Query about bitrate and bluray terms?

[Kaiju]

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, for anyone experienced in the field, I want to change the resolution of a bluray rip I made 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 a program called 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.

Yeah, it clicked this morning. It's not about bitrate, it's about resolution.

Thanks for clarifying.

On that note, is it trail and error when ripping a bluray disc to get a bitrate best suited so it doesn't allow artifacts, blocking or stuttering?

dbmzk1 - Thanks for the heads up.

I just re-encoded a 16000kb bitrate rip so I could rescale and change the font. Even though the bitrate is the same as the original, there is definitely a noticeable change in quality, at least up close.

There seems to be less grain on the screen, which i'm guessing is due to the fact that everytime you reencode something (instead of a lossless format), the quality will diminish.

kylew - On a 32" TV, the upscaling isn't as noticeable as my other 46" TV. Therefore, I prefer fullscreen on the 32".

Seft - Cheers bro, i'm only starting to figure this all out.

Last night I was playing with Mencoder (PS3 Media Server) and figured out how to change the subitles, AT LAST! I used some simple parameters to force the font change for the .ASS file. Mencoder also has a video upscaler option, so I changed the height and width parameters, but it didn't scale. That is my next challenge tonight! I will give FFDShow a whirl.

Thanks again guys, i'm stiill figuring out all the noob stuff.

Corasik - It honestly doesn't feel like matchstick men when I watch it fullscreen. I've tried to adjust to letterbox for what, 10+ years now and it's like squinting unless, of course, I use my 46" TV.

Trouble is, my 32" TV is in my bedroom and I simply would like to watch it fullscreen on that sometimes. Again, I do not doubt letterbox is the way it should be watched, it's just my preference.

Seft - No, no, you are quite right, i've found that i've encoded, re-encoded and then re-encoded some more purely because I'm delving in with limited knowledge and don't know what options I have at my disposal. There has to be a learning curve though or how am I supposed to learn without hands on?

Thanks for the heads up about the grain. 300 loves the grain.

Thanks Schizophonic.

I already had taken that into account as I only have a 2.1 Z-2300 set in my room. I simply use Nero's AAC Encoder @ 320kbps and it does the trick.

Again, this is all for my bedroom mind.

I've found threads transferring DTS across an encoding, it seems like there is a workaround, so i'll give it a shot sometime.

I've given up re-encoding a rip for now, at least until i've got more knowledge on the subject.
