Convert png into movie for youtube

Just small piece of code does the magic!

avconv -i rlds_bced_1960_1999_ipsl-cm5a-lr_rcp8p5_20%02d.png -r 5 -c:v libx264 -crf 1  -pix_fmt yuv420p img2.mov

• -i "rlds_bced_1960_1999_ipsl-cm5a-lr_rcp8p5_20%02d.png" uses these files as the input, %d is a placeholder for the number
• -r 5 the desired frame rate, 5 FPS in this case
• -c:v libx264 use the h264 codec x264
• -crf 20 the video quality, 20 is pretty high, the default is 23
• -pix_fmt yuv420p a compatible pixel format
