Milliseconds to Frames

Hi,

I extracted an SRT file from a m4a podcast but the times are in MM:SS, of which the seconds are also containing milliseconds.

I want to convert these times to SS:MM:FF (frames) but I have no idea how to convert the milliseconds to frames...

E.g.: 13:45,875 (13 minutes and 45.875 seconds) to MM:SS:FF?

Regards,
B

One second has 75 frames, that is 1000/75=13.3333 ms equals one frame. So you have to round up or down the value. 13:45.875~13:45:65
Exactly it would be 13:45:65.625

Cheers

If your movie is 25 frames per second, then a frame is 1/25th of a second, or 4 ms.


eevan: where did you get 75?

That should be 40 ms (probably a typo)

I stand corrected.

@Juha: But we are talking about video frame-rate/timecode aren't we?

Ofcourse ... just wanted to point where he digged that value from.
