    So far I i've seen 1080p rips at 10mb-16mb and 720 rips from 4-8mb. Does that mean if you rip a bluray disc and set the bitrate around 4mb, it'll be classified as 720p and a bitrate of 10mb+ will be 1080p?

    Am I right in saying 1920x1080 is 1080p and 1280x720 is 720p?

    If for example I had a bluray rip at 16mb (opposed to trueHD @ 30mb+) and then re-encoded it to 4mb, would it be classified as 720p?

    Basically are 1080p and 720p just advertising terms?

    Lastly, I want to change the resolution of a bluray rip from 1920x800 to 1920x1080, effectively stretching it (yes, i know). Would I have to transcode it again or is there a faster method/shortcut of doing this? Currently it takes me around 12 hours to transcode the file using Mediacoder.

    I want to change the subtitles characteristics too as they are too big in the current mkv container. Mediacoder only allows you to hardcode the subtitles into the video. Is there another way to edit the current subs in the mkv container? Hardcoding subs effectively makes it impossible to switch the subtitles off in the future.

    Ah, it just clicked 1080p and 720p are resolutions, not bitrate.

    So you can have a 1080p file at 1920x1080 and it could be less than 1mb bitrate, but still be 1080p, albeit heavily compressed with a huge lack of quality.

    Now, If I could just get some clarification on the other part of my post.
