Sorenson Spark is an older codec for FLV files but it is also a widely available and compatible one, because it was the first video codec supported in Flash Player. The Flash Video FLV file format supports two versions of a so called 'screenshare' (Screen video) codec which is an encoding format designed for screencasts.

Since stores like iTunes uses this container format, and it is used with iPod and PlayStation Portable (PSP), MP4 files have become more common. The MP4 files (MPEG-4) are the multimedia files which are used with multiple stations and video players simultaneously, they can store video, audio and other suitable amounts of data subtitle even. MP4 file format is an extremely common file format due to its very own container format and it is also used with multiple platforms such as iTunes, PlayStation, and portable PSP as well. |
| Details | MPEG-4 Part 14 or MP4, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital video and digital audio streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. A separate hint track is used to include streaming information in the file. The only official filename extension for MPEG-4 Part 14 files is .mp4. The technical details of MP4 files differ in great aspect and are unique as well, first released in 2001 under ISO/IEX 14496-1:2001 standards, it uses an AAC encoding to wear off unauthorized users from copying the data. The main purpose is the streaming rather than sending video or audio information. MP4 files can be used to store additional data such as text information, subtitles and still images while MPEG format cant do this, anyhow the processing of data into MPEG-4 part 14 requires the use of private streams such as the use of hint tracks to include the information. |
