Frequently Asked Questions (FAQ)

Basic Usage

Q1. What is GoFlow Pro?

A1. GoFlow Pro is a video management app for Mac that automatically detects and organizes action camera footage from GoPro, DJI, Insta360, and other cameras. It lets you merge split clips and trim videos with professional precision.

Q2. What cameras are supported?

A2. GoFlow Pro supports:

– GoPro: All models (GH/GX file patterns)

– DJI: Action cameras and drones (DJI_ patterns)

– Insta360: 360 and action cameras (VID_ patterns)

– Other cameras: Grouped by time proximity (within 15 seconds)

Q3. What video formats are supported?

A3.

– Input: MP4, MOV, MKV

– Output: MP4 (Free), MP4/MOV/MKV (Pro)

Q4. How does session detection work?

A4. GoFlow Pro analyzes filenames and timestamps to automatically group related clips:

– GoPro files are grouped by chapter numbers (e.g., GH010123, GH020123)

– DJI files are grouped by sequence patterns

– Other files are grouped if recorded within 15 seconds of each other

Getting Started

Q5. How do I import videos?

A5. There are several ways:

  1. Drag and Drop: Drag a folder onto the app window

  2. Import Button: Click the folder icon and select a folder

  3. Menu: File → Import Folder (⌘O)

  4. Camera Detection: Connect your camera and import when prompted

Q6. How do I merge clips?

A6.

  1. Select the clips you want to merge in the library

  2. Review the selection in the detail panel

  3. Click “Merge Selected”

  4. Choose the output location and format

Q7. How do I trim a video?

A7.

  1. Switch to Editor mode using the toggle at the top

  2. Open a video file in the editor

  3. Set in/out points using the timeline

  4. Add cut points if needed (Pro)

  5. Click Export to save the trimmed video

Q8. Where are merged videos saved?

A8. You choose the save location each time, or set a default export folder in Settings. Merged videos are saved to your specified location with a suggested filename based on the source clips.

Session Detection

Q9. Why are some clips in separate sessions?

A9. This can happen if:

– The clips were recorded with more than 15 seconds between them

– The camera was turned off and on between recordings

– The files come from different cameras

You can still select and merge clips from different sessions manually.

Q10. Can I customize session grouping?

A10. Currently, GoFlow Pro uses automatic detection based on camera patterns and time proximity. Manual session grouping is planned for a future update.

Q11. Why doesn’t GoFlow Pro recognize my camera files?

A11. If your camera uses a unique naming convention, files will be grouped by time proximity instead. Ensure your files have accurate creation timestamps for best results.

Camera Import

Q12. How does camera detection work?

A12. When enabled in Settings, GoFlow Pro monitors for SD cards from supported cameras. When detected, you’ll see a prompt to import the videos.

Q13. Can I auto-eject after import?

A13. Yes! When importing from a camera, you can choose “Import & Eject” to automatically eject the SD card after the import completes.

Q14. What if camera detection doesn’t work?

A14. Try these steps:

  1. Ensure “Detect camera connection” is enabled in Settings

  2. Make sure the SD card mounts properly in Finder

  3. Import manually using the Import Folder option

Troubleshooting

Q20. Merge failed – what should I do?

A20. Common causes and solutions:

– Incompatible codecs: Try merging fewer clips or use clips from the same recording session

– Insufficient disk space: Free up space and try again

– Corrupted file: Try excluding the problematic clip

Q21. Why is merging slow?

A21. GoFlow Pro uses stream copy (no re-encoding) for fast merging. If merging seems slow:

– Check available disk space

– Close other intensive applications

– Ensure the source and destination are on fast storage

Q22. The app crashes when importing large folders

A22. For very large folders (1000+ files):

– Import in smaller batches

– Ensure sufficient RAM is available

– Update to the latest version of GoFlow Pro

Q23. Video quality is different after merging

A23. GoFlow Pro uses stream copy, which preserves original quality. If quality differs:

– Ensure source clips have the same codec and resolution

– Check if the player supports the output format

– Try a different output format (Pro)

Q24. Audio is out of sync after merging

A24. This can happen with variable frame rate videos. Try:

– Using clips from the same continuous recording

– Checking if the original clips have sync issues

Technical

Q25. System requirements?

A25.

– macOS 14.0 (Sonoma) or later

– Apple Silicon or Intel Mac

– Sufficient storage for videos

Q26. How does stream copy work?

A26. Stream copy directly copies the video and audio streams without re-encoding. This means:

– Fast processing: No time-consuming encoding

– No quality loss: Original quality is preserved

– Same codec required: Source clips should have compatible formats

Q27. Can I use GoFlow Pro offline?

A27. Yes! GoFlow Pro works completely offline. Internet is only needed for the initial purchase and restore purchases.

Q28. Does GoFlow Pro upload my videos?

A28. No. All processing happens locally on your Mac. Your videos are never uploaded to any server.

Q29. What is FFmpeg?

A29. FFmpeg is an open-source multimedia framework used for video processing. GoFlow Pro includes FFmpeg to handle video merging and trimming. It runs locally and doesn’t transmit any data.
