Adobe - Premiere - need to add 140 titles! How!!

I work with Premiere for projects on my evangelism website, and it did a bunch of footage, but I need to add titles.   I did not want to have to open, cut, past each set of title in each video. 

I heard that you could use Adobe InDesign (video: How to update multiple titles in Premiere Pro using InDesign), but I didn't have the latest version and didn't feel like learning a new adobe product like InDesign.  Maybe later.

So, I decided to use Powerpoint with no background, create my title label in the lower-thirds, save each file out as a *.jpg.  But that creates a file with a white back ground;  it needs to be transparent *.png format.  After a little digging, I found a utility called ImageMagick that would remove a white background and make it a transparent png.

command used was:
convert -transparent white whatever.jpg whatever.png

I used a command shell FOR loop to do the conversion.  Now, I can at least import the png files and change them with PPT and ImageMagick.
