[Rafael Amador] “When going 29.97 to 23,98 the only thing needed is to drop some frames.”
I was going to jump in with a big “whoa there!”, but the discussion has progressed.
Correctly, you both have come to the conclusion that you need to make a choice. In this case, going from original 29.97 to 23.98 is not at all straightforward. No, the math does not work out, and the choice will be between spatial and temporal resolution.
You will either end up with a quickly achieved, but compromised, output, or a slow, but high quality result — if you choose a software process. Find someone with a hardware processor if you need “Fast” and “Good”, but “Cheap” may not be available, as per usual.
I seem to be doing frame conversions on a regular basis now. (Have Teranex, will convert.) So, in this case, having built it, they are coming.
Alos taken aback somewhat by the relative ignorance about frame rate that so many digital camera operators are exhibiting, but its mostly confusion about what the camera is producing and what the recorder is actually putting in the file.
