Quick question about progressive/interlaced encoding

Advertising


MessageAuthor

Hi! I have a doubt. I am not sure about some encoding options. I have a PAL 4/3 film. At the beginning I've encoded this film in Interlaced mode, Top Field and Alternate Scanning Order. The output is Ok, no jerky video (so fields are correct). With VirtualDub MOD I've opened the source (for curiosity) and i've seen that the video doesn't have the "interlaced" lines (the scanlines). So to be sure I've made 2 AviSynth scripts... one with AssumeTFF and one with AssumeBFF. Both scripts gave me same results (no jerky video in both scripts) so I'm assuming this is a full progressive 4/3 movie. Can this be true? Can i encode this video with Progressive Frame flag and ZigZag scanning order in CCE? Thanks!

RE: Quick question about progressive/interlaced encoding

I ran into this the other day with a source called 'GoodFences'. DG told me it was 'hard telecined'. This sounds similar to your situation. Open your most simple avs in VDub. Find a spot of movement and step through frame by frame. Do you see 3 'clear' frames and then 2 'combed' frames? You will know for sure. If so, try using decomb by adding this to the bottom of your script. The docs have much more info and are worth a read just from an educational standpoint. Telecide(order=1,guide=1) Decimate() If the resulting output plays to your likeing in WMP or VDub, run pulldown on the output before muxing. pulldown.exe yourvid.m2v outvid.m2v -prog_frames p Now you will have a progressive stream flagged as 29.97

DDog, mp3dom is using PAL. thus no decimate is needed (in MOST cases). Further no NTSC-complications needed here :)

RE: Quick question about progressive/interlaced encoding

Thanks for the replies! So... about CCE settings... Can I encode the film with progressive parameters? Thanks again.

RE: Quick question about progressive/interlaced encoding

simple equation: if (combing visible == true) then encode interlaced else encode progressive easy isn't it?

RE: Quick question about progressive/interlaced encoding

mp3dom, Be carefull with software DVD players: using them, you usually won't notice if you've choosen the correct TFF/BFF parameter. Better burn the movie on a rewritable, and test it on a standalone player first. But that is for interlaced encoding only, or course :-) If you encode as progressive (as you should do according to what you say about source your video), then there is no problem with the field order. However, is your original DVD video flagged as interlaced? It often happens with PAL DVDs that a progressive source was encoded as interlaced, and so you can't see any combing effect. In that case, don't forget to use ConvertToYUY2(Interlaced=true) in your AVS script to get the proper colors. You may already know all this, but it doesn't hurt if I repeat that :-) Strange thing of the week: I found a DVD that holds video flagged as interlaced (however, no combing effect is visible), but scanning order is set to ZIGZAG. An alanysis of the whole video revealed that 100% of it is like that. It's the first time I see that.

RE: Quick question about progressive/interlaced encoding

For mixed content, of course use the "most compatible" setting, that is, interlaced coding and alternate scan.
