I've created an export setting. I would like to use it on several different projects created at different pixel dimensions.
1. I want to set the pixel dimensions as "From Source", but this option is not available. In the Presets list, I do see that Resolution is listed for several ready-made presets as being "From Source", but I do not see Resolution as being an available option when I create a preset.
2. How is Resolution different from pixel Dimensions? (not in the academic sense) I'm asking in terms of how the program handles the actual export itself.
