ffmpeg: encoding in sequence all files to get one output

[marcorocchini]

Hi

for kindess, I have some .mxf of my cats :

C0001.mxf
C0002.mxf
C0003.mxf
C0004.mxf
C0005.mxf

etc...


for each .mxf file I need to apply this commandline of ffmpeg:

ffmpeg.exe -y -i input.mxf -filter_complex "[0:1] [0:2] amerge,volume=1" -c:v libx264 -profile:v main -level:v 4.1 -g 33 -bf 1 -crf 18 -flags +ildct+ilme -top 1 -x264opts tff=1:colorprim=bt709:transfer=bt709:colormatrix=bt709 -filter_complex crop=out_h=1080:y=0,scale=interl=1:in_range=tv:out_range=tv -pix_fmt yuv420p -c:a libvo_aacenc -b:a 256k -aspect 16:9 output.mp4

I wonder: can I encode all .mxf files in sequence so that I get one output.mp4 as the soum of all .mxf input files in continuous?


thanks

Did you mean appending them all end to end (one output for many inputs) ? or batch encoding one by one (one output per input) ?



If you mean 1 output joined, you join the mxf files together first with concatenate, then apply the current commandline to the one mxf

https://trac.ffmpeg.org/wiki/Concatenate

ffmpeg -f concat -i mylist.txt -c copy output.mxf

Where "mylist.txt" has:
file '/PATH/C0001.mxf'
file '/PATH/C0002.mxf'
file '/PATH/C0003.mxf'
.
.





If you meant one by one, so each mxf generates one mp4, you batch encode them

for %a in ("*.mxf") do ffmpeg.exe -y -i "%a" -filter_complex "[0:1] [0:2] amerge,volume=1" -c:v libx264 -profile:v main -level:v 4.1 -g 33 -bf 1 -crf 18 -flags +ildct+ilme -top 1 -x264opts tff=1:colorprim=bt709:transfer=bt709:colormatrix=bt709 -filter_complex crop=out_h=1080:y=0,scale=interl=1:in_range=tv:out_range=tv -pix_fmt yuv420p -c:a libvo_aacenc -b:a 256k -aspect 16:9 "%~na.mp4"
