I like to have never found the save video option under the file menu. Why not hide it next time. lol I can't blame it on my glasses this time either. I got new ones a while back. Maybe it is stupidity. o_O I will say this tho, it is dang fast. It took like 10 to 15 seconds and it was done. Kdenlive took MUCH longer. File size is awesome too. The two files added are very close to just adding the file size of each video. I'm talking within a megabyte or two. Thanks for this tip. I got a new toy to play with. lol Dale :-) :-) -- I am only responsible for what I said ... Not for what you understood or how you interpreted my words! Miss the compile output?
