I'm new to the flash world (am an FCP editor by trade). Our company just started a blog and I am the one in charge of encoding and streaming the video. I'm using On2 technologies (the pro version) to do the encoding. I'm on a mac and the settings seem different than the little tutorial video on their website.
Anyone care to share the optimal settings for flash video? Mine tend to be around 4 min. each and I would like them to look really good. :)
The best quality that I've seen with VP6 codec is to export a Quicktime Conversion H.264 codec in FCP at the highest setting possible. Encode your FLV using the a frame rate of 15 and 512K streaming, deinterlace the video, but not in quicktime, you really want the encoder to do all the work. What are you using to encode your video's with? I usually set my video rate at 289k and audio at 16k mono. I find that my video quality is still good and I don't really have a need for audio that needs to be stereo, since most of our clients watch from a desktop or in a shop. I hope this helps, but i too, am also still trying to get the settings nailed down. let me know if it works or not.
When I export from FCP I export a Quicktime file with the 720X480 frame size and between 1000k and 2000k with the H.264 codec. Then using my encoder I encode using the VP6 with a stream rate of 289k and 16k for audio, deinterlace and a fram size of either 320X240 or 640X480.
