NASA Wants A Higher Resolution Format. What do you recommend?
I’ve produced a 2:15(two minute 15 sec) Animation for NASA
720X480 pixels. File size needs to be reasonable (fit on CD).
Currently I’m using Mpeg 4 10fps and getting 224 Mb file size.Customer wants better resolution…
How can I get dramatically better resolution and smooth playback
on a standard PC or MAC (customer may use either but may prefer MAC)?Sorry Animation is Proprietary.
Using AE 6.0

Definatley a job for the h264 encoder. But be aware of the hardware needs for decoding. I have a 3gHz PC which stutters while playing a h264 video in 720p at 5Mbit/s. The good thing is you can go for really low bitrates with this codec.
The best playback performance has DivX in my opinion. The compression is damn good too. But as far as I know you will need separete files for PC and MAC.

Thanks…will try this.
-
What bit rate would you recommend for general playback(engineers usually don’t have clunkers)

I agree about h264, but please note that you must do the multipass (frame reeordering method) to get ultimate quality for size control And AE does NOT do this. QTPro does however. Render out AE uncompressed, then export from QTpro to h264.

Great I’ll get QT pro. Initial results with h264 in AE look promising.

Render out AE uncompressed, then export from QTpro to h264.After Effect does in fact do frame reordering when exporting H264, no need to spend extra cash on QTPro or involve an extra render/process – simply render your movie using FILE>EXPORT>QUICKTIME…. the frame reordering option is there.

Great, Just in time to cancel my order since apple screwed up the first one.

Would that be the “keyframe every ____ frames” checkbox…if so…how many should I try?

Frame reordering is not the same as Key frames.
For key frames try some high values – even as high as 50-100 on a 2 minute piece. (experiment!)
The quality of the frames between the key frames is controlled by the same slider as the compresseor quality slider – simply hover your mouse above the slider and hold down option (on a Mac) and it will change to ‘Temporal’ – set this around Low to Medium.
I also usually use MPEG4 audio to get good sound quality with little bandwidth overhead.
All these setting depend on the nature on the content you are attempting to compress – I usually stick in some known values and experiment from there if I need efficiently compressed files.
