As a novice editor, the journey of video making may seem overwhelming. There are millions of seasoned professionals who create high-quality videos. In the initial days, competing with them may seem like an unimaginable task. However, in the world of video creation, authenticity and creativity are the two most important assets. If you can tell your story uniquely and engagingly, the audience will notice your videos.

The journey to creating such exemplary videos begins with preparing a detailed storyboard. You then choose an appropriate online video maker tool and bring your videos to life. While the initial days of video making may seem challenging, here are some tips that will simplify the process.

Plan Your Project in Advance

While planning is necessary for all video editors, beginners must pay special attention to this step. Start by outlining the goal where you spell out the things you wish to achieve from the video. For example, a video that aims to teach an industry concept to the audience will have a different editing flow than one that intends to boost sales.

Then, identify your target demographics and plan a script. The tone of the video editing and other details will vary depending on the target audience. You must realize that the emotional aspect of a video is what drives the viewers to act on your CTA. Focus on leveraging the power of emotions in your video preparation.

Decide on the Background

Once you have the basic layout planned, the next step is choosing the background. Conventionally, most videos were shot in real backgrounds such as offices, living rooms, or landscapes. If you plan to use a natural background, make sure that you check out the location and ensure things are in place before the day of the actual shoot.

Fake background includes paper cut-outs, curtains, green screens, etc. While these are challenging to set up, they go a long way in ensuring consistency of footage. The background of a video plays an important role in conveying the video message, and you cannot afford to ignore it.

Avoid an Expensive Camera

It may seem tempting to pull in all your resources and invest in a high-quality DSLR. Avoid the temptation and restrict yourself to the camera that you own. These days, most iPhones and Android devices are capable of recording clips in 4K quality. These should suffice for all types of basic video making. As you create more videos, you will figure out your device requirements and eventually upgrade your devices.

Do Not Use the Camera’s Mic

The audio of a clip has a drastic impact on the video. While most cameras have a built-in mic, try to avoid using that. Most camera mics capture the background noise while filming. It is a challenge to remove such noise at the post-production stage.

An external dedicated recording device may be attached to the subjects’ clothes. That way, the device will pick up the person’s voice and ignore the miscellaneous sounds such as heavy breathing, the sound of jewelry, fabric rubbing against each other, etc. Alternatively, you can use a boom mic for the audio recording.

Irrespective of the type of mic that you choose, make sure that you test the sound setup. This will help you avoid last-minute confusion and record high-quality clips.

Shoot in Appropriate Lighting

Lighting is one of the most important factors of a video production unit. The type of video and your available budget will dictate the type of lighting. Natural lighting is a viable option for filming and photography. To get soft and cinematic lighting, you can film your clips in the golden hour.

When you record an hour after sunrise or an hour before sunset, you can avoid harsh light hitting your subject’s face. That way, they will not squint, and you can expect high-quality recordings. Alternatively, shooting outdoors on a cloudy day is another effective way of leveraging natural lighting.

If your video demands indoor shoots, the film under bright lights such as ceiling or table lamps. Alternatively, you can pick a room with multiple windows that gets ample natural light. Avoid mixing light of different temperatures and do not use a combination of natural and artificial lighting.

Film in Small Parts

Filming in small segments helps to cut down on the effort required at recording and post-production. As a novice, it might be challenging for you to remember the shot calls, lighting, script layout, and other filming details. When you segment the video into multiple smaller scripts, you will have fewer things to remember. If things do not go your way, there will be more chances to reshoot the clips.

When you shoot in small segments, there is better flexibility at the editing stage. With stabilization and auto-correction features available in most editing tools, the amalgamation of such clips will not come off choppy. Moreover, having short clips gives you videos and sound bytes that can be incorporated in samples and trailers without compromising the message of the video.

Adhere to the Composition Rules

The composition of a video helps in framing the subject in the best possible manner. Knowing the rules of composition will give your video a professional touch. Start by paying attention to the position of the subject’s head. Ideally, there should not be too much space above the head. However, you cannot afford to cut off the top portion of their head either.

While filming, draw two parallel horizontal and two vertical lines such that a 3X3 grid is created. The four intersection points that you see are the ideal places for your subject’s frame placement.

Closeups are an efficient way to improve the dramatic appeal of your content. If you need to cut off a certain portion of the subject’s face, let it be the top of the head. Cutting off the chin will make your videos come off as amateurish.

Distribute Your Video

As a beginner, you may feel that your edited video is not good enough for the world. Understand that the key to creating exceptional video content is getting started on the journey. Irrespective of whether you are creating educational, entertaining, or promotional videos, do not hide them from the world.

You can post the edited videos on social media platforms like Twitter, Instagram, or Facebook. The videos can also go as targeted videos on YouTube. As your videos get popular, you can launch a dedicated video website or have video content on the landing page of your website.

With the above steps, you are now well-equipped to begin your video adventure. As you get to the journey of creating visually appealing content, here’s wishing you an enjoyable ride ahead.

Generative AI, instead of copying or recognising predefined patterns based upon rules, uses complex algorithms based often on neural networks to create original content.

These developments have been made possible by the huge advances in machine learning, a branch of AI which involves teaching computers how to learn using data. Data collection, model-training, learning from data, examining model output, and adjusting parameters are all part of this process. The development of neural networks, a type of computational training model inspired by the brain, has been made possible through machine learning. These models are built from interconnected virtual “neurons” that are organized into “layers” to process data. This system allows a model to be taught how to balance different parameters in order to recognise patterns and learn them, as well as make predictions and complete tasks. Deep learning is another name for this subset of machine-learning.

Deep learning focuses on training artificial neural networks with multiple layers to represent complex data. The term ‘deep’ refers to the depth of the neural network, meaning the many layers of inputs or outputs. This system has been highly successful in solving tasks like image recognition (recognising images/faces/patterns), natural language processing (ChatGPT-like models which can understand and generate human-like responses, most often used to power chatbots) and speech recognition (used for voice assistants or transcribing speech to text) among others.

BLDC Motor Controller Design Principles

Published

7 months ago

April 25, 2024

sylvia J

BLDC (Brushless DC) motors are widely used in various applications, from consumer electronics and appliances to automotive and industrial systems. To control the speed and direction of BLDC motors, specialized motor controllers are required. At Integra Sources, we specialize in designing custom BLDC motor controllers that meet the unique requirements of our clients’ applications.

What Is a BLDC Motor Controller?

A BLDC motor controller is an electronic device that controls the speed, direction, and torque of a BLDC motor. It consists of a microcontroller or digital signal processor (DSP) that generates the control signals for the motor’s power electronics, including the power transistors or MOSFETs. The BLDC motor controller also includes feedback sensors, such as Hall effect sensors or encoders, to provide feedback on the motor’s speed and position.

Key Design Principles of BLDC Motor Controllers

Sensorless vs. Sensored Control: BLDC motor controllers can be classified into two main types: sensorless and sensored control. Sensorless control relies on the back electromotive force (EMF) of the motor to determine its speed and position, while sensored control uses external sensors, such as Hall effect sensors or encoders, to provide feedback. The choice between sensorless and sensored control depends on factors such as cost, complexity, and performance requirements.
Commutation Techniques: BLDC motors require electronic commutation to control the timing of the motor’s winding currents. There are several commutation techniques used in BLDC motor controllers, including trapezoidal (six-step) commutation and sinusoidal (vector) commutation. Trapezoidal commutation is simpler and more cost-effective but may result in lower efficiency and torque ripple. Sinusoidal commutation provides smoother and more efficient motor operation but requires more complex control algorithms and hardware.
Control Algorithms: The control algorithm used in a BLDC motor controller determines how the motor’s speed and torque are regulated. Common control algorithms include open-loop control, closed-loop speed control, and closed-loop position control. Open-loop control provides basic speed regulation but does not account for variations in load or motor parameters. Closed-loop control algorithms use feedback from sensors to adjust the motor’s speed and position in real time, providing precise control over the motor’s operation.
PWM (Pulse-Width Modulation) Techniques: PWM is used to control the average voltage applied to the motor windings, thereby controlling bldc motors. There are several PWM techniques used in BLDC motor controllers, including six-step commutation PWM, sinusoidal PWM, and space vector modulation (SVM). These techniques vary in complexity and efficiency, with space vector modulation offering the highest level of control and efficiency.
Overcurrent and Overtemperature Protection: BLDC motor controllers must include protection features to prevent damage to the motor and controller in the event of faults or overloads. Overcurrent protection limits the motor’s current to prevent overheating and damage to the motor windings. Overtemperature protection monitors the temperature of the motor and controller and reduces the motor’s power if it exceeds a safe threshold.
