authored DVD picture stutter

[efiste2]

:( please can anyone help me out, i have authuored a dvd using the following

captured with canopus advc100
converted using tmpgenc plus
authoured using tmpgenc authuor
burned the created TS video file

BUT the finished articel jumps/stutters like a strobe effect on the parts of the picture that move when i play it on my DVD player, I know that the media usually works fine in the same player too, im new to this game so any advice would be most welcome!!!!!;)

Did you try checking the encoding file to make sure it didn't happen on the encoding? If it is, you might want to try reencoding it again.

Sounds like you have the wrong field precedence (i.e. instead of field order 1-2-3-4, you have field order 2-1-4-3).

You should be able to use pulldown.exe to change the field order without re-encoding. Can't remember the options - something like

pulldown -nopulldown -tff odd movie.m2v movieFixed.m2v


You'll have to check pulldown help to find the correct option names and settings. Just type pulldown with nothing after it in a command prompt window; that usually displays help. You also might need to try both field orders to find which one is the right one.

many thanks for replying to this problem, dont know if it makes a difference but the authoured disc plays fine on my PC, :confused:

OOOH, I remember this exact thing happening. On an anime cartoon, it plays perfect on WinDVD, but when I burnt it the video twitched.

Try out this thread for size. :)

That's one of the problems with previewing interlaced material on a PC - you aren't able to see field order problems.

PC displays are progressive, so the fields are combined then displayed together. In other words, you see fields 1 and 2 at exactly the same time, so instead of seeing 1-2-3-4-5-6 (as you do on a TV), you see 12-34-56. Because they are combined together in the time domain, 21-43-65 looks exactly the same as 12-34-56 on a PC display, and you can't see any stutter.

It's a shame no one has come up with a double-rate MPG player. If the PC would display n2-21-14-43-36-65-5n (where n is a null field), we'd be able to see field order problems. The monitor refresh rate in most cases is certainly high enough (greater than 60 Hz) to support this.
