Sallly,

For a jump start to Terry's method you can use some of the options under Effects > Design elements > Picture-in-picture.  They are presets of various size and position settings. Though the presets are called picture-in-picture, the effects will work as well for video-in-video. As Terry said, arrange your clips on four tracks and drag in a p-i-p onto each one. It's best to start with the bottom (higher number tack) clip first as it is 'in front' of the others so you can see what's happening. Time offsets are optional -- and you can even have transition happening on each track as well though you may find your computer struggling to preview everything.

The presets may not have exactly what you want, but after you apply a p-i-p go to the size and position movement effects window and make any adjustments. If you tick for values in '%' rather than the default values in 'pixels', it will be easy to create your design in exact matching sizes. For frame filling quarters with no borders at all set each clip position to either 50% left and/or 50% top, and all sizes to 50% height and 50 % width.

Note: You will need to ungroup your audio tracks and delete or mute all but one otherwise you will have four sounds playing simultaneously.

Added: I'm in error above. As John reminds me, you don't have to delete the extra audio tracks, just mute them 

Regards,

Hi Sally,

You have been getting the royal treatment. I would like to add my little bit.

You can also add in a mask to frame your videos. This simplifies the process a bit and makes it aesthetically pleasing, at least in my opinion. I searched through some of the many programs that I have and I found a 4 screen photo album mask. You can make your own in Paint or another drawing program or search through your computer for bmp, jpg, png files and scan through the icons as I did. You may find some surprises.

In the screen shots below you will see firstly the album mask with the videos and secondly the overall MEP screen showing the clips on the timeline that fill the images. I did not include a fourth, but I could have. All are videos, each in its own window. In the second screen shot, you will see that they are one on top of the other, but using the effects, size tools, I scaled them down to fit. Even if the exceed the frame it doesn't matter as they are behind it. The third image in the lot is actually a Section (a zoomed in or cropped area) and then used size/position to put it in the frame. Because I am using a mask on the lowest track, the video images are all behind and only show up when they are in the window. To see each one by itself, click on the S at the left of the video track and it will hide all other tracks. (Note that I didn't change the length of the clips to match the mask, but I should have. This was done quickly just for you.)

Note that I have muted 2 of the 3 tracks, otherwise you can get a mess of sound. You can mute all the video tracks and add in your own audio on another track.

Enjoy!

Hi Sally

This my method which is using Terry's and Carls method but adding one extra image to create a simple border between the images.

John CB's advanced method is great for putting the videos inside decorated borders.

In this example I am ssuming you are quartering the screen and the project is set to 1920 * 1080

Put the four images / videos on the timeline and resize and position them as in Carls and Terry's method'

Add a solid colour image to the timeline 2 times on tracks below the previous four - see image below, in my example this is black image.

You end up with the tracks looking like this

Using the Effects Movement Effects, Size/Position select one (black) image, uncheck Keep proportions - see image below

Change the width setting to the width of the project - 1920 - and the height to say 20px and top to 530  - this creates a horizontal black bar in the centre of the screen.

The top setting is half the height of the screen - half the height of the black image as shown below

Click the second black image

Change the height setting to the height of the project - 1080 - and the width to say 20px and Left to 950  - this creates a vertical black bar in the centre of the screen.

This sounds complicated however is actually quicker to do then it is to read.

The finished example looks like this hi res image - note the dotted lines indicate that the horizontal black bar is selected on the timeline.

HTH
