Which resolution do you prefer for MPEG-2 on CD-R/RW?

[j1d10t]

If I can, I prefer 704x480 for MPEG2, but given the choices of this poll

[i_am_dave]

I also prefer 704 x 480, but at least 352 x 480 IS a standard DVD resolution.

[telemike]

Most DVD players can play SVCD 480 x 480 or CVD 352 x 480.

Just curious at to what most people prefer to encode at for these.......

[freak_in_cage_10k]

i am in the process of evaluating the benefits of CVD over SVCD (UK pal)- i suspect i will completly turn to CVD, pitty i hadn;t discovered CVD a few years ago, i have over 100 SVCDs which will need to be converted so they work on DVD-R when i get a dvd burner!

I think the main benefits of CVD over SVCD is the ease that CVD can be converted to DVD-R with full compatability more easily!

[BJ_M]

i prefer 1920 x 1080 and just about as much 1280 x 720

[j1d10t]

BJ_M:
With those resolutions, they play in your DVD player? What do you burn them as? DVD? XSVCD?

[Conquest10]

BJ_M, what do you use to encode at that resolution?

[txpharoah]

Most DVD players can play SVCD 480 x 480 or CVD 352 x 480. Just curious at to what most people prefer to encode at for these.......

Actually, these days most DO NOT play SVCD 480x480 resolution.

[BJ_M]

BJ_M:

they are high definition files and I play them in a high def server , they are compressed as either mpeg2 or using a special type of wavelet compression ..

@ telemike,

I just voted 352x480.

I prefer this because of the following:


Though, I have yet to finish my analisys of 352x480 vs. 480x480, but, then
again, it doesn't really matter all that much these days, as DVD media is
getting closer and closer, and hence the comformity/comptabilitiy w/ the
use of 352x480 and 720x480 resolutions.

So, if I need to, or decide it's time, the next level I jump to would be the
720x480. Though, I'm not saying that I don't "already" use the 720x480
res., as I do use this too in todays encodes. It just all depends on what
I'm doing at the time and what my goal is and so on and so forth.

So, in summassion, (spelling) my two main res. are 352x480 and 720x480 !!

But, there are more issues to consider than just all these different res. too.
But, I'll spare you all the explana's becuase I burning up my energies, all
the while I'm in a debugging regimen and eating and so on and so forth hehe..

Have a good evening all.

For any analogue captures, I use 352 X 576 for final framesize
For DVD backups, I use 480 X 576
For some stuff wanted to have it just for do it so, I use 352 X 288 (for mpeg 2, excellent at ~1500kb/s, like VHS for true!)

I can't answer for sure what to do with the 544 X 576 DVB transmissions... Convert them to 352 x 576 or 704 X 576? Hmmm

[tgpo]

a high def server

A XServe?

I voted CVD over SVCD for a few reasons. Basically, when you do decide to get the DVD burner, you cna just dump the CVD into your authoring program and burn (if you did a non standard CVD with 48mhz audio instead of the standard 44.1mhz).

ON CVD vs SVCD, MY PERSONAL EXPERIENCE is that there is no difference and the CVD takes up less space on a CD or DVD.

With the CVD's that I have done (when I finally closed the GOP ), I can fit 2 movies with high quality onto a DVD-R. I could fit 3, but I encoded my CVD's at a higher bit rate (close to the max CVD bit rate).

What I do to make CVD's is that I use a program called DVD2SVCD. I change the number of CD's to 1 and the size to 2200 (2 movies will fit on a DVD-R that way). I dont make images. I AM SURE TO CLOSE GOP's!!!! and do a 1 or 2 pass using CCE (VBR).

[energy80s]

It depends on what the source quality is like on the files I am encoding.

For most D-Sat captures I use 352x576 as the source is shite to begin with. For higher quality material I use 704x576 (cropped D1) and for DVD copies (few and far between) I use full D1 at 720x576. Don't use non-standard resolutions like 480 or 528 as these are not supported in the DVD spec, and just because your existing DVD player will play them doesn't mean that a replacement will - and you don't want to be left with discs you cannot watch!

[edsmith77]

I actually like 352x480 because it is a DVD standard. However, I have recently switched to 352x240. Which if not mistaken is also a DVD standard.
On my system, I desire to keep the CDRs to a maximum of two (2), hence at 480 the bit rate needed only produces blockiness. However, if I drop the vertical resolution to 240, then there is more than adequate bitrate and no blockiness.
Yes, yes I know that the picture quality is "somewhat" lower but to my finely tuned eye, I just cant see it.

For most authoring package, you're mistaken. 352x240 MPEG2 is not while 352x240 MPEG1 is accepted (1150-1856k bitrate range).

[Cecilio]

Hey can anyone answer me this why do people say that CCE is better quality than TMPEG look i belive everyone that has very very good experence with DVD to CVD creation. its cause i do my CVDS using DVD2SVCD and i have made 100 CVDS using TMPEG and they are all excellent quality only one pass and motion estimate search fast. now this is my problem when i zoom in with 4x in a movie i made with TMPEG i see no pixels, while when i use CCE with 4 Pass VBR max 6000 min 1100 avg 2000 i zoom in at 4x and i see a bunch of pixels. and its been like that for several movies. i use image qual. priority at 5 and i close GOPS and i dont use Zig Zag scanning order either. what can i be doing wrong. cause from the looks of it to me it seems that TMPEG might get ME better quality for my CVDS plus faster cause 4 PASS takes too long.

BJ_M, what do you use to encode at that resolution?

You can use both Tmpgenc and Mainconcept to encode at these resolutions. You need to change the encoding profile from MP@ML to MP@HL (High level), at least in Mainconcept.

Of course, to make sense, you need to have adequate resolution source, and the best widely available (DVD) is not enough.

However, the blue ray players are supposed to have HDTV specs, which, if I have understood correctly, are the MP@HL (1920 x 1152). Nice way to fill up a 27Gb disk.

To focus to the thread's subject, initially we were happy with the VHS resolution (200 lines). The VCD was a nice thing and it can be made to look good with VHS material. Then DVD promised the best in quality. DV Camcorder material is best encoded in DVD resolution and bitrate (VCD wastes the quality). I suppose that in a few years camcorders will have 3.5 Mpixel CCDs and we will be discussing how badly DVD encoding hurts the video quality of our movies. :P

It's not the size of the imaging chip but the resolution of the recording meduim that counts.

I agree with you, although I don't fully understand what you mean

DV Camcorders have something like 0.4MPixels and record the video in that resolution. (Of course digital cameras have more pixels and allow you to downgrade image quality on the spot by storing them in lower size). But, I'm sure, that when camcorders increase their CCD resolution they will store the extra detail in the video stream.

[BJ_M]

get a Thomson Viper video camera. It has 3 x 9.2-million pixel ccd's (@ anywhere from 24 - 60 fps progressive)

even blow your still image camera out the door ..

@ BJ_M..

>> get a Thomson Viper video camera. It has 3 x 9.2-million pixel ccd's
>> (@ anywhere from 24 - 60 fps progressive)

Yeah, but at how much $$$$.$$ are we talking about here ??

I think that the cheapest Progressive DV cam goes for something like around
$1600 (give or take)

As for CAMS's..
I just upgrated my old Canon ZR-10 to a Sony TRV-22. This is an Interlace
(though Progressive in some respect) type cam. But, there's a progressive
(I call it semi-progressive) feature that I've ben experimenting w/ that, so
far, looks pretty good on my monitor. I have to burn some CDRs as tests
to "really" see how they come out. Hopefully, this new feature will be worth
the effort. Oh, and no Interlace to be found in the .AVI ..which means,
no de-Interlaceing either !!
I'm still testing this out, as I don't have lots of opportunity to test in better
light conditions. I ususally test during the night Anyways..
Also, to note.., and no-one has found this feature yet. Looks like I'm the
first thus far hehe..

I can't wait when the TRUE progressive cams come out, and in LOW prices.
That will be the day

Later guys.

I like the good ol' 480x480, but that's because I want true SVCD. (I just started in the "advanced" SVCD school, so I'm sticking with that until I know everything I want to learn.) It seems to be the most portable resolution, at least in my experience.

It's not portable to anything.

[energy80s]

Yeah, the SVCD resolution is not compatible with anything other than specific SVCD capable DVD players. Better go for either 352, 704 or 720 as your horizontal resolution. These are both broadcast and DVD standards.

[RabidDog]

I must admit I do notice a quality drop between cvd and svcd ergo I will go for 480x576 when I do some tv cap i might use 352 ?? svcd2dvd promises painless changeover to DVD (so you dont need 352 for future comaptibility) but I have no experience with this software.

[K2]

720x480

[MJPollard]

Which resolution do you prefer for MPEG-2?

Since this poll is biased against the DVD format (only SVCD and CVD? c'mon!), I can't officially cast my vote for 720x480. I don't bother with anything else, but that's probably because my DVD player won't play any user-burned discs other than DVD.

[telemike]

I will have to try doing DVD resolution and see if my player will accept it. My Magnavox MRD200 DVD home theater plays 480 x 480 SVCD's flawlessly with great clarity. Almost as good as dvd except for smoky scenes. I prefer the extra sharpness of 480 x 480 as compared to 352 x 480 (or 352 x 240 VCD).

I do not plan on converting my SVCD's to DVD-R in the future. If I ever get a dvd burner I will make new backups using the dvd9-5 programs.
