The is XviD Codec also known as the Koepis Xvid Codec. The XviD codec, which is essentially an MPEG-4 video codec, distinguishes itself as an open-source research project. It places a strong emphasis on video compression and operates as a collaborative development endeavor.
XviD Codec
All of its code is made available under the GNU GPL license. In terms of technical specifications, the Xvid video codec adheres to the MPEG-4 Simple Profile and Advanced Simple Profile standards. Its primary function is to facilitate the compression and decompression of digital video, thereby reducing the necessary bandwidth for video data transmission across computer networks or efficient storage on CDs or DVDs. Likewise see also the Xvid Codec for Potplayer as well as the LAV Filters on here.
Thanks to its exceptional quality, Xvid has garnered widespread acclaim and enjoys extensive usage in various other GPLed applications, such as Transcode, MEncoder, MPlayer, Xine, and many others.
I often find that my older 720p/1080p Xvid encodes still maintain excellent quality when upscaled on a 4k TV. In contrast, the supposedly superior H264/MKV formats tend to look subpar. The outcome can vary depending on the TV brand, but I conducted tests with multiple 4k TVs, including LG, Hitachi, and Samsung, and all the HD videos appeared to be of lower quality compared to the Xvids. However, it’s worth noting that both formats perform admirably on 1080p TVs.
Koepis Xvid Codec
It’s crucial to understand that 4k TVs are optimized for pristine sources like H265 and AV1, and they are less forgiving when it comes to other formats. Developers face limitations due to the restrictive nature of the SAP (Simple Advanced Profile) at this point. In my perspective, version 1.2.2 was the pinnacle for Xvid. This because the subsequent 1.3x builds have been rather disappointing with their cluttered installers. This is also known as the Koepis Xvid Codec. Note also the 3ivx on here.
There used to be an Xvid 1.2.2 VAQ-based Win10 build designed for 32-bit systems. This is compatible with XP onwards, available on Xvid ru-board. However, this site no longer allows downloads or may have become an abandoned webpage with outdated information. Fortunately, you can find the 64-bit version on videohelp.
If you can’t do the other stuff I mentioned, you might want to try Koepi’s final 1.2.2 version of Xvid. It’s like a classic version that keeps things simple and works well.
The newer 1.3 versions of Xvid had some extra stuff added, like the variance AQ patch which was supposed to make things better but actually made some things worse. Even Koepi, the person who made these versions, wasn’t happy about all the extra stuff. Lastly also see the DivX H.264 Decoder and ASF Codec and MPEG-4 as well as on here.
So, if you could take out all the extra things from Xvid 1.3.7 and make the installer smaller, like 1MB or less, it would still be a really good codec.
