Jerkly Playback on Standalone (29.97 Interlaced Sources)

[mguru]

I noticed this issue was closed in known issues, and I have only run acrossed it (that I know of) with the latest build 1.10.7 with two of my newest additions for my WWI collection...a documentary and The Lost Battallion.

Both were unedited sources using EclPro through CCESP25. The final product plays fine on WinDVD, but when burnt to a DVD-R and played in my Sony and Pioneer DVD players, it is jerky and skips back frames (especially with pans and heavy motion). Almost like doing a bad IVTC pulldown in the TMPGEnc days. Both the source and final products are 29.97 Interlaced NTSC. I even tried burning to a RW and a second DVD to make sure it wasn't an disc problem.

I figure the frame rate or interlace are either not being correctly detected, or there is a problem in the re-encode.

Thanks for your attention to this issues.

Sounds like the source is BFF but is being played back at TFF (or vice-versa).

That sounds very plausible. Is there any way to control or correct this through DVD-RB, or is the only solution to do a manual conversion without DVD-RB?

DVD-RB should handle that situation automatically. Here's how it should have handled it (assuming the source was BFF):

1. CCE 2.50 can't create a BFF stream, so it needs to adjust.

2. The way it does that is by setting a value:

offset_line=1

This tells CCE 2.50 to shift the stream up one line (switching field order)

3. It then it tells it to output a TFF (top field first) stream. by adding this line:

top_first=1

Check your ECL file and see if this is set for the segments that cause the problem.
