kvcd - dvd

[yoh6781]

hi,

has anyone tried using the 352x240 ULBR (can reach 360minn per cdr) kvcd template to make a dvd-compliant mpg2?

this template caught my eye coz if it can make a cdr fit 360min, imagine how much video you can put in 1 dvd+r....

any help in making a dvd-compliant mpg2 would be greatly appreciated

The two terms "kvcd" and "dvd-compliant" contradict each other

The day I see 6 hours of video on a CD, enjoyable to watch on my TV, I'll eat my hat, and any assortment of other accessoirs.
You could of course try authoring it just like any other "VCD on DVD" project to see how it looks.

Have you tried to fit 360 min on CD? If not, first try this. I am sure you will be disappointed, but who knows...

jimmalenko: ooops.. sorry about that... i meant that the resulting mpg will still be usable for any dvd authoring programs. i used the dvd-lab and it stopped me from using the finished mpg

mats.hogberg & Abond: i made 1 mpg file out of it and it was 80-90mb (23min), quality was acceptable for me

I don't think 352x240 mpeg-2 is a valid DVD file.

Once you go out-of-spec, compatibility goes out the window.

[yoh6781]

352x240 resolution is usable as a mpg2.... there's a template for it in tmpgenc, template is for LQ dvd

[Nelson37]

Usable as MPG-2? Template in TMPgenc? That may be so, but according to the DVD specs in the What Is section, I was correct. 352x240 MPG-2 is NOT valid for DVD. Must be MPG-1 to use that resolution.

According to mpeg.org's specifications, 1/4 D1 mpeg2 is legal.

Yup, that's 1/4D1, and the "k" template will simply change the GOP to about 5000 B frames.
Quality is about that of VHS.
Author in DVDLab, because most others will choke.

Uhhhh .... yes it is a valid DVD resolution using MPEG-2.

NTSC (NTSC Film)

Video:
Up to 9.8 Mbps* (9800 kbps*) MPEG2 video
Up to 1.856 Mbps (1856 kbps) MPEG1 video
720 x 480 pixels MPEG2 (Called Full-D1)
704 x 480 pixels MPEG2
352 x 480 pixels MPEG2 (Called Half-D1, same as the CVD Standard)
352 x 240 pixels MPEG2
352 x 240 pixels MPEG1 (Same as the VCD Standard)
29,97 fps*
23,976 fps with 3:2 pulldown = 29,97 playback fps (NTSC Film, this is only supported by MPEG2 video)
16:9 Anamorphic (only supported by 720x480)

It goes out of spec with a GOP length over 18

No. Far lower. The x240 is half that of the visible VHS signal. It gets blurry, and it must be deinterlaced, which adds even more obnoxious errors.

[Nelson37]

Sumbitch. Missed that one, eyes went right to the VCD-mpg1 notation on same page.

I find regular VCD to be VHSish at best. Can't say I've tried, but I seriously doubt the quality can be maintained while lowering the bitrate to and below 1/4 of VCD?

Absolute crap. Better to use Sefy's
SXVCD template with standard GOP
at pal 352x288@25fps (mpeg-2)

You get up to 8 hours of sub VHS quality
on a 4.3 gig dvdr, it works on any DVD player,
and is watchable up to 30" (80cm) screen.

The "K" method is blurry, non compliant and
frankly not worth the effort imo. The premise
that the "k" method is VHS quality is laughable

[Sefy]

Thank you for the Compliment, I still use my SxVCD today since it's totaly DVD Compatible, well, basicly if you use DVD Template and reduce bitrate and resolution to VCD it will be the same thing 8)

[reboot]

OK, I hunted...Sefy, can I get a copy of your template?
Are you saying it's basically the DVD template, but at 1/4 D1, and roughly 1150kbps?
I want to compare it to the KDVD templates.
Although I rarely use them any more (disks are just too cheap), I found the full D1 template was reasonable (hence my "about VHS quality" statement)...I had forgotten we were talking about 1/4 D1

[Sefy]

Basicly if you use TMPGEnc 3XP, just use a DVD Template, put resolution on 352x240 (or 288 if you are PAL) and let TMPGEnc use whatever Bitrate the movie can fit in VBR on your disc 8)
