[HELP] Telecine Settings->Analyse
#4
Sure, look at the content.
If you overwrite the scanorder to 'progressive' and the Vapoursynth Preview shows no combing the content is progressive.
If you leave the scan order (tff or bff) and bob deinterlace the content (in example using QTGMC + Bob) and look a the frames:
If each frame is different then the content is interlaced.
If you see a 3 different and 2 identical frames the content is telecined.
If you see another pattern of different and identical frames the content is mixed.

found some old list I once wrote:
Quote:Typical interlace patterns:
  1. content is progressive:
    • applying AssumeTFF().Bob()* you will see: stop -> forward_movment -> stop -> forward_movement **
    • applying AssumeBFF().Bob()* you will see: stop -> forward_movment -> stop -> forward_movement **

  2. content is field shifted:
    • applying AssumeTFF().Bob()* you will see: backwards_movment -> forward_movment -> backwards_movment -> forward_movment **, ***
    • applying AssumeBFF().Bob()* you will see: forward_movment -> stop -> forward_movement -> stop **, ***

  3. content is interlaced TFF:
    • applying AssumeTFF().Bob()* you will see: forward_movment -> forward_movment -> forward_movment -> forward_movement **
    • applying AssumeBFF().Bob()* you will see: forward_movment -> backwards_movment -> forward_movement -> backwards_movment **

  4. content is interlaced BFF:
    • applying AssumeTFF().Bob()* you will see: forward_movment -> backwards_movment -> forward_movement -> backwards_movment **
    • applying AssumeVFF().Bob()* you will see: forward_movment -> forward_movment -> forward_movment -> forward_movement **

  5. content is interlaced XFF with blending:
    • same as the corresponding interlaced pattern, but you will also see some blended (= ghosted) frames in-between

  6. content is telecine:
    • applying AssumeVFF().Bob()* you will see 3 times forward_movement 2 still frames
  7. content is mixed:
    • applying AssumeVFF().Bob()* you will see a mix of any of the above
* in Hybrid you would use QTGMC+Bob
** then moving through the content
*** or vice versa
which might help.
