Remuxer

Most of the time your videos are already encoded correctly and just the video container is wrong, so they won't play directly on your device. Remuxer muxes your videos losslessly into an MP4 or MKV container, so you can play them directly on your device, and converts them with your device's hardware encoder when they need it. - Fast muxing of H.264, HEVC and AV1 videos to MP4 or MKV, without re-encoding - Convert videos to H.264 or HEVC with the hardware encoder, at the quality you choose - Exclude unneeded tracks to reduce file size, and reorder the ones you keep - Add audio and subtitle tracks from other files (SRT, ASS, VTT, PGS, AAC, AC3, DTS, FLAC and more) - Fix out-of-sync audio and subtitles with a sync correction for each track - Export audio or subtitle tracks on their own (M4A, AC3, SRT, SUP and more) - Downmix audio to AAC or AC3 with 2.0 or 5.1 channels - Import metadata and artwork online from TheTVDB, TheMovieDB and the iTunes Store
