What software are you using to create your FLVs? I know Sorenson Squeeze has
a setting that allows you to specify a minimum quality level which overrides
any data rate settings (if/when it needs to). So if you set your bit rate
really low, like 50kbps but the minimum quality is set to 95, you'll get a
huge file.

Subject: [Flashcoders] Flash Video : Relationship between data rate
and file size doesn't work ?
To: [email protected]
I don't know if I'm missing something here but what's
the deal with Flash Video data rate and file size?
Here's my understanding on Flash Video encoding:
When I specify 300 kilobits/second for the video data
rate and 50 kilobits/second for the audio data rate, I
should get and FLV file that NEVER goes beyond 350
kilobits/second.
So if I encode a 30 second video with those settings,
I should get and FLV file that weighs 1.28 MegaByte.
If I decide to double the frame size for exemple (from
320x240 to 640x480), I should still get the same file
size (1.28 MegaByte) but the image quality should
obviously be badly affected.
That's not the case.
Can someone please help me shed some light on this
data rate vs. file size dilemma?
