Some information needs to be updated, we will do it soon.

Please accept our apologies for not having up-to-date information about this topic.

Nevertheless, we keep offering repair services for this type of damaged footage — with same level of quality as ever — and we will continue to do so in the future.

Feel free to tell us about the content you would like to see in the revised page, using the feedback widget at the end of the page.

This is a list of tools that can be useful to repair movies.
None of them will do miracles: Repair is a very specialized task. Having a hammer doesn't make you a good carpenter.

But carpenters need good hammers!

Synalyze It!

An hex editor with grammar-based parsing built-in.

Synalyze It! is a very powerful tool to reverse-engineer or examine the content of a file. For Windows and Linux users, this utility is called Hexinator.

It not just displays the content of a file in hexadecimal form, but also analyzes it through the lens of a “grammar”, that specifies the syntax of the content of the file.

Starting with a plain hex view, as you identify structures and data inside them and code their syntax into the grammar, Synalyze It! “colorizes” the hex code and makes it readable.

Below, the first page of a R3D file reveals the video properties and its metadata when the grammar is applied.

You can write our own grammars, to visualize specific data structures and perform specialized tasks on them.

With support for scripting and integration with external programs, Synalyze It! can do almost anything, like parsing entire movies or even repairing videos.

At Aero Quartet, our technicians use Synalyze It! on damaged videos to visualize metadata, to parse them, and to prototype some repair algorithms.

However, we don't use it in the Repair Kits, which must be fast, robust and standalone apps.

Hex Fiend

http://www.ridiculousfish.com/hexfiend/

A free, open source hexadecimal editor for Mac OS X.
In-house, we use a modified version optimized for video and audio structures parsing.

This program is very good at modifying, splitting, rearranging and constructing binary files.
A Swiss-army knife for binary, if you will.

Atom Inspector

Displays the QuickTime atoms found inside a MOV or a MP4 file as a tree structure and allows to perform small changes.

Freely available for Mac OS X, but this is an old program by Apple, nowadays hard to find.
Last macOS version where it works is 10.14 Mojave.

Dumpster

Displays the structure of a QuickTime movie as an atoms tree, and allows to perform small changes.

Freely available for Mac OS X, but this is an ancient program by Apple, nowadays hard to find, and that only runs on 32 bit mode.
Last macOS version where it works is 10.14 Mojave.

xxd

A command line hex editor for Mac OS X.
Can display files contents and also apply patches to file.

xxd -s 0x30 -l 0x100 original.mov
