Film/NTSC/Video

Post by Zwill » Thu Nov 06, 2008 4:46 am

Well I got my dvds a few days ago and started to rip them. I'll show you what DGIndex gave me.

1.) Film 63%/Interlaced -- Field order Top
2.) NTSC/Interlaced -- Field order Top
3.) NTSC/Interlaced -- Field order Top
4.) Film 76%/Progressive -- No field order listed
5.) Film 64%/Interlaced -- Field order Bottom
6.) Film 79%/Interlaced -- No field order listed
7.) Film 61%/Progressive -- Field order Top
8.) Film 70%/Interlaced -- Field order Top
9.) NTSC/Interlaced -- No field order listed
10.) NTSC/Interlaced -- No field order listed
11.) NTSC/Interlaced -- No field order listed
12.) NTSC/Interlaced -- No field order listed
13.) NTSC/Interlaced -- No field order listed
14.) Video 96%/Interlaced -- No field order listed
15.) Video 93%/Interlaced -- Field order Top
16.) Video 94%/Interlaced -- No field order listed
17.) Video 92%/Interlaced -- No field order listed
18.) Video 95%/Interlaced -- Field order Top

This seems weird to me, l ripped the non credit OP and got these.

10.) NTSC/Interlacing -- No field order listed
11.) NTSC/Interlacing -- No field order listed
13.) NTSC/Interlacing -- No field order listed
14.) NTSC/Interlacing -- No field order listed


Look at the to bold dvd tracks, one says NTSC and one says video, what does video %'s mean? I've only dealt with NTSC sources so far so l don't know how to approach Film or video %. They were ripped per dvd as well.

NTSC encompasses both 29.97fps and 23.976fps video. Video commonly refers to 29.97, Film commonly refers to 23.976 (which in the context of DVD-compliant MPEG-2, requires pulldown). In DGIndex, Video and Film are simply measures of how close to having 3:2 pulldown the stream is, denoted by the %.

High video values are roughly comparable to normal NTSC, where the stream is either a pure 29.97fps and the interlacing is regular or where the telecining operation has been put directly into the video stream instead of flagged to do so on playback.

High film values mean that there are detectable pulldown flags or patterns. If the pulldown was done properly, then the value will more than likely be over 95% Film, possibly even closer to 98 or 99% (although on occasion you may get 100%, which is simply Film, similar to the plain NTSC designation).

If you find high (95% or above) film values, then in DGIndex, under Video->Field Operation, select 'Forced Film', and re-index the video. In your script, you'll need to omit the IVTC stuff - i.e. TFM and TDecimate.

Videovalues at any percentage can be treated just like normal, with TFM and TDecimate. Lower (under 95%) film values should also be treated this way, as the pulldown may be irregular or unpredictable, which could result in problems if Forced Film was used.
