When you export dxv on Adobe Media Encoder using Quicktime, don't need to set the specs for every file. You can make a preset and just drop it. Those presets have the ability to take parameters from source file and match it. See here (based on source): https://www.mediafire.com/convkey/630c/e6hi7hy1...
About spacing Y, I was asking myself the same, why not more negative values?
Solve it decreasing the font size to get the right leading, and then scale it.
Isn't the usual way to adjust leading, but works.
You can't use it inside resolume right now, maybe some of these days..
I was using the ISF editor as external fx module, sending image from resolume to ISF, then come back to resolume (through syphon or spout).
