Title: Importing in EM2 on new mac pro
Post by: dave robertson on April 30, 2009, 09:07:27 AM
Hi, I've been using EM1 on a G5 and now run it on an 09 Mac Pro, it works fine, but importing of Phase One raw tiffs and tiffs with lzw compression now seem glacially slow.  This isn't news but in comparison with everything else on this machine it really stands out.  Will EM2 import these files significantly quicker?

Many thanks,
Dave

I'm new to the forum, don't know how active it is.  I'm interested in anyone's experience importing the files mentioned, whether there's been any attempt to optimize for the mac pro platform, new or old, with EM2; or do the files still import rather begrudgingly.

Thanks,
Dave

Dave,
I don't happen to have any Phase files to test with.
There are some settings that can affect how fast files are imported, but I'm not sure how Phase files are built, so I can't say for sure what the right ones are. I'll ping Microsoft, and see if they can be of assistance.

Thanks Peter, I should probably do that then if there's no one managing those files here I'm posting in the wrong place.  But perhaps you could reply back re photoshop tiffs with lzw compression as that's the other format I find imports slowly.

Cheers,
Dave

Dave,
I'm pretty swamped to do any extra testing right now.  I generally don't use compression on my TIFFs, since I'm happy to trade extra size for speed.

Expression is using Quicktime to decode the files on Mac (and often on PC as well), so that's *probably* the speed limiter for TIFFs.  And remember, unless you tell EM to use embedded thumbnails, it's going to need to open, and then create a downsized version of the file in order to make a thumbnail on import.  How long does it take Preview, for instance, to open the file compared to Expression importing a file?

You also may want to try to import with different preference settings for Media Rendering. For raw files, there is a way to tell the program to use embedded thumbnails. Works great for DNG and really speeds up the process. For proprietary raw, the entire file needs to opened up and decoded from mosaiced raw data. .  I know there is new code in EM2 specifically for Phase 1 files, but it could still be slow, since the files need to be opened, and that's a fair amount of math.

Have you tried downloading the demo of Expression 2 and trying it on your setup?

Peter

Thanks for the advice, Peter.  The Phase One raw file previews are opened instantly in Preview as do the lzw tiffs, whereas they import slowly in EM1, and I've noticed Hasselblad raw files import instantly in EM1 but show nothing in Preview, so there does seem to be a very mixed bag of standards out there.  My preferences are set to use any available preview.  I'll look at the EM2 trial download as you've suggested.  I've been hesitant as my initial impression using EM1 wasn't good and elements of it persisted after first trying it and uninstalling a couple years ago and I'd like to avoid a repeat.  Of course I've since adopted EM1, at some point you just have to start swimming with the tide.

Cheers,
Dave

Dave,

What's the media rendering preference - manufacturer or Apple? If the files open quickly in Preview, Apple may be the better choice here.

Hi Dave,

Firstly download the trial and test for yourself as recommended.

Expression Media 2 is noticeably faster than v1 or iView because it is multi-threaded. The latest Service Pack 2 includes better support for Capture One Raw files. Most probably because of the Phase One/Microsoft "Better Together" partnership.

It's set on Apple but I've toggled this option and it doesn't appear to make a difference.  The multi-threading in EM2 sounds encouraging, I think that's what this computer likes so I'll give that a whirl.  Thanks for the feedback.

Cheers,
Dave

Unticking "use alpha channel" in the raw rendering preferences did the trick, I don't know why that has any bearing on Phase One raw files but apparently it does.  And I'm not sure why I would have selected that in the first place, is it the default?  Anyway I've done some poking around in the EM forum and it looks like they're up to their old tricks with sp's, rollups and hotfixes in v2, already went through all that with v1 I'm very happy I won't be needing to go there.  Thanks again.

Dave

Hi Dave,

Thanks for reporting back. My guess is Expression Media is seeing the Phase One files as vanilla TIFFs and not Raw files.
