Looks like the MacBook pros w/ Intel 4000 IGPU and Intel HD 4000 IGPU in general all support 2160P/30 , MacBook Pro with Intel 5000 IGPU and Intel 5000 IGPU in general support 2160P /60 for playback . One would likely require a high performance GPU with dedicated GDDR5 memory for editing ,Mad VR rendering and things like that @4K .

The youtube content has pixelation and noise. Im guessing this is youtube compressing it. Is there any actual REAL 4k (4096 x 2160) video that is uncompressed?

Does anybody know what, if any, Apple's plans are with 2160p trailers? Apple's trailer page is my main source of 1080p trailers and at present 1080p is all they offer. Will they continue to use H.264 or will the start using H.265(HEVC)? Does anybody have a date when we can look forward to seeing 2160p trailers from Apple?

Thanks for sharing...
I see 4 options for video type in 4k Downloader (MP4, FLV, MKV, 3GP)
I am asking because Not all videos appear to be working as Mp4 on my Samsung 8550.


LMK - Thx in advance.

your not looking hard enough

4k UHD USB stick 3840 x 2160 mp4 h264 21 Gb 65mbit USB stick
4k Prores UHD 3840 x 2160 mov Prores 120 Gb 370mbit Hard drive

Uncompressed UHD would be 3840pixels*2160pixels*12bits/pixel*24frames/sec ~= 2.4Gbps, or about 18GB (Gigabytes) for just one minute of content. You're not going to see that.
