3vcds into one dvd movie

[wolfe805]

Ive been searching and searching thru these forums... ive probably found maybe 2 actual guides/instructions on how to convert vcds to dvd... but i want to get 3 vcds onto 1 dvd... they would obviously fit size wize... but ive been seeing things bout mpeg 2? alls i can seem to get out of all the instructions i follow is to come out with an mpeg1video with mpeg2 sound haha... i was hopin sum1 could give me or direct me to an easy to follow and not complicate guide to making this happen... i found sum guides with using 10 different progs... i dont think thats necessary... just tell me whut i need and how to do it... thnx guys

Isn't to hard to put VCD on DVD, if you have the right software. For the moment I don't have a DVD burner, but I was interested about this subject (and I will have a DVD burner soon...).

If you have the MPEG-1 files, you don't need to convert them to MPEG-2, because DVD Video format allow MPEG-1. You only need to convert the audio from 44.1 kHz (VCD compliant) to 48 kHz (DVD compliant).

You can put up to 4 VCD on 1 DVDR, but depend by the movies playtime. Do the math (if I wrong please correct me):

VCD bitrate is 1,150 kbps (video) + 224 kbps (audio) = 1,374 kbps
This mean 1 second of movie have 1,374 kb (kilobites)
In kB (Bytes, 1 Byte = 8 bits) 1,374 kbps = 171.75 kBps

1 DVD can hold ~ 4.37 GB ~ 4,474 MB ~ 4,582,277 kB (note than the 4.7 GB is 4.37 GB because of the 1,000/1,024 transformation).
So, 4,582,277 kB/171.75 kB ~ 26,679 seconds
26,679 seconds = 444 min 39 sec = 7 h 24 min 39 sec

26,679 sec / 4 (nr. of movies) = 6,669.75 sec/movie ~ 111 min/movie (average value)

In theory, you can put 4 movies, but you need to see the playtime so the total not exceed the 7 h 24 min (check www.imdb.com or your VCDs with AviCodec to find these values). Many movies have less than 111 min (usual 100-110 min). If you choose to put just 3 movies you have an average of ~ 148 min/movie, enough I think.

I don't know if the 44.1 kHz to 48 kHz conversion will change the bitrate of audio, but I guess that the answer is yes. If so, the final values are:

6h 18 min 32 sec
94 min 38 sec for 1 movie (4 VCDs on 1 DVDR)(maybe not enough)
126 min 10 sec for 1 movie (3 VCDs on 1 DVDR)

One trick is that you can re-encode the audio from 224 kbps (at 48 kHz) to a lower value (160 or 192). You obtain space, but will decrease the audio quality.

And one more thing: if you want menus, you need to have space for these, too (not to much).

Here you can find a lot of guides (available from the "Guides" on the left)

You got pretty sound advice on the last post. You have to demultiplex the VCDs, convert the audio to 48Khz (I use SSRC) through TMPG and multiplex back together. Changing the sampling rate from 44.1 to 48 doesn't necessarily make the size bigger(although I do size up a bit).

Fantastic post. Third post for this member yet has done the appropriate study. Encouraging. I almost feel like I should donate a DVD burner.

yes very nice post... but i didnt know that there was a time limit for the disc like a cd-r... i think the movie is like a total of 3hours and 15 minutes... that would pretty much be a whole disk right? or how much room is left? i dont really follow the kbps ratio math... im newb at this... but thnx so much for help... if anyone else can help me with this new problem thnx

Well, there's not a "time limit" really. The amount of stuff you can fit on a single disk is dependant on the bitrate it was converted at. Standard VCDs (which we are assuming) has a video bitrate of 1150bps. Audio can vary a bit but most of mine are 192kbps (or maybe 224) I think. I don't have a calculator but I'd be willing to be you could get 3 and a half hours of 1150kbs (plus audio) on a DVD easily.....

ok thnx... dang this is much harder than vcds lol... bitrates? oi.... time to hit the faqs again lol... thnx so much guys

?? Is this a joke? I am a newbie in DVD area and if I wrong please correct me.

Joke? I highly doubt it....

I have done this. I use IDO Buster to get the mpg's of the VCD's. Then load them in TMPEGnc DVD Author, and make the VIDEO_TS folder and files. Then burn to DVD. Works great. I have fir over 6 hours on a dvd.
