FFMPEG Input and Output line for converting multiple videos

[Phillipj]

Hello all.

I need some help with my input and output commands in FFMPEG.

I need to convert multiple files at the same time. What do I need to do as input and output commands, if I want the same names on the files and the input name?

I using:

ffmpeg -i INPUT.MOV (-timecode 00:00:00) -c:v mpeg2video -dc 10 -sc_threshold 1000000000 -intra_vlc 1 -non_linear_quant 1 -qmin 1 -qmax 12 -bf 2 -g 12 -pix_fmt yuv422p -color_primaries bt709 -color_trc bt709 -colorspace bt709 -color_range mpeg -b 50M -minrate 50M -maxrate 50M -bufsize 17825792 -rc_init_occupancy 17825792 -flags +cgop+ilme+ildct -acodec pcm_s24le -ar 48000 OUTPUT.MXF

Perhaps can modify Baldricks bat file, shown here:

https://forum.videohelp.com/threads/356314-How-to-batch-convert-multiplex-any-files-with-ffmpeg

From:

for %%a in ("*.*") do ffmpeg -i "%%a" -c:v libx264 -preset slow -crf 20 -c:a libvo_aacenc -b:a 128k "newfiles\%%~na.mp4"

To:

for %%a in ("*.mov") do ffmpeg -i "%%a" your list of arguments "newfiles\%%~na.mxf"

Assumes that the argument list is valid and a new folder called 'newfiles' exists.

Hey Sambat.

I just gives me: -bash: syntax error near unexpected token `('

Sorry, not familiar with that term - is that Linux??

Try remove the ( ) from

(-timecode 00:00:00)

edit: Or are you using linux as sambat mentions?

[Phillipj]

No, it is on a mac.

Im not using the timecode at all, so thats not the case.

I ran the following (from your code) as a bat file from a command line inside the avi file source folder and the files converted ok.

for %%a in ("*.avi") do ffmpeg -i "%%a" -c:v mpeg2video -dc 10 -sc_threshold 1000000000 -intra_vlc 1 -non_linear_quant 1 -qmin 1 -qmax 12 -bf 2 -g 12 -pix_fmt yuv422p -color_primaries bt709 -color_trc bt709 -colorspace bt709 -color_range mpeg -b 50M -minrate 50M -maxrate 50M -bufsize 17825792 -rc_init_occupancy 17825792 -flags +cgop+ilme+ildct -acodec pcm_s24le -ar 48000 "newfiles\%%~na.mxf"

[Phillipj]

cool. thanks

I'm just not that good at this. But how did you do that? Did you make a .sh file and ran it in the terminal or ?

Phew!
Got me off that hook, thanks.

That seems to do the trick. Thanks
