    I have an iPad Pro 10.5, decried to download a purchased iTunes film for offline video. It was set to playback quality - best available HDR was on, the film size was 8.35Gb. This is a little too big for a 64gb as want to download a few.

    So as I only will be watching on the actual iPad itself, should I change to; Playback quality - Good, and switch off HDR or leave HDR on etc?

    Also if its in "Good" quality is this the 720P version? as looking on the iTunes Store the difference between 1080P and 720P size are sometimes only about 500Mb, will it matter on an iPad screen though?

    thanks

    iPad Pro 10.5: 2224-by-1668
    1080p: 1920-by-1080
    720p: 1280-by-720

    I'd say stick to at least 1080p downloads. I think someone's regretting their 64GB capacity ;)

    Honestly I would have expected a 3-4GB option. Estimates on apples store would be handy

    those don't have HDR estimates on though so adding HDR must make it even bigger? Is it worth it for watching on iPad screen?

    Not for the price I got it. Yes I'd have preferred 256Gb but basically sold an iPad Air 2 for same price.

    Come to think of it now, I've been downloading direct from iTunes store to iPad, I'm sure there's an option via iTunes on Mac to download the 720P option...

    Well, the 10.5 has an HDR capable screen. Look at a few demo videos to see if you like the difference

    Try suppose could download a version with and disable it and download it again, not sure it will allow 2 versions of same movie and one with, one without at same time.

    Thanks

    Turn off HDR download, and your HD movie size will go down to a reasonable 3-5GB.

    No noticeable difference in iPad Pro 10.5 though?

    You mean in image quality? HDR download vs standard?

    Color range is better in HDR. Worth the extra storage used on a portable device? Only you can decide.

    Buying Blu-ray, I opt to pay the extra $5-10 to get the 4K Ultra HD version. It enhances the experience but for me, these features are unnecessary to simply enjoy a movie. Hence on mobile, I tend to prioritize size over quality (to a certain extent).

    My device (iPhone 7+) doesn't qualify for UHD/HDR playback, so those formats are not offered. And yes, they would be larger of course.

    Can you even get HDR (high dynamic range) with HD (high definition, i.e. 1080/720p) content? I've never seen HDR offered with anything lower than UHD (4K) resolution.

    The higher resolution (4x as many pixels), higher efficiency codec (50% less data for the same amount of pixels) and higher colour depth (10/12bits instead of 8?) should let you extrapolate the 4K/HDR download size. I doubt the HDR metadata would add much to the equation, although Dolby Digital per-scene metadata would no doubt weigh in heavier than HDR10 per-movie metadata.

    If someone with an iPhone 8 or X, or an iPad Pro wants to look up the sizes, the movie info I screenshot above is for Pitch Perfect 3.

    Sure. 4K and HDR are two separate things. Plenty of anime fansubs were encoded at Hi10P even before 4K Blu-ray became available. For iTunes downloads on iPad, you can't get 4K anyway.

    Alas, I don't believe the regular Blu-ray spec supports HDR, hence, it's only available with 4K on disc (anyone feel free to correct me on this point).

    Well, no anime fansubs on the iTunes Store ;)

    But yes, the iPad Pro and iPhone X lack 4K capable displays, however, they do get HDR.

    So, the question is, was the OP's 8.35GB download to iPad Pro actually a 4K/HDR movie that was then downscaled for playback by the device to fit its display, or does the iTunes Store provide lower resolution HDR downloads for iPad Pros (and iPhones 8 and X), meaning the 4K/HDR download would be even bigger than 8.35GB? I'm guessing the former.

    Lower resolution HDR, afaik (that's actually what I meant in my previous post). I remember reading somewhere that iTunes enabled 1080p HDR downloads for iPad but does not allow 4K download.

    So switched off HDR and it's around 5Gb size now.

    The better test would be to have both of the same movie bought from iTunes, one with HDR on, one without to compare but can't as the movie is already downloaded whichever you pick.

    Even 5Gb is a large file tbh for watching offline as a few movies have taken up 25Gb already.

    Well you could have two of the 10.5” iPad Pros. :)

    If you have 4-stream plan on Netflix, some of its content is HDR-enabled.

    I do have Netflix but just the 2 people version.

    Good idea, I'll just pop to Apple! Ha ha

    It is funny how we see 8GB HDR for movies as "too big", while it wasn't too long ago that one DVD movie (standard def) was 8.5GB in size (dual layer).

    Personally, I would just download movies at regular 1080p on my iPad. Heck, I would be fine with 720p as well, since the situations where I would be enjoying the movie on the iPad would be in situations where I wouldn't be able to fully appreciate the full quality anyway (eg. watching on a plane).

    That's actually the best way to compare. Either two Pro 10.5 or Pro 12.9 2nd gen. :D

    Blu-ray is 25-40GB. Besides, back in the DVD days there was DivX/XviD at 500MB-1.5GB per movie depending on length and complexity.

    If there was a massive different in size, sure. Alas, iTunes 720p downloads are usually just a little bit smaller in terms of file size than 1080p.

    That was sort of original question. I'll be watching on iPad screen for when I'm on a plane and away. So was wondering if it made any major difference for these circumstances.

    Seems to be about 3.5Gb difference so maybe not worth it. The 1080P and 720P version (is this what best and good quality refers to in settings?) is 5Gb and 4.52Gb so not much difference, but this is one specific film not sure if others are like this, and not sure on difference on viewing on the iPad to see if much difference.

    *Looked at a few now on iTunes store and difference between 1080 and 720 seem to be around 500Mb*

    I think that's pretty common. I noticed similar with my Game of Thrones downloads. The 720p usually doesn't save you a lot of space.

    As for Good vs Best, I think Good might actually be referring to SD. Only way to confirm is to switch settings then download.

    That’s because the audio remains the same in size. Once you go to highly optimized video compression, the large chunk of data becomes the audio, especially if you have multi channel audio. Now I don’t know if Apple downmix the audio to simple stereo or not on lower resolutions.

    Pretty sure iTunes videos downloaded to iOS devices are stereo only.
