In FFmpeg, the way to place your logo picture is to use the -filter_complex parameter and defining the position by setting the overlay coordinate. Below are examples showcasing Subscribe logo in different locations.

Simple example with specific location

Put subscribe.png 10 pixels from the top and 10 pixels from the left.

ffmpeg -y -i VIDEO.mp4 -i subscribe.png -filter_complex "overlay=10:10" OUT_1.mp4

Logo in the center

Put subscribe.png in the center.

ffmpeg -y -i VIDEO.mp4 -i subscribe.png \
    -filter_complex "overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2" \
        OUT_CENTER.mp4
    # main_h: The video height.
    # main_w: The video width.
    # overlay_h: The overlay(logo) height.
    # overlay_w: The overlay(logo) width.

Logo at top-left corner

Put subscribe.png at the top left corner.

ffmpeg -y -i VIDEO.mp4 -i subscribe.png \
    -filter_complex "overlay=x=main_w*0.01:y=main_h*0.01" \
        OUT_TOP_LEFT.mp4

Logo at top-right corner

Put subscribe.png at the top right corner.

ffmpeg -y -i VIDEO.mp4 -i subscribe.png \
    -filter_complex "overlay=x=main_w-overlay_w-(main_w*0.01):y=main_h*0.01" \
        OUT_TOP_RIGHT.mp4

Logo at bottom-left corner

Put subscribe.png at the bottom left corner.

ffmpeg -y -i VIDEO.mp4 -i subscribe.png \
    -filter_complex "overlay=x=main_w*0.01:y=main_h-overlay_h-(main_h*0.01)" \
        OUT_BOTTOM_LEFT.mp4

Logo at bottom-right corner

Put subscribe.png at the bottom right corner.

ffmpeg -y -i VIDEO.mp4 -i subscribe.png \
    -filter_complex "overlay=x=main_w-overlay_w-(main_w*0.01):y=main_h-overlay_h-(main_h*0.01)" \
