Hi Everyone!

I have a video file which according to the header is in AVC format, however I am unable to convert it to an MP4 or even playback on my system.

Is anyone familiar with the format I am dealing with ?

Any help is greatly appreciated.

Complete file is 1GB in size, a small section of the video 30MB can be downloaded here

I'm on a tablet at the moment, so I'm not going to download the file right now.

There are three tools that can help, they're all cross-platform. You do need to be discriminating about where you download them from, only download from the developers' sites, and only click on the actual links you want!

MediaInfo (external link) - will analyze your file, and give you more info about what format it is. Select one of the advanced views to see all details! The Mac App Store version has a small fee, but there is a free download on the site, too.
VLC Media Player (external link) - will play about anything, using the versatile ffmpeg library.
Handbrake (external link) - will convert to a vanilla MP4, using the best MP4 encoder out there.

AVC is a container format for h.264/MP4 encoded video. The three file specs are closely related, but, some manufacturers give them a bit of a tweak, as they are open specs.

These are three great tools I use all the time...

AVC is the common container for blu-ray authoring. It's hard to offer any more advice without knowing what software you have. If you're just looking to extract certain streams from the file (be it video, audio, subtitles)...there are freeware demux programs for that task. You're probably running into problems because it's not a single video file, but a container with several tracks.

Yes, correct AVC is container format. Tools mentioned can be reviewed.

VLC Media Player is unable to play the file in question. When I try to open the video, VLC window changes its size a few times, but does not display any video.

MediaInfo does not seem to show anything helpful.

Here is a little bit more info about my issue.

A 5 hour long video is hosted here
[Removed]

I need to cut out a small section of this video for the project I am working on. I recorded the screen with snag-it, but the video I got has a lip-sync problem and the quality is even worse than the original which is not great to begin with.

So I thought I could get the original video from IE cache and export the part that I needed without the loss of the quality.

Thanks

Edit: I was able to find and obtain the original mp4 file
