To achieve the best results when filming a Holopresenter video, follow these guidelines to ensure optimal video quality and compatibility with Fectar Studio.
Orientation
- Always film in portrait mode. This ensures that the subject fills most of the frame, maximizing visibility and engagement in augmented reality (AR) experiences
Video Specifications
When uploading a video for a Holopresenter, ensure it meets the following criteria:
- Supported File Types: MP4, MOV
- Maximum Resolution: 3840 × 2160 pixels (4K)
- Maximum File Size: 500 MB
- Recommended Target Bitrate: Adjust based on resolution to optimize playback performance.
| Type | Max. Resolution | Target Bitrate | Frames per Second |
| .MP4 | 3840 x 2160 px | 5-10 Mbps | Max. 60 fps |
| .MOV | 3840 x 2160 px | 5-10 Mbps | Max. 60 fps |
Compression Considerations
- All uploaded videos will be compressed automatically to ensure smooth playback across a range of devices, including lower-end mobile phones.
- Higher frame rates (e.g., 60 FPS) significantly increase file size, especially for 4K recordings. If you plan to use 60 FPS, consider recording in 1080p (1920 × 1080) instead.
Green Screen Filming & Cropping
- When filming against a green screen, make sure that the person is well-lit and positioned centrally in the frame.
- Avoid showing the edges of the green screen, as these may remain visible even after background removal.
- Cropping the video can help eliminate unwanted parts of the frame:
- On iPhones, cropping is a built-in feature in the Photos app.
- On Android devices, you may need a third-party app to crop the video before uploading.
By following these steps, you can create high-quality Holopresenter videos that integrate seamlessly into your VR & AR projects in Fectar Studio.
