COPro v3.7 Preview draw times / 1Ds2 files
It strikes me that the preview draw times of already constituted previews is slower on the present version than the preceding official release for 1Ds2 files. This is a cause of concern as there is a marked lag in preview appearance that was previously much less pronounced. Unfortunately, I no longer have a backup v3.6.1 which I thought I did, but would not mind reverting back to the earlier official release if possible. I'm running on OS 10.3.9 and my system details have been provided via program feedback.

Well, it does not appear that this question is worthy of receiving any response from support. 0 -
I'm having the same issue, any fix to this problem yet? 0 -
Thought I'd look around and see if anyone else was having this problem while I'm sitting here waiting and waiting for 86 previews to load on a Dual G5 with 6 gigs of memory. It would appear I need a faster computer. 0 -
I'm currently waiting for 219 thumbs to render. I've been waiting for 12 minutes now and it's nowhere near done. This is really a bad bug and I hope that someone at Phase One can help soon. I'm losing hours of work as I have nearly 500 images to process.
I use Capture One Pro 3.7, Mac OSX 10.3.8, PowerBook 15\", 1 gig ram, 1.25GHZ G4.0 -
Most common here is that if you upgrade from 3.6 to 3.7 and open an existing session, you expect the previews to show up right away.
The fact is that 3.7 needs to regenerate previews for all the existing session where previews where generated under previous versions.
Once they are generated done under 3.7 the speed for showing previews is practicly the same.
Reason is that the clipping of a few pixel lines which was present under 3.6 is fixed on the Mac platform.0 -
I haven't done many tests with 3.6 versus 3.7, but I can tell you that 3.7 is significantly slower than 3.5 in the generation of thumbnails and previews for new (i.e. not revisisted sessions) 1Ds mk1 files. I haven't been able to pin down why.
Also, the manipulation of images is slower in 3.7 compared to 3.5. By manipulation, I mean the responsiveness to dragging sliders in, for example, the exposure tool.
I suspect that this problem may be due to the removal of the preference for \"Preview Display: Optimize drawing during live feedback for ...\" setting that was present in 3.5. With this set for Speed, the preview display whilst making slider adjustments showed a very low resolution, blocky image. This was actually all the feedback that was needed for making slider adjustments and they occurred quite rapidly using this system, even on an old G4. Once the slider was released, the preview would be updated to show a more detailed, higher resolution image.
When you make a slider adjustment in 3.7, the adjustment also occurs on a lower resolution version of the preview. But the resolution of this preview image is much higher than the one used in 3.5 when the Optimize preview display preference was set to speed. Now if I drag a slider in 3.7, there is a clear delay whilst the unnecessarily detailed preview is being updated. The result is that the system no longer responds rapidly to slider changes and feels unresponsive and awkward.

My normal test computer is a Mac G4 laptop, 1.33Ghz with 512mb RAM and a 3700rpm disk with Mac OS 10.4.1, hardly what I would call a monster computer.
Here slider adjustment are instant and preview generation is about the same as 3.6.
To dig deper could you create a support case at http://support.phaseone.com and attach a system profile and address it to me so we can try to see what is going on.0 -
Ulf,
As I mentioned at the top of my message, my benchmark for comparing speed is version 3.5. Rough tests with 3.6 on my system suggest that its speed is similar to that of 3.7. But both are slower in thumbnail and preview generation compared to 3.5.
As regards to slider responsiveness, I believe that 3.5 was the last version with the Optimize preview drawing preference.
If you can get hold of a version of 3.5 and set the preference under General:Preview Display:Optimize for Speed, I'm confident you will see a substantial difference in slider responsiveness compared to version 3.7
Thanks
Jason
(PS if you need a version of 3.5, I still have the 3.5.2 installer)0 -
It took a very, very long time, but I thank you for the responses. I should have been more specific. I am referring to a situation in which previews have already been generated. When switching between images in a given capture folder in order to effect a comparison and select an image for conversion, there is a noticeable lag in the appearance of the clearly defined preview on screen (in v3.7). This lag on my system is greater than in preceding versions, and is disturbing to me. It makes carrying out comparisons highly problematic.
On the other hand, I have no difficulty with tonal or color corrections which occur in real-time and smoothly.0 -

It hardly seems like a "fix" when I have to sit & wait for over 30 minutes to have the thumbs redraw. As I previously mentioned I have over 500 images to process and they are in nearly 100 different capture sessions. I cant use 3.6 because it always crashed. This is a huge bug and needs to be fixed. I had no problem with 3.5 but these last 2 versions are really not upgrades and I feel like I should be allowed 2 further upgrades at no cost appart from the one I have left.
Unfortunately this makes a great peice of software totally unusable for me right now when I need it the most. I use Capture One nearly every day for my work and while I still think it's a great tool it seriously needs to be better beta tested before new versions are released.0 -
Ralph: Apologies for hijacking your thread, as it appears we are talking about slightly different issues. I hope that your problem receives an official response quickly, and that you will allow our continued discussion on a slightly different, but probably related, topic
Kenk: It sounds like your experience is the same as mine: namely that performance has deteriorated signifcantly since version 3.5
Ulf et al: Please try a test of version 3.5.2 against 3.7, with the preference Preview Display in 3.5.2 set for Optimize for speed. Test:
a) Time required for thumbnail and preview generation for new files
b) Image manipulation and slider adjustment
c) Processing of images (using the old noise reduction method in 3.7)
On my system, 3.5.2 seems turbo charged in comparison to 3.7. I would be interested to hear your experiences,
Jason0
