Hi :thanks::thanks:
First - Many thanks for all the great work done by the people here. It helps a lot. Now my question:
I start with an DV-AVI file digitizing from VCR (PAL) from Pinnacle USB 510 –
quality – 720*576, 25 fps, Then I open the file in VirtualDub

I use a row of filters
1 neat video
2 null transform(cropping to 690*552)
3 Yadif deinterlacer
4 resize to 720*576, (precise bicubic, A=-0,75)
All Filters are applied in the 25 fps environment.
Then I export with an external encoder (found in a forum)
1 – video, ffmpeg - -f rawvideo -s %(width)x%(height) -r %(fpsnum)/%(fpsden) -i - -vcodec mpeg2video -target ntsc-dvd -me_method epzs -threads 4 -g 45 -b 5800000 -bf 2 -trellis 2 -cmp 2 -subcmp 2 "%(tempvideofile)"
2 – audio, ffmpeg, -i - -acodec mp2 "%(tempaudiofile)"
3 – Multiplexing, ffmpeg, -i "%(tempvideofile)" -i "%(tempaudiofile)" -vcodec copy -acodec copy "%(outputname)"
I end up with a file: 720*480, 29 fps.
Is this the right way to digitize videos in a former PAL, now full HD envirnonment? Can I do better?I am sure. I am really astonished, where the 480 lines and the 29 fps come from.
Many thanks in advance for Your help.

What about replacing "ntsc" with "pal" ?

I would actually recommend you to run neat on the progressive video after yadif.

Alternatively (better approach), don't deinterlace at all and just make the DVD interlaced.
