I have been using Any video converter(if you think that there is a better converter please advise) to convert some of the video files I downloaded to mp4. I am having a few questions of converting wmv files. It seems that all the wmv files involve VBR with video and or audio. I checked the file with mediainfo and pasted one result below. Overall bit rate : 2 126 Kbps Maximum Overall bit rate : 2 104 Kbps Encoded date : UTC 2011-06-01 20:28:55.000 Video ID : 1 Format : VC-1 Format profile : MP Codec ID : WMV3 Codec ID/Info : Windows Media Video 9 Codec ID/Hint : WMV3 Description of the codec : Windows Media Video 9 - 2-pass VBR Duration : 16mn 46s Bit rate : 2 048 Kbps Width : 960 pixels Height : 540 pixels Display aspect ratio : 16:9 Frame rate : 29.970 fps Bit depth : 8 bits Scan type : Progressive Compression mode : Lossy Bits/(Pixel*Frame) : 0.132 Stream size : 246 MiB (96%) Audio ID : 2 Format : WMA Format version : Version 2 Codec ID : 161 Codec ID/Info : Windows Media Audio Description of the codec : Windows Media Audio 9 - 44 kHz, stereo VBR Duration : 16mn 46s Bit rate : 41.2 Kbps Channel(s) : 2 channels Sampling rate : 44.1 KHz Bit depth : 16 bits Stream size : 4.94 MiB (2%) Is there a way to convert vbr to cbr or is it best to keep it at vbr but in different format? What does it mean that vbr is Q85 or Q90? I am a newbie to this so I do not know much about various bit rate formats. I have been usually setting the video and audio bitrates to the ones I found in the original properties of the file. I became somewhat worried cause in some of the wmv files it said that audio bit rate was 0 kbps. I wanted clarification on what to do if the file that is being converted from uses VBR instead of CBR.
