4K: What you need to know? Do I need a new computer for editing 4k video?

Summary: In this article you will learn the basics of what 4K is and what you'll need to work with 4K footage.



4K: What you need to know?

The name 4K is used to describe a couple different, though very similar, standards. 4K is a video specification that literally just means '4,000'. It gets its name from the approximately 4,000 pixels of width of the footage. The form you're most likely encounter is Ultra High Definition or UHD, the new standard for 4K television. 4K video is poised to become the new benchmark for both recording and watching video and it brings a whole host of benefits, right away.

You've probably already noticed the jump from pre-digital 'standard definition' television up to 'HD' and 'Full HD' services that are now available on digital TV, online streaming and Blu-Ray discs. Compared to earlier standards, this HD footage is detailed, crisp and it even looks good when viewed on a large TV. But even the best quality, '1080p' HD footage is only 1920 pixels across. 4K is significantly more detailed, since it has twice as many pixels horizontally, and four times as many pixels in total.

Do I need a new computer?

Apple's Mac Pro desktop computer is more than enough to handle 4K editing, compare with an iMac/Mac Pro, or even with the new computer, to handle 4K workflows effectively, you would have to add-on a Thunderbolt expansion chassis with a RED Rocket card or RED Rocket X card, at least one or two powerful graphics cards such a the GTX 680, and a beefy Thunderbolt RAID like a Promise Pegasus 6-drive model.

That is to say, there is unfortunately no way you will be able to edit native 4K files at any of the higher quality, lower compression rates. The only way would be to transcode to a lighter codec, such for Adobe Premiere, the best compatible format or codec is MPEG-2, for Final Cut Pro, the best compatible format or codec is Apple ProRes(Apple ProRes Codec Types), for Avid, the best compatible format or codec is Avid DNxHD(*.mov). Well…yes, if you convert to those compatible original format and scale to 2K for editing. 

The best solution to edit 4K video is to convert 4K files to those compatible original format for each editor. Pavtube Video Converter / Mac Version may help you a lot on this convert part, this is the top 4K video converter on the market, it can convert any 4K videos recorded by Red 4K camcorders, Sony 4K camcorders, Panasonic 4K camcorders, Canon 4K camcorders, JVC 4K camcorders, etc. to compatible original format for each editor.
