MXF wrapper and its NOT the actual video CODEC settings that are causing the trouble. This tells me that Vegas' trouble with XAVC-L (H.264 long GOP, UHD 100Mbp/s) comes entirely from a problem with the.

It's the same exact video stream just moved into a different file format. The result? XAVC-L video plays back very smooth in Vegas with no trouble at all in an MPEG TS file. (transport stream) Mind you.this is NOT a re-compress, it's simply taking that exact video out and re-packing it into a new container.

MXF container and re-packed that back into an MPEG TS container. Why?.because I have extracted the H.264 video out of the. These MPEG toolset differences and Long GOP structure difference don't seem to be enough to make any difference in the Vegas playback. MXF container) seems to have an OPEN or adustable / sliding GOP structure. mp4 container) has a FIXED or static GOP structure. There is one other thing XAVC-S (H.264 in the. It’s 4:2:0 color space in UHD (the broadcast 4K) and 4:2:2 color space in 1080p resolutions. Nino asked Claus about XAVC-L, which is an interframe codec (as opposed to XAVC-I, which is intraframe), with the FS5 being the first camera using XAVC-L as its exclusive codec. MXF).Īfter doing some re-packing analysis, I can see that the H.264 on the XAVC-L does have an MPEG tool called 'quantization matrix' enabled that the XAVC-S does NOT have turned on. A big junk of the interview was dedicated to learn about XAVC. The biggest difference between them is they are packed into completely different containers. Both have CABAC enabled for entropy encoding. XAVC-S and XAVC-L are almost the exact same H.264 CODEC, level and profile. I've never looked at XAVC-L but I suspect it might be similar to XAVC-S with regards to CABAC while releasing some other restrictions XAVC-S has. XAVC-S always has CABAC on but runs with lower bitrates than XAVC-I. Some encoders might not have a check option for CABAC and with this you select CAVLC. With the AVC/H.264 codec, if you want a lower decode overhead then the file must be encoded with CABAC off. Generally speaking the higher the bitrate the more work to decode.
