DVD2SVCD on 1 CDR

[hipster dufus]

Can someone please help?

I`m after an idiots guide to converting a 90min DVD (using dvd2svcd I've got the latest version. 1.1.3 build 2) to fit on a 700mb cdr.

I know it's got to do with bitrate. Now i adjust the cd bitrate in dvd2svcd (the 3rd one down on the bitrate tag)to use 1 cd and change the size to 800 which gives me this reading of ......1232 - 887.

Now my question is do i do anything else do just leave it, 1232 - 887 and just rip and convert?


Does that make sense?


Please help

Thanx in advance!!!!!!

I assume you are willing to accept poor quality as a trade-off? Hmm, 90 mins on one 700/80 min cdr? Well if I just HAD to do that (gun to my head) I would do a few extra things besides what you mentioned above.

1> Use Bilinear resize (Avisynth setup - Top drop-down in Frameserving tab - Compresses better)
2> Would try to resize to CVD (dropdown - mid-low right in same tab) but that may not work on all players. ? Anybody?
3> I would probably add some additional noise reduction like convolution 3D and/or others to allow better compression. We would need to know the version of avisynth you installed to help with that.
4> I would definitely get the FitCD plugin that RB made and use it. See the DVD2SVCD advanced forum for links.
5> Would probably use 2 pass vbr TMPG for something with this low of bitrate, else at least 4 passes with CCE 2.66.01.07 or newer.

Still I think it will look like crap. If it is not heavy action and the lighting is bright and uniform you may stand a chance.

BTW, please don't use multiple caps in a post or header. Please see my diatribe at the top of this forum. Look for the word ANAL. :)

If you really need to do this it will look a little better as a VCD.
Since more bits are alocated to a smaller area.

Hi,

Thanx for your responses.


DDogg;
I followed ur advice and used the "Fit CD". Now finally after almost 24hrs i finished my SVCD. Ok the only problem now is the finished product has a white line border around it and it has this caption in the left top hand corner...."Film pixel 704x553, 9 left border, 11 top border". How the :confused: do i get rid of it? I haven't put it on cd yet. Will it be removed when i put it on cd (i'm assuming not) and if not how do i do the process of ANOTHER svcd without the border and captions?

markrb;
Isn't a SVCD better? So do you think that it will not make a difference if it is VCD/SVCD and can VCD be done with the programme DVD2SVCD?

Once again thanx for all your help. It has made life a bit easier.

You missed quite a few steps when using the AutoFitCD plugin. It is not enough to just install the plugin and then start the encode. Please read the AutoFitCD Readme (it's linked in your start menu, Programs - DVD2SVCD Software Bundle - Support Programs - AutoFitCD Readme). Sorry, you'll have to do this all over.

try using kvcd i converted 8 mile (1h. 43min.) on one 80min cdr with a outstanding quality

PAL 352 X 288 (max 120 min)
MPEG 1 Video
1:1 VGA
CQ 80 (constant quality)

Only because SVCD uses more bits normally.

SVCD spec is for 2530 Kbit Max video, but to make 1 cd you will have to drop that dramatically.

VCD calls for 1150 Kbit video and you will probably still need to use less then this to fit what you want on 1 cd.

SVCD calls for 480 x 480(NTSC) video. VCD calls for 352 x 240(NTSC). So by going with VCD at lower bitrates you can use those bits better.

Bigger doesn't always mean better. Try stetching that small jpg image over the whole screen. It looks better smaller doesn't it?

Now if you decided to use more cd's and give that video more bits to use then an SVCD would look better.

Well I guess that calls in to question whether a CVD 352x480 (1/2 DVD) @1150 in mpeg2 would be better/worse quality that a VCD 352x240 @1150 in mpeg1. I have done the first part as this thread got me tinkering around. It was not very practical but I just finished a 100 minute CVD @956 audio 128 using the script below to feed TMPG for a final res of 352x480. I just used the TMPG Wizard and picked the sustained mode. Btw, the CVD 1/2 DVD res played fine on both my standalones.

mpeg2source("D:\Chamber.d2v",idct=2)
crop(0,60,718,360)
BilinearResize(480,272)
mergechroma(blur(1.3))
Convolution3d("moviehq")
undot()
AddBorders(0,105,0,104)
converttorgb24

Minor noise reduction in this script but nothing too wild. Result was good in any well lit scenes. Quite good in fact and it surprised me a lot. Dark backgrounds, fog, heavy movement in dark lighting did not fare as well and while still very watchable, it exhibited the blocking one sees a lot in the older low bitrate Divxs. Looked about like those to me as a matter of fact. This is all on my 10 year old 35 television. I would expect it would not do at all for the new rigs. Still it is an interesting exercise, if for nothing else, our old attempt to increase compression via filtering using the newer stuff.

I have not seen a thread like that in a while using 2.5 filters except in the Divx, Xvid forums. Maybe one of you that spends a lot of time doing both mpeg4 and SVCD might comment on your favorite NR combinations for Avisynth 2.5x (new thread probably better).

Maybe tonight or tomorrow I will do the VCD. If so, I'll report back.

I blew off the VCD as it technically (I think) does not support VBR and 128 audio. A CVD will and I think that is very important for low bitrate work.

Anyway the news is I used ProCorder for this test instead of TMPG and I am just freaking blown away by the job it did using two pass vbr/highest quality (no time for the mastering mode as it takes forever). I did it by hand and used elementary mode with the average bitrate set at 956 and the max set at 2530. After it was finished I ran pulldown.exe on it and muxed it up with BBMplex. Those of you who have ProCOrder should try this. Hell, this was good enough that I might even go to CVD 90 mins on certain encodes as a matter of course. Presently (I think), D2S is not passing the CVD sizing parameter to ProCorder so I don't think this would work at the moment for automated encodes. I will have to double check that to make sure and report back.

edit: See sticky at top of forum for beta 6 that now works correctly with CVD and ProCorder.

While your on this CVD testing thing. Try doing a CCE CVD @ 1100 128Audio, again with a clean DVD but use this script;

BicubicResize(352,480)
FluxSmooth(3,3)
Blockbuster( method="noise", variance=.5, seed=1 )
asharp(1,3,1,True)

And let me know if it is better than what you did previous.
I use this script for all my DVD's and find it to be awesome and fast.
Let me know thanks

I had normally restricted my backups to 60minutes on an 80 cd-r, encoded Via CCE with 4pass VBR, PAL-SVCD res and 224kbps audio, most other settings were as default. But two disc back-ups are annoying when it comes to entertaining the kids so i attempted a single disc back-up of shrek. I changed the bitrate as to fit 100minutes to a 80min cd-r, increased passes in CCE to 5 and changed the image quality priority for CCE to around 10, and dropped the audio down to 44.1kHz 128kbps joint stereo. The results were quite outstanding on my TV, but not exactly achive quality when viewed on a projector. Side-effects were blured immages in high action sceenes, but good enough for the kids. The main infuence on the quality (apart form the bit rate) was the image quality priority in CCE. As a result i have now pumbed my usual capacity to 65 minutes on an 80 minute cd-r, and 4 pass VBR, and the priority set to round 13 to 15.
