Lut filter uses all of VRAM and Ram the memory leak exists since the first build of Vegas Pro 22 i think. There have been reports of other video fx filters with the same problem, i really hope you guys fix the memory leak in this build, third party lut plugins just dont perform the same as Vegas Pros own Lut filter.

@Abubakar Which third party LUT plugin is performing slow?

 

I think he means the native VEGAS LUT filter. I think it's a problem with all plugins, but some of them are affected more or are easier to get problems. I have two GPUs Intel ARC 380 (slot 2) and Nvidia rtx 3090 (slot 1). I have this problem with memory leak while Nvidia is on GPU accelerating and ARC is for hardware decoding.

I can make some tests but for sure this problem is when the display is in Intel ARC. Maybe it's not when display is in Nvidia...

Have interesting thing with HEVC 422 10 bit (horizontal) in vertical project. This is green stripe when changing preview quality.

@Alex-Pitel I tested with the Vegas LUT Filter and didn't experience any memory issues. I'll test again tomorrow though to confirm. My computer is an all AMD computer, see Signature.

Hello, I am surprised really, i don't know but some of us have this problem for a while now, i have 2 computers both Intel see my Signature

Hello Pascal,

By third party plugins i meant OFX plugins for Vegas Pro from other companies, when it comes to playback and render third party OFX plugins don't perform the same as Vegas Pro own Lut Filter Plugin and the lut plugin in color grading panel.

I have 4 OFX lut Plugins for Vegas Pro and using them for years. I tested them for my self to see if the playback is sluggish or not when i apply them, and rendered the same video using different third party OFX plugin that's how i would rank them.

Vegas Pro 22 own Lut Filter Plugin and the lut plugin in color grading panel takes the first place

Magic Bullet Looks, it takes (second place) but it doesn't have 32 bit floating point

3D LUT Creator OFX Plug-In (Third place)

VisionColor LUT Plugin VEGAS (fourth place)

FXHome Ignite Pro 2021 Ignite Lut its the slowest (5th Place)

@Abubakar I am able to replicate the LUT issue with 22.243. With just a 720p project and AVC media with a LUT filter attached to the events and a second on the output Fx I was able to use up all system ram and playback slows to .6fps. I didn't do any editing, just made a few cuts and played it through.

I wasn't able to crash VEGAS though. It gets within 1GB of running out of ram, frees up 1GB or so and keeps playing.

Edit: this is with my RTX4060 mobile laptop with 8GB VRAM and 48GB of system ram (see signature). I can get over 20GB of shared GPU memory in use.

and closed VEGAS:

Hello RogerS, Yes that's the same problem i am having.

Hello Alex, i bought the Intel Arc A380 for decoding aswell. Using the same combo as you are Intel Arc A380 for decoding and Nvidia RTX 3060 on GPU acceleration for video processing. but unfortunately Vegas Pro 21 and 22 doesn't work well if you use this combo and you will run into multiple problems i made a thread about this a few months ago, only the igpu on intel 12,13 &14 gen works good as Hardware Decoder when using it with Nvidia RTX 3060 on GPU acceleration video processing. If you want to use Intel Arc A380 you have to select it as GPU acceleration video processing aswell. But at that point your RTX 3090 is just there as a secondary gpu which ofcourse you dont want. the only down side to using intel igu as Hardware Decoder on Vegas Pro 21 and 22 is that it eats allot of shared memory from your system ram then you have very little ram for the program it self. The new video engine works great but uses allot of Ram form igpu or Vram from dedicated gpu whichever you use as a decoder. That was the first reason i bought the bought the Intel Arc A380 so i would have enough ram and Vram for everything but unfortunately the combo doesn't work.

Another day, another test.

I again tried this using 4K 10bit 422 footage. I applied the LUT Filter on 3 successive clips with total length of a little over 2 minutes and had it repeat playback 5 times. Yes, RAM usage increased from 3.3GB to 7.1GB during playback, along with GPU RAM from 3.1 to 6.1GB. When I stopped playback, after a few moments, system RAM returned back to 3.9GB, a gain of 700MB from the original start of the project before adding the LUT Filters.

I don't see, at least with my computer, the eating up of all the GPU and system RAM that the user is experiencing. I'd have to sit here all day to reach total system RAM and GPU RAM to use up everything.  What LUT is this user using? I am using DJI's LUT for their drones.

I guess the animated text bug has not been fixed?

If it doesn't explicitly say that a bug has been fixed in the release notes, then it has not been fixed. There's a ton of bugs to fix, they can only get to so many at once. This update is specifically meant to address the bugs that it said it fixed. You can still report that "X bug is still here", but just know that unless it was reported as fixed in the changelogs, then it was never intended to be fixed with this particular update. They're working on it as fast as they can with the resources they have. In the mean time, until they can get to all those other bugs, let's help them test the fixes they have in place for this update.

I made a LUT Fx memory leak test project here (video and random LUT included). So far confirmed on 2 NVIDIA systems. Just select the whole timeline and play it on repeat and watch the ram usage and timeline framerate performance.

I made two test videos. I have FOUND an interesting thing. If you close the preview window while playing and then start playing again and open the preview window while playing - LEAKAGE STOPS! You can see it in the SECOND VIDEO!

For this test, I disabled the Intel ARC GPU (I pulled out the power cable from it but didn't pull out the card from the slot) and used only the Nvidia RTX 3090. I have ReBAR and Above 4G settings enabled in the BIOS!

VEGAS Pro 22 BETA Build 243

The new Vegas feature Auto-ducking is broken and unusable when used in a nesting Timeline. It rather boosts the audio than ducks and has a nasty hearable audio glitch (probably where the ramp is).

How to reproduce: first create a parent and nest with some audio tracks in the nest. Observe the master bus volume visually (and hear it as well) on both the parent and nest- sounds and looks OK. Next add the new Vegas audio-ducking in the nested Timeline. Observe (and hear) the master bus volume on the nested Timeline and compare with the parent timeline- now you see and hear a significant boost in the audio on the parent timeline which is NOK.

Audio duck Settings (probably does not matter, but use these to clearly hear the issue):

- Floor reduction -96

- Peak reduction 0%

Found out - REBAR was disabled!!! Bios activating this function, but my processor AMD 3900x doesn't support it!(((

@ALbertoo-gall I think you are trying to show that the render times go up with the LUT filter is added. That's been an issue for a while. Try adding LUTs using the color grading panel instead.

the same result

Vegas 21 is a 2 hour video and it's done in 30 minutes

The color grading panel is faster than the LUT Fx at present and doesn't have the memory leak issue. Of course it will be slower than having no LUT applied.

Sample render test of 35 second long HD media.

Media + LUT Fx: 19.04s
Media + CGP: 15:15s

Test is with my laptop (see my signature.) Rendered with MagixAVC (NVENC) to 1080p.

Hopefully we'll see more performance improvements as the video engine work continues.

Update/response: time with 21.208
Media+LUT Fx: 14s
Media + CGP: 17.5s

Thank you! LUTs using the color grading panel seems working!

@ALbertoo-gall Please add a description of what you are doing and what the issue is when you post a picture. We can't just guess. If you're saying that the LUT Fx is causing VEGAS to run out of memory we discussed and replicated that above.

Seems to have made my old obs hevc recording with 4 stream/layers of audio stable again, it usually crashed once every 15minutes, but now I've been working at least 3 hours without issues. Wonder if one or more files caused the crashes previously that simply isn't happening anymore?
