I do lot of work for TV where we mess with Youtube clips. Often they have an odd frame rate. Kind of a 3/2 pulldown type frame repeat. Roto on this stuff or motion tracking can be quite problematic due to the duplicated frames. Anyone know a way to strip these clips to a non repeating frame rate? Have tried posterize time and taking them all the way down to 15 fps and still get repeats.
As this is a network tv show, they have a large pack of lawyers making sure we are within the bounds of parody or whatever classification is appropriate. Believe it or not, many popular mainstream shows rely on youtube as a video archive of news stories and other video files. Its crazy that we have to do it this way, and we do have a team that does nothing but watch and tivo, but they cant catch everything.
Anyways, we capture using one of the many free online capture programs (keepvid i think). We have tried commercial apps for this in the past and had less luck than the free ones. You cant go frame by frame on youtube so I cant tell if its getting converted by these apps. I highly doubt it as that would require processing time. The weird frame rate is built into the clips when they are downloaded.
