Format Factory vs Internet Friendly Media Encoder

Format Factory is a free Windows program for converting and processing video, audio, pictures, discs, PDFs, and archives. Its video tools convert, clip, join, split, mux, crop, and remove logos; supported outputs include MP4, MKV, FLV, M3U8, 3GP, AVI, WMV, H.264, H.265/HEVC, AV1, and VVC/H.266. It supports batch conversion, hardware acceleration, output up to 4K, audio extraction, and repair of damaged video and audio. Audio functions include conversion, clipping, joining, splitting, and mixing. Picture tools handle WebP and HEIC conversion, zoom, rotation, flipping, and tags. It can rip Blu-ray, DVD, and Music CD content, join PDFs, convert them to text and office formats, and extract JPGs. It also decompresses Zip, RAR, and 7z archives and downloads video from sites including YouTube and Youku. The listed version is V5.22.0.0, with a download size of 162M, and it supports 62 languages. The official PC software and all functions are free; paid versions are described as pirated.

Internet Friendly Media Encoder (IFME) is a free Windows and Linux tool for encoding, remuxing, and repackaging video and audio. Founded in 2011, it supports batch conversion, hardware acceleration, and audio extraction. Containers listed include AVI, MP4, MKV, TS, M2TS, MPG, MPEG, WebM, and WMV; codec options include MPEG-1/2, WMV-2, H.263, H.264, H.265, H.266, AV1, VP8, and VP9. IFME handles subtitles and font attachments, combines multiple streams, removes unwanted streams, and extracts subtitles from another video. Bundled video encoders include x264, x265, SVT-AV1, uvg266, vvenc, libvpx, Xvid, MPEG-1/2, and WMV 8. Audio options include AAC, Opus, Ogg Vorbis, FLAC, AC-3, MP2, MP3, WMA, and WAV. JSON manifests let users update, replace, or add encoders without recompiling. AviSynth scripts support advanced processing. Hardware encoding for H.264, H.265, and AV1 uses FFmpeg, NVEncC, or QSVEncC. An AVX-capable CPU is required, with AVX2 strongly recommended. Linux needs Mono and user-supplied encoder binaries because bundled plugins are Windows binaries. The project lists GPL-2.0 licensing, recommends SourceForge downloads, and warns codecs may involve patent royalties.
