whats the best option for frames

When i cut and delete bad scenes then I join together good ones. What's the smoothest and standard away to do it? how many meaning the number.

You can either hit the Backspace key to delete the shot(s) and leave the timeline open, or you can hit the Delete key (to the right) to remove the shot and close up the gap. This is all covered in the manual.

For anybody new to Resolve Editing, be sure to go through the free textbook & training videos:

"The Editor's Guide to DaVinci Resolve 17"

available on Blackmagic's Training website:

You'll find these are enormously helpful, even if you have experience with other editing & color platforms. There's tons of shortcuts covered, which will help cut precious minutes off every session. The 4060-page manual is good as well, but the textbooks present it in a much more concise way. (Coming soon is an update for Resolve 18.)

Are you talking about dissolves or transitions?

Sorry, but it's hard to get what you are talking about. It may help if you first cover some of the free training supplied by BM.

Do you mean a transition? That has nothing to do with cut and delete. You can set up Cross Dissolve (or the other transitions) for any standard default length you want -- that's covered in the training.
