From the mind of CJ Miller ...

Apple QuickTime is not a compression format, it is an open media framework supporting hundreds of codecs including mpeg, sorenson, and others designed for small file sizes. Unlike other media players, It also supports full bandwidth uncompressed files, for applications where preserving the original pixels is more important than file size. QuickTime is absolutely the most flexible, feature rich, and powerful authoring format available.

I opened one of the movies from the Eyemodule gallery in QuickTime Player and compressed it using the sorenson codec that is included for free with QuickTime. The file went from 3.5 mg to 300 K with a barely noticeable visual change. Then I made another version choosing a lower data rate and resulting in a file of 100 K with slightly more obvious compression artifacts. The important point here is that I chose whatever tradeoff between file size and visual quality that I want.

QuickTime is one of the key reasons I'm going to buy the Eyemodule2, as I don't want the camera making the compression choices for me.

Come on CJ, investigate the technology before you release any more pearls of wisdom that use crappy information.

Once again, you are wrong. The movies stored on the Visor are in a different (probably proprietary) format which are then converted to "raw" video during a hotsync. Going back in this thread you will notice that a 5 sec clip takes up only 1.1 MB of Visor memory. This is roughly 1/3 of the size of the uncompressed files. Even if the E2 converted the Visor files to MPEG on hotsync, they would still take up 1.1 MB of Visor memory.

You're right, maybe next time I'll refrain from talking about Apple technology, considering there isn't much to talk about. Maybe someday that company will get ahead, without help from Microsoft.

Yawn, an Apple v. Windoze flame war. Been there, done that. Actually, finding out that Eyemodule 2 uses QuickTime has bumped this from "Really Neat" to "OMG!, Me Want!!!!" status. The possibilities of Quicktime are endless, and combine that with the multimedia/movie capabilities built into EVERY new Mac makes for infinite ways to combine the images from an Eyemodule. And as for tech, I propose a test. I'll make a movie using the free movie creation software a Mac comes with and you make one with the free movie creation software your WIntel box comes with. Oh, wait.

Does anyone know if it's possible to use the EM as a webcam when pluged in the craddle ?
Would it even be possible ?

quicktime

in my experience quicktime & mpeg encoded movies of similar resolution, etc. are similar in resultant file size.


As an added note, however, quicktime clips seem to be of higher video quality than those produced by other encoding systems/codecs.

Cool Idea! The USB port should easily be able to handle the 640x480 stream going through it. Now we only need to have somebody come out with the pseudo conduit and drivers (that's the hard part)

I got my Eyemodule2 this weekend and posted some pictures (courtesy of iTools - this has to be the easiest way to make an album). The url is:

Thanks, Ken! I've been waiting for a glimpse of some non-showcase photos, and I'm still pretty impressed - it looks like em2 still has a little bit of trouble capturing high-contrast images (like http://homepage.mac.com/kepstein/.P..._08_41_10AM.jpg, but 640x480 will give Photoshop a lot more pixels to push around for adjustment. The sunset shots with the blue snow in the foreground are great.

How are the pics indoor in low lighting?

Hi ToolkiT,

Low light pics aren't too good. There's a lot of artifacts. I just took this one that shows the distortion.

BUT, it does do colors well..

talk about artifacts, that '7' is just a '2' upside down, the weirdest artifact I've ever seen
