MP4 File Won't Play Back

[DDotoo]

Hi forumers ,

I use a video mixer called Vmix to live mix video feeds and record to my hard drive. I usually record in avi until I realise that I don't have the luxury of storage so I started using MP4 file. On Sunday I recorded what would probably be one of my most important videos of this year but the file won't play back. I have used all sorts of players and repair softwares and they all keep saying "format not supported". The file is clearly an MP4 video with the extension just like others I have recorded but strangely it wont open. I used the Vmix playback to play and it gave an error message to "Install Haali Media Splitter". The HMS is already there but because I am desperate I removed it and reinstalled but still no joy. I have installed another encoder still with no results. What do I do now? I noticed that the file size of 768mb would be too small for a 3hr+ recording but if I could retrieve whatever is on there I would really appreciate it.

Someone pls help a desperate amateur!

Hello DDotoo,

Not sure whether you already tested Mac application Treasured or MP4repair.org in case you're in a PC. Probably you could get some preview from them and then decide whether the clip is worth repairing. Best of luck!

Hi FireR, I have used the site you suggested and it says its not worth repairing. Thanks for your help.

Yes I have used repair tools and they give similar results as "format not supported". However the Treausres app was able to diagnose and say it is not worth repairing.

Thanks for your assistance.
