I’ve been testing and it seems best to go with the “HD 422 1920 1080-60i” option, it retains all the quality.
Working very well so far. I drag and drop the mov files straight onto the timeline, no more difficult than dragging and dropping into a regular video converter window.
Don’t forget that you can create a new specific render template if you so wish and save that. Now restart Vegas and when you go into your Batch Render your new render template will be available under whatever codec family you created it under.
You can also install the free GoPro Studio which installs the Cineform VP5 encoder/decoder on your machine. With that installed you can do all your batch renders to Cineform.avi. The Cineform codec is a very high quality wavelet based codec which runs very smoothly in Vegas. Going way back to HDV days and I think it was maybe in Vegas 8 that Cineform.avi was a standard intermediate editing format. It’s the codec of choice for me for HD and 4K work without a doubt.
