DGPulldown Publisher Description
DGPulldown takes a progressive MPEG2 video elementary stream, and applies pulldown flags to change it to a higher legal MPEG2 output frame rate. It also allows anging/correction of timecodes. It can apply traditional 3:2 pulldown. It also can convert 25fps PAL progressive material to NTSC. It allows you to encode your movie to MPEG2 at 25fps using progressive encoding. It uses irregular pulldown patterns for PAL to NTSC conversion.

...... It allows you to encode your movie to MPEG2 at 25fps using progressive encoding. This saves a lot of bits and therefore allows for much better quality with the same bit budget. Also, compared to methods that first slow down the video and then apply 3:2 pulldown, there is no need to process the audio.
The great idea for using irregular pulldown patterns for PAL to NTSC conversion was first suggested by 'Xesdeeni'. An extensive discussion of the theory and usage of DGPulldown can be found at the Doom9 forum.
Pulldown of 25 fps to NTSC
A typical workflow is as follows (assumes you are starting with PAL source material):
* Demux the video and audio streams.
* If the video is interlaced, deinterlace it to make it progressive. If it is already progressive, skip this step.
* Resize the video to 720x480.
* Encode the video to MPEG2 at 25fps progressive.
* Run DGPulldown on the video MPEG2 stream to flag it up to 29.97fps (using the 25fps --> 29. ......
