Below is a list of commonly used software, related to video encoding, audio encoding, and fansubbing in general. All links should work. If you find any dead links, email me and I’ll fix it.

• Aegisub (official release)

The most widely used program for fansubbing (timing, typesetting, k-timing). Loads video, audio, and subtitles. However, the official release is quite old and outdated.

• Aegisub (dev r5496)

A dev version of Aegisub which improves on 2.1.8. This one supports 10-bit. However, it is not official and is still buggy.

• AviSynth 2.58

AviSynth is a powerful tool for video post-production. It provides ways of editing and processing videos. AviSynth works as a frameserver, providing instant editing without the need for temporary files.
AviSynth itself does not provide a graphical user interface (GUI), but instead relies on a script system that allows advanced non-linear editing. While this may at first seem tedious and unintuitive, it is remarkably powerful and is a very good way to manage projects in a precise, consistent, and reproducible manner. Because text-based scripts are human readable, projects are inherently self-documenting. The scripting language is simple yet powerful, and complex filters can be created from basic operations to develop a sophisticated palette of useful and unique effects.

• AvsP 2.0.2

AvsP is a text editor designed to help create AviSynth scripts.

• Hashmyfiles

Generate CRC32, MD5, and SHA-1 hashes with this program.

• eac3to

Command line program which can convert PCM, WAV, DTS-HDMA, True-HD to WAV, FLAC and DTS.

• MeGUI

Program for video and audio encoding. Recommended for beginners to encoding. It supports MPEG-4 ASP (XviD), MPEG-4 AVC (x264), AAC, MP2, MP3, Flac, Vorbis, AC3 audio and various common containers support (MP4, MKV, AVI, M2TS).

• tsMuxeR 1.10.6

tsMuxer is a Transport Stream muxer. Remux/mux elementary streams, EVO/VOB/MPG, MKV/MKA, TS, M2TS to TS to M2TS. Supported video codecs H.264, VC-1, MPEG2. Supported audio codecs AAC, AC3 / E-AC3(DD+), DTS/ DTS-HD. Ability to set muxing fps manually and automatically, Ability to change level for H.264 streams, Ability to shift a sound tracks, Ability to extract DTS core from DTS-HD, Ability to join files. Output/Author to compliant Blu-ray Disc or AVCHD.

• x264

Command line program which encodes in h264. Has 8-bit and 10-bit flavours.

• VirtualDub

VirtualDub is a video capture/processing utility. It lacks the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters. VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images.
