How to cut up a video into uniform parts using a command line tool
I want to use a command line tool to cut up a video according to a specific interval, say 1 second. If I have a 60 second video, I expect it to be split up into 60 uniform parts. My only other requirement is that there be no re-encoding.
I've read two threads on this topic (1, 2). The 1st thread suggested an untrusted tool that no longer seems to be maintained. The 2nd thread suggested avconv to manipulate large segments of video with manual names. As I'll be cutting up these videos into potentially hundreds of smaller parts, the approach is far too tedious. One user offered a Bash script, but admitted this might "produce many errors and empty files". I'll repost this script here for clarity and to encourage a better solution:
#!/bin/bash
SAVEIFS=$IFS
IFS=$(echo -en "nb")
FILES=$(ls *.mp4|sort)
let START=0
for FILE in $FILES
do
echo Processing $FILE
mkdir "${FILE}-chop"
for COUNT in {1..59}
do
exec avconv -i "${FILE}" -ss $START -t 60 -c:v copy -c:a copy "./${FILE}-chop/${COUNT} - ${FILE}"
let START=$START+60
done
done
IFS=$SAVEIFS
Is a Bash script like this really the right approach here? Or is there a simpler, more efficient, more reliable tool that I can use for this purpose?
