Resize overlay video

I am overlaying a video on top of an image.

Using this command:

ffmpeg -i image.png -i input.mp4 -filter_complex "[0:v][1:v] overlay=10:10:enable='between(t,0,38)'" -pix_fmt yuv420p -c:a copy output.mp4

I understand the overlay=10:10 is the positioning but I can't seem to work out how to resize the overlay video (input.mp4).

I think I need to use scale but not sure how to.

Any help on scaling the overlay video would be appreciated!

With filter_complex you can combine commands and make named outputs Try something like this:
ffmpeg -i image.png -i input.mp4 -filter_complex "[1:v]scale=320x240[scaled_v];[0:v][scaled_v] overlay=10:10:enable='between(t,0,38)'" -pix_fmt yuv420p -c:a copy output.mp4
Just change resolution to what you need instead of 320x240.

If you need image overlay on top of video, swap [1:v] and [0:v]
