Use a compressor compress to 3G, 3G2, or MPEG-4

Thanks,

I guess each company has their own specs. Does anyone have some sample specs I can test with on My Procoder 2 Station? Or is there somewhere I can look for example delivery specs. I just want to make sure I can deliver at these specs.

Mickey,

Thank you so Much!
That's a lot of specs! Many of which I havent seen before! What software application are you using?
Are there any one can recommend?

Thanks a million!

The easiest is probably to upgrade to QuickTime Pro. QT Pro has some presets specifically for this, it's not the highest quality, that comes from a package like Xenon - http://www.vidiator.com/products/xenonEncoder.asp.

Many encoding applications rely on Quicktime for .3gp encoding. Xenon has it's own .3gp engine.

Coming straight out of FCP 5. I think the 3gp encoder comes with it because I can't recall installing it separately.

I tried encoding with other programs but the results were no better than from FCP.

Best of luck!
