Jerked images upon buring DVD

[Ilovm]

Hi again,
I realzed I posted my question in the wrong group ...
Do it again...



Hi there,

IMAV user working with FCP7, DVDSP, Toast10

After compressing a FCP project with Compressor and burning DVDSP with DVDSP, I realized that scenes containing objects or people in rapid movement where showing jerked images.

The slow motion scenes are fine.

I checked the following

settings for DVDSP burning: VBR two pass;
averageBit rate 4,0,
max rate 7,0

1) the self-contained QT that I started with is not showing this problem.

2) the m2v file obtained from compressor (I use preset setting for high quality compression) does not show this problem when I view it with MPEG streamclip

3) I tried to burn directly the QT file with Toast 10 …get same problem if not worse !.
settings for Toast
automatic re-encoding
average rate 4,0 Mbps
max bit rate 8,0 Mbps
MPEG-2

I guess my problem comes from the bit rate I used ?

I am now confused and I am not sure I understood the impact of the bit rate setting on the quality of the resulting DVD, and I believe that using a high bit rate in DVDSP might result in problems for some clients to play the DVD on their player ?

Could it be something else ?
could someone please give me advice ?

Many thanks in advance
Ivan

How are you viewing the actual DVD? Have you tried another player ?

Was the original content interlaced or progressive ?

Describe what you mean by "jerked image"

Do you mean forward-back-forward-back ? - this would suggest wrong field order

Or do you mean choppy as in strobe like motion ? - this would suggest you deinterlaced it somewhere




An average bitrate of 4Mb/s and max bitrate of 8Mb/s will have no issues in any DVD player in terms of playback problems
