Ultra HD video is finally hitting the mainstream, as the demand for higher quality video is met by the arrival of new products that can take us from the era of 1080p full HD video into one of cinema-quality 4K. On the one hand, we're seeing growing numbers – and sales – of 4K TV sets. Laptops, tablets and even smartphones are also going beyond 1080p to cover resolutions of 2048 x 1536, 2560 x 1440 and beyond, all the way up to the full 3840 x 2160 resolution of Ultra HD. 4K sources are finally coming online, too, whether YouTube, streaming video services like Netflix and Amazon or the 4K videos we're shooting with our smartphones, DLSRs and action cameras. Every is in place for a 4K revolution.
However, we may have to compress our 4K videos
As a result of high bit rate and huge size, 4K video brings a big challenge to consumers' media-playing devices and programs. Your hardware configuration such as processor and graphics card should be powerful enough to crunch the data and your video player software should be compatible with the super ultra-high-definition. Otherwise, you'll have problems with 4K video playback, coming across lagging, jerky, choppy, stuttering and the like. And besides, encoding 4K videos with HEVC and VP9 both of which are not yet universal also contributes to the difficulty in playback.
A 60-second 4K H.264 video at 30FPS captured with iPhone takes up around 350MB, and 170MB using HEVC. Such large files will eat up your storage space rapidly and slow down the speed of sending via email and uploading to YouTube or something.
Out of smooth playback or out of hastening sharing or other purposes, we need to compress 4K video file, at least for now. Compressing 4K to 1080P is a solution that can reduce file size dramatically and meanwhile guarantee no visible drop in quality when watching on popular displays.
Are most existing compression tools up to the job? Not really. Some simply don't cover 4K files. Others aren't built to cope with them, and will either shrink at a snail's pace or simply hang or crash under the strain. Many of the old standbys that have coped admirably with 1080P files are just too old or slow to update. They're not built to take advantage of modern multi-core, multi-threaded processors and powerful GPUs.
The best 4K video compressor software
As mentioned in the beginning, 4K UHD video compressor from WinX allows you to downsize 4K videos quickly, with minimal effort. As its name indicates, this program is primarily developed as a conversion tool changing video file format from A to B, MKV to MP4 for instance. But you'll be surprised to find that there're some meritorious additional features, 4K video download and 4K video compression.
This tool is able to read 4K HEVC/H.265, 4K AVC/H.264 and UHD videos encoded with other codecs, at 60FPS, 30FPS, etc. Then, compress them to 1080P, 720P or other manageable resolutions. By leveraging Intel Quick Sync Video technology, introduced with Sandy Bridge and enhanced gradually in Ivy Bridge, Haswell, Broadwell, Skylake, Kaby Lake and Coffee Lake, it can speed up video conversion and compression tasks up to 16 times. And if you own a NVIDIA graphics card based on Kepler, Maxwell (1st Gen, 2nd Gen, GM206), Pasal, and Volta, you can also expect to see faster video processing because of the utilization of NVIDIA NVENC hardware acceleration. Where other tools hang-up or crash under 4K workloads, WinX HD Video Converter Deluxe just gets on with it, thanks to supporting hardware-based decoding, processing and encoding. More than that, speed will be well-balanced with quality.
How to compress 4K to 1080P video fast
Once completed, simply follow the step-by-step instruction below to downscale 4K to HD 1080P with optimal quality and size at fast speed.
Step 1. Input the source 4K video for later resizing.
Source files can be added through + Video button at the top left corner or via drag-and-drop. It is available to import multiple files in one effort.
Step 2. Choose output profile.
Output Profile window will appear immediately right after file loading, providing 410+ optimized presets for everything, for example iPhone X/8, iPad Pro, Samsung Galaxy S8, Note 8, Sony PS4, Microsoft Xbox One, iMovie, iTunes, Final Cut Pro, YouTube, and Facebook. Different user needs are taken into consideration. Just select one based on your own needs and click OK to save your option.
Step 3. Specify 1080P as the output resolution.
Click the gear icon and then get access to a smaller window where you can set video audio parameters. Locate Resolution option and click its drop-down arrow to choose 1920x1080. Alternatively, press Customize button and type in 1920 and 1080 manually. Next, hit OK in the bottom.
Step 4. Start compressing 4K to 1080P with hardware acceleration on.
Below the preview window of main screen you should see two options - Intel and nVIDIA. Checking Intel/nVIDIA will power up your hardware accelerator to undertake this processor intensive work for CPU and speed up video decoding, processing and encoding. Next, click the blue RUN button to start downconverting 4K to 1080P instantly.
