is svcd better than vcd

is svcd better than vcd as in quality and sound ? if so is it harder to make a svcd than a vcd ..

[Baldrick]

video quality is usually bettter but the audio is the same. checkout dvd2svcd.

will do thanks. :)

audio is the same? i thought standard VCD 2.0 is 128 kbit audio while SVCD is 224 kbit audio.

1) resolution is higher

2) usually video bitrate is higher (also SVCD uses VBR, while VCD can only use CBR)

3) MPEG-2 compression is better than MPEG-1 compression

4) audio in SVCD is higher bitrate than audio in VCD

i'm just comparing standard VCD 2.0 w/ standard SVCD....not any xVCDs or SxVCDs or wutever

A standard vcd uses 224kbits for audio. Svcd can use between
32-384kbits. At 224kbits mpeg1 audio layer II (what both vcds and svcds use) is about cd quality so yes even though svcd supports higher bitrates for audio than vcd the quality is still about the same.

Svcd does support multichannel mpeg audio which is much higher quality than what a vcd can offer, however, the extremely limited hardware support makes this almost unusable.

1) Yes
2) Yes
3) No, mpeg1 and mpeg2 compress the same. At the same settings mpeg1 and mpeg2 will look the same and be the same size.

4) Yes it can be but it doesnt really matter.

The other detail nobody has mentioned here is that SVCD has double the vertical resolution of VCD which means double the detail.

A well made SVCD of a VHS tape is near indistinguishable from the original. A well made VCD still degrades in picture sharpness because of the halved vertical resolution and the de-interlacing process required in the reduction if you capture at full vertical res.

I've been doing VCDs for a year or so and only switched to SVCDs recently when I got a new DVD player. The difference is remarkable, even on a 53cm T.V.

Hope this helps,

if wut adam sez is true about MPEG-1 and MPEG-2 compressing the same...then i don't see what's the point of Sefy's hybrid SxVCD (or something like that)

i believe Sefy mentioned something about MPEG-2 giving better quality with the same file size, so having 800 megs of MPEG-1 compressed video is going to be worse than having 800 megs of MPEG-2, assuming all other settings are equal....

otherwise, what's the point of SVCD if we can have MPEG-1 w/ the same resolution and bitrate as SVCD (xVCD)

Because that template uses vbr with mpeg1. If your dvd player doesnt support svcd then there is little chance you will get it to play an mpeg2 file regardless of how its encoded. However, if your dvd player supports vcd then there is a possibility it will be able to play a vbr encoded mpeg1 file. Basically the purpose of the template is to give the benefit of vbr encoding to people who don't have svcd compatible dvd players.

I don't know if your misquoting him or not but that is not true. I think Sefy probably meant that the mpeg2 file encoded with vbr at a size of 800mbs will be better quality than an mpeg1 file encoded with cbr at 800mbs, which of course is true.

Realistically speaking mpeg1 and mpeg2 often don't encode the same, quality-wise, due to imperfections in the encoder. For example cce is considered a very good mpeg2 encoder but sub par at encoding mpeg1. An mpeg1 file and an mpeg2 file encoded in cce at the same settings very well may look different, but theoretically the two standards, mpeg1 and mpeg2, should look identical at the same settings, and in all cases they should be roughly the same size.

otherwise, what's the point of SVCD if we can have MPEG-1 w/ the same resolution and bitrate as SVCD (xVCD)

I think the answer to this is pretty obvious isn't it? Xvcd is far from being a supported standard. I know that the svcds I author will play on any svcd compatible dvd player. The same cannot be said for xvcd. Additionally, the svcd standard and the mpeg2 standard allows for functions which simply are not possible in a vcd or xvcd ie: interlaced video, overlay graphics (up to 4 switchable sub streams,) multiple audio streams, and multichannel mpeg audio.

is svcd better than vcd as in quality and sound ?

Look to the upper left of this page, WHAT IS vcd and svcd. There are sample files. Download them, make into vcd/svcd as it instructs, and let your eyes and ears be your trusted, impartial judges.

is it harder to make a svcd than a vcd ..

Look to the left again, just a little lower, HOW TO author. Compare and contrast authoring both a vcd and a svcd.

poopyhead, just like Adam said, that was exactly the purpose of the SeVCD, it is for those who can't play SxVCD which uses MPEG2 VBR (usually a DVD that cannot play SVCD), so taking advantage of the VBR i've implied the same thing to the SeVCD using VBR.

Also regarding the SxVCD using VBR will give you same or better results then a regular VCD encoded at CBR, when both file sizes are the same.

I Apologise if it has mislead you in some way, english isn't my primary language and I might have phrased things incorrectly, sorry!
