photo jpeg as a video codec

where I work, the media library (roughly a few thousand movie clips) are all conformed too ntsc photo jpegs. Can anybody tell me the pros and cons of photo jpeg as a video codec? It seems rather random to me.

thanks

Well, jpeg is a known picture format, and it’s usually able to to acheive a 10:1 ratio. With the ability to allow the user to chose between a mix of Quality vs size.

Though for clips wouldn’t apng work a bit better?

It allows for quality along with video to remain video other than video turned into pictures.

IE I could have a video of the John F. Kennedy Assassination as apng so it would be decent quality and a video format that is compatible with most browsers and operating systems that can open a standard .png file.

Or, I could have it in pictures which would be scrolled across. This would be .jpg (Jpeg).

Seems most would go for the .apng. As it’s video.

That’s the pros and cons.

jpeg = picture format and not video. And it has great quality but as you raise said quality you also gain in size.

It’s fast.
It won’t compress as well as codecs that use interframe compression (like MPEG) because each frame is JPEG-compressed independently of the previous and next frame.

I kind of agree that even for archiving, this may not be the best choice.

If you use QuickTime Pro, be sure to set quality to best. The default quality setting is medium, which is plain awful.

One last benefit is starting with Windows 7, you won’t need to download any extras to play it. It’ll play in Windows Media Player 12 without additional plugins.
