This may be a purely DVDA question, but may relate to how a clip is prepared in Vegas, so here I go...
In DVDA, there are black "ticks" (small, inverted triangles) at the bottom of the clip on the video timeline. These markings never appear to align with anything on my projects. Frames appear to align in sync with the "Time and Frames" ruler, but not the "ticks".
I always keep Quantize To Frames activated in both Vegas and DVDA. The quality of the finished DVDs are excellent.
What are the ticks and should they be of any concern?
Thanks
