This article introduces how to use HeSoft Doc Batch Tool to batch convert multiple MP4 video files to MKV format at once. The article covers applicable scenarios, effects before and after processing, specific operation steps, and precautions, helping users who need to organize video materials, unify file formats, and reduce repetitive tasks quickly complete video format conversion. Through the batch processing capabilities of office software, users can add multiple videos to a list, set the save location according to the wizard, and start processing, avoiding the time waste caused by converting one by one.
In daily office work, course creation, short video material organization, project archiving, or material delivery, you often encounter the issue of inconsistent video file formats within a batch. For example, there might be many MP4 videos in the same folder, but for subsequent editing, archiving, playback, or platform uploading, you want them uniformly converted to MKV format. If you open a conversion tool, select files, and set the output format one by one, it is not only time-consuming but also easy to miss files or save them to the wrong location. This article addresses this problem: how to batch convert many video files to MKV format.
As seen in the screenshot, the tool used is HeSoft Doc Batch Tool . This is an office-oriented batch file processing software that, besides common document processing, also provides a video tools category, suitable for reducing repetitive work when handling large numbers of files. This article will combine screenshots of the operation interface to explain how to enter the "Convert Video to MKV" function, how to add multiple video files, and how to follow the software wizard to complete the batch conversion. In the example, the pre-processing video files are MP4, and after processing, they become uniformly MKV, with the main body of the filenames remaining consistent, facilitating archiving and searching.
Applicable Scenarios: When Do You Need to Batch Convert Videos to MKV?
MKV is a common video container format, often used for saving high-definition videos, multiple audio tracks, multiple subtitles, or video content intended for long-term archiving. For office users, the need to batch convert to MKV is usually not for a single file, but for an entire folder, a set of project materials, or a batch of videos to be delivered. The value of using batch processing software lies precisely in consolidating repetitive actions into a single task.
The following scenarios are well-suited for the method described in this article:
- Material Organization: Uniformly convert multiple MP4 videos exported from cameras, phones, download tools, or editing software to MKV for easier subsequent categorized storage.
- Project Archiving: After a project is completed, you need to save multiple video files in a unified format into the archive, reducing management costs caused by mixed formats.
- Playback Compatibility: Certain playback environments or media libraries are more accustomed to using the MKV format, and you want to organize existing MP4, MOV, etc. videos into a uniform format.
- Batch Delivery: Before delivering videos to clients, colleagues, or course platforms, you need to unify the extension and file format to avoid the recipient having to process them individually.
- Reducing Repetitive Work: When the number of videos is large, manual conversion can take up a lot of time. Using the batch processing capabilities of office software can significantly improve efficiency.
It should be noted that the screenshot examples in this article primarily show the process of converting MP4 to MKV. Since the function name in the software interface is "Convert Video to MKV", it is typically used in practice to batch output video files into MKV format. For the specific input formats supported, please refer to the types importable during the actual file selection in the software and the processing results.
Result Preview: Before Processing, Multiple MP4 Video Files
In the pre-processing folder, multiple video files can be seen. The filenames include Video test 23.mp4, Video test 24.mp4, Video test 26.mp4, Video test 27.mp4, Video test 29.mp4, Video test 30.mp4, etc., all with the .mp4 extension. Manual processing might be acceptable for a small number of files, but if the number grows to dozens or hundreds, converting them individually can easily waste time.
Below is a screenshot of the result before processing, where the files are still in MP4 format:
As can be seen from the pre-processing screenshot, these videos are distributed in the same folder, with similar filename main bodies differing only in numbering. In actual office work, such files often come from the same project or the same batch of materials. If the filename main body can be preserved after conversion, with only the format extension changed, a clear file correspondence can be maintained.
Result Preview: After Processing, Uniformly Becoming MKV Format
After the batch conversion is complete, the original batch of MP4 videos has been transformed into MKV format. The filename main bodies are still Video test 23, Video test 24, Video test 26, etc., only the extension has changed from .mp4 to .mkv. This maintains the original naming logic while achieving unified format.
Below is a screenshot of the result after processing:
Comparing before and after processing, the core result of batch conversion is very clear: multiple video files changed from MP4 to MKV. This method of batch format unification is suitable for office users who need to standardize file delivery, organize media libraries, or build material archives. Compared to manual individual conversion, batch processing can reduce the risk of omission and also decrease manual waiting and repetitive clicks.
Operation Steps: Using Office Software for Batch Conversion to MKV
Step 1: Enter Video Tools and Select the "Convert Video to MKV" Function
After opening HeSoft Doc Batch Tool , you can see various tool categories in the left navigation bar, such as Home, Task Flow, All Tools, File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, etc. What we need to do here is video format conversion, so we need to enter "Video Tools".
On the Video Tools page, the software lists various video processing capabilities in the form of function cards, such as Separating Picture and Sound from Video, Deleting Sound from Video, Deleting Image from Video, Adding Watermark to Video, Convert Video to MP4, Convert Video to AVI, Convert Video to MKV, Convert Video to MOV, Convert Video to FLV, etc. According to the goal of this article, you should select "Convert Video to MKV". In the screenshot, this card is highlighted, with a prompt saying "Batch convert video files to MKV format", indicating it is exactly the function to be used this time.
The operational purpose of this step is to make the software enter the correct batch processing module. The expected result is to open the task page for "Convert Video to MKV", after which you can add the video files that need processing. If there are many functions in the Video Tools, you can locate "Convert Video to MKV" directly based on the card title, or use the search tutorials or quick navigation area at the top of the interface to assist in finding it.
Step 2: Add the Video Files to Be Converted
After entering the "Convert Video to MKV" page, the current function name is displayed at the top of the interface. On the left there is a "Return to Main Panel" button, and on the right there are buttons like "Add File", "Import Files from Folder", "Clear", "More", etc. The main area of the page is divided into three phases according to the process: Select records to process, Set save location, and Start processing. The current screenshot shows it is at Step 1 "Select records to process".
If you need to process a few specific videos, you can click "Add File" and select the files to be converted from your computer. If you want to process a large number of videos within a folder, you can click "Import Files from Folder", which is more suitable for batch importing video materials from the same project or directory. In the screenshot, 6 records have been imported, and the list shows information such as sequence number, name, path, extension, creation time, modification time, and actions.
The operational purpose of this step is to add the videos to be converted into the task list. The expected result is that all pending videos appear in the file list, and the path and extension of each file are displayed. From the screenshot, it can be seen that the example files' extensions are all mp4, and the path is under the C:\Users\Administrator\Desktop\Test folder 1\ directory. The bottom of the list shows the record count is 6, indicating that 6 videos will be batch processed this time.
Step 3: Check the List, Confirm No Incorrect Selections or Omissions
After importing the files, it is recommended to check the list content first. Focus on three types of information: first, whether the name is the video to be converted this time; second, whether the path is from the correct folder; third, whether the extension matches expectations. For batch conversion tasks, confirming the list is more efficient than reworking after processing.
In the interface, there is an action area on the right side of each record, showing a delete icon. If a file does not need to be converted, it can be removed from the list. On the right, you can also see "Filter" and "Sort" buttons, which are helpful for viewing the list when there are many records. The screenshot does not show more in-depth filtering configurations, so this article will not speculate further; during actual use, you just need to ensure the final list retains only the files to be converted.
The operational purpose of this step is to reduce errors in the batch task. The expected result is that the number and content of files in the list match the plan. For example, the example shows a record count of 6, indicating that 6 MP4 files will participate in the subsequent conversion.
Step 4: Click "Next" to Enter Save Location Settings
After confirming the file list is correct, click the "Next" button at the bottom of the page. From the interface process bar, you can see that Step 2 is "Set save location". This means the software will guide the user through a wizard to further configure where the output files should be saved. The save location is a very important step in batch conversion because it determines whether the converted MKV files are managed as an overwrite, saved to a new directory, or saved to a specific location. Specific options are subject to the actual page display of the software.
The operational purpose of this step is to move from the file selection stage to the output settings stage. The expected result is entering the save location settings page, where users can choose a suitable location according to their organization habits. In an office scenario, it is recommended to save the converted MKV files to a separate output folder, making it easy to compare files before and after processing and facilitating subsequent archiving and delivery.
Step 5: Start Processing and Wait for Batch Conversion to Finish
After setting the save location, continue to Step 3 "Start processing". It can be seen from the process design that the software will execute the conversion task after completing file selection and saving location settings. At this point, the user only needs to confirm the task is correct, then start processing and wait for completion. Because this is batch conversion, the software will process multiple video files sequentially according to the list records, reducing the operations required for individual conversion by the user.
After processing, you can open the save location to view the results. In the example post-processing screenshot, files like Video test 23.mp4, Video test 24.mp4, Video test 26.mp4 have correspondingly generated MKV files such as Video test 23.mkv, Video test 24.mkv, Video test 26.mkv. When checking, you can focus on confirming whether the number of files, filenames, and extensions meet expectations.
Common Questions and Precautions
1. Do I need to back up the original files before batch conversion?
It is recommended to keep the original video files, especially for project materials, client data, or videos that cannot be re-obtained. Although the example in this article shows obtaining MKV files after conversion, to avoid misoperation or output settings not meeting expectations, it is best to keep the original directory before conversion, or save the output files to a new folder.
2. Why do I only see an extension change after processing?
The intuitive result of video format conversion is usually reflected in the extension change, for example, from .mp4 to .mkv. File icons or thumbnails might not update synchronously due to system settings, default player, or thumbnail cache, so when judging results, you should prioritize checking the file extension and file properties.
3. Will the filename change?
Looking at the example results, the main body of the filename remains consistent, only the extension becomes MKV, for example, Video test 23.mp4 becomes Video test 23.mkv after conversion. This is very helpful for batch archiving, as users can quickly establish a one-to-one correspondence before and after processing. Actual conversion results should still be based on the software output.
4. Can many videos be imported at once?
The interface provides two entry points: "Add File" and "Import Files from Folder". For a small number of files, using Add File is sufficient; for a large number of videos in the same directory, using Import Files from Folder saves more time. After importing, it is recommended to verify by checking the record count, name, and path.
5. What preparations can be made during the conversion process?
Before starting the batch conversion, it is recommended to close any players or editing software that are occupying these videos, and ensure there is enough space at the save location. Video files are usually large in size, and batch processing has certain requirements for disk space and read/write speed. After processing is complete, check the output files uniformly.
Summary: Using Batch Processing to Unify Video Formats and Reduce Repetitive Work
The key to batch converting video files to MKV is not whether a single file can be converted, but whether a large number of files can be processed in one go using the same workflow. Through the video tools of HeSoft Doc Batch Tool , you can first enter the "Convert Video to MKV" function, then add multiple videos to the list via "Add File" or "Import Files from Folder", check for errors, click "Next" to set the save location, and finally start processing.
For users who often need to organize video materials, archive project files, or unify delivery formats, this office-software-style batch processing workflow can significantly reduce repetitive clicks and lower the probability of missed or incorrect conversions. If you have a batch of MP4 videos that need to become MKV, it is recommended to first gather the original files into one folder, then follow the steps in this article to batch import and convert them. This makes the processing clearer and the results easier to verify.
