While you can load Vegas Pro 9 and 10 files into Vegas Pro 11, there are considerable compatibility issues.

If you did a lot of compositing, espcecially with “chroma keying” in an earlier Vegas version and load file into Vegas 11, be prepared for for some hallucinogenic experience! Of course I first suspected that this might be an experience limited to my computer for whatever reasons. However, it was fully reproducible on other computers.

I contacted Vegas customer service and technical support and they confirmed that there are compatibility issues because the plug-ins are structured differently. Further to chroma keying a sequence of effects such as with “soft contrast”, “color correction”, “fill light”, etc. results in something entirely different. It will end up in doing all compositing from scratch in Vegas pro 11. Sony technical support seriously suggested to render out the pieces of footage that have effects and load it into Vegas Pro 11.

In effect it will be wise to keep Vegas pro 9 or 10 together with Pro 11. What makes me worry is the future. Sooner or later the older Vegas issues won’t work any longer with future Windows editions.

Strangely, these compatibility problems with Pro 11 are not communicated anywhere!

For me this a “make or break” point. Do other programmes such Adobe Premiere Pro also have such compatibility issues with new releases?
