If there are a large number of MP4 videos in a folder that need to be uniformly converted to MKV format, you can use the video conversion feature of HeSoft Doc Batch Tool to accomplish this. This article focuses on the practical office need of "batch converting multiple videos to MKV," demonstrating the file changes before and after processing, and explains with screenshots how to select "Convert Videos to MKV," import files, verify the list, proceed to the save location settings, and start the processing, helping users efficiently standardize their video formats.
Many people encounter a practical problem when organizing video materials: a folder accumulates a large number of MP4 videos with different names and content from various sources, but they eventually need to be uniformly converted to MKV format. For example, archiving company training videos, handing over project materials, organizing course files, and retaining meeting recordings often require consistent file formats. If you rely on manual conversion one by one, each video requires repeated selection, export, and confirmation, which becomes very inefficient when dealing with a large quantity.
This article will introduce a processing method suitable for office scenarios: using HeSoft Doc Batch Tool to batch convert multiple MP4 videos to MKV format. This software is designed for batch processing of office files, and its core value lies in consolidating file operations that originally required repeated execution into a single process. The following will combine before-and-after effect images and step-by-step screenshots to fully explain the workflow from selecting the function to importing files, and finally to generating the MKV result files.
Applicable Scenario: Multiple MP4 Videos Need to Be Unified into MKV
Batch video to MKV conversion is not only suitable for professional video editors. In fact, it is also very common in ordinary office environments. For example, administrative staff need to organize meeting videos, training managers need to archive course recordings, operations personnel need to unify media library formats, teachers need to organize teaching videos, and project staff need to save delivery materials according to specifications. The commonality of these scenarios is: a large number of videos, the need for a unified format, and high costs associated with repetitive manual processing.
In this example, the source files are a group of MP4 videos, including files named Video test 23.mp4, Video test 24.mp4, Video test 26.mp4, Video test 27.mp4, Video test 29.mp4, and Video test 30.mp4. They are located in the same test folder, making them suitable for one-time import into the software for batch conversion. After the conversion is complete, the file suffixes become .mkv, forming the corresponding MKV video files.
This type of requirement is particularly well-suited for batch processing tools. This is because the user only needs to uniformly select files and set the output location before starting, and then the software can process them according to the list, eliminating the need to repeatedly open individual files to perform the conversion.
Effect Preview: The Folder Contains MP4 Format Videos Before Conversion
Before processing, the video file suffixes in the folder are all .mp4. The screenshot shows multiple video thumbnails, some in landscape orientation and others in portrait orientation, indicating that the video content and dimensions may not be completely consistent. However, for a format conversion task, the key point is that these files currently all belong to the MP4 format and need to be uniformly output as MKV.
Before officially starting the conversion, it is recommended to first confirm the scope of the source files. For example, check whether only the videos in the current folder should be converted, whether there are files that do not need processing, and whether there are videos with similar names but different content. Although batch operations are efficient, the more thorough the preliminary confirmation, the more stable the subsequent results will be.
Effect Preview: Corresponding MKV Files Obtained After Conversion
After processing is complete, corresponding MKV format files appear in the folder. Comparing before and after processing, it can be seen that the main part of the file names remains consistent. For example, Video test 23 corresponds to Video test 23.mkv, and Video test 24 corresponds to Video test 24.mkv. For data archiving and batch verification, this result is very intuitive.
From the effect images, it is clear that this operation solves the problem of "batch MP4 to MKV conversion," rather than simply modifying file name suffixes. The user's ultimate goal is to obtain video files that can be used in the MKV format while maintaining the correspondence between the batch files.
Operation Steps: From Function Selection to Batch Conversion Completion
Step One: Open HeSoft Doc Batch Tool and enter the Video Tools category
After launching the software, there are multiple tool categories on the left, including File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, etc. Since the processing targets this time are video files, you need to enter "Video Tools".
After entering Video Tools, the main area will display multiple video-related functions. The screenshot shows function cards like "Video to MP4", "Video to AVI", "Video to MKV", "Video to MOV", and "Video to FLV". Select "Video to MKV" according to the target format.
The expected result of this step is to open the video processing page dedicated to batch MKV conversion. Choosing the correct function is very important; if the target is MKV, do not mistakenly select other format conversion entries like MP4, AVI, or MOV.
Step Two: Add Files After Entering the "Video to MKV" Page
After entering the function page, the interface title displays "Video to MKV". The top of the page provides "Add File" and "Import Files from Folder" buttons. For a small number of files, click "Add File" to select them one by one; for multiple videos in one folder, "Import Files from Folder" is more suitable for batch processing.
In the screenshot, the red arrow points to "Add File", indicating that videos to be processed can be selected from here. The example shows 6 records have been added, indicating that multiple videos can be added to the task list simultaneously. The software lists information such as Name, Path, Extension, Creation Time, and Modification Time in a table, making it convenient for users to check.
The purpose of this step is to add the MP4 videos to be converted into the software's processing queue. The expected result is that all video records needing conversion appear in the table, and the total count summarized at the bottom matches the imported number. For example, the screenshot shows "Record count: 6", indicating there are currently 6 files waiting for conversion.
Step Three: Confirm Files Are Imported Correctly Based on List Information
After adding files, it is not recommended to immediately proceed to the next step; instead, first check the task list. The "Name" in the list helps you confirm whether the file is the target video, "Path" confirms which folder the file comes from, and "Extension" confirms the current source file format. From the screenshot, the extension column is mp4, matching the task requirement of "MP4 to MKV conversion".
If there are many file names, you can use the "Filter" and "Sort" options on the interface for viewing. Although the screenshot does not show specific filter criteria, the buttons indicate that auxiliary management of the list is possible. For batch conversion of a large number of videos, organizing the task list first can prevent incorrect files from entering the processing flow.
If a specific row does not need processing, you can remove the record using the operation area on the right side of that row. This allows you to exclude irrelevant files before the official conversion, resulting in a cleaner final output.
Step Four: Click "Next" to Enter the Save Location Settings
After confirming the task list is correct, click the "Next" button at the bottom of the page. From the process hint in the screenshot, the software processing flow is divided into three stages: Step one is "Select records that need processing", step two is "Set save location", and step three is "Start processing". Once the current list is confirmed, you should proceed to the save location settings.
The save location setting will affect the finding and management of result files. For batch video to MKV conversion, it is recommended not to choose the desktop or a temporary directory casually, but to create a clear output folder. For example, you can create an "MKV Format Results" folder next to the original video directory. The advantage of this is that source files and conversion results are stored separately, making them easier to compare, back up, and deliver.
If the source video files are large, the resulting files after conversion may also take up significant space. Therefore, before setting the save location, ensure the target disk has sufficient capacity. Especially when processing dozens of videos at once, insufficient disk space might cause some files to fail during generation.
Step Five: Start Processing and Wait for the Software to Generate MKV Files in Batch
After completing the save location settings, enter the "Start processing" stage. The software will execute the video format conversion according to the records in the task list, converting MP4 videos to MKV format in batch. At this point, the user just needs to wait for the processing to complete, without having to repeatedly execute the conversion operation for each video as in traditional methods.
During processing, it is recommended to keep the source file locations unchanged, not move or rename the video files being processed, and not close the software window. This reduces the chance of task interruption. If the number of videos is large or the file sizes are large, the conversion time will increase accordingly, which is a normal phenomenon.
Step Six: Check the Output Results After the Conversion is Complete
After the conversion is complete, open the save location to view the result files. Ideally, the output file names correspond one-to-one with the source files, and the extensions are uniformly changed to .mkv. You can refer to the after-processing effect image to confirm whether files like Video test 23.mkv, Video test 24.mkv, and Video test 26.mkv have been generated.
When checking the results, it is recommended to focus on three aspects: first, check if the number of files matches the task list; second, check if all extensions are mkv; third, spot-check whether the videos can play normally. For important materials, spot-checking playback is especially necessary, because just seeing that a file exists does not mean the content meets expectations.
Frequently Asked Questions and Precautions
1. Is this method suitable for converting only one video?
Yes, it can be used, but it is more suitable for batch processing multiple videos. If you only have one video, you can also import and convert it via "Add File"; if you have a large number of videos, the efficiency advantage of batch processing will be more obvious.
2. What is the difference between Add File and Import Files from Folder?
"Add File" is more suitable for selecting a few specific videos; "Import Files from Folder" is more suitable for centrally adding videos from a specific directory to the task list. For uniformly converting multiple MP4 videos in a folder to MKV, the latter usually saves more time.
3. How to avoid losing files after the conversion is complete?
The key is to set the save location clearly. It is recommended to create a dedicated output directory before processing and use an easily identifiable folder name. After the conversion is complete, go directly to that directory to check the results, preventing result files from being scattered in different locations.
4. Why is backup recommended before batch processing?
Video files are often large in size and costly to reacquire. Although batch conversion typically generates results in a new format, for safety reasons, it is best to back up the source files of important videos first. This way, even if the output results do not meet expectations, you can reconvert them.
5. Can other video formats also be converted to MKV?
From the function name, "Video to MKV" is used to convert video files to MKV format. The screenshot example imports MP4 files, so this article focuses on explaining batch MP4 to MKV conversion. If you have files in other video formats, you can import and test them based on the software's support during actual operation, and the software's recognition and processing results shall prevail.
Summary: Unify Video Formats and Improve Office Efficiency with Batch Processing
When many MP4 videos in a folder need to be uniformly converted to MKV format, processing them one by one wastes a lot of time. Using HeSoft Doc Batch Tool , you can enter "Video to MKV" through "Video Tools", then use "Add File" or "Import Files from Folder" to add multiple videos to the task list, set the save location after confirming the records, and finally start the batch conversion.
The value of this method lies in centralizing repetitive labor: one-time import, one-time setting, and batch output. For office scenarios such as video material organization, course archiving, meeting recording management, and project file delivery, it can significantly reduce manual operations and improve the accuracy of file processing. It is recommended that you first organize the source video folder, then follow the steps in this article to execute the conversion, and check the MKV file count and playback status after completion.
