A guide to webinar video resolution and qua
lity
In this short read, you’ll learn how to find the video resolution, aspect ratio, and definition quality of your video.
You may not be very familiar with webinar hosting tech, or tech-savvy at all— we understand the struggle. At eboov, we’re dedicated to making hosting on our platform, the smoothest experience possible.
This, of course, means training our clients to be able to independently understand the components of the job.
A question someone might ask is, “What is video resolution?”
Simply put, Video resolution is the number of pixels contained in each frame of an image on a screen.* It determines a few things— how realistic the image appears, the detail, and how clear it is.
Now, it’s important to know how many pixels your equipment outputs.
“A higher number of pixels indicates a higher resolution, and a lower number of pixels makes for a low-resolution video. For the common resolutions of 720 and 1080, the naming convention is based on the total number of pixels running in a vertical line down the display area. ”*
For high resolution, great quality video, you want to look for those high-resolution options. If you host with our platform, eboov there will be no need to worry.
What about Aspect Ratio?
Aspect ratio is the relationship between an object’s width and height— it’s used to describe computer displays, TVs, cameras, and other images.
According to Business Insider, there are several most “commonly” used aspect ratios today, such as how some movies are produced in 16:9, and that aspect ratio has become popular among computer displays as well.*
What is Standard Definition? What does 240p vs 360p vs 480p, refer to?
Standard definition, defined, is the number of pixels on a screen, image, or video. SD images are high-quality images. If the quality of the video is in SD it falls within the 240p – 480-pixel range.*
Remember, the more pixels, the better the image.
What about High Definition: 720p vs 1080p?
Usually, when the resolution gets higher (and more pixels are involved), the image quality becomes sharper and sharper.
The difference:
- 720p has an image resolution of 1280 pixels*
- 1080p has a resolution of 1920 pixels*
Something to note though, is the downfalls of having that greater capacity resolution— it may have trouble with faster moving images, according to Lifewire Tech.
HD and SD video
If you want to stream in HD (that higher definition video) remember, you have to have a certain level of internet bandwidth to sustain it. Graphy.com, tells us you need an upload speed of at least 2.5 Mbps for streaming at 720p resolution.*
“HD streaming requires higher quality as it needs more bandwidth. Whereas SD streaming is the lower quality that needs less bandwidth.”*
What about the 2K and 4k resolutions?
Standard DCI 2K native resolution is 2,048 x 1,080 pixels whereas, DCI 4K resolution is 4,096 x 2,160 pixels.*
HDR vs SDR resolution?
HDR is High Dynamic Range— it’s the extra info, sent along with the video signals, that tell the TV how to display content. It’s top-notch and recommended, if possible.
SDR, or Standard Dynamic Range, is the current standard for most video and cinema displays. The only caveat is that it just doesn’t do what HDR can.
“Unfortunately, it is limited by its ability to only represent a fraction of the dynamic range that HDR is capable of.”*
Shooting Dolby Vision quality video on iPhone 12 or later
Want to try out a fancy video shooting tool? If you have an iPhone model 12 or later, you can make use of the Dolby Vision HDR shooting feature.
The format allows for better light and dark contrast, while keeping the colors vibrant and accurate.
Believe it or not, it’s setting the bar with a higher dynamic range than regular HDR!*
