Add black or colored borders, increasing frame size.
AddBorders( clip clip, int left, int top, int right, int bottom [, int color ] )
- int left, top, right, bottom = (required)
- int color = (black)
- Border color; specified as an RGB value. See this page for more information on specifying colors.
- For YUV clips, colors are converted from full-range (0–255) to tv-range (16–235).
Examples and Notes
- Add letterbox (top and bottom) borders:
## add dark blue borders, using hex color notation AddBorders(0, 86, 0, 86, $00008B) ## same as above, using named preset color AddBorders(0, 86, 0, 86, color_darkblue)
- Be aware that many older lossy compression algorithms don't deal well with solid-color borders, unless the border happens to fall on a macroblock boundary (16 pixels for MPEG).
- Use AddBorders in combination with Crop to shift an image without changing the frame size:
# Shift an image 2 pixels to the right Crop(0, 0, Width-2, Height) AddBorders(2, 0, 0, 0)
- Note, shifting this way with YUV clips must be done in 2-pixel increments.
- You can shift in sub-pixel increments with Resize.
