You are entering the multimedia industry and have hired video editing services. You sometimes do not understand what the editor is conveying because of the niche-specific jargon. Or the video is not to your content but unable to communicate freely. So let's go through some of the basics of the services you are acquiring.
Aspect ratio:
It is the dimensions of your video, the ratio of width: height. Commonly used ratios are 16:9, 4:3, 1.85:1. These ratios are related to certain quality types of videos. For example, high definition wide-screen format is 16:9 whereas, for 4K resolution, ratios used are 1920:1080 or 3840:2160.
B-Roll:
They are supplemental video footages used in addition to the main video. These small pieces of videos give you greater flexibility in the storytelling process. You can use these footages to provide smooth transitions and widen the scope of your narrative with subtle additions. It is also called B-Reel.
Compositing:
It integrates various visual elements in a frame to make it seem that all are part of the same imagery. You can use a video stream, picture, drawing, words, and much more. Anything captured digitally can be composited. It is a fine art and works in layers. For example, many graphics we see in Marvel movies are generated through compositing.
Foley:
It is a process to create or edit sounds effects for video. Various techniques are used to create these sounds are the video is shot. Large production agencies hire foley artists to produce however it is unlikely for any video editing service agencies to produce them. They usually have a collection of foley to use.
Bitrate and Resolution:
Bitrate is the number of bits conveyed per unit time. More the bitrate better the audio and video quality. Bitrate and resolution are proportional to each other. 480p video resolution has 1000 bitrate, and 720p has 1500 bitrate.
L-cut and J-cut:
When the sound of the previous scene continues but vision changes like showing reaction to dialogue or change in a scene during a narration for giving dynamic perception, is L-cut. J-cut is opposite to L-cut. J-cut is audio applied to a preceding scene.
Hard cuts:
It is the most commonly used cut for instant change in the scene without the need for transition. You only place one clip after another.
HDMI:
High Definition Media Interface is a connector device, often cable or card used to transmit the video content from one device into another in an acceptable format that can be played or streamed. There are other devices used as well that perform the same function with varying degrees of efficiency.
Crop Factor:
Crop Factor is the ratio of sensor size to full frame sensor. Sensor size is the dimensions of the sensor in your camera. It indicates the field of vision a camera can capture in comparison to a full frame camera.
Knowing these terms is necessary for the video editing industry.
