Filters: resolution: 1080p vs 1080i

It would appear, unless it’s my user error, that Plex can not filter accurately for 1080i vs 1080p in terms of setting the resolution as a filter. I have movies in both formats. One will notice that the GUI (Windows desktop player) only allows for “1080p” or “480p” or “SD” as specific choices. If one chooses 1080p, one sees “1080” only as the filter variable. Then in that case, it does accurately cull all of my 1080i or 1080p movies given the “1080” that it unwantedly defaults to. However, if I specifically type “1080i” in, all 1080i and 1080p movies are included in the filter list as well as SD movies (strange behavior right?). When I specifically force “1080p” by typing, only 1080i and 1080p movies are filtered; no SD. Is all this a bug? My 1080i and 1080p and SD movies are correctly identified as such by Plex, btw, in the individual movie view.

It depends who you talk to, I guess - or where they live.

Here, in this part of WV - 1080i only lives as long as it’s in the air from the broadcast tower to your TV or recording device. Once it lands it’s called 1080p. It’s resolution is 1920x1080 and it has interlaced fields.

Other folks, in other areas - and in some technical reference manuals - call 1080p with interlaced fields 1080i. It’s resolution is still 1920x1080.

Confused yet? Don’t be.

Plex (and everything else you own) calls them both 1080p so the moral of this story is you can’t filter for interlaced 1080p content in Plex.

If you’re filtering for 1080i and it’s giving your SD content - that’s a bug. 1080i is NOT SD by any stretch of anyone’s imagination.

Are you trying to find 1080i files to eradicate them?
If so, you can use ExportTools to generate a list with much greater technical detail than the filter system in Plex will ever allow you.

Don’t ‘Eradicate’ - Decomb.

Handy Handbrake Guide in my signature…

Once that filter is applied anyone’s definition of 1080i will happily be 1080p.

:slight_smile:

Nah, you guys don’t understand my point…

  1. There is no interlaced progressive video; i.e., no interlaced 1080p. “Other folks, in other areas - and in some technical reference manuals - call 1080p with interlaced fields 1080i… the moral of this story is you can’t filter for interlaced 1080p content in Plex.” I’m definitely not confused. I understand the formats. (Btw, no networks broadcast at 1920 horizontal resolution. They broadcast at 1440x1080i59.94, a subsampling. ABC and ESPN, I believe, still broadcast at 1280x720p29.97. In the early days of HD, I would receive MPEG2 streams at 1920x1080i59.94 from certain DishTV channels like Voom HD or Monsters HD. Occasionally some of these broadcast at 20Mbps too. As the years went by, I saw less and less 1920 and more and more 1440. And more instances of MPEG2 broadcasts in the 5-10Mbps range, to save bandwidth I guess. I will tell you a 1440x1080i ~8Mbps MPEG2 broadcast looks noticeable worse than a 1920x1080i 20Mbps broadcast. And I believe all Dish and DirectTV live channels now use the 1440x1080i59.94 format except for those few channels like ESPN e.g. that use the 720p29.97 standard. Especially true once MPEG2 encoding was left behind in favor of H264 encoding).

  2. I say again: Plex correctly identifies the video format (progressive versus interlaced) in the individual movie view of every file I own. I.e. “it knows” what’s 1080i and what’s 1080p for my files that are 1080i and 1080p respectively (just as it knows if a file is is a VC1 codec, or an H264, or MPEG2, etc.). So it knows the format (and the codec). Thus, in my opinion, it would be a simple thing to correctly filter 1080i vs 1080p. Much like it would be simple to filter for MPEG2 or H264 etc.

  3. For filtering purposes, Plex somehow inexplicably thinks that SD (480i or 480p) files are “1080i”.

  4. Plex does not think that 480i or 480p files are “1080p” however.

  5. For any of my 720p files, Plex is not confused.

  6. I am not looking to eradicate these files or decomb or transcode or Handbrake them etc. I have many native 1080i MPEG2 .ts broadcast files (movies) that play beautifully from within Plex. Just would like to know if Plex will “fix” filtering to accurately filter for those versus my native 1080p files. It’s not a big issue. I’m fine if Plex chooses not to “fix” this. This is just an FYI to the Plex team.

If Plex actually labels 1920x1080 interlaced as 1080i - that’s news to me.

That would mean it’s the ONLY thing in this house that does - 'cause everything else just calls it 1080p.


an example

Thus, it would seem “easy” for Plex to filter for 1080i vs 1080p. However, it does not.

Please stop spreading this partial truth that is doing a disservice to others. In some cases cable and satellite companies are reducing 1920 to 1440. THIS DOES NOT OCCUR WITH OTA SIGNALS OR ALL MSOs PROVIDING SERVICE.

I will bring up the topic of 1080i as a filter variable with the developers.
