Can you talk about a recommended workflow using 5D & 7D DSLR formats with Vegas Pro?
You can use all of the same editing techniques with these files as with any other. You will probably see better preview playback performance if you match your project properties to the source media. To do this, choose File | Properties and click the Video tab. Click the Match Media Settings button. In the Open dialog box, navigate to and select one of your source files, then click Open. This sets your project video properties to match your source footage.
