[Flashcoders] Recommended encoding rates for FLV?

[Reuben Stanton]

I'm after some recommendations for encoding FLV files - we'll be
delivering for two connections speeds - 256k and 1mb, in a you-tube
style interface.

What would the list recommend as the ideal kbps, audio data rate,
codec ect? I'm pretty new to flash video.

I have been using video in Flash since it was first introduced. So I will tell you what I know from my experience. I agree with Bjorn. The website he suggests is a great resource. I will also point you to a website that allows you to make a side by side comparison of codecs and bitrates. http://www.flashvideofaq.com/
IMHO, the On2 Flix Flash8 encoding solution will give you the best quality. If you have a lot of videos, then you will definitely want Sorenson Squeeze with the On2 codec plug in.

For a connection speed of 1mb I would recommend 872 kbps bit rate for the video and for the audio 44100Hz sampling rate and 128kbps bit rate. Video size 720w 480h or less. Encode with 2pass VBR for progressive download or 2pass CBR for streaming.

The quality of the source video will have the greatest impact on the quality of the output video more than codecs or bitrates. So focus on that as much as you can.

Cheers,

Craig Clark

Clark et al,

Are there any commercial enterprise level transcoders that can product
acceptible FLV files from DV or MPG2 files? I have a TV station wanting to
build a searchable interface to a video archive. What's my best bet for
automating that?

Check out FFMPEG and On2 Flix Encoder.

Sean,

Thanks - I'll look into those.

Sorenson Squeeze allows you to have a watch folder that will transcode
any video that is put into that folder. So Squeeze is a good solution
for you if you will be transcoding a large amount of video files.

It handles the main file types like DV and mpeg2. It also will capture
video from a DV camcorder.

Thanks, that was very helpful.
