scene or sequence?

hi! here I want to ask some question I wish they were not asked before:
what is different between "scene" and "sequences"?

and what is exactly "frame" and "dissolve"?

thanks ...

A scene is a continuous block of story telling either set in a single location or following a particular character. The ending of a scene is typically marked by a change in location, style, or time. In a shooting script, it can mean something different, but you don't really need to worry about that.

A sequence is the next biggest unit of story telling. It's a group of scenes (or just one scene) that fit together to tell a larger part of the story. A good example would be a bank robbery sequence. We might see the robbers gearing up in the car (a scene), then running into the bank and robbing it (a scene), then driving away, chased by police (a scene.) All those together is a sequence; each one is a scene.

It's an oversimplified example, but that's the basic idea.

A dissolve is an optical effect where the images of one hot are gradually replaced by the images of another. If you want a great example of a dissolve, rent "Lawrence of Arabia" and watch for the matchstick to sun dissolve.

People frequently mix up dissolve with fade. They're almost the same, but purists will disagree. Technically, you only fade to and from black; you only burn to white; and you only dissolve shot to shot. (I think. These things are frequently debated.)

In screenwriting, frame is a fancypants way of saying 'view.' As in "His big head comes into frame." I would recommend against using the word frame in this context in a spec screenplay.

I'm going to say something slightly different.

A scene is self-contained complete dramatic unit in the Aristotelian sense with a beginning, middle and end. In a scene the story and/or characters are changed by the end from where they began.

A sequence is comprised of two or more scene-fragments that individually are not complete dramatic units but collectively form a complete dramatic unit where the story and/or characters are changed by the end from where they began. Watch any Spielberg movie for examples, he is the master of sequence story telling.
