But some movies have the 3:2 pattern change throughout the movie, So a deinterlacer is useless against those. When you just use a plain deinterlacer back to 24 FPS, you run the risk of the encoder dropping frames and duplicating others, leading to major choppiness. They are stored interlaced at 30FPS like a vhs tape. Most films are stored progressively at 24 FPS (soft telecine), but some are not. is that the dvd may be a film with 3:2 pulldown (telecine) hard encoded into the video. You can deinterlace to 60FPS, but the methods are not easy to do and im not quite sure if the apple TV will play them.
Mpeg4 and H.264 dont to well with interlaced frames. So what they do is chop out 1 field out of every frame leaving only half the motion, and back to the choppiness.
Well most encoders try to deinterlace fields. So american television is actually 60 Fields per second, and when played back on TV, 60 FPS is what you get. Each field contains one whole fame, so every real fame carries 2 interlaced frames. Video in America/north america is 30 FPS with 2 fields in each. If your source is video as in home movies and TV shows( not all tv shows), you have interlacing issues. When played back, it leaves a slight annoying stutter in the motion. The encoder has to double every fourth frame. If you set the encoder to rip at 30 fps, or some may be defaulted to that setting, you will get choppy video. What type of dvd are you ripping? Movies, tv shows, home video? If they are movies, they run at 24 FPS (23.976 to be exact). Free Audio Converter enables you to trim wanted video and audio. Edit audio files and change audio settings.
