Forcing progressive mode

[amurphy7701]

Hello

I have a (small?) feature request.
I recently ripped a PAL movie.
The fact is that the analysis of the video by autogk concluded it is an interlaced source.
I never saw a film (cinema) that would have been converted on PAL DVD as an interlaced video, so logically it IS a progressive source, that is detected by error as interlaced.
Would it be possible to have in the advanced option, a "force progressive mode" option, the same way we can force hybrid?

TIA

AutoGK is never wrong :) If it says that there is interlacing then it is there, so :logfile: Only after that we can see if its just into/credits or full movie is interlaced.

Maybe you just haven't seen enough PAL DVDs. It could have shifted fields (in which case you'd do better to use GKnot to fix it), or maybe they used an NTSC master for the PAL DVD. Although rare, interlaced PAL DVDs of films do exist. Did you take the time to examine the DVD before or after converting to AVI?

I posted the log file as asked

I took the time to upgrade to the latest version of AutoGK.

There is little chance this film was converted from NTSC, as it is a French film, typically the kind of film that is hardly exported elsewhere :)
In fact, if it were possible, this DVD would have been in SECAM strandard :D

I modified the AVS script to remove the deinterlacing filter and the resize, and edited it with VDubMod, to analyse intro&end credits. There doesn't seem to be any interlaced picture, as far as I can detect them.
BTW, the intro credits is made of stripes that move horizontally. Is there a chance that if the original image is of bad quality (eg color bleeding on the edges), the interlaced detection would be positive?

Log says that there is almost 5% interlacing. While its entirely possible that there are some scenes that just look like interlaced, but in fact not - I would consider "force progressive" useful only if:

- there are many sources like that
- you actually able to see the difference with or without deinterlacer in the output file

Low amounts of interlacing still should be deinterlaced and KernelDeInt is very good at not-destroying progressive material, but feel free to check that yourself.
