How come there are DivX logos in videos

How come there are DivX logos most of the amvs? I was just wondering that. Like where do they get their clips?

The clips they use to make the movie are DivX encoded, and that watermark is placed on the video.

What is what? DivX or encoding?

DivX: A form of encoding
Encoding: The way that data that makes up a video is set up (in easy terms).

In other words, if you play back a divx video, the divx program (which decodes the video) puts a small logo on the video for a couple of seconds.

These people use divx videos to cut up and make their own videos, so when the the editing program plays the original divx videos (to itself, to create the new video), it calls on the divx program to decode the video, which puts the divx logo on every small clip it's asked to decode (only for a couple seconds, but that's usually the length of the clip).

An obligatory note: Using divx videos as source material is very bad (and you can at least turn off the divx logo in the settings of the divx program).

Wrong conclusion! Depending on how it appears during playback you can tell if they used DivX encoded clips or encoded it with DivX as they exported their vid and haven't turned of the logo. But you can't make a general conclusion. It happened to me as I exported the first time my vid which was made from DVD source. And it needed a while to figure out how to switch it off.

Ah yes, I forgot about that possibility. In fact, you can have two divx logo's.

I use the ffdshow decoder here, though, so if I see the logo, the conclusion's obvious.

How do u get a decoder? Can it rip dvds?

Most codecs offer the decoding portion of their code for free from a million an one sources off the net. For codecs like Divx, just check their site. There is a direct link to download the decoder. For codecs such as Xvid, the source code is easy to find if u want to compile your own binary, or many good folks like Kopei make pre-complied versions also available on their sites. They are easy to get, just use that wonderful google tool.

As for if they can rip dvd's... no, no they cant. Codecs are simply algorythms that compress/decompress the video stream. Codecs such as Divx and Xvid (to name the 2 most popular) are esentially tools to shrink a file down after ure done authoring it. To actually rip a dvd, u need a program that is specific to that task.
