STANDARDS FOR VIDEO CREATION AND SELECTION OF A CAMERA
The course created on the platform consists of both video and audio as well and proper sync is required between the two. There are some standards to be followed before the creation of both of these mediums. This article will help you to understand the basic standards that you need to follow before creating video content for your course.
Q1. What should be the standard for video creation?
To upload a video to the platform for effective and clearer learning, the video content must be in HD quality with a resolution of 720p. It can be more than that but this is the minimum resolution required for uploading video on the platform.
Q2. What should be the time duration of a video?
The time duration of a video is very important as very short videos do not lead to effective learning. Hence, on the platform, the duration of the video should be between 25 to 45 minutes.
Q3. How do you select a good-quality camera for content creation?
As mentioned under the quality standards for content creation, it is required to use a good quality camera and a microphone for good quality output of your course.
The video should be filmed in a well-lit environment having no disturbances. For this, choosing a camera of the right type and quality becomes necessary. The camera to be used should certainly have a resolution of 720p or above.
There are no certain restrictions towards using a particular camera, but here are some of the recommended ones to film your course.
iPhone 4 models and above
iPad 2 model and above
HD flip cameras
GoPro and DSLR cameras
OR any camera that can record the video at a resolution of 720 HD or higher.
Any brand or company camera meeting the requirement of this resolution will be considered sufficient and will follow the standard for video creation on the platform.
Q4. What are the Standards and software to be used for shooting screen-recorded videos?
Many times instructors record a screencast video to explain certain concepts related to computer mechanisms or to provide a better demonstrative approach to learning practical content.
Such videos require certain software to be used for editing and designing the videos. Certain software which can be used on different computers is listed below:
For PC or Mac computers Camtasia, Screen, Snagit
For Mac computers iMovie, Screen flow, Quick time can be used For PC only Cam Studio, Microsoft Expression
Q5. What is the recommended file format/codec for video files for exporting to the platform?
The video needs to be recorded and saved in a compatible format that is supported by the platform. These formats can be changed in the editing software you are using for editing and designing your video content.
