failure opening canon cr3-file

Recommended Posts

When I try to open a canon CR3-file I get the following error message ( See attachement ). The file was created by my new Canon EOS M6 Mark II.
These CR3-Files are between 30 and 50 MB in size.
I would be grateful if this bug were fixed in the new version.

Hey KoBu,

As Joachim_L has suggested, it would be very helpful if you could kindly attach a sample so we can investigate. I've got lots of cr3 files and I don't have any trouble with the ones I have.

Bonjour Leroux,

dans la dernière version bêta, les fichiers cr3 normaux devraient déjà être lisibles.

Dans mon cas, cependant, c'est le nouveau Canon EOS M6 Mark ii. Cela peut résoudre des images avec 32,5 mégapixels. Cette haute résolution semble toujours poser nombreux problèmes.  L'équipe de développement sera certainement en mesure de résoudre ces problèmes.

For the record, I have the same camera and same issue.   

Does it change anything for you if you dial it down and shoot at a slightly lower resolution?  Haven't tried that yet and at work now.   Just curious.

Now here is a full-size RAW file that does not use C-RAW compression.  Like the Pillsbury Dough Boy used to say about their muffins:  THEY'RE HUGE!  :-)

Same result:  "The file could not be parsed."

Hey timlt,
until the developers offer a solution, the only option is to use
for raw files additionally the Canon Digital Photo Professional 4 (look at the homepage of Canon support software) (and finally convert the raw files to jpg).

Hey emmrecs01,

thanks for the hint.
I tried it out. I have converted a sample file (37 MB Raw) with the Canon software in different ways. Result: jpg 17 MB, tiff 92 MB, tiff 16 Bit 184 MB. 
I never thought the size difference would be that big.

Just me--I've tried the Canon DPP as recently as 2 weeks ago, it is a no-go.  Not only is the UI clunky and hard to use, the collection and file management features are virtually useless, etc.  But on top of that, DPP does not produce as good results with RAW files as I can get with other RAW processors that handle CR3 (including or especially:   Adobe camera raw/Lightroom,  Skylum Luminar 4, and now, Affinity Photo).   And worst of all, DPP is mind-numbingly SLOOOOWWWWWW.   Try this experiment:  take a batch of 20 good-sized RAW CR3 photos of 20mb each, or more.  Convert to 16-bit tif.  Time how long it takes.  Now perform this same test in ACR/Lightroom (if you have it), or in Affinity Photo beta.  It's not even close!  conversion times ranged between 10x and 15x longer in DPP, every time I tested.   Anyway, can you tell that I'm not a DPP fan?  🙂

Anyway good news for this thread and back on topic:  with the latest Afffinity beta update, CR3 works great and my RAW handling problems in the beta are fixed!   Hopefully @kobu you are now up and running as well.

No problems encountered (both files)
Using the latest beta - 1.8.0.555
Both files open and develop error-free.

Greetings,
Hubert.
