SONY VEGAS 12 Mainconcept rendering problem.

[Colin Morris]

Hi Graham,
Exact….well you would have to dig down into the system info and what other software plug-ins are running.
John did say to have up to date drivers and see what others are running successfully.
Here is where I first participated in the discussion:

Well Sony seem to be recomending the Geforce 570GTX on their website which is a gaming card.. also I’m having to render the video file and audio files individually…was thinking about resorting back to Premiere..sony need to address these issues…also there is a issue with mainconcept codec.. when rendering MP3’s the sound come out as if its stuttering.

I too have found to my surprise that the MainConcept MP4 encoder is broken in this release. Yes I use a Quadro graphics card. Yes I have turned off GPU acceleration in the options and the render options.

I am encoding videos for iphone/ipod as part of my wedding video package and have my presets which work well in these devices.

I noticed when I upgraded from SVP 11 to 12, with the exact same presets, that the videos now have severe pixelation artifacts, especially with images which have movement and small objects. These were certainly not there in the previous release.

I run a commercial business and this has made this encoder for this release unusable. I have had to revert to using the Sony encoder to get output which is slightly lower quality by does not have these artifacts. For reference, I encode in 25 fps, but found that it doesn’t matter as setting to 29.9 fps makes no difference.

I have also checked the video output produced by the MainConcept encoder and it appears that some of the settings you set in the configuration for the encoder are ignored (for example the “reference frames”)

My advice, is stay clear of this encoder until its fixed.

I have lost a lot of time with this main concept problem….have switched to the Sony avc codec.
Turning off the gpu does not help, and forget 2 pass renders…it just won’t happen.
Vegas 11 works fine, but I have a month of work in 12 and can’t go back now.
I have also the latest drivers and updates which doesn’t help main concept or the always crashing new blue titler.
I have sent in at least 20 crash reports to Sony in the last 2 weeks. My client sure wonders why i still edit on Sony Vegas…..sometimes I wonder why myself.

If you are really really stuck, and you know you can render from VP11, what I do is render to a Lossless Format, Lagarith, import THAT file into – here that would be VP11 – and render out to the MC.

Lagarith is a free CODEC and is blisteringly fast:- https://lags.leetcode.net/codec.html

I have an update that may of interest, if people are still reviewing this thread looking for solutions.

This issue with the artifacts in the Mainconcept renderer seems to been addressed with a bug fix release build 563.

I didn’t see reference to this issue in the release notes for that release, so we are obviously getting “quiet” fixes for things that are broken, so it is still worth sending in problem reports, even if it appears that they are ignored.
