V této funkci se podívám na to, jak začít s videem. Nic přepychového, ale dost na to, aby kdokoli s fotoaparátem, telefonem nebo jiným zařízením s podporou videa mohl začít a zachytit něco slušného.
Ať už je to fotoaparát nebo telefon, video je nyní významnou funkcí, a přestože se to může zdát trochu matoucí, když začínáte, netrvá to dlouho, než se spustí.
Přestože nyní existuje technologie pro natáčení velkolepého blockbusteru pomocí mobilního zařízení, mnoha lidem se nedaří zachytit pár sekund slušného záznamu.
Pojďme se tedy podívat na základy a zjistit, co dělá skvělé videozáznamy, a podívat se na hardware a na to, co je potřeba.
Zařízení s podporou nahrávání videa
Dnes existuje mnoho možností, pokud jde o natáčení videa, takže se pojďme podívat na možnosti.
Videokamera
Na prvním místě je videokamera. To v posledních letech poněkud upadlo v nemilost, ale pokud je vaše věc natáčení, pak s jedním opravdu nemůžete udělat chybu. Tento článek je však pro ty z vás, kteří teprve začínají a chtějí ze sady, kterou již vlastníte, vytěžit maximum.
DSLR, CSC nebo Bridge pro video
Většina těchto typů fotoaparátů má nyní možnost natáčet video. Mnoho profesionálních fotografů používá fotoaparáty jako Nikon D850, Sony Alpha 7S MKII nebo Panasonic GH5S, zatímco vlogery a bloggery přitahují Canon G9 a Olympus E-PL9 pro jejich snadné použití.
Akční kamery
Tyto kompaktní fotoaparáty dokážou zachytit video v kvalitě, která konkuruje mnoha zrcadlovkám a CSC. Mohou také nahrávat v místech a scénářích, kde by žádná jiná kamera nemohla přežít. Nenechte se zmást malými rozměry, jedná se o impozantní zařízení, jako je GoPro Hero 6 Black, které se často používají pro vysílání a skvělé živé vysílání Yi 4K+ pro vlogery a blogery.
Mobilní telefon
Váš mobilní telefon je s vámi každý den celý den a je nejpoužívanějším zařízením pro záznam videa na planetě. Stejně jako akční kamery vám i mobily umožňují natáčet video na místech, kde byste za normálních okolností nemohli natáčet. Opět platí, že jako některé akční kamery mohou živě streamovat, ve skutečnosti některé dokážou téměř vše, co kterákoli z větších kamer.
Existuje tedy bohatý výběr a je pravděpodobné, že budete mít po ruce alespoň jeden, pravděpodobně dva.
Selecting which mobile to use comes down to what you’re most comfortable with, today you can get great results from most, so let’s see how to get started using the most common, the mobile phone.
How to get started with video on an iPhone
iPhones and for that matter, almost all mobile phones can shoot video, and the quality is superb for the most part.
A few tweaks to the settings can help ensure you capture the best quality footage so let’s get started.
- Select the iPhone camera
- At the bottom of the screen, swipe the options right to select video
- Check the lens is clean
- Hit the red button to shoot some video
- Hit the red button to stop filming
All simple so far, and to be honest this is as far as most people get, but there is more.
Let’s take a look at the resolution and framerate options. If you’re not familiar with these two terms then:
Resolution =Dimensions of the video
You’ll have heard of 4K and HD, this refers to the resolution of the video. And when you look at the options, you’ll see these options listed. It can get a little confusing with all the numbers, and we’ll not look at those in full here, all we’re interested in is 4K and HD.
iPhone resolutions in brief:
- 4K =3840 x 2160 pixels
- Full HD =1920 x 1080
- HD =1280 x 720
What video resolution should I use 4K, Full HD or HD?
If you’re just starting out, then I would recommend filming in Full HD. This resolution is more than enough to playback on large format TVs, on the web or most other video outlets including YouTube and Vimeo.
Full HD also takes up less storage on your phone than 4K and is a little more future proof than HD.
Another factor is that editing 4K video requires far more processing power. Although 4K recording capability is pretty widespread, viewing it is another matter – though 4K TV sales are doing well.
However, there are plenty of benefits to shooting in 4K aside from the increased resolution. For example, the larger image size enables you to recompose the shot when downscaling to Full HD for the final output.
But as we’re just starting out with video, lets keep things simple and stick to 1080p Full HD.
What frame rate should I use to film on my iPhone?
Taking the iPhone as an example when you look at the Full HD options you’ll see you have a choice of two framerates either 30fps or 60fps.
This value refers to the number of frames that are shot in a one-second time frame.
The premise is the more frames per second, the smoother the footage you shoot. Taking that into account, shooting at 60fps will ensure that you have ultra smooth motion in your video.
You may think that shooting at 60fps, therefore, makes sense, but there is a quality drop as the data for each frame is reduced. In most situations, that’s not an issue, but it’s something to consider.
You may see the quality of the footage drop at 60fps compared with 30fps as there will be half the data captured per frame at 60fps over 30fps. This can be seen in the video as slight image break-up or pixelation.
Also, the eye and mind are easily tricked, and 30fps is more than enough to fool the mind – it’s a trick that has been used since the concept of the film and is known as persistence of vision.
In the iPhone video settings you can see the break down of the different file sizes that will be created for each frame rate and resolution;
- 720p at 30fps =40MB
- 1080p at 30fps =60MB
- 1080p at 60fps =90MB
- 4K at 30fps =170MB
There’s an easy way to decide which frame-rate you’re going to use. If you’re filming relatively static scenes or friends and family, then stick to 30fps as you’re unlikely to need the additional frames to capture footage that looks smooth.
If you’re shooting moving subjects, then increase the framerate to 60fps.
There’s also a difference between recording frame rate and playback frame rate.
The iPhone, for example, will play back your footage shot at either 30fps or 60fps at the same frame rate that you recorded.
The standard playback rate for Full HD video is 30fps, so with 60fps footage, you have the option to slow that footage down so that it is stretched over 2 seconds to create smooth slow-mo footage. Try the same with 30fps footage, and it will look all jerky as you are in effect dropping the frame rate to 15fps which is not enough for that all-important eye-fooling persistence of vision.
We’ll take a look at slow-mo in another article.
What frame rate should I use and when?
- Static subjects =30fps
- Moving subjects =60fps
So starting out, lets select 1080p @ 30fps
The final thing you need to do before starting to film is to check that you have cleaned the lens.
This may seem simple but the majority of bad footage is due to a dirty lens especially with mobile phones.
A je to. You’re ready to shoot some footage. But before you start, here are a few additional tips that we’ll expand upon in the next features.
- Lighting:make sure that you shoot in bright conditions
- Try not to film into the sun
- If you need a little fill light, try switching on the camera’s light
Once you’ve shot your footage, you can then edit either on the phone or on your computer.
Here are a few video editing packages we would recommend to get started.
- iMovie (Mac)
- Premiere Elements
- PowerDirector
- Světlo
- Da Vinci Resolve
