please, jerky footage at DVinfo.net

Richard Grebby · August 25th, 2009, 11:05 AM

I just cant understand why I cant get footage to play smoothly.

Ive been trying this none stop, every way i can think now for 3 days as it must be dine by tomorrow.

Here is the problem,

I have a old dvd with archive footage, I need to take that footage and move it to a new DVD with menus on it etc.
The main feature works fine, although Ive had to use a rip sound and the renamed vob files.

The special features part of the DVD contains new footage which is on another disk. I did the same method, move the vob files over, renamed them and used some ripped sound that i managed to get when I first tried to convert them to .mov

Anyway, I render out of premiere to mpeg-2 pal dvd and goto encore. With the footage on a timeline I can use the monitor to see its nice and smooth.

When I burn to an ISO and check the footage is very jumpy and jerky. However its not all the footage. the main feature works fine, most of the seprate news files work fine, just the odd one or two of the news files are jumpy and unwatchable.

I have burn a disk and tried it on lots of dvd players but its all the same.

Can someone please help as im going mad.

Are you using proper bitrates during the rendering/encoding process? Most DVD players that I've dealt with over time have trouble playing back smooth video at bitrates higher than 7.5MBPS. Try using a lower bitrate and see if that helps. Also, what speed are you burning your disc at? I've found that while several kinds of DVDs are rated for burn speeds up to 16X, I always run into choppy video if I burn a disc at those speeds. Another thing you might want to try is burning a disc at 1X, 2X, or 4X and see if that resolves your problem. Hope this helps!

It might be that you need to "render" the jerky footage . . . are you getting a red line?

It sounds like you've put a setting wrong somewhere. Pay close attention to the bit rates. As Shawn said, some players don't like high bit rates. I wouldn't dump your existing workflow just yet. If it works for the old footage, it should work for the new stuff too.

You might also want to try the disk on different players to see if it acts differently.
