How do I change bitrate for VCD

[martinwbeal]

I want to make a VCD but the length is to long how do I change the bitrate so it will fit (video is about 1 1/2 hours)

Use a program like tmpgenc and use the "unlock" template so you can change the bitrate.

However it will be a "xvcd" thus a nonstandard vcd that will have limited compatibility (not all players may play it correctly).

you can't. vcd is by definition cbr.

I believe the VCD specs allow for less than 1150bps so it is possible to lower it and still be VCD. For 90 minutes it would be around 790, which probably will become unwatchable, but it might be worth a try.

Keep in mind that you can also affect the audio bitrate. Should save you some megs for picture quality. Approximately 1:18 to 1:19 min can fit on VCD. There was that javascript calculator somewhere on this website which could help you greatly with this.

I think your outcome MPG should be something like 810 Mb to fit on VCD or I think absolute limit in some cases is 797 Mb (strange when one file is present I think it can go up to 806 Mb or something like that, but if you have more files (like music videos) then I think 797 is absolute limit).

Give it some testing.

As a recomendation if you decide to give your audio 96 kbps what I would try doing before hand is to "maybe" use Cool Edit Pro or whatever tool you have to pre-filter the higher frequencies or just simply squash them so you don't have that Shivery effect of audio during playback.

For example anything above 16000 or 18000 Hz squash it down a bit to lose some treble. Might help with final outcome of audio quality.

Lastly Tell you what;

Encode your Video with 1050 Video and 128 Audio. I think this should fit on VCD. If you multiplex it afterwards make sure you select non-standard VCD, otherwise file will get bigger.

I have a different suggestion. Do a web search and buy some 90 minute CD-Rs. They don't conform to CD specifications, but they are close enough that just about anything can play them. Many burners can burn these discs. There are also 99 minute CD-Rs, but fewer burners can burn them and playback is more problematic. I have an SVCD I burned a few years ago to a 90 minute CD-R and it plays fine in my DVD players.

if your gonna go with xvcd, you may as well give KVCD a stab as well...at least that route, you will have a bit higher quality output....

Another idea is to try kvcd and the above suggestion.......90/99 min cdr....you can probably squash a full 2 hour movie onto one disc going that route, if you absolutely must have it on one disc....
