@IgorBeg Yes, the purpose is to Ingo, which you can do more directly through Settings --> Format --> aspect ratio. But I wanted to put this direct "Aspect Ratio" option also in "Resize Track", because it can be convenient to have it on the individual tracks in input instead of on the whole project in output. @All The topic "aspect ratio" is not very important for CinGG because it mainly concerns the cinema and to a lesser degree broadcast TV. But I'd like to make "resize track" (and "Info --> Resize", too) suitable for changing aspect ratios of one track, similar to what you can do in Settings --> Format for the whole project. Basically, I suggest we add an entry "Aspect ratio =... ..." that only affects the viewport of a given track. It is not a very important addition, because you can always do a simple calculation and get the desired result. But it is an exquisitely professional addition, always present in the most famous editing programs, and I would like to see it on CinGG.
