Hi This is probably a noob question but I am still learning this . I have a plex server on a Windows computer and also a bunch of movies that are mp4 and mkv’s. The same PC also runs my CCTV system I noticed when I play a 4k mkv the movie would not play smoothly and stutter. Checked my CPU on the …

I am sorry, but I disagree. The container format mkv or mp4 is definitely not the problem. Converting from one to the other, called remuxing, is a operation with little demand on hardware resources. However, you mention “4k.” If - for whatever reason - the server decides to transcode a non-trivial…

Listen to eckarth. He is telling you how things actually work. I have no idea why XxidroxX thinks the container matters with regards to when and why a file requires transcoding, but he may be thinking of remuxing which is what happens when everything but the container is supported. For transcoding i…

From what I have read and experienced, the easiest way to reduce CPU load is to add a display adapter (GPU) that will offload the transcoding burden. I have had good luck with Nvidia card. Got immediate benefit after installing on my Windows PC.

A video card can help, but your mileage will vary depending on the source file as the hardware accelerated encoders don’t support every kind of input. At least that’s what it was like a couple of years ago. They may have improved now.

Thanks for the dashboard dont I also need plex pass? I dont ahve plex pass What If I try test a 4k movie thats mp4 I think I will try that first

yes a plex pass required for gpu transcoding in plex. you can still use other programs (ie handbrake etc) with gpu, outside of plex. but the main point is to avoid transcoding in the first place, which the FAQ linked above will help you understand what to do. (don’t use truehd unless you have a s…

thanks yeh I read that FAQ, Some if it I dont understand but remember I mentioned my CPU was even bottle-necked playing a mkv 1080p file when my CCTV system was running. I guess I could upgrade the CPU as its a bit old and I am asking it to do a lot but if I grab mp4’s it doesnt transcode anything. …
