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.

3gp

3GP is a multimedia container format defined by the 3rd Generation Partnership Project as the standard media format for 3G mobile services. Based on the ISO base media file format (MPEG-4 Part 12), it was designed to reduce storage and bandwidth requirements so that mobile phones with limited capabilities could efficiently capture, store, and play video content. The format typically uses H.263 or H.264 video codecs paired with AMR-NB, AMR-WB, or AAC audio. 3GP was instrumental in bringing multimedia to mobile devices during the early smartphone era, when network speeds and device hardware imposed tight constraints on file sizes. The streamlined container strips away overhead found in full MP4 files, resulting in significantly smaller files that stream reliably over slow 3G connections. 3GP supports both GSM and UMTS network protocols and includes provisions for timed text and still images within the container. Broad adoption by major handset manufacturers ensured that practically every 3G-capable phone could handle 3GP media natively. Although modern mobile devices now favor MP4 and other advanced formats, 3GP files are still encountered in archives of older mobile recordings and in regions where bandwidth-efficient video delivery remains important.

asf

ASF (Advanced Systems Format) is a proprietary digital media container developed by Microsoft to support streaming over networks. Introduced in 1996, it was originally called Active Streaming Format and later renamed to Advanced Streaming Format before receiving its current name. ASF serves as the underlying container for Windows Media Audio (WMA) and Windows Media Video (WMV) content, though it can accommodate data from any codec. The format was architected with network delivery in mind, incorporating features such as forward error correction, scalable bit rate support, and the ability to seek within streams without downloading the entire file. ASF files include a header object containing metadata, a data object holding the actual media content, and optional index objects that enable efficient random access. One key advantage is built-in support for digital rights management, which made ASF a popular choice for commercial content distribution during the early days of online media. The container handles multiple synchronized streams, including video, audio, script commands, and metadata markers. While ASF has been largely superseded by more modern containers in many use cases, it remains relevant in legacy Windows media ecosystems and enterprise environments that rely on Windows Media Services infrastructure.
