USAGE:
   ffwebp [global options]

TOPIC:
   Path patterns for input (-i) and output (-o)

INPUT PATTERNS:
   - Globs: *, ?, [..] (shell-expanded on Unix; expanded by ffwebp on Windows)
   - Numeric sequences: %d, %02d (start at --start-number, default 1)

OUTPUT PATTERNS:
   - %d sequences (same numbering as input/index)
   - Templates (GNU-parallel style):
       {}    full input path
       {.}   input path without last extension
       {/}   basename (file name)
       {/.}  basename without extension
       {//}  directory (no trailing slash)
       {#}   sequence number (uses --start-number)

EXAMPLES:
   ffwebp -i "*.png" -o "{/.}.webp"
   ffwebp -i "frames/%03d.png" -o "out/frame-{#}.png" --start-number 10
   ffwebp -i "images/**/*.jpg" -o "out/{//}/{/.}.avif"

NOTES:
   - Output codec is inferred from the final extension unless --codec is set.
   - With multiple inputs, output must be a pattern or directory.
