Slow render or GPU not accelerated? - Vegas 15 PRO

SGvagon wrote on 11/13/2020, 4:47 AM

Hello,

I have Vegas PRO 15 and try render my movie. But, if I put videos from my phone or 720p MP4 files to Vegas, editing is very laggy and render takes years to complete ( 100% CPU and 5-10% of GPU usage ) . I think, that this problem is somewhere in Vegas.

My PC spec is:
Intel Core i5 6500
Nvidia GTX970 4GB
16 GB RAM
250GB SSD WD Blue + 1TB Seagate Barracuda 7200
Windows 7 PRO x64bit

Videos from Z3 Compact is in 1080p 60 FPS, here is MediaInfo

It must be problem in these files or GPU acceleration. On AVC render it shows No GPU available .

Is this problem solvable? Thank you in advance.

The most likely reason is that the video has a Variable Frame Rate (VFR). VFR is not a favourite of Vegas Pro. There is a long history of this on the forum - perhaps do a forum search re variable frame rate.

The most offered resolution is to transcode the video to Constant Frame Rate. Many ways of doing this are offered in previous posts.

SGvagon wrote on 11/13/2020, 5:35 AM

I see, that maybe is an issue. And what is the quicker solution to fix that? Or is it normal, that CPU is on 100% while rendering these VFR files?

Dexcon wrote on 11/13/2020, 5:52 AM

It's probably more than 'maybe'.

Or is it normal, that CPU is on 100% while rendering these VFR files?

Vegas Pro uses CPU much more than GPU for rendering other than HEVC and one other, though others on the forum will be in a much better position to comment on this issue.

@SGvagon
Which build of VPro 15 do you use, the latest and best is 416
If you don't see a GPU in the program I think you have to update your Nvidia drivers to the latest available, that is the 457.30 WHQL of 2020.11.9
To overcom the variable framerate of the FHD file(s?) you have to convert them to constant Bitrate in a conversion program as the free Handbrake you find here https://handbrake.fr/

SGvagon wrote on 11/13/2020, 6:07 AM

@j-v I am using this latest build 416.
I see GPU in Vegas option, but for example in AVC render if I click on Check GPU, it says that I haven't got any GPU

And I have actually 457.09 Nvidia driver. So I try update it on the actual 457.30 if this helps.

I render now 3 minute video almost 30 minutes to MAGIX AVC/AAC MP4 - Internet HD 1080p 59.94 fps (NVIDIA NVENC) 😐 .

j-v wrote on 11/13/2020, 6:14 AM

Sony AVC is already a very old codec used in many Vegas programs before 15.
What you now are doing by using the Magix AVC is the best option for you at this time.
For faster rendering with CPU and GPU you need other and better hardware as CPU and Nvidia GPU's and the latest Vegas Pro 18

Very likely because GPU is simply not available for that render option. If it were available, it would provide a field option. It shouldn't be taken as there is no GPU on your computer, its just that its not available for that render option. Please remember that Sony render options pre-date GPU accessibility in Vegas Pro AFAIK.

SGvagon wrote on 11/13/2020, 11:18 AM

And what about this software https://www.voukoder.org/ ? What I see, its little bit harder to set it up, but redner should be two-three times faster.

j-v wrote on 11/13/2020, 11:26 AM

Try it, nothing wrong with in VPro 18 and works well

lenard wrote on 11/13/2020, 5:37 PM

Do you have intel quick sync decoding turned on?

That will make things go faster, I think there's also Nvenc hardware encoding in v15 if you did want to GPU encode

SGvagon wrote on 11/14/2020, 2:32 PM

@lenard I have there only Intel HEVC, and it slow too on this various framerate.

I found quick solution with FFMPEG script, which encode these files to constant bitrate.

ffmpeg -hwaccel cuvid -c:v h264_cuvid -i input.mp4 -c:a copy -c:v h264_nvenc -r 59.94 output.mp4

Vegas then rendering much faster.

lenard wrote on 11/14/2020, 5:51 PM

with vp15, the only hardware decoder is using intel quicksync, and with your generation of CPU I believe you must have your motherboard video port (as opposed to Nvidia video card) connected to a monitor or a dummy monitor plug for it work. That will reduce load on your cpu too

Musicvid wrote on 11/14/2020, 6:25 PM

Your need to correct the Variable Frame Rate for Vegas 15 comes first. It is not trivial.

Recode to Constant Frame Rate, Same as Source, in Handbrake.

Drop back in, and we'll take it from there. The rest of the speculation offered about GPU is ridiculous until you have corrected that single, overriding issue.

@SGvagon Nice. Filing that one away... probably as optimal a fix as there is.

Would anyone know how to increase the quality of this setting?

I tried it on aa 4k 75mbit/s AVC, the encode is 3.5mbit/s and looks like the pixilated mess you would expect. I have not had good luck at all with NVENC and VegasPro18. It doesn't matter if output is from OBS or Handbrake, or media info says CBR or VFR, so this interests me, but I don't know command line

@lenard “Would anyone know how to increase the quality of this setting?”

The link in my profile to VFR2CFR zip allows quality increase/decrease. You can also add into your syntax -cq n where n default is I think 23, lower numbers are higher quality, 18 say, will normally give a much bigger file than original, but high quality.

This is what I use in VFR2CFR...

ffmpeg %_DFPDISPLAY% -y -i "%~1" -pix_fmt yuv420p -c:v h264_nvenc -rc:v vbr_hq -b:v 100M -g %_GOPLENGTH% -cq %_CQ% -bf:v %_BFRAMES% -r %_FPS% %_AUDIO% "%~n1"-[CFR].mp4

Obviously these are just my own named variables below, but you get the idea ...

%_DFPDISPLAY% %_GOPLENGTH% %_CQ% %_BFRAMES% %_FPS% %_AUDIO%

JN- wrote on 11/15/2020, 7:29 PM

@lenard I've added in the batch file I originally used 03 ... .bat, you can use that also, just make the necessary changes if any are required. The REM comments at the start of the file explain what to change.

I found that using -CQ gave slightly better quality than -QP. So the syntax you use is faster than what I use.

When using -CQ, it's important to use -b:v 100M also, for my syntax.

Howard-Vigorita wrote on 11/15/2020, 10:27 PM

@lenard The ffmpeg h264_nvenc encoder presets for quality are:

  -preset            <int>        E..V...... Set the encoding preset (from 0 to 18) (default p4)
     default         0            E..V......
     slow            1            E..V...... hq 2 passes
     medium          2            E..V...... hq 1 pass
     fast            3            E..V...... hp 1 pass
     hp              4            E..V......
     hq              5            E..V......
     bd              6            E..V......
     ll              7            E..V...... low latency
     llhq            8            E..V...... low latency hq
     llhp            9            E..V...... low latency hp
     lossless        10           E..V......
     losslesshp      11           E..V......
     p1              12           E..V...... fastest (lowest quality)
     p2              13           E..V...... faster (lower quality)
     p3              14           E..V...... fast (low quality)
     p4              15           E..V...... medium (default)
     p5              16           E..V...... slow (good quality)
     p6              17           E..V...... slower (better quality)
     p7              18           E..V...... slowest (best quality)

You can list all the options with this command:

ffmpeg -h encoder=h264_nvenc

I made some small changes to VFR2CFR.

I would never use 264 HW encoder for intermediate.

SGvagon wrote on 11/20/2020, 8:38 PM

Ok I have good news guys. This slow render doing default Project properties, where was Field order on Upper field first. So I set it up on None (progressive scan) , and now I can render original files with variable framerates much quicker than before (from hours it almost realtime now) .

So I shouldn't use FFMPEG before editing and rendering in Vegas. I can use raw files from my phone now. It is strange, but it works guys, only Field order did this slowness render and edit.
