II. Complete Workflow from Creating/Opening a Project to Exporting

1. Launch the Software and Import Media Files

Location: Left side of the toolbar / File menu.

Specific Steps:

1. After launching the software, click the “Add File” button on the toolbar (the icon is usually a “+” or a folder), or use the shortcut Cmd + O.
2. In the file picker that appears, select one or more video or audio files and click “Open”.
3. The files will immediately appear in the File List Area.

2. Select Output Format and Preset

Location: Bottom output settings area.

Specific Steps:

1. Below or at the bottom of the file list area, find the “Output Format” dropdown menu.
2. Click the dropdown menu and select the target format (e.g., MP4, MOV, AVI, MKV, etc.) and device preset (e.g., “iPhone 15 Pro”, “iPad”, “YouTube 1080p”).
3. If you need to further adjust parameters (codec, resolution, bitrate, etc.), you can click the “Settings” or “Custom” button nearby for advanced configuration.

3. Video Editing and Enhancement (Optional but Essential)

Location: The feature tabs in the preview and editing area.

How to do it:

• Trim: Click the “Trim” tab, use the sliders or enter timecodes to set the “start time” and “end time” to cut a clip. You can preview in real time.
• Effects: Click the “Effects” tab to adjust brightness, contrast, and saturation, or apply artistic filters such as “Grayscale” and “Old Film.”
• Watermark: Click the “Watermark” tab to add a “text watermark” or “image watermark” and set its position, opacity, and size.
• Subtitles: Click the “Subtitles” tab to “add subtitle” files (SRT, ASS, etc.) and simultaneously adjust the font, color, and time offset.

4. Specify the Output Folder

Location: The output settings area at the bottom.

How to do it: Next to the “Output Format” settings, find “Save to” or a similar option, click the “Browse” button, and select the target folder on your computer.

5. Start Converting and Export the File

Location: The bottom-right corner of the interface.

How to do it:

1. After confirming all settings are correct, click the large “Convert” or “Convert All” button at the bottom.
2. The software will jump to the “Conversion Progress” interface, displaying the task queue, progress percentage, and estimated remaining time for each file.
3. After the conversion is complete, the software usually plays a notification sound, and you can view the generated files in “History” or go directly to the output folder.

III. Advanced Tips for Common Features

1. Batch Conversion and Merging: After importing multiple files, select “Merge into one file” in the output format section, and the software will concatenate all videos/audio in list order and output them as a single file.
2. Hardware Acceleration Optimization: In the “General” or “Advanced” tab of “Preferences” (Cmd + ,), enable the “Use hardware acceleration encoding” option (such as Intel QSV, Apple M-series chip optimization) to significantly improve conversion speed.
3. Saving Parameter Presets: In the “Custom” settings of “Output Format,” after adjusting all advanced parameters (codec, frame rate, sample rate, etc.), you can click “Save as Custom Preset” for easy reuse in the future.
4. Preview Screenshot Capture: While playing in the video preview window, click the “camera” screenshot button below to save the current frame as a JPEG or PNG image, which can be used to create video thumbnails.

IV. Common Problems and Solutions

1. Issue: When importing certain video files, the software shows “unsupported” or fails to load.
   Solution: This is usually caused by missing specific codecs. Try setting the output format to a universal format (such as MP4/H.264) within the software first, then use the software’s “video compression” or “format conversion” feature for indirect processing.
2. Issue: The converted video file size is too large.
   Solution: In the output format “settings,” lower the “bitrate” and “resolution.” Using “constant quality” (CRF) mode instead of “constant bitrate” (CBR) typically achieves a better balance between file size and image quality.
3. Issue: The conversion process unexpectedly stops or the software becomes unresponsive.
   Solution: First, check whether the source file is corrupted. Second, close other applications that are consuming large amounts of CPU/memory. Finally, in the software preferences, try disabling hardware acceleration and switching to pure software encoding for conversion to improve stability.
4. Issue: Added subtitles are out of sync with the video.
   Solution: In the “Subtitles” editing tab, use the “delay” or “advance” feature (unit: milliseconds) to fine-tune the overall subtitle timeline. It is recommended to test with a short clip first to confirm the sync effect before performing the full conversion.
