🐛Bug

I think we need to resize image to convert them to video? Otherwise, we get this errors

ffmpeg -framerate 1 -pattern_type glob -i 'Kvasir-SEG/images/ck*.jpg' -c:v libx264 out720x576.mp4

Press [q] to stop, [?] for help
[libx264 @ 0x5593e14e27c0] height not divisible by 2 (622x529)
Error initializing output stream 0:0 -- Error while opening encoder for output stream 
#0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
