One of the underappreciated features of the MPEG-2 format is the repeat first field feature, which allows a pulldown to be created from progressive frames on playback. This is usually used to encode 24fps film material to NTSC MPEG-2, but it also makes it possible to encode variable framerate MPEG-2. Some types of video (such as TV shows, anime, and music videos) alternate between 24fps and 30fps framerates, and normally these types of video have to be encoded interlaced in order to accommodate these framerates.
Over in the "Other MPEG-1/2 Encoder" forum, I released a modified version of the DGPulldown utility that makes it possible to make variable framerate MPEG-2 from a MKV timecode file, which can be made automatically using an AVISynth filter such as TIVTC. See this thread for more details and to download the modified DGPulldown.
Because it works with any encoder, including CCE, I am posting about it here so that anyone who is interested can test it and leave some feedback and/or suggestions :D, either in that thread or this one.
(mods: i apologize in advance if i am cross-posting here, if the forum had a place for discussing all MPEG-2 encoders i would have posted there instead...)
