Animated Screens
Each screen can be animated using an optional animated GIF or Video Files by creating a file with the same name as the main screen image e.g. ready.gif | ready.mp4 for the ready.jpg screen.
If the GIF should play in a continuous loop the suffix _loop should be added to the filename e.g. ready_loop.gif.
By default the GIF or Video will be centered on the screen. The position can be specified by appending the following modifiers enclosed in curly brackets to the end of the filename:
| Modifier | Description |
| T | place the center of the GIF/Video at the top of the screen |
| B | place the center of the GIF/Video at the bottom of the screen |
| L | place the center of the GIF/Video at the left of the screen |
| R | place the center of the GIF/Video at the right of the screen |
| W | width of the GIF/Video |
| H | height of the GIF/Video |
Examples
Each modifier can be followed by a number followed by % (to specify the percentage offset of the screen size).
| Example | Description |
ready.gif |
place a GIF that plays once in the ready screen and place it in the center of the screen |
ready_loop.gif |
place a GIF that plays in a continuous loop in the ready screen and place it in the center of the screen |
ready_loop_{T0%}.gif |
place a GIF that plays in a continuous loop in the ready screen and place its center at the top of the screen (the top half will be off the screen), centered horizontally |
ready_loop_{T10%}.gif |
place a GIF that plays in a continuous loop in the ready screen and place its center 10% of the screen height from the top of the screen, centered horizontally |
ready_loop_{B10%R20%}.gif |
place a GIF that plays in a continuous loop in the ready screen and place its center 10% of the screen height from the bottom of the screen and 20% of the screen width from the right of the screen |
ready_loop_{T10%W10%}.gif |
place a GIF that plays in a continuous loop in the ready screen and place its center 10% of the screen height from the top of the screen, centered horizontally and resize to 10% of the screen width |
Videos with alpha channels allow the transparency of the video to be controlled on a frame by frame and pixel by pixel basis. This makes it possible to create a video which has some areas that are fully transparent and other areas with varying transparency from semi-transparent to fully opaque.
Videos with alpha channels used animate screens in Breeze Booth for iPad need to be saved as QuickTime files in HEVC format. The HEVC video format with alpha channels is relatively new and does not yet have widespread support. Many high end video editing tools can create videos with alpha channels in Apple ProRes 4444 format which can then be converted to HEVC format. This can be done using Apple's QuickTime Player that comes free with MacOS. QuickTime Player also has the ability to load a series of PNG images with alpha channels and then export them as an HEVC video.
