A good size of flash mp4 file on a page

[Cazz]

Hi, I trying to find what kind of size I can use that is not to small and not to big (both in file size and area.

For example, I have recording and edit a movie that is in 1920x1080.
Now I like to save it as MP4 that I can use a flash to play it on a site.
I think 1920x1080 is a little to big and was thinking use a bit smaller size,
but not to small so if someone like to see it in fullscreen on the page.

What I remember I have to divide with something.

So what is a good size of a movie that is in widescreen or not?

1280x720 is used for widescreen quite a bit.

Thanks for you replay.
Hmm ok it is maybe is still a little to big but I think I can use that size on other projekt.

How do I calculate what size if good if I have the original size?

/Update
Have a little more time to replay.

hmm what I can see with you size that is using a system

1280x720
640+640=1280
360+360=720

1920x1080
640+640+640=1920
360+360+360=1080

So i guess that 640x360 is a good size?

That 's OK
But I go low till 544x304 at 650kbps

an in between size that works for widescreen is 864x480.

How did you came up with that size?
I just wonder, like to know if that is a system

A another question.
If I want to have a file that is 4:3 and not widescreen, what is a good size then?
