Bug Report Output video is half green [only with I444 and x264]

So I was trying to get a near lossless recording, so I set Settings>Advanced>Color Format>I444 for better color reproduction. However, with Settings>Recording>Type>Custom Output (FFmpeg) the output file is buggy; half of the video is green.

This bug doesn't happen when using Standard type., or when using the h264 encode instead of x264. I've attached a a screenshot. If for some reason the screenshot doesn't show, you can view it here:

Same here with 0.12.2 in Windows 10. Has anyone come up with a solution? I've tried selecting RGB and recording to UTvideo or huffyuv but the encode will be very choppy, even though it's using less than 10% CPU of a six core haswell desktop CPU recording to a RAID 0 array of two SSDs. I can record using RGB to rawvideo with no issue, but the disk space utilized is nuts.

Here's an interesting one.

If I use I444 and the "standard" encoder, not custom output with ffmpeg, I can record x264, 4:4:4, yuv444p, using I444 with no green.

But with custom output/ffmpeg, I get green.

I would be fine using the standard encoder rather than custom output, however, using the standard encoder, I have no option to not recompress audio - all I can do is AAC.

Is there a way to either fix the green on I444/custom output, or allow us to set wav/uncompressed audio when using the "Standard" encoder?

You could use the lossless recording preset in simple mode. File output will be huge but audio is saved as WAV.

Lossless freezes up immediately, it is broken in I444 and RGB. lossless/utvideo only works at NV12. :( It gives a CPU overloaded error at 7.6% CPU utilization. It works fine in NV12, but is inherently broken at RGB or I444. the " standard" encoder works with RGB or I444, doesn't freeze up ever.. we're so close. :) but no lossless audio outout.

Is there a way in the standard mode to pipe the output to wav? Standard with crf=0 works with I444, but limits you to AAC. I would pay a nice donation for this to be a checkbox!
