Hi All,
if you want to convert WMVHD files into AVI to edit them in your
Video editor program you can use an almost realtime conversion
process.

For instance download the Speed_720p.wmv file from the
www.wmvhd.com site and drag it into graphedit.
Then cut out the directhow Audio renderer and the Videorenderer
at the end and insert a videocodec like
DIVX, HUFFYUV or XVID Codec and the AVI muxer and the File writer.
Now connect the output of the wmv decompressor to the videocodec and
the output of the codec then to the first input of the AVI muxer.
Take the output of the WMV audio decompressor to the other input of the AVI muxer. Now connect the output of the AVI muxer to the filewriter and then press the play button.
On my 3.2 Ghz P4 laptop the AVI file in 1280x720p res is
rendered almost in realtime this way.

If you want to set the compression for the videocodec you have to
open up Virtual Dub first , load any other AVI file and set the
compression setting for the codec you want to use inside Graphedit.
As you close then Virtualdub, the same setings for the codec will
be used in Graphedit.

Question: Is there a simpler solution to set the codec parameters
directly inside Graphedit ?
Is there anywhere a Graphedit FAQ ?

Anyway, this is the fastest way to convert a WMVHD file almost in realtime to AVI, so you can use it to edit it in a video editor
later on.
You can also directly edit the WMVHD file although in Ulead Mediastudio Pro 7.x. That works also.
This all only works with NO DRM protected WMV files !

Is there any simular simple solution for DRM protected files ?

Thanks.

Regards, harti.

if i understand your method right you simply reencode the .wmv. if yes, than this is nothing new
what would be interesting would be lossless wmv->avi (or any other container) method

what damrod meant was that you could also pass the file through with avisynth (via directshowsource), which would also allow resizing, etc... and opening of the file in virtualdub directly for example

If you cut off all of the decoders and renderers and drag the sreams into the AVI Muxer, then there is no reencoding, just remuxing

I've done that for months now, but used Matroska instead of AVI, cause it's cooler.

you make an avs file via directshowsource

then open it in virtualdub and save as no-compressed avi file ;-))

of you use avisynth 2.54 you have both video and audio stream...

directshowsource sucks!!!

for realmedia it is the only way, but when there are vfw decompressors for any codec, it is better just to remux everything into another container and open that, since you now can cut it and remux it without recompressing. And even if you want recompressing, it is still better to use just the remuxing method, since then you will never lose that 1 frame at the end.
