May I suggest a little reading?

While a bit dated, it’s better than being in the dark. https://en.wikipedia.org/wiki/Comparison_of_video_container_formats

To settle the discussion about m2ts files, Yes, PMS reads them.

To entire argument about what goes in what is relatively moot with regard to PMS. PMS is sensitive to file extensions which are known to carry video. Upon seeing these extensions, PMS will analyze the file (container) and determine what’s in it.

At analysis time,

  1. Determine if the container format (extension) is supported
  2. Determine the audio encoding in the file
  3. Determine the video encoding in the file
  4. Extract the audio and video parameters
  5. Store this information in the database.

At playback time,

  1. Compare the playback requirements (audio and video information) to the capabilities of the player and how it’s being transported (sent)
  2. If the video can be sent unaltered, the transcoder will not be involved else it will be transcoded as needed
  3. if the audio can be sent unaltered, the transcoder will not be involved else it will be transcoded
  4. if the file, as a whole, can be sent as is (in the container / file format on disk), it will be DirectPlayed
  5. if only the container must be changed, Audio and Video show as Direct Stream
  6. if either must be transcoded (changed to a different encoding), that portion will show as “Transcoding”

That having been said, If you have captured any video in:

  1. A container format your player (TV) natively supports
  2. With video encoding and sizes it can natively decode and display
  3. With audio encoding it can natively decode and play

… it will DirectPlay.

As demonstration of what PMS does natively:

Regarding the separate issue of Dolby Vision (aka. bt2100 / 12 bit),

Dolby Vision is content mastering and delivery format similar to HDR10 media profile. It supports both high dynamic range (HDR) and wide color gamut (ITU-R Rec. 2020 and 2100) at all stages from content creation and production to transmission and playback. Dolby Vision includes the Perceptual Quantizier (SMPTE ST-2084) electro-optical transfer function and supports displays with up to 10,000-nit maximum brightness (4,000-nit in practice). It also provides up to 4K resolution and color depth of up to 12-bits (backward compatible with current 8-bit and 10-bit displays).[27] Dolby Vision can encode mastering display colorimetry information using static metadata (SMPTE ST 2086) and dynamic metadata (SMPTE ST 2094-10, Dolby format) for each scene.[28]Examples of Ultra HD (UHD) Dolby Vision is available in TV, monitor, mobile device and theater. Dolby Vision content can be delivered on Ultra HD Blu-ray discs[29][30] over conventional broadcasting, OTT, and online streaming media services.[31] Dolby Vision metadata can be carried via HDMI interface versions 1.4b and above.[32]

PMS currently supports up to BT2020 with HEVC. This yields 4K UHD HDR capability. I have just chatted with one of the engineers regarding BT2100 / Dolby Vision. At this time, it is unknown whether PMS will behave correctly with it in all cases.
