How are you compressing your film to down 50MB?

Your frame size should be divisible by 16. Mpeg codecs use macroblock sizes of 16x16 so if you use odd sizes that don't divide into 16 you will end up with a glitch or line somewhere in your video - usually the bottom - in an effort by the encoder to fill in the missing parts of the macroblock.

14. Size> NTSC 720 x 486 4:3. If you have used widescreen, go to custom setting and put 720 x 405 (I actually prefer 720 x 404 - which is divisible by four and might just make a quality difference, don't know). If you are not satisfied with the quality you may want to try a smaller setting (in proportion of course)

Zim,

I shoot 24pA SQUEEZE on the DVX.

When I export that type of footage, I export the size as 854 x 480. Not 720 x 404.

854 x 480 makes it bigger. Is 720 x 404 a setting you use for TRUE widescreen?

Cause I know the DVX, 16:9, SQUEEZE mode isn't really "true" widescreen.

I was having all types of problems getting it right. I finally de-interlaced the footage and used some crazy size And it came out really nice. then i missed something in the edit and had to export again and forgot what settings i used. it took like 5 hours to get it right again. But its right dammit :) compression is an artform in itself.
 
I'm using Adobe Premiere Pro, and can't seem to figure out how to export this properly. I've tried quick time at h.264, and it's still about half a gig. Are all the videos going to be like 320x240 or something? Because I seem to remember them being larger when I watched the time fest entries. Bottom line, please help. I'd hate to not be able to submit my film because of my technological confusion.

Get QT Pro and follow the steps in this thread. It's only $20 or $30 bucks and it works!:thumbup:

Good point. I don't know.
How small have you managed to make it? Can you get it under 500MB?

If you can upload it to Vimeo (make it private) and check the option to allow someone (who knows the password) to download the high quality version... I would be happy to compress it for you.

There's probably another way though. Still, I would be happy to do it.

If it gets to that point, I will keep this in mind. Thanks a lot.

Use H.264 and calculate your required bitrate based on the length of the film. You can always get the filesize down to what you need.

Example:

50 megabytes = 51,200 kilobytes
4 minute film = 240 seconds

51,200 / 240 = 213.3 kilobytes per second for video and audio

If you're using 96 kilobytes in your audio stream (use aac 96kb) leaves you with 117 kilobytes per second for video.

Don't forget to look at the resize frame options and choose the best quality options for scaling if you're changing from your native resolution. Also consider dropping the frame rate too?

Actually the audio stream should be 96kbit/s, not kbyte/s. That are 12kbyte. So of those 213.3kilobytes are 201.3 kilobytes for video and 12 kilobytes for Audio.

But talking in kilobytes is kinda unfortunate, because the preferences are always in kbit/s.

Ok, to clear things up a bit, here an example for a 6 minute film:

50 megabytes = 51,200 kilobytes = 409,600kbit
6 minute film = 360 seconds

409,600 / 360 = 1137,78 kilobit per second (kbit/s) for video and audio.

If you're using 96 kbit/s in your audio stream (use aac 96kb) leaves you with 1041kbit/s kilobytes per second for video.

So the 970kbit/s for video suggested from jason actually make sense :) It could even be a little bit more (depending on you audio settings), but with this value you are safe!

Anyone know what the best way to export and compress via Adobe Premiere Pro CS3? I exported as Microsoft AVI but the compression was horrible and the aspect ration was wrong. I shot 720 24PN but it looks squeezed.

Anyone have any good suggestions on how to export out of Adobe? I can use Quicktime pro to compress down to a sub 50mb .h264 file I just need to get something good before that step.

Sorry, I've had nothing but trouble. You can read about it if you're interested here: http://www.dvxuser.com/V6/showthread.php?t=150745
