create and upload a very simple text frame video

this is a short and easy project. just use any simple video creator tool and create a 30 second video that is nothing but a text frame (all words). If this project works out well we will do it again and add an audio track too. Here is the key: the text needs to be in a large white font on a black background. AND WHEN IT IS POSTED/UPLOADED, THE THUMBNAIL THAT CAN BE SEEN BY ANYONE MUST BE READABLE (the text must be readable) BY A VIEWER WITHOUT CLICKING, SO YOU WILL NEED TO BLOW UP THE TEXT AS MUCH AS POSSIBLE TO ACHIEVE THIS. I KNOW IT CAN BE DONE I HAVE SEEN IT. I will supply the actual text to use, it is only 5 words (4 smaller words and then 1 larger word). And the video is to be slightly varied and saved and uploaded to youtube as 20 unique video files as a video response to each of the top 20 music videos on the front page of the "top music" category. Potential to turn this into a long-running project as well.
