Long time users will use the terminology but as Walter suggests, the HELP file will usually fill in the gaps. If you don't understand, feel free to ask more questions. We are all eager to help and show off our knowledge. :)😬

I was having trouble getting the fade in and out tools to work. They usually do, but not today. I came here for help. Someone suggested moving the Composite Envelope down and out of the way. It worked great... once I figured out what the Composite Envelope was. I'm a long-time user, but I don't always have the right terminology. I don't work with other users, nor do I communicate with them, so to me, it's that blue line at the top of the video track that moves the video between 0% and 100%... the fader or dimmer, in my mind.

I'd like to respectfully suggest that when certain terms are used, they are defined as well.

Thanks for the help, and for considering my suggestion.

Composite is sort of an skeuomorphism (not sure if that helps...) and dates from the early beginning of photography (like 1880 or so).

Lot's of stuff in modern editing is still referred to as analogue terms, even GUI-wise (with knobs and sliders and handles).

Simply said "composite images" are two sources, blended together (hence the fade).

Photoshop has it's composite engine, Vegas has and even in programming (low level machine language) you can create a composite when doing OOP (Object Orientated Programming).

Today, it's kind of abstract but it's sure "more than opacity" (depends on the state of composite you want to achieve).
