jerky motion on DVD

I have just assembled wedding video in Premier Pro exported it as an Meg2 DVD timeline, run it through Encore on default settings and the finished footage is noticeably jerky, I had read on the forum that I should be using a 2 pass setting and I also moved the maximum bit rate from a standard 7 to 9 which I have never done before. I have always had the settings just as Pal widescreen high quaility, I have to say the quaitity of the Dvd is excelent if I could only get rid of the jerky movement.

As a test I encoded again with just a 2 pass setting but still the same jerky motion, I then encoded once more but this time to F4V 720 source half size flash 9,0 r115 and higher. that runs perfectly on my PC so I guess the fault is with the Mpeg2 setting im using, I could use one pass but now I have seen the good stuff I want to try and produce it.

I do record on my Sony FX1 at HDV and download via ilnk.
Regards Nigel

Re: jerky motion on DVD

Sounds like there is a field order mismatch - your m4v is progressive, hence no field order, no jerky stuff.

The FX1 shoots HDV, which is upper field first, while DVD is lower field first.

Re: jerky motion on DVD

First make sure your original sequence in Premiere is at the correct settings for your HDV video. If it's set wrong then like Nigel said, you make be getting a field order mismatch. That is what it sounds like. Premiere should recognize the video and adjust to proper mpeg2 DVD, but if the sequence is wrong, I've see it mess up when having to render twice. Second depending on what version of Premiere you are using, I would do a dynamic link to Encore. Let Encore do the encoding to mpeg 2. If you are giving Encore mpeg 2 it might be re-encoding it again. It's most likely just a small setting that is off.

Re: jerky motion on DVD

Hi Nigel,

Where is the footage jerky? If on your computer screen, this is normal because PC displays are progressive, so interlaced footage typically does not look good. Have you actually burned a DVD and previewed it on a regular TV display? This is the best way to test.
