• How to set file name after merging video files (batch script, FFMPEG)

  4 juin 2022, par Subhradip Sarkar

  I use this bat script for converting .mp4(x264) files to .mp4(x265)

  


  for %% in ("*.mp4") do ffmpeg -i "%%a" -c:v hevc "%dp0NewFolder\%%~na[HEVC].mp4"


  


  So I'm trying to make another bat script for merging video files(concat).

  


  for %%i in (*.mp4) do echo file '%%i'>> vlist.txt
ffmpeg -f concat -safe 0 -i vlist.txt -c copy %~dp0NewFolder\%%~na.mp4


  


  Files to merge would be like
Vid_1.mp4,
Vid_2.mp4,
Vid_#.mp4
...

  


  I want to keep the part before "_" in the new file name

  


  What should I use instead of %% na ? To make it just Vid.mp4

  


  Currently it creates % na.mp4

  


• How to split one overlay script to multiple part scripts ?

  4 mai 2024, par mikezang

  I can slide 30 images from left to center and countdown 10 seconds, then keep slide to left..., but run this script more than hours...

  ffmpeg -hide_banner ^

...
    -loop 1 -i "images\30.png" ^
    -filter_complex_script script.txt ^
    -t 300 -y videos/mergeYearsTest.mp4


  


  I think that I can split script to create 30 parts video then merge them to shorten time :

  v01.mp4 is no any problems.

  ffmpeg -hide_banner -i "v01.mp4" -loop 1 -i "images\02.png" ^
    -filter_complex_script script-02.txt -t 10 -y v02.mp4


  


  but this v02.mp4 is the same as v01.mp4 without slide next image, I also tried -loop 1 "v01.mp4", that will be error, what can I do to create v02.mp4 as the same affect with full script ?

  


  ====================================================

  


  I got what I wonder, script-02 should be as below :

  


  script-02.txt
[0:v]scale=864:504:force_original_aspect_ratio=decrease,pad=864:504 :-1 :-1,setsar=1[s0] ;

  [s0][s1]overlay=x='if(between(t,0,10),max(W-w*t,0),max(0-w*(t-10),0-W))',
drawtext=fontfile='/WINDOWS/Fonts/Arial.ttf':text='%{eif\:10-t\:d}':
box=1:boxborderw=10|10:fontsize=24:x=w-tw-10:y=10:boxcolor=orange@0.4:fontcolor=red:enable='between(t,0,10)';
