Size, Bitrate and Bits-per-pixel calculator thats capable of HD resolutions

[mjr4077au]

I frequently use Aspect 2.1.0 for calculating resolutions but that only goes upto 1024x768. Is there something similar that I can use for HD resolutions (1280x720+). Oddly enough I thought if I had a resolution of 512x384, doubled it to 1024x768 and also doubled the filesize, the bits-per-pixel ratio would stay the same, but it was significantly less.

every movie, clip, film, etc... has a different compressibility and each encoder will compress it with a different efficiency. so bpp is completely useless.
start learning how to do a compression test before encoding and you'll get way better results.

Someone wrote that calculator program for a reason. I don't rip movies for 100% transparency, I rip for convenience and when you have a interlaced 576-line CRT TV, it doesn't matter too much about quality.

I do understand some movies are harder to compress than others but I don't really care. The rips I do are better than and 2CD pirate i've ever seen at a similar size (not that I do any piracy :) ).

512x384 to 1024x768 is not twice as much pixels but 4 times because you double in each dimension.

Gordian Knot was originally designed as a calculator, and does go up to 1920 x 1080.

It all makes sense now. I need to go back to school :stupid:. Thanks a bunch.

I clean forgot about GK. I used to use it for XviD encodes. I'll drag it out again. I believe it's still installed. Also, Thanks a bumch.
