But the conversion these days between Stick to This is happening as we speak The codec develped by Cinegy Cinegy Daniel2 is a game changer to the post-prod workflow.

It is a open source codec, ultra eficient, based on GPU image processing witch bring a whole another level in terms of image processing Current GPUs deal, with ease, 8k footage!! This is a massive improvement to all the small production companies, this is a solution that gives the best! Just want to spread the word about this!

I ask the community to embrace the idea of new. If it wasnt for these leaps in technology Choose your information. Be wise about the information you choose. Don't take for granted anything that is put out there without experienced it!

Do you shoot 60fps? What about 3D or VR? Do you find the faster framerates like 60fps offer a better viewing experience? Let us know your thoughts in the comments.

In the early days of broadcast television, huge increases in viewership created demand for more high-quality, standardized television programs. The earliest television sets used cathode ray tube CRT technology to display video feeds as many vertical and horizontal lines, creating the first standard video resolutions. Interlaced video is a standard method where the display first updates all even-numbered lines, then updates the odd-numbered lines.

In true interlaced video, each half-frame displays a static image. This means a ball moving across the screen would be in a different position for each field, or two different positions per frame. In order to synchronize—and therefore standardize—frame rates for each television set, early systems used the AC power system.

The American power grid is a 60 Hz system, which created a standard broadcast television frame rate of 30 fps. In Europe and other places with 50 Hz power systems, television broadcasts use a standard frame rate of 25 fps. With the addition of color television came new challenges.

Standard black and white television signals, known as luminance signals, could be broadcast without issue. Building off earlier research, industry leaders developed a system where chrominance information could be encoded into the same signal as luminance information. While this would display color on compatible devices, chrominance information often interfered with the luminance, creating visible dots on non-compatible black and white televisions. By adjusting the standard television frame rate, the dots would no longer display in the same place on the screen each second.

The dots were far less noticeable when they were moving around. For this reason, the standard broadcast frame rate in the United States is approximately This history is the reason we have so many standards for frame rates and video formats. Because Video playback that is slightly too slow or too fast is usually imperceptible, except when synchronizing audio.

If a video is two hours long and was recorded at 30 fps, the video contains , static images. If that video is played back at
