Constant Quality (CRF): CRF sets up a constant compression ratio in a way that every frame gets the number of bits needed to achieve a certain perceptual quality.

Resize: Set an output video resolution by selecting one from the predefined set of the most popular resolutions or manually entering a custom resolution.

Frame rate: This option controls the number of frames per second. It changes the playback smoothness only, not the output video duration or video playback speed.

Advanced Systems Format

ASF is a media container used by Microsoft Windows Media Player. It was designed for streaming audio and video files online. The container determines the structure of the data stream but not how the data should be encoded. Usually the files encoded by Microsoft developers have the .wma or .wmv extensions, other files have .asf extension. Such files generally have MIME type that allows sending files via the internet. The main feature of the ASF is the ability to stream playback, that is the ability to play a video or audio directly at the time of downloading data over the network.

HEVC Converter

High Efficiency Video Coding

HEVC or h.265 is the most advanced codec for now because it has the lowest bitrate without losing the image quality. The codec has three main features that distinguishes it from others: parallel decoding, random access to images within the video stream and larger maximum block size. HEVC is aimed to offer the same level of video quality as AVC (h.264), but with improved compression, that is why a video file compressed with the codec will be twice smaller.
