x264 with 2-pass and auto bitrate

Post by isoloist » Sun Mar 22, 2015 1:33 am

I am using Mediacoder x64 version 0.8.33.5685 and trying to convert a blu-ray m2ts file to a H264 format file. Property of m2ts:
Format : AVC
Format/Info : Advanced Video Codec
Format profile : High@L4.1
Duration : 2h 7mn
Bit rate mode : Constant
Bit rate : 34.5 Mbps
Width : 1 920 pixels
Height : 1 080 pixels
Display aspect ratio : 16:9
Frame rate : 23.976 fps
Bit depth : 8 bits
Stream size : 30.7 GiB (90%)

I want to convert it to a H264 High10 5.1 format file with 2-pass, bitrate ratio for auto bitrate, and all others keep the same, but I found when I was using bitrate ratio higher than 60% for this file, mediacoder will pop error 14. I tried lower ratio for this file and 100% ratio for other files from same blu-ray disc and all works. So I am wondering is there a limit on bitrate or something like that causing the error?

Thanks

I believe High10 profile with 5.1 level has a limit of 720,000Kbps (or 720Mbps) for the bitrate so you're not hitting a limit. Maybe try different settings such as setting the bitrate yourself?
In theory, theory and practice are the same. In practice, they are not.
