DVX200 Bitrate

I’m not a fan of the small Micro Four Thirds sensor size (yet I put my preorder in for the Blackmagic Pocket Cinema Camera 4K which is just that) but still the Panasonic DVX200 is quite the capable camera. Looking a couple of years back, this was and pretty much still is the cheapest fixed lens video camera that supports 4K60p. With a constant f/2.8 aperture throughout the zoom, you’d be very and I mean very hard pressed to find an interchangeable lens camera + 13x zoom lens combo at the $3.5K price point.

Here’s a quick rundown of the internal bitrates:

2160p59.94 = 18.75MB/s = 1.125GB/m = 67.5GB/h

1080p59.94 = 12.5MB/s = 0.75GB/m = 45GB/h

YouTube 120fps

And no I do not mean 120fps played back at 24fps for a slow motion effect. I’m talking about 2160p120 played back at 120Hz for an ultra smooth look just like the UI of the 120Hz iPad Pro.

Yes I could of uploaded to YouTube at 120fps a long time ago since the URSA Mini 4K supports 1080p120 in up to ProRes HQ, but who wants HD when you can have 4K120? Good thing the RED Raven supports just that!

and after uploading to YouTube… the video frame rate is downsampled to 60p. Darn. But hey at least YouTube correctly removes every other frame instead of slowing down the video by 50%.

Until next time.

Python 3.7.1 Dictionaries

Dictionaries are kind of like lists and tuples but, instead of using index numbers, they use keys to point to values.

numbers = {"one": "un",

   “two”: “deux”}

print(numbers)

CONSOLE OUTPUT

{'one': 'un', 'two': 'deux'}

In order to create a dictionary, we enclose pairs of keys and values in braces and assign them to a variable.

Unlike the index numbers of lists and tuples, keys can be any type.

numbers = {"one": "un",

   "two": "deux"}

numbers “three” = “trois”

numbers[True] = “quatre”

print(numbers)

CONSOLE OUTPUT

{‘one’: ‘un’, ‘two’: ‘deux’, 3: ‘trois’, True: ‘quatre’}

Even boolean values are used as keys.

But how can we get to the values in a dictionary?

n = {"one": "un", "two": "deux"}

print (n[“one”])

CONSOLE OUTPUT

un

Kind of how we add values to dictionaries, we put a key in a pair of brackets to access the value that it points to.
