We take the first 50 frames of a.mp4 for track a, and 24 blank frames followed by b.mp4 for track b. We then create a transition from track a to track b starting from frame 25 and ending at frame 49.
The output is stored in out.mp4
To view the results without saving remove "-consumer avformat:out.mp4" from the end.

recursively traverse the directory structure from . down, look for string "oldstring" in all files, and replace it with "newstring", wherever found
also:
$ grep -rl oldstring . |xargs perl -pi~ -e 's/oldstring/newstring'
Colorify colors input by converting the text to a number and then performing modulo 7 on it. This resulting number is used as the color escape code. This can be used to color the results of commands with complex outputs (like "482279054165371") so if any of the digits change, there's a good chance the color will change too. I say good chance because there's only 7 unique colors here, so assuming you were watching random numbers, there would be a 6/7 chance that the color would change when the number changed. This should really only be used to help quickly identify when things change, but should not be the only thing relied upon to positively assert that an output has not changed.

You'll want to use this for passwordless logins. Same as ssh-copy-id, if you don't have it on your system.
