Answer 1

ffmpeg -i video.mp4 -ignore_loop 0 -i logo.gif -filter_complex "[0:v][1:v]overlay=x=10:y=10:format=auto:enable='lte(t,5)':shortest=1[bg];[bg][1:v]overlay=x=main_w-overlay_w-10:y=main_h-overlay_h-20:format=auto:enable='gte(t,5)':shortest=1,drawtext=text='@user1872811':fontsize=16:fontcolor=white:x=10:y=40:enable='lte(t,5)',drawtext=text='@user1872811':fontsize=16:fontcolor=white:x=w-tw-10:y=h-th-10:enable='gte(t,5)',format=yuv420p[v]" -map "[v]" -c:v libx264 -crf 18 -map 0:a -c:a copy -movflags +faststart output.mp4

You will need to adjust x and y positions for overlay and drawtext depending on the GIF width x height.

Adapted from:

• Text on video ffmpeg
• provide time period in ffmpeg drawtext filter
• How to position drawtext text
• How to add watermark with ffmpeg?

Top-Left To Bottom-Right loop:

ffmpeg -i video.mp4 -i watermark.png -filter_complex \
 "[0:v][1:v]overlay=x='if(lt(mod(t,10),5),10,W-w-10)':y='if(lt(mod(t,10),5),10,H-h-10)'" \
 -codec:a copy out.mp4

Top-Right To Bottom-Left loop:

ffmpeg -i video.mp4 -i watermark.png -filter_complex \
 "[0:v][1:v]overlay=x='if(lt(mod(t,10),5),W-w-10,10)':y='if(lt(mod(t,10),5),10,H-h-10)'" \ 
 -codec:a copy out.mp4

Idea is very simple

• Take every 10sec duration, get remainder sec ie mod(t,10)
• if sec < 5, set top position else bottom position

Please note I have excluded text ie username.

ffmpeg -y -i out.mp4 -i 1080_Happy_Holidays_Red_Videvo.mov -i logo.png -filter_complex "[0]scale=iw/4:-1[pip];[1][pip]overlay=100:100[watermark];[watermark][2]overlay=main_w-overlay_w-10:main_h-overlay_h-10" output.mp4
