Hello!
I can't get deinterlacing to work no matter how much I google. I've checked older threads and I've tried the following:
1) Set project settings to progressive
2) Set scanning to force progressive on render menu
3) Added "deinterlace=1" to output profile
4) Added "progressive=1" to output profile.

None of these work by themselves or when all of them are on. My source material is either DVD PAL standard MPEG-2 or DV PAL standard avi. No matter what I try my output mp4 is interlaced. In my current process I have to cut the footage and save a duplicate as uncompressed avi and then encode it with handbrake, which deinterlaces just fine.

this happens also on 17.08.1 ?

Deinterlacing (force progressive option) does not work anymore with kdenlive 16.12.3 (Kubuntu 17.04).
I tried also to create a new VOB rendering profile including "progressive=1" but it does not work, as I can easily see with VLC.

My turnaround to create my DVD is using ffmpeg with -deinterlace option:

Code: Select all

ffmpeg -i movie.dv -pass 1 -target dvd -an -y /dev/null
ffmpeg -i movie.dv -pass 2 -target dvd -acodec mp2 -ab 224000 -deinterlace movie.vob


I think ffmpeg uses yadif deinterlacing filter when you use -deinterlace (it is therefore equivalent to -filter:v yadif). See https://ffmpeg.org/ffmpeg-filters.html for other deinterlacing filters.

After upgrading to Kubuntu 17.10 beta with Kdenlive 17.08.1, the problem is still present.

Example of a VOB file rendered using the "progressive" option in Kdenlive 17.08.1 :

Code: Select all

$ ffmpeg -i essai.vob
Input #0, mpeg, from 'essai.vob':
  Duration: 00:02:26.05, start: 0.034667, bitrate: 5304 kb/s
    Stream #0:0[0x1bf]: Data: dvd_nav_packet
    Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt470bg/unknown/smpte170m, bottom first), 720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 90k tbn, 50 tbc
    Stream #0:2[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 192 kb/s

My workaround at the moment is cutting with virtualdub and exporting with ffmpeg as an external encoder. It's a bit slow since virtualdub encodes uncompressed temp files first before pushing the files to ffmpeg for encoding and muxing. But it works for now unless I need to do something more complex than just cleaning up both ends of the video.
