how to wmv+mp3?

[zackwz]

How do i combine a wmv file and a mp3 file (converted from wma in the wmv)?
I tried to convert wmv to divx+mp3, but there always seems to be heavy quality loss. If i want good quality, then the size will be huge compare to the wmv.

May as well leave it wma then. What is the point of having wmv+mp3? If you have a wmv/asf parser and wmv decoder then you are going to have a wma decoder to.

Use Virtualdub-MPEG2

You'll probably need to install WMV9 VCM but VD-MPEG2 will open WMV files. If you direct strean copy the video and compress the audio to MP3 then you'll get a WMV.avi with MP3 audio.

Another option is to drag and drop the WMV file into TMPGEnc and choose File>Output To File> Avi and choose the video and audio compression you want. WMV9 + MP3. The disadvantage of this is that you have to recode the video.

If you want it to be WMV instead of AVI after using Virtualdub-MPEG2, just change the extension back to .wmv

VirtualDub-mpeg2 works out very well. Thanks very much.

Changing the extension doesn't make it a wmv. You would need to remux using say Graphedit.

But direct stream copying a WMV would make it an AVI?

Most players don't care that a windows media player file has an AVI extension, they'll play it anyway but It's a good idea to keep all your WMV files with that extension so you don't try to play them in a DivX player that can't handle WMV.

thank fcchandler.

Direct streaming does make it an avi yes. There is WMV the container and WMV9/8/7 the video codecs. VirtualDub-MPEG2 outputs avi's, so you get WMV in an avi container.

[DarrellS]

OK, the container thing makes sense.

If you can direct stream copy a WMV into an AVI container then why couldn't you direct stream copy a QT or RM file into an AVI container if you used an avisynth script?

[celtic_druid]

AVISynth serves raw video, so if you direct stream you get raw video in an avi container. ffmpeg may be able to direct stream some of them to avi. avi relies on fourCC's to identify video streams though, so if there is no decoder with a matching fourCC available, then you wouldn't be able to decode it.

You need to be careful direct streaming stuff into an avi though since wmv, mov and rm all support VFR (Variable Frame Rate) and avi doesn't.

I really don't see the fasination of putting stuff in an avi container though.

I did one .mov file and like you said, it processed the raw file - DIB (_RGB) - BI_RGB Raw Bitmap. It did it in lightning speed but 1.5 GB is pretty big for a file that was compessed to 4.5 MB. I didn't have any RM files on my computer.

Right, that seems to be an advantage of using TEMPGEnc to convert WMV. I don't remember having sync problems when I went that rout but I have run into files with V-Dub that were troublesome.

I download alot of football clips where I'm not worried about the audio. I'd rather download everything in avi but most people either want to upload moviemaker files or youtube everything.

It's usually a temporary thing like direct stream copying a bunch of clips and then appending them together or to get a file to a smaller size for uploading to a file host. I can't view a WMV on my hosting site since I use Media Player Classic and it uses Windows Media Player inbedded but if I upload it in an AVI container, then I can view it just fine. Not sure why.
