1.1 Identify the formats used when encoding video

What are video encoding formats?

Video encoding formats are many different methods of optimising digital video files for different platforms, programs and devices etc. There are many different methods of encoding video formats but each is composed into two main parts such as a Codec and a Container.      

The Codec and container specifically stores uncompressed video input which is stored, transmitted and viewed. In Streaming it is important that the encoding format is compatible with the widest range of devices possible so that the stream is available to many users.

Selecting the proper video format depends on three main factors: storage availability, quality of video output, and compatibility with different video players and programs.

How does video encoding work?


Video encoding is the process of turning uncompressed video input into a form that can be stored and played in media and such, for instance when before uploading a video to a website which is accessible to other people's devices you must export/encode the video.

This all depends on what device you use, you will have the option to choose how the quality of the video will look when exporting a video, you can choose what resolution you can use when encoding a video.

A resolution shows rows of lines from top to bottom of a screen with a certain number of pixels, examples are 360p, 480p, 720p or 1080p. It is important to export your video before uploading to ensure that the video will run more smoothly and will not lag, so once exported in your files it will be rendered properly and will be ready to upload to another platform such as Youtube and you can upload your video.

Once you are done, you and/or other people can view it from multiple devices like computers, televisions, phones tablets etc.

Video Format Examples: 

MP4: This type of file format compresses audio and video separately, which allows MP4 files to maintain and keep high video quality after compression. Most media browsers and mobile devices such as iOS and Androids are compatible with MP4 files, An MP3 file is similar except it only stores and compresses audio with no video footage. 

AVI: This type of Video format is created by a company named Microsoft. An AVI  is one of the early/oldest Video file container, this works well with a number of different codecs, which can affect the performance of media operating systems and Browsers. It prioritises quality over compression which means that video files are larger and greatly improved in terms of quality overall.

FLV: FLV (Aka Flash Video Format) is a format made by Adobe Flash. The Advantage of FLV is its ability to compress video files without the consequences of losing the overall video quality.

Unfortunately for Adobe Flash it is not Compatible with iOS devices including Smartphones and tablets but however is compatible to other media browsing platforms and Android devices. Browsers have dropped Support for Adobe Flash because it is considered to be insecure, and Adobe no longer supports Flash as of December 31st 2020 (RIP Flash). 

MKV: MKV (Aka Matroska Multimedia Container) is a free open-standard container format which that can hold an Unlimited number of Video, Audio, Picture, or tracks all in one file. It is a universal format for storing media content including Films and TV shows etc. Matroska is similar to other containers such as AVI or MP4, but it is entirely open in specification, with implementations consisting of mostly of open source software.

How to set up a Tripod 1.1: How it is Used,

 A Simple guide of setting up a Tripod Step 1: Start by releasing the tripod legs, in order to do so you must extend the tripod legs, the best method of doing it is to extend from the top down rather than extending from the bottom leg section up. This will help make your tripod more stable that way. Step 2: Release each leg in turn of the height you need. It's better to extend all of the tripod legs to the maximum length rather the getting the height you need for a centre column. Note: only extend the centre column if you need to. As you place your tripod to the ground make sure that once you mount your camera (like a Canon) the leg should be pointing forward and the two side legs should be adjusted so that you will be less likely to knock the tripod during recording. Step 3: Now that you're done, you can now attach the camera to a base plate of the tripod, each tripod will include a baseplate), which clips/clamps the camera into place into the head of the plate...

Evaluation of what I did on Monday 23rd of November 2.1 Planning and Filming,

 What I previously did I have created a visual effect with a spaceship flying using green screen. There is a trick into making this effect, to make it work you will need a prop that looks like a spaceship using invisible thread. To perform the effect first you must set up your green screen, once you've done so you can then get the thread ready and cut it into any length you wish, once you are done you can then tie the tread and connect it to the spaceship, the thread will be hard to notice if the lighting isn't directly pointing to the string. I have created clips of the spaceship using a canon and recorded some clips, once I am happy with what I recorded, I started using Adobe Premiere Pro 2020 and added the clips to my project, once done I have went to google and chosen an image, the one I selected will be the background for the clip. Here is an example of what i have done:

How to use a Camera (Canon) 1.1: How it is Used,

Using a Camera (Canon)  Step 1: To turn the camera on there is an on and off switch on the top right end above on the camera, flick the switch up if you want the camera switched on or flick the switch down if you wish to switch it off. Also take the cover off the lens so you can see what’s displayed on the screen. Step 2: look at the Icons on the top of your camera, you can twist them left or right to select different modes, though personally it’s easier if you just use the regular photo and video mode since they are simple and are one of the most common uses in many movie projects. Step 3: make sure you adjust the camera lens so it will help with focus by twisting it left or right, Behind the lenses you can twist the stick as well to help zoom in and out, or you can press the + button with the magnifying glass symbol. Press the + button a few times and it will zoom back out.  Step 4: You can press the camera icon button once if you are taking a photo, you can press the camera...
