No AVC1 avi playback in quicktime

[roper]

I have read that quicktime should natively run AVC codecs naturally, however I am unable to do so, I have a 60MB Avi file that utilizes the AVC1 codec but I cannot open it in anything other than VLC, naturally this would not be a problem however I would like to make a reference movie file for this and cannot do so if I can't open it in quicktime, any help would be much appreciated. Oh yeah I have deleted the quicktime plist to see if that would help and apparently it didnt.

There are different levels and profiles for AVC. Quicktime is not able to open them all natively. Installing avc1decoder enables wider AVC1 support within Quicktime.

I have installed avc1decoder and still wont work, am I missing something?

Alas, even avc1decoder doesn't enable complete AVC1 support in Quicktime. You can try uninstalling, it then installing Perian instead, but I doubt it will work either.

Do you get any error message or just a blank/black window ?

I have perian installed aswell, prior to installing avc1decoder, the error message i get is The movie could not be opened.The file is not a movie file. However I can open it in VLC so i know it is a movie file.

I have QuickTime Pro 7.5 and it plays videos encoded in avc1Decoder very badly. The image is jerky and the audio is out of sync.
And I have the avc1Decoder component installed.
avc1 videos only play OK in VLC or QT Sync.
The curious fact is that all Apple corporate videos are encoded in avc1 and QuickTime can't play them correctly.
Does anybody has an answer to this problem?

Try this, it worked for me. Download and install the avc1Decoder, then choose your movie and change the filetype to mp4. For example, the file I had was an flv file (name.flv), so i just changed it to (name.mp4) and it opened in QT.

I was also able to convert it into an mpeg1 with Compressor.
