50 Intermediate Codecs compared
One of most often linked pages in video editing tutorials is Compare 50 Intermediate Codecs. This page compares bitrates of several industry standard intermediate codecs: DPX, Cineform, DNxHD, DNxHR, ProRes.
Intermediate codecs are used during editing video. Their advantage over highly compressed codecs like VP9 or H265 is very fast decompression at cost of much larger files.
IEEE-754 storing of floating point numbers
How are floating point numbers stored in computer? To understand how IEEE-754 Floating Point numbers works internally visit IEEE-754 Floating Point Converter.
It can convert floating point numbers from or to their internal binary representation. 32-bit floating point numbers are stored 1 sign bit, 7 bit exponent, 24 bit mantissa.

Video file size calculator
When you are working with professional video formats its always good to know estimated file sizes. Files are pretty big - up to 2 GB/minute for FullHD 1080p 30fps video.
There is pretty nice Omni Video size calculator where you can compute size of most common professional video formats such as AVID, Cineform, DNxHD, ProRes, REDCODE, DVCPROHD. Note that very common DNxHR codec is not included.
Opensource Internet speed test
There are many tests checking your internet speed. Usually these tests are will harvest data from you as much as possible, sell you ads, track you and sell your data to advertising companies.
Libre Speed - Open Source Test
This test is different. Its open source with code available on GitHub. No tracking, no ads. Just a simple test.

How to get libfdk-aac FFmpeg build
FFmppeg by default includes faac AAC encoder/decoder which is not that bad for AAC-LC, but for AAC-HE its bad.
To get better AAC encoder you need libfdk-aac encoder which is included in non-free FFmpeg builds. They can be downloaded from:
Happy AAC encoding!
