In think it’s your workflow. If I interpret what i see in the video then it seems you like to move event darling on the timeline or even delete them while playback is on? If so, that is not a good idea and it does make Vegas unstable.

@OldSmoke Yeah, that’ll put stress on everything. Now we know that Project match Media, I’d go with a DI.

please take a look at this:

Vegas is likely to crash if you move or trim clips during playback. Pretty much a known flaw.

@OldSmoke

Any preliminary observations about preview performance improvements with VCE in Vegas 15?

VCE like NVENC does not improve preview performance, it is primarily for rendering.

NVENC is still a mess - at least for me. I had to revert to the older Mainconcept encoder as using NVENC causes random white flashing of some of my footage. I've attached a sample without audio that shows what I'm referring to.

I will admit - this update to Vegas 15 seems about as solid as I've EVER experienced. Still laggy on playback when using some intensive FX applied (Neat Video, motion title graphics, etc), but this release is really a breath of fresh air and has me excited about editing again. I was really dreading rebuilding the projects I had done in Vegas over to Premiere Pro CS6 - which I believe I may finally be able to retire.

My deepest gratitude and thanks to all the programmers who worked on this update!

Seems very similar to what I am experiencing. I suspect hardware incompatibilities to be honest.

Installed the update, rerendered some stuff I was not happy with, there is an improvement although, I still get the random flashes. Is multi-camera using NewBlue Chroma screen so, to be fair heavy on any machine.

I like where you guys are taking the product, I have not lost faith but, it is all a little frustrating at the moment.

I also got some severe glitching here (GTX 1060) - both when previewing and also when rendering - but was able to make it disappear totally by setting "GPU acceleration of video processing" to Off.

Having an i7 8700K processor previewing and rendering seem to run more or less just as fast after this. Only bad thing was the hour wasted for checking what plugin or other setting might make the glitching before I found the usual culprit - the GPU acceleration. Looking back this "feature" actually has cost innumerable hours since the beginning where i.e. some FX'es gave different results depending on GPU accell. or not.

My preview is mostly okay but rendering is not useable. For me it hangs with Intel QSV, so my only option is GPU off. That does work perfectly. A semi-complex 5 minute video renders in 7 min. with my 1050 enabled, but 21 with the CPU only (Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz), so for me there is a big penalty on longer projects.

Same with my Radeon R380 card. Renders have periodic random horizontal lines. Think lack of acceleration is frustrating on a short video? Try a three hour multi camera concert video. I upgraded to 15 largely for the promised speed increase. I feel this should be fixed on this version before a new one is released.

People with errors here, please do file support tickets with Magix. I'm not sure they are aware of the extent of problems with acceleration.

I'm using Coffee Lake CPU and since I disabled iGPU in Bios most of my problems disappeared. Running everything of the 1060/6...just sayin', give it a try!

[I believe VP has some memory access / sharing issues between CPU&GPU and since there's old OpenCL code used this might crash with more modern Windows features etc..until this gets fixed, simple is safe]

Well crap. I had originally attributed these random white line dropouts to using GPU rendering. I have now managed to duplicate this problem even with Sony MXF, which I use quite a lot as an intermediate. This is completely new (for me) to 361. A sample clip is attached. Yes, I have reported it to Magix, but would love to know if anyone has a suggestion or has experienced this.

@JoeAustin

What are we looking for in your sample video? I don't see "white line dropouts", but I do see severe panning judder.

@Kinvermark Not just me then?

@Grazie  not just you. i can´t see the white dropouts either.

@JoeAustin Perhaps its a driver issue, or a codec issue. Try playing in on VLC to discard a faulty codec installation.

When I watch the video here, I don't see them. When I play the file, they occur the same every time at about 5 to 6 seconds. Maybe video scaling is hiding them? Did either of you download the file? Or did you play it online?

@JoeAustin i've downloaded it and it plays fine, can you share the original rendered file? I mean through mega, zippy share or any other.

I've managed to capture a frame that shows it well. Right over the word "The"

@JoeAustin i've downloaded it and it plays fine, can you share the original rendered file? I mean through mega, zippy share or any other.

That'll be a challenge. It's a 90GB MXF file.

Good suggestion. In VLC, you can't see the effect. Thought it might be deinterlacing, but turned that off. In both WMP and Potplayer, it's evident and repeatable.

@JoeAustin i can not find those glitches . Here are the result of my test, i've located the exact same frame that you uploaded but the glitches are not there. So it should be something wrong with your computer's videocard, Driver, Codec or Media Player.

VLC use its own internal codec, any other player use the codecs installed on the system. So it's very likely to be a codec related issue.

It would certainly appear to be the case. It's odd that it's repeatable. I've never encountered this until recently. Thank you for taking a look.

ZigoH was on the right track. It's a problem with the Radeon card, or driver. I confirmed this by connecting a display to the motherboard video port. Sure enough, no dropout. Have the latest drivers for the R9 380, so maybe I'll try removing and reinstalling them. Hopefully it's not a hardware problem.

Hi OldSmoke, I sent you a PM. Will you check, please?😰
