Is there a way to trim VLC without losing quality? Of course! Trimming VLC videos without losing quality can be a bit frustrating sometimes. Fortunately, there are applications available that can help you edit videos without losing quality. Wondershare Filmora is one such software that can be downloaded for free. You cannot miss it.

In this article, we will introduce why trimming VLC videos will result in loss of quality, then recommend 3 video editors trim high-quality video without lowering the quality.

Section 1.  Why trimming VLC videos will result in loss of quality?

To understand quality loss, you first need to understand codecs, containers, and video re-encoding. This might get a little technical, so keep sipping that coffee! 

  • Codec 

Every video has a codec and a container associated with it. A video codec is an order in which the video data is organized for playback, editing, and other functions. There are lots of different types of codecs, and each of them has different functions and advantages.

  • Container

A container is responsible for holding video data and other information in a single file. Containers have file extensions like .mp4, .avi, .mov, etc. Some containers can only hold videos in one specific codec, while others can hold multiple codecs. Containers are also responsible for telling media players whether a video has audio or not.  

Why are codecs and containers so important? Imagine if you watched a 1080p video (codec) on an old TV (container) – it would work, but would you really be interested in seeing it? Probably not. A mismatch between containers and codecs can result in poor quality, which is why you must shoot your videos in the right format and play them on the right platform.

  • Video compression and re-encoding

You might be wondering at what point of the whole process does the video loses quality. When you capture the video, it is of the highest quality. As soon as you compress it to share it online, some quality loss occurs, even if you convert it into a high-quality video.  

When you export a video that’s already been exported, you re-encode the video. Re-encoding a VLC video can result in even more quality loss.

The truth is, you can’t reduce the video size without losing quality no matter what you do. If you’re editing a video shot in 4K, but you export it in 720p, the video will become compressed, and the original data of the video won’t get transferred to the new video, resulting in a pixelated block of mess. 

When you make changes to a video with a video trimmer app, you’re changing the data structure that holds information about the video. Why do VLC videos that are small in size appear pixelated and blurry? It’s because they don’t have as much information as videos with larger sizes.

2. Trimming VLC through LosslessCut

It is user-friendlier than Filmora – all you have to do is drag your video to the software and then you can start trimming it by using the Arrow symbols.

  • Pros: LosslessCut works best with mobile videos or action cams like GoPro.

3. Trimming VLC via TunesKit Video Converter

TunesKit also has a video editor, which lets you add effects to different segments of the trimmed video, a feature that you probably won’t be using very often. To trim VLC videos in MP4 without re-encoding, you simply have to drag the slider that appears when you import your video. 
  • Cons: However, its functions may not be as rich as Filmora
