The video volume was too soft, so I ran the them through a program to make them louder but the video had to be less than 500Mb. The last 3 videos were larger than that, so I ran them through another program to make them smaller. Then I increased the volume. Unfortunately these last 3 look smaller, but when viewing them you can make them "full screen" and they are bigger on a PC (but still not so big on a tablet). The sound is better but on some devices you still have to turn the volume up!
