Controlling video playback speed has become an essential tool in modern education (and not only), allowing learners to customize their viewing experience. With advanced tools like Saima, students, and professionals can optimize their video consumption for better comprehension and efficiency.
As advocates of online learning and AI-based tools, we investigated the role of video playback speed in education and some exciting information.
What is Playback Speed?
Playback speed is the rate at which video content is played back. All modern video players have built-in playback speed controllers to make videos faster or slower but they all offer the same speed control options. Tools like Saima offer a more tailored viewing experience with wider options for playback speed. We will talk about Siam’s features later, for now, let’s focus on the general concept of playback speed.
How Does Video Playback Speed Affect Learning?
Numerous studies have examined the impact of video playback speed on learning, providing valuable insights into its benefits and limitations.
Research Findings
According to a study published in Applied Cognitive Psychology, playback speed can positively influence learning when used strategically. Researchers, including Dillan Morphy, conducted experiments with 231 UCLA undergraduate students, who watched videos at various speeds (normal, 1.5x, 2x, and 2.5x).
During the first stage, the team assigned 231 participants to watch two YouTube videos about real estate appraisals and about the Roman Empire. They watched videos at normal speed, 1.5x speed, 2x speed, and 2.5x speed. Students were not allowed to take notes or pause the videos. After watching each of the videos, participants took tests that were repeated after a week.
The findings showed that participants in 1.5x and 2x groups performed similarly well on the test compared to those who watched the videos at normal speed. These results refer to both tests taken immediately and a week later. Learning impairment only occurred when the speed was set at 2.5x.
Another survey among UCLA students revealed that 85% watched pre-recorded lectures at faster speeds, with 91% finding 1.5x speed more efficient for learning than 2x or 2.5x. This suggests that as long as the material is comprehensible, speed acceleration is beneficial.
Interestingly, students could reduce lecture time by watching videos at 2x speed and perform better by re-watching at this speed right before a test. Timing is crucial, as re-watching immediately before a test proved advantageous (source).
In other words, a student could reduce the time spent on lectures by simply watching videos at 2x speed. Alternatively, based on findings from other studies reported in the paper, they could watch a video at 2x speed of the normal pace twice and perform better on a test compared to watching it only once at the regular pace. However, note that the timing is important. There was an advantage only for those who re-watched the 2x speed video immediately before the test, rather than right after their first viewing.
These findings provide valuable insights for students studying at universities in the United States. In general, a midterm exam in colleges covers the content of 10 hours long lecture videos. In this case, a student might consider viewing them at double speed when they are first released and rewatching them at 2x speed right before the exam starts. However, it should be highlighted that the study only examined one-week intervals between watching the videos and taking tests. Thus, further research would be required to explore different time frames.
This research clearly shows that as long as the speed remains within a 2x increase, it is not only a reasonable option but also quite a beneficial practice.
If Saima existed during the research, the results could have been more precise, because Saima offers more flexibility when choosing the ideal playback speed.

Common Misconceptions About Adjusting Playback Speed
There are several major myths and misconceptions about adjusting playback speed. Many of these misinterpretations are the result of a lack of familiarity with the advanced technology. Here are some of the typical misconceptions about playback speed.
Misconception 1: Audio Distortion
One common misconception is that increasing playback speed will result in audio distortion, making it difficult to understand the content. This belief is often rooted in the psychological principle of auditory processing, where the brain expects a certain pace and pitch for natural comprehension.
Reality: Modern video playback tools, including Saima, use sophisticated algorithms to adjust playback speed without distorting audio. These tools maintain the pitch of the speaker's voice, ensuring clarity and comprehension even at higher speeds. This is achieved by preserving the natural frequency of the audio, which prevents the chipmunk-like effect often associated with older, less advanced speed control technologies.
Misconception 2: Loss of Quality
Another misconception is that increasing playback speed leads to a loss of video quality. This stems from a cognitive bias where individuals associate faster speeds with reduced detail and information loss.
Reality: High-quality playback tools ensure that video resolution and detail are preserved even at higher speeds. Saima, for instance, maintains the visual integrity of videos, ensuring that learners do not miss any critical information. The brain's visual processing capabilities can handle faster visual input if the information is presented clearly and without loss of detail.
Misconception 3: Limited Applicability
There is a belief that playback speed adjustment is only useful for specific types of content, such as lectures or tutorials, and not for other forms of media. This is influenced by the cognitive bias of familiarity, where individuals prefer to stick to conventional methods they are accustomed to.
Reality: Playback speed adjustment is versatile and applicable to a wide range of content, from educational videos to corporate training and beyond. Saima's AI-driven approach tailors the speed to the viewer's comprehension level, making it beneficial for various learning contexts. This adaptability can break the mental barrier of familiarity, encouraging users to explore new and efficient ways of consuming content.
Misconception 4: Cognitive Overload
Some believe that watching videos at higher speeds can overwhelm the brain, leading to cognitive overload. This stems from the fear of overloading the working memory, a common concern in cognitive psychology.
Reality: Research shows that the brain can adapt to increased playback speeds without experiencing cognitive overload, as long as the speed remains within a reasonable range (typically up to 2x). Tools like Saima help manage the cognitive load by gradually increasing speed and optimizing pauses, ensuring that viewers can process information effectively without feeling overwhelmed. This gradual adjustment helps the brain acclimate to faster processing, enhancing learning efficiency.
Misconception 5: Reduced Engagement
Another common misconception is that faster playback speeds reduce viewer engagement, as users might feel rushed and less connected to the content. This belief is tied to the psychological concept of flow, where individuals achieve optimal engagement when they are fully immersed in an activity.
Reality: Properly adjusted playback speeds can actually enhance engagement by keeping the brain stimulated and focused. Saima’s Speed Booster feature incrementally increases speed, maintaining viewer interest and preventing boredom. By eliminating unnecessary pauses and redundancies, viewers remain engaged and attentive, promoting a deeper connection with the material.
Conclusion
When dealing with video playback speed, there is no universal truth. However, research shows that increasing playback speed can positively influence learning experiences and outcomes. Tools like Saima provide a personalized approach to video consumption, making learning more efficient and effective.
