Is there a method of converting WMV9 in WMV to WMV9 in AVI?

[SeeMoreDigital]

Hi guys,

Is it possible to use GraphEdit (or something else) to re-encode WMV9 in WMV to WMV9 in AVI?

Currently I'm only interested at converting the video stream!

If so, can somebody provide a graph please?


Many thanks

I didn't try this with graphedit, but Virtualdub-mpeg2 can open wmv9 files and save it as avi without recompress, although it doesn't handle vbr audio too well yet.

I actaully tried VirtualDub-MPEG2 version 1.5.10 (Build 18303/release) and got the following message: -

Which version did you try?

[Tommy Carrot]

vdub-mpeg2 1.6.11.

vdub-mpeg2 1.6.11.Oh wow!

That's just awsome... and worked so quickly too!

Thanks very much indeed :D


EDIT: And here's where to get hold of it: http://fcchandler.home.comcast.net/stable/

And many thanks to fccHandler :)

There's a much easier way. Just use Avisynth to read the WMV file and feed the .avs script to VirtualDub. The script just needs to contain a simple line:

DirectShowSource("foo.wmv", fps=29.97) # or whatever needs to go there

[Tommy Carrot]

I don't think that would be easier, actually virtualdub-mpeg2 is not too difficult to use either. :D Also, with avisynth you have to recompress the video, while virtualdub-mpeg2 can losslessly convert it to avi with direct stream copy.

Agreed.... :D

The VirtualDub-MPEG2 approach worked out just perfectly for me because I wanted to compare the playback abilities of high-def WMV9 video in AVI against WMV9 video in WMV..... in hardware :D

I tried open WMV in VirtualDub-MPEG2 1.6.11 and received this warning:

What codecs I should have to success open my WMV file?

[bond]

denise, install ffdshow, go to the compression tab of virtualdub and choose ffdshow, inside ffdshow choose the decoder tab and enable wmv1

[saad]

where can i find the technical know how of WMV9 (or just basic)??????????

[denise]

bond,thank you for giving me a useful instruction.Now that works correct for me.

when i open it i get this error any help guys.

ASF: Parse error-- Too many segments in packet at 6258 (6 expected)

Haye you tried to build DirectShow graph like:
WM ASF REader->AVI Muxer->File Writer
?

There are some problems that could be.

WMV9 can use bi directional frames but AVI format likes frames to enter with consecutive time stamps.

The second potential issue, WM video frames have not time length since WMV format allows variable frame rate. AVI format handles only constant one.

Well, nevertheless you can succeed with some WM files. Just try and have fun :)

Hi Dmitry,

One of the aspects I wanted to test was how well WMV9 with b-frames worked in AVI.... and they seem to work okay!

By-the-way does anybody know.... How come when some WMA audio streams are placed into the AVI container they are identified by GSpot as being "DivX audio"?


Cheers

[videomixer9]

prolly cause former DivX ;-) Audio was nothing else but a bitrate limitation and some others hack of Microsoft's Codecs. DivX ;-) Video was a WMV hack and DivX ;-) Audio just some hacked WMA or so ...

It might be damage in the stream. The parser in VirtualDub-MPEG2 has almost no error handling capability.

WMV9 can use bi directional frames
I've heard that too, but I haven't been able to confirm it. The only reliable info I've seen is on this page (http://www.microsoft.com/windows/windowsmedia/howto/articles/codecadvancedsettings.aspx). They confirm that the WMV9 Advanced Profile codec can use b-frames, but it requires a registry hack. (By default it doesn't use them.) So far I haven't found anything official saying that the regular WMV9 codec uses them.

So i can do anything about it

[fccHandler]

I can't say for certain without examining the file, but if it's truly damaged then there's nothing you can do to repair it. You could try to convert it with other tools like TMPGEnc, GraphEdit, or serve it with Avisynth's "DirectShowSource" command.

would you like me to send the file its just a music video size is 26MB

[BlindWanderer]

If you captured it off the internet then it likely has missing packets in the stream, which Virtualdub-mpeg2 will choke on (or thats my experience).

Hello fccHandler declared this:

Somebody can it really confirm your statements?

This has been bugging the hell out of me but is it possible to do a reencode of WMVHD file to xvid with DVD2AVIT3, avisynth and virtualdubmod?

Yes, you can, but DVD2AVI is not a need tool for this job
