• How to batch watermark a directory of videos with FFMPEG on a Mac [closed]

  13 août 2020, par analogvids

  I need to create a shell script that allows me to add a watermark (.PNG) to all of the video files in a given directory, and I need to do this on a Mac.

  


  I've successfully written and run a script to batch convert videos :

  


  for i in *.Avi; do ffmpeg -i "$i" -c:a aac -b:a 128k -c:v libx264  -preset veryslow "${i%}.mp4"; done)


  


  I have also successfully run a command to convert and watermark videos individually :

  


  ffmpeg -i test.MOV -i watermark.png -filter_complex "overlay=100:100" watermarked.mp4


  


  I combined them into the following script :

  


  # !/bin/bash

  


  for i in *.MOV ; do ffmpeg -i "$i" -i watermark.jpeg -filter_complex “overlay=0” ”$I%.mp4" ; done

  


  and this is the error message terminal spits out :
./batchwatermark10.sh : line 3 : unexpected EOF while looking for matching `"'
./batchwatermark10.sh : line 4 : syntax error : unexpected end of file

  


  This answer doesn't help, though I tried to adapt it for Mac. And this answer works, but it doesn't help me batch process a directory of video files.

  


  Any guidance would be greatly appreciated !

  


• Best approach to apply watermark on Image/Gif/Video with JavaScript/Node.js/AWS or Any API

  24 août 2020, par Arhan Shahid

  I am developing an application using Node.js/Express and Angular latest. The required use case is all media (includes most common image & video formats etc jpg, jpeg, png, gif, mp4) needs to be watermarked when uploading to the app (uploaded on AWS S3).

  


  I have seen examples with ffmpeg & cloudinary offering similar API. I am not sure about the efficiency and performance of both options.

https://cloudinary.com/cookbook/adding_video_watermark_as_an_overlay

  


  Above are a few links I have seen. I would like to know what would be the best approach to achieve this, either FFmpeg cloudinary or any other option.

  


• Add 2 watermark with scale2ref 40 percent width of video and timeout using FFmpeg

  3 septembre 2020, par Arun Maurya

  Add 2 watermark with scale2ref 40 percent width of video and timeout using FFmpeg

  


  timeout for the top right corner (first 8 sec) then the bottom right corner till the end time.

  


  ffmpeg -i 1597739850_368007908.mp4 -i artistsharleen.png -i artistsharleen.png -filter_complex "[1][0scale2ref=w='iw*40/100':h='ow/mdar'[wm][vid];[vid][wm]overlay=10:40:enable='between(t,0,8)'"[v1];[v1][2]scale2ref=w='iw*40/100':h='ow/mdar'[a][b];[b][a]overlay=main_w-overlay_w-10:main_h-overlay_h-10:enable='gt(t,8)[v2]" -map "[v2]" -map 0:a 17780739871599156232.mp4

  


  I'm able to place 2 watermarks with keyframe

  


  ffmpeg -i video.mp4 -i image2.png -i image2.png -filter_complex "[0][1]overlay=10:10:enable='between(t,0,8)'[v1];[v1][2]overlay=main_w-overlay_w-10:main_h-overlay_h-10:enable='gt(t,8)'[v2]" -map "[v2]" -map 0:a output.mp4

  


  but my images are not getting scaled as per video resolution, that's why i want to integrate scale2ref in this command

  


  Hope someone also faces this problem, can help me.
