![]() ![]() However, even if the brain were perfect, there would exist certain limitations that couldn't be beaten. Note that the 1/50 second resolution depends on the neurology – abilities of the eye, nerves, brain etc. So what we see is not "quite" transparent – the contrast is lower – but it's enough to see what's behind the color of the things behind the fan is mixed with the color of the blades and this mixing occurs pretty much independently of the location relatively to the axis of the fan (if the fan blades' color is uniform), and independently of time (because of the averaging over the 1/50 second time intervals). ![]() The weights in the weighted average are determined by the thickness of the fan blades (relatively to the circumference), and these weights may actually depend on the radial coordinate $r$. It's a weighted average of the (RGB) color of the objects behind the fan at the given point and the color of the fan blade. But the averaged color of each point is pretty much the same. If the fan frequency is at least 1 blade per 1/50 second, which is the same as 10 rotations per second for a 5-blade fan, for example, the following is true:ĭuring 1/50 seconds, each point of the image where fan blade may either be or not be sees a full period, so the perception is no different from the perception in which the color is averaged over those 1/50 seconds. That's why 24 or 25 or 30 or 50 frames per second are usually enough for a TV screen. Effectively, the eye may also see the average of $f(t)$ in each period of time which is as short as 1/50 second or so. However, when this function is changing too quickly, the eye can't see the changes. This is a function of time, $f(t)$, for each point. All rights reserved.The eyes are measuring the number of photons of each color that are hitting a given point of the retina – that are coming from some direction.

You can get more information on the Honeycam main page. Please use Honeycam or web browsers like Chrome, Firefox, or Safari to see transparent WebM videos correctly. Please be careful! Most video players do NOT support videos with transparent backgrounds! Even the Windows File Explorer can NOT show transparent WebM correctly. Please be sure to check your WebM video on the system where it will be played because there are some browsers that do not support WebM. VP9 outperforms VP8 on compression ratio but VP8 is more compatible with diverse browsers. You can check how it looks on the browser by clicking the button.įor your information, you can choose VP8 or VP9 for the WebM option. Now just click the Save button and you will have the video with transparent backgrounds!Ĭlick the Save button and select the format as WebM. Please take a look at related topics here. You might want to make your video in a circular shape or with round corners. If you have no images or videos with transparent backgrounds but just with green or blue backgrounds, you can use the Chromakeying filter in Honeycam to make green or blue backgrounds transparent. Just drag & drop a file if it is just one file like an animated GIF, APNG, or WebP. In case you have a lot of PNG or GIF images, please check this page for help. First, open images with transparent backgrounds. ![]() With Honeycam, it's so easy to make a video with a transparent background. Since WebM is a video format, you can create any video you want with a smaller size than image files. Try making a video with a transparent background using Honeycam. You can find more information about WebM here. You might think it's not possible but there's a perfect solution for it. You can make images with transparent backgrounds using GIF, PNG, or WebP but how about a video with a transparent background? Sorry, your browser does not support webm. ![]()
