wmv

i need the post transcoding to do a wmv at a bitrate anywhere from 500 to 1.5 and for it to be 320x240 this will fit my new zune. i can do it manually with other software but i want it automated, thanks

I'm fairly sure the zune requires newer WMV codecs (greater than WMV7). The built in ffmpeg-based transcoding is not able to produce files compatible with this.

Hi Sub,

GBPVRConvert.exe produces a WMV file that can be understood by zune, however I think the audio codec is off. I'm still learning this stuff, but by far the best results I've had so far were to use this program & then allow zune to convert it on a second pass.

I believe Zune wants wma audio, any chance gbpvrconvert is encoding in something different?

The secondary convert in Zune's software is annoying, running GBPVRConvert <source> <dest> WMV works well, it's just time consuming.

Sorry if I'm not being specific enough, this is pretty close to greek for me. I'm just parroting what I've researched. (And hopefully not making a complete fool out of myself.)

Cheers!

GBPVRConvert isnt actually developed or supported anymore. Its hasnt been used for doing file conversion in GB-PVR for a long time - about a year I think. The only reason its still included in the distribution is for remuxing .dvr-ms file to .mpg files.

That figures lol.

I have gotten ffmpeg to work, but it's not terribly "clean". I suspect it's just because I only know enough to be dangerous in Google.

I can post some command line args I found that at least get an image & sound down to the Zune if anyone wants to look. The video is way noisey but the audio turned out okay.

Maybe it's just something dumb I'm doing, everything I can find is actually for the iPod.

Sometime around 4 EST I can post what I found.

Cheers!

yes, please post the command line you're using.

I thought I had one working for wmv, but all I can find on this system is an mp4 conversion:

ffmpeg -vcodec xvid -b 300 -qmin 3 -qmax 5 -bufsize 4096 -g 300 -acodec aac -ab 96 -i source.mpg -s 320x240 -aspect 4:3 destination.mp4

The Zune software can then recongize it enough to convert what it doesn't like into a playable format.

The Family Guy I converted wasn't terrible in the first 2 minutes I had time to watch. I'm converting a Battlestar Gallactica capture for comparison to the GBPVRConvert version of the same. Noisey & there's definately room for improvement.

If anyone wants to give me some pointers, I'd hugely appreciate it. I was up until 3am to get this far lol.

Cheers!

I used to use the Windows Media Encoder SDK (http://www.microsoft.com/windows/windows...fault.mspx) to convert .mpg to .wmv in postprocessing.bat, using the command line script. from the page above,

Windows Media Video 9 Advanced Profile Update Beta
This package will update the Windows Media Format SDK with the latest Windows Media Video 9 Advanced Profile codec that is in alignment with the final SMPTE VC-1 standard. This allows applications such as Windows Media Encoder 9 Series to create VC-1 Advanced Profile content. The package also includes an update to the Windows Media Encoder 9 Series command-line encoder script (wmcmd.vbs) that adds support for Advanced Profile.

The Advance profile should let you select your resolution and bitrate.

Okay the Battlestar Gallactica episode just finished encoding & it's acutally not bad at all. It takes a bit with ffmeg and zune converts out what ever I'm doing wrong....

I'll look into the media encoder sdk, thanks!

Cheers!

ok so as of now there is no way to have gb pvr auto convert into the zune format. i tried the Windows Media Encoder but i says cannot convert 2nd pass encoding on a captured source. any clue on that one?
