Re: [mythtv-users] De-interlacing on a non-interlaced display
(I'm a MythTV newbie, so maybe I'm just missing something in the config. But, anyway, here is my observation so far.) I have noticed similar issues on my ATSC / QAM MythTV box. When deinterlacing is on, I get weird effects on the OSD. I also see effects on progressive content (720p stations, like Fox-HD, ABC-HD, and ESPN-HD). I had assumed that the de-interlacing would adapt to the video source, and turn off processing when doing progressive content. Apparently this is not the case, but that would be an excellent feature enhancement.

I have noticed similar issues on my ATSC / QAM MythTV box. When deinterlacing is on, I get weird effects on the OSD. I also see effects on progressive content (720p stations, like Fox-HD, ABC-HD, and ESPN-HD). I had assumed that the de-interlacing would adapt to the video source, and turn off processing when doing progressive content. Apparently this is not the case, but that would be an excellent feature enhancement. I have actually been contemplating doing this for some time now. I have just been living with it. I used to disable deinterlacing when watching HD content and re-enable it when watching standard recordings, but now I just leave everything deinterlaced and live with it. HD looks best when it is not deinterlaced because I am using a hd interlaced mode on the tv for that content, but standard def shows show slight tearing if deinterlacing is turned off. - James ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

There are other deinterlacers besides bob... That being said, bob *used* to act like that on my machiens as well. It's not done that in a while, but it might be a post .18.1 thing. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I've been told that turning on opengl-vsync will fix it, but I still get it. It makes the OSD jittery, like it's bouncing up and down 1 pixel incredibly fast. I think (I don't remember because it never worked so I don't use it) that it did it to the broadcast as well, ALTHOUGH it did really smooth the broadcast itself out... especially the examples of the scrolling news ticker and the simpsons (and other animated shows). ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Or try bob, but with a slight speed adjustment (M key then left/right arrows during playback). I see the bouncing at standard speed playback, but at x1.05 or x0.95, the bouncing is gone. This is with myth from a few weeks back, on an NVidia GeForce2 MX, using the binary NVidia driver 1.0.7667. I haven't made time to look for the cause, as I can watch playback at x1.1 or x1.2 for most programmes fairly easily.

If so, speeding up or slowing down will definitely fix any problems you're having with bob deinterlace. :) http://cvs.mythtv.org/trac/ticket/15 Mike (I'm assuming you mean timestretch based on the xN.N values you gave above, even though the "M" key is for menu with the default keybindings and "A" is for timestretch. Perhaps you've remapped your keys... While it's true that you can get to timestretch from the menus, but not with only left/right keys.) ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I remapped as use it a lot to avoid the bounce at x1.0.

Last time I tried, it looked like the frame rate was halved and hence panning was not smooth at all. No such problem with bob.
