Disappearing layer in aftereffects

Half way through making the logos creative I noticed that on some of the photos the logo started to disappear. I looked on the Internet ‘disappearing layer in after effects’ and some answers were because the logo is a png file although my other png logos are working. http://forums.adobe.com/thread/783940

After doing more research on the Internet I didn’t find any results. I decided to take the png file and opened it into Photoshop to convert it into a jpeg and Photoshop file. My teacher did do some research also and it said that the png files wont disappear if they have alpha channels switch on with is done while saving the png photo in Photoshop but unfortunately I couldn’t do this nor could I do this on any other file type. Instead I put the new photoshop file logo into my ident, when switching it to 3d on the photos it disappeared so I’ve kept it 2d and have started to make the logos move. 

making logos more creative

since i managed to make camera movements on my photos, my teacher had the idea to make the logos move on the photos. to do this you clicked on the logo's layer, open a button call transform and you can choose to make the logo go left or right, u or down, diagonal, flipped upside down or backwards. again when you choose what you'd like your logo to do it creates check points so as the logo plays through it hits check points which tells it what to do.

I read this online tutorial about camera movements across the photos to make my ident more interesting and eye catching. I had to convert my layers and logos into 3d layers and put a new layer in which was the camera movement. When you opened the camera layer it brought you to a button called ‘transform’ which lets you choose what camera movement you’d like on the photo. I did this on all of the photos I have, when you do the camera movement it opens ‘check points’ so as the camera movement moves on in the photo it hits check points which tells it what to do next. 

new chosen photos

Unfortunately the previous photos i intended to use were too small to fit on the after effects screen. When i scaled the to the right size they were very pixelated and blurry because the photos were so small. So ive chosen some different photos and some different monuments that are a lot bigger in size so instead of having to make them bigger causing them to be blurry I just have to make them smaller.
