512 Kbits / 8 bitsperbyte = streaming 64 KBytes per sec = 3840 KBytes
per minute = (3840 / 1024) 3.75 MBytes

Wouldn't it be kbps x total running time in seconds? So if it's 512
kbps for 100 seconds then it's 512 x 100 = 51,200 kb.

Hi all,
Just wondering if there is a good way to estimate flash video file
sizes?
For example, lets say I have 2:30 of RAW DV footage that I want to
convert
to:
* Video Codec: On2 VP6
* Encoding: 2-Pass VBR
* Resolution: 480x360 pixels
* Frame Rate: 30 fps
* Video Data Rate: 464 kbps
* Audio Data Rate: 48 kbps
* Total Data Rate: 512 kbps
* Keyframe: Every 6 seconds
Is there a mathematical way to calculate/approximate file size based on
(above) settings?
My rough estimate: 9.5 to 13.5 megabytes
Sound right to you?
Unfortunately, I do not have access to the/any video at the moment... I
would prefer to just test some real video, rather than bothering all of
you folks. :(
Tips on how I could roughly estimate file size would be great! Or,
does my
guestimation sound close?
Thanks!
Cheers,
Micky
