Jerky playback in stand alone player as a result of burn

[burgkev]

I am growing tired of trying to correct the prob of jerky playback on some AVIs after burning. Through research and trial and error, I found that AVIs that play fine on media player but jerky on stand alones, there were no codec probs (ran through Gspot), but had to increase the framerate to NCTS standards. Don't know of any software that does this for AVIs w/out converting it to DVD. So, I said screw it, I'll convert it to DVD in TMPGenc so I can adjust the rate. The end result was smooth playback but no audio!
Any suggestions? I don't want to be confined to watching video files on my computer.

Thanks in advance,
Kevin

So you have a dvd divx player ? and it doesn't like pal avis? or what is the framerate of the video that doesn't work fine ? Or are you converting to DVD?

You can change the avi fps without any conversion of the video using virtualdub but you must change the audio speed to get it synced.

The standalone plays divx, and apparently it doesn't like PAL. The framerate of the AVI is 25.00. I would love to keep it as an AVI so I can build a data DVD. You say virtualdub can help?

EDIT: I see. You are needing to do a framerate change. That would explain the jerkiness. You can use VD or VD Mod to adjust the framerate.

With TMPGEnc, what type of audio did you input to it? Gspot should have told you if it was MP3 VBR or AC3. TMPGEnc has problems with those formats. If it was AC3, just add it in with the encoded MPEG when you author it. If it's VBR, save it out as a WAV audio with VirtualDub Mod (Full Processing) and use that for your encoder audio input.

And welcome to our forums.

The avi is Xvid, and the audio is AC3. Sorry to ask, I'm a novice, but how do I "add it in the encoded MPEG" when I author?

I have reason to believe alot of your problem is the authoring/burning software you're using. Usually this type of software, Nero for example, does great work with menus, and the final burning on the disc, but can really suck in the encoding beforehand from DivX/Xvid to MPEG-2 compliancy. NeroVision is a perfect example of this (if you're using it).

When you said you used TMPGEnc and got good (video) results, it's obviously not your software or your burner physically.

Ok, having said that, and you would still like to make "traditional" DVDs without a DivX Certified player, you might want to get TMPGEnc Xpress. It's a bit more commercial, but is great at giving a final result with the video and audio streamed together so you don't have to do it yourself.

Furthermore, if you really want to avoid all that encoding/muxing/demuxing headache and just want nice DVDs, and don't mind paying a few bucks, get Ulead VideoStudio.

It's not the best encoder ever made, but with the naked eye you wouldn't know it. It will take almost any video (with codec), any region (PAL or NTSC), any audio, any size, resolution, etc. and transform it beautifully into an MPEG-2 DVD compliant file very quickly, painlessly and with beautiful results.

You can then load these files into your regular burning software and finish the job.

I can tell you're the type of guy that may appreciate a simpler solution. I think you can try the UVS from their site for free, and you will find buying it not expensive and worth every penny.

Sorry, I've been jumping back and forth between other threads.

I use TMPGEnc DVD Author and it will accept elemental streams, in other words separate audio and video files. With a Xvid that has AC3 audio, you don't need to do any conversions if it is DVD compliant to start with. You just demux it from the video. You can do this with TMPGEnc encoder or even VirtualDub or VD Mod. Then you encode just the video in TMPGEnc. When you author, you select your encoded video, and the AC3 you demuxed from the original file.

But changing the framerate from PAL to NTSC is a whole other problem. You need to make your 25 frames per second into the NTSC standard of 29.70 or 23.97 fps. And if you do that, the sound will be the wrong length.

But if you want an easier way, try ConvertXToDVD. It can handle the framerate change and the Xvid to MPEG conversion fairly well. The other way with TMPGEnc will take some time and effort to get the same results, unless you just want to do it for a learning exercise.

You can convert the XVID PAL to a XVID NTSC, but you will still have to change the audio to fit the new video length or it will be out of sync.

Oh, and as an additional note on a seperate message, Ulead VideoStudio also creates STUNNING DivX/Xvid video.

So if you just want files to burn as data, and not the "traditional" DVD type, then re-encode all your DivX/Xvid through UVS and burn it as data.

Sometimes when I get an AVI from another source, it won't play on my DivX Certified stand-alone, but when I re-encode it through UVS, it works so well.

Thanks so much Redwudz, and PUzZLeR, I will try that software, because you're right, I'm a little impatient with all of the converting.

Appreciate the help!
