I have many SD projects in Final cut pro, that I need to convert to .flv with some very specific settings:

Constant Bit Rate
VP6 codec
progressive downloading, not streaming
data rate of 400 kb/s
audio compression of 64 kb/s

What Mac program would you recommend for this? ffmpeg? Flash? Something else? I don't have much time and I'd like to know what works best.

Thanks!

I like using After Effects CS. It did the best job of all I tried.

Sorensen Squeeze with the professional codec plug-in works well.

I don't think they are the same. I couldn't get the Flash encoder to look good at all. After Effects uses a version of the On2 encoder I think.

After Effects it is then, thanks

I use On2 Flix Pro and Flix Exporter. You can purchase these from On2.com. Flix Pro is a standalone app, and Flix Exporter is a plug-in you can add to QT Pro, which gives you the export functionality of Flix Pro as export options from QT Pro.

I recently purchased Sorenson Squeeze, which I understand will be able to use my On2 installation to add VP6 export options to the Squeeze Suite, but I haven't tried that yet.

I did a lot of reading up on this some time ago, and read a detailed demo and review comparing the output quality between the On2 product and the options provided through the Adobe applications. I don't remember where I read it or what the link would be, but I do remember the end result stated that although there are a few advantages in some instances of the Adobe options, the better quality was generally achieved using the On2 Flix product. I am not sure if this was due to 2-pass options or something else because I can't remember what the limitations of the Adobe After Effects or Flash output were.

This is not the review I noted in the above post, but it does give more information than I was able to give.
