Extract every Nth line from a Text File using Command Line

In this video, I use the command line tool awk to extract every third line from a captions.sbv file. This should work on Mac, Linux and Windows Subsystem for Linux.

Move to Desktop Folder

cd ~/Desktop

View File (hit q to exit)

less captions.sbv

Extract Every Third Line from captions.sbv

awk 'NR % 3 == 2' captions.sbv

‘3’ is for every third line.
‘2’ means start with the 2nd line.

Save Every Third Line to a Text File

awk 'NR % 3 == 2' captions.sbv > captions.txt

Convert Linefeeds to Spaces

awk 'NR % 3 == 2' captions.sbv |tr '\n' ' ' > captions.txt

Change aspect ratio without re-encoding

ffmpeg -i capture.mov -aspect 4:3 -vcodec copy capture43.mp4

Change aspect ratio and re-encode

ffmpeg -i capture.mov -aspect 4:3 -r 30 -vf "scale=640:480" -vcodec h264_videotoolbox -b:v 700k -s 640x480 -pix_fmt yuv420p capture43encode.mp4

Change aspect ratio, pad and re-encode

ffmpeg -i capture.mov -r 30 -aspect 16:9 -vf "scale=640:480,pad=854:480:107:0" -vcodec h264_videotoolbox -b:v 700k -s 854:480 -pix_fmt yuv420p capture43pad.mp4

Note: When I imported these .mp4 videos into Final Cut Pro, the audio wasn’t working on them. Audio would play fine in QuickTime Player. To fix the problem, when encoding, I used the “mov” extension instead of “mp4”.
