Do TV's not deinterlace media?

Not sure what category to put this in. Say you rip a series from your DVDs using MakeMkv…that series happens to be interlaced. You then put that series on Plex and as you watch it, it looks totally like it is not being deinterlaced at all. I thought TV’s deinterlaced for ages now? My tv is a Vizio 4k about a year old. We have a 2 year old Samsung 1080p…same. Am I going to have to encode these using handbrake decomb to get them deinterlaced?

Some of the Plex Players have manual de-interlace settings but I’ve never used them or had cause to.

HandBrake has deinterlace and comb filter settings to address this situation which you may need to experiment with. Maybe not what you want to hear but you should be able to batch these up for HandBrake to process. Problem solved once and for all.

Well, yes of course they do, but do they do it better than an app or a stand alone program? All LCD/OLED panels must de-interlace as they have no way to display interlaced content like the good old CRT.

You’ve raised a valid point and consequently the reason for the OP’s post. If interlaced media isn’t properly de-interlaced at RIP time, you have to rely on the player (or TV) to be able to fix that.

Anyone ever seen 2160i with UHD? There’s a reason for that.

The player software inside of “Smart TVs” is only geared towards internet streaming services. None of these streaming services are providing interlaced content.
(Note, that I am not talking about the built-in tuner here.)

So this use case is simply not needed, nor is it tested by the device manufacturer.
That there is a small enthusiast software solution, which allows streaming pretty much any file format to the TV is simply not on the radar of the TV manufacturers.

And even if they know about Plex, they won’t test or optimize their firmware for it, because it won’t generate much additional sales.

Hence why you will often find the following advice in these forums:

Don’t choose a TV device by comparing its ‘smart’ features. It is only useful for the first ~4 years of its life. Afterwards, these features will fall into disrepair because the TV manufacturer won’t patch the firmware anymore.
If you want a solid player device for Plex, pick a plug-in/STB solution. These devices are usually getting firmware updates for longer times than your average TV.
Particularly the high-end devices like the Android Shield Pro.

And if the external device will eventually get outdated by technological advances (e.g. new codecs) then you can acquire a new one for a much lower price than what buying a new TV would cost.

The apps do deinterlace fine in my experience. However, I wonder if you’re using the transcoder, because if you are, well, the transcoder is hardcoded to deinterlace to half-rate in any and all cases, throwing out half of the constructed frames. So if you have 60 fields, you’ll end up with 30 frames, not 60, and this will look choppy for a lot of things (especially sports).

when you say using the transcoder…I’m assuming you mean Plex transcoding instead of direct playing? The answer is no. Everything I have direct plays…well I guess I should say “direct streams”. I’m just going to encode the video since I guess the player or TV can’t deinterlace.
