What is a Video Lag and How it is caused?

Firstly, let's cover some basic details about video lags and what could have caused these issues to start with.

What is a video lag?

Ideally, a lag is a slow response by the computer, network, or any application. Therefore, while playing a video, if it isn't getting loaded at the right speed, or has been halted, then it can cause lag in its playback.

Video Lag Symptoms

Most of the video lag symptoms are related to media players when the application takes a lot of time to launch or play the video. Sometimes, even a system-related issue can trigger it. Therefore, if your computer is already running slow or the hard drive is producing a sound, then it can be a symptom of video lags.

What causes lagging in videos?

If you believe that your Mac or Windows system has caused a video lag in it, then you can follow these solutions.

Guide 3: Check your Network or Browser to Remove Lags in Online Videos

Another issue related to video lags that a lot of people encounter is while watching videos online. To fix any video lag due to a network or browser-related issue, I would recommend these solutions.

Fix 1: Reset your router

Well, if you think there is a problem with your network, then your router can be responsible for that. To resolve this, you can reset your router pretty easily. Just hold and press the reset button for at least 10 seconds (located at the back or bottom of the router). After that, wait for a while, restart your router, and connect to your network again.

Fix 2: Adjust the video quality

If you are getting a video lag while playing HD content on YouTube, Netflix, etc. then consider adjusting the output quality. An HD video might take a lot of time while loading and an unstable connection can cause it to lag. You can just go to the settings of the media player and change the output quality to an optimized value like 720p or 360p instead.

Fix 3: Delete the Browser Data

Another reason for online video lags is the accumulated data in browsers like Safari, Chrome, and Firefox. The method to remove their browsing data (like cache, cookies, and temp files) is pretty the same in all applications. You can go to their browser settings and manually remove the saved cache, app data, and so on.

Guide 4: Fix Slow VLC Player Lagging Problems

Although VLC is one of the most popular media players, it can suffer from unwanted lags while playing videos. To fix the VLC player lagging issue, you can try implementing the following suggestions.

Fix 1: Enable the Auto Repair of Videos

You might not know this, but VLC has an inbuilt feature to repair minor issues with AVI files. If you think VLC is lagging because of this, then just launch it and go to its Tools > Preferences.

VLC Tools Preferences

As the Preferences window of VLC Player would be launched, just visit its "Input/Codecs" section. From here, you can choose to always fix the loaded AVI files in VLC Player.

VLC Auto Repair

Fix 2: Skip the loop filter for H.246 Decoding

The H.246 decoding is an inbuilt feature in the VLC player that is particularly used to apply filters to decode certain videos. Though, if the feature is enabled all the time, then it can cause unwanted video lagging on the laptop as well. To fix this, you can just go to its Tools > Preferences > Advanced Preferences. Now, under the "Skip the loop filter for H.246 decoding" just select the "All" option and save your changes.

VLC Skip H246 Encoding

Fix 3: Disable Hardware Acceleration Decoding

VLC Player also has another feature that can calibrate with GPU processing while playing videos. Too often, it has been observed that the hardware acceleration can result in VLC Player lagging. You can fix this by visiting its Tools > Preferences > Input/Codecs section. Here, look for the hardware-accelerated decoding feature, and simply disable it.

VLC Disable Hardware Acceleration

Fix 4: Update your VLC Player

If it has been a while since you updated your media player, then you can encounter the VLC lagging problem as well. You can just launch VLC Player and go to its Help menu to check for updates. This will automatically make the media player look for any current update and let you complete its installation.
