View Full Version : Capturing video using MPC external filters... how?

I'm trying to re-encode video files that are using a VERY old video codec with another codec. Namely Truemotion 2.0 to x264. TM is not a VFW codec, and thus I can't open it in virtualdub, nor can the avisource handler from Avisynth run it unless I enable the libvacodec in FFDshow. Then again, the con about this codec is that it doesn't allow 24-bit compression and thus the output when using Avisynth is all saturated in colour levels. And I don't want to use the directshowsource handler because it's buggy (adding grey frames here and there), I hate it.

The only place I noticed the codec working fine is in Windows Media Player. And since MPC has a wide array of customizeable external filters, I was pondering on how to use any of those filters to capture the video using persay a lossless VFW codec and later run it nicely with avisynth and MeGUI.

I already have the lossless codec (Alparysoft), I have the filters (many)... I just don't know how to use them. And I've tried googling for help files but it appears there's no documentation on this matter. If I haven't searched well enough, could somebody be kind enough to throw me a link or two? If I have searched hard enough, could I receive help on this thread?

Many thanks.

MPlayer/MEncoder should be able to play/re-encode True Motion 2.0.
Did you try this ???

mencoder.exe -o "c:\my out file.avi" -ovc x264 -oac mp3lame "c:\my input file.avi"

That almost seemed to work except for the part where the program gave me this message: Couldn't find video filter 'x264', Failed to open the encoder

Plz help, I'm almost there, this can't be so hard... :'(

Mencoder.

Get MEncoder with x264 encoder here:

Or use my MEncoder GUI:

Gotta say that your GUI is awesome and it does work wonders. There was one slight quirk in the installation... what's up with the 120 MB requirement? It's a bug, right?

I just thought I'd bring it up for you to fix it :p

However, I just made another fine discovery that I think I'll add to the thread I started concerning the gray frames. Just now, I've converted all the videos I needed to using directshowsource and I haven't encountered ANY gray frames. It would seem that these disturbing frames appear when an MPEG1/2 source is being worked on through directshow.

Thanks a million anyway, the GUI is still damn awesome. :D Might I suggest the incorporation of Sharktooth's x264 profiles into your GUI? Signed the guestbook too for kicks. Nice work.

That's because NSIS calculates the required space by adding all files that might be installed. So it adds all MPlayer/MEncoder builds that are included in the installer. In fact it will only install the MPlayer/MEncoder build you select, so don't mind.
