You are able to change the project settings for different resolutions and devices, but one resolution that is missing is the 4k preset. Specifically 3840 x 2160. It would be nice if this setting was added. What would be even better than this is being able to save the custom settings.
I've always been a little baffled as to why they don't have a 4K preset.
However, I use the preset "Original Recording Dimensions"in user preferences.That way, whatever clip is placed on the timeline first.Dictates the editing dimensions. Presets are inconsequential.
That's the way Premiere Pro and other Adobe products work.Plus it automatically sets frame rates and several other things Camtasia doesn't do.So it's a natural workflow for me. Try it, you might like it.
