Hi together!

I want to encode a relatively short movie from 720x??? sized source in best quality possible.
Now I wonder if DVD players are capable of playing SVCDs with DVD resolution. Have you guys ever tried a 720x576 oder 720x480 or whatsoever resolution using svcd?

How successful was your product?
Tell me. Thx.

I've encoded several MPEG-1s in 704x480 resolution and then muxed and burned as SVCD, so I'd assume MPEG-2 would work in the same way. I would reccomend using 704 instead of 720 though.

In the end I think your gonna have to just test out your dvd player and see what its limitations are. For instance, my dvd player won't play the 704x480 resolution, but it will play the 740x480 resolution with max bitrates ~5000 with mpeg2. I haven't really tried pushing the limits much more than that because at 740x480x5000 its allready WAY too big to put on CDs and I don't have a dvd burner ;p 528x480 looks really good on my tv.

Thanx a lot so far.
The problem is: I don't have a DVD player which I could use to test (yet).
I'm going to buy one in 2-3 months, and am already converting videos I get now to (S)VCDs for future compatibility
I know, until I get a DVD player it's a question of luck whether my non-standard (S)VCDs will run on it or not.

I'll do the 704 res using SVCD-compliant bitrates and audio.

I've tried it.

The bad news is, your video quality is going straight to hell.

The good news is being able to say, 'hey, I encode at DVD res!!'

It looks great on paper. It really looks like hell on a TV.

Stick with KVCDx3@cq75...

Hope that helps,

Steve

I have done more than 50 DVD rips with res 720x576/480 or 704x576/480 with min 300 and max 2500 kbps with CQ and CQ-VBR templates . It's really good and almoast DVD quality except the sharpness of high >5000kbps which results real cristal clear picture . On my DVD player playback is smooth with no prob . To get 2hr movie with best quality use , if u can , 2 - 90min CDR with CQ close to 80 . I beleave result will not disappoint u .

Hi sToRm,

basically it's like Reno said. Quality will go down if you encode at 720 / 704. There have been some discussions about that some time ago. The point is, that you have less 'bits per pixel' if you raise the width or height of your encode.
If it's like you said, that the movie you want to encode is relatively short, then the average bitrate is hopefully high enough to cover most of this. BUT the max. bitrate will still be 2748 - audiobitrate (2588 or 2620 normally) and that _certainly_ brings down the quality! No matter, how long your movie is!
In the end you'll have a better looking movie, if you stay at 544 / 528. The sharpness of the movie will be lower, but unless you have a very good TV with a big screen, you wont see any difference anyway!!

ciao,
Malcolm

Have to say I disagree, I encoded a 2-disc version of LOTR2 at 704x480 with only SpaceDust() and Convolution3D(preset="movieLQ"), got a CQ of 69 and it looked great apart from some "mosquitos" but you couldn't even see them on a TV. I could probably have made it even better with FaeryDust, MergeChroma/Luma, and Blockbuster noise as well...

Gotta say I agree with Pyro ! 704x480 will look very good, and you still have enough room for a high CQ, if you smooth the picture properly. Try this script for this resolution. It gives me good results, and you can easily put 90 min. on one CD, with VERY good quality.

Code:
LoadPlugin("E:\MPEG-Tools\FitCD\MPEG2DEC.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\dustv5.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\legalclip.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\sampler.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\convolution3d.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\gripfit_preview.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\temporalcleanerold.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\dctfilter_YUY2.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\STMedianFilter.dll")

Mpeg2Source("C:\Insomnia\insomnia.d2v")

LegalClip()

GripCrop (704, 576, Overscan=0)

Gripsize()
mergechroma(blur(1.58))
mergeluma(blur(0.075))

TemporalSmoother(radius=2, strength=3) 
SpaceDust() 
TemporalCleaner(ythresh=5, cthresh=10) 
STMedianFilter(7,15,4,7,7,15)

GripBorders()
Letterbox(0,0,22,22)

DctFilter(1,1,1,1,1,.5,.5,0) 

LegalClip()

#Sampler(length=24)

ConvertToRGB24
