3:2 Pulldown and Non-Interlaced source

[Entropy_Controller]

I have read that 3:2 pulldown is used for converting from 23.976 to 29.976 fps, or something like that. The part that confuses me is, can you use this for both interlaced and non-interlaced sources??? Or do each of them have a different fps???

My source is 23.976 fps, as it states in DVD2AVI, however I am confused as to whether I should choose interlaced or non-interlaced and whether or not to use 3:2 pulldown to get the best quality picture.

Please tell me which will result in best picture.

Thanks

I think I found my answer, that my film source of 23.976 fps, is a non-interlaced source and that 3:2 pulldown should be used.

Is this correct???

it might help you a little
if nothing else it's an entertaining read

The video tab lets you set the output for your encoded file, the top of the advanced tab is where you tell the encoder the properties of your source. If there were anything that outright conflicted than I'm sure TMPGenc would not allow you to set them as such.

As far as the 3:2 pulldown while playback option is concerned, it does not matter whether your source is interlaced or progressive. The simple rule is this, if you are encoding mpeg2 (SVCD or DVD) at 23.976fps then always include the 3:2 pulldown flag, and if your using TMPGEnc than that means always use the 3:2 pulldown while playback option. Do not confuse this with the 3:2 pulldown filter on the advanced tab, this is for performing a hard telecine which rarely will ever be needed.

If your source is non-interlaced then let TMPGenc know by setting this option in the advanced tab. Also set the aspect ratio of your source. From there you are free to use any output settings that aren't greyed out.
