Important Update
If you have downloaded "Free Video to JPG Converter" recently or you recently upgraded it, you might be using the glitched version (1.4.1.3). You'll find out which version you have in the window that pops up before it starts:
In this version, "Save Every 2 Frames" doesn't work as it used to. Instead of creating 100 frames, it creates like 1000. So if you have this version,
change it from Frames to Seconds and set it at ".1"
If you have an earlier version like 1.4.1.1, you should be fine.
