not for Vegas to have this feature.

Later that year Vegas introduce NVENC encoding in VP15. Maybe that guy complaining helped make NVENC happen. Few would say hardware encoding is of no use today, but because it had not yet made it to Vegas at the time there were people prepared to argue it wasn't needed.

Remember what this thread is about, a user with a high end computer can't play 1440P video smoothly, and he makes a comparison to other editors that can. It is identical situation for me, to complain about stability and smooth playback issues when we know it's possible on another is not unreasonable. That lead on to why this is likely the case today even with VP19. We know those guys arguing against NVENC were most likely just trying to be supportive of Vegas, maybe this is similar

@Steve_Rhoden This isn't trash talk, it's sharing & discussing observations, this is feedback & voices of hopes & wishes, isn't that what a forum is for,

Former user wrote on 12/19/2021, 5:25 PM

Plenty of trash spoken to the screen tonight tho after a dozen crashes, 1 fx applied & tried on many various settings

I think what @Steve_Rhoden is saying is that there will always be a complaint, no matter how much the software improves. There will always be comparisons to other software and their features that aren't a part of this software. For sure there are advantages to using other software. I have several that I will use for certain projects. But again for "me", I am happy with the progress Vegas is making and for what I do, it works. With every editor, there are short comings.

There is very little positive comments given on improvements. Are they worth the upgrade? Only the user can decide.

How long have MEP users were stuck with a slow rendering product? Go to any PCMag review where they time the same project on the NLE's they review, and almost always, MEP was last ..... way last. For years.... now, things have improved. I am sure the VEGAS developing team are well aware of the the deficiencies of the software.

As for people that have left the "fold", it happens with every editing software out there. People leave for various reasons to another product, and there is no one product that is the "bees knees" for everyone.

This is from PCMag with MEP render speeds from 11/20/2020. It hasn't been tested recently by PCMag. But consider how long things took, and this was for years....

@Reyfox Yep those render times of MEP in the past were part of the reason i swapped to Vegas, that & i wanted more control & be able to add plugins, which Vegas does, It was an MEP update i got a short while ago that surprised me, Like i say in this comment 'I know MEP Premium can't do the things Vegas can do & i'll continue using Vegas .. I'm just sharing & the grass is always greener 👍'

@Former user the grass is always greener, on some parts, on others, there is no grass. It seems that there is no "perfect" NLE, just ones we work with and work around.

For me, rendering is only part of the equation. I have the top exporter in that image above. Do I use it? I bought it because it was "cheap", and had some nice plugins included. I have yet to edit a complete single project on it. It's not hard to use either. Just not the way I like to edit. Preferences and needs.

Every single project I started with VP, I've been able to complete with very little "fuss" on my part. My machine is no where near the beast that yours is. But it gets the job done. That's all I ask.

I do have an older version of Video Pro X, and have MEP Premium 2015 and 16. I was always intrigued with the software, and VPX was an easy way to get into higher end editing at the time when Vegas and others were higher priced. But for me, after buying Vegas 14 Humble Bundle, in 2 weeks I was hooked. Been here ever since.
