Passthrough Video Converter

DESCRIPTION Convert local videos to MP4 on Mac, iPhone and iPad. Choose a mode for your task and keep the original files. Fast Passthrough repackages supported encoded streams without re-encoding. Compatible 1080p creates a broadly compatible MP4 up to 1080p. Efficient HEVC 1080p creates an HEVC MP4 up to 1080p for compatible players. The built-in demonstration explains Add Videos -> Output -> Start -> Check Playback. Play, pause, replay or move one step at a time. Its mode selector changes the actual batch preset, so the explanation follows your selection. Videos are processed on your device. On Mac, choose an output folder; on iPhone and iPad, find results in Converted Videos in Files. Check playback before sharing. The interface supports English, Simplified Chinese, Traditional Chinese, Japanese, French, German, Russian and Spanish. User guides remain in English. The demonstration is schematic, not conversion progress. Supported input and output combinations depend on your media and device. Speed, file size, quality and preservation of every audio track or subtitle are not guaranteed.
