Software developer (in love with C++). Hardware geek (FPGA's, STM32, AVR, crazy stuff from discrete components), love LED indicators (7-segment, alphanumeric). Trying to understand ASIC design & manufacturing better at the moment. Also, trying to wrap my head around lens design, but that is not going to be that easy.

At least it gives 50 fps output, but unfortunately 2 sequential frames generated are very similar... While when I step original 50i video frame by frame I really see that fast motion have twice more 'steps', and much smoother.

Well, in mediainfo file have 100 FPS, but I am still getting just 25 FPS on the player. When stepping frame by frame it's exactly 25 FPS.

@Jason Well, my videoplayer (GOM Player) deinterlaces 50i video, and shows it smoothly (i.e. at 50Hz) on my 120Hz TFT monitor, which is obviously progressive. Why can't video recoder do the same thing, and produce smooth 50Hz output? I understand that 50i have less small details, but why can't I expect to get 50Hz output?

Unfortunately, it still produced just 25 fps output... Original file is way way smoother.... Even adding -r 50 didn't helped.

comment Mean Time to Failure (MTTF): When disk manufacturers post this, how should you interpret their numbers?
@Federico Russo : Why? You think it's just a usual developers error, causing HDDs to lock in a non-recoverable state after certain number of hours?
