The codec to encode the video track. Codec "Without reencoding" copies the video stream from the input file into output without re-encoding if possible.
Set the video quality in a VBR mode. Choose "Custom" if you need to set a fixed bitrate (CBR).
Set an output video resolution by selecting one from the predefined set of the most popular resolutions or manually entering a custom resolution.

mkv

MKV (Matroska Video) is an open-standard multimedia container format developed by the Matroska project, which announced the format in December 2002. Named after the Russian matryoshka nesting dolls, the format is built on the Extensible Binary Meta Language (EBML), a simplified binary variant of XML that provides a flexible and forward-compatible structure. MKV can hold virtually unlimited numbers of video, audio, and subtitle tracks within a single file, supporting codecs from H.264 and HEVC to VP9 and AV1 for video, and AAC, FLAC, Opus, and DTS for audio. A standout feature is comprehensive subtitle support, handling formats from simple SRT text to complex ASS styled subtitles and bitmap-based PGS tracks from Blu-ray discs. MKV also supports chapter markers, attachments (such as fonts needed for styled subtitles), and tagging metadata, making it one of the most feature-rich containers available. The open specification) ensures that any developer can implement MKV reading and writing without licensing fees, which has driven widespread adoption across media players, streaming tools, and encoding software. The ability to encapsulate virtually any codec combination in a single, well-organized file has made MKV the preferred container for high-quality video distribution, archival, and personal media libraries.

wmv

WMV (Windows Media Video) is a family of video codecs and associated file format developed by Microsoft, first introduced in 1999 as part of the Windows Media framework. The format encompasses several codec generations, from the original WMV 7 through WMV 9 (also standardized as VC-1 by SMPTE under the 421M specification). WMV files are typically contained within the ASF (Advanced Systems Format) wrapper and use the .wmv extension to indicate video content. WMV 9/VC-1 achieved compression efficiency comparable to early H.264 implementations, delivering good visual quality at moderate bit rates and earning adoption for HD DVD and Blu-ray disc content as an approved codec. The format was deeply integrated into the Windows operating system, Windows Media Player, and server-side streaming infrastructure, making it a natural choice for enterprise media delivery, corporate training videos, and Windows-centric web content throughout the 2000s. WMV supports features including interlaced video, multiple bit rate encoding for adaptive streaming, and digital rights management through Windows Media DRM. The Silverlight platform also used WMV as its primary video format for rich internet applications and streaming services. While the industry has largely moved to H.264 and HEVC for most applications, WMV remains present in legacy enterprise content management systems, archived media libraries, and workflows tied to the Windows Media ecosystem.
