reducing size of movie

[sonja athene]

i managed to join 2 music videos into one.
first video is 42 mb
second video is 33 mb

my problem: after i joined them, it's 2.97 gb. it's too huge! they were first .dv file then after editing, it's .mov file which then became almost 3gb.
how can i reduce it's size? it's not supposed to be that big.

You used iMovie? Its probably in DV format, thats why its so big. One way of compressing it is to open it in Quicktime Pro, then export it to a .mov using the Sorenson 3 codec. Is the video going to be uploaded so the smalles size is much preferred? On the export setting, set to 15 frames per second, keyframe: 75. Also toggle the width and height and image quality slider.

If its just for playback on your HD, fps: 29.97 , keyframe:150 using sorenson 3 is ok.

Use Media Ceaner or a similar compression software to reduce the file size.

Or you can use the freeware FFmpegX

newbie question:

Hey guys, I have a similar question. Went to the shop today, to test drive the iMac G5, 1.6GHz, 256MB. Specifically, I brought my Sony miniDV digivideo cam to see how the iMovie interface was.

The first thing I noticed was that some clips that were only 1 min 30 seconds long took up 300 MB of space!

Why so huge?

And how is it possible that you can fit an almost an hours' worth of footage on one vcd (the 700MB commercial ones), yet 1 1/2 minutes is 300MB..

I need a primer on these things :lol: Can anyone suggest interesting, informative links?

THANKS!

in relation to the questions already asked, what are the elements of the best setting when exporting a5 to 10 minute 800x600 proj file created using Adobe Premiere in PC to be used as a video presentation (with audio) in Mac's Keynote?

The footage that comes out of your miniDV camera is in DV format. 1 min of DV footage = 200MB , so downloading 60mins of footage will consume 12gigs of HD space. This is normal because the quality is very high compared to VCDs.

VCDs on the other hand are in Mpeg-1 format. Its a very compressed/lossy format than DV, thats why you'll notice the quality is poorer. 1 min of Mpeg-1 footage = 10.1MB

Here's a very good starting point.

The best would be Quicktime .mov format. Premiere should be able to export to this. An 800x600 is an awfully big resolution, your ibook/powerbook or Keynote might not be able to handle such a big file, or it might slow the presentation down. But if you find that its ok and your mac can handle it...

If the footage has a lot still pictures, using the photojpeg codec is good at 25 frames per sec. Normally, I'd recommend 320x240 so it'll be more managble. Then you can just resize it to 800x600 without noticeable quality loss within Keynote.

Thanks for the tip Kenneth on resolution size. If the photos and the graphic elements and texts are animated in the video presentation, like zooming in and out, swiping left to right, will the photojepeg codec still be good?
