00:00:00.080 --> 00:00:05.240
everyone knows hd and retina they

00:00:03.360 --> 00:00:10.639
marketing terms that mean better image quality but they're only about the

00:00:07.480 --> 00:00:12.679
resolution or the fineness of the image

00:00:10.639 --> 00:00:18.760
see that right there that mess you're looking at is a high resolution hd image

00:00:16.000 --> 00:00:22.119
but with very low color depth color depth is incredibly important if you

00:00:20.359 --> 00:00:27.359
want to experience your content the way the creator intended color depth refers

00:00:25.199 --> 00:00:31.920
to the amount of data that can be used to indicate the color of each dot or

00:00:29.480 --> 00:00:37.399
pixel on your display one bit would be black and white two bit would be shades

00:00:34.079 --> 00:00:40.320
of gray and 8 bit allows a 256 color

00:00:37.399 --> 00:00:44.800
palette in short more bits of color depth bring translations into more colors that

00:00:42.239 --> 00:00:49.440
can be displayed so on the bits well there are challenges processing

00:00:47.199 --> 00:00:54.559
power on cpus and graphics cards used to be a bottleneck and while today they're

00:00:51.440 --> 00:00:56.760
fine for a high quality image every link

00:00:54.559 --> 00:01:01.320
of the chain needs to be high quality challenge number one is data storage and

00:00:58.920 --> 00:01:06.439
internet bandwidth Digital files with high color depth are really big to save

00:01:04.199 --> 00:01:10.920
space and bandwidth usually they get compressed websites like youtube

00:01:08.880 --> 00:01:16.280
streaming services like netflix and even your cable tv provider are all serving

00:01:13.720 --> 00:01:20.720
highly compressed video which negatively affects color fidelity you will often

00:01:18.720 --> 00:01:24.400
easily detect where the approximations are being made where the creator

00:01:22.360 --> 00:01:29.680
intended for the colors to blend smoothly together but instead you see

00:01:26.560 --> 00:01:32.000
blocks or bands of the same color

00:01:29.680 --> 00:01:37.119
because to save on infrastructure costs much of the data has been lost challenge

00:01:34.439 --> 00:01:41.680
number two is display let's say you py up for a blay of your favorite movie and

00:01:39.320 --> 00:01:47.159
then watch it on a cheap tv or tn panel monitor in this case the data is all

00:01:44.360 --> 00:01:51.119
there but your display is not capable of reproducing all those colors so you'll

00:01:48.759 --> 00:01:57.039
see the same block and color banding as before where the display is just

00:01:53.119 --> 00:02:00.960
approximating the as best it can right

00:01:57.039 --> 00:02:02.840
let me straight telling my ‏su when i

00:02:00.960 --> 00:02:06.119
was perfectly happy with it before and then you're following up by telling me

00:02:04.880 --> 00:02:13.040
there's basically nothing i can do about it without spending ach money anyway are you trying to make me unhappy no i'm not i

00:02:10.560 --> 00:02:17.480
know all of this and i'm still perfectly happy in you know canada here with my

00:02:15.879 --> 00:02:21.959
canadian internet connection and you know canadian netflix it especially

00:02:19.959 --> 00:02:27.280
doesn't bother me on small screens like on a phone or a tablet and in vibrant

00:02:24.519 --> 00:02:30.959
scenes with many varied colors it only really bugs me in dark scenes with many

00:02:29.120 --> 00:02:34.959
similar colors i mean see that right there the block and lack of detail in

00:02:33.400 --> 00:02:38.560
the bunny when he covered by the shadows is a perfect example of what we're

00:02:36.480 --> 00:02:42.239
talking about and just because we're aware of this and understand it better

00:02:40.560 --> 00:02:46.159
doesn't mean we have to change anything i just wanted to cover this topic for a

00:02:44.200 --> 00:02:51.640
while so that i can explain to folks way why their ht image doesn't look that

00:02:49.599 --> 00:02:55.840
great if they always look that great do want to do something about it they'll know what to

00:02:53.239 --> 00:03:00.920
do look for content that uses high quality codex and is encoded at higher

00:02:58.519 --> 00:03:04.959
bit rates the higher the bit rate or the amount of data per second in the

00:03:02.680 --> 00:03:09.200
video stream the higher the color depth is likely to be try higher quality

00:03:07.040 --> 00:03:13.640
content first before upgrading your display and use shadows as a quick and

00:03:11.720 --> 00:03:17.239
easy benchmark to see if it's making a noticeable difference and if it doesn't

00:03:15.599 --> 00:03:21.519
make a difference to you then that's great because there is a limit to what

00:03:19.080 --> 00:03:26.480
your eyes can see anyway before More color depth really doesn't make any

00:03:23.080 --> 00:03:28.120
difference speaking of shadows our

00:03:26.480 --> 00:03:32.439

00:03:53.200 --> 00:03:58.560
mean i guess i could have gone with like heart of darkness or like book of

00:03:56.640 --> 00:04:01.799
shadows actually don't know if there's a real book of shadows it's just

00:03:59.799 --> 00:04:05.840
something that's in like every fantasy novel ever there's always like a book of

00:04:03.480 --> 00:04:09.319
shadows anyway i seem to have lost track of what i was talking about make sure
