What is “Version 2 (Beta)”?
512byte_developer

It is an alternative algorithm, whose advantage in joining more frames, was developed for the CPR-1602E1-TS DVR; the ability of working with other DVRs with WFS 0.4 is in the process of testing.

Why do I need to set the number of cameras?
512byte_developer

The number of cameras have to be specified for better recovery of video data via data carving algorithm Version 2.

What is the difference between the full version and the demo?
512byte_developer

The demo version of the software saves only 4 GB of video data. You can see a list of all found files in the “Log.txt” file.

 

Andrey Fedorov
Why is your software better than others?
512byte_developer

Because existing solutions from well-known companies show poor results or do not have the result at all.

Vadim Tkachuk
Why is there no division of the video stream by cameras?
512byte_developer

Because WFS Recovery carves video stream without using WFS 0.4 metadata to recover files even if the HDD was formatted, overwritten, or damaged (some sectors of the HDD were lost).

 

Andrey Fedorov
I do not know how to open the video. Which video player and codec to use?
512byte_developer

To open the video, you can use any video player and also install a popular set of codecs. For example, we use the K-Lite Codec Pack Mega.

Vadim Tkachuk
How many cameras does the software support?
512byte_developer

As many as you like. The software does not depend on the number of cameras.

Why is it worth using your software if there are many analogues?
512byte_developer

In addition to simply backing up at a specified interval. Our software changes the file extension and its header. Thus masking the file from ransomware, that scans the disk for files of a certain type (for example, documents or photos).

Vadim Tkachuk
What happens if the ransomware encrypts all the files on the disk?
512byte_developer

Then the backup will be damaged.

 

Andrey Fedorov
The “Failed to back up some files” window appeared. What does this mean? What will happen with listed files?
512byte_developer

This means that these files are open in another program, so copying is not possible. During the next backup, the software will try to copy them again.

Vadim Tkachuk
Why should I use this software if there are many online converters?
512byte_developer

Our software is aimed at mass photo processing. Recovering more than a thousand files at the same time is not a problem, which cannot be said about online services. Our software will also check recovered JPG photos using the Huffman method and save only intact files.

Andrey Fedorov
How does the software extract the photo if the file is corrupted?
512byte_developer

In most cases, the camera saves the Raw photo, Jpg preview and full-size Jpg photo separately. If any part of the Raw part or the header of the entire file is corrupted, the Jpg photo can still remain untouched. Our software extracts the Jpg and then checks it, keeping only intact photos. This distinguishes our software from the rest.

Andrey Fedorov
Why does the software save the preview?
512byte_developer

They may come in handy during forensic investigations, as they may differ from a full-size photo. Also, if your camera does not support the function of recording a full-size Jpg photo together with Raw, the preview may be the only one that can be recovered if the Raw is corrupted.

Vadim Tkachuk
Why doesn’t the software support DNG format?
512byte_developer

The three most popular formats (CR2, ARW, NEF) occupy more than 75% of the market. We decided to support the most popular Raw photo formats.

Andrey Fedorov
What are .lrv files? How to open them?
512byte_developer

Lrv files are video previews that your camera saves along with full-size video .Lrv files have less resolution and less size.
The file can be played by any video player that supports mp4 format. If the default program is not installed for this extension, you can select it through the "open with" menu.

Andrey Fedorov
Why is the start LBA value and cluster size value are so important? How does this affect the result?
512byte_developer

Due to the nature of the file system, it is very important to start reading data from a specific sector to match clustering. Our software needs to find beginning of files, which is specified by the "start" field, and also move around the source by the size of the cluster. If you have problems with these values, contact us by e-mail soft@512byte.ua and we will help you set the parameters.

Does softwareonly work with GoPro Hero7 cameras?
512byte_developer

Our software has been tested so far only on this camera model. We plan to add support for more models, and we are making appropriate tests for these.
If you encounter a problem that you cannot solve, we are ready to supplement our software for your case or create a separate software for this case.

 

Andrey Fedorov
Why does the demo version save files only less than 5 MB?
512byte_developer

We decided that when setting the limit to 5mb, a sufficient number of video previews are saved to demonstrate the operation of the software.

Hi Andrey....I'm trying to test the DVR soft but it just show me as result a list of files. No video show to verify is can recover well the data......my dvr is a ALHUA DHFS 4.1
512byte_developer

In the demo version, result is a list of the date and time a video can be recovered.

We specifically made this restriction. If we recover the video in the demo version, the user, who sets the selected image fragments to the software input, can recover the required video.

You can send me any fragment of the image, I will send you a video.

Video is available only in the full version.

Own algorithm for recovering fragmented files

Andrey Fedorov
Do you use recursion?
512byte_developer

No, we developed our own algorithm for finding fragments of a file

The software crashed and reported an error. What should I do?
512byte_developer

We recommend you to write to the support service:

  • write your email, what’s linked to the license
  • describe the error and send the screenshot to us
  • send “glog.log” file to us (that file is formed each time when the program is launched)
  • probably it will be needed to send the image file where was the error

Disk of DVR was formatted in the file system of NTFS and installed on Windows 10. Is it possible to recover the video with Infinity (IVR) Recovery?

The software will find the video files in hard disk that were not replaced with new information.

I tried to compare with RStudio, MultiExtractor and it gives similar results.
512byte_developer

Compare with the mode to search for known types of files.
