[4K Video Processing] How to Convert, Compress, Edit, Play 4K UHD Videos

Posted by Bella to 4K UHD Tips, Video Converter Reviews | March 22, 2018

Is there a 4k video converter that can do 4k video processing all at once, such as convert, compress, edit and upload large 4k ultra HD videos without any problem? Check the answer here.

With the era of HD having been shifted to 4K Ultra HD, 4K videos finally rule the roost. Resolution of such video can be either 3840x2160 or 4096x2160p that allows for much more details than HD 720p/1080p. The great leap from HD to 4K Ultra HD makes everything clearer and crisper. This leads to widespread existence of 4K videos. They can be found everywhere, be it on YouTube, Netflix, 4K TVs, monitors and projectors, gaming systems, Blu-ray discs, or shot with iPhone, DJI drone, 4K camcorders such as Canon XC10, or action cameras like GoPro Hero 6.

Part 1: What is 4K Ultra HD and 4K Video Resolution?

4K, generally referred to as Ultra HD, is a professional production and cinema standard with a horizontal screen resolution in the order of 4000 pixels. 4K UHD quadruples the HD resolution of 1920x1080 to 3840x2160. In 2013, Sharp showcased world's first 8K TV at CES event. This means a wild leap taken from 4k to 8K, which forms the total image dimension of 7680x4320, twice the horizontal and vertical resolution of 4K UHD. However, 8k is still under development, and 4K is set to be the new standard of video format with a more sharply detailed image quality.

Part 2: How Can I Play, Edit, Upload HD Videos without Any Limitation

As more pixels are crammed in 4K compared to HD, images get sharper and clearer. So you want to show off 4k shootings, store more 4K videos in smartphones, enjoy 4k contents across all platforms, turn your 4k recordings into a film-like masterpiece. There are occasions you want to do more with 4k UHD videos.

You want to
play 4K UHD videos

You want to
reduce 4K video file size

You want to
edit 4k video records

You want to
upload 4k shootings to YouTube

However, there are pains with 4K and 8K. Both of them ask for high requirements on the computer hardware. Videos in 4k or 8k may pose problems such as crash during playback due to the video resolution issue or if on a computer with old graphics card. This is not the end, there are still many other problems and questions with 4K Ultra HD video files, when you go a step further with 4k UHD videos.

"Just want to keep all my 4K movie downloads in the same format that my Macbook recognizes, how to realize this?"
"Get an error Unable to play video because the file format is unsupported when playing the video on iPhone, how to fix it?"
"iMovie won't import the video from DJI Phantom 4 Pro? Always says it doesn't support file type. What am I missing?
"Get a pixilated result when watching 4k video on HD display? Any suggestion?".
"4K videos takes up too much space, how to reduce the file size to store them all?"
"Too slow to upload YouTube videos. What should I do?"
……

Don't worry, you can make the ideas into reality by 4k video processing, converting, compressing and editing. To realize the tasks, a 4K video converter is a must-have. Generally, the software will help you:

convert 4K video to any format

1. Convert 4K videos to fix format issues

Formats of 4K videos can be poles apart. For example, a YouTube 4k video can be formatted in either FLV, WebM or 3GP that your iPhone may not recognize. iPhone 4K video in hevc codec is still out of reach by Android phone. Camcorders videos are generally saved in AVCHD MTS that both Windows and Mac users will run into format issue. Some programs are nitpicks at video frame and resolution with the source 4k videos. These are good reasons why you need a good 4K video converter for Mac or Windows to fulfill the video process of converting 4K MP4, MKV, FLV, AVI, WebM, or other files into the format and resolution that your device recognizes.

compress 4K video to smaller size

2. Compress videos to store more 4K videos

Generally, a 1 min 4k resolution video at 30 fps steals over 375MB of free space, while 18-hour videos shot by DJI P4P will eat up Mac's 512GB hard drive space. If you want to store more 4K video files on a space-constrained smartphone or a cloud service, doing a 4k video size reduction for fear of occupying too much space is essential. Common 4K video converters involve the process of media processing, decompressing and compressing. H.264 is the best video compression standard that balances the file size and quality greatly. But now its successor HEVC promises 50% storage reduction while maintaining high quality. So we suggest you either change the video codec to H.264/H.265 or lower video resolution, bit rate, framerate to compress 4k videos on Mac and Windows PCs.

4K UHD videos editing

3. Edit Videos by cutting, trimming, merging and more

Shutterbugs are high on going extra miles with their recordings. They need to edit them into a masterpiece, such as cut unnecessary content like ads, split the video into smaller pieces to extract the favorite part, edit out the flawed or unwanted bits to reduce the 4K UHD video file size, merge multiple recordings into one, simply shorten the long video length, watermark the footage to make it personalized, add effects, graphics or music. Of course, doing the 4k video editing can be done with a computer, if configured with good CPU, GPU, RAM with at least 32 GB RAM, and more. But if you are budget-restrained, why not just seeking a 4k video converting tool with editing feature to make your shootings into a professional-looking home movie.

upload 4K video without limitation

4. Upload HD videos without any limitation

YouTubers or bloggers are bound up in uploading their funny videos, game videos, tutorials, vlog, etc on YouTube or their web sites for sharing. But these video hosting sites set up a barrier for each video upload. For example, video length is restricted within 15 minutes and formats in MP4, MOV, AVI, WebM, FLV and 3GP are supported only. But with a video converter for Mac or Windows, you can change the video format to YouTube supported ones and edit out the unwanted parts within allowed length. By the way, converting 4k UHD to lower 1080p or 720p video is helpful for faster YouTube uploading, and viewers will therefore consume less traffic and stream video smoothly.

Part 3: Common Problems with HD/4K Video Converting Software

Frankly, most 4K video converters are up to the jobs. Some can even upscale HD to 4K available for users who are unbearable to the pixilated HD/SD contents. But the end results vary greatly, or even daunting. Some tools output large files and blurry images. While some convert at a slow speed or even crash under the strain. This is because 4K video encodings are more CPU intensive and time consuming, and ask for higher demand on the computer hardware than HD conversion.

Part 4: How to Convert HD/4K Videos at Fastest Speed and High Quality

Is there any video processing tool to deal with 4K UHD videos without such problems? As stated, sorts of 4K UHD video transcoding issues keep intruding. Generally, users are unlikely to replace the hardware equipment specifically to get around such problems alone. So all their hope is that a 4K video processing tool could handle 4K Ultra HD resolution videos with no errors but fast. MacX Video Converter Pro is exactly what you want to hear about 4K UHD video converter, which processes 4K UHD videos to smaller size up to 70% compression ratio, without any loss of quality, in 5 times faster speed than any other converters. For example, to process a 4m29s 4K video, MacX merely calls for 1 minute to compress it from 4K to 1080p, while for Handbrake, 6m42s are needed to get it done.

How MacX Achieves Such a Fast 4K Video Transcoding Speed without Quality Loss

fast 4K video processing

The reason why MacX runs in a speed far ahead of Handbrake and other 4K converters lies in the hardware acceleration technology mostly. As you're processing 4K UHD videos with MacX, the Intel QSV tech built into Core i5/i7 Mac processors, or the NVIDIA® CUDA™ and AMD® GPU acceleration tech could accelerate 4K video processing as it runs on thousands of GPU cores in parallel, rather than the sequential part of the workload running on the CPU. Thus, to convert a 4K video to 1080p with the same settings, the hardware acceleration supported V6.3.0 runs 3-5 times faster than regular conversion.

As for other hardware acceleration enabled tools like Handbrake, AVC, Wondershare, and Movavi Video Converter, the test shows MacX still runs an incredible fast speed than all its competitors.

Test: Convert 4K MP4 to 1080p with Hardware Acceleration Enabled

Input: MP4 format, AVC codec, 497MB file size, 4m29s duration, 3846 × 2160 resolution

Output: MP4 format, H.264 codec, 1920 × 1080 resolution
