Tips on creating videos for your virtual events
Videos are a great asset to a webcast – especially if they are interesting and pertinent to your content. It breaks up the presentation, and allows your speakers a little break as well. However, if you are going to incorporate videos into your webcast, there are a few key technical items you should consider first.
You want to make sure that the videos are in the best file format recommended by the webcasting platform that you are using. We typically recommend an .mp4, it’s a pretty universal format on most platforms from WebEx to ON24. You also want to make sure that the files size and bitrate of the video are small enough to play and be consumed by your attendees without causing issues. The best way to do this is to look at the bitrate of your file and compress it down to as small as possible without impacting the quality of the video. What exactly is the bitrate you ask? You’ve probably heard the term but let’s break it down to the different “pieces.”
Bitrate
In all video files, you have the video data, audio data, and “Overhead Container” which has the data about the video and the codec type – these are basically the instructions that a computer would use to play the file. The Bitrate is the number of “bits per second” (bps) at which data in a video is being delivered. The size of the file and the quality of the image and sound are both controlled by the bit rate used. The higher the bit rate, the better the potential quality and the larger the file size. Lower bit rates should be used for international audience or events with a large number of people accessing the webcast from the same network. Higher overall bit rates may be utilized, but when exceeding 800 Kbps, many attendees may experience latency, buffering or playback issues.
Frame Rate
If you are looking at the details of a file, you will also notice a Frame Per second rate or (fps). For low movement videos, such as instructional videos and live webcams, a 15fps frame rate will provide a clear and quality stream to the audience. Higher frame rates are permissible but do consider that 24+ fps is utilized for HD video and broadcast television; 15 fps will greatly reduce the file size without noticeably affecting quality. If a cursor is the only constant motion, 1 fps may be sufficient.
Frame Size
For most webinar platforms, video clips are displayed in the slide viewing area, so to keep things consistent, we recommend matching the video frame size to the same aspect ratio as your slides. So if you are using slides that are 16:9 (widescreen), you would ideally want your video to be 16:9. If your slides are 4:3, then your video frame should also be 4:3 so it fits in the space without being stretched or resized. Dimensions for videos – for 16:9 ratio you would want 640 x 360, 480 x 270 and 320 x 180. For 4:3, you would want 640 x 480, 440 x 330, 400 x 300 and 320 x240 pixels.
Audio Format and Specs
AAC Audio format is preferred if using H.264, with MP3 the mobile stream might encounter issues. 32 Kbps audio is sufficient and will allow the video to be encoded at a higher bit rate. Anything over 96 Kbps for the mono audio stream is superfluous unless the audio was recorded in a studio.
So next time you are creating a video for your webinar or webcast, keep the specifications and tips above in mind to ensure your video will shine without the risk of streaming issues for your attendees. V2 is happy to assist with any file compression or clean up needed to ensure your videos play flawlessly.
In her TED talk, Rebecca Kleinberger discusses her studies on how we use and understand our voice and the voices of others. In her studies she states that changes in the voice can mean many things, from depression, to hormonal changes, to even detecting pregnancy. She describes our three voices – our Outward, Inward, and Inner voices. Our outward voice is the voice we use when we are speaking with others, it’s the sound that others hear. Our Inward voice is the voice we hear as we are speaking, and the two can sound quite different, as our inward voice is being processed through our bone and inner ear. Our inner voice is what we hear when we read something silently, what we hear when we are thinking or dreaming. Though we can’t always control it, we can always engage with our inner voice.
Why is it that we do not like the sound of our outward voice on recordings? Well, as described above, we are used to hearing our inward voice when we speak. So thus, the thought many of us have which is: “Is that really what I sound like?” is because our outward voice is indeed different from our inward voice. Our inward voice travels through our bones (bone conduction), so it will sound deeper and more harmonious, then it travels through our inner ear, and the cochlea which then processes the sound. We find that seasoned speakers are very comfortable with their inward and outward voices. The trick we have found to getting comfortable with your recorded voice is to practice your presentations, and listen to your recording. Your voice is an amazing thing and can be changed in volume and tone with deeper breaths, posture, and breathing exercises. Play with your inward and outward voices until you find a voice that sounds that best for your presentation and audience.

For those new to the virtual world of webinar presentations, virtual stage fright can be a real fear. Although for those who suffer from stage fright, it can ease your fears a bit if you aren’t on camera and are just speaking to slides and demos. However, in my experience the silence and lack of eye contact from live attendees on a webinar can be difficult for even seasoned public speaking professionals. For many, that lack of in person audience acknowledgement can be tough to gauge interaction and interest.
What causes stage fright? The reasons for having stage fright vary from person to person, but commonly those with stage fright lack self-confidence. Some may have anxiety from being unprepared, forgetting their lines, and being negatively judged by their audience. Stage Fright is at its core a physiological response, commonly referred to as “Fight or Flight.” When presented with a stimulus, our reaction is either excitement or fear. This triggers the release of adrenaline, which gives us a huge boost of energy to stay and fight the stimulus or flight – to run away from the stimulus. The classic symptoms of stage fright – stomach pain, shaking, trembling, vomiting and shortness of breath, are the side effects of this burst of adrenaline coursing through our bodies.
Whether you are giving a live presentation or a virtual one, you are probably wondering, how do I overcome my stage fright? We thought we would share a few easy techniques that if practiced can help you quell your anxiety.
- Get your Sweat on! – This may seem counter intuitive, but redirecting the energy causing your stage fright symptoms to exercise can help focus your energy away from your nerves. Try doing your normal exercise routine that morning to help alleviate some stress, and even right before your presentation, try rubbing your hands together really fast to pass on all your nervous energy.
- Just Breathe. Focus on your breath. Breath deeply, and exhale and inhale at least 15 to 25 times. This will help your mind and body relax.
- Practice your Presentation. Practicing and knowing your speech inside and out will help you feel prepared and less anxious about forgetting your lines. Repeat it until you know it by heart without having to look at your notes.
- Eat Healthy. This may seem like another strange one, but the foods you eat can affect your anxiety level. Avoid drinking caffeine prior to your performance as these will only make you more jittery, also avoid that soda so you don’t accidentally burp halfway through your presentation!
- Drink Water. Drink some water before your presentation to avoid your mouth from going dry – however be careful not to drink too much to avoid feeling like you need to go the bathroom while you are speaking.
In his charming TED talk, graphic designer and folk singer-songwriter Joe Kowan talks about how he beat stage fright. He actually wrote a song about stage fright describing exactly how he was feeling while it was happening, and by exploiting his anxiety and allowing the audience to feel it along with him, he was able to overtime, over come it.
We hope you’ve found this article helpful the next time you are confronted with the old “fight” or “flight” stimulus response. You would think that by now, our bodies would recognize the difference between a virtual presentation and a Grizzly Bear. We are here for you and V2 will do whatever we can to easy your anxiety along the way.

Everyone’s lives are busy and packed with a million things to do – whether it be in your personal or professional life. We’ve all heard the term “multi-task” and we all do it, perhaps even on a daily basis. However, we must ask ourselves, how efficient is multi-tasking? Yes, maybe we are accomplishing multiple tasks at once, but how efficient are we completing those tasks? In his TED talk, “Forget Multi-tasking, Try Mono Tasking” Paolo Cardini talks about the busy world in which we live and how technology and endless apps allow us to “multi-task.” You might be cooking dinner, talking to a friend, and trying to send an email all at once, and then you smell something burning right as you are about to hit send. This is the fallacy that can happen when we try to multi-task – something can get forgotten or not done to the best of our abilities. He playfully shows images of our iphones paired down to a single calling function, and a simple “compass” app to bring us back to a simpler time when we focused on one thing at a time.
Planning events, whether in person or in the virtual landscape can be a daunting task, with many facets – from marketing to scheduling to finding speaker talent and narrowing down a topic. Those things take enough of your time without having to focus on all the behind the scenes technology – such as webcast schedule and setup, branding, video compatibility, emails, and reports. That’s where we come in. Let V2 help take care of all the logistics so you don’t have to multi-task when it comes to your event, and you can “mono-task” on one thing at a time. Our mission is to make your life a little less stressful, so you can focus on the message, not the mess-ups.
