Video on DVD get blured during motion

[joemammafats]

Hello,
Not sure if where this post belongs.
I am a newbe, Not a fan of tmpgenc programs. Have been using the latest nero with good success. Problem is that dvd produced from good mpg2 quality files will result in strange motion durring play back. If the scene has fast moting or sudden jumps that the play back video will blur. How can this be solved. Its nero that is doing it. same thing happens but worse if i use the arcsoft showbiz that came with my burner.

Do you import your mpeg straight to nero and then burn ?

[joemammafats]

Yes i do import mpg2 directy into nero

This has nothing to do with Nero but with whatever created the mpeg files in the first place. Blurred movement usually means too low a bitrate. Your good quality mpeg files obviously aren't as good as you thought. How are you creating them and with what settings?

Ive been having the same problem but I doubt that it is because of low bitrate.Ive been testing bitrates between 8000 and 9603.They all come out blured during fast motion and pans.

Are you capturing using VBR? Is your playback device progressive or interlaced?

Yes, Im using VBR and Im not real sure if my playback device is progressive or interlaced...I'll assume that its interlaced because my first dvd project didnt come out blured.

I see that you don't like TMPGENC, so I'll try to work around that. I had a similar problem that may or may not be related. When I burned my video to dvd the video was jittery and shakey. I found out that the original program that I rendered the video with was bad and that accounted for alot of the shakiness. I also found that the bitrate was actually too high. Lowering it fixed the problem. Something you can try to fix this is run your captured mpegs, (the pre-rendered video file) through a program like XMpeg with a CBR bitrate between 5500 and 3500. You could also use TMPGENC. If that works then you know its your encoder. To sidestep the issue of rendering with the encoder you are using, try to capture in the format that you want. Here's my process for doing this that includes all free programs that you can use as a reference if the encoder is really the problem:
1. Capture MPEG-2 CBR either 720x480 or 352x480 with DVXCEL (came with my capture device, but you can find something similar in the tools section)
2. Split the MPEG-2 file into m2v and mp2 using demux found at: http://www.geocities.com/ted_rossin/tools/Video/Video.html
2a. If your audio file that you get with demux isn't mp2, use BeSweet and BeSweet GUI to convert it.
3. Import your mp2 and m2v files into MPEG2Schnitt. Cut out the parts of the video that you don't want and export the new mpeg, doesn't require rendering.
4. Import your new mpegs into GUI for DVD Author, author your dvd and create your VIDEO_TS and AUDIO_TS files.
5. Use nero or your favorite burning software, import the VIDEO_TS and AUDIO_TS folders onto a data dvd and burn. That's it!

If the problem isn't resolved by bypassing your original encoder, let me know and I'll try suggesting something else. Good Luck!

Possibly an incorrect field order issue.

Possibly an incorrect field order issue.

I was thinking the same thing.

It happened to me only when someone was moving - it was like there was four outlines of their body or something. Changing the field order worked for me.

Every once in a while I'll use TMPGEnc to encode something instead of CCE and I always seem to forget to change that setting. For PC only video it's not a big deal, but you sure get a wake up call when you put it on DVD & pop it in the set top player.

That's probably the worst thing about field order problems - you play it on your PC and it's fine, yet on the DVD player it looks like everyone's doing Flash Gordon impersonations.

Is there anyway to determine what the field order should be??? I always use the upper.

[guns1inger]

If the source is DV (or was before encoding as mpeg-2) then the source will usually be lower field first.

[jimmalenko]

I think there was a guide somewhere here for a foolproof way to determine filed order ... unfortunately I'm a fool ...

[Prettysmile]

Video Studio 8 has a new feature where it can detect what the field order should be...It says my analog sorce should be lower field first.Although, the first part of the file comes out shaky, the overall quality is great.Just like the original.Hopefully, it will look that way when I burn it to DVD.

It does now look like the problem is my so called good quality mpegs. when i use nero to convert to dvd format the bad quality is passed on. I have no access to the source of these clips. so, i used nero with the highest bitrates I can. I found that at least its not getting worse as it was before i upped the bitrates level. I would love to re-render and fix the low quality mpegs before making it a dvd.

[thegeeman]

Change your bitrate from CBR to VBR. This a dual pass and allocates greater bitrate to scenes of increased action/motion than very still/ lifeless scenes. This MAY help-depends on quality of your source.
Suggest you set it up on batch encode BEFORE you go to bed!! It takes ages as it is a 2-pass process.
