I want to encode DVD to MP4 for my daughter.
The sourse is PAL 25fps INTERLACED ( from DGINDEX )
The analyze result from avscreator is PARTIALLY INTERLACED.

I tried YADIF BOB to do deinterlace, the video result is very good but I meet sync problem after I muxed the audio. Maybe it is because the source is partially interlaced but I still used BOB. Although YADIF ( no bob ) works ok, I like BOB which looks same as the HW deinterlacing.

I also thought about leaving the encoded video interlaced in final MP4, and let the MP4 player to do HW deinterlacing. ( as it do to the DVDs ). But after I encoded it ( no deinterlacing in AVS script ), I got a file which is PROGRESSIVE showed in MEDIAINFO tool. And the MP4 player didn't do any HW deinterlacing to this file and the video looks very interlaced and bad, same result in my PC.

please anyone help.

Did you use your eyes to see if it is interlaced? I guess you did when you watched the output...

x264 will only automatically use interlaced encoding when avisynth gives it field-separated input, which it weaves back together. Otherwise you need to tell x264 to do so with --tff or --bff.
