After uploading video to YouTube it complains there may be A/V Synch issues. The YouTube help pages seemed to verify I had the render settings set correctly. Here they are:
Sony AVC .mp4
Audio: 128 Kbps, 48,000 Hz, 32 Bit, Sterio, AAC
Video: 29.970 fps, 1440x1080 Progressive, YUV, 12 Mbps
There is one setting that you listed that I would never use for YT.
1080p Video Size for YouTube should be 1920x1080 with a Pixel Aspect Ratio of 1.0 Square, not 1440x1080.
This might be what is confusing YouTube.
Are you starting off with the actual Internet Temlpate in Sony AVC/MVC = Internet 1920x1080-30p.
Also, I would increase the bit rate of your Audio to 192kbps or higher.
This is the template I use, and I have never has sync problems of YT.
