    Which of the two settings give you the best quality.

    4K video recording can -only- be in high efficiency. (Including 1080 at 240FPS)

    I mean the regular setting vs the new one.

    That’s not true. 4K@60 can only be high effficiency, however 4K@24 and 4K@30 does not have to be with high efficiency.

    High efficiency is the same quality, just better compression.

    Yeah I meant at 4K 60 FPS, sorry that wasn’t specific like I was with 1080 @240.

    Just keep in mind that if your doing 4K @ 60fps and you take a 30 second video how much space you’re going to be using

    About 200MB.

    I wanted to use 60fps but I don’t know what happens with the quality and the bitrate.

    Also with 30fps as well. But I don’t know what’s the difference in both formats for quality. I don’t want one to have worse quality than the other just for saving storage space.

    Quality is the same. It’s just a different type of compression.
    If you’re wanting to use a high bit rate with your 4K recordings you’re going to have to use a 3rd party app. FiLmIcpro is probably the best and it even lets you record in flat gamma and log gamma. Everything, and I mean everything, is totally adjustable from frame rate, bit rate, shutter speed, iso, WB, focus, zoom push and pull (setting the push and pull points and the zoom speed), same for focus push and pull, recording aspect ratio, etc.

    4k @ 30 FPS is possible with the standard CODEC. Only 4k @60 FPS requires HEVC

    @OP It really comes down to compatibility and how you plan to share or incorporate the video into your workflow. As started above you have no choice with 4k @60 FPS but at 4k 30 FPS. H.264 4K @ 30 FPS is captured at a bitrate of ~46Mbps where H.265 4K @ 30 FPS ~24Mbps. They both look roughly the same and neither uses 10-BIT nor stereo audio recording (WHY APPLE!?) The HVEC takes up less space and integrates well if you use include and do your editing in iMove / Final Cut Pro X... otherwise you might want to use the standard H.264 CODEC.

    If you want to record in higher bit rates I would recommend FiLMiC Pro. With 4K resolution you can record as high as 100Mbps and you can record in flat gamma and log gamma (wider DR), of course you have to color grade then in post.

    What’s the difference between high efficiency and standard 4K @60 FPS?

    On the iPhone you can not record 4K @60fps unless you use the high efficiency storage format
