Thanks for the suggestion! I originally was hoping that we could "render" a couple of clips together, then I realized that we can Record with Alpha and so smoothly - and we get (about) the same result, at least with DXV clips. I guess rendering the clips would give a better result (surely in higher resolutions / with Prores) without any chance of glitches or so. But from extensive tests I made with recording DXVs I'm amazed by how smooth it is.
Regarding rendering a column: why not have all the current playing clips render together no matter where they are? I mean, why need to place them in the same column, at all? One other limitation I'm currently having with the render feature is that it's impossible to render a longer clip than the original one: say I have a cloner effect on a 16 sec clip - but the clones are completing a whole master rotation in 32 sec - the result is 16 sec long and not looping. So, having the render pull the length of the longest clip might be limiting, cause there are cases where I would like things to run multiple times in order for all the clips (with their effects) to close the loop.
I suggested Resolume to add an x time multiply to the render feature, too. I might need to bring "Render x times the original length" to vote in a separate feature request ))
What do you think?
