By introducing in 2015 its 4K format called XF-AVC, Canon gave itself a second chance to catch Sony in the war for 4K dominance.
Ironically, the "new" XF-AVC is so similar to Sony XAVC that it takes some effort to distinguish them: Like Sony, Canon proposes a H.264/AVC based format wrapped in MXF files, and rebrands it as: Canon XF-AVC
Vendor: Canon Models: Canon EOS C300 Mark II, Canon XC10 Status: Treasured (version 3.4 and above) detects and previews XF-AVC recorded by those cameras.

Failure Modes
The causes of failure reported by Canon XF-AVC users needing to repair files are:- Loss of power during recording
- Device was turned off during recording (clip not finalized)
- Accidental deletion of MXF files
- CFast or SD card has been formatted by accident
- MXF files recovered (through undelete or recovery utilities) are corrupted
- MXF footage doesn't preview in Canon utility
Repairability
Treasured (since version 3.4) can detect Canon XF-AVC footage in recovered files (regardless of extension), in cards and in hard disks.
