View Full Version : Chapters, not using them, save space?

If the option existed to not use chapters would that save any space on the CDR disk?
I am attempting to force as much onto a CDR as possible and want to put a movie on 2 CD's.
If I didn't use chapters would this save any space?

Just so you know I am overburning, but I need to find 2 mb's somewhere and I really don't want to re-encode the video again.

If all else fails I will re-encode the video and drop the bitrate a little.

Chapters are based on the premise of entry points in the disc image. They add no overhead.

So.. no, it would not make your disc smaller to not use them.

re-encode the audio at a smaller bit-rate, it will save you a lot of time as opposed to re-encoding the video

Founder I would have done that in the beginning, but I am already at the lowest audio bitrate I would consider using.
I was able to squeeze it onto the discs as is. I just had to play with the muxing a little.

I kinda figured that about the chapters, but I wasn't sure.

If it is a one-time-only thing, how about getting 90 or 99min CD-Rs? And regarding your other post, I am afraid you can't really cut down on the first track of an SVCD either. Some players might still accept it if you remove part of the directory structure, some wouldn't ...

I would grab some larger CDR disks, but I have about 160 80 minute already. If I can find some that are not too expensive I will give them a shot.
I kinda thought that, but worth a shot anyway.

Thanks,

for heavy compression did you try any "out of the spec" setting.
I use to do PAL conversion to MPEG1 (yes, no MPEG2) VBR, 480x576 with very low average bitrate and the result was not so bad (far better than standard VCD, because of the higher resolution and the VBR thing).
You'll have to check if it works with your standalone player (everything fine with my Pioneer 444).

I write about 82 minutes to my cheap 80 minute CD-r discs....I haven't had a problem thus far and haven't tested the discs to see how much capacity each brand (well, generic-brand) of disc really has. However, this ONLY works if you CD writer does a VERY good job at positioning the laser at the end of the CD-r disc. My LG-8016 16x CD-r drive does and AWSOME job at this, while my SCSI Plextor 12x drive did a very bad job, even at 2x, on anything near then end of the disc (even like 75 mins for example on an 80min disc).

Why not use MPEG2 with the same very low avg bitrate. MPEG1 does not yeald better compression or quality than MPEG2. And the out of spec VBR MPEG1 480x576 is not playable on many standalone.
The only key to save space is using lower bitrate.
By the way, when you want to compress a lot you get better quality with less resolution because there are more bits per compressed pixel.
