I started testing this version today. I still have 29 days left to reach a sensible conclusion.

So far I'm liking the new features. They are doing what they were designed to do.

Just Vegas SlowMotion that is generating some weird artifacts, a sort of preview glitch and Vegas Screen Capture that doesn't work here.

But it is still early to reach a conclusion. I will do more tests.

Screen cap works fine for me, but yes, the optical flow slomo can produce glitchy results sometimes, and needs to be refined.

Same here with Screen Capture, only get a blank window

Optical flow seems to do a good job of water and boats, surfers, etc. Looks like Twixtor to me.

This is what I get with screen capture. Can someone post a video of what is happening when it fails?

Did a quick test with my old stabilizer (Mercalli 4.0), slow-motion software (ReSPeeder 1.0), and my screen capture software (Movavi), and they all work very well. I was able to get vegas stabilization FX to work but it is nowhere as good as Mercalli. Can anyone verify if the Vegas versions are or aren't delivering good results versus these other stand-alone programs?

Other than the occasional glitching, I'm getting results from the optical flow slomo that are on par if not better than what is offered with Premiere/After Effects. I was able to slow down 24p footage to 3fps, then scale that back up to 24p using optical flow, which should look like a horrible mess, but, aside from a little warping around the edges of objects, it worked very well. Dark footage doesn't track as well, though, and I've seen artifacts pop up in complex scenes.

Also was trying to install the Steinberg Spectral Layers 6 audio program but I own Cubase 8 Elements and of course, Steinberg's licensing mechanism went nuts on me when it found other Steinberg programs and wouldn't load. I don't want to spend several days sorting it out only to find it's kinda not worth it. I currently use Sonar/Cakewalk as my DAW and have Izotope RX 7 for fixing audio things as well as hundreds of audio plugs from Waves, Universal Audio, Fabfilter, even more Izotope, etc. Does the Steinberg program offer anything new to someone like me with my overkill(?) on audio plugs other than it looks like it may work a little better within Vegas?

Something still missing in the Vegas Pro stabilizer is a CMOS correction. If your source video is based on a CMOS recording I would strongly recommend to use a CMOS correction before using the Vegas Pro stabilizer.
For my own footage I always apply the ProDAD CMOS Fixr before the Vegas Pro stabi (made an FX chain with both) and my results are on par with Mercalli. So I could drop Mercalli now but I'm forced to use a CMOS correction before.

To the screen capture tool:

Same things we mentioned for Movie Studio now applies to Vegas Pro 17.

On my laptop that screencapture tool works (start) different in VMS 16 and VPro 17.
In VPro I get only a black screen and I found that trough rightclick on the taskbar pic you have to choose the capture ( or other) function. Look

Interesting finding. To be sure: You right-clicked the black recktangle or an icon in the taskbar?

I have to rightclick this icon on the taskbar

I found another thing.

I s it as designed that this screencapture tool after the first start can be used as a stand-alone.
When you pin that screen once to the taskbar it can be used as a stand-alone in Windows without VP17.
Look

Nice one.

I tried the new slow motion. I initially used a 10s clip of UHD 25fps. Its a right to left pan, just rubbish shot. I set it to .25. I saved rendered all to FHD then observed results.

It was lovely, really, very nice. Then I noticed two different issues. There are really peculiar artefacts on the left and right side of the screen, maybe 5-10% in, you couldn’t really use it, pity. The second issue was the tip of a domed building was wobbling like mad, I actually had noticed this first.

So I selected a FHD version of the same clip, but the results were the same. Then I tried cropping in, just to see if it would eliminate the peculiar side frame issues. This really messed everything up, the 5-10% became much bigger, everything really much worse.

This needs a bit more work. Pity because before I noticed the problems it looked really really nice.

I expect that a pan is going to show these issues more clearly, it’s possible that other types of shot may not suffer in this way, or as much.

What you observed may be one of the core properties of optical flow processing which not only affects Vegas Pro. Optical flow is not the best solution for any kind of source footage. The more clearly structured fore- and background are, the more optical flow technology fails.

Fair enough @Marco. If those artefacts can be dealt with, it has a bright future, at the moment, under the conditions I tested, not so much.

While I have your attention, hopefully, can you point me to where the new lossless Intermediate render file type is located, I have searched for it, cannot find, thanks.

Is the Screen Capture tool based on (open source) OBS Studio?

@Former user
Sorry, I don't know. My system is Intel based so I have no access to NVIDIA based features (which these lossless (not uncompressed) intermediates seem to be). It may be visually, not mathematically lossless, but I don't know.
