[Paul Jay] “If you use CUDA based apps like Davinci, Premiere, After Effects then a Quadro is a waste of money if you ask me.”
I’m not sure I follow your reasoning…10 bit output isn’t important with Resolve?
If not CUDA, then what would you use a Quadro card for?

I think true “Future Proofing” is a bit of a pipe dream…but of course some methods would be better than others.
Saving your DVD and BluRay projects as ISO files is a good idea…for as long as burning optical discs will be necessary.
For a master file that could be re-purposed for whatever lies in the future…there are as many opinions on this as there are options. A frame sequence can be the most flexible way to save video, but audio would have to be a separate file (which wouldn’t be completely impractical of course) and the video file size for DPX or TIF files would likely be massive.
Production Profile H264 is the basis for AVC-Intra, XAVC, and even the very light compression in HDcamSR…so H264’s reputation as being only appropriate for video on cel phones is a pretty narrow perspective. So H264 is interesting at high data rates, but it’s still a version of compression and many really want to avoid compression in archive (though they also want to avoid buying petabytes of storage…), so many people find themselves in a strange conundrum.
H265 seems amazing in its early propaganda and demonstrations, but it’s early for most people to just make the leap this early.
I’m not one of those people that answer a question with a question…I seem to always come up with 5-8 questions.

It surprises me that you can’t trim it on a Mac with ProRes write capability installed (Motion or FCPX or whatever installed).
However, I know that Adobe worked on ProRes functionality for the next release, and I’ll be curious to see if that capability becomes available.
On Windows, our inherent limitations defined by an embargo on ProRes write and archaic 32 bit QT remain…however, I was running ProRes 4K on the Premiere Pro edit timeline on the floor at NAB in the AJA booth on a Windows system, and in my experience, that represents a notable performance improvement…thus I am hopeful.

[Robert d’Alexis] “FWIW, I imported a 3 hour 20 min long clip from my Sony PMW-350 which produces XDCAM EX files with 4 audio channels and the audio took 1 minute and 21 seconds to conform.”
That is probably a bit snappier than most, but I think that transcoding to an intermediate format still likely takes longer on any given system than audio conforming if the cache files are targeted properly (not to the system drive) and the machine has the drive space on a drive that’s fast enough…

[Sascha Engel] “But actually the conforming time takes longer than getting it inserted into FCP…so in that case FCP 7 is faster to work with those files.”
…as long as you completely discount the fact you had to transcode or rewrap the file to use it in FCP7 in the first place
(which is what I find most FCP editors do when evaluating Premiere Pro’s speed), then sure, you could say that.
I can’t vouch for your system…processor, RAM, etc…I have no idea what drive your cache files are targeted to, how full that drive is or how fast it is…
However if given the choice to transcode every single clip, tripling the data space the media takes up before I even start cutting, or importing native files and waiting for some audio conform…I suspect on a machine that is configured to do the work, this is still faster.

Two variables at work here…what softare is affected today…and what may happen tomorrow.
The Titan is the current shiny object of GPU lust…extra power is not often our problem in video post…but Jeff’s point about over-configuring one area and under-configuring elsewhere is also valid. The GPU is assisting with scaling and effects processing as well as color space conversions, etc. Decode is still a CPU thing…as is encode.
AMD is starting to really make some noise about their cards now that PPro ‘next’ will utilize any GPU card, but time will tell as to whether OpenCL is inferior, equal, or superior to CUDA in any given area, though getting a test together where all other factors would be equal would be nearly impossible…
Part of this will also have to be based on the power supply in your system as some of these large GPU cards have significant power draw, as well as heat production.

Excellent suggestion Jeff… You could set the values to change every frame and you’re set…
No question…faster than my original thoughts on it.

Greg may mean “tracks” like audio clips…butt-spliced together on the same audio “track” in the timeline.
Human ears don’t work with linear audio any better than our eyes work with linear light…the “Constant Power” audio transition will likely give you something closer to what you’re looking for.

[John-Michael Seng-Wheeler] “My personal guess is that it was actually the jump from XP to Windows 7. Apple didn’t bother making a decent version of Quicktime for Win 7.”
Assuming you weren’t running XP 64, the OS took that same 32 to 64 bit jump then…the same as I did. Few of my hardware drivers were even released for Vista.

[John-Michael Seng-Wheeler] “I jumped from CS3 to CS5 and at the same time switched computers. (both were windows.)
The exact settings I’d used before (usually 5Mb/s) were suddenly producing complete crap.”
Yeah…that was the Adobe jump from 32 bit to 64 bit…and of course QT stayed where it was, so Adobe had to develop that QT32server app to try to be able to even use it…
