About GIF, WebP, and WebM formats

GIF

The GIF format is the most common image file format used on the Internet along with the JPEG and PNG format.

It is a well-supported format by all browsers because a long time passed since its development. Also, GIFs have been used as motion images for banners on websites.

It can also be used as short and small-sized motion images, instead of videos, because GIF can express an animation that includes video-like movement, which is a series of images that endless replay.

GIFs have a 256 colors limit. Therefore, the expression of high-definition images is limited too. So, a lot of animated GIFs created by existing programs suffer from severe image-quality deterioration.

By contrast, Honeycam can create ultra-high-definition animated GIFs that are close to the original video. Honeycam does this by minimizing this undesired effect through optimization and quantization of 256 colors.

WebP

Google developed WebP image format in 2010 to use in the Web instead of existing Jpeg, PNG, and GIF. WebP file is smaller than Jpeg or PNG without loss of image quality.

WebP also supports an animation feature to replace existing Animation GIF. Animation WebP is smaller than Animation GIF by up to 5-10 times.

However, not many browsers and image viewers support this format. As of 2018, only Chrome and Chromium-based browsers(such as Opera) support WebP.

WebM

WebM is a video format developed by Google. It uses VP8 and VP9 video codecs, and its compression efficiency is similar or better than H.264.

Because WebM is not an image format, but a video format, you can play this video file by using the Video tag of HTML5. Unlike WebP, many browsers support WebM; Google Chrome, MS Edge, and Firefox,

Be mindful that Honeycam does not support audio recording with WebM or MP4.
