Bigasoft Total Video Converter for Mac is a comprehensive multimedia file conversion and processing software. It supports a vast range of video and audio formats, and can perform basic video editing, compression, and device preset optimization. This article aims to provide a complete operation manual from interface familiarization to efficient output.

I. Detailed Explanation of the Core Interface and Workspace

After launching the software, the main interface is mainly divided into four logically clear areas, which together form an intuitive workflow.

• Top Menu Bar and Toolbar: Contains all advanced commands such as file operations, editing, and preference settings. The toolbar provides shortcut buttons for the most commonly used functions such as “Add File,” “Capture,” “Trim,” “Effects,” and “Snapshot.”
• Left Preset List Area: This is the core function area of the software. All conversion presets are arranged by category:
  • Device Presets: Categorized by brand (Apple iPhone/iPad, Android, Sony PSP, etc.) and model, with one-click optimization of output parameters.
  • Format Presets: Categorized by video (MP4, AVI, MOV, MKV, etc.), audio (MP3, AAC, FLAC, etc.), and web formats (WebM, FLV).
  • Quick Settings: Usually includes general optimization options such as “HD Video” and “Small File Size”.
• Middle File List and Preview Area:
  • The upper section is the list of added media files, displaying information such as file name, duration, and output preset.
  • The lower section is the built-in video player, used to preview the source file or the edited result, and is equipped with a playback control bar and timeline.
• Bottom Output Settings and Action Area: Here you can set the output folder path, and the most important “Convert” button is also located here. The conversion progress bar and task information are also displayed in this area.

II. Complete Workflow: From Import to Export

The following is the entire process for completing a standard video conversion task.

1. Create/Open a Project and Add Media Files

Step 1: Add source files. Click the “Add File” button on the far left of the toolbar (the icon is “+”), or use the shortcut Command + O to select one or more video/audio files from Finder. You can also drag and drop files directly into the file list area in the middle of the software.

Step 2: File management. In the file list, you can:

• After selecting a file, press the Delete key to remove it from the list.
• Use the “Sort” button in the upper right corner to adjust the file order, which will affect the order of batch output.

2. Select Output Format and Presets

Step 3: Select the target format. In the preset list area on the left, browse and click to select the desired output preset. For example, to convert to the universal MP4 format, expand the “Video” category and select “MP4 – MPEG-4 Video (*.mp4)”. To optimize for iPhone, expand “Apple Devices” and select the specific model.

3. Custom Settings and Editing (Optional)

Select a file in the file list area, and the editing buttons on the toolbar will become available.

• Trim (Cut): Click the “Trim” button, then drag the sliders at both ends of the timeline in the pop-up window or enter precise times to trim the video clip. Click “OK” to save the settings.
• Crop: Click the “Crop” button, then drag the crop box in the preview window or set the aspect ratio to remove black bars or focus on a specific area.
• Effects: Click the “Effects” button to adjust brightness, contrast, and saturation, and add a watermark (text or image) to the video.
• Advanced Settings: Click the “Advanced Settings” button below the file list or on the right side of the toolbar (or use the shortcut Command + I) to fine-tune parameters such as the video codec, resolution, bitrate, frame rate, as well as audio channels, sample rate, and more.

4. Set the Output Path and Start Conversion

Step 4: Specify the output location. In the “Output” section at the bottom, click the “Browse” button to select the folder where the converted files will be saved.

Step 5: Execute the conversion. Once you have confirmed all settings are correct, click the large “Convert” button at the bottom (or use the shortcut Command + R). The software will process all files in the list sequentially and display a real-time progress bar and estimated time remaining.

5. Completion and Export

When the conversion is complete, you will hear a notification sound and see a pop-up notification. The files have been saved to your specified output folder. You can see the “Completed” status in the “Status” column of the file list, or simply click the “Open Output Folder” button to quickly access the results.

III. Advanced Tips for Common Features

• Batch Convert to Different Formats: In the file list, you can assign a different output preset to each file individually. First select File A and choose Preset 1, then select File B and choose Preset 2, and finally click “Convert” to output multiple formats in one go.
• Merge Files: Hold down the Command key to select multiple files at once, right-click and choose “Merge into One File.” The software will concatenate them into a single file in list order, then apply the output preset.
• High-Quality Screenshots: Use the “Screenshot” button (camera icon) at the bottom of the preview window to capture the current frame and save it as a lossless PNG or BMP image—more precise than system screenshots.
• Preserve Source Folder Structure: In “Preferences” (Command + ,), you can set the output to retain the source files’ relative directory structure, making it easy to manage large batches and multi-level folder conversion tasks.

IV. Common Issues and Solutions

• Issue 1: Slow conversion speed.
  • Solution: Check whether “High-Quality Encoding” is enabled in “Advanced Settings” (this reduces speed). While meeting your requirements, appropriately lower the output resolution or bitrate, or use a more efficient codec (such as H.264). Ensure your Mac has sufficient available memory.
• Issue 2: Converted files are too large or too small.
  • Solution: Precisely control the video bitrate and audio bitrate via “Advanced Settings.” Bitrate is the key factor affecting file size. Using “Constant Bitrate (CBR)” makes file size easier to predict, while “Variable Bitrate (VBR)” delivers better quality at the same file size.
• Issue 3: “Unsupported” prompt or failure to import when adding files.
  • Solution: Confirm that the file is not corrupted. Some special encodings or container formats may not be within the software’s supported range. Try using another tool to convert the file into a universal intermediate format (such as MOV/MP4), then process it with this software.
• Issue 4: The converted video cannot be played on the device or is out of sync.
  • Solution: Prefer the built-in “Device” presets in the software, as these presets have been specifically optimized. If you configure parameters manually, make sure they comply with the device specifications (such as resolution limits and encoding formats). Audio-video desynchronization may be caused by a problem with the source file, or by insufficient resources during the conversion process. Try restarting the software and then converting the file separately.
