Is It Possible to Join Video without Re-encoding?

Many video processing tools can combine multiple videos into a single file. However, they often transcode/re-encode the video, making the process lengthy, CPU-intensive, and resulting in reduced output quality. So is it possible to join video without re-encoding? Short answer: Yes, but with conditions. You first need to ensure that the videos have the same format, encoder, resolution and frame rate, and you also need a video combiner that supports lossless video merging. Only then can you join video files without re-encoding. In the following, I will share a simple lossless video merger and guide you through the entire process of combining videos without re-encoding. Please read on.

Tips. Most video clips created by the same device will have the same parameters and are ready for video joining without transcoding.

How to Merge Videos without Re-encoding?

There are some video joiners available for Windows that can be used to merge videos without re-encoding. FFmpeg is one of them. However, its command line interface deters many beginners. So, here I would like to introduce a simpler program, WonderFox HD Video Converter Factory Pro. This is a versatile application designed to handle a variety of audio and video related issues. It has an advanced video merging tool. When you provide videos with the same resolution, format, codec and frame rate, it can quickly merge the videos into one without re-encoding. At the same time, it can merge videos without losing quality.

Using this tool is simple. Now, just free download free download the software and see how to merge video files without reencoding below.

Step 2. Organize Video into a Pack

Click the Merge button to open the Merge window. You will see all your videos displayed in the Video List section. Select the videos you want to merge (at least two) and click the middle Merge button to create a video pack below.

In the pack, you can drag the video to change the order and remove the unwanted file. You can also create multiple packs for different merging tasks as this program supports batch processing. When you are done with the pack, hit the bottom Merge button to add it to the task list.

Step 3. Select Output Format

On the right side of the main interface, click the format image to open the output format library. Go to the Video tab and pick one profile from below. You are recommended to use the same format as the original to avoid video transcoding.

Note. Normally, the program will smart-fit the same settings as the source. But double-check the parameters in the “Parameter settings” and make sure that the video encoder, audio encoder, framerate, resolution, and aspect ratio are set to the original value.
