17: hardware acceleration

"Magix has relied more on the Windows 10 GPU "HDR" display mode, which is inferior"

There's nothing inferior about taking that route. Windows HDR is the exact same quality as HDR through any hardware output card.

"Magix! Vegas 17 in its current state cannot be used for any serious work at all."

I just used 17 to complete a 2.5 hour long 4 camera 4k project for a high paying client, and it sailed through it far smoother than Vegas 16 ever would have (or any previous version for that matter, not a single crash that wasn't caused by a third party plugin), rendered it faster, it was colored far better, and the client loved the results... so I'd beg to differ.

@fr0sty, my Friend - the funny part is that the only projects I actually sold to people on BDs and DVDs) have also been multi-camera, classical music performances of some world-class musicians I edited, graded and authored using Vegas Pro software :) In Resolve I only did some features and shorts I did in most part for free (but then, video/film shooting and editing is just my serious hobby, or second profession)..

So when I'm saying now that - if I were to continue such M-C projects in "out-of-the-window" look (meaning UHD resolution and 50 fps) - unfortunately, I couldn't do it in Vegas Pro in its current state. Of course, I could use proxies etc. - but what's the point if Resolve cuts through like it was butter? Unfortunately, multi-camera editing is still much better in Vegas - and that's why I'm disappointed when every new release still has playback acceleration problems. And I don't need to explain to you how important the absolutely smooth playback is when you must keep all 6-10 in perfect A/V sync...

Also, you wrote: "There's nothing inferior about taking that route. Windows HDR is the exact same quality as HDR through any hardware output card."

Oh yes, there is - GPU's colors are Windows - dependent and as such, they may only happen to be accurate, while dedicated I/O device like one of those from BMD are OS-agnostic, colorwise. Lots of discussions on this very topic on the BMD's Resolve user forum...

If you know how to set up your GPU in windows, and don't make any changes to the color settings, I don't see that being an issue. If you've got info that contradicts that, I'd be happy to read up on it.

Yes, there is lots of discussion on the Resolve forum, but the most compelling arguments are for frosty's position. I have a BM decklink card, but I cannot see any difference between its output and that of Vegas through Windows GPU. (I think older Mac's are more problematic in this way due to some weird gamma settings.)

Um, regarding outputs, with Vegas, is 10 bit output possible at all without using a "pro" type graphics, be it AMD or NVIDIA? Can't imagine 8 bit HDR looking good for that matter.

Totally independent from your graphic device 10 bit output is possible for X-AVC, several flavors of AVI, HDCAM SR, images sequences (up to 16 bit and even float point). Not sure about ProRes in VP17.

My point was that two GPUs in a system are not used really by Vegas. What is a difference to Resolve.

Hopefully the work will improve the playback by AVC-I too (what, by the way, is an acquisition format used by the FS7 for example).

Magix Intermediate now supports 10 bit as well.

However, this question seems to be referencing 10 bit preview, in which case, yes, Vegas is the only NLE I know of that supports 10 bit HDR previews out of any HDMI 2.0 HDR capable GPU, not just the pro models. You must make sure windows is in HDR/deep color mode on that monitor.

if I could suggest anything at the moment would be adding ability of I/O devices like Decklink to send the HDR10 trigger to the UHD TV whenever the project is set to HDR10 in its properties; I guess Magix has relied more on the Windows 10 GPU "HDR" display mode, which is inferior - plus, when using a proper I/O card, there is currently no way to tell the HDR-capable TV to switch into its HDR10 mode (not speaking about HLG as my Samsung doesn't support it, anyway).

That is not to 100% correct. I use the Decklink 4K Extreme 12G too. I have combined that with a Sumo - that can be switched both to PQ and HLG manually. And if you would use a Sony HDR-TV - well most Sonys can be set to HDR manually too.

Thank you, fr0sty!

Yes, that's what I had in mind.

I can report that using VP17 with nVidia 1060 GPU has made a massive difference in timeline playback speed for me, using XAVCS 4K on a 1080 8-bit timeline, GPU decode enabled [check if your default IO is Intel] , Intel iGPU disabled, dynamic RAM disabled, latest nVidia Creator drivers. I drive 2 monitors of this, 4K main/edit and FHD external preview.

my current Win10/64 system (latest drivers, water cooled) :

Intel Coffee Lake i5 Hexacore (unlocked, but not overclocked) 4.0 GHz on Z370 chipset board,

16GB (2x8GB Corsair Dual Channel DDR4-2133) XMP-3000 RAM,

Intel 600series 512GB M.2 SSD system drive running Win10/64 home automatic driver updates,

4TB 7200RPM NAS HGST data drive,

Intel HD630 iGPU - currently disabled in Bios,

nVidia GTX1060 6GB, always on latest [creator] drivers. nVidia HW acceleration enabled.

main screen 4K/50p 1ms scaled @175%, second screen 1920x1080/50p 1ms.

Will this get added to Vegas Movie Studio? The software is unusable without AMD GPU acceleration.

@Dinu-Madau please repost your question in your own thread on the relevant Vegas Movie Studio forum. Thank you.
