The effect differs from the preset provided in the standalone application.

Does anyone know why the VHS image differs from OpenFX between the standalone application?

I use OpenFX in Vegas Pro 13

There are two reasons:

• The standalone application is downscaling the input video to 480p before processing it, but Vegas is not. See the documentation for more information on how this affects rendering.
• Some settings are set to have exponential growth instead of linear growth (like the "snow" setting), to give users finer control over them. I believe this is currently not being applied properly to presets in the OpenFX and After Effects plugins; I'll try to fix this in the next release.
