Hmmm, it'll look smoother on a computer display. For TV viewing unless you have a progressive scan TV set then you'll still be viewing ~30fps interlaced. > And, isn't the size difference just a nice confirmation that a ~30 fps > telecined stream has approximately the same information content as the > 24fps original stream? It is nice to know that yuvkineco is doing a good job of removing the duplicate fields - that's true. But it still doesn't give me a good feeling for why encoding those duplicates (which fields from different frames) doesn't take more space. When doing a analog->digital capture you're actually getting the duplicated/mismatched field since the capture process doesn't know the data originated from film. To the capture/encoding process you've got 30fps (that could just as well be from video tape) to encode. Dropping 20% of those should, I thought, give more than a 1% difference in final file size. I'll take another look on the next tape - perhaps it's data source dependent and different tapes will come out differently. Oh well, it's off to try and resolve https://sourceforge.net/tracker/index.php?func=detail&aid=1215231&group_id=5776&atid=105776 one and for all. Seems PPC building on Fedora is having problems (not sure what Redhat did to gcc4 to cause the problems - gcc4 on OSX doesn't have the issues).
