Windows Media Player 12 automatically IVTC'ing content

[chaynik]

I just noticed that on a fresh install of Windows 7, the default shipping Windows Media Player 7 (with no 3rd party filters) will IVTC hard telecined MPEG-2 content and do a hell of a job at it! In fact during my testing consisting of playing back a ton of pre-HD music videos shot on film (the worst for IVTC because of cadence changes at all the quick cuts), it performed better than Avisynth & TIVTC/Decomb (more correct pattern matches and no interlaced flash frames). I'm curious if anyone else has noticed this and whether they have any insight on the IVTC algorithms WMP12 employs.

Also worth a mention is that the DVD Player app shipped with Mac OS X also performs IVTC on hard telecined material and does a quite remarkable job as well.

WMP12 lets the graphics hardware to the IVTC and Deinterlacing.

I had some really good results with that, as well.

Wow, I have never heard of GPUs doing IVTC (deinterlacing, yes, but not ivtc). This is very impressive, is it documented somewhere?

[nevcairiel]

Probably is somewhere.

If you have NVIDIA, there is an option in its control panel to turn it on/off. Thats how you know its doing it, at least. :)
Dunno about ATI.

For AMD cards its in the CCC under Video. Look for the generically labeled 'Basic Video Quality' panel.
