Quicktime codec problem?????

[Riversound]

Hi people.
I have a quicktime video.
A friend give it to me in HD mov.
I cant reproduce the file.

"error 2048 in quicktime"


Is a video extraction from the Adobe Premiere.

The mediainfo program say about this file:
Formato: MPEG-4
Formato del Perfil: Quicktime
ID codec: qt

can somebody help me??

sorry for my english.

What do you play it with? tried vlc media player?

[sum_guy]

I would try mediainfo and see exactly what kind of file it is too.

[Riversound]

Im using VLC and nothing.
And the mediainfo program say about the file:
Formato: MPEG-4
Formato del Perfil: Quicktime
ID codec: qt

and nothing more. ¿It is corrupt?

Copy the file to a new folder ... always work with a copy and never the original

I just had the same exact same problem. I was able to fix it though, so hopefully one day someone will have some use for this. I know this is an old thread.

I had recorded 4 clips on camera, but the video was vertical. I opened the video with quicktime cause it was a .mov container. I rotated the video 90 degrees and saved it.....not SAVE AS. After that my video wouldn't play at all. I knew all the data was there cause of the file size. I looked the meta data on a qt atom viewer and compared it to my other clips. I found out one of my moov entries weren't there. So the corrupted line looked like:

4483800: 00 00 11 BA 66 72 65 65-00 00 00 6C 6D 76 68 64  ....free...lmvhd

If you look up lmvhd you can find this entry. So I just changed free to moov in hex editor provided by vdub and it started playing. For me there were 2 entries for moov on all my files.

Error -2048 stands for "no movie found".
See http://aeroquartet.com/movierepair/quicktime-errors

The tip mentioned by mrcoolekin above will work only when you have a new moov atom appended at the end of the movie file, that supersedes an older moov atom (replaced by free, thus ignored by quicktime)
In this case you don't have err -2048, but rather a good quicktime but with missing content.

For -2048, the most frequent causes are:
- Missing resource fork, http://aeroquartet.com/movierepair/missing%20resource%20fork
or
- Video file without moov atom (corrupt file needing re-indexing).

I would suggest that you try to preview your file with http://mp4repair.org and depending on diagnostics result, decide best course of action.

Of course QT uses codecs, but the previous problem mentioned had NOTHING to do with codecs, it had to do with the header missing a certain sequence (moov) that designates that a later segment is a Quicktime Movie file (.MOV) with video and/or audio (or other) tracks in it.

That could probably have been avoided by NOT doing a Save, but a SaveAs, and also avoiding making a Reference File (QT file similar to a shortcut/alias).

Your problem, OTOH, who KNOWS?!!
First thing you should do is look at the beginning of the file in a Hex Editor and post the ~first 100 bytes as a text output.
Then, open the file in MediaInfo and post the text output of it.

One or both of them will make it clear whether this is a QT file or not.
If it is, but something's wrong, you should look at QT files from within "Atom Viewer" (see Apple's website). This will give a clear breakdown of the internal structure of the QT file.

After you've posted, we might be able to help further...

Hopefully, you are NOT DL'ing warez, though.
