Batch ffmpeg and compress the files

Question:

Tag: batch-file,ffmpeg

I am doing a bunch of conversions with ffmpeg, where I need to watermark the content. I am using a batch file to run the ffmpeg application, but I want to automate all of this.

for %%a in ("*.mp4*") do ffmpeg -i "%%a" -i logo.png -filter_complex overlay "newfiles\%%~na.mp4"
pause

Source video files:

video_a.mp4
video_b.mp4
video_c.mp4

Source image files:

logo_x.png
logo_y.png
logo_z.png
logo_u.png

For every logo PNG image, ffmpeg should be executed for all MP4 video files.
Output should be written to a new folder named output_folder_ + name of the logo image, for example output_folder_logo_x.

And as soon as converting an entire folder like the logo_x output videos finished, the produced files should be compressed into a RAR archive with using best compression into a dropbox folder like c:/users/admin/documents/dropbox.

This way I could automate all the conversion and upload process.

In the end I would have in my dropbox/megaSync folder:

output_folder_logo_x.rar
output_folder_logo_y.rar
output_folder_logo_z.rar
output_folder_logo_u.rar

UPDATED CODE:

@echo off
setlocal EnableDelayedExpansion
for %%g in ("*.png*") do (
    echo %%~ng
    md folder_prefix_%%~ng
    for %%b in ("*.mp4*") do (
        %%~ng
        ffmpeg -i "%%b" -i %%g -filter_complex overlay "folder_prefix_%%~ng\%%~nb.mp4"
    )
)
pause

Answer:

Here is my suggestion for the batch code:

@echo off
setlocal EnableDelayedExpansion

set "FolderBaseName=output_folder"
set "BaseOutputFolder=%TEMP%\%FolderBaseName%"
set "DropBoxFolder=%USERPROFILE%\documents\dropbox\megaSync"
md "%DropBoxFolder%" 2>nul

for %%I in (logo_*.png) do (
    set "OutputFolder=%BaseOutputFolder%_%%~nI"
    md "!OutputFolder!" 2>nul
    for %%J in (*.mp4*) do (
        ffmpeg.exe -i "%%~fJ" -i "%%~fI" -filter_complex overlay "!OutputFolder!\%%~nJ.mp4"
    )
    %ProgramFiles%\WinRAR\Rar.exe a -cfg- -ep1 -inul -m5 "%DropBoxFolder%\%FolderBaseName%_%%~nI" "!OutputFolder!\*"
    rd /S /Q "!OutputFolder!"
)

endlocal

Open a command prompt window and run there:

This results in getting help displayed for the used commands.
