Increasing max bitrate for encodes?

Postby navstar » 19 Feb 2010 23:08

I'm trying to encode a 1600x1200 Quicktime with audio into a muxed MPEG-2 transport streams. The max bitrate of 3000kbps is just too low for a movie of that size. How can I tell it to have a higher data rate (>10Mbps)

You can easily do this with command-line transcodes. The bitrates in the UI are just random values. Create your command with the streaming wizard and adapt the values accordingly to easily control VLC with Terminal.app.

I've never used Terminal before. Can you give me some pointers on how to do that?

Well, basically, Terminal.app is an ordinary terminal emulator running bash by default, so the syntax is similar to what you'd expect from any UNIX-like OS.

Anyway, use cd to navigate to the Applications folder or just drop your VLC.app in the terminal's window to get the respective path. Then, run VLC in Contents/MacOS with ./VLC and the options mentioned in the previous post along with the path of your input file.
For more information on VLC's command-line options have a look at "./VLC --longhelp --advanced". For syntax help with bash, there should be plenty of information available on the net.

Please be aware that you cannot wreck your OS with the basic usage rights you got when starting Terminal.app. You can just do what you can do with the graphical interface, so don't be afraid.

It would be great in the next version that you would allow users just to type in a number in the Wizard rather than choose from a list of (non-HD) bitrates.

Definitely. I'll see if I find the time to add this.
