Set output AVC (H.264) encoding profile. The older the target device, the "lower" profile you should set. More info can be found on the wiki.
Set output AVC (H.264) profile level. Leaving this setting in "Auto" will calculate the correct level and is the best choice in most cases. More info can be found on the wiki.
CRF (Constant Rate Factor) defines a constant compression ratio ensuring that every frame gets the number of bits needed to achieve a certain visual quality.

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.

f4v

F4V is a multimedia container format developed by Adobe Systems as an evolution of the Flash Video ecosystem. Introduced in December 2007 with Flash Player 9 Update 3, F4V is based on the ISO base media file format (MPEG-4 Part 14) and was created to support the H.264 video codec and AAC audio within the Adobe Flash platform. Unlike its predecessor FLV, which used a proprietary container structure, F4V adopts the standardized MP4-compatible atom/box architecture, making it more interoperable with other media tools and workflows. The format supports advanced features including high-profile H.264 encoding, multichannel AAC audio, and timed text for subtitles and captions. F4V represented a strategic move to address the growing demand for H.264 content on the web, as the older FLV container could not efficiently package this newer codec. During its peak years, F4V powered much of the high-quality video content delivered through Flash-based streaming platforms and video players on the web. The container supports both progressive download and dynamic streaming delivery, offering content publishers flexible distribution options. While the decline of Flash Player in favor of HTML5 video has reduced the creation of new F4V content, the MP4-based structure means the contained media streams are readily accessible through modern tools.
