I do both. I look at the video as it comes out of the decoder (woven fields) and also with a Bob().
I think the 32ms audio delay granularity restriction is only with VOB.
I do both. I look at the video as it comes out of the decoder (woven fields) and also with a Bob().It doesn't hurt to always bob it or separate the fields, but I usually just open the unfiltered video to check it. If there's anything peculiar about it, I'll put on a Yadif(Mode=1) to have a further look.
And is it because it's progressive the frames looks unfocused? because someone already did a bad conversion? this video looks way worse compare to the other.
Thank you again
Exactly the same thing.
Someone resized this video vertically with SeparateFields().WhateverResize().Weave()
So I'm done with the NTSC DVDs, and has PAL now. Black bars at the video I shared, suggest this is NTSC converting to PAL. Also, quick google showed is an Anime from Japan, which is NTSC-J. Because it's NTSC the end-results should be 23.976? What about "Real" PAL cartoon (that wasn't converted). It should be 25?
I assumed NTSC converted to Pal is more complex to work with. I was able to pick steady frame movement to know what the pull down is. I tried normal TDecimate, and It ends with 20FPS. So I guess it isn't good. I used SRestore(frate=23.976), and while panned shots move at 1 frame per movement - some sections has blended frames. So is there nothing better to do except using SRestore here?
What about real PAL Cartoon? can I use TDcimate on it?
Thank you jagabo
That PAL video is a little unusual -- it has partial field blending. If you look at individual fields you'll see some of them are clean but some have blending on only a part of the frame. This seems to work pretty well:
Mpeg2Source("Pal.demuxed.d2v"Info=3) Blur(0.0, 0.15) QTGMC(Preset="fast") SRestore(frate=25)
Thank you jagabo
So, I'm familiar with most of the code. I didn't know the Blue() command, and now you mention it, I indeed see the ghosting effect you mentioned.
So answering myself by reading between the lines. It seems that even though the PAL video is NTSC converted into Pal, the final Frame rate should be indeed 25 and not 23.297. I also assume the true PAL videos should also be 25.
Does it means I always need to use SRestore? or TDecimate(mode=2, rate=25) can work too?
EDIT: Oh no. Seems like TDeimate want the new rate to lower then the current one. How can on TDecimate PAL?

Of course, the other option with field blended videos is simply to QTGMC them. It won't look any worse than playing the original DVD -- usually a little better since QTGMC is better than other deinterlacers (ie, the ones built into TVs, DVD players, graphics cards, software players, etc.).
In this particular case 23.976 left many jerks from missing film frames. 25 worked better. I also tried 24.975 and 24.
TDecimate() preferentially removes duplicate frames. It will see blended frames as unique.

By default TDecimate() removes one of every fiver frames to go from 29.97 fps to 23.976 fps. But it can be used to remove M of every N frames with TDecimate(Cycle=N, CycleR=M).
I'm running old DVD/VHS Captures into DVD now. But what will happen with modern animation. Computer generated animation for example, or Disney movies converted into DVD. where all is progressive and there is no repeats. If there's one movement per frame I should basically just convert it into mp4 without modifying it?
I had a chance for example to see an cartoons in 4:3 size, but it had big bottom/upper black bars like it's kinda wide screen. Can I just crop those and set SAR to be 16:15 (PAL)?
And that will give you 24.975fps. If starting with a PAL DVD made from an film master (and isn't field-blended) then:
That will result in 24fps.
Excuse me for being slow here, when I'm saying "Starting with 25FPS DVD". I mean a DVD from PAL Region. The Vob has 25FPS. I have seen couple of varieties so far:
- NTSC DVD, 2:3/3:2 pull down, Just TDecimate.
- NTSC DVD from PAL master (which isn't field blended). I used Cycle=6,CycleR=1.
- The 25th frame is duplicated. solved with Cycle=25,CycleR=1 as you mentioned above. Is that a standard PAL Cartoon?
- No frame is being duplicated (I tested around 50 in a row). Does this means in a True progressive and there nothing I need to do with it?
I have a single video that neither TDeimate or even SRestore were able to remove the blended frames. In a videos I can't find a pattern in frame movement, I mostly go to pan section, try couple - and see if the panning is smooth afterwards and doesn't jump an extra frame.
