Best video settings

[Belial]

Hi
just wondering, I want to make a svcd, what are the best parameters for the best video quality....

thanks for any help

The default settings. (If you're an audio freak too, you can raise the audio bitrate to 192 or 224).

Depends on your player. Look at www.vcdhelp.com and find out a base set of values to use. Then make test encodes on tough material and adjust your values to your satisfaction. I spent two weeks testing to get the best baseline to use. Nobody here can tell you what is best for you.

what does the image quality priority mean on the encoding page, at the moment I have this set to 17, but I saw (somewhere on the net) that increasing this value will increase quality..is this true?

About quality and sound: 48->44

I read, that it must not be set. How it show, if player has problem, when it was not converted to 44kHz ? No sound, bad sound, problem in all movie ... ?

Belial leave that at default unless you know what you are doing. Decreasing the number allows more bits to be used at harder parts, but it also increases the file size as well.
Do a search in the CCE forum for more info.

Alexis 44.1 is the SVCD spec and if you have a SVCD only player you will most likely need to downsample. To date there is no known DVD player that cannot play 48 just fine, considering that DVD's are 48 this is no surpise. Downsampling offers no advantage. The filesizes are exactly the same. I have tested this extensively.

OK. I can use 48kHz and 44kHz too well.

I think, may be trouble, when is player connected to receiver via optical or coaxial (all is in digital) and some receivers dont know 48kHz for audio...

[markrb]

No there is no problem. Like I said DVD's are 48 and no reciever has problems with it. 48 is 48 whether it comes from a DVD or a SVCD.

About 48 versus 44.1.

Of course they are.

You specify which bitrate/second you want, arent you?
The resampling itself is negative for quality but since you have cut off the highest unhearable freq. you have more bits allocated for the sound you hear.

128 kbit/s at 44.1 is better quality than 128 kbit/s at 48.
This does not meen that the sound from the movie is better at 44.1 since you have the resampling that partially destroys the sound.

The end story is probably that you get better sound at 48 just because you skip the resampling.
