video jittery and sound keeps breaking up
video jittery and sound keeps breaking up –
Ive tried using SMS V 1.6 rev 5 and 6 and I get the same problem playing some episodes. Im currently watching Eyeshield 21, and well, the first 6 episodes played fine on SMS, but from episode 7 and on the files dont play properly, the video freezes for a little while and the audio breaks up as a result of this, I was wondering if anyone knows what the problem is. The encoding is no different than the previous episodes and the resolution is the same as well.
I dont know what could be the problem, can anyone help?
audio format: mp3 variable bitrate
QPEL or GMC? check with GSpot.
I'm also curious about the video and audio bitrates.
I dont know what QPEL or GMC is but Ive taken screenshots of the two episodes, the one that works and the one that doesnt. The only difference I was able to catch in GSPOT was that it was able to detect the average video bitrate for the one that doesnt work, and wasnt able to detect the average vid bitrate for the one that does.
here are the screenshots
hope someone can help,
I should have mentioned that the latest versions of GSpot are required (still in beta).
A QPEL or GMC indicator will show up under the -Video- Stat: area
It is strange that the working video doesn't have the bitrate displayed. Another thing you'll notice is that the working video was made with AVI-Mux GUI, and the second with VirtualDubMod. This is reflected by a difference in the audio interleaving, and it may be easily correctable (if it is the problem). Simply open your AVI in VirtualDub, select direct stream copy for both video and audio, and Save as. It should only take a couple minutes and has a decent chance of correcting your problem.

okay used the new gspot and found out the one not working properly uses QPEL and Im guessing SMS has trouble playing QPEL encoded files, so any suggestions how I can fix this?
QPEL is processor intensive. You'll probably have to re-encode the video (without QPEL enabled). This can take a while and will decrease quality (but may not be noticable).
If you feel like experimenting, and have an optical sound system, you may be able to squeeze a bit more performance out othe PS2. Re-encode the audio as AC3 (Dolby Digital) and leave the video as it is. Then enable S/PDIF optical output in the SMS Player settings. This should free up some CPU cycles for video decoding. I'm not sure how much extra QPEL performance this will give you as I haven't tested it yet myself. Given your video resolution, I'd be surprised if it made enough of a difference. But I think those are your options.
okay, ive figured it out. looked around on the internet. I just have to reencode the eps, I did one and it worked like a charm. good thing the encoders didnt do the QPEL thing for all the eps or else I wouldve had to reencode all of the eps.
the reduce in quality is barely noticeale so it's all good.
Thanks hunter for the help.
hmmz, farisr: did you play them from dvd? Cause I have some DBZ episodes on dvd, and some of them show the same errors like you described. I always thought that those were from some errors in the dvd when I burned them.
Maybe I should check those eps and see if I can fix them like you did with yours. But as far as I know there all the same way encoded, but you never know
sorry for the late reply ya i did play them from dvd, but it wasnt the way it was burned onto the dvd it was the encoding of the video itself.
