I think 3Point means the "Auto Color Levels" out of the Grading Panel should batch affect selected Events. This isn't possible via Vegasaur and I think at least no such a script exists yet (if a simple script could do this at all). It is not same as just applying the FX preset. It needs to trigger the Auto Level process each time anew so that each Event will get its own individual white balance applied. Maybe an extension could do this.
@joelsonforte.br Thanks for your efforts, but this is not what I meant.
It's like @Marco. explained and as shown it this screenshot. The script should open the Color Grading panel and adding the Auto Color Levels to an event, than select next event and adding again Auto Color levels, and so on for all events on the track. It would be great if this could be done with a script, because manually doing this is quite time consuming. In my screenshot you can see the result of the Auto Color Levels in the right half of the preview.
@wwaag, known for the HOS (Happy Otter Scripts) was so kind to develop a batch auto color level script with the use of the Color Grading Panel, as I requested.
The final script will be released at HOS.
My special thanks to wwaag for his efforts and quick response.
I'm the first to admit that this is really a kluge, but it does seem to work OK and it will save some time for those wanting to apply the different Auto settings.
