Is HEVC better than 4K channels?
Last edited:
HEVC can be used for all different resolutions including 4k, it just has better compression than other older formats such as h264, which means uses less data and should work better with slower internet connections.

I think 4k is better
Some providers say HEVC/H.265 but the channels aren't actually HEVC/H.265 just in a group that says so you need to check yourself to verify. The main importance of this video standard as it relates to Iptv is that it is essential for 4K HDR channels since AVC/H.264 doesn't support the Bt 2020 color gamut that you need for HDR.
HEVC/H.265 can also provide the same quality as AVC/H.264 while having a lower bitrate since it compresses the stream more but the drawback is that you need modern devices to hardware decode since it is more power consuming than AVC/H.264.
Besides this there is AV1 (Netflix and YouTube), VP9 (YouTube) and H.266 (8K) that are used and they basically do the same HEVC/H.265 with AV1 and H.266 as the next replacements.

Like I said they improve nothing for end user. That is a nonsense 50fps is better for ball judder which all 4k are.
They will make processors and ram work harder. Like I said they primary purpose is to reduce bandwidth on servers

AV1 is less efficient but royalty free compared to H265.
VP9 is royalty free but less efficient than AV1.
Also AV1 has better support for HDR and WCG compared to VP9.
I think AV1 is the better choice but at a cost of higher CPU usage.

I have never seen ball judder when watching 50fps but I do use AFR.
But if I watch 25fps and don’t use AFR then the image is impacted and doesn’t look good.
I think AFR is key when watching content at lower frame rates.
The TV needs to know the frame rate that is being fed to it from the device.
It's the 50fps that's the key. AFR is just adjusting your settings on tv. Your device will read the frame rate regardless

AFR is adjusting the frame rate on the device and feeding it to your tv.
If you watch 25fps second content on a device and the device it is set to 2160p at 60hz the tv doesn’t know it’s receiving 25fps content.
This will cause judder.
The best way to fix it this is use a device that has AFR or an app that has AFR.
If are use android TV 11 OS or lower than you would need to use an app that has AFR because AFR was only implemented on android TV 12 OS.
You should always try to match the frame rate for a smoother image

Not sure what you mean but if you have AFR off the device attached to your TV will not match the frame rate and will not switch accordingly. Whether you are using the device AFR or the app AFR on the device.
The TV needs the information from the device so the TV can match it.
I prefer to use AFR if the app has it instead of the AFR on my device. IE Syncler,Kodi Tivimate etc.
I especially like the AFR on Tivimate because it doubles the frequency on the refresh rate.
I have a native 120hz tv so Tivimate causes 50hz and 60hz feeds to refresh the image at 100fps and 120fps making them even smoother.
Yes that's what I am saying the device knows the frame rate and plays that frame rate regardless
When you turn on AFR it changes the tv settings so you get the benefit

It’s when you said “My auto frame is off. Device knows the frame rate”.
That confused me.
So you which do you use device AFR or Tivimate AFR?
