Rendering and Conforming Long-GOP MPEG-2 Media

Before you can output or export a native HDV sequence, Final Cut Pro needs to process your media in two ways:

åRender any applied transitions and effects, as well as any leader and trailer elements included in the Print to Video dialog.

åConform any noncompliant GOPs to the correct I-, P-, and B-frame pattern. Any segments of your sequence that contain cuts, transitions, or other applied effects must be conformed to standard MPEG-2 GOP structures before output, creating new I-frames and GOP boundaries where necessary. Conforming also ensures that your HDV sequence has the proper data rate for the HDV format you are outputting. The time required for conforming depends on the number of edits and effects in

your sequence.

Note: Because HDV, XDCAM HD, and XDCAM EX constant bit rate (CBR) footage use an identical format, the information in this section also applies when rendering XDCAM HD and XDCAM EX footage.

Rendering HDV

When you render segments of an HDV sequence, you can choose to create render files using either:

åNative MPEG-2 HDV

åThe Apple ProRes 422 codec

To choose the render file format in an HDV sequence:

1Select your sequence in the Browser or Timeline.

2Choose Sequence > Settings, then click the Render Control tab.

3From the Codec pop-up menu, choose one of the following options:

åSame as Sequence Codec: This option enables rendering with the native HDV codec of your sequence.

åApple ProRes 422 Codec: This option enables rendering with the Apple ProRes 422 codec.

Creating Render Files Using Native MPEG-2 HDV

Rendering native MPEG-2 HDV takes longer than rendering other formats because of the interframe compression this format uses. The advantages to rendering natively are:

åConforming and rendering for export or output to HDV tape happens faster because the render files are already in the necessary format. If you aren’t outputting to an HDV format, this may not be an advantage.

åNative HDV render files are smaller than those generated by other HD I-frame-only codecs.

However, if native rendering is slowing down the pace of your editing, you can choose to render using the Apple ProRes 422 codec.

Chapter 1 Working with HDV

6 specifications

The Apple iPhone 6, released in September 2014, marked a significant evolution in Apple's smartphone lineup. This model introduced a larger screen and a sleeker design, setting the stage for future devices in the iPhone series.

One of the most notable features of the iPhone 6 was its display. With a 4.7-inch Retina HD screen, the iPhone 6 offered a resolution of 1334 x 750 pixels, delivering vibrant colors and sharp images. This screen size was a departure from previous models, appealing to users who favored larger displays for better viewing experiences, whether for gaming, watching videos, or browsing the web.

The design of the iPhone 6 was another highlight. It featured a slim, curved aluminum body that not only made it more aesthetically pleasing but also improved its ergonomics. Weighing just 129 grams, the phone was light yet robust. The placement of volume buttons, the power button, and the headphone jack was thoughtfully designed to enhance usability.

Under the hood, the iPhone 6 was powered by the A8 chip, a 64-bit dual-core processor that offered impressive performance and energy efficiency. Coupled with the M8 motion coprocessor, the device could effectively handle demanding apps and services while optimizing battery life, providing users with a smooth experience throughout the day.

The camera capabilities of the iPhone 6 were also advanced for its time. It featured an 8-megapixel rear camera with optical image stabilization and a f/2.2 aperture, allowing for clearer low-light photography. The front-facing camera was improved as well, offering a 1.2-megapixel resolution and support for 720p HD video, making it great for selfies and video calls.

Connectivity options included LTE support, enabling faster download speeds, and Wi-Fi calling, which allowed users to make calls over Wi-Fi networks, enhancing communication in areas with poor cellular coverage. The iPhone 6 also introduced the Apple Pay feature, allowing users to make secure transactions using their devices.

In terms of software, the iPhone 6 originally came with iOS 8, which boasted new features such as HealthKit and HomeKit, further integrating technology into daily life. Regular software updates ensured that users could enjoy the latest features and security enhancements well into the device's lifecycle.

Overall, the iPhone 6 distinguished itself with a combination of innovative design, powerful performance, and a user-friendly experience, solidifying Apple's position in the smartphone market and paving the way for future iterations in the iPhone lineup.
