A bit about codecs and file sizes

Picture Resolutions
4k 2160p
FHD 1080p
HD 720p

Dolby Atmos is not a codec it's a audio format. E.G. would need a Dolby Codec
Dolby Digital+ is a audio codec
Flacc is a audio codec
AAC is a audio codec
MP3 is a codec
MP4 is a codec

File and compression types

MKV open source file type.
AVI is not open source

Hevec 264 compressed files using less bandwidth
Hevec 265 compressed by upto 50% more than Hevec 264

So e.g if you were watching a action movie the closest to cinema quality would be

4k 2160p dolby atmos gives the impression of sound above and below head etc.

If I was watching a musical or concert
4k 2160 FLACC would be best lossless audio basicly

You can also get FHD in the various codecs aswell

So the size of the file is basicly irrelevant aslong as the resolution and sound is what you require

But it means nothing if all your devices are not compatible. And you have the correct equipment in the first place

A audio format is the structure for storing the digital audio

A codec is tool that encodes and decodes the data

Files that have been compressed will make a devices processor work harder but use less bandwidth

Its also a good idea to set your app to auto resolution and frame rate if possible

All a bit geeky i know but some of you may be interested of course there are more file types and codecs but main stuff is covered

You say the file size is irrelevant but the smaller the file size the more it’s been compressed reducing data leading to a poorer quality file.
The closest to cinema quality is a Blu-ray remux which would have lossless audio.

Yes the file has been compressed but it dose decompress using a video decoder

To the naked eye you wouldn't notice a difference the exception maybe would be if you watched on a massive screen

Remember quite a bit is also taken out of some of these files like different audio files for language's and subtitles etc

I find remuxs are better quality for watching movies compared to compressed files especially the audio and the image doesn’t always look as vibrant and as sharp.
I don’t see the point in watching a compressed movie file when you can watch a Blu-ray remux file.
Unless you have a low internet speed connection or your hardware doesn’t support the codecs.

I second that, there's a massive difference in picture quality between say watching a 4gb movie on netflix or the 70gb blu ray of the same movie

Well yes there is that argument I personally try and strike a good balance i do like atmos because it's a more imersive sound but unless you have a fairly good home theatre setup pretty pointless
