[Lex Computer & Tech Group/LCTG] Computer graphics question

[Tony]

Jonathan,

I have something that with some modification might help you get that 
information.

_/*Question*/_: Youtube videos list the running time (low-left part of 
frame) at rounded-off 1-sec intervals. Would the 1-sec tolerance be 
sufficient for your needs?

_/*Comment: */_My tool is MATLAB-based but we can work around that.

Please call me off line to discuss, if you have not found an alternate 
solution. I will follow up with a call, too.
