iirc.:
  • H.264 support Picture-adaptive frame/field (PAFF) and macroblock-adaptive frame/field (MBAFF) coding. So either per frame (paff) or macroblock (mbaff) it can decide whether to encode interlaced or progressive. (afaik x264 only supports MBAFF)
    read https://forum.doom9.org/showthread.php?t=96598 it should clear what is possible with H.264
    MediaInfo reports:
    • progressive encoding: "Scan type : Progressive" / "Frame Structure: Frame"
    • interlaced, PAFF: "Scan type : Interlaced" / "Frame Structure: Fields"
    • interlaced, MBAFF: "Scan type : MBAFF" / "Frame Structure: MBAFF"
    see: https://forum.doom9.org/showthread.p...00#post1631600
  • H.265 only has the old either the clip as a whole is encoded interlaced or it is encoded progressive.

Quote:
Are there any tools to check if the encoded clip is a properly interlaced one?
Not sure how to anwser this. Can you describe what's the difference between proper and improper interlaced content?

Personally I would look at the frames to decide whether the content is interlaced or not and then decide what I deemed best for my usage goal.
