If I will open up the Photoshop folder, I can see different Photoshop’s sources that are used inside this project. Here I click on twine crop PSD. In the top of the project pane, I can see a small thumbnail view of what this image looks like. Additionally, I can see the name of the Photoshop document here. It is a small arrow, and an indication that this Photoshop source is used four times throughout this project. The small arrow can be click revealing each one of those four places, where this is used. Clicking again closes up that window.

Below it, I can see the size and pixel aspect ratio of this Photoshop document. Then below, there is an indication that is colored up, is million of colors, plus meaning, plus an alpha channel. The alpha channel is now interpretive as a straight alpha. If I move down, and choose AB Snowflake Movie, instead of seeing the information for the steel, I see information for the movie. Here I can see that it is 360 by 243 pixels, square pixel ratio. It is six seconds in duration and running at 30 frames per second. It is million of colors, but without the plus, which indicates there is no alpha channel on this movie.

Last, is photo jpeg, the compression codec used to create this movie. At the top, I see it is called AB Snowflake Movie. Clicking on the small arrow reveal that it is not used. Similarly, if we take a look at our music, we can take a look here, by clicking on either one of these AIS, and seeing that the thumbnail at the top does not display video. Zero by zero pixels means, there is no video to display instead; we have got seven seconds of audio. We have a small icon here for a way form, and we see that the audio has been recorded at 48kilohertz, 16bt and stereo pair.

We knew that after effects CS3 is the ability to rename our source. We will click on the source AB Snowflakes Movie. With that click, we use the return key on the keyboard to open up the dialogue box to rename the source. It is important to know, that this can be a very confusing as a beginner. But, you make it a file that has a rename source in it. We will call this- Digital Snowflake and uses enter in the number path to accept it.

In the source column is called Digital Snowflake that a movie. But, if we look at the file path, we will see that it is actually coming from a source, called AB Snowflakes that a movie.
