Convert H261 to MP4

H261 to MP4 software converts H261 to MP4 with high quality and fast speed. With a simple user interface, the software is very easy to use. Just several clicks, the converter converts H261 files to MP4 successfully. The software supports MPEG4 and H.264 codecs for MP4 file, and supports M4V that Apple products such as iPod, iPhone, iPad use.

Besides MP4, the converter converts H261 to popular media formats and portable devices, for example, FLV, iPod, BlackBerry, MPEG, PSP, M4V, MKV, Xbox 360, OGM, ASF, and so on. The software also supports almost any video and audio file formats. It converts DVR-MS to PSP, VFW to 3G2, MVI to 3G2, OGV to FLV, Y4M to OGM, WM to 3G2, WebM to DivX, THD to ASF, and so on.

H261 to MP4 software supports batch conversion and is full compatible with 32-bit and 64-bit Windows 10/8/7/Vista/XP/2000.

H261 to MP4 Software is compatible with Windows 10, 8, 7, Vista, XP, 2008, 2003, and 2000

What is H261?
H.261 is a 1990 ITU-T video coding standard, ratified in November 1988. Originally designed for transmission over ISDN lines on which data rates are multiples of 64 kbit/s. It is one member of the H.26x family of video coding standards in the domain of the ITU-T Video Coding Experts Group (VCEG). The coding algorithm was designed to be able to operate at video bit rates between 40 kbit/s and 2 Mbit/s. The standard supports two video frame sizes: CIF (352x288 luma with 176x144 chroma) and QCIF (176x144 with 88x72 chroma) using a 4:2:0 sampling scheme. It also has a backward-compatible trick for sending still picture graphics with 704x576 luma resolution and 352x288 chroma resolution (which was added in a later revision in 1993).

The H.261 standard actually only specifies how to decode the video. Encoder designers were left free to design their own encoding algorithms, as long as their output was constrained properly to allow it to be decoded by any decoder made according to the standard. Encoders are also left free to perform any pre-processing they want to their input video, and decoders are allowed to perform any post-processing they want to their decoded video prior to display. One effective post-processing technique that became a key element of the best H.261-based systems is called deblocking filtering. This reduces the appearance of block-shaped artifacts caused by the block-based motion compensation and spatial transform parts of the design. Indeed, blocking artifacts are probably a familiar phenomenon to almost everyone who has watched digital video. Deblocking filtering has since become an integral part of the most recent standard, H.264 (although even when using H.264, additional post-processing is still allowed and can enhance visual quality if performed well).

What is MP4?
MPEG-4 Part 14, 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 audio and digital video 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. The official filename extension for MPEG-4 Part 14 files is .mp4, thus the container format is often referred to simply as MP4.
