In Premiere Pro CS3, I created a DV PAL project, Upper Field First, or TFF. Project is TFF because the source is MPEG2 TFF, and I encoded the MPEG2 to DV with ffmpeg with -top 1 parameter. With the -top 1 parameter, ffmpeg creates TFF DV.
In this premiere project I have 2 sequences.
When I render sequence 2 to avi lagarith TFF (lossless intermediate), deinterlace it and encode it to h264, there is back and forth motion, as if that lossless intermediate is BFF. AssumeTFF was present in the avs script, before QTGMC.
When I render sequence 1 to avi lagarith TFF (lossless intermediate), deinterlace it and encode it to h264, motion is fluid, as if that lossless intermediate is TFF. AssumeTFF was present in the avs script, before QTGMC.
The DV clips added to sequence 2 are not the problem, they are are TFF, and there is no back and forth motion if I deinterlace and encode them to h264 progressive, using AssumeTFF and then QTGMC in the avs script.
This means that the problem originates from Premiere. It looks like Premiere renders TFF from one sequence inside a TFF project, and BFF from another sequence inside the same TFF project. But all dv clips from sequence 1 and sequence 2 are TFF.
