Sets how the video is encoded. "Auto" suits most conversions. "Copy" reuses the video as-is, so it is fast and keeps full quality, but only when the output format supports it.
Choose how the video is resized: to a set resolution, or to a different aspect ratio, where the video's width is kept and the height is recalculated to match. Select "No change" to keep the original size.
Sets how many frames per second the output video has. Lowering it reduces file size but makes motion less smooth, and raising it above the source frame rate won't add smoothness. "No change" keeps the source frame rate.
Rotates the video clockwise by the angle you select. Choose "None" to leave it as-is.
Flips the video horizontally or vertically. "No change" leaves it as-is.

WebM (WEBM) is a freely-licensed file container designed for the Web. Specifically, it was designed to be compatible with HTML5, originally. It supports chapters, captions, subtitles, metadata tags, streaming, attachments, 3D codecs, 3D containers, and hardware players. WEBM compresses video streams with VP8 or VP9 codecs, and audio with Vorbis or Opus codecs.

 

How to open a WEBM file?

VLC media player and MPlayer can open WEBM files on any operating system (OS). Other good choices for opening WEBM include Winamp for Microsoft Windows OS, and Elmedia for Mac OS X.

 

Microsoft browsers do not have built-in WebM codecs. Therefore, install the codecs separately. However, most browsers support WEBM files.

Flash Live Video (FLV) is, as the name suggests, a type of Flash video. It is a popular format that delivers high-quality, well-synchronized multimedia content, primarily over the Internet. It is also a media container, and as such, uses codecs to compress file size. FLV uses the open standard ISO/IEC 14496-12:2008, also known as the ISO base media file format, which offers the advantage of flexibility and independence.

 

How to open an FLV file?

By default, FLV opens in Adobe products, namely Animate Creative Cloud (Animate CC) and Flash. It opens best in Adobe Flash version 7 and above. FLV does not support chapters or subtitles, but it does support metadata tags.

 

Since FLV is based on an open standard, it can open in many non-Adobe products. Other programs in which FLV can open include VLC media player, Zoom Player, RealNetworks RealPlayer Cloud, Eltima Elmedia Player, and others.
