That's an entirely seperate problem (ratecontrol) that should be
resolved. You are NOT getting better quality with more key frames, in
this case, just a higher bitrate for no gain.

He says lots of things that are inaccurate...

MPEG compression is not "quite bad, a thing from the past."

FLV is not competitive with "WMV and MP4."

"ON2 VP6" is not competitive with "H.264."

With lossy video encoding, 4X the resolution does not require a bitrate
"about 4 times as large." 

He also gives no reasons for using such a high number of keyframes.
