recognition of interlaced frames

I have a question about the latest doitfast4u version. I have multiple movies lately (PAL) which doitfast4u recognised as deinterlaced. However both dvd2avi and bitrate viewer tell me the source is interlaced. So can I trust doitfast4u and encode is if it was deinterlaced?

DoItFast4U saw it as progressive? Can you send me the logfile and d2v please? I'm not sure my program detects PAL type 100%. If you run it thru dvd2avi does it see it as interlaced from start to finish?

DVD2Avi sees is as interlaced (every vob). How do you want me to send it?

What logfile do you exactly mean?

Hmm.. it seems as if PAL interlaced and PAL progressive use the same .d2v filestructure? Well, from what I understand, you should be able to use that .avs, you'll just have to encode it interlaced. If you have your heart set on deinterlacing it though, uncheck the autodetect option, and check the FieldDeinterlace() option. Then all .avs for that VTS will have FieldDeinterlace() added to them, which will deinterlace your movie.

older versions of doitfast4u did recognise the frametype correctly for pal movies. I can easily change it ofcourse, but it's so easy to have it autodetected.:sly: But anyway the program is great.

I'm 100% sure thta in older version I got an avs with a deinterlace line in it. But now I'm thinking that this maybe was not correct after all (that this line was always there even if it was progressive). To answer your question: dvd2avi says is interlaced (and so does bitrate viewer). A lot of PAL dvds seem to be interlaced (even the main movie). I checked a couple of the dvds I have and a lot are interlaced (probably because they are copied from a NTSC source or so). For the main movie I don't think you'll notice a quality loss if encoded without deinterlacing. But for the extras it's terrible ofcourse. I must say that I always use the vob file and not the m2v to analyse (but I don't think that makes a difference?). Bitrate viewer seems to analyse it correctly. It also sees if it's progressive, because if I understand you correctly it looks like PAL is always interlaced if you solely look at the headers? For me it's not a really big problem, I'll just check first and then manually turn on deinterlace. I can only imagine that other people who are not aware of this will be disappointed by the queality of encoding of especially the extras. But anyway thanks for all the effort!
