If you just want to overlay a video during a specific time (untested

ffmpeg -i main -i overlay -filter_complex \
"[1:v]setpts=PTS+60/TB[fg];[0:v][fg]overlay=enable='between(t,60,120)':eof_action=pass" \

or perhaps:

ffmpeg -i main -itsoffset 60 -i overlay -filter_complex \
"[0:v][1:v]overlay=enable='between(t,60,120)':eof_action=pass" \

You didn't provide any info about your inputs or your ffmpeg build, so
I assumed you had no audio.

As you are unsubscribed I CCd you, but check the archives for other
