CLI to WMV/VC1? (WMV3)

[RogerTango]

What is a good CLI to encode from AVS script to a WMV with WMV3 video and WMA2 audio, VC-1 format, please?

I want to write a proggie to frontend this encoder to generate Creative Zen compliant videos.

Ive use NIC's WMVEnc with great success, but it has (to the best of my knowledge) no CLI interface.

Thanks,
Andrew

Thanks Fresh-
Question though... Can I launch WME from a batch file with command line arguments, or do I *need* the VBS that is included with the script??

Also, is this the only CLI option I have to do WMV? (From the looks of Google, appears so...)

Thanks,
Andrew

I think WME's batch implementation is exactly what you'd be downloading from Doom9. Zambelli (author of the VBS script) works for Micros0ft.

Also, depending on how many cores your PC proc has, this hotfix might need to be applied

you could run it from a batch file like this:

Transcode_2_WMV.bat

for %%a in ("*.avs") do cscript WMCmd.vbs -input "%%a" -output "%%~na.wmv"


I don't transcode anything to WMV format, but FFmpeg might support your requirements as well.

Thanks again for good follow up info.

But now I wonder, how does a program like Any Video Converter generate wmv3 files, if there not launching WME, you know what I mean?

Pondering minds want to know! HA HA!

It's probably making a DLL call to the WMV transcoder found in Windows Media 10 or 11.

I sure wish I knew more about that! I even wish I could contact the author of Nic's WMVEnc and request CLI be added to his great & nifty proggy (hint hint).

I sent "Nic" an email asking about the possibility of adding CLI support to his WMVEnc.


I never got a reply, so I guess that will remain a dream.

I like Nic's encoder as well, but the lack of any batch file processing means that I have to fall back to good old .BAT files.

Here's a rundown of the commands for WM encoder.

Thanks for the post 2360- I was looking for the CLI arguments to WME!

I contacted him (Nic) and requested adding CLI support, he says hes not doing anything else to it. Its such a shame he didnt have the foresight to add CLI argument support to the program when he first wrote it, that would have made it PERFECT!

To whom this may interest, a Doom9er named TinTime has managed to improve
Nic's AVS2ASF (which should be actually renamed to "WMV9ENC" or something).

Warning: MS regards VC-1 as just an improved type of WMV, which means,
it's not easy to make the VC-1 encoders from Microsoft produce an output
without dropped/duplicate frames. SFAIK, this is possible only if you use
the VB script written by Zambelli, with the 2-pass unconstrained VBR mode,
and without B-frames. Ben Waggoner, a Doom9 moderator who also
works @ Microsoft, has said, things will be different if you use Expression Encoder,
but I do not believe him (and no, I will not give a try to Expression Encoder, thanks).
