• ffmpeg cut off first 10 seconds of video then add intro 15 seconds in

  30 juillet 2020, par Peterwall

  New to FFmpeg but this should be possible. Basically what I want is to have a script that is able to in bulk cut out the first 10 seconds of every video then add my intro.mp4 15 seconds into the video. The same intro.mp4 file should also be added at the end of the video.

  


  At the moment I'm using the code below that I found somewhere... It's a good foundation but I need to add the intro.mp4 15 seconds into the video and I need to cut off the first 10 seconds of the video. Oh, and I'd also like to add a watermark (overlay.png) in the corner of the video. (Something like this : -i "%%a" -i overlay.png -filter_complex "overlay = 20:20").

  


  I'd really appreciate any help as I'm very new to FFmpeg ! :-)

  


  SET RESOLUTION="1280:720"
SET INPUT_FOLDER="input"
SET INTRO="intro.mp4"
SET OUTPUT_FOLDER="output"

for %%a in ("%INPUT_FOLDER%\*.*") do ffmpeg -i %INTRO% -i "%%a" -filter_complex "[0:v]scale=%RESOLUTION%:force_original_aspect_ratio=1,p ad=%RESOLUTION%ow-iw)/2oh-ih)/2[v0]; [1:v]scale=%RESOLUTION%:force_original_aspect_ratio=1,p ad=%RESOLUTION%ow-iw)/2oh-ih)/2[v1]; [v0][0:a][v1][1:a]concat=n=2:v=1:a=1[v][a]" -map [v] -map [a] "%OUTPUT_FOLDER%\%%~na.mp4"


  


• Copying, Trimming and adding intro/outro to many videos at once

  12 avril 2020, par necakaranfil

  Is there a way to :

  



  

  1. Make n copies of a single video in a folder (not manually) ;

  


  2. Trim the beginning and the ending part of each randomly by a range of minutes:seconds:miliseconds ;

  


  3. Add a watermark of a certain duration at a minute:second ;

  


  4. Append an intro and an outro video to each ;

  


  5. Edit metadata of each using spyntax ;

  


  6. Rename each video using spyntax ;

  


  



  I've been doing this manually for awhile, and i'm sure there may be a better way. Any of the following would be very helpful, if all are not possible.

  



  Thank you for your time :)

  


• ffmpeg mass add intro to mp4 videos

  2 février 2016, par F3rnand

  I found this script from forums, and a user suggests to use this code to mass add my mp4 files with intro.

  for %a in ("*.mp4") do mencoder -ovc copy -oac copy c:\intro.mp4 "%a" -o "c:\temp\%%a"

  When i use this code on ff Prompt in my Windows Pc. It won’t do anything. I added my data to the location above.

  Can anybody explain or suggest how to fix this ?
  I also want to know how to mass add outro to all my mp4 files.

  Thanks

  As Requested by mulvya, this is same for all videos as it is generated from same software

  but it returns same error
