Add the scale filter:

ffmpeg -i thumb-168pa-usrao.jpg -i evercam-logo-white.png -filter_complex '[1]scale=iw/2:-1[wm];[0][wm]overlay=x=main_w-overlay_w-10:y=main_h-overlay_h-10' test.jpg

This will "reduce the size of watermark to half of its size".

  • Can you tell how we can move watermark little to left? – Junaid Farooq Dec 04 '19 at 21:57

  • Hey, i want to post another question if you can help? I have a video and I want to put the watermark on that as well but I know how to add it after creating mp4, is there anyway to just add watermark while making mp4 vidoe? – Junaid Farooq Dec 05 '19 at 16:20
