File Management
File browser
e-Babylab also features a file browser which allows users to create folders, upload, and manage their own experiment files, such as audio and visual stimuli, custom HTML and CSS files.
The supported file extensions for each of the allowed file types are as follows:
| Type | Formats |
|---|---|
| Audio | .mp3, .wav |
| Document | .css, .csv, .docx, .html, .pdf, .rtf, .tpl, .txt, .xlsx |
| Image | .gif, .jpeg, .jpg, .png |
| Video | .mp4, .ogg, .webm |
The recommended file sizes and formats for different types of stimuli are as follows:
| Media Type | Format | Resolution | Bitrate | File Size | Frame Rate |
|---|---|---|---|---|---|
| Video | MP4 with H.264 codec | 720p (1280x720) or lower | 2-4 Mbps | Aim for under 10 MB per minute | 30 fps or lower |
| Images | JPEG for photographs, PNG for graphics with transparency | 1280x720 pixels or lower | - | Under 200 KB per image | - |
| Audio | MP3 | - | 128-192 kbps | Aim for under 1 MB per minute | - |
Tip
- Use Handbrake to convert videos into different formats.
- Keep the file sizes as small as possible to ensure quick loading times (i.e. minimise lag in experiments).
