Television Hertz Ratings

It’s actually a matter of mathematics. American TV is recorded at 30 frames per second whereas films are recorded at 24 frames per second. Since regular TVs display images at 60 frames per second (or 60hz) there is no issue with TV footage because 60hz is divisible with 30fps. That is, you simply show each frame twice.

However, it becomes problematic when viewing films because you can’t divide those 60 frames per second on the TV between those 24 frames per second that make up the film footage. If you show each frame twice then it results in 48 frames per second (12 frames short of the TVs framerate) and if you show it three times then it exceeds the TVs framerate by going up to 72. On a 60hz TV, the only way around this is to have an inconsistent framerate to bring the total to 60 frames per second.

That was the reason why 120hz TVs first started showing up. Because 120 is divisible by both 30fps and 24fps then you can have a proper framerate for both TV and films on a 120hz TV.

But when you introduce 3d into the mix, your 120hz TV goes back to an effective 60hz for each eye. Hence, the only way to get the proper framerate back on a 3d display is by upping the TV to 240hz.

Just note that not all 120hz or 240hz TVs support 3d; it’s simply cheaper for manufacturers to have fewer product lines. While the increased refresh rate can improve smoothness, it’s still artificial and largely depends on taste.

Just read this interesting post on a forum regarding the fundamental reason to buy a 240Hz TV.  This gentleman has to be an Engineer!

The Challenges of 2020

TL;DR: Follow this link.

One of the craziest things about Christianity during the protests of the last few weeks is the fact that there are churches out there not discussing the issues honestly, not taking the time to have the hard conversations, not devoting their Sunday services to betterment of the world and people around them. If you’re church isn’t talking about racism right now, if they don’t mention that black lives matter, instead focusing on platitudes that equate to the all lives matter” sentiment, it is time to start looking for a new church.

My wife and I meet with my home” church virtually via Zoom since the pandemic is still a thing. Kimball Avenue United Church of Christ & La Iglesia Episcopal de Nuestra Señora de las Américas (KANSA, together) combined in a collaborative way to create a single denomination focused on the needs of their community. They follow Christ together toward the vision of love, reconciliation, peace and justice. The justice looks like the demolition and rehabilitation of an old church building and its grounds into a community garden and labyrinth open to all who seek peace through contemplation.

I give this elevator speech to mention that COVID has not been kind to faith communities in general. Budgets have been slashed, funding and grants have been cut, and congregations in need are also working to serve those in need, who are less likely to be able to financially support their church in these times. KANSA in one of the good ones. They speak truth, they have the difficult conversations, they preach in a loud voice every Sunday that black lives matter, that racism has no place in the church, that the LGBTQ community deserves respect and support, and that Jesus was a social justice warrior, who fought for the least of these no matter who they were, where they were from, what they looked like.

In fact, Jesus was most harsh to those who had the means to help and decided not to answer the call.

These systems of oppression we are protesting have been around a long time; they have screwed up a lot of lives, they have been the reason for revolution and the downfall of entire civilizations, they don’t work. We need to find a better way to live by supporting each other. And support has to come in systemic, social, financial, and political ways, both national and local.

I am not local to KANSA anymore, but I support their mission, the way that mission manifests in the world, and the simple fact that they follow Jesus no matter how ostracizing that position can be at times. Which brings me to the point:

Thanks to a $10,000 matching gift’ from an anonymous donor, the challenge has become an opportunity. Over the next two months, we plan to raise at least $10,000 to meet the challenge. Through August 31, 2020, every donation we receive toward our 2020 Challenge” no matter how small or how large will be doubled by the matching gift.

KANSA is hurting financially and needs support, they do good work and are unabashedly progressive in their approach to our world. Donate now and see your contribution matched to keep one of the good ones fighting the good fight.

Thank you for your consideration.
