ALL-I and IPB Video Compression on Canon’s 5D Mark III

5D Mark III

This is no real surprise at this point; however, a leaked review from a French publication confirms that the Canon 5D Mark III supports intraframe (ALL-i) compression for an editing-friendly format and interframe (IPB) compression for superior data compression.

Based on what we’ve seen thus far, it’s likely that the 5D Mark III video specs will closely resemble the specs found in the 1D X.  Note that the 1D X allows level monitoring on screen and adjustments to audio levels before and during recording of video clips.  The presence of a headphone output suggests that the 5D Mark III will take this a step further.

Jury is still out on the HDMI-out; however, there have been no leaks concerning this spec and pretty much everything is out in the open now.  Stay tuned over the next few hours for the official unveil.

What we’re expecting is the Canon 5D Mark III – a 22MP full frame DSLR that captures 1080p video with the same codec we see in the 1D X (edit-friendly ALL-I and the more compressed IPB). [Read more…]
