[FFmpeg-user] Image sequence with part pixelated with a mask

[Ric Hunter]

Well that's a pretty good idea, it totally worked!!
Had to also double the "-safe 0" to make it work and I had inverted the
overlay at the end.
Thank you so much!
Final version of the script:

@echo off
setlocal enabledelayedexpansion

set input_folder=C:\ffmpegblurtst\basepics
set mask_folder=C:\ffmpegblurtst\msk1
set output_folder=C:\ffmpegblurtst\output
set filelist_path=%input_folder%\filelist.txt
set masklist_path=%mask_folder%\filelist.txt
set masksolo=%mask_folder%\realmask.png
set output_file=%output_folder%\output.mp4

ffmpeg -r 30 -safe 0 -f concat -i "%filelist_path%" -safe 0 -f concat -i
"%masklist_path%" -filter_complex
"[0]scale=16:12[scaled];[scaled]scale=640:480:flags=neighbor[pixelated];[1]scale=640:480[ms];[pixelated][ms]alphamerge[okalpha];[0][okalpha]overlay"
-c:v libx264 -pix_fmt yuv420p -b:v 10M "%output_file%"
