Video Recovery. Blank Visual and Static Sound

#1 Post by fadetoinferno »

My Situation: Accidentally formatted card with important video. I've tried other recovery software, some have recovered files but the videos are unplayable. I have now tried Photorec and has successfully recovered the video files and it is playable through quicktime, however, the visual is Black and the audio only has static with some bits of the original audio. I was wondering if I may have not used the software correctly? or perhaps the files are corrupt? is there another software I could use? Please let me know your thoughts on how to fix this or what you recommend I do?

hello - i am having exactly the same problem. accidently, all "images" (this includes videos) had been deleted from my sd card in camera. I had also tried recovering the files with the software iMacShare Data Recovery, but with both programs, the .mov files only contained a black or green image and static or no audio.

the jpgs and cr2 image files all recovered fine.

do you have any idea how to get to those files or how to repair them? or why only the video files are corrupt?

just an update on this. Turns out the MOV video files are broken. So you need an video repair tool. I have yet to find one that's free but this one does in fact work.

you can try the demo and take a look at the footage only thing is it only restores half of the clip.

Looks like that there are different problems.
If you'd exactly reformat your card like before, you'll overwrite the file system.
The result is a newly created empty file system and this is not reversible.
You'll need datarecovery software like PhotoRec which reads data underlying in your sectors and ignoring the file system.
If you have deleted files you can use TestDisk to check it using Undelete.
You'll find it in TestDisk at Adavnced / Undelete.
You can have a try to copy deleted files.
Deleted files appear red colored.
It would be possible that Undelete achieves better results because often folder and filenames are kept.
In both cases only files are recoverable as long as they're not overwritten.

Unlike JPG pictures that are easy to recover, video files can be huge in size and in so many different formats that through standard data recovery algorithms only works in the "happy path". Usually you will need to use a specialized video repair tool.

You can preview your corrupt video files with:

Some of the recovery softwares doesn't support video recovery and its necessary to check weather the software supports the video file format which you had lost. You might not used the software correctly or it can be software fault you cannot say anynthing very surely, its better to use other recovery software and do it one more time. May this time you will recover your lost videos completely.

Lost .MOV files from a Canon EOS 60D (SD card)

Hello!
I live in Brazil, and I need to restore about 35 GB of .MOV files that have been lost on a 64GB SD card, accidentally formatted in a Canon EOS 60D.
They are HD videos from a wedding party!
I've been using PhotoRec for years, but every time I deal with videos, especially with newer versions of digital cameras, I find a new challenge.
This time PhotoRec recovered around 270 .MOV files, not directly playable through any known player, like VLC, KMP, MPClassic, or even QuickTime.
After a repair operation through Grau GbR's HD Video Repair Utility, I am able to play the video. Unfortunately, I am unable to buy this expensive software, and the demo stores half the size of each repaired file.
So, it would be very nice if PhotoRec could do this job without further rework.
I am using PhotoRec version 6.14, on a Windows-based PC.
Thank you for any guidance!

Best regards,
Max.

PS. I wonder if it would be possible to simply unformat the SD card... :mrgreen:
