5 minute Quicktime to compress under 20 megs?

[Rj Miles]

Have you tried…

reducing frame rate to 15fps
altering the data rate settings for audio & video

I have been able to get pretty good results at about 3MB/:30 of finished video. Good enough for client review atleast. 🙂

You can try recompressing through sorenson squeeze, but I seriously doubt you’ll be able to fit that down to 20 without some serious compression artifacts and/or loss of quality.

Try this:

Drop your frame rate down to 15fps,
Make sure your audio is AAC, and unless you have lots of fx, switch it to mono, 32khz
Use H264, low-medium setting

That might get you close….

Sorenson 3 generates much smaller files than h264.

The closest I can get is 49.5 on h264
sorenson makes it 150 megs.

WTF?

[Gordo408]

No it’s getting larger
Sorenson is about 150
at 15 fps medium to low
audio aac 44 16 bit

please the deadline is monday

Gordo,

A major factor in the file size of these is the data rate. Every preset in Squeeze or Episode has set data rates but you can change them. You also can do this from QT Pro, set you data rate as fixed at around 400kbs, use 15 FPS, set quality to medium and you will get smaller files, Quality/pixelation is the tradeoff, depending on your effects and motion, you have to tweak it till you get the right balance. For audio use IMA 4:1 at 48K. This should put a 4.5 minute show somewhere around 20 megs.

Here’s what I’d do
Make it simple this time and export from FCP using Quicktime conversion.
hit options, settings, key frames automatic, data rate automatic
frame reordering on.
quality med. faster encode single pass.
ok
size, 320 by 240
check deinterlace.
ok
sound settings
format AAC
48 k is fine
quality normal
AAC encoder setting, 128 bit.
ok
uncheck streaming if you don’t need it.
If you do, check the box and use fast start.
ok
save.
Your file should be between 15 and 20 megs, and it will look great.
Worry about using Compressor next time.

Oops, forgot the compression type, H.264.
