Reducing file size with Quicktime Pro

I have a short video I shot with my digital camera. I would like to share the video on YouTube, but the size exceeds the 100mb max. How do I go about reducing the size? I would like to try and keep it as close to 100 as possible to keep the quality as good as I can. I thought I had it reduced, but ended up with no audio. Obviously I did something wrong.

Hi Robert,
The easiest way to reduce and control video size in quicktime pro, is to go to file/export and In the export field, select Movie to QuickTime movie. Click on options and this will take you to the movie setting. Under video there is the three tabs, first one being settings.
In settings you can choose your compression type and in theory from here you can reduce the frame rate to make the file size smaller.
The one you should be interested in is compressor where you can reduce the quality from high to low.
You can also reduce the frame size under the button that says size.
You have a choice of presets, but you can use the custom to make your own size but make sure that the frame size you select is consistent with your video’s aspect ratio.

To get it close to 100Mb size I'm afraid frame size and file size is generally found by trial and error.
Unless someone else knows better.
Good luck.

Please post the information of the video you your trying to compress... dimension, length...

Youtube steps very hard on a video when they compress it.

The size of a Youtube video is 320x240. And the audio is mono. I usually use ACC, mono, Rate 32.000 kHz, Bit Rate 48 kbps.

It makes it easier to know what you compressing to give you an answer. (or close to it)
