How to Cut TS Files with Video Cutter?

Part 1: What is TS File?

TS, fully named as MPEG2-TS, is a format container. In this format, any part of the video streams is independently decodable. Another similar format is MPEG2-PS which is used to store DVD videos.

MPEG2-PS is mainly used to store programs lasting the fixed duration (i.e. DVD movies) while MPEG2-TS is applicable to real-time televising programs (i.e. broadcast). Do you know what is different between these two formats?

Let’s see an example. If you cut off half of a VOB file, the file cannot play anymore. Yet, you can watch TV programs at any time as long as you turn on a TV. That is the point. Any part of a MPEG2-TS file can be decoded independently.

Besides, m2ts is included in the TS format. M2TS is a high-definition video format fabricated by MPEG-4 AVC/H.264 video coding. This format can contain clearer videos than MPEG-2 but also support to process multiple video streams simultaneously. Yet, M2TS is not the standard format for DVD or Blue-ray Disc. If a M2TS should be burned into a DVD, it should be converted to the other formats.

Part 2: How to Cut TS Files with Video Cutter?

Renee Video Editor can detect the target videos and take priority to lossless editing.

If the formats or the resolutions are not identical, it can recode the videos but not degrade the quality. It is very convenient for users because they don’t need to use the complex coding tools to reset the video parameters.

Cut Video by Time

The cutter in Renee Video Editor can process TS files for batches by time and by size. Users can use it to quickly divide a large video into small videos clips with equal size or length. Importantly, this software has no limitation with the video size.

If you want to divide a 5-minute video into several 1-minute videos, the function [Limit each segment to time] can help you split the clips.

Cut Video by Size

What should we do if a CD cannot hold a multi-GB TS file? You can divide it into some pieces and put them into several CDs. The cutter in Renee Video Editor can help you split a TS file by size.

Split Averagely

If a TS file is too large, it will not play fluently in the low-configured computer. Yet, if you averagely split it into several clips, the audio and video quality will be better.

In addition, in Renee Video Editor, you can add various special effects, watermarks, music, subtitles and opening/ending to make an attractive video.

Part 3: Notes about Cutting Video

When using a video cutter to process a TS file, you may meet with these cases:
1. The video and audio quality is declined.
2. The images lag behind the audios in the split video.

If you want to solve these problems, go to learn about the following parts!

Difference between Lossless Cut and Lossy Cut

Lossless cut: It means that a video is edited directly. This way will not degrade the audio or video quality because it skips the process of recoding.

Lossy cut: It means that a video is encoded again and then edited. Generally, the coding way is lossy compression in a video. If the video is encoded again, the audio and video quality will be degraded.

Any Problem in Lossy Cut?

We can treat a video as a collection of bitmaps. If the bitmaps are large, the video will also be large. In order to speed up processing the video, the video editor generally compresses it to shrink the size. Yet, that will weaken the color performance.

Why Images Lag behind Audios?

1. Low configured computer

If the computer is not equipped well, GPU cannot perform well. Then, the system is unable to update the images. Gradually, the images will lag behind the sounds. Please remember to troubleshoot the software at first.

Try to update the drivers of the graphics card and the sound card and notice whether they are compatible with the hardware. If the latest versions don’t work, try the earlier versions.

2. Video bugs

Video bugs generated from the operations can lead images and sounds to be out of synchronization. At this situation, you have to give up the videos or download it again.

3. Improper use of video editor

Different video software is designed with different functions and usages. When you find that images lag behind sounds, you can review your operations on the video editor.

4. Bugs on video editor

If there are bug in the video splitter, you should update to the latest version or use the full version. If the problem cannot be solved, you should change a better application.

5. Bugs on video player

Too many video players will disorder the encoder and the decoder in the operating system, which leads images and sounds are out of synchronization. It is suggested that you install two video players at most.
