**MashedData**

This file doesn't seem to be a movie file, maybe it just contains one or several very short movies, or maybe no movie at all.

This usually happens after data loss, or after a data recovery software has repaired a hard disk or a storage device.

**AlienData**

This file can contain one or several movies. Part of the file corresponds to something else. Maybe only part of the original footage is still here.

**CanBeMovie**

This file seems to contain a movie.

**CanBeMovieLow**

This file has a low and homogeneous data density. It can contain a movie, but certainly not one encoded with efficient audio and video codecs.

**DataIntegrity**

A quick way to check that a corrupt file still contains the media data, which is a necessary condition to repair it, is to evaluate its compression rate with zip utility. Audio and video data will give a low compression rate whereas other type of data will be around 50% or higher.

We perform this check on several slices inside the file. The table below indicates the compression rate for each slice. If a slice has a compression rate above 50%, then Data Integrity of the movie file has been lost: This slice cannot contain movie data.

**ContainerFound**

Multiple moov atoms found, but last one is corrupt

When you edit a movie in-place (ie without writing again all the file), some edition softwares just add a new moov container at the end of the file, without bothering to remove older ones. If the file has become corrupt, those old containers can still work. The trick consists in finding the moov structures and redirect towards an older one. You'll need an Hex editor and good knowledge of QuickTime file format to do that.

**VerySmallFile**

Movie files usually have a size ranging between 10MB to 50GB. This file, however, is less than 1MB in size. Such very small files are very unlikely to contain any interesting movie.

Some software failures can truncate a movie file to a very small size, making the repair impossible. In the event of a storage failure (hard disk drive, memory card, ...) a file size can also dramatically change, even after using a recovery software. Chances of repair are thin.

A very small movie file is possible when a movie is saved by referencing the media from another file. The bulk of media data is not included in such movie file. If ever the referenced file is deleted or lost, such movie file becomes useless and repair is impossible.

**OpensInQT**

Surprisingly, this file can be open with QuickTime Player or any other QuickTime-based tool.
Being able to open the file indicates that the file contents are still organized in a consistent structure.

Entering tracks description in the search field above can bring in additional information.

**TroubleshootThem**

Note that even if the file is good, Treasured will analyze it as if it were bad, thus not using the fact that it can be open. In other words, a good file that falls out of Treasured current capabilities (for example, Animation video codec) will give a negative diagnostic.


Troubleshooting Tips

Issue Action
Stall or crash during playback
(can happen at a specific "rough spot" time, or randomly)
Diagnostic, Repair
Frames that display with colorful artifacts. Diagnostic, Repair
Movie length is much smaller (even zero second) than its size indicates. Diagnostic, Repair
No video, or no audio at all (black window, silent movie). Verify codecs*
Audio playback issue, lack of synchronization Out of scope*

* Verify that the audio and video codecs used in the movie are present on your computer. Otherwise you get a black window or silent movie.
* Audio synchronization issues are not solved by movie repair.

**FileAttributes**

This movie file has some "Finder attributes" that can help in the repair.

A legacy from Classic Mac OS, the resource fork, creator and type codes can still be found in some movie files, and play an important role. A missing resource fork, or a wrong type code can confuse QuickTime and prevent the movie from opening. 

**MissingCodec**

Althrough the media has been found, it cannot be decompressed, because the corresponding codec is not installed in your system. No Preview is available.

DVCPro HD, HDV, Intermediate, XDCAM and ProRes422 codecs and usually distributed with Apple pro video software (Final Cut Pro). They don't come preinstalled with the operating system.
Note that if you install a missing codec, changes will only take effect after quitting and launching again Treasured.
If the codec is still reported as missing even after checking that it's installed, it's maybe because you are installing a PowerPC codec in an Intel Mac, or the other way around.
You can check by doing Get Info in Finder, and looking at Kind field.
Kind: Component (Universal), will work on both PowerPC and Intel
Kind: Component (PowerPC), will work only on PowerPC Macs.
Kind: Component (Intel), will work only on Intel Macs.

Workaround to make PowerPC components work on Intel Macs:
Launch Treasured in "Rosetta". To do that, select Treasured.app in Finder and do Get Info. There should be an option called Rosetta. Check it, and Treasured will be executed in PowerPC emulation mode, thus accepting PowerPC codecs.

**StartsLikeQT**

The beginning of the file corresponds to QuickTime format. It means that the file was originally saved in one of those formats: mov, mp4, m4v, 3gp.

**StartsLikeAVI**

The beginning of the file corresponds to AVI format. If the file cannot open, then probably the AVI structure is not complete or consistent.

**StartsLikeWMV**

The beginning of the file corresponds to WMV or ASF format. If the file cannot open, then probably the structure is not complete or consistent.

**StartsLikeFLV**

The beginning of the file corresponds to FLV (Flash Video) commonly used on web pages and on YouTube. If the file cannot open, then probably the structure is not complete or consistent.

**StartsLikeMatroska**

The beginning of the file corresponds to Matroska format, commonly used to store High-Definition contents. If the file cannot open, then probably the structure is not complete or consistent.

**LostFork**

The beginning of the file corresponds to a QuickTime format made of a data fork and a resource fork.

The resource fork can be accidently lost during file or movie operations. Without resource fork, such a movie cannot open.

**OneQTStructure**

A QuickTime moov structure has been found. It can give additional information useful for the repair.

If the file doesn't open despite having a moov structure, it's maybe because the structure is incomplete or corrupted.

Another possible reason is that the file contains alien data, or that it contains a good movie embedded inside the file.

Such cases open the possibility of a repair by "Container Structure Correction".

**SeveralQTStructures**

Several QuickTime moov structures have been found. They can give additional information useful for the repair.

If the file doesn't open despite having moov structures, it's maybe because the active one is incomplete or corrupted. Older moov structures may be valid.

Another possible reason is that the file contains alien data, or that it contains good movies embedded inside the file.

Such cases open the possibility of a repair by "Container Structure Correction".

**NoQTStructure**

The expected QuickTime moov structure is not present. This happens when the recording or saving process has been interrupted before the end.

**NoMediaFound**

The file doesn't seem to contain any of the types of media that Treasured is searching for: DV, DVCPro50, DVCPro HD, HDV, MPEG4, H264, Intermediate, JPEG, ProRes422, XDCAM, MPEG.

It can either contain a different type of media, contain only traces of media, or contain no media at all. This information can be provided by the Density and Container tests.

Go to Preferences, select those tests and run the diagnostic again if you want this additional information.

**VideoDefinition**

Treasured has found a video track description.

Althrough the movie container is damaged, and the file is unplayable, this track information can be very helpful to preview the movie in Treasured, and later to repair it.
Entering this track description in the search field above can bring in additional information.

**Counterfeit**

The data comes from a counterfeit SDHC card.

Since 2009, many SDHC cards sold from untrusted sources are indeed counterfeit. Instead of having the advertised capacity (16GB, 32GB, ...) they only have a fraction of it.
All the data written beyond that point is just ignored. The card continues to accepts picture, movies, but the files only contain garbage data.
Unfortunately, it's impossible to recover data from such files.

Please contact repair@aeroquartet.com for advice.

**PerianMissing**

Althrough MPEG4 Video media has been found, it may not be decompressed and displayed correctly, because Perian codec is not installed in your system.

Perian is a free codec. We encourage you to install it now, to improve the diagnostic and repair results.
Note that if you install Perian codec, changes will only take effect after quitting and launching again Treasured.
