Trying to fit 86 mins drama into 1 80 mins CDR

[vod]

Hi Guys,

I am currently trying to fit 2 episodes of drama. each of them has a playable track of 45 mins. after cutting the neginning and end of the track, it is now around 43 mins.

Is there anyway that i can fit 2 of them (43 mins*2) into 1 80 mins CDR? nero overburn does not allow that.

If shrinking down size of the track is the only option, how do i go about doing it? what kind of setting should i use in TMPGenc?

Btw the vcd is a dual channel/ dual sound vcd.

Thank you.

Regards,
VoD

This is a very simple matter of Calculating Bitrate, I would suggest using a Bitrate Calculator.

Overburning isn't a way to fit twice the amount on a CD. You will have to lower the bitrate so it fits. There are also templates out there that will help you fit more per CD, but the more you fit on a disc, the worse it'll look.

Demux your mpeg files. Re-encode the audio with HeadAC3he at 128Kbps. Mux with BBMpeg. That should probably give you the extra space to fit in one CD.

Lower the bitrate in TMPGenc:
Open it then close the wizzard.
Load the settings fot a vcd (pal or ntsc).
Then load the settings in the folder of TMPGenc>Extra>unlock.
Then you can see with the settings that everything is unlocked.
Now go to System then change the option to Mpeg-1 Video-cd (non standard).
With audio you can lower tha rate a bit.
then close the setting menu.
Safe your settings in the folder TMPGenc>Wizzard\
Restart Tmpgenc en with the wizzard you can select your safed settings.
Chose that open your movie.
Do wat it says.
But a a moment you can chose make the file xx% of the cd set it to 100.
Then he wil lower the video bitrate and then the file wile fit on 1vcd.
(If it are 2 files then you can slecet make it 49% of a cd)

The most expediant and simple (and arguably best because you are keeping in spec) way is to simply use 90min discs.

It your total size is 86 minutes at 224Kbps audio, then when you re-encode your audio at 128Kbps, the audio size will be around ~60MB smaller. Every VCD minute is ~10MB, so you new muxed mpeg will be ~80 minutes, which will fit exactly on one 80 minute CD-R. Your MPEG will be 100% VCD compliant because VCD 2.0 specifications allow for audio at 128Kbps.
Actually audio can be 128, 192, or 224 when VCD 2.0 specs are used.

Thks for all the replies.

Now i know what to do. most probably i would just lower down the audio bitrate to 128kbps (as what kwag advised). as the video is a mpeg-1 file (vcd), i believethat lowering video bitrate would not be a good option.

Thank you for all your help.

Actually, audio is 224 kbit/s stereo ONLY for VCD2.0 in the video sequences / tracks. You will be making an XVCD.

Yep, you're right. What a bummer
Here are the specs for anyone interested: http://www.icdia.org/cdprosupport/encoding/pink/mpeg1_specs.htm

Yeah, VCD2.0 is really quite strict...

Thankfully, SVCD is much more flexible in the specs...

What exactly is meant by "For VCDAV (Trackable MPEG), only224kbit sec is allowed."? What is Trackable MPEG?

[vitualis]

It probably means that the MPEG files you can use as a mpeg sequence (i.e., it will be written as a separate MPEG track on the VCD).

I didn't know there was another way of using stuff on VCDs... So the other bitrates are allowed on some oddball special case video only? What good would that do? I mean, requiring compliant players to do additional bitrates wich are then almost never usable?

[vitualis]

Video can go on a VCD in two ways.
(1) As mpeg sequences / tracks (i.e., the ordinary way)
(2) As segment items (i.e., they go in the segment folder -- generally only used for short video clips for menus as well as mpeg still images).

For mpeg video clips, the audio bitrate is fixed at 224 kbit/s.

However, you can make audio only segment items with different bitrates (I'm not entirely sure of the range).

I think the easiest option is lowering the vbideo bitrate, it will reduce the quality somewhat, but movies are still generally left watchable (especially since you are barely going to have to lower it to save 60 mb). This probably isn't the prefered option, but beggers cant be choosey.

Yeah but I think the VCD standard requires padding of the stream to exactly the 1411.2 kbps final bitrate used by Audio CDs, so that 1x drives can play the result without starting and stopping or repositioning the laser. Thus the capacity of a VCD without menus is always close to (nominal audio length - 40 sec), the 40 secs being the amount of room required for the structure info, and the CD-i playback application. I think even using anything above 650 MB disks is probably, strictly speaking, non standard.
