Andy - a15cro Posted June 20, 2016 Share Posted June 20, 2016 I've a piece of film off my go pro that I can't view as I think it didn't finalise or whatever it does because I dropped it before turning record off. Can anyone help, I promised a company the footage as we hired in a crane for a lift and they wanted to use it on their web site. Quote Link to comment Share on other sites More sharing options...
AdamR Posted June 21, 2016 Share Posted June 21, 2016 Yes - here goes... most is a copy and paste from a forum thread, but it made sense to me Normally the utility will only repair 50% of the file for free (you have to pay an outrageous 29 EUR for a mere 5 repairs, or 99 EUR for unlimited repairs--probably more than you want to spend just to repair a stinking video file). Fortunately, there is a way to trick the demo version into repairing the full video. It calculates how much it will repair by file size. So....double the file size of the source video, and it will repair the whole thing!To do this:a. Make a copy of your corrupted video file and put it in the same directory as the original. Rename the two files something simple like "video1.mp4" and "video2.mp4."b. Open the Windows command line (run>cmd) and navigate to the folder with the video files using the cd command.c. Type "copy/b video1.mp4+video2.mp4" (without the quotes) and hit enter. It will now merge video2 into video1, so video1 will have doubled in file size. Download this program: http://www.tartybikes.co.uk/media/videorepair.zip Disconnect from the internet (IMPORTANT step!) Open the zip file, run gs.exe and choose English unless you are fluent in Chinese. 3. Select the "repair" action. Click the "Choose movie" button and select your merged video file (video1.mp4 in my example). Then click the "Choose reference movie" button and select any other properly functioning raw video file from the same camera to serve as a reference file.4. Click the "Scan" button and wait for the utility to repair the file. You should then be able to find the full repaired video in a newly created sub-directory of the source folder called "repaired."5. Your video file should now be repaired and will play smoothly up to the moment when your camera quit recording (GoPros will typically lose the last 30 seconds before a crash). Has worked a few times for me, good luck! 2 Quote Link to comment Share on other sites More sharing options...
Andy - a15cro Posted June 21, 2016 Author Share Posted June 21, 2016 Thanks, I will give it a go although I need to find the mac method on Google. At least now I know I have a chance to fix it. Quote Link to comment Share on other sites More sharing options...
AdamR Posted June 21, 2016 Share Posted June 21, 2016 Stupid macs I'll dig out those instructions later. The program I uploaded may not work though, and the latest version can tell that you are 'cheating', so it could be worth finding someone with a PC...

Andy - a15cro Posted June 22, 2016 Author Share Posted June 22, 2016 Ive a Windows laptop I just need to put my hands on it for a last resort! Quote Link to comment Share on other sites More sharing options...
Andy - a15cro Posted June 30, 2016 Author Share Posted June 30, 2016 I tried to fix the vid on the mac and I can do 50% no problem, what I can't do is double the size of the original file! So I fired up my Windows laptop and can even do it on there because I don't understand command line prompts etc. Can anyone double the file size for me so I can repair it please?

CraigHew Posted July 1, 2016 Share Posted July 1, 2016 What Adam is suggesting is making a copy of the video, then adding the two together, which effectively doubles it's size. Using Windows, use Windows Movie maker, its very simple to add another video to the end then save the larger file. Can't speak for Macs as I avoid anything apple like the devil Quote Link to comment Share on other sites More sharing options...
AdamR Posted July 1, 2016 Share Posted July 1, 2016 The issue is that the file is corrupt, so won't load up... Andy - PM me your number and I'll give you a call to talk through the steps. Quote Link to comment Share on other sites More sharing options...
