1080p vs 720p and what is this fps

[Ryvannis]

I'm a bit confused here. MKV is a container. So under my assumption, wouldn't H264 be a video stream contained with MP4 at the lossless level? My concern here is that I'm running into somewhat of a similar situation with Blu-Ray rips. I figured a 2 pass rip conversion net me something of lossless quality if the bit rate is high enough?

Would net me something of lossless quality. Correction on my part.

The OP isn't talking about remuxing, just re-encoding. As to your question, a 2 pass encode will always be lossy unless you do it lossless, in which case why bother with 2 pass at all? To get lossy codec bitrate high enough to be almost identical, the filesize is larger than just doing it losslessly in the first place.
