Telecined encoding...

[vigi_lante]

Source is captured from TV using Huffyuv (YUY2). And I'm talking about NTSC film content (telecined of course, not truly interlaced).

So, I would like to know if this script above, for example, would be the right way to process this telecined video (in order to keep it interlaced)...

AviSource("c:\capture.avi")

JDL_UnfoldFieldsVertical(true)
PixieDust(5)
JDL_FoldFieldsVertical(true)

(I will not resize)

...and if I need to turn on the "Interlaced Enconding" on XviD (or if this is only for truly interlaced).

Thanks.

If it's telecined, you don't need to encode as interlaced. IVTC it to get the original, progressive frames.

I know, I know...but when the source is telecined, it's impossible to get all the original progressive frames back. And since my target playback display is a interlaced TV, I think you can get better results if you just keep everything the way it is.

I know that you can get good results with IVTC, but I'm looking for something ever better.

Where did you get this idea from? I'd be interested in seeing it in black-and-white if possible. :)

NTSC Telecine if done properly is a completely reversible process.

The only time where the orignial progressive frames cannot be restored from a telecined clip is when the clip contains a mixture of 23.967 fps and 29.97 fps content, or if the clip was improperly telecined.

But to answer the initial question, looks OK, although I'd use a standard stupid bob since you're not resizing. That will make processing slower though.

You might want to check the RemoveGrain thread, there are some very good (and much faster) Dust alternatives there;)

Those settings can't be right...I encoded the same video, the first one using IVTC and the second leaving the video telecined, using those settings.

The playback on the second video is very jerky, but it's very smooth on the first.

Something is wrong.

Could be an incorrect field order.
