Software recommendation: free tools to quickly handle video files

Generally we have two main basic needs when dealing with video files, one is to split a particularly large video into multiple files of the right size, and the other is just the opposite, to combine some too fragmented small videos into one whole video. Usually these need professional software to achieve, but if only used occasionally, it is perfectly possible to achieve with the help of some free tools.

Two steps to complete video merging

Due to the rapid popularity of smartphones, shooting videos has become easy, but when we shoot multiple different videos, it is more troublesome to share them one by one, so it is possible to merge them and then share them.

FFmpeg Joiner is a FFmpeg-based video merging tool that is very small in size because it has only one function. Once the software is running, click on the “Add Video Files” button in the tool interface, select the video files you want to merge in the pop-up dialog box, and add them to the list in the window. Of course, you can also select the corresponding video files in Explorer and add them by dragging and dropping them (Figure 1).



Click “Start Merge” button after adding, then a dialog box will pop up, set the file name of the merged video in “File Name”. Next, choose the type of video file in “Save as”, here we suggest you to choose a common format file like MP4 (Figure 2). After all the settings are done, click the Save button and wait for a moment to see the “Merge End” prompt box. Next, you can get the merged video files in the specified folder.


Video splitting is also easy

If you are not satisfied with the whole video you shot on your phone, you can split it and then merge the parts you are satisfied with. However, FFmpeg Joiner is a tool that can only do merging operations, so you need to use other tools to split it.

JoinerSplitter is also a video processing tool based on FFmpeg, through which you can not only complete video merging operations, but also, most importantly, video splitting operations. We first download and install the latest version of it (, and we need to remind you that this tool requires the support of the . First click the plus button in the toolbar on the right side of the window and select the video files you want to split in the pop-up dialog box. After adding the video files to the list, select one of them, and then you can preview the video file on the left side of the window.


Drag and drop the slider to the start point of the split position, and then click the “Selection Start” button in the toolbar below. Next, drag the slider to the end of the segment and click the “Selection end” button in the toolbar below. If you feel that the position obtained by dragging the mouse is not accurate, then you can directly enter the exact segmentation position in the “Start” and “End” input boxes. When you are done, click on the Scissors button in the toolbar and then click on the first input box below the list of windows on the right to set the directory where the split file will be saved. Then set the name of the saved file in the second input box, and finally click the “Export” button to export the split file (Figure 3).


Video compression for easy file transfer

Video files taken by cell phones or downloaded from the Internet are in various formats, and in order to manage them more conveniently and effectively, we need to convert them to compressed files. Usually, we choose “Format Factory” to convert multimedia files, but it can only convert file formats, not compress them at the same time.

So today we switch to the software “Komaru Toolbox” ( First click on the “Video” tab in the tool interface, click on the “Video” button in the pop-up window, and then select the video file to be converted and compressed in the pop-up dialog box (Figure 4). Next, the software will automatically set an output name at the bottom, and if you are not satisfied, you can click “Output” and then customize the output file name in the dialog box, while you can also choose other file formats in the “Save as” list.


Now choose the tool for the background conversion operation in the “x264 program” list, here we recommend you to choose the “x264-32-8bit.exe” version. If the user chooses the 10bit version, then the video converted and compressed by it will not be uploaded to the video site for playback. Next, select the “Copy Audio Stream” option in the “Audio Mode” list, this option is not to compress the audio stream information. Then check the CEF option below, and make sure the other options are default. Finally, click the “Compress” button to see a pop-up box, through which you can learn the status of the file conversion compression, compression will be completed through the sound to prompt the user (Figure 5).



★ If you select the “Compressed Audio” option in the “Audio Mode” list, then you also need to set the parameters of the corresponding conversion tool in the “Audio” tab (Figure 6).


★In the list below the “Video” tab, we can add multiple video files at once to be compressed and converted, but only if we set the parameters of the conversion tool accordingly first.
