For Nvidia cards, you need to download NVIDIA GeForce Experience and update the drivers. This software controls all the HD aspects of your video card and until the software is installed, all of the features of the video card may not be enabled. You need to make sure you download ATI Catalyst software for your video card. Let’s say you have an ATI Radeon HD card and you’re having the lag issue.

If you have a fairly good system with a video card that supports high-definition playback, but you’re getting significant lag when playing videos, it could simply be a problem with your driver or the settings being incorrect.

The second thing to check is your video card drivers and software. Go to Options – Playback – Output and choose a different one.

For example, try uninstalling K-Lite Codec Pack if you have that and install the CCCP (Combined Community Codec Pack) instead.Īlso with Media Player Classic, you can change the renderer and see if that helps. If you’re using something like Media Player Classic, then you can try a different codec pack. If that didn’t work for you, then keep reading! Hopefully not! This solution worked for me on my MacBook Pro.

Now try to play your 1080p videos and see if there is any lag. If you go to Preferences or Settings in VLC and click on Input & Codecs, you’ll see an option called Skip the loop filter for H.264 decoding.īy default, it is set to None. One setting you can adjust in VLC Media Player is the post processing routine. Another lightweight player to try is MPC-HC as it supports GPU acceleration too. You can also try other players like KMPlayer, but I have found VLC to be the best. It has a lot of codecs and can handle quite a lot of formats. My favorite for HD video playback is VLC Media Player. The next thing to try is a different media player. So if you have the time, you can try out a program like HandBrake for Windows and Mac and convert your videos to M4V and they will play just fine and still be HD. Playing back AVCHD videos is very CPU intensive and requires a lot of decoding. You can keep the same high resolution, but playing certain formats is just plain easier and require less resources. For example, if your videos are all in AVCHD format, you can convert them to m2ts or a different format like MP4, etc.

If you don’t mind, you can also convert your videos to another format. However, if you are using the GPU that is integrated with your CPU, then it can be helpful. You don’t need to do this if your computer has a dedicated graphics card. And just change the priority for the process of your video player, i.e. I do not suggest changing it to real time as that can cause more problems than fixes. Once you have closed down as many programs as you can, then try to play the video.Īlso, you can try changing the priority of the video player to High so that it gets more of the processor power. Since your CPU will be mostly utilized playing the HD file, it will lag if the CPU has to keep switching to another process on your system.Ĭlose down all programs and shutdown any unnecessary startup programs that may be running in your taskbar, etc. The second easy thing to do is to make sure that nothing else is using up resources on your computer. If you are connecting an external drive over USB 1.0/2.0, then your videos will lag no matter how fast your graphics card is! System Resources However, nowadays, it’s best to use a solid state drive, which is way faster than a traditional hard drive.Īnd if you simply can’t fit them on your computer, then they should be on an external drive that is connected to your computer with a fast connection like Thunderbolt, USB 3.0, Firewire 800, eSATA, etc. My suggestion would be to upgrade to at least a 7200 RPM drive. In those cases, the videos may lag because of the slow hard drive. Then the hard drive could be a bottleneck. The only time it would be better not to use your hard drive is if you have one of those 5400 RPM drives. For the fastest possible playback, you need to keep the files locally on the hard disk.

One reason the video was playing slowly on my Windows machine was because I had copied all the videos over to my NAS and was playing the files from there. If you have figured out something else not mentioned here, feel free to post a comment and let us know! File Locationīefore I get into any technical stuff, the first thing you should check is the location of your video files. In this article, I’ll go through all the different methods you can try to get your system to play HD video smoothly. However, if you have a semi-decent video card with a reasonable amount of memory and at least a dual-core processor, there are ways to get your machine to play HD videos smoothly. Why? Because it takes an a large amount of system resources to play high-definition videos.
