Which Bitrate/Conversation Settings you use?

Hello!

I try to get a good quality for my videos. I set the bitrate to 700. Do you think that it is ok?

What do you think about this: viewtopic.php?f=3&t=722
That don´t worked for me. I got an error.

I have a 7mb wmv video, converted with 700 I get 20MB!!!

Is there no opportunity to detect the bitrate and if the bitrate is lower than the 700 the converter uses only the lower bitrate? That would be great.

That's not really how the encoder works. All video encoders (whether you use ffmpeg or mencoder) detect the bit rate as well as the audio rate, the file type, etc. The behavior that you experienced is normal for conversions from WMV to Flash as for one, WMV uses a completely different compression algorithm than does Flash and two, vShare is setup to only do 1-pass encoding. Increasing or decreasing the bitrate doesn't really make a huge difference unless you start to change more of the options. I would search Google for some good mencoder (or ffmpeg if you are using that) settings to convert to Flash. There are hundreds of them out there. Lastly, one thing to note is that if you want really good quality out of Flash Video, you should be looking at possibly using 2-pass settings and have your server do a bit rate detection and adjust the bitrate according to the original video's quality. This will yield you the highest quality with the smallest possible file size. This is exactly how sites like YouTube do it (for their Flash Video).

Hi,

but I don´t know how to realize the dynamic bitrate detection.

Doesn´t had another guy this Idea before me?
I started to convert a video yesterday evening, now it is converted. It had 400MB, now it are 95MB. That is good. I have only the problem with the small videos. I will see at which time my 250GB are full. I think they will last a long time.
