Frequently Asked Questions (FAQ)

Installation and Licensing

Q: How do I get Video Magic?

A: Video Magic is a desktop application. You can:

1. Download the installer from the official website
2. Select the appropriate version for your operating system (Windows/macOS/Linux)
3. Complete installation following the setup wizard

Q: Do I need to purchase a license?

A: Video Magic offers:

• Free trial period (3 days)
• Subscription service (monthly/annual)
• One-time license purchase

For specific pricing and plans, please check the "Buy License" page within the app.

Q: Can the license be used on multiple computers?

A: Licenses are bound to machine ID. To use on multiple computers, you need to activate separately or purchase a multi-device license.

Q: What happens after the trial period ends?

A: After the trial period ends, the software cannot process videos, but you can still:

• View and manage added videos
• Adjust parameter settings
• Restore all functions immediately after purchasing a license

Video Processing

Q: What video formats does Video Magic support?

A: Supports most common formats, including:

• MP4 (recommended)
• MOV
• AVI
• MKV
• FLV
• WMV
• WebM

If a format cannot be processed, recommend converting to MP4 format first.

Q: How large video files can be processed?

A: Theoretically no file size limit, but practically limited by:

• Available disk space (need enough space to store output)
• System memory (large files require more memory)
• Processing time (large files take longer)

Recommended single file not exceeding 10GB.

Q: Will video quality degrade after processing?

A: Video Magic tries to maintain original video quality, but:

• Any re-encoding may have slight quality loss
• Using high-quality source videos minimizes loss
• Avoid repeatedly processing the same video multiple times

Q: How many videos can be processed simultaneously?

A: No quantity limit, but recommended:

• Decide batch size based on computer performance
• Average computer: 10-20 videos
• High-performance computer: 50+ videos
• Processing large amounts in batches is more stable

Q: What if processing speed is very slow?

A: Methods to improve processing speed:

1. Turn off unnecessary features and filters
2. Reduce number of videos processed simultaneously
3. Close other resource-intensive programs
4. Use SSD storage for source videos and output
5. Consider reducing video resolution

Q: Can I pause or cancel processing?

A:

• Cancel Processing: Close the application to stop
• Pause Feature: Not supported in current version, but planned for future release
• Completed videos will be retained, incomplete ones will be discarded

Feature Usage

Q: How do random parameters work?

A: When you set minimum and maximum values:

• During each video processing, the software randomly selects a value within the range
• Example: Volume set to 50%-70%, one video might use 63%, another 58%
• This makes each video in batch processing different

Q: Can I preview the final effect?

A: Yes, using the preview feature:

1. Select a video from the video list
2. Click the "Preview" button
3. View preview with all effects applied
4. If parameter adjustment needed, return to modify and preview again

Q: Why are subtitles not displaying or misaligned?

A: Common causes and solutions:

1. Subtitle file encoding issue: Ensure UTF-8 encoding is used
2. Timeline mismatch: Check if subtitle timeline matches video
3. Subtitle format issue: Ensure SRT or ASS format is used
4. Font size too small: Increase font size
5. Path issue: Avoid special characters in path

Q: Can watermarks be dynamic?

A: Yes, two methods:

1. Video Watermark: Use MP4/MOV video files as watermark
2. Scrolling Text: Text can scroll across screen

Q: Will background music loop?

A: Yes, background music automatically loops:

• If music is shorter than video, it repeats
• Automatically cuts off at video end
• Ensures music matches video length

Q: What if concatenated videos have different lengths?

A: Video Magic handles automatically:

• Shorter video loops to match longer video
• Final output length matches main video (source video)
• Concat video stops when main video ends

Q: How to create identical multiple copies?

A: To generate identical copies:

1. Don't set parameter ranges, use fixed values
2. Example: Set volume to 50%-50% (equivalent to fixed 50%)
3. Don't use features requiring random selection (like random video from folder)

Metadata and Privacy

Q: What is video metadata?

A: Metadata is additional information in video files, including:

• Title, author, copyright information
• Creation date and time
• Recording device information
• GPS location information (if available)
• Editing software information

Q: Why remove metadata?

A: Reasons to remove metadata:

• Privacy Protection: Prevent leaking location, device information
• Copyright Management: Remove original author information
• File Size: Slightly reduce file size
• Platform Requirements: Some platforms may have metadata requirements

Q: Does removing metadata affect video quality?

A: No. Metadata is just additional information, removing it doesn't affect:

• Video image quality
• Audio quality
• Playback compatibility

Technical Issues

Q: Why can't some videos be added?

A: Possible reasons:

1. Format not supported: Try converting to MP4 format
2. File corrupted: Test if it plays normally in other players
3. Special encoding: Some special encodings may not be supported
4. Permission issue: Ensure file is not locked by other programs

Q: What if output video won't play?

A: Troubleshooting steps:

1. Confirm processing is fully complete (check if progress is 100%)
2. Check if output file size is normal (should not be 0 bytes)
3. Try different players (VLC, PotPlayer, etc.)
4. Check if disk space is sufficient
5. Review error logs (if available)

Q: Why is output file larger than source file?

A: Possible reasons:

1. Added extra content (background music, watermarks, etc.)
2. Video concatenation increases output resolution
3. Encoding settings result in higher bitrate
4. This is usually normal and doesn't affect quality

Q: Can paths contain Chinese characters?

A: Recommendations:

• Source file paths can contain Chinese
• Output paths can contain Chinese
• But using English paths is safer to avoid potential issues
• Avoid special symbols (like ?, *, <, >, etc.)

Q: Can it be used on macOS/Linux?

A: Yes, Video Magic is cross-platform:

• Windows: Fully supported
• macOS: Fully supported
• Linux: Fully supported

Features are consistent across all platforms.

Output and Publishing

Q: Can output videos be directly published to social media?

A: Yes, output MP4 videos can be directly uploaded to:

• YouTube
• TikTok
• Instagram
• Facebook
• Twitter
• Other mainstream video platforms

Q: How to batch upload processed videos?

A: Video Magic focuses on video processing and doesn't include upload functionality. Recommendations:

1. Use each platform's batch upload tools
2. Use third-party social media management tools
3. Write automation scripts (if needed)

Q: What are different platforms' video requirements?

A: Common platform requirements:

• YouTube: Supports various formats and resolutions
• TikTok: Vertical video (9:16), max 10 minutes
• Instagram: Square (1:1) or vertical (4:5, 9:16)
• Twitter: Max 512MB, max 2:20 duration

Recommend preparing source videos in appropriate sizes for target platform.

Performance and Optimization

Q: Does Video Magic use GPU acceleration?

A: Current version mainly uses CPU processing. GPU acceleration feature planned for future versions.

Q: Can I use the computer for other tasks while processing videos?

A: Yes, but:

• Video processing consumes significant CPU resources
• Other programs may slow down
• Recommend lightweight tasks (like web browsing)
• Avoid running other large programs simultaneously

Q: How to estimate required disk space?

A: Rough estimate:

• Output file size usually similar to source file
• If generating N copies per source video, need about N times space
• Recommend reserving 2-3 times total source file size
