Fade outs cutting off
-
6 frames is too few…it should be at least 15.
-
ok, would that make the ends not cut off anymore?
-
Perhaps. What I can tell you positively is that an I-frame every 6 frames is out of DVD spec and may cause playback issues such as what you are reporting. 15 frames is the minimum for NTSC- 18 frames is the maximum.

Ok, I’m trying to re-render out of AE directly as Mpeg 2-DVD. in the GOP settings there are N frames and M frames. Right now, by default they are 3 and 15, respectively. Is this correct?
-
I just re-rendered everything using these settings out of AE:
format: MPEG2-DVD
format options:
preset:NTSC DV 4×3 High Quality 7Mb CBR 1 Pass
video codec: MainConcept MPEG Video
quality: 5.0
TV standard: NTSC
frame rate: 29.97 drop frame
field order: lower
PAR: standard
bitrate encoding: CBR
bitrate (Mbps): 7.0
GOP settings:
M frames: 3
N frames: 15
audio format: PCM
multiplexing: noneThe video came out VERY jittery in most places. The audio was fine. The fade-outs had the same problem as before- cutting off when returning to the main menu.
The videos from before (6 I frames) looked much better (no jitter) than these.
Do you have any suggestions about format option settings in AE, or something in Encore to eliminate jitter, and stop the cutting off?
Maybe if I added a chapter point at the very end of the timelines in encore?By the way, THANK YOU for being so helpful!!

What’s the source of the original video? Is it DV footage, or something else?
-
I have no idea why the fades are bailing out early. Maybe check that the audio files are the same length as the video.
But I believe that a GOP of 6, while maybe unusual, is not out of the DVD spec. Most of the lower cost encoders default to a length of 15, but the higher end encoders will let you set other parameters.
Have fun!

Whoops, Rob is right. 15 frames for a GOP is common, but no required by the DVD spec. 18 frames is definitely the limit for NTSC, according to the DVD spec. Sorry about that red herring…or half-herring. 😉

Actually, there is good news: it might be just that tv.
My boss went home and tried it on one of his tvs, and he said the fades were beautiful. It seems that DVDs burned from encore are tricky in many ways:
The same disc that worked fine in tv a at work, wouldn’t even read in another tv at work. It had a lot of trouble loading in my tv at home, and eventually sort of crashed my DVD player and I had to unplug it, replug it.
In the tv at my boss’s house the vignette completely blew out the center of the image (way too bright), and the looping video/audio I had on the main menu didn’t loop at all, but stopped inbetween for a few seconds. Both of these were non-issues in the tv at work that read it.
Also, I cannot get the DVD duplication machine we have at work to even read it. We use this machine to duplicate all our DVDs, and I happen to know that a different DVD that was made with encore duplicates fine on it. -
Ooh..this sounds like either poor quality media, too high burner speed, or a burner problem. My guess is one of the first two. Which brand of DVD media are you using, and what type (DVD-R or DVD+R), and at what speed are you burning it?
