Hello Magix, long time no see :),
I have to say, this is the first time for a long time I need to express how great improvements you actually did. VEGAS 17 is far better in performance. I can easily edit & finish 4K projects with much ease. I see timeline performance improvements. No major lags between cuts even for H264 files. I cannot be happier about this outcome more.
Except one thing. Which never changed since I uploaded my video dated more than 1 year ago in VEGAS 16 here:
In this specific video, you can see in the end absolutely random crash (freeze of the program), which is now more than doubled in VEGAS 17. So on one hand, VEGAS 17 have great performance, but I need to restart it like 90 times during any project I edit. This behaviour can be replicated on every machine we have in our studio. Even on Trial version of VEGAS 17. AMD systems, Intel systems - always the same thing. It doesn't matter which Windows 10 version we are using. We tried that a lot. Newest drivers, newers codecs, or fresh install, older, newer. It is always the same. It keeps crashing. Not just us, but many users - as I said. Even on Trial and fresh installed PC.
- You start edit video.
- Cut it for like example 3 minutes.
- Then in one out of 20-ish playback preview ... you hit spacebar for playback and you get stuck your image on some frame.
- You will see that preview window is freezed (you see dots loading probably next frame - which will never happen) -> (....)
- During that time, you can actually save your project. You hear audio. And preview on timeline is still going without any video preview.
- Once you will try to stop playback preview - and these dots are still frozen - you get Crash.
We called it in the team "MERCIFUL CRASH", since when you work around that, you can actually learn to hit CTRL+S and then smashing X or Kill software from Task manager and load-up your project to continue work. Problem is, when you need do that every few minutes.
Once again: I strongly believe, this has to be unmanaged exception. It's dated since VEGAS 15, VEGAS 16 intensify that behaviour with "MERCIFUL CRASH" (you can save project before crash!), a then in VEGAS 17 is this behavior upped to the max. I keep telling myself, that at least we have smooth playback now. That's only thing keeping me sane on this... :)
For sake of the argument, I will update here my specification:
Windows 10.0.18362
Intel Core i9-9900K, 3,6GHz
32 GB DDR4 RAM
RTX 2080 Ti Founders Edition
2TB NVMe + 1 TB NVMe storage
NVIDIA Driver: Studio Driver, 431.86
So, that should be covered... or.. we can even add this AMD build we did for VEGAS to tryout performance:
Windows 10.0.18362
AMD Ryzen 5 3600
32 GB DDR4 RAM
AMD Radeon Nitro RX 5700 XT 8 GB
1 TB NVMe + 2 TB HDD 7200rpm
With newest catalyst drivers.
Same result with random freezing and crashing.
Lastly, but not last, here is the MediaInfo for one of the videos which happen to crash the preview. But it's more like it crashes randomly, it's not only H264. But since I am editing most of the H264 videos, that's keeping to crash most of the time.

Let me know, if I can help more with debugging.
But I think I pointed out satisfying information for smashing this bug out of the VEGAS once and for all.
Thank you!
