Please point me in the right direction.

I am converting AVI movies to SVCD and then Muxing them with DVD-Lab.

I am using the PAL standard.

The trouble is ,after stripping the Audio to AC3 and then encoding the Video from AVI to SVCD, having compiled the DVD using DVD-Lab some films are "Pixelating".
Please note that i check for "Video Freezes before using TMPGenc.

I currently use 720x576 as the target resolution. Is this resolution too high for the video i am converting.

Could someone please recommend the resolution to use when converting SVCD to DVD-r.

Thanks in advance.

If you have avi movies why are you converting to SVCD and then to DVD? Why not just go from avi to DVD? Pixelation is usually caused by too much compression (too low a bitrate). Look at the "What is DVDR" at the top left to see what framesizes/bitrates you should be using.

Trouble is i want Multiple Movies on each DVD-r.

Not one movie on One DVD-r disc.

Thanks for the reply

Seriously, there seems to be no point in going to SVCD first. You are shrinking the movie so much that it WILL pixelate. DVDs are cheap - put one movie per DVD, or one movie per SVCD.

Could you please recommend a tutorial link for going AVI to DVD-r please as its hard to know which is the best!!!

Also using the "Lossy" principle it seems hard to see how going from 700Mb AVI to 4.3Gb DVD-r will offer any benefit.

Surely because of the "Lossy" principle going to 2Gb and having 2 movies on a DVD-r seems more logical.

Please don't flame me if i'm wide of the mark as i am quite new to DVD-r technology.

Any advice is most appreciated.

You could go to a smaller frame size and lower (VBR) bitrate to get more onto a single DVD. Depending on your source & hardware, the difference in quality from your full res frame size and a half D1 frame size should be fairly negligible with analog captured source.

I have managed to get 2 movies on a DVD-r with possibly room for a 3rd.

The Average Bitrate was set at 2000 and resolution of 720x576 PAL using TMPGenc.

Trouble is some AVIs look great but some show pixelation.

I was wondering what Resolution is SHOULD be using etc.

I'm not sure I understand... if you have a 700 MB AVI, you can use a number of DVD authoring solutions to put more than one movie (of THAT size) on the disc. But if you shrunk a 4 GB MPEG2 movie down to get a 700 MB AVI and now want to burn that onto a DVD, you will not regain the quality you lost going from MPEG2 to AVI and will be stuck with gross pixelization.

The problem is that SVCD uses a much smaller screen size to convey information to the screen, and doesn't need as much information in the file. When you go from SVCD to MPEG2 you are more than doubling (tripling or more?) the screen size without increasing the video information, and you end up with huge pixels.

I use Vegas Video, so I can't help you with the freeware stuff on here, and I don't have a solution for what you want to do. As cheap as CDs and DVDs are, I don't see the point. Good luck.

Could someone please explain this:

Me thinks....

AVI source = 700Mb
SVCD Converted = 1.5Gb+


How can this be shrinking the movie!!!!

As before please excuse my ignorance i am fairly new to this subject.

"AVI source = 700Mb"

Is the AVI MPEG-4 with VBR audio?Use AVICodec to check.I agree with the others,why are you converting to SVCD?Just import the AVI(you might have to convert the audio to WAV first) in TMPGEnc and use the DVD template.

I currently use 720x576 as the target resolution.

Try trimming off a small sample clip (20-30 seconds or so) and resizing to a target frame size of 352x576, and encode your test clip with the same bitrate you were getting pixelated results with. If it looks okay then figure the total length of all the clips you want on your DVD and use a bit rate calculator to get your bitrate. Then double check your results using that bit rate and smaller frame size on your sample clip.

Please read earlier post..

I want to put 2 or more movies an each DVD-r.

The Average Bitrate was set at 2000 and resolution of 720x576 PAL using TMPGenc.

A resolution of 352x576 encoded using VBR at an average bitrate of 2000 will look good, at 720x576 it will look bad. Convert your avi to 352x576 (which is valid for DVD) and everything should be OK. Simple solution.

Jako, I have a suggestion, but only IF your DVD Player works this way. IF your DVD player plays XSVCDs, then here's what you do. It also works with Xvid as well.

Open TMPGEnc, and convert it to 480x576, the proper PAL frames per second, but don't convert the audio. It should take about 62 minutes per every 1 hour of DivX you convert. Set the bitrate to "Manual VBR", or MVBR, and set the maximum bitrate to 2520, and the minimum bitrate to 1000. Your results will be phenominal. But you will only be able to fit about 3 hours on one disc. (Each 1 hour of converted Mpeg should be about 1.1 gb, so you MIGHT be able to squeeze in 4 hours per disc.)

Now, IF YOU HAVE IT, open up Adobe Audition. File -> Extract Audio from Video, select your source file, and let audition open the file. ONCE it opens the file, DONT TOUCH IT, 9 times out of 10, the audio is already 48kHz, so you don't have to do anything to it. Just click on File -> Save As, and save it as a Windows PCM wav file. Let Audition save it.

Now, open up TMPGEnc again, and select ES audio, and set the bitrate (Preferable 320 kbit), and now convert the audio to *.mp2.

After that's done, in TMPGEnc, click on File -> MPEG Tools. Now go to the "Multiplex" tab. Add your *.m2v file, and your *.mp2 file, and multiplex, just to see if everything is in sync.

If it is, go to DVD-lab, and import your newly created MPG file into the assetts, and select "Quick mode without demultiplexing". Now, create your chapters, author your DVD, Enjoy.

Jako, I have a suggestion, but only IF your DVD Player works this way. IF your DVD player plays XSVCDs, then

Why use a non-standard format? If you use 352x576 it will look almost as good and every DVD player will play it.

[JakoUK]

Thankyou all for your guidance.

And yes as previously mentioned i ALWAYS check for bad frames.

I'll try the the 352x576 resolution.
