Oversized MPGs...To cut or not to cut...?

[Dionymnia]

Someone earlier in this forum said that a 74-min CD could hold @740 megabytes, but all of the 74-min CDs that I have say they hold 700 megs, and it doesn't slip past EZCD 5.0, as it says that it's too small...so am I missing something?

With that in mind, I have a 730-meg MPG that I want to make into VCD, and I think I need to cut it...however, it seems that TMPGEnc won't cut it after I've "fixed" it with MPG-Corrector...I have checked and it will cut a MPG file that haven't been "fixed", (thus having a system clock # EZCD won't accept), and then it won't cut the same MPG file after it has been through MPG-Corrector...is there a program that will, or is there something else to do? This may be a moot point, if there *is* a way to put this file onto one CD, but I'm not sure what to do here...

Thanks,
Dio

A 74min/650MB CD-R can fit 74min of VCD compliant MPEG-1 or about 740 MB.

A 80min/700MB CD-R can fit 80min of VCD compliant MPEG-1 or about 800 MB.

I don't know how good a VCD authoring/burning proggy Easy CD Creator 5 is, but you can definitely burn up to limit if you author an image with VCDImager and then burn the CUE/BIN with CDR-Win.

To hell with ezcd creator! Find yourself a fully registered copy of Nero 5.5.2.4 and burn yourself some compliant discs!

In Addition to the VCD.mpeg data file there are also files and folders, I think around 70Mb this is enough sometimes to make it too large for the CDR.

Why do you want to loose some of the movie or quality fitting them on 1 cd. What do your CDR cost ? What would the movie cost ?

Quite a lot of the time, the movie is only a few Megabits over, but I will still put them on 2 disks, rather than cut 10 min of the movie, or lower the quality.

Easy Cd Creator, works very well. Never had any problems with the VCD's it has made. 200 +

Unless you are creating a lot of menus, the total size of the first physical track should be no more than about 20 seconds (this is with the CD-i app). This equates to about 3-4 Mb. The minimum size the first track can be (which will necessitate you not including the CD-i app) is 6 seconds long.

If you are using MPEG still images, you can consider each still taking up 2 seconds each.

Thus, it should be quite easy to work out how much you can fit. On a 74 min CD-R, you should EASILY be able to fit a 73min 30sec video track without overburning (if you only have 1 or 2 menu screens).

Similarly, on a 80 min CD-R, you should EASILY be able to fit a 79min 30sec track without overburning (same conditions as above).

This equates to about 730MB and 795MB for the two respective media sizes.

If your burning proggy can't handle this (??Easy CD Creator), there is a problem with the proggy.

Oops 70Mb, that should read 70Kb.

Easy Cd Creator creates the folowing folders

Cdda (Empty)
Cdi (Empty)
Karaoke (Empty)
Mpegav (Mpeg file)
Segment (Empty)
Vcd (70Kb aprox)

Other information from roxio (90 Min)
According to the official Red Book standard, the maximum playing time for an audio CD is 74 minutes. This specification has been stretched by everyone in the industry to support 80-minute audio CDs. However, anything over 80 minutes clearly violates the specification. Most CD players and CD recorders will therefore have problems reading or writing 90-minute discs. The following problems can occur:

CD player doesn't recognize the disc
CD head bounces out of the groove
CD player can't find tracks after 80 minutes
CD can't be copied
CD can't be read (90+ minute CDs use a very tight groove)
CD created may contain same sector number twice
CD created may contain a sector with a negative number
Most of these problems will result in an unreadable CD. Worse, it is even possible that trying to record or play a 90+ minute CD could physically damage the CD player or recorder. WE THEREFORE STRONGLY RECOMMEND THAT YOU DO NOT USE 90+ MINUTE CDs!


Overburning

No Roxio CD-R software supports overburning at this time.

I think Roxio is just being overly cautious...

80min CD-R have been official added (must be Orange Book part2 I think).

Surprisingly many burners and player do in fact read 90min media without problems. There was a recent article on this in Tom's Hardware: http://www.tomshardware.com

If a CD drive can't read a CD, it shouldn't damage the drive in any way realistically.

BTW, the minimum size of the first track of a VCD is 6 seconds long (about 1 Mb). The ISO filesystem just reports the total sum of the sizes of the files in the first track. This, however, isn't the true size of this track.

Also, the figures I gave in my last post DO NOT involve overburning at all.

i just cut one whole movie The Atlantis (after encoding them) into 2 files and i used tmpegenc. first i opened the whole file and start from 0:00.0 to whatever and pressed start to start calculating after naming an output file. 2nd part start from where you stop and press start again after naming your 2nd output file.
