I used the code to convert 6 files at once to uncompressed .avi forfiles /p 264s /m *.264 /c "cmd /c ffmpeg -f h264 -i @file -vf scale=704*480 -y input_double_high.avi" it is working great, but re-saves the file with the same name on the previous file. I would like it to create a new files with difference names Thanks
