Vegas pro 15 LUT Filter Very Slow

I've been using sony vegas since version 11, it's simple, very fast for cutting, but, outdated.

I considered switching to Adobe Premiere this year but got cought up in work and continued with vegas 13.

Vegas 15 keeps the usual bugs i know from 13, vegas freezes sometime when i paste a track compressor onto another clip, the famous Defocus plugin crash on AMD graphics cards and so on.

One new thing that caught my attention was the LUT Filter, but, it's not GPU accelerated, at least on a rx480, all CPU and no GPU, it's very slow even on FullHD footage, 4k is out of the question.

The user base of Vegas users is big, we are gonna transition to Adobe at some point, we have no choice, with all the cameras now shooting c-log,slog,v-log.. you need a Lumetri like panel for color grading and properly GPU accelerated.

Especially for log files and the later HDR editing, LUTs will be of limited value anyway. What we will Need is a complete Color Management System, and such a System has been implemented in Vegas Pro 15 based on ACES 1.03.

With ACES 1.03 you will be able to grade log to both rec709 but also to rec2020 what we will Need for HDR. Vegas is well prepared for HDR at the Moment, we miss a waveform Monitor where we can Switch the y-scale to nits, maybe a rework of the Color correction filters (if at all). And we have the H.265 Encoder with 10bit 420 as defined for HDR, and will Need metadate in Addition mainly.

An important Point is to improve the preview capabilities, since this ACES mode works in 32bit Floating Point only, what requires a powerfull machine.

I doubt the masses of wedding videographers and youtubers care much about HDR.

I tried what you suggested and you can't edit like this, right now 32 floating point it's slow, in davinci works perfectly.

Who said something about wedding filmer??

And belief me, I know why I was talking about "powerfull machines". A 8 core PC is the minimum, the footage should be 10bit UHD but not 8bit. But the performance of Vegas must be improved, otherwise it will be hard to run such an ACES 1 workflow.

It would be unfortunate if Vegas went in that direction- who has 8 core machines and only uses 10 bit UHD footage? I'd just switch to Resolve if I were such a user. Vegas already has a narrow user-base.

I would like to see a rework of color management and correction with a proper preview window and simplified correction controls that work with LOG and regular footage. I really need it to have better real-time playback.
For ACES, who makes the IDTs and how can we get a better set of them in Vegas? This approach only seems to work with a select set of cameras that have been defined. I like it a lot in theory.

I have here my 10bit HDR footage, slog from my FS7. And also a 8 core machine. And beside Vegas also Edius Workgroup and also Resolve Studio. ;)

And the color management based on ACES 1 is also what you find in Resolve 14 today. That is state of the art.

The preview capabilities must be improved, very true. But that is well-known.
