x264 vs other H.264 encoders.

Disney also gets to encode a lot of animated content, which (if recent) is noise free.

Plus Disney has a lot of respect for their masters these days, and care a lot about presentation quality.

...making up for the era when they'd taken 4:3 (pre-TV) movies, cropped them to 1.85:1 for theatrical re-release, and then pan and scaned THOSE for the VHS release...

Yep- because they do care :)

I wonder if the HD version of Cinema Craft has the filter turned on by default like the SD version...



Yes it does, but low pass filtering at default setting with Cinemacraft HD will remove just a very small amount of the details- it's not going to be realy visible. Default setting in CCE-SP was set relatively way highier.

looking at kung fu panda, its been lowpass filtered in essentialy the same way as most dvd's. This is quite annoying, as most of the time the lowpasses used in such cases don't have a well defined cut-off point (this reduces ringing) which makes it more dificult to clean up the mess.

You have quite big control over cut-off point and also curve shape of the low pass filter. Have a look here:

You can set it up as you wish even differently for Y, Cb and Cr, but the best is to turn it off as long as encode looks good.
Sometimes is good to filter Cb only, becuase it quite often looks bad in case of the source from digital cameras.

Gents, you're way OT now.

Get back on topic or the thread will be closed.

What is "high frequency"?

Is there a comparison pic that shows the difference between a normal frame and a low passed frame?

Can x264 (or any other encoder) low pass an encode?
