When I watch standard, interlaced DV-AVI clips with mplayerc, the picture is deinterlaced and flows smoothly with original framerate. If I watch them with VLC player for example, they look as ugly (interlaced) as they should...

The question is, how do I achieve deinterlacing, while keeping the framerate (as in the ouput of mplayerc)?

So far I've been using TDeint, which produces pretty good results quality-wise, but cuts the framerate in half.

Duh, should have spend more time learning TDeints parameters.

To keep the framerate (25i -> 25p), use one of these: TDeint, Yadif (default mode), KernelDeinterlacer, TomsMoComp, 5-Tap Lowpass...
To double the framerate (25i -> 50p), use one of these: Yadif (bobbing mode), KernelBob, DGBob, ...

With MPC+FFdshow You can also use Dscaler's deinterlacers. 95% of them double the frame rate. Dscaler probably has the best variety of top-quality deinterlacers around.

To use Dscaler's deinterlacers (and filters) in ffdshow:

- Install DScaler from here http://sourceforge.net/project/showfiles.php?group_id=7420 . I use version 4.1.17
- From FFdshow's video decoder dialog:
- At the "Tray, Dialog and Paths" panel: choose DScaler install directory and set it properly
- At the "Deinterlace" panel: you will now see many more deinterlacers from DScaler

I recommend Video (MoComp2) and Video (Greedy, Hi motion) for properly interlaced video content.

If you use VLC, the only deinterlacer iirc that doubles the framerate is BOB. Video -> Deinterlace -> Bob

In addition to LoRd_MuldeR's functions, you can also try :
- FieldDeinterlace() (part of the DeComb package), I'm using this function, if it fails, I'm using Yadif()
- MPC built-in deinterlacer is: blur(0,1)
so if everything is failing, you can stick with it, but it blurs out much detail, compared to the others ...

The Linear deinterlacer also doubles framerate, but with linear interpolation, so that the image isn't quite so jigsawed.
