50Mbps of AVC-Intra for editing.

One day I was talking to a representative of a certain company about Panasonic’s implementation of AVC50 and AVC100. He told me that using H.264 on an ENG type camera isn’t a good idea because you need an over powered computer to edit that. We all know that it’s true but 50mbps of AVC intra shouldn’t be that much more difficult than editing 35MBPS of MPEG2 is it?


With AVC intra, you’re not dealing with a GOP like in the XDCAM so it should be easier but then again H.264 is more compressed.

Any thoughts?
 
The answer is to edit in Final Cut Pro 6 with the Apple ProRes codec when it is released in May.

AVC Intra's not out yet, so we don't know any firsthand answers. I would speculate that AVC-Intra would be *much* easier to edit than XDCAM HD, specifically because there is no GOP. But it may be a tad slower than DVCPRO-HD.

AVC-HD is quite slow to edit without some hardware assist, but AVC-Intra is an entirely different type of algorithm (no GOP issues) so it should be rather speedy.
 
That’s what I figured.

The representative got me confused when he told me that AVC-Intra will be a whole lot harder to edit than XDCAM.
 
Lots of people are confusing AVC-Intra and AVC-HD. Probably would have behooved Panasonic to choose a different name, but ...
 
Panasonic isnt to good at behooving, good names for things.....

like the whole, 1080i24pa thing. people get confused.

Huh? How is that even possible? I'm confused.

The image is scanned in 1080 at 24 progressive frames per second and then layed down in a 60i video stream using the 2:3:3:2 advanced pulldown method. In other words the progressive frames are split up into fields and recorded to an interlaced video stream. When you import the footage into an NLE using a 24p timeline and remove advanced pulldown, you have a 1080/24p sequence.
