Internet Friendly Media Encoder vs Prism Video Converter

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.

Prism Video Converter converts video files between formats and can compress them. It runs on Windows and macOS, supports batch conversion and can handle input video up to 4K resolution. Its output list includes video formats such as AVI, MP4, MOV, MKV, WMV and WEBM; audio formats including MP3 and WAV; and image outputs such as GIF and JPG or PNG sequences. Before conversion, users can trim, split, rotate, flip, crop or resize video, add text or image watermarks, and adjust color effects. The product page also describes direct sharing or uploading to YouTube, Vimeo, Dropbox, Google Drive, OneDrive, Flickr and Twitter. Prism can burn converted videos using NCH Express Burn software. The maker’s page describes conversion as an offline process. The free version is for non-commercial use and converts to AVI, ASF and WMV without upgrading. It includes Prism Plus features for a 14-day trial after installation; those advanced features are disabled afterward unless a Plus license is purchased. Paid annual plans are $39.95+VAT/year for Home and $59.95+VAT/year for Plus.
