[Resolved] How to decrease the render time

4sol-n wrote on 10/17/2020, 3:12 PM

1. My end files are 1-2h long

2. The size of 1h file to be upload to SV is about ~13 GB [ 28k Kbits 1920x1080p 60 fps ]

3. Rendering with Main Concept AVC, values all the same, except resolution, which is needed to be 2560x1440p

4. It takes about 7:30 h to render a 1:40h long file ...... (kill me)

5. My PC Specs:

 

Any tips?

(I can't lower the resolution and the bit rate)

Thank you.

Upgrade the vegas version to the latest VPro 18 of Magix Vegas.

And what next? Main Concept AVC will be rendering faster there or you are talking about other method?

I just read comments about 334 version, it renders twice as long as the previous one.

Not with me , on laptop from signature QSV rendering is fastest , followed by NVENC .
In your case with the Magix AVC codec. Those are a lot newer and better than the old Mainconcept which work only on CPU.

yes and yes

OK, I will brb with the answer after I finish rendering this file and update to magix 18 and will try to render the same file with magix avc

Rule #1: Don't upscale! It does nothing except to make your files bigger and slower to encode. It does not make them "UHD."

Rule #2: When in doubt, refer to rule #1.

As for upscaling and machine encoding, you will never see me go there. It makes no sense, twice.

As for Mainconcept software encoder, Sony AVC is better quality at a given bitrate.

lenard-p wrote on 10/17/2020, 7:09 PM

The game he is playing may be in 1440p, and he wants to preserve the detail. If he is uploading at 1440P to trigger the VP9 codec, which people say give better quality, in my last testing a couple of months ago, it is not necessary for 1080P60 footage, it will get VP9 encoding, 1080P30 however won't

4sol-n wrote on 10/18/2020, 1:35 AM

1440p is for YouTube VP9, for the better quality, I do not want to upscale, but the f YouTube forces me to do that to get the best quality after uploading my video and yes, I'm recording in 1080p.

You can google this issue and see quality comparison 1080p and upscaled 1440p with 0.05 sharpen effect.

It worked and even better than I thought.

Before in v.13 I was using Mainconcept AVC and to render a 1:38m footage it was needed more than 8 hours

Now in v.334, using Magix AVC it needs 4 hours

And if using Magix HEVC only 1:15h! This is ridiculous!

Thank you for the intel. 🙂

@4sol-n

I am well aware of the internet hype surrounding upscaling and VP9; however, I have seen no quantitative tests using SSIM, PSNR, and VMAF to support such claims of alchemy, a pet peeve of mine. Nor am I able to draw such a conclusion based on my experience (signature below). Also, using machine encoders runs exactly counter to your stated goal of maximizing quality, meaning you have completely different criteria than I have chosen to address.

It is time for me to step out of the discussion; you seem to favor speed over quality, I won't be able to address that, but keep testing as you develop a more critical eye and refined techniques. Glad to have been of "some" help. Welcome to the forum, and best of luck!

with that hardware and proper vegas(what i was asking) render time should be max.10min

lenard-p wrote on 10/19/2020, 3:21 AM

It's a 1h38m video, that he's upscaling to 1440p, AND adding sharpening. The sharpening is the important bit. In Resolve the estimate is 2hours, so longer then it takes with Vegas. The reason for this is because Resolve hightly utalises GPU but the GPU this guy and I have uses 80% GPU with without the sharpening, and that would take 38mins, but add sharpening, and the GPU is maxed out and becomes the bottleneck. Yes you could get a better GPU and probably have an encode time not that much longer than 38mins, but not with current GPU.

In this situation with his PC, Vegas actually is faster than Resolve

Actually not only sharpening effect, but with Sony saturation and Sony color correction.

@EricLNZ @dream With even the best hardware available today, there's no way a 2hr video at 1080p 60hz will *ever* render in 10 minutes from VP. That's not a "dream" that's a drug induced "fog" :-)

So dream's 10 minute comment was just that - "a dream".

maybe for you not for me, you need to wake up.

clearly vegas cant do this which is why im talking about vegas for improvements. .

i did 2 hours long video in 10 min at different software.

@dream

It's easy for you to prove, dreamer.
Take a comparable video file upscaling to 1440p, AND adding sharpening, throw your software on the timeline and record the rendering with OBS Studio.

Then we can all see this here - at least I'm very curious.
