Some notes when making video on your own.
video taken by camera which was in some format unreadable by tracker *.MPG.
use Free Video Converter: Any Video Converter Freeware to convert to *.mp4 a format that tracker can read.
important notes are:
select customized MP4 Movie *mp4
select [b][color=green]Frame Size ==Original[/color][/b] you don't want a small frame size to analyze motion
select [b][color=red]Encode Pass == 2[/color][/b] very important else there may be frames that don't change thus the data from tracker will be poorly tracked!

Good luck!
