Jerky Playback--Interlacing or bitrate?

[Insaniac]

This Question leans more to the DVD side of things rather than, SVCD, but it is regarding CCE.

I used the Premiere plug-in CCE SP 2.62 to encode 30 minutes of AVI(Captured from a Pinnacle DC-30) I used a 3-pass VBR with the average bitrate set at 6mbps.

When burned onto a disc and played in a standard DVD player, the video is jerky during motion(Camera pans, and character movement). My question is, Should I raise the bitrate(DVD can handle up to 9mbps)or could the problem be related to the source footage being interlaced? How can this be fixed? I'm perplexed, and still very new at this. Any help would be appreciated!

Hi Insaniac,

are you burning a SVCD on a CD-R(W) with an average bitrate of 6mbps? - I hope not. This is a far too high bitrate as SVCD standard only allows a max of about 2722kbps (video+audio)! So jerky playback can caused by this high bitrate because only a few DVD standalones can handle this bitrate of your created X(S)VCD and in addition if you are using interlaced material from a camcorder it is mostly in bottom-field-first order so you can't use the "Upper field first" setting with CCE which also causes jerky playback.

So try to lower the bitrates and/or try to unselect the "Upper field first" setting in CCE.

Thanks for the reply. Sorry I didn't specify, It is a DVD, and not a VCD that i'm creating.

I've discovered that the video plays beautifully smooth on my computer (With PowerDVD)and it's only Jerky from a set-top. That leads me to believe that it is a problem with the Field Order and/or the interlacing, and NOT the bitrate. I'm going to experiment with trying to reverse the field order, and deinterlacing the source footage.

I'll post my findings so hopefully this thread will be able to help people in the same boat as me!

Thanks!
