video problems using H264 profiles

[Kristop]

Hello,
I've captured a video stream through a capture board, using Yuv coding, in HD 1080p 60Hz, with vlc 2.2.4.
Using the H264/X264 codec (in a mp4 video), I tried different profiles :
- with the "high" profile, the videos can be read by all the video software (AVS, Movie Studio), but I need a better quality
- with the "high422" profile, only vlc can read the video.

When I analyze the video format (using format reader sw), it gives the following characteristics :
- high profile: 1920x1080x12, Baseline@L4.2, ref frames: 1 image, no CABAC, isom (mp41/avc1) codec, 21,5 Mb/s, YUV 4:2:0, 8 bits
- high422 profile: 1920x1080x16, High 4:2:2@L4.2, ref frames: 4 frame2, no CABAC, isom (mp41/avc1) codec, 20.1 Mbps, YUV 4:2:2, 8 bits (the fact that is says no CABAC is strange, I am pretty sure it was on in the vlc parameters).

Does anybody have a cue of what the problem could be ?
