I have a DMR-EZ49V VCR (HDMI Out) and a HDMI Capture device. This workflow only allows me to capture the source at 576p (Lossless).
I understand that the Panasonic is simply bobbing to 576p so I should be able to undo the deinterlace losslessly?
I've tried using SeparateFields().SelectEvery(4, 0, 3).Weave() but I'm noticing two things:
1) It appears to work in that I can see frame-by-frame that the combing is there, but then at certain points later in the test capture, the combing disappears, even on frames with motion.
2) To confirm this inconstant behaviour I recapped the same scene, ran it through the same script, and unlike on the first capture where I get the combing, on the second I don't!
Attachment 1. Here's the 1st capture, showing two consecutive frames, at a point that shows a successful merging of fields.
Attachment 2. Here's another area of the 1st capture where no interlacing shows (even over multiple frames of movement)
Attachment 3. Here's the same frame from the 1st and 2nd capture after merging fields. One successfully interlaced, the other shows no interlacing over any of the frames:
...I've tried (4,1,2) as well.
