What the…?What is this, Minecraft?Hey everyone!I’m Trisha Hershberger and in today’sepisode of DIY in 5 we’ll talk about video resolutionand try to make sense of all thoseHD, 2K, 4K, 8K, etc, etc. terms.If our tips help, pleasedon’t forget to subscribeso you won’t miss anyof our upcoming episodes.Let’s start with the easy stuff.What does 1080P, 4Kand all that even mean?In basic terms it’s just the number ofpixels in a given area.We usually talk about itwhen we think of screens.Pixels themselves don’tactually have a specific size.

They’re just individualilluminated components on a screen.So when we say something is 4K we’re sayingthat the max number of pixelsthat the screen supports is roughlyfour thousand pixels wide.Here’s a handy chart which shows you someof the most common screen resolutions.So now you might be thinking, “what aboutTVs which are both 4K but are different sizes?Let’s say one is 50 inches and the otheris 70”? What gives?”The simple answer is the 70” TV is justshowing you larger pixels and that’s ok!In some cases, it’s very ok.Now that we have a better understandingof what resolution is,let’s talk about whyit could be important.We’ll start with filming.

For those of you who still shoot with an actualcamera, and those of us who film from our phones,you will need to set your resolutionbefore filming.Despite what TV dramas show us,you can’t just press an ENHANCE on akeyboard and magically get more resolution.If you want to see your footage in 4K,get a camera that shoots itand make sure you’reactually filming in 4K.A number of phonesand camera will default to 1080P.

Now let’s discuss whatmost of us care about, TVs.Let’s be real, not every TV will benefitfrom 4K or 8K.If you go online you’ll see different calculatorsthat say how big your TV should bebefore upgrading tohigher resolutions.Based on our personal,very unscientific methods,we see 50” TVs as thesmallest size that benefit from 4K.Any smaller than that and it’s really hardto tell that there are actually more pixels on the screen.Hu, I can kind of see the 4K….

As for 8K TVs it’s probably going to bea while before we start seeing those in stores,so we won’t worryabout them yet.Now that we understand the basics,what else do we need to know?Let’s talk about content.There’s still very little 4K content availablefor your big shiny new TV, but it’s getting better.The good thing is, Netflix shoots almost allof their original programming in 4Kso they’re an excellent sourceof super pixel-ey goodness.Some YouTube channels also upload in 4K butnot too many at the moment.If you do want to stream any 4K content it’srecommended that youhave at least a 25 megabit per secondinternet connection.

If you’re more into physical media there’salso 4K Blu-Ray discs, but you will need aplayer that actuallysupports them.Your standard Blu-Ray player from a few yearsago won’t play the new stuff.And finally, for my digital file loving friendsout there just know that 4K video files are huge.So if you want to keep all those ultra-highdef files on your systemyou’re gonna needstorage space.You’ll get roughly 35 hours of footage forevery terabyte of hard drive you have.So who of you has alreadymade the 4K TV upgrade?Do you actually noticeany difference?Let us know in thecomments below.And, you know many phonesnowadays are 4K filming machines!If you want to learn how to shoot better videoon an iPhone, check out this video here.That’s all for now.I’ve got a really large screen togo watch stuff on so I gotta get back to that.That’s not true at all -that was YouTube magic.
