4K Splitter: Split 4K Video with Best Free 4K Video Editor Software

4K video is too large for uploading, sharing or transferring? Normally the higher the resolution you choose to record a video, the larger the file size will be.

Taking iPhone as an example. If your iPhone supports HEVC codec, then the file size will be about 170MB when recording a one minute 4K 30fps video. Otherwise the file size will be twice, 350MB, if your iPhone is running in iOS 10 or lower which only supports recording 4K videos in H.264. In regards to GoPro Hero Black, the recorded 4K video file size will be larger. One minute 4K 30fps video encoded in H.264 can be up to 450MB.

You can use a top 4K video splitter, cutter, or editor to flawlessly split large 4K video into small clips for uploading to YouTube, Instagram (Stories), etc. or cut unnecessary parts to make the 4K video smaller. Yet, as for the 4K HEVC iPhone videos, it would be high-demanding on your hardware configurations compared with 4K H.264 or 1080p HEVC. Thus, if you just rely on real-time video editing or the ordinary video editing app Filmic Pro, you would meet Filmic Pro crashing or iPhone freezing issues, for they're powerless to handle with 4k HEVC increased computational complexity. In such a case, only the software with GPU hardware acceleration tech can be the silver bullet.
