VBR Encoding WMV with Sorenson
I’m using Sorenson to encode WMVs for the first time and would like to confirm I’m doing the VBR encoding correctly. I’m trying to encode the video at 7-18mbps. I chose WMV 9 Advanced as the encoder and set my data rate to 7,168kbps and the max data rate to 18,421kbps (it’s the closest I could get to 18,432kbps without going over).

Wow that’s pretty high, are you encoding 1080p?

very sorry wrong thread!

Source is 1080 output is 720. My math is right though correct? 7mbs=7168kbps
I’m compressing FLVs, 2 flavors of MPEG-2s, 2 flavors of WMVs…at lot of different needs for this project. I know with this particular WMV compression it’s going to be used for HDTVs.

To most people 7 Megabits per second = 7000 Kilobits per second.
I you want to do VBR I’d aim for a peak of 14Mb/s rather than 18

Thanks Daniel.
As for the settings in Sorenson, the “Data Rate” section…I assume when doing VBR that is the average data rate? Is there no place to set the minimum?

I don’t use Sorenson but usually you set an average and a peak, the peak is usually not more than twice the average.

Thanks again Daniel. I guess if I stop and think about it, it makes sense that the peak shouldn’t be more than twice the average.
