Best methods for exporting a .mov from Flash?

I’m creating an introductory video for readers of my webcomic. Because I know Flash, I’m creating it there. Basically it’s a voiceover with some static comic images getting panned and zoomed around, with some sound effects and such.

They key thing is that I want this to be easily shared. The best way for that (I think - open to other opinions) is to get the final file uploaded to YouTube and saved as a YouTube video, which I then embed on my site. YT vids are extremely easy to share and email around. This gives me the best option for getting the most eyeballs on it.

The problem I have had in the past is that exporting a Flash file to .mov makes a MASSIVE file, size-wise. This video will be like 3 minutes long, I’m a little worried that the file size might be too big to upload to YT. Also, in general the exported .mov looks like garbage compared to the SWF.

I know you can modify the Quicktime compression settings and such when exporting, but I am not sure what the optimal settings are.

What are your thoughts? Looking for any good advice…
