doralsoral:
I wrote this script for you.
save it as framefromtime.sh
go into a console
run 'chmod +x framefromtime.sh'
then run 'framefromtime.sh <your video standard> <minutes> <seconds>'
example: 'framefromtime.sh PAL 56 28' would give you the frame at the start of 56m:28s in the film
this is the first shell script i've written to do anything useful so don't give me crap if it's not written well, it works and that's all i care about
ENJOY
Code:
#!/bin/sh
# Converts time in minutes+seconds to frames in PAL (25fps),
# NTSC (29.97fps), or NTSC/film (24fps) video.
