This article is aimed at users who need to convert a large number of MP4 videos to FLV format in batches. It introduces how to use the batch video processing function in office software to complete format conversion. The article combines before-and-after effect images and software operation interfaces to explain the complete steps, from entering the video tool, selecting "Convert Video to FLV," adding files or importing folders, to setting the save location and starting processing according to the workflow, helping users reduce repetitive operations and improve video file organization and delivery efficiency.
In daily office work, content archiving, website material organization, or legacy system compatibility handling, you often encounter this problem: there are many video files at hand, mostly in MP4 format, but the target platform, project specifications, or legacy players require the FLV format. Converting them one by one—opening conversion software, selecting files individually, and setting the output format for each—is not only time-consuming but also prone to missed or incorrect conversions, and the file names are not easy to check uniformly.
This article addresses the issue of "batch converting many video files to FLV format." With the help of the office software " HeSoft Doc Batch Tool " shown in the screenshots, you can add multiple video files to the task list at once and then convert them all into .flv files. Its role is not that of a single player, but a batch file processing tool designed for office scenarios. Its core value lies in reducing repetitive work, making file processing workflows for videos, documents, and images more suitable for batch execution.
Application Scenarios: When Is Batch Conversion to FLV Format Needed?
FLV is a common video container format still used on some web videos, legacy systems, material libraries, and specific playback environments. Although formats like MP4, MOV, and MKV are more common today, format conversion is necessary if a project requires FLV delivery or an older platform only recognizes FLV files.
Common scenarios include: first, a website or internal system requires video material to be uploaded in FLV format; second, a large number of MP4 files in a video material library need to be unified into a single format for easier archiving and retrieval; third, training courseware, demo videos, and short film materials need to be output as FLV per client requirements; fourth, a team receives video files from multiple sources and wants to standardize the extension and format to avoid compatibility issues during subsequent playback or import.
If there are only one or two files, manual conversion is acceptable; but when the number reaches dozens or hundreds, batch processing becomes very important. Using the batch conversion feature in office software combines the repetitive processes of "selecting the format, adding files, and clicking convert" into a single task, thus saving significant time.
Preview of Results: Before Processing, There Are Multiple MP4 Video Files
From the screenshot before processing, you can see that the folder contains multiple video files, with names including Video test 20.mp4, Video test 22.mp4, Video test 23.mp4, Video test 24.mp4, Video test 30.mp4, Video test 31.mp4, Video test 32.mp4, Video test 33.mp4, Video test 51.mp4, etc. The extension for these files is .mp4, indicating the current material is still in MP4 format.
For scenarios requiring uniform FLV delivery, the key issue before processing is that although the video content is ready, the format does not meet the target requirements. Converting them one by one involves not only repetitive steps but also checking each file name individually after conversion. The benefit of batch conversion is that it can keep the main body of the original file names unchanged, only uniformly converting the extension to .flv, making subsequent verification more straightforward.
Preview of Results: After Processing, FLV Video Files Are Generated Uniformly
The screenshot after processing shows that the same batch of videos has become FLV files, such as Video test 20.flv, Video test 22.flv, Video test 23.flv, Video test 24.flv, Video test 30.flv, Video test 31.flv, Video test 32.flv, Video test 33.flv, Video test 51.flv. The main body of the file names remains consistent with before processing, while the extension changed from .mp4 to .flv.
This kind of result is highly suitable for office file organization: there is a clear correspondence between the source material and the conversion results, allowing users to quickly confirm which videos have been converted based on file names. For batch delivery, a unified format also reduces anomalies during subsequent uploads, imports, or playback.
Operation Step 1: Enter Video Tools and Select "Convert Video to FLV"
After opening " HeSoft Doc Batch Tool ", you can see multiple office processing entries in the left-side tool category, such as File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, etc. Since the current task is video format conversion, you need to first click "Video Tools" on the left.
After entering Video Tools, the main area displays several video format conversion functions, including "Convert Video to MP4," "Convert Video to AVI," "Convert Video to MKV," "Convert Video to MOV," "Convert Video to FLV," "Convert Video to WMV," "Convert Video to WebM," and others. Based on the goal of this article, you need to select "Convert Video to FLV." This function card is highlighted with a red box in the screenshot, indicating this is the entry point for this batch conversion task.
The operational purpose of this step is clear: first inform the software of the type of task to be performed, which is to convert video files uniformly into FLV format. The expected result is entering the "Convert Video to FLV" task page, where you can then add the video files to be processed.
Operation Step 2: Add the Video Files to Be Converted or Import from a Folder
After entering the "Convert Video to FLV" page, you can see "Add Files" and "Import Files from Folder" options at the top of the interface. For a small number of files scattered in different locations, you can use "Add Files" to select them in batches; if all videos to be converted are in the same folder, using "Import Files from Folder" is more suitable, as it can import the videos from that folder into the task list at once.
The screenshot shows multiple records have been imported, with a table containing information like Sequence Number, Name, Path, Extension, Creation Time, Modification Time, and Actions. The Extension column shows mp4, indicating the current pending records are MP4 video files. Each row in the list corresponds to one video, and users can confirm whether the files were added correctly by their Name and Path.
The operational purpose of this step is to establish a batch processing list. The expected result is that all MP4 videos needing conversion appear in the list. If you find files that shouldn't be processed were added by mistake, you can delete the corresponding records using the operations column in the interface; if there are many files, you can also use the filtering and sorting features displayed on the interface to assist in viewing records, but whether to use them depends on actual needs.
Operation Step 3: Check the Task List and Proceed to the Next Step
Before batch conversion, it is recommended to check the task list. Focus on three pieces of information: whether the file names are complete, whether the paths are from the correct folder, and whether the extensions are for the original video format to be converted. The records shown in the screenshot are from the same test folder, and the names are consistent with the MP4 files in the pre-processing folder, indicating the import results meet expectations.
After confirming everything is correct, you can click the "Next" button at the bottom of the page. From the interface flow, you can see that you are currently at Step 1 "Select Records to Process," followed by Step 2 "Set Save Location" and Step 3 "Start Processing." Therefore, the purpose of clicking "Next" is to enter the save location setup phase and specify the output destination for the converted FLV files.
When setting the save location, it is recommended to choose an easily identifiable folder, such as creating a new folder named "FLV Output" or "Converted Files." This prevents the conversion results from mixing with the original MP4s and makes it easier to verify the number of files before and after processing later.
Operation Step 4: Set the Save Location and Start Batch Processing
According to the task flow, after completing the file selection, you need to set the save location and then enter the start processing phase. Although the screenshot does not show the specific button details of the subsequent pages, it can be reasonably inferred from the step indicator on the interface that the software will guide the user to complete the output location setting and execute the conversion task in the final step.
The operational purpose of this step is to determine where the converted FLV files will be saved and to initiate the batch conversion. The expected result is that the software processes the videos one by one according to the task list, converting the original MP4 files into FLV files. After completion, the user can open the save location to view the results; the file extensions should change from .mp4 to .flv, and the main body of the file names usually remains corresponding, making verification easy.
If there are many videos to be processed, it is recommended not to frequently move the original files or close the software during the conversion to avoid affecting the task reading. After the conversion is complete, you can archive, upload, or deliver according to the results folder.
Common Questions and Precautions
1. Will batch conversion change the original files? From the workflow shown in the screenshots, the software provides a "Set Save Location" step, and typically batch processing outputs the results to a specified location. For safety, it is recommended to save the converted FLV files to a separate folder and keep the original MP4 files as a backup.
2. Can you import an entire folder at once? Yes. The screenshots clearly show an "Import Files from Folder" button, which is suitable for situations where videos to be converted are stored centrally. This is more appropriate for batch office processing than selecting files one by one.
3. How to avoid missing files when there are many? It is recommended to first gather the videos to be converted into one folder, then use the folder import function. After importing, check the sequence numbers, names, and extensions in the table to confirm the quantity matches the number of videos in the original folder.
4. Why use a batch processing tool instead of manual conversion? Manual conversion is suitable for a small number of files, but problems like repetitive clicks, repeated settings, and easy omissions arise when the file count is high. The advantage of a batch processing tool is the ability to add multiple records at once and execute them uniformly, better meeting office efficiency requirements.
5. How to confirm the results are correct after conversion? You can compare the file names before and after processing. The file Video test 20.mp4 before processing becomes Video test 20.flv after, showing that the main body of the file name remains consistent and the extension has changed to FLV. For multi-file tasks, this correspondence is very convenient for verification.
Summary: Reduce Repetitive Operations with Batch Conversion
The key to converting many video files to FLV format lies not in whether a single file can be converted, but in how to efficiently and stably process a whole batch of files. Through the video tools of " HeSoft Doc Batch Tool ", you can enter the "Convert Video to FLV" function, add multiple videos at once or import files from a folder, and then follow the process to set a save location and start processing.
For users who often organize video materials, create courseware, handle website resources, or deliver files in a specified format to clients, batch conversion can significantly reduce repetitive work. It is recommended that you organize the source folder before conversion, check the task list during conversion, and uniformly verify the output files after conversion, making the MP4-to-FLV process clearer and more efficient.
