Your FLV frame rate should be as close to the Flash frame rate as possible. The reason is the audio track in the video—it always plays back at the original frame rate. Let’s assume you create an FLV file that uses24 fps. Place that in a Flashmovie that plays back at 12 fps. The video portion will play at 12 fps, but the audio will play at 24 fps - not really what you want!
What size should the video be?
Well creating an FLV file at 720x576 is going to create a huge problem to the user with a slow connection so consequently,this is why most FLV files use:
320x240,
240x180,
160x120,
80x60.
As always you should make it your business to find out what your potential target market are likely to be viewing your creation on so that you can make an informed decision with regard to data transfer rate. Remember always keep the user in mind and adjust the technology accordingly.
I'll make it easy for you - we will be viewing them on the PCs in the labs so you are safe using 320x240.
