What exactly means REPAIR? Repair means that only video and audio portions can be repaired that are not lost: On some of your corrupt files, it MAY NOT repair anything at all, on some files it MAY repair some video portions, and on some other files it MAY repair both video and audio portions (It fully depends on the grade of corruption).
Features:

  • Repairs video files that are truncated, broken, corrupt or damaged
  • Repairs video files that do not play in QuickTime or Windows Media player
  • Repairs movies that were not finalized by the camera
  • The repair does not depend on a valid/correct container format – the raw video and audio stream data is fully automatically reconstructed
  • Supports non-broken reference movies for finding missing movie meta-data and parameters

Currently, our software can automatically repair damaged .mov, .mp4, m4v, or .3gp movie files (generally, all movie files based on QuickTime container format) that use one of the following codec formats:

  • avc1 (H264/AVC, used by most digital cameras, HD video cameras, iPhone, etc.)
  • hevc (H265, used by modern digital cameras, video cameras etc.)
  • mp4v (H264/ISO, used by a few cameras)
  • MPG2 / xdvc / xd5d / xd5e (MPEG-2 / XDCAM, used by Sony cameras)
  • jpg (Motion JPEG,used by Panasonic cameras)
  • icod (Apple Intermediate Codec, used by Final Cut)
  • dvc / dvpp / dvhp (DVCPRO / DVCPRO HD, used by Panasonic cameras)
  • apch / apcn / apcs / apco / ap4h (ProRes 4444/422/LT/HQ/Proxy, used by Final Cut)

Movies of the following cameras have been tested for correctness with our software (however we cannot test all camera models, and it generally works on most digital cameras):

CamerasNotes
Blackmagic URSA Mini 4.6KFor PCM audio, choose ‘Enable PCM detection’
Canon 60D, 5D, 7D, T1i, EOS 550D, Powershot SX20, S95For PCM audio, choose ‘Enable PCM detection’
Canon 574HDFor PCM audio, choose ‘Enable PCM detection’
Contour HD Helmet
DJI Mavic Pro, DJI Phantom Pro, DJI Vision Plus 2If video is stutters, choose ‘AVC1 single mode’ and ‘No CTTS repair’ under options.
Drift HD720Experimental: Choose custom repair parameters ‘-single’ under options.
Flip Ultra HD
HTC EVO 4G
GoPro, POV.HD, Contour+2, ActionPro X7If repaired video is hanging, try activating ‘No CTTS repair’ under options. If audio is missing, choose ‘Enable AAC detection’. If you recovered a GoPro/ActionPro video from an SD card media, your repaired video may freeze every few seconds. The reason is this camera stores additional files and your recovery software cannot filter out the additional files, and puts the data into the video files. Solution: use our data recovery tool (MaxDataGenius) to first extract the correct MOV files from your media.
iPhone, Nokia N82, Nexus One, all Android phonesIf repaired video quality is bad, choose ‘No CTTS repair’ under options. If audio is missing, choose ‘Enable AAC detection’ under options.
Liquid Image HD320, Toshiba Camileo S30, B10, P100,

Olympus Tough TG-810Choose custom repair parameters ‘AVC1 single mode’ and ‘No CTTS repair’ under options.
Oregon ATC9K
Panasonic HVX200, HXDC1, DC-GH5If you have a corrupted .MDT file, use it for repair and rename it to .MP4 before running the repair. Choose ‘No CTTS repair’ under options if repaired video is hanging. If audio is bad, choose ‘Enable PCM detection’ under options. If video does not play at all, try option ‘Overwrite existing codec information by reference file’ . If importing of repaired videos does not work, reparied video must be converted after repair – reenconding/converting (using ffmpeg) for import is included in the program under options: If you choose ‘MP4 (same quality)’ it will use ffmpeg to convert the videos for import. Note: do NOT use Panasonic’s SD card file recovery (AVCCAM), the recovered MOV files are unrepairable. Solution: use our data recovery tool (MaxDataGenius) to first extract the correct MOV files from your media.

Step 1: Add your camera model with a simple click here (we will update our software for your camera model as soon as possible)

Step 2: Verify that your camera model is supported by ‘reparing’ a non-broken sample file

If your camera model isn’t listed above, or the repair tool doesn’t seem to work with your movie, please first try the ‘repair’ using a non-broken (playable) sample movie of your camera to find out if the program fully supports your camera:

  1. Download the video repair tool DEMO version (.zip), and extract the downloaded archive by double-clicking it in the OS X Finder (Mac) or Windows Explorer (PC).
  2. Run the video repair tool by double-clicking the application ‘gs.app’ (Mac) or ‘gs.exe’ (PC).
  3. Click on ‘Choose movie…’ and choose a non-broken sample (playable) movie of your camera. Using a non-broken sample movie you can verify if the program fully supports your type of camera.
  4. Click on ‘Scan’ and wait until the scan finished (spinning cursor disappears).
  5. Click on ‘Preview’ to check if the movie could be ‘repaired’. If your sample file doesn’t repair, please send us a link to your non-broken sample movie (e.g. using some freely available online file sharing service such as www.wetransfer.com or ask us for our FTP), so we can add support for your camera to the repair tool.

This approach ensures that there are not two issues at the same time (program does not support your model, and damaged files does not contain any data). If it properly supports your camera model, but doesn’t work on the damaged file, the damaged file is too broken for a repair.

After you sent us your sample movie, we’ll try adding support for your camera (this may take some weeks). All customer files are kept confidential.

Step 3: Your sample file repairs, but your broken movie doesn’t repair
If your sample movie correctly repairs (step 1), but your corrupt file doesn’t repair, we may check your corrupt file. Send us your corrupt movie (and one working sample movie of your camera) using an online file sharing service such as www.wetransfer.com (up to 2 GB files), www.wesendit.com (up to 5 GB files) or www.filemail.com (up to 30 GB files). After you sent us your truncated broken movie, we’ll examine it (this will take a few weeks). All customer files are kept confidential. Please only send small sample files (max. 100 MB), as we do not have a fast Internet connection here.

Contact: Please always follow the two steps above to contact us via e-mail – Following those two steps is the only proper way we can help. Click here to contact us! NOTE: Due to the many requests we get, this will take time, and due to the many requests, we may not be able to answer to your specific request.

CONVAL can be used in conjunction with a license key only. Without a valid license CONVAL 9 can be used in a DEMO mode within 14 days after the first program run.

CONVAL supports two designs of license keys: SentinelLDK hardware and software keys and Aladdin Hardlock modules. This document applies to license keys of the type Hardlock only.

We differentiate between two different license key types for both designs:

·Local, single-user license key, which must be installed on the PC on which CONVAL is running.

·Network license key, which can be installed on any server or workstation computer in the network and which provides the maximum number of simultaneous CONVAL users.

Local, single-user licenseS

If you are using CONVAL with a local license key, you will have to install license module drivers on your PC. The CONVAL setup asks for the license and license key design and installs the license module drivers automatically. For a manual installation you find the license key drivers in the download section of our homepage www.conval.de.

Communication with the CONVAL server (that is the computer, which contains the CONVAL network license key) is made over TCP/IP. The CONVAL server can be either a Windows workstation or a Windows server. Please ask our support team if you want to use other operating systems.

The installation of the CONVAL network license depends on the applied license type.

Hardlock hardware keys

If you use the green Network Hardlock modules of a previous CONVAL version, you must install the Hardlock Server on the CONVAL license server.

You can find the installation programs as well as other useful information in the download section of our homepage www.conval.de.

Please make sure, that after installation the UDP port 3047 is not blocked by a firewall and the Hardlock Server service is running.

If your CONVAL license has an expiration date you can update it with the license information update file *.VTC which corresponds to the license serial number. The procedure is identical regardless of whether you use a local or a network license. No special rights are necessary on a license server are necessary.

To apply the license update open the CONVAL license information dialog, select the [Information] tab, click on the [Update license] button, and follow the instructions.


If there are issues with the local Hardlock license key you should make sure to have the correct “Find options” in the CONVAL “License information” section and to have installed the recent versions of the CONVAL program and the license key driver. Both can be found on the download section of our homepage www.conval.de.

To achieve a clean installation, you should begin from scratch:

·You should uninstall all Sentinel and Hardlock Device Driver first.

·You should remove the Windows environment variable HL_SEARCH if it is set.

After having installed the driver correctly, the red light of the USB license module should be always on, not flash. Otherwise the license module might be broken.

To optimize the access to the Hardlock module, you may select the following options:

·Please select “Hardlock-Dongle” in the “License management” section

·Please check the box “Search for local dongle” and the correct “Editions” settings

Hardlock Diagnostics

If you still have problems, please install and run the Hardlock DiagnostiX program.


Please select Hardlock on the left hand, enter the module address
28373, chooselocal access mode, and press the [Check Key] button.

Then create the report file using menu [Edit] and [Create report] and send both report files to our technical support team.

If there are issues with the network license module you should make sure to have the recent versions of all soft­ware parts on your computers. Therefore please download the CONVAL License Module Server and the License Monitor from the download section of our homepage www.conval.de.

Step By Step Installation

To achieve a clean installation, you should begin from scratch:

·On the computer, where the CONVAL network license module is mounted, you should uninstall all Hardlock related programs: CONVAL HL-Server, Hardlock Device Driver, Hardlock Server, Aladdin Monitor and Aladdin DiagnostiX.

·Additionally the CONVAL license information files should be deleted. Please search for all corresponding *.ALF files on your computer and delete them.

·You should remove the environment variables HL_SEARCH and HLS_IPADDR, if they are set.

·Before you run the HL-Server setup you should un-mount the license module and deactivate any virus protec­tion software. Later you will be asked to mount the license module while installing the CONVAL Hardlock Server.

·If you use a firewall (activated by default under Windows XP SP2 and later) the UDP port 3047 (decimal) has to be opened.

·Then you should install the recent versions of the CONVAL Hardlock Server and Aladdin Monitor.
The installation of the Hardlock Server needs local access to the computer. Therefore you must not run the setup in a
terminal server session.
You should establish an internet connection, or you have to enter the disk with your CONVAL License Infor­mation, which corresponds to the serial number of the mounted Hardlock.

After having installed the CONVAL Hardlock Server the service HL-Server should be running.

The manufacturer of the license module recommends deactivating the Data Execution Prevention (DEP) for the program HLS32SVC.EXE, if there are incompatibilities running under the 64bit operating systems.

How to Change The Data Execution Prevention Settings

·Open System by clicking the Start button, right-clicking Computer, and then clicking Properties.

·Click Advanced system settings. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

·Under Performance, click Settings.

·Click the Data Execution Prevention tab, and then click Turn on DEP for all programs and services except those I select.

·To turn off DEP for an individual program, select the check box next to the program that you want to turn off DEP for, and then click OK.

·If the program is not in the list, click Add. Browse to the folder C:WindowsSYSWOW64, find the executable file for the program HLS32SVC.EXE, and then click Open.

·Click OK, click OK in the System Properties dialog box if it appears, and then click OK again. You might need to restart your computer for the changes to take effect.

Note: To turn on DEP for a program, clear the check box next to the program that you want to turn on DEP for, and then click OK.

Aladdin Monitor

After having installed everything successfully please start the Aladdin Monitor.

Please select the local computer in the tree-view on the left hand, enter the module address 28374 on the right hand, and press the [Add] button: The dongle can be found in the table above.

If you cannot find your local computer in the tree-view make sure that the UDP port 3047 (decimal) is not masked by your firewall and the Hardlock server service is started.

Now please double-click the local computer in the tree view and select the dongle-icon with the number 28374.


License Information

On the right hand you should see two tables, the license information and the login table. If you see only one table, the Hardlock Server has no access to the ALF license file. In this case you should remove the environment variable HL_LICENSEDIR, if it is set, and restart the Hardlock Server setup.

If your CONVAL license has an expiration date (shown in the fifth column Exp. Date) you have to update your Hard­lock with the license information update file *.VTC which corresponds to the Hardlocks serial number.

Therefore click on the module with the right mouse button, select Update from the popup menu, open the VTC-file, and press the Apply update button.

After having done that you should restart your computer or stop and restart the Hardlock server service at least.

Alternatively you can perform the license update via internet with the CONVAL program as described in chapter Update License above.

You can use the Aladdin Monitor if you want to check who is currently using CONVAL. In the login table you find the IP addresses of the CONVAL users which are using the server license. Logging is not available.

CONVAL Client

If you start CONVAL, the network license module should be found automatically. If it is not, you can control the search in the up-popping dialog.

To optimize the access to the server Hardlock module, you may select the following options:

·Please un-check the box Search for local dongle

·Please check the boxes Search for network dongle, TCP/IP, and IP addresses / computer name.

·Enter the IP address or name of the CONVAL License Server.
If you want to use CONVAL on the server itself, you have to enter „LocalHost“ or „127.0.0.0

If the response time of your network is too long, you can change the timing options and enter a higher wait time (default: 1000 ms) and a higher number of retries (default: 5).

Devices


After having done that, press
OK and restart CONVAL. The module should be found now.


Hardlock Diagnostics

If you still have problems, please install and run the Hardlock DiagnostiX on both computers, the CONVAL license server and the CONVAL client.

Please select Hardlock on the left hand, enter the module address 28374, chooselocal access mode, and press the Check Key button. Then switch to network access mode and press Check Key again.

Then create the report file using menu Edit and Create report and send both report files to our technical support team.
