Slow Render Times using MainConcept AVC/AAC

Roxas1359 wrote on 5/17/2017, 11:17 AM

So I just recently upgraded to MAGIX Movie Studio Platinum 14 after using Sony Movie Studio Platinum 12 for many years and I seem to be having problems with rendering 720p videos. When using MainConcept AVC/AAC the render times take close to 4 or 5 times longer than they used to. It's worse when it's a video being rendered in 59.994 frames per second with it taking anywhere between two to three times longer than what it used to. My PC specs are an Intel i7-4790K, a Nvidia GTX 1060 6GB SC for GPU, and 16 GB of GDDR3 RAM while running Windows 10. My render settings are listed in the picture below. I do have the project settings to render only to Good (Full) as well. These render settings are the same for when I render 60 FPS videos only the frame rate is set to Double NTSC. Any suggestions? I'm too used to having fast render times and having it take 1 to 2 hours for a 27 minute 29.997 fps video is something I'm not keen on getting used to.

These are no projectsettings, this is a preview setting. Have nothing to do with rendering.

What are your projectsettings? (Menu Project/ Properties)

You mean the Project Properties? Here they are:

Thank you.
I cannot find there something that causes slow renders.
How does the Sony AVC render your files.
For myself I use that codec, renders a little faster with also good quality.

It rendered faster than the MainConcept one, but I've not tested rendering a 60 FPS video with it yet. Took about 30 minutes for a 28 minute video at 30 FPS though so it's much faster than it. I just find it weird that MainConcept is so slow for me now though.

Did you try the default Mainconcept AVC template?
Only your bitrate is different and also a bit strange compared to the default.
All default templates have a maximum bitrate twice the average bitrate.
In yours they are the same

I haven't tried the default ones yet, so I'll try that and see if that yields long render times as well. If worst comes to worst then I'll just render using Sony AVC instead.

Please note that GeForce 337.88 or Quadro/Tesla 341.05 (an R340 driver) or older is required for GPU-acceleration. These drivers can be found at: http://www.nvidia.com/Download/Find.aspx

@MAGIX_Eric D I've seen this comment more than once on the forum now, and apparently it's also being sent in email support. I'm confused...

  1. Unless I'm missing something, those drivers cannot be found at http://www.nvidia.com/Download/Find.aspx. Offerings there only go back about a year to 368.XX.
  2. The 337.88 driver only supports up to the GeForce 700 series. GeForce 9X0 and 10X0 cards (i.e. Maxwell2 and Pascal) are not listed for that driver.
  3. There are many reports of users successfully using GPU acceleration of video processing with later drivers than the ones you mention. I am wondering if 337.88/341.05 are actually the last drivers that MainConcept AVC CUDA rendering worked on (with an appropriate GTX 400-500 series GPU only). Please clarify.

If you search for ION, Windows 7, you can find the older drivers. But these are dated 2014.

@Nick Hope The drivers referred to in the previous response are the information we provide for GPU accelerated rendering support. While we have communicated with people who have had newer drivers installed and this has worked, we have also seen positive results when rolling back to these driver versions when customers have experienced issues.

Have you tried constant bitrate?

Yes, and the same results still occur. Oddly enough I have noticed something odd though. I often do a bulk recording and then split the different episodes and leave them in one project. I then render only the region encompassing that episode and that used to be fine in Movie Studio Platinum 12. However, in Movie Studio Platinum 14 I've noticed that the time it takes to render triples when I have multiple episodes in one project despite setting the render region to only render one episode. A work around I have to this is deleting the other episodes and leaving only what I want to render on the track. That lowers the time it takes to render back down to a reasonable time. Mind you I'm still using Sony AVC as the MainConcept AVC is still buggy for me.

@MAGIX_Eric D Thanks for the clarification. I think it would be worth you guys using the words "legacy GPU rendering" in this advice, to distinguish from GPU acceleration of video processing, and also mentioning that a GTX 400-500 series card is required.
