Banding and blocking are associated with low bitrates. Bitrate is a key consideration in video encoding. Either it is constant, where you set a value of 2000 kbits, 5600, etc. and Handbrake sticks to it, or variable, where you set a quality rate factor, and Handbrake then adjusts bitrate on the fly to maintain quality X. Variable approaches will provide an average bitrate.

Occasionally DVD sources will compress really inefficiently: no matter how much bitrate you throw at it, the encoded result is substantially worse than source. But typically I've found RF 18-21 does a good job. I use mediainfo to ascertain bitrates and other information.

I pulled these settings from a DVD profile I made. They go in the 'More Settings' box

bframes=16:ref=16:fast-pskip=0:dct-decimate=0:aq-mode=2:aq-strength=1.0:qcomp=0.65:me=umh:me-range=32:psy-rd=0,0:deblock=-3,-3

Care to demonstrate 'looks worse'? Are visual artifacts showing up? Are the sources DVD or BD? What encoding speed is in use? What special parameters are specified (More Settings box) in the video tab?

PMing you shortly

Vendors will use passkey implementations as vectors for lock-in. Guaranteed. Workplaces need to accept BYO.

The elephant in the room is that parental controls development is a total wasteland, and has been for years. There's no money in it. FAMAG is actively hostile to it and phone OEMs haven't got a dog in the race and already contend with razor-thin margins. It's one dimension of a broader political problem of digitization that smarter legislators and politicians have surely noticed by now, which is that unlike human beings, users increasingly don't have any rights or agency worth a damn, and are treated with contempt.

I like that a grassroots movement has remembered that parenting should be at the heart of children's technology access, but I fear such groups' 'useful idiot' value to authoritarian elements up to the same old tricks.

THEY KNOW

SHUT IT DOWN

This write-up articulates the issues from the perspective of a security lecturer. The core issue really is ownership of technology.

https://techrights.org/o/2021/11/29/teaching-cybersecurity/

Whatever the appearance of competition between, say, Apple and Facebook, Big-Tech companies collude to maintain interlocking systems of controls that enforce each others shared values including sabotage of interoperability, security and inviting regulation upon themselves to better keep down smaller competitors. Big-Tech comes with its own value system that it imposes on our culture.

Sean, are you a risktaker by nature?

Oh yes. I once read a pop-up picture story book about giraffes.

Pepper grinders exist so you can make sure you're not at a diner.

The threats are what keep us alert, circumspect and fleet-footed in our use of web technology. Always have done.

I want to view multiple tabs at once, in a split-page view where I can scroll on one tab, then mouse-over to another and start independently scrolling on that one. It's probably the key feature I miss from Vivaldi. Is there some insurmountable obstacle in the engine that prevents implementation, or is it stubborn devs?
