FLV encoding

[Ven]

Hi guys, I really need help with VP6 or VP6A FLV encoding.
I have few dozens of videos needed to be used in Flash project.
They're 1536*1152 in frame size.

Adobe After Effects CS6 does great FLVs,
There was an option called "Simple profile", it's very good for FPS optimization and speed inside Flash.
but it's limited in height to 1080p only (and I have 1152).

I've tried old Flash Video Encoder by Macromedia (2005), quality is good, resolution is okay, but when in Flash, FPS is dropping down.

I've tried FLV1 option in avidemux, it works fast inside Flash, but codec's quality is garbage, even with all sliders maxed out.
VP6 option is missing. Is there a way to get it?

Maybe there is some other option to export FLV with simple profile, but with bigger resoultion?

I know it's all outdated and all that stuff, but still....

Another alt is to try and find Sorenson Squeeze I suppose.  It's abandoned now anyway.
