Hi, I am unable to get interlaced video to playback smoothly. Sometimes frames are dropped/skipped and sometimes no frames are dropped/skipped but the video is not smooth. Also deinterlacing can be intermittent resulting in combing and sometimes the video is poor quality. The files play smooth when using MPC-HC. Any help appreciated, thanks.
To reproduce, download the following sample files and adjust the Kodi settings for Render Method = DVXA, DXVA2 = ON, Deinterlace = Auto. The easiest thing to look for is stationary text flickering and wobbling, then the fluid motion of screen movement.
Text_wobble_&_smooth_motion_576i50_(burosch1).mpeg (30mb) [LINK] or [LINK]
Text_wobble_1080i50_(BBC1HD).ts (60mb) [LINK]
Text_wobble_&_smooth_motion_1080i50_(BBCnewsroom).ts (50mb) [LINK]
Smooth_motion_&_High_bitrate_1080i50_(EuroTV).mp4 (300mb) [LINK] or [LINK]
My Test Results.
Note.
1) Though the problems are obvious even when using a 60hz screen, the sample video files are 25fps interlaced and 'perfect' smoothness can only be achieved when the graphics card output is set to 50hz.
2) Don't forget it is possible to install Kodi to a 'test folder' and run Kodi in portable mode by creating a shortcut with the '-p' switch eg. ' C:\Kodi17\Kodi.exe -p '. This will keep all Kodi userdata and settings separate.
