File Management#

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.

Supported File Types#

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`

Recommended File Sizes and Formats#

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 (1280×720) 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	1280×720 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).
