I have a 4:3, NTSC, Interlaced video. I used TMPGEnc to handle the NTSC, so now I have 23.970fps, instead of 29.9. I convert the tpr file to a avi (vfapi), then load it up into GK. At the compression test screen, I select 'field deinterlace', and I get a avisynth error that says "FieldDeinterlace: YV12 format only" "LastCompCheck.avs, line 30". This disc is american. This is the first season of seinfeld, season 3 works fine. I am at a loss. I could really really use some help.
i think you can IVTC in gordian knot. not sure how you do it through gknot. but i'll either use telecide using decomb plugin. or TIVTC using TIVTC plugin so no need going through tmpg and vfapi. that will heacka slow and you might lose quality.
What actually happened early in the process (29.9->23.970) was IVTC which is a bad idea if the source is truly interlaced (television shows are generally interlaced). What you should do here is rip with DVD decrypter -> open vobs with DGindex and save to dv2 -> open d2v in GK and there select FieldDeinterlace If you want to go on with your current method then adding ConvertToYV12(interlaced=true) before your FieldDeinterlace-command will help here.
