Take a screen shot from a video

Introduction
If you play a video on a Windows PC you can't take a screen shot. Press Print Screen won't give you anything. If you use Greenshot or other screen shot utilities, again you'll get nothing, just a black screen! Then I came across the solution. I'm using VLC Media Player and I noticed it actually has a built-in screen shot function!


Instructions
In VLC Media Player, play your film, press pause at the screen you want to capture.

Click Video | Take Snapshot

An image file (PNG) will be saved in your My Pictures folder. 

Change the default save location

To change the default save location click Tools | Preferences

Click Video and change the 'Video snapshots' Directory (click Browse to select a folder)

Click Save

For this change to take effect you must close VLC Media Player and re-open it.

Excel 2010 - Add times together (duration)

Introduction
I had a number of videos of varying duration. I wanted to find out if I watched all the videos one after another, how long they'd all take. I needed to sum the duration of the videos. At first I put the values in Excel in the format mm:ss (minute:second) but Excel didn't like that. I found that it works if you enter the times as hh:mm:ss (hour:minute:second).


Instructions

Enter the values hh:mm:ss - even if your values are shorter than one hour, as mine are, make sure you enter them as shown here with a preceding 00.

Select all the cells including an extra one, this will be the total.

Format the cells as Time (as shown in the above screen shot).

Click in the empty cell at the bottom and click AutoSum

You should end up with something similar to the following:
