Problems with exporting videos - Lucy

Over the past week, I have been creating all the tickers for the news report on Premiere Elements since trying to export them from After Effects. Surprisingly, I have experienced many new problems while trying to export the video onto the Mac and then onto YouTube, and these problems have been very inconvenient for the whole group as we couldn't move on in regards to progression. I also spent a lot of time trying to export the videos which meant there was a lot of time wasted which is very annoying. 

For the first try I exported the video on to the Mac with no problem, yet when I uploaded it to YouTube the tickers were all cut off from the bottom of the screen (see video below)


Then for the second try, I exported the video to the same format yet the screen went blank when trying to play the video on the Mac so I therefore couldn't upload it to YouTube (see screenshot below)


In result, I have exported the video to a different file format and the tickers are in the frame with no problems. I put the video onto my memory stick and copied it on the other Mac where Anna is editing the report, instead of uploading it to YouTube. (See screenshot and video below.)
