Question / Help Long video not readable

[mdandrewm]

So, I recorded a video today and it was really long. So long that the file is 5.28 Gb. I recorded it onto an NTFS drive, so it should be fine, but I can't open it with anything. Any suggestions on how to recover this video?

Things I've tried thus far:
VLC
Windows Media Player
Windows Movie Maker
Wondershare Video Converter Platinum

If you need any more information, I will gladly respond with it, just ask. I really need this footage.

I have found that OBS recorded videos are fairly random in regards to being broken or not. Many many many times it will produce vidoes that are completely broken. When that happens, and I happen to stream as well, I go to http://www.twitchtools.com/video-download.php and download my videos one by one. If you didn't stream, then I currently do not know of an app that can fix mp4/flv files - Only avi.

I have actually never had an issue with OBS creating broken files. This seems like it may be something with my computer having issue with a file that size, but as OBS is the closest related software, I figured I'd try asking through these forums.

OBS recorded videos aren't 'randomly broken'. The files only get broken if OBS crashes (for whatever reason) while recording an MP4 file. Otherwise the files are fine.

Anyway, there is a known issue with very large files. This isn't due so much to the files being broken, but typically due to the video players not handling giant MP4 files properly.

There are a few ways to deal with this.
1.) Get the 64bit version of VLC, though that doesn't always seem to work,
2.) Record with FLV, or
3.) Remux your large MP4 to FLV or another container format.

Actually they are quite "randomly broken" and "unplayable" and missing all kind of stuff.
It's been an issue ever since I started using OBS like a year or two ago. Don't tell me you are unaware of this?? That would be odd. And no, OBS did not crash yet the video was still messed up. In fact, it happened again just yesterday.

Thanks for the info, Jim, I will look into it. The real issue is I need to do some editing with it before doing some uploading to youtube, which means i have to get it into a useable state. I will update once I've tried all of those things, but I did just download the 64 bit version of VLC and it didn't seem to help.

@vbdkv, maybe you could link the thread where you reported this, with example vod's/logs etc.
There are of course sometimes reports of people that have problems with playback or a broken mp4 after an obs crash, which is totally normal and why we recommend to record in flv, but I have not encountered nor am I aware of the things you mentioned. Recently someone tried to tell me that big video files wont work, while I record several hundreds of gigabytes without problems :)

 

[mdandrewm]

So I tried all those things and still no luck. Various mp4 repair programs/services online and such are capable of recovering frames from the video, but none of the free ones have come up with quality recoveries. The remuxing only threw errors about reading the file and my research online regarding those messages hasn't yielded a solution. I'd be more than welcome to provide the file, but i don't know if 5.28 gigs of video is easy to pass around (I imagine the upload a file option has a much lower limit).

Ohh that's gonna be hard, I always figured it was a random bug which it kinda seem like it is. However recently OBS got a new feature, a timer if you like, that gives it a bit more time to process the video. I guess that was/is the issue that people might quit OBS before the file is written properly. I don't know as it's very random.

The big video file thing is probably related to GPU encoding and Windows 7's file sink; http://msdn.microsoft.com/en-us/library/windows/desktop/dd757763(v=vs.85).aspx Naturally it's something that can be "fixed" in the recording software itself, otherwise I myself wouldn't be able to record huge files which I tend to do :)
