How can you idenify a rip as 480p or 520p

[cowboyup910]

I got a file, with a custom resolution of 816 x 352. Is there some way to tell, some people say its more than a 480p resolution. Is there a formula to best describes files with a customer resolution like this one.

It's 352p. Or just say it's 816x352. In all likelihood it was made from a DVD. A 2.35:1 movie on a 16:9 DVD.

Thanks, cause I've seen some other sizes like 1024 x 432, and its classified as 576p. I was wondering how people figure that out.

It sounds like some people just look at the second figure 352.


The image above, the original file before encoded was a bluray file, 1280 X 544.

Because that's what you get when starting with a PAL DVD, resize it to 1024x576, and then remove the black bars.

Not likely since that's not a valid Blu-Ray resolution. Someone had already reencoded the Blu-Ray to 1280x544 before someone else took that as a source to reencode it yet again.

It's not a rip -- it's been re-encoded.
A "rip" would suggest it's unaltered as it existed on a disc.
