VOD choppy

[torgosPizza]

Yeah, but I want to download the mpeg again as much as Torgos wants to retransfer it. Especially after I already burned my own DVD with the choppy version before doing a full viewing.

What kind of player are you watching this on? Do you notice it on your PC as well as your set-top box?

[MSTJedi]

It's definitely still there on the DVD I made from the mpeg. It's not a deal breaker on such a crappily shot film anyway, but it's noticeable.

[torgosPizza]

Yeah I am watching it on my home BD payer. It's noticeable in some spots and not others... which means that it changes throughout. Although it does look like some kind of frame aspect pulldown could be performed on it... I'll let you know next week.

[Pak-Man]

Same choppiness on my download to burn. Tolerable, but occasionally noticable.

[TheUnabeefer]

Got a bit of choppy here too, but nothing to detract from the awesome riff.  I've seen much worse on better movies, so I don't mind much.

Kinda reminds me of those intros from movies like Pod People and Overdrawn At The Memory Bank.

[The choppiness is] noticeable in some spots and not others...

That's exactly what I saw on my DVD created from the mpeg.

Wow! So the Download to Burn' version was a better choice afterall, it seems..

Uhm.. except for the people who got the VOD versions like DivX that didn't have any stuttering.

Well, except those don't get burnt to DVD (as far as I know).

[Action Batch]

Well they can. The problem is that the divx or wmv versions are lower quality. The one you'd want to burn to DVD would be the mpg. Honestly the choppiness doesn't bug me. The whole movie, from a technical standpoint is garbage so it's of little consequence.

I was wondering about the source audio and MKB.mp3s though.

[Piobman]

Yup choppy with the mp4 file for me too. I'm reauthoring mine with the official DVD so no biggie... but normally when video turns out like that its because when encoding the wrong Field is chosen during encoded for the frames. I haven't tested this theory, but its an easy fix (no re-encoding needed) if that is in fact the problem.

But if it's a problem with the encoding, how can you fix it without re-encoding? When we do a 3:2 pulldown that's usually what has to be done. Okay maybe it's not a 100% true re-encode, maybe that's what you're thinking of? Either way it's still not an instant fix. =/

Okay... I looked a bit closer at the video file and I see what you mean. It definitely is 3:2 pulldown like you said which explains why there is judder. I was thinking it was just flagged wrong... which would be fixable even after the fact. But telecine judder is a whole other ball of wax as you mentioned, re-encoding would probably be in order to fix it. I wonder, why use 3:2 pulldown? I was always under the assumption it was mostly used to covert film to ntsc. If the original source is in fact 29.97 would it not be better to just encode without 3:2 pulldown? I'm not real familiar with all the reasons one would need to use telecine... but I've never found much reason to use it other than for going between frame rates. You got me wondering about this now. Oh, the horrors of video framerates!

[torgosPizza]

Yeah, that's the main problem. I'm not the 100% tech guy to ask about this but from what I know it can be affected when ripping and re-encoding, or even pulling the mpeg-2 source off a DVD. Different sections can be encoded with one field going first, and then they switch later on. When that happens you have to telecine each cut individually, which obviously takes more time.

Anyway now that everyone is back from vacation i'll find out how feasible it is. If it were up to me I'd do it anyway, assuming we have time. Thats the main issue right now, I think. But I'll find out either way.
