Multiple Rendering Issues Using H.264 in 64-bit Sony Vegas Pro 12.0
on Jul 17, 2015 at 4:56:47 pm

Hello, and first of all, thank you for reading.

I recently installed the 64-bit H.264 codec via SourceForge in efforts to improve my YouTube upload quality. After some basic tinkering with the settings and my first try at a render, I was unsatisfied with the results. The quality wasn't noticeably better than my previous render settings (though the size did seem smaller) and one of my Video Event FX was completely missing. These were the render settings used initially.

I then decided to crank up the quality settings under the codec configuration menu and try again, but alas, I was met with a terrible error.

These were the tweaked configuration settings.

I've spent hours shuffling through Google and doing my own troubleshooting to try and find the cause, but to no avail. No one setting seems to cause the error and nothing I could find on Google was even remotely related.

My second problem came to me through the troubleshooting process, when I noticed that the aforementioned disappearing Video Event FX are also missing with the regular render settings that I've used for months. Further investigation lead me to find out that the FX also disappears simply when changing the preview quality to anything higher than "Preview" even when moving frame by frame. This is the desired effect (created using Glint).

And the apparent result (keep in mind that the bit of glint seen below is a part of the image itself and not a result of some butchered effect).

This has been eating at me for going on day 2 now. Any and all help is greatly appreciated.

My suspicion is that you have overwritten one or more Vegas codecs by installing one or more from "SourceForge". You could try uninstalling Vegas, and reinstalling it again. If that doesn't help, you may need a more complete uninstall of Vegas followed by a reinstall. That subject has been covered a few times recently, so I would search for those posts to learn how to do a thorough uninstall.

I've only installed 1 thing from SourceForge and it was the codec, I will give reinstalling the codec a try.

Your bitrate in the screenshot is 50Mbps. That is a truly massive bitrate for HD with the AVC codec and you are not going to see a difference between any AVC encoders at such high bitrates. At such high bitrates you are not going to see differences between Medium and Veryslow encodes in x264. That bitrate is over twice the average bitrate of HQ Blu-rays and 5X of Youtube.

Second what is the High10 profile you chose in your failed encode try. That is probably the source of your failed encode. Video for Windows (AVI) can only ever be 8-bit. Also your sources are probably only 8-bit.

The Medium/Veryslow point is a good one, I will adjust that setting. However the 50Mbps bitrate is the conclusion I came to with the references below. Either way, I tried turning this down to as low as 1,000 and the error still occurs.

https://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels

The second link is also where I come to the conclusion for the High 10 profile, and this setting does not alone cause the error, nor did any other lone or couple of settings that I tried. I have to basically put everything back to the settings used for the first render for it to work.

Funny... that reference is telling you to use an MP4 container yet you insist on using an AVI container. This is part of your problem. H.264 has no business being in a AVI container in 2015. We did this 10 years ago when there wasn't a proper MP4 container to use. You should use the MainConcept AVC or Sony AVC encoder that's already in Vegas Pro.

Looking at your Youtube link, there is absolutely nothing about 50Mbps bitrate. For 1080 high frame rate it suggests approximately 12Mbps.

This Youtube encode pages says nothing about High10 profile. I am not sure what on your second link could make you think High10 is what is required given the Youtube encode recommendations. Just leave the Level setting at Auto.

Looking at your two x264 setting screen shots the main differences are the High10 profile and them colorspace option is different from the encode that worked.
