The history of video formats is a fascinating technological evolution. The first digital video format, H.120, was standardized in 1984 with a resolution of just 176×144 pixels. Modern formats like H.265 (HEVC) can efficiently compress 8K content that's 275 times larger. Interestingly, video containers (like MP4, MKV, or AVI) and codecs (like H.264 or VP9) serve different purposes—containers are like packages that hold video, audio, and metadata, while codecs are the algorithms that compress the actual video content. This distinction explains why a file can have an MP4 extension but contain video encoded with various codecs.
Video format conversion involves two distinct processes: transcoding and transmuxing. Transcoding re-encodes the video stream using a different codec, which is computationally intensive but necessary when changing between incompatible formats like WebM (VP9) to MP4 (H.264). Transmuxing, or remuxing, simply repackages the existing encoded streams into a different container format without re-encoding, making it much faster when the source and target formats use compatible codecs. The quality impact of conversion depends largely on the bitrate allocation—higher bitrates preserve more detail but create larger files. Modern encoders use psychovisual optimization to prioritize details the human eye can perceive, intelligently discarding imperceptible information to maximize perceived quality.
An online video format converter allows you to quickly change video formats without installing specialized software. It's convenient for ensuring compatibility with different devices and platforms from any device with a browser.
Our converter aims to maintain high quality during format conversion. While some quality reduction can occur during transcoding, we optimize the process to preserve the original video quality as much as possible.
Conversion time depends on the original file size and the target format selected. Most conversions complete within a few minutes.
