Like many others that have used VEGAS since the MAGIX purchase, we experience weird/random,explainable crashes. Turns out if you go in to the special Internal settings, you can turn So4 Compound Reader for AVC/M2TS from TRUE to FALSE and that will clear up 95% of those random crashes. The only downside (that I'm aware of) is that VEGAS no longer can read 10bit media when it's set to FALSE.
So my usual process is to set it to TRUE to edit my DSLR footage, fully correct, grade, and edit it, render it in to an 8bit format. Then I turn So4 to FALSE and then start my actual project. This allows me to get it completed with little to no crashing.
So my questions is this. Can you add a toggleable option somewhere easy to find that can quickly disable and then re-enable the So4 Compound Reader? I know you have to restart VEGAS every time you change it but that's okay. You can even add a little pop up warning box explaining what happens when you turn it off and that you need to restart VEGAS for it to take effect.
