Image too big?

He's saying don't grab too much from stealing space and half-halfing.

Do I understand this correctly -

1. I shouldn't use steal space... and half/half at the same time

2. Which is better - and if one is better - why have the other?

3. If the answer is steal space, can I set that to 50%?


Thanks!

Also. from the tutorial you'd think it's ok to use both:


Steal Space from Extras:

* This option allows you to improve your main movie quality by reducing the quality of extras. It works by taking storage space (10%, 25%, 33% or 50%) from whatever is in use by the extra and then reallocating it to the movie.

This reallocation of space happens BEFORE other options - so, for example, if you choose Half-D1/Half-Space and also choose 50% reduction, the Half-D1 size will be halved twice, resulting in a Half-D1/One-Quarter space.

o 00% No Space Stolen (Default)

o 25% (Quality Drop on Extras)

o 33% (Significant Extra Quality Drop)

o 50% (I don't care about Extra quality)

* CAUTION!!! Don't use this option with "Episode" DVDs!!!

jdobbs is recommending against using both as it kills the BR.

In your case, half/half alone should be sufficient (untick steal space from extras or if it is ticked, have it at 0%).

Many folks would not go beyond half D1/25% (since the original was encoded at a low BR to begin with, and it is being compressed in the encode, so another 50% might kill it totally). You really need to figure out the BR of the extras you're trying to encode.

For mine, I watch the extras once (most times). My backups are main movie and menus only.

EDIT: The tutorial is warning you not to use both options simultaneously, cos you end up with quarter the BR. Say you started with the bare minimum - 2000kbps. You'd end up with 500kbps, which is less than half VCR quality. So the tutorial is saying implicitly, don't do both unless you wanna crunch it to oblivion.

Strange - I don't find anywhere where it says not to use both. Also, it certainly doesn't mention that using both will result in an oversized video - maybe we're talking different turorials - I'm looking at the one for dummies...

[blutach]

Maybe it doesn't say so explicitly, but by implication it is saying use it at the risk of ruining the bitrate on the extras.

As for oversized video - this is an anomaly. You now know what to do and not to do.

True that!

More reason for me to get the pro vers., I think, as well - forget the extras all together

[blutach]

I certainly didn't regret going pro. It is outstanding.

My experience:
Half/half plus steal space from extras (e.g. 50%) may result in a bit rate which is unacceptably low for a particular encoder. The encoder may then overwrite the value with its own minimum bitrate which is higher than the quarter bit rate from half/half plus steal 50% from extras. => The result is oversizing

That appears what has happened Sharc. And thanks for the info. And more importantly,
