29.970fps Interlaced source please help
I have an mpeg2 encoded video with 29.970fps and interlaced frames.
My problem is that not all frames are interlaced. When i use vdubmod's deinterlace filter it will be applied to all frames. It will reduce the resolution of progressive ones. I want to get this: 29.970fps some frames interlaced >> 25.000fps non interlaced video I'd like to use Avisynth and it's filters, but i dont no witch filter to use, and what settings. I'am a beginner with encoding, please help. If this thread has been answered somewhere please insert a link to it. And sorry for my bad english. |

Depending on what deinterlace filter you are using, progressive frames won't be degraded.
The other task, such as converting framerate from 29,970 to 25 requires an avisynth script and can't be done with Vdubmod ( at least as good as Avisynth does) Search for 30p to 25p or something like that inside this forum. Also look at avisynth.org |

Thank you for your reply.
I heard about telecine, decimate filters, they can remove duplicated frames, since this is a TV source video, can i use them to 29.970fps>25fps deint conversion? If i make such conversion how can i sync the audio to 25fps? |

you donīt need to resync the audio if you are doing a framerate conversion, unless you want to speed up or slow down your video.
If your source is from real video telecine has nothing to be with that.It is meant for restoring film to video original framerate. You could use decimate but the output would look jerky. What is your source exactly? Please tell us very very clear where you are now and where you want to go.. |

I would say go for Decomb (an avisynth filter) since it's so well documented and tested, and can be made to take care of certain telecine problems if needed through the use of manual overrides.
That would get you to 23.976, and then you could just use an avisynth function like ConvertFPS. You could also check out RePAL. I'm an NTSC guy (here in R1 land) so that's about all I can say until I get some more PAL sources to work with. /me goes back to waiting for a remastered boxset of NGE to fall out of the sky

actually, one question i have that is a little OT: how many on this forum have TVs capable of displaying NTSC and PAL? i know mine does, so i needn't worry about format conversion so much. a lot of r4 titles don't get converted at all and are left in NTSC (which i appreciate greatly for TV series shot in that format.)

really weird:
my 12 years old JVC-TV can't even handle PAL-60 but my parents even older (17 years) robotron-TV (made in GDR [German Democratic Republic, not to confuse with FRG]) is able to handle PAL-60! hehe

My bedroom TV (a decent 27" RCA) is maybe 4 years old and doesn't care what you feed it as long as you don't use the S-Video port. I suspect that has something to do with my cousin attempting to shove an RCA plug or RF adapter through it several times though.
The Panasonic in my livingroom is a whole different story. It's a bigoted TV if their ever was such a thing. It doesn't even like NTSC-M let alone anything PAL. You'd think it would at least display all formats prefixed by NTSC eh?

heh. this should really be split into a poll thread...
i didn't realise multi-format teevs were so uncommon. i suppose mine's new (my 25+ year old National finally exploded for the last time 2 years ago) but it's not terribly expensive.

im an aussie in pal-land and all new tvs that i know of (probably to around 3 years) support ntsc... but wait!
didnt the mario bros. have a question? you said that some frames are interlaced and some are not, but it was from a tv source? is this film content taped off your tv? if so, then you code should be this: mpeg2source ("xxxxxxxx.d2v") doubleweave pulldown (0, 3) # play with these numbers to get the right results assumefps (25, true) that will get you the proper frames. if youre doing a full blown ntsc-pal conversion for film, then also add this. bilinearresize (720, 576) resampleaudio (48000) # or whatever frequency
