4K videos are available everywhere, from the cameras to TVs, games consoles to laptops. 4K wins its popularity for much sharper picture and higher definition it brings, especially on large screen. While 4K UHD is usually featured with HEVC codec in large file size, which causes kinds of 4K video playback errors, such as 4K stuttering/choppy, video codec not supported, up to 100% CPU usage, overheated computer, or 4K HEVC frame drops etc. Actually, 4K video playback errors go far beyond these. Some typical errors are listed as follows.

Take an iPhone recorded 4K video as an example, 1 hour of 4K HEVC at 60FPS consumes about 23.4GB.

Bonus Points:

  • NVIDIA NVENC is enabled for conversion acceleration.
  • Additional features DVD ripping, video downloading and recording can be enjoyed.

But: Personal experience tells that this 4K video converter not works as fast as we imagine, it takes about 20 mintues to convert an hour 4K video. What's more, because it only supports NVIDIA GPU-acceleration, you can't get a fast conversion if your computer doesn't have NVIDIA graphic cards.

• XAVC Video Converter

Part 4: FAQs for 4K Videos not Playing/Converting/Editing

Q1: I have video in 4k h265 codec that I make with my Sony XZ Premium mobile phone. I convert them to 1080p with Handbrake. After converting I try to add video file to Adobe Encore to make bluray ISO or bluray folder, but now the problem start because Adobe Encore are doing some transcode and after that I have audio video desynchronization. I don't know what is going on with that video file.

A1: That's because your Handbrake converted 1080p video may set "variable framerate" (vfr). It'll be fixed after yo re-convert with constant framerate. You can try WinX HD Video Converter Deluxe to do so, as Handbrake has some issues with 23.976 and 59.94 framerates that when you select constant frame rate you do not get a true constant frame rate. Learn more about how to use Handbrake >>

Q2: I'm trying to recode an x265 file which bitrate is too high for my device. I choose H265-10bit. The dimension tab shows that the source is 3840x2160, and starts with a 1920x816 odd setting, but I cannot go above 1920 for the output. I'd like to set it to 3840x2160. What am I doing wrong?

A2: Resolution is probably limited by the selected preset. You can create a new one which allows higher resolutions.

Q3: I want to do a loss less 4k trim of a mp4 file but it only gives me a mkv file. I want the output to be a mp4 file. my editing program doesn't accept mkv.

A3: You can convert 4K MKV to MP4 in advance, and it will be imported to your editing software smoothly. Or you can try a free video converter, which is able to convert 4K to MP4, as well as trim 4K video clips easily.

Q4: I have downloaded a high quality high bitrate 4k Demo from this site. The problem is none of the players I have play this video smoothly. There is a massive lag. I have tried VLC Player, PotPlayer, KM Player, MPC, to no avail. POWER DVD is the best player I have tried so far, but I still have the lag. What player should I try? I'm runninng a workstation with two GPUs (Nvidia GTX 960M 4Gb + Intel Graphics 4600 2Gb), 12Gb RAM, i7 4720 2.60 Ghz CPU.

A4: The problem is that neither of your graphics adapters can provide hardware decoding for HEVC and the i7 4720HQ in your laptop is not powerful enough to decode 10-bit 60 fps UHD H.265 video using software. There are two options: replace your computer hardware with better ones or convert HEVC to H.264 with a HEVC video converter.

Q5: Hello, i like the smooth motion of 60fps movies. Know everyone here how i can convert 4k x265 movies to 60fps? By 1080p i convert this with MeGUI and Interframe. But this is not working with 4K and x265. Can anyone help me, how i can easy convert my 4K movies to 60fps? Thank you!

A5: You can try WinX HD Video Converter Deluxe, which allows you to change 4K frame rate to 60fps within 4 steps: load 4K video > choose output format > upscale 4K frame rate to 60fps > click RUN to get everything done.
