How do I put ffmpeg output clips in a different folder

[DeJay]

Now I can batch process clips, thanks again, it gives me one more problem, namely a muddled folder full of original and processed clips. Mkdir produces a new folder, but how do I get ffmpeg to place its output in there please?

Add the desired path 'in front of' the output filename i.e.: C:\mypath\clip.mkv (windows) or /whatever/path/clip.mkv (linux)

Side to babiulep answer it will be good to add two additional steps - detection if required folder / directory exist and if not exist then create desired folder

[_Al_]

creation of a new directory was used in that "scary" python script
bash script with simple relative directory path:

#!/bin/bash
DIR_NAME="new_709_files"
mkdir -p ${DIR_NAME} #create that directory on disk if it does not exist
for filename in *.mp4
do
  NAME=$(basename "${filename}" .mp4)
  OUTPUT_FILENAME="${DIR_NAME}/${NAME}.mp4"
  ffmpeg -y -i "${filename}" -c copy "${OUTPUT_FILENAME}" # example, it does nothing just copies mp4 to that new folder
done

sometimes it is better to use absolute path, to work with absolute paths, if working directory is not the same as script etc. (not your case perhaps), then to get absolute path for you ffmpeg cmd:

#!/bin/bash
DIR_NAME="new_709_files"
mkdir -p ${DIR_NAME} #create that directory on disk
ABSOLUTE_OUTPUT_DIR_NAME=$(cd ${DIR_NAME}; pwd)  #creates absolute path for that new directory
for filename in *.mp4
do
  NAME=$(basename "${filename}" .mp4)
  OUTPUT_FILENAME="${ABSOLUTE_OUTPUT_DIR_NAME}/${NAME}.mp4"
  ffmpeg -y -i "${filename}" -c copy "${OUTPUT_FILENAME}"
done

Thank you all. Once again, with a bit of patience and some tinkering, it works a treat.
