# Convert MP4 animations to 60fps MP4 (via minterpolate) and optimized GIF.
|
|
#
|
|
# Usage:
|
|
# ./convert-formats.sh input.mp4 [gif_width]
|
|
#
|
|
# Produces next to the input:
|
|
# <name>-60fps.mp4 (1920x1080, 60fps, motion-interpolated)
|
|
# <name>.gif (scaled width, 15fps, palette-optimized)
|
|
#
|
|
# minterpolate flags:
|
|
# mi_mode=mci motion compensation interpolation
|
|
# mc_mode=aobmc adaptive overlapped block motion comp
|
|
# me_mode=bidir bidirectional motion estimation
|
|
# vsbmc=1 variable-size block motion comp
|
|
# GIF uses two-pass palette:
|
|
# pass 1: palettegen with stats_mode=diff (per-video optimal palette)
|
|
# pass 2: paletteuse with bayer dither + rectangle diff
|
|
# This keeps 30s/1080p animations GIF under ~4MB with good color fidelity.
