4K resolution, also known as 4K, is one of the new trendy tags coming into people's sight in recent years. It’s a newly-emerging resolution standard for Ultra HD, which provides with the ultimate visual experience. With the growing demand of the public, as well as the extraordinary advantage of 4K, it may probably become the mainstream standard for digital video in the next couple of years.
Why Do We Need to Compress 4K Video?
Limited by many realistic factors (like storage, devices, Internet technology and etc.), 4K video is still such hot potato nowadays. For example, if you happen to get a 4K movie file on the web, it will be a problem for you to download it to your hard drive. An original 4K movie is normally more than 200 GB, which means you can keep 10 copies of 4K resolution movies in your 2TB hard drive at most.
With no doubt, it is a stunning experience to enjoy the visual feast of 4K video! Considering about the conflict between the lagging device support and the rapid development of 4K technology, a majority of mainstream devices are unable to do a good job on playing 4K video, like iPad, iPhone and other Android smartphones.
Obviously, 4K movie is not the ideal choice for the public at the present stage. So the best solution for this type of file, if you’ve got a 4K movie video, is known as 4K video compression.
How to Compress 4K Video in the Best Quality?
Three effective means to optimize & compress 4K video:
1. Convert 4K video to 1080P or less
4K video file is very huge in size, and you can optimize it for your device by scaling it down to 1080P full HD resolution. After the compression, you can not only get the acceptable size, but also make it good at playing on portable device. It’s the good way to reduce video size without quality loss. but keep its high definition. We can convert video for iPad, and thus you can play 4K video on iPad anytime and anywhere.
2. Optimize with the superior encoder H.265
As we know, most 4K videos are in H.264, the widely-used encoder currently. H.264 is very steady but low compression. Therefore, here comes H.265 as its successor.
H.265 (also called HEVC) is a new advanced HD video encoder, which leads to a smaller size but better quality. It’s the best choice to compress 4K video by optimizing the video encoder.
3. Reduce the bit rate
It’s the most direct way to cut down the video size. You can define the bit rate according to your need, but it will lower the video quality by reducing the bit rate.
