Hi,

I have a video that was originally PAL, but converted to 1080mbaff30 for its home video release. It has the usual PAL pattern of 4 clean frames and 2 blended frames. Normally I can clean this type of material up 100% with a bob+srestore, however only on pure interlaced content (which is what I usually deal with). When trying yadif(mode=1,order=1) (it is TFF, I verified) alongside srestore it's still leaving in blends, something I don't get when restoring 100% interlaced video. Seeing how the only thing that's different is that the source is mbaff rather than interlaced, I'm going to guess that's what tripping Yadif up but I could be wrong. After all, you would expect there to be no bleds once the video is bobbed, yet there sitll is. I've also tried a few other things such as fixblendivtc but no dice in removing all of the blends. Anyone else have anything that comes to mind that may work? Thanks.

You should probably inverse-telecine (IVTC) your source. It reads like there are blended fields from a poor conversion. If so, it might be difficult/impossible to fix properly.
Upload a sample then someone might be able to help.

Not telecined, but progressive video encoded as interlaced, with blended fields from an incorrect PAL to NTSC conversion, I think.
Can't fix it properly. Perhaps someone else .....
