Thank you, Tom and Francois. It seemed to be the 29.97 fps that choked my ol’Vegas 13. 24.9whatever is going down better.
Now for the next issue: When palying back footage from the camera in Vegas and in Windows, when using the in camera IBIS, very ugly “frame tearing” was visible whenever I panned or moved the camera. This was freaking me out since I have to shoot tomorrow. After many tests with and w/o camera and lens IBIS and with IBIS digital off, I finally tried to render a clip. TG, that did the trick — no horizontal tearing. What in the world is going on with this camera?
