      I'm a newbie and I'm trying to make a video with what I think is a "basic" effect, but I have no idea how to get it done. Here's the project:


      I'm going to record a video of me holding a set of cue cards, and going through them one by one while I speak on camera in a sort of presentation. As I go through the cue cards, I'd like to embed some YouTube videos that I've downloaded onto the face of particular cards in the set. So as I speak in the video, I show a new card, and the video is "playing" on the new card that I've exposed in my presentation. I then pull a new card out and there's a different video "playing" on the face of that card.

      Can anybody help me?

      If the cards used are green, you can use a green screen.

      I personally am using Corel Video Studio pro X5.

      In that software what you want can be done very easily.

      It also does not matter what color the cards are, but it is a lot easier if the are stable like on a table or something.

      Place the videos on the time line in an overlay track, and pin the corners to each respective corner of your video cards. The cards do not even have to be level, as in they can even be tilted. 

      I am kind of a newbie myself, but forced myself to learn Corels software as I produced a Wedding Montage/collage for their reception and made a video of their cerrimony. Both were done wonderfully using the corel software.

      This is called "compositing." You'll need either appropriate editing software or external applications such as PhotoShop or After Effects to do this.


      In Sony Vegas, for example, I would do this as a Picture-in-Picture. Download the YouTube material, create a P-in-P and insert it into the cue card, using key frames to move the YouTube material as needed to keep it inside the cue card.


      The current (October, 2012) issue of Videomaker Magazine has an article on compositing that may be useful to you with your project and you might also take a look at, a good tutorial on Picture-in-Picture.

      Thanks for the replies so far. The software that I'm using is Adobe After Effects CS5. I'm a total newbie to video editing. However, I have a very strong working knowledge of Photoshop and Illustrator, so that might help me to a certain extent… maybe not much. : )

      So far, I don't really know what color cards I should be using. I could use green or blue cards. I was wondering what the implications would be if I was using all green cards, because if I were taking one card out from behind the one showing, and they were both the same color green, would it make it hard to distinguish where one ends and the other begins (for the software I mean)?


      Any suggestions on implementing this project are 100% appreciated.

      Although you don't really have to, it will be a lot easier if you were to switch between colors so that no one color appears on screen on any two cards. This will allow your software to target one card and place your footage on it without it appearing on another card or without you having to manually prevent that from happning. Go green blue green blue green and so on.

      If you've using After Effects CS5, read up on Motion Tracking.


      Assuming you're using white cards against a different-couloured background (for contrast), it should be able to track the corners of the cards with a few tweaks to the settings.


      Use the Corner Pin setting and it will conform to the rectangular shape of the card while you move it around. Then you can draw a bezier curve (same as in Illustrator) as a mask around your hand / anything else obscuring a clear view of the card using the Pen tool, and keyframe it to follow the action.

      mercedeslens is giving you the best advice on this effect. If you make marks on the corner of each card it will make it easier for the Point Tracker to follow. I would also label each card to keep track of them. In general when doing the Motion Tracking you are going to place your video on top of each card so using different colored cards so you can key them out isn't necessary. Assuming the cards are a regular shape using masks should do what you need to hide parts of each video when necessary.

      One word of advice when using motion trackers, in general you will want to apply the tracked data to a null object layer instead of the actual video layer you want to follow the cards. This gives you an extra level of control.
