MP4tools overview

MP4tools is an offshoot of the current version of the popular conversion tools called MKVtools. It is an OS X application used for the creation and editing of MP4 videos. It was primarily designed for processing videos files for use in hardware capable of playing MP4 or M4V videos, such as the iPhone, iPad, Apple TV and PS3. As the name might imply, MP4tools is a graphical interface for a variety of "tools" useful for processing video files.

Features

Convert from a variety of video file formats like MKV, MP4, OGM, and AVI into MP4 videos.
Can convert most videos without having to re-encode the video track and/or the audio track, so processing takes minutes instead of hours, and no quality is lost.
Simplified, intuitive user interface that takes the guess work out of processing MP4 videos.
Ability to convert various surround sound audio to 5.1 AC3 or 5.1 AAC.
Intuitively select desired video, audio and/or subtitle tracks to process, with the ability to verify the selections using video preview.
Use presets for one-step encoding for playback on common hardware such as the iPhone and Apple TV.
Burn (i.e., hard code) subtitle tracks into the video, or mux (soft subtitles) from internal tracks or from external subtitle files commonly found on the internet.
Control the font, size, and positioning of the embedded subtitles.
Split MP4 videos into segments of a specified file size or by start/end time.
Adjust the pixel aspect ratio of MP4 videos.
Join MP4 videos.
Extract the selected tracks from MP4 videos as individual video and/or audio files.
Add jobs to a queue either individually or in batches via drag-and-drop so you can process multiple files overnight (registered copies only).
Apply one setting to a group of files for easy batch creations (registered copies only).

Good app. Only use it sparingly but decided to pay for a registration code for an unlocked version. Unfortunately no code and seemingly no longer supported. Happy to take my money though. Buyer beware I guess. I should have checked these comments first.

It's always sad to see such a useful app abandoned. I don't know if it's the case, but Covid deeply affected small companies, I see many shareware last updated in 2019, be the dev dead, gone bankrupt or else... :(

Indispensable! Great app! When will the developer provide an update? I hope it's soon... I'd like to see support for chapters, support for 7.1 sound, support for Dolby Digital Plus, HEVC X265 support, an updated device list, to name but a few.

Failed several times in a row to do the job. What else can I say than it is a waste of time and you'd be better off looking elsewhere? Nice concept, but this one needs some work before an official release!
