newbie did 1st dvd to vcd - successfully!!!!!

[Fluffbutt]

i used Dvd Decrypter 3160 to rip the vobs, and DvdX 22 to reencode to vcd.

Panic attack when I saw after 2 1/2 hours of encoding that the final vid mpg was 795 meg - ahhh it won't fit on a cd!!!

Rush around online to find a way of killing 10 mins (about 100 megs), I'd already removed the end titles and the crappy leadin to the movie (an intro thing..).

THEN I found a tutorial that said Nero will do a vcd and it'll accept up to about 810 megs file size (HOW?????)

End result - a vdc 80 minutes that plays in my LG Dvd player .... woohooo!!!

Now, Questions - the quality is a bit 'jpeg'ish (you know, artifacts) - how can I reduce this effect?. Sound synch is near perfect tho..

VCDs (similar to audio CDs) are based on running time, not filesize. You can put approximately 80 minutes on a 700Meg CD-R...

[UncasMS]

it has nothing to do with running time.

the key is: different error correction

What kind of artifacts like pixel's? if so there so no way to fix it. You are going from around 6 gigs to 800 megs you are going to burn to SVCD to get a little bit better quality

So basically it's not me, it's the compression type for vcd.

So it follows that an 'important' movie should be coded to svcd and spread over two cd's (is that the same as vcd 2.0, as my dvd player shows in its documentation?).

I imagine that changing the audio rate will reduce the file size, but that'd lead to audio/video mismatch... hehehe asian movies!! (mouth moves, 30 secs later speaks...).

HEY!!! thanks you guys, this has been interesting and fun. I thought this would take ages (the tutorials say 8 hours - mine took 2 1/2, Inc the dvd rip), and would probably fail. I'm quite pleased my first go went so well.

One other thing - I tried smartripper before Dvd Decrypter, but it just sat there for an age doing absolutely nothing.. any ideas why (and yes, I clicked the start button lol).

I am not sure about the VCD 2.0 but if your DVD player documentation says it is the same go ahead and give her a try. If you aren't already I would try to use DVD2SVCD which is the easiest program I have ever used. It takes your DVD and encodes to a SVCD (MPEG-2) complient file.

[chickeneater]

i second that.

No, SVCD (SuperVideoCD) is NOT the same as VCD 2.0. VCD2.0 is the improved (and currently used) version of VCD1.1. Both are MPEG-1 formats, while SVCD is an MPEG-2 format.


(If you're curious about the differences between VCD 1.1 and 2.0, DVDRHELP.COM offers the following details:

"Video CD 1.1
This is the most basic Video CD specification dating back to 1993 4 , which has the followingcharacteristics:
• One mode 2 mixed form ISO-9660 track containing file pointers to the information areas.
• Up to 98 multiplex-ed mpeg-1 audio/video streams or cd-da audio tracks.
• Up to 500 mpeg sequence entry points used as chapter divisions.
The Video CD specification requires the multiplex-ed mpeg-1 stream to have a cbr of less than 174300 bytes (1394400 bits) per second 5 in order to accommodate single speed cd-rom drives. The specification allows for the following two resolutions 6 :
• 352 x 240 @ 29.97 Hz (ntsc sif).
• 352 x 240 @ 23.976 Hz (film sif).
The cbr mpeg-1, layer II audio stream is fixed at 224 kbps with 1 stereo or 2 mono channels.It is recommended to keep the video bit-rate under 1151929.1 bps 7.

Video CD 2.0
About two years after the Video CD 1.1 specification came out, an improved Video CD 2.0 standard was published in 1995. This one added the following items to the features already available in the Video CD 1.1 specification:
• Support for mpeg segment play items (SPI ), consisting of still pictures, motion pictures and/or audio (only) streams was added. See Section 1.6.2 [Segment Items], page 9.
• Support for interactive playback control (PBC) was added.
• Support for playing related access by providing a scan point index file was added.(‘/EXT/SCANDATA.DAT’)
• Support for closed captions.
• Support for mixing ntsc and pal content.
By adding PAL support to the Video CD 1.1 specification, the following resolutions became
available:
• 352 x 240 @ 29.97 Hz (ntsc sif).
• 352 x 240 @ 23.976 Hz (film sif).
• 352 x 288 @ 25 Hz (pal sif).
For segment play items the following audio encodings became available:
• Joint stereo, stereo or dual channel audio streams at 128, 192, 224 or 384 kbit/sec bit-rate.
• Mono audio streams at 64, 96 or 192 kbit/sec bit-rate."

to whom was that addressed?

To chickeneater

"to whom was that addressed?"

I'm speculating that you're addressing me, regarding my previous post to this thread.



1) This is a thread started by "Fluffbutt"

2) "Fluffbutt" asked, "So it follows that an 'important' movie should be coded to svcd and spread over two cd's (is that the same as vcd 2.0, as my dvd player shows in its documentation?)."


So, who do you think it was addressed to? - It's totally pointless for you to have posted your question, in light of the fact that the information is correct, regardless of who in this thread I may have been addressing...

(Perhaps you might want to consider deleting your post ;>})

Perhaps you might want to consider deleting your post

or perhaps you might want to consider sticking to the board rules (which you seem to enjoy quoting these days) and try to be polite!

I found out how to remove to jpeggie artifacts - I re-encodes the vob to vcd using dvd x 2.2 as before, but this time I set it to use Bicubic P3 scaling - end result is a video that looks VERY close to the dvd original (a little less bright and sharp tho).

The first conversion frame rate was 12.5 frames a sec, with bicubic scale it went down to 10.8 fps (2 hrs 30 min to 3 hrs 12 min) - well worht the extra time.

As an aside it strikes me that this encoding is a good way of doing a processor-only (no vid card or hd) power/speed test.

Congratulations on resolving your dilemma ;>}
