KDVD settings

[tonemgub]

I was reading about kdvd on kvcd.net and it said that using the kdvd settings it was possible to create 6hr dvds using full size (Full D1). When I was looking at the kdvd quick setting for the newest ffmpegx it listed the size as Half-DVD, also on the ffmpegx site it says that the kDVD setting gives about 5hrs, so I'm assuming its 5hrs at Half-DVD since thats the default kdvd setting... (according to kvcd.net halfsize kdvds should hold 10hrs)

How can I get the 6 hour full size settings in ffmpegx?

now this is cool
is it compatible to normal dvd players?

[tonemgub]

according to kvcd.net:

Using KVCD parameters to create DVDs (KDVD), will enable you to create 100% DVD compliant MPEG-2 streams, capable of playing on any standard DVD player. This will allow you to put up to about 6 hours Full D-1 720x480 on one DVD, or about 10 hours at Half D-1 352x480.

But once again, does anyone know how to achieve this using ffmpegx? (I want to do the 6 hour full D-1 thing)

You're free to change the video size to 720x480.

tonemgub - You can create 6 hour DVDs right now that are fully compliant by simply using a low enough bit rate. All of the K* formats do various bogus things, mostly by using insane GOP sizes, to jam more video onto a disc than they normally should be able to. The fans of the formats all lie and say "The quality is just as good as a DVD!". You are welcome to try it for yourself, but you will most likely find that you have been mislead about the quality of the video unless you are one of those really really unpicky people that seem to be attracted to KVCD, KDVD, etc. You should be aware that having GOP sizes of more than 15 in PAL format DVD and 18 for NTSC format DVD violate DVD standards and such discs may or may not have playback problems.

I don't know how to use ffmpegx, but I wanted only to warn you that K* quality is not as good as claimed. The reason they use half height is that the bit rate is very low and using half height video covers up the fact that the bit rate is low. However as major said, you're free to use full D1 if you want, but you probably won't like the results.

Hmmm.........I dont know what Kwag done to upset people on this site but it must of been something bad because every time anybody mentions KVCD or KDVD it is slagged off,yet crappy VCD(spot the blocks) is talked about like its some great format.

KDVD uses a quantization matrix which is supposed to increase the compression rate, so you can reduce bitrate and lose less quality than you would lose by not using it. So, it should be used only in case of need to greatly reduce bitrate, eg. of burning a large amount of footage in a single CD or DVD, quality being a secondary issue. I would recommend testing with various settings of size and bitrate to decide if it fits to your needs.

Major's assessment is spot on. KVCD/KDVD is for those who prize compression over quality. I think what puts some people off is Kwag's exaggerated quality claims. Anyone who has actually used his templates will find that quality is indeed sacrificed to enable longer play time. It's just that his tweaks reduce the penalty. And, to quote Martha Stewart, "that's a good thing." I make KVCDs regularly, with the foreknowledge that I'm trading off quality. I get what I expect, so I'm not disappointed.
