Transparent background MOV to Apng animation output size difference

[stealthrt]

Hey all I have been trying to get the settings correct with this cli:

ffmpeg -i "V:\weather animations\light snow.mov" 
       -framerate 15 
       -plays 0 
       -s 480x480 
       -vf setpts=PTS-STARTPTS 
       -f apng "V:\weather animations\light snow.apng"

Though the above command line does produce an animated apng file Its almost half the size as the original (its 750x750).



The original size of the mov:



When I use an online converter like ezgif it has the size of 8mb for the same thing above running the local ffmpeg command line.



So what setting am I forgetting?

Can you clarify what are you asking about the "output size" . What did you expect ?

What format is the original mov ? What codec ? What framerate? You can use mediainfo or ffprobe

GIF uses a limited pallette, 256 colors, so it's not comparable in terms of quality or filesize
