Deleted videos retrieved, wont play!?

[seskill]

Hello and thank you for your help. I take video with my gopro hd of me and my friends riding and accidentally deleted the files today of videos I took yesterday. Have been trying all day to recover them from my HDD and the memory card. I cant them anywhere on my HDD, but have on the memory card. The program says they are in good condition but after restoring them, no player will play them. There are five files and all are large Hd videos. Any help would be much appreciated, Thank you.

Try:
MiniTool Power Data Recovery
and
Get Data Back

[seskill]

Thank you Zoobie. Unfortunately neither of them worked. Minitool didnt find the files and Get data back seemed to have found files while it was scanning but when it got to step 2, there wasnt anything in the list. The only program that finds them and recovers them is Pc inspector. Its just that the files are unreadable. I recovered 2 of the 5 and ran them through Gspot and it only gives me the name, location and size of the file. No codec info or anything.

Thank you jagabo. But unfortunately it didnt help. I got all the files back on the memory card but when I turned the GOPRO on it didnt read them. No SOS or anything from the GOPRO itself. But when I hookup the GOPRO to my computer, they are read.

I tried the PERL script and it keeps saying,

"The system cannot find the path specified. 'perl' is not recognized as an internal or external command, operable program or batch file. Press any button to continue..."

The treasured program seems like a lot of work and money for my situation. At that point, Ill just take the loss.

That means you didn't download and install perl. Or, if you did install it, it's not in your search path.

Thank very much for the help. Sorry it took me so long to reply. I was on vacation. Well there were 4 files I was trying to retrieve. I found them, did everything you said and got them all recovered. I started repairing them and they all ended up being the same video from a different file not related to these five. So I just gave up cause I realized the right data wasnt there.

So I just went and made some more videos to make up for the ones I lost and 1 of the 5 new videos doesnt seem to work in sony vegas. I can watch it in any player and all is fine. But once I try to place it in the timeline in vegas, it doesnt work and the error message is that it failed, but it doesnt know why. Checked forums and apparently large gopro videos dont work in vegas.

Should I make a new thread or does anyone have suggestion. Thank you

I would try a remux with AviDemux. Or cutting it into smaller pieces with the same program. Leave both audio and video in "copy" mode.

Well thank you very much Jagabo. AviDemux worked perfectly. I really appreciate it. I just shortened the video with A-B cut and it works in Vegas now.

I accidentaly deleted files form my gopro. They are needed. I recovered them using jihosoft file recovery but now the mp4 wont read. Can you please help me get them readable?

[Baldrick]

Try video repair tool and see if it can find any video.

Or try the free recover_mp4_to_h264 (command line software).

I use a mac

[NeedAJUDA]

ive downloaded this software "video repair tool" but it won't install on my comp (mac) running out of options.

[WazaKrash]

maybe try to convert them/re-econde them with a converting software, for this I use FreeMake.

sometimes when I reencode, it's solve my problem.

You shouldn't install it. Just extract the content from the zip and run gs. It works on my mac osx 10.10.5.

[NeedAJUDA]

Is th esound completely lost when you recover it and fix using thesoftware?

[Baldrick]

What?

the old days, 10~15 yrs ago
working with coruppted files i would use a HEX editor and rebuild the file header

the file header is the part that identifies the file type, the lenght of the data portion, over all file size, and this ( the byte where the data starts )
to do this kind of thing you have to be familiar with the file header. how it is constructed, what info goes where, and it will be in hexadecimal,
not decimal not binary

you could google file header for mp4, and study that info
use a hex editor to (examine only) some good files
then attempt to repair one of your recovered files

i warn you, you are in for a learning curve,, it will take some time, work only on copies of the recovered file, so don't make the situation worst
