Once limited to a few college classrooms equipped with dedicated audio and visual equipment, lecture capture technologies have evolved to let instructors record course-related video just about anywhere.
Today many auditoriums and classrooms on college campuses are set up to make lecture capture simple. Nearly all of the audio and visual equipment in these spaces is possible to preset for easy, one-touch (or even zero-touch) lecture recording — enabling teachers to just walk in, press record, and start teaching.
Record from Beginning - to record from the beginning of a presentation When you're ready, select Record and start speaking. To record from a specific slide, go to it, and then select Record. Note: Narration won't record when slide transitions happen so let these play first before you start speaking. List of lectures:: UCI Open.

Frequently, lectures and other online course content are recorded outside of the classroom, too. In most cases, all a teacher needs to record online course materials outside of the classroom is lecture capture software and a laptop with a built-in webcam and microphone, or a mobile device. This is one of the best ways to record college lectures.
While the lecture capture setup outside of a classroom can also be quite simple with select software and apps, there are a few tricks of the trade that can improve the quality of your recordings.
6 Steps for Recording High-Quality, Engaging Lecture Videos
1. Prepare your lecture and slides
Planning your lecture content and preparing slides in advance can help maximize student engagement. Structure your presentation content in order to help your audience retain more of the material, and prune down content in your slides by eliminating anything that duplicates what you are saying in your lecture — use your slides to enhance your key points, not repeat them. Students will be more likely to pay attention to your lecture and watch it all the way through to the end.
2. Download your lecture capture software or app
You'll need to download lecture capture software to your Mac or PC, if you don't have it installed already. And if you plan to use a tablet or smartphone to record digital course material, be sure to download the mobile app, providing your lecture capture software has one.

3. Optimize audio and video quality
Your recording environment will determine any extra equipment or devices you may need to maximize the audio and video in your recording. Choose a quiet, well-lit room or office, and position your webcam so that it records your head and shoulders and sits about eye-level.
In a quiet, well-lit environment, you should get good enough audio and video from the native microphone and camera in your laptop. Some things to watch out for when recording lecture content outside the classroom:
- Backlighting: If there is a lot of light behind you, or you sit in front of a window, you run the risk of looking like a shadow in a webcam video.
- Low lighting: Webcams have small sensors and tend to make video look choppy and grainy in low light.
- Loud fans and other background noise: Air conditioners, machines that hum, computers with loud fans, and even voices from outside the room can compromise the audio in your lecture video.
- Visible clutter behind you: Avoid sitting in front of anything that can be busy or distraction to your viewers. This will ensure they focus on the content in your presentation.
Additional Recording Equipment For Optimizing Video Quality

- External Microphones: Quality audio is of utmost importance when recording a lecture — if students can't hear or understand you, they won't be able to watch the video. To improve audio, you can add a microphone that plugs into your USB port, such as the Blue Snowball USB microphone, the Blue Yeti USB microphone, or the CAD U37 USB condenser microphone.
- Additional Lighting: Making eye contact in your video is necessary to maximize engagement with students. Make sure that your face is visible and lit with soft light from the front. You can simply position a desk lamp or two behind your laptop, or try this DIY studio lighting hack to soften the light on your face.

Lecture Recording on Mobile Devices and Apps
You can also record lectures outside of a classroom with a tablet or smartphone, though these devices are typically more suited for field recordings or showing multiple viewpoints in a demonstration. Follow all of the above setup tips if you are recording with a mobile device and app, but also keep in mind the following:
- Most mobile device cameras have stabilizing technology, but you should considerusing a small tripod or stand if you are recording yourself — it will create a better viewing experience for your students and free up your hands as your present.
- You can add a clip-on mic that plugs into a standard audio jack, such as the Rode smartlav mic, if the sound you are getting from you phone or tablet's built-in microphone sounds garbled or isn't loud enough.
- Maximize the light in the space where you are recording and avoid backlight. Video quality tends to degrade quickly in low-light or when there is backlight, since cameras on mobile devices have small sensors.
4. Record a test video to check the quality of your audio and video
Once you have your lecture materials and recording setup ready to go, record a test video. In this video you can not only practice your presentation, but also check to make sure you are happy with the sound, lighting, and overall video quality.

5. Record and edit with your lecture capture software or app
Load your slides into your lecture capture software, press record and begin your presentation.
Record all the way through without pressing stop in your lecture capture tool until the very end — if you make a mistake, simply stop presenting for a few seconds to leave a silent pause in the recording. This will make it easy to edit out the section you don't want later. Once you've captured your initial recording, you can begin to edit out the sections you don't want in your video.
When you are satisfied with your recording, click upload. Your lecture capture software will process, optimize, and upload your recording to your video library.

6. Share your lecture video to your LMS
As it's uploading, Panopto automatically transcribes every word spoken in your video and uses AI to make everything inside your videos searchable. You can also request 508-compliant captioning right inside Panopto to add human-edited captions to videos. After your lecture capture recording has processed, you can share the link with students or add the video to your learning management system (LMS). And if your lecture capture software includes video analytics, you can even evaluate the effectiveness of your recordings. For example, if you notice that students are dropping off at a certain point, you can re-edit your original video in your lecture capture software to improve the learning experience.

Lecture/screen capture refers to any technology that allows instructors to record a lecture and make it available digitally by placing on the Web for students to watch online before or after class.

- Flipped classrooms
- Course replay
- Distance learning, fully online and blended (hybrid)
- Massive Open Online Courses (MOOCs)
Screen capture technologies can be divided into three categories:
- Do-it-yourself tools. These tools are easy to use. You need at least a microphone, if not a webcam, to use these tools. You also need to download and install them on your computer.
- Enterprise tools. These tools can be used to record a lecture in a classroom environment. These tools can be called as in-class lecture capture. They can provide a useful way for you to record your lectures as you deliver them.
- Recording studies. A room/place that is designed for instructors to come to this recoding studio and record their lectures or presentations. Usually these studios features quality lighting, studio-quality audio, and HD video.
