So, when you apply the ‘Track Matte Key’ you click the ‘Matte’ option and choose whatever is in the layer directly above your distorted version of your footage.Īs for the other option ‘Composite Using’ this shouldn’t matter because you have a white shape. The middle layer looks up at the top layer and says ‘The only part of me that I want to show must be the same size, shape and position as whatever is in the layer above me’. Where you place this effect is very important as you need to have the shape ABOVE the layer you apply the ‘Track Matte Key’ to.
Now, with the title still selected, open up the ‘Motion’ controls and click the ‘Position’ stopwatch and animate your title shape through your video to make sure it stays over the item that you wish to hide – as the effect we are going to apply will only work within the shape that you’ve created.Īt this point we are ready to add the ‘Track Matte Key’ to the MIDDLE layer on Video 2. Title After These Effects Have Been Applied Title Before These Effects Have Been Applied Then, I apply a blur of some kind (Fast Blur in this case) and increase the blur amount until the edge of the title shape is nice and soft as seen below. I apply the Alpha Adjust effect and tick the ‘Mask Only’ option which makes the title shape a more solid mask (although this shouldn’t really be necessary if you have ensured that the shape is pure white). Select the title and then open your ‘Effects Controls’ panel.Īt this point I like to apply a couple of effects to get what I consider to be a slightly better end result. Once you have created the title, apply it to the empty track ‘Video 3’ and then trim it out to match the length of the video in layers 1 and 2. Gotcha! White Isn’t Always Pure White with a New Title So to make sure it is pure white go over to the ‘fill’ color section and ensure the little circle is fully in the bottom left hand corner of the color box. There is a ‘gotcha’ when you create a new white title – it seems that for whatever reason often the ‘white’ isn’t exactly pure white. Although not essential, it is probably best to also make this item white. Then, using the shape tools on the left, create an appropriate shape that will go over the part that you wish to hide.

Go to a point in your footage where the face (or license plate or whatever you want to mask) is fully visible and then create a new default still title.
While this can be done in a number of ways including the Circle effect or Garbage Matte, probably the simplest way is to use a title. All we need to do now is create some kind of mask to go over the area that we want to hide/mask. Just sure that the end result can still be identified as the form of a face or license plate but can’t be ‘read’ or ‘recognized’.įootage with the Mosaic Effect Applied with Settings of 50 & 50Īt this point we are well on the way to achieving our goal. Obviously, different footage will need different numbers so adjust them to taste. I increased the horizontal and vertical blocks from the default 10 & 10 to 50 & 50. To do this I applied the ‘Mosaic’ effect (which is found under the Stylize category in Premiere Pro). What we want to do here is add some kind of distorting effect that will make the face unrecognizable. This will create a copy of the video while leaving the original in video 1. Quick Tip: To get a copy of the video all I need to do is hold the Alt (on PC) or Option (on Mac) key and click and drag the video up into Video 2. Then, directly above the footage in video 1 I placed a copy of that video that I can apply some effects to. On the bottom layer (Video 1) I placed a copy of the video I want to use in its final form. To achieve the above result I setup my project with 3 layers… So how can you achieve this ‘ witness protection’ style effect in your video editing app?įirst, you need to think in terms of layers. Our aim is to end up with the result below (for this example we’ll leave as is and pass on chroma keying).

How do you hide things like faces, logos or license plates, as you so often see in news reports? All of this can be done with the Track Matte Key in Adobe Premiere Pro and (if needed) a little simple animation.
