Common Mistakes to Avoid

1. Incorrect HandBrake Preset Selection

Reason: Choosing a preset that doesn't prioritize audio syncing can lead to out-of-sync audio.
Solution: Select a HandBrake preset specifically designed for video editing or choose a custom preset with audio syncing prioritized.

2. Ignoring the Source File's Audio/Video Characteristics

Reason: If the source video has inherent audio/video timing issues, HandBrake might not be able to fix them entirely.
Solution: Try a different source file if possible, or adjust HandBrake's audio and video filters for better compatibility.

3. Incorrect Source File Selection

Reason: Using the wrong video file (e.g., selecting a shorter clip instead of the full screen recording) results in synchronization problems.
Solution: Ensure you are using the correct, full-length screen recording file as the source for HandBrake.

FAQs

Are there any other tools besides Handbrake that can fix audio sync issues?
Yes, other video editing software can also adjust audio sync. However, Handbrake is free, widely available, and relatively user-friendly, making it a popular choice for this specific task.
