DCI - 2K files playback

[edo1080]

I've got a DCI compliant file with .qcc extension , but I'm not able to get it played on PC.

Look for the following on binsearch.info

CH1_LEFT_1KHz

The file is not encrypted so it doesn't require a key to be played

To see files properties there's a free tool by Quvis:

Among QuApps there's a tool named QuClips which should ideally let you decode the clips, but the only thing I've been able to do is to see clip properties. More Quvis tools can be found here:

and useful informations about Wraptor plugin for final cut studio here :

I would like to play it on my PC; as far as I unterstood it could be opened in final cut studio on Apple computers (Wraptor plugin could lead to think so) but I've not an Apple computer

Even if it looks PAL only, it has the same encode as 2K 2048x1080 files.
It is a test file for front left channel.
I haven't been able to play it on PC but it plays smoothly of course on every Digital Cinema Server (Quvis, Doremi, Dolby....) ; it seems to have been encoded in MOTION JPEG2000 and there's a codec for windows named Morgan Motion JPEG2000 codec but I haven't been able to get it work

qcc is not a popular extension anyone would recognize, the file properties info for what I can tell is unfortunately useless and at least I don't have access to binary newsgroups (and probably many, many others don't have either).
You'll have to either dig up more info or find a more convenient place to upload (it really isn't a large file after all, in the worst case even the first few MBs would probably help).
Some hints as to which players you tried with which results would be a good idea, too.

Well, at least it is not DCI format, that one is specified here: http://dcimovies.com/ and uses MXF which this file definitely is not.
Does that format have any real name or even a specification?
It is a rather strange format and I doubt that anything else supports it, it looks quite a bit vendor/application-specific.
Why do I think so? Because of the strange padding, every section start is aligned to start at a multiple of 64 bytes, the index-like stuff is aligned to even 512 bytes (a typical indication that it was optimized for fast disk access which makes little sense for general-purpose formats).

Yes, it looks so.

I made a clean windows installation, and tested the tool QuClips inside the Quapps package. This time it worked; I have successfully been able to decode video into single frames. Using The decode funcion of Quclips, I can obtain single frames in either Tif 16bit per component or DPX 10 or 16bit , it should approx match the source quality. Since as you confirmed the format looks a Quvis one, there's no way to play it on PC, anyway the tif frames can be re-econded in a Motion JPEG2000 for windows with FULL GAMUT!!!!!

The same tool QuClips allows to extract single mono was tracks from the 5.1 raw pcm mux of the file.

At the end we have motion jpeg video track + 6 mono wavs...

I'm trying to mux them into MXF (Motion Jpeg2000 a+v container) and if it works it's done... Thanks for your help
