[QUOTE="tourettes, post: 530153, member: 10858"] In PAL interlaced content the actual frame rate is 50 fps, and if you use BOB or WEAVE deinterlace methods you will end up in 25 fps second as there will be lot of data that is just discarded. If you are using vector adaptative etc. (mostly HW based) deinterlace methods the result will be 50 fps (where every frame is unique, no duplicate frames). This is because the single frame is actually containing only half of the vertical lines and after deintrlacing the half of the data is "generated" based on the analysis of few frames and their motion vectors. [url=http://en.wikipedia.org/wiki/Interlace]Interlace - Wikipedia, the free encyclopedia[/url] I'm pretty sure that such case doesn't happen 25fps interlaced content. It should be always 50 fps interlaced content. [/QUOTE]
