how to create lowbit rate DVD-R

[klinsi]

Here's my goal:
I want to transfer my collection of soccer tapes to DVD-R. most of this tape recorded in EP mode, so I dont want to waste bitrate and try to put at least 3hours of action to single DVD-R, more if possible.
I captured the video using PowerVCR II 3.0.
I want the output DVD-R to be playable in most DVD player if possible.

The problem:
Seems like no authoring program allows me to do this. I've tried Sonic MyDVD, Ulead MovieFactory and Cyberlink PowerDirector Pro. All of them re-encodes the video to a higher bit rate before burning it to DVD-R.
After re-encoding it usually only gives me about 2 hours of space for a single DVD.

anyone know how to solve this problem?

I've done a similar thing (albeit with material that was slightly more a shade of blue rather than your green ).

I used TMPGenc to set the resolution to 720x576 and audio to 48k. (This is obviously for PAL) A constant bit rate of around 2200 seemed to give reasonable results. 3 Hours plus on a 4.7.

Squirt these into Spruceup, create a few menu's and burn.


Hope that helps .... Cheers.

That's absolutely right.

Encode on TMPEnc at a low bitrate and use it with Spruceup.

You can even encode it at vcd resolution. Just remember audio must be 48KHz sampled.

That way I have put 6 hours of anime TV shows into a single DVD-R.

I have put tho movies on one DVD-R each was 2+ hours in length, have also put three movies on DVD-R 90, 88 min, and 96 min using DVDiT bitrate was 192 Dual Digital setting in DVDiT, I used the KDVD Half template with TEMPGnc to convert with the KDVD tempaltes (352x480 48Hz) which is based on SVCD format. Enven set up menu selections with backgraound on the first screen. Played back on Pioneer DV 343, Panasonic LV55, Panasonic E20, and Samsung M301 with out any problems. I would suggest you visit www.kvcd.net for additional information

I don't understand the need for CBR. Why wouldn't you just use VBR around 2k and have the max extend to 3kb/s. This would essentially allow you to fit 3 hours per DVD, however the quality (or rather, efficiency of bits used) would be much better.

The only reason why I bring this up is that in my first test phases of copying DVDs (err "backing them up"), I used a CBR for my trans-encode, and while a few of the DVDs turned out just fine, a few had macroblocks (artifacting). I did some research and it seems this is attributed to CBR, because if a scene needs more than your CBR allows, it tries to compress (ie "squish") the scene to meet the required CBR. However if the scene bitrate is very high, a macroblock occurs, because there is just too much to compress. When I switched to VBR, this problem ceased, and I will never use CBR again. Not to mention that VBR is more efficient (note: not always smaller in size, just more efficient!) on how much space the video requires.

my .02 cents,

k.

oh, btw, I just ordered my next batch of DVD-Rs, Ritek brand, for about 1.29 USD a piece at supermediastore.com .. will let you know how they turn out.

fand,

Yes you are right. If you have the time to do VBR properly, i.e. let tmpgenc do two complete passes to work out where to use the bandwidth, then you end up with better results.
