Hi all, in my OP i already wrote:

I noted that Canon RAWs from some new cameras show the ending ".mp4", as for a video, but they don't play as video in VLC.

When i rename these Canon Eos R5 RAW files to "*.CR3", they do display ok in ACR

I thought this makes clear that i'm aware of the meaning of MP4 vs. CR3/CR2. I just wanted to know why the Canon files show up as MP4s and if they can be considered authentic or if i should try to find some undoubtable CR3s elsewhere.

You could try to download any RAW file from the Canon R5 sample gallery, for me they all seem to arrive as MP4, but can be re-labeled to CR3. You can try for instance this direct link (link to Canon R5 RAW file copied from DPR Canon R5 gallery):

https://s3.amazonaws.com/files.dpreview.com/sample_galleries/7757595702/0895017892.cr3?X-Amz-Expires=3600&response-content-disposition=attachment%3B%20filename%3D%22012A0507.CR3%22&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIA4NPXSRZN2I2XWOXX/20211013/us-east-1/s3/aws4_request&X-Amz-Date=20211013T185547Z&X-Amz-SignedHeaders=host&X-Amz-Signature=cf169e724219f97fdd717864ebe37dfd3eb0eeda38a6b7fee7541bd9769ac026

There's even "CR3" in this link above, still in the dialog "Save file as" it's MP4.

The above download link is from this gallery page:

https://www.dpreview.com/sample-galleries/7757595702/canon-eos-r5-sample-gallery/8277337580

Offers me a .cr3 either from the direct link or clicking on RAW from the image.  Something funny with your browser settings?
