I read the other questions I could find. This is completely different. My question is NOT about finding the file.

The file is on my phone. It is the correct size. It shows as an mp4 with the right icon on windows. It has an mp4 suffix. It's 22+MB so it's there. It will not play in MS Media Player or with VLC player. It doesn't show up on the phone itself in the gallery, but it's there when I connect the phone to my laptop.

I was recording the video, my battery died, the phone shut off while I was recording.

There are many programs on the internet that claim to fix video files, but I'm afraid to download any of them because I do not want to get a virus.

My phone is an HTC EVO 3D. My carrier is Sprint. My laptop is a Samsung running Windows 7. I recorded it regular mode not in 3D mode.

How do I play this file? How do I fix it? What should I do? If there's a piece of software I should download to my laptop to fix it, what is a good reputable site where I won't get malware/virus?

    About the malware(virus) part, you can use VMware/VirtualBox to contain the software in an isolated environment. Then download anything in it from any site and test it on a copy of video file. No worries; I use it a lot. // Does the file show up in MX Player? Could it be possible to share this video file if there are no privacy concerns?

  • @Firelord Thanks for the quick response. I didn't know about those pieces of software to create a virtual space. Where can i download a copy and not have to worry about malware/virus/etc.? What is MX Player? I've never heard of it. I've actually got a bunch of other files like this, but I never could figure out why they were "corrupted"(for lack of a better word). I'm not sure which are of more of a "private" nature, lol. Thanks again for the quick response.

    Virtualbox(Free) or Vmware Player(You may use the Workstation as well.). MX Player is a powerful media player for Android. I suggested it in hopes that it might be able to decode and play the file somehow.

  • @Firelord My phone is such a piece of garbage, lol. I wouldn't dare install anything on it. I took it to sprint and they said it couldn't be fixed. This is my 4th one, mind you, and I got this phone the day it came out in 2011. I've had a free upgrade due me for two years but just nevered bothered cause I didn't like the new phones. They said this one couldn't be fixed and offered me a new model free phone, but I told them I couldn't just leave it with them as I needed my data. They told me I couldn't get it off cause the port was bad, but I told them I could connect it to laptop still -cont'd

I had the same promblem. A solution which worked for me was an app "MP4Fix", which you can get in google play for free. It repaired my video in a few sec and placed it in different folder (it kept corrupted video in the same place and also created new repaired one). I know this info might be too late for you but it might help some others.

To expand on Martin's answer, yes you can use MP4Fix. However it is very strict what the video is made with. I found I needed to set the recording settings in order for the mp4 video to be in a supported format and not get error 'Not Supported'

Video Encoder H264 Recorder Format MPEG_4 File Format MP4 Audio Encoder AAC

Additionally I set video resolution, framerate, and bitrate.

I was then able to recover video.

FYI: The Recording App is SVR but others are named the same. Found using: secret video recorder (free) tristan https://play.google.com/store/apps/details?id=com.tristan.enhanced_camera

  • You'd better disclose your relationship with that app.
