Hi Guys;
I'm new to ffmpeg and I'm trying to figure out what is wrong with the below
filter.  It keep erroring out with the following error:
Unable to find a suitable output format for '[rgb_in][alpha_in][rgb_in]'

ffpmpeg -i "D:\TEMP\Source Files\720E\MLB21_INT_PLAYER_720.mov" -i
"D:\TEMP\Source Files\Audio\file_example_WAV_1MG.wav" -vf scale=1920:1080
-filter_complex 'split [rgb_in][alpha_in][rgb_in] lutrgb=a=minval
[rgb_out][alpha_in] format=rgba, split [T1], fifo,
lutrgb=r=maxval:g=maxval:b=maxval, [T2] overlay [rgb_out][T1] fifo,
lutrgb=r=minval:g=minval:b=minval [T2][alpha_out]' -map '[rgb_out]'
"D:\TEMP\Source Files\Done\MLB21_INT_PLAYER_720_ProRes422-1080_ST_F.MOV"
-map '[alpha_out]' "D:\TEMP\Source
Files\Done\MLB21_INT_PLAYER_720_ProRes422-1080_ST_M.MOV" -acodec copy -map
0:0 -map 1:a:0 -y

Any ideas?
Thank you.
