Please try the new Test Color Management 3
3. Transformation of ANY JPEG images to current color profile of your display.
Sorry Igor, I missed this step before.
The result of my tests with your Test Color Management 3 are in accordance with that.
PicturesToExe will perform automatic color management by default. Users need to change anything
So in this case that will be perfect for me.
Thanks.

Picsel,
Just had another thought over your results and actually replicated your results. It seems, that your wide gamut monitor has correct profile assigned and both test programs, Igor made, understood it correctly. You actually used dog image with sRGB profile to test color management. However, when you uploaded your sample image to the forum, you reworked it in Photoshop and saved without color profile.

thanks for making some tests but if you are right in principle your tests are wrong, that is my fault, I must apologize for that.
In fact when I said "original picture" that was not right, that was a print screen of the original picture saved with pixbuilder.
The original picture was in sRGB, and I made the test with my original picture and obiously not with the printscreen.
Most of the cameras, and "digital" screens are in sRGB which is a de facto standard for displaying pictures.

Daniel,
You used previous test application. It works incorrectly in some cases.
Please try the latest version I posted yesterday:
https://dl.dropboxusercontent.com/u/27544810/pte/Test-Color-Management-3.zip
Hi Igor,
After testing your latest version, I cannot see any differences between the three modes with my pictures which are all in sRGB;
For my understanding, if you intend to work with color management I would like to know if it will make conversion from 8bits coding depth to X bits (and so in this case, is X a setting parameter)? And, in which color space will the pictures be converted by PTE.
I just want to draw your attention on the fact that, up to now, few people know how to deal with color management and for the others I fear that color management option in PTE will bring them some more problem without a great interest for them due to the fact that, today, most of the displaying screens are still in sRGB for a while (I think, it will take time before the UHDTV becomes widely spread as there is no interest for common users except the color space).
Personnaly I would prefer a color management option which could be able to switch all the slideshow from sRGB color space to YUV or UHDTV for example in order to avoid to modify the color settings of video projector or TV set.
Best regards
Daniel

Igor, sorry for being late to answer your question, I made your exercise with one of my own picture which was re-worked in photoshop.
My conclusion is : with your test, the color management gives me a bad result : see attachment bellow.
My personnal opinion : it is not easy to work with color management, except for some experts. I would leave that job to Photoshop, or other picture editing software.

Robert,
just for your information
I ve recently made an AV show whose the total size of elements (including audios, videos, pictures ) was 2,7Go
Using PTE v8.0.0 I have created an mp4 (h264) video of 1,6Go without any problem : 1920x1080 in HQ 16Mbit/s 25fps (european std).

Just for information.
I agree with Jeff, PTE (even v7.5.10) is able to manage AVCHD files with MTS extension. There were a lot of improvement which has been done by PTE team on this subject.
The MTS file can be played within the PTE mini-viewer and converted in AVI (mpeg4 ASP by PTE videoconverter). Even if there is a slight loose of quality by converting H264 AVCHD in Mpeg4 ASP, the result is quite good and ease the work of video editing after without requiring too much power processing.
By comparison Premiere Pro is doing something similar, up to CS5 (I have no experience with CS6). In fact Premiere Pro converts all the AVCHD files into MPEG video files for the video editing process (In that way, we can say Premiere Pro CS5 is not ACHD compatible either). And Premiere Pro requires much more times for rendering. It is easier and far less time consuming to do the same job with PTE for the same or even better quality result.
Daniel
PS : I agree with Lin there are small differences between M2TS and MTS files but for those who use cameras or camcorders, the original file embedded in AVCHD containers : /BDMV/STREAM are in MTS. They are converted in M2TS by players or intermediate softwares like Sony Picture Motion Browser in order to link all separated MTS video files together for playing on TV set.

Congratulations Igor to you and all your team members.
Santa Claus has gone just before Christmas this year!
That is a very important challenge for PTE future, I wish you all the best and all the success you deserve.
Have nice Christmas holidays, some rest is well deserved after this period of huge work.
Best regards

BRAVO!!

I'll rephrase:
IN ITS CURRENT FORMAT Pte does not recognise or anticipate the user's BG during a transition.
If that's what Daniel wants then a suggestion for a change is what is required?
I would endorse it.
DG
Dave,
except if I have misunderstood your comment, I think that is not true!
If you use 2 slides with the same background and make a transition effect between them both you never see the black background and that is a normal behaviour for all editing softwares I know!
In fact I posted here a question raised by one of our forum members. I thought there were a very simple solution I had forgoten that was the reason I wrote "just for an help". But as there is not easy solution for this very simple problem I think an update is required. Obviously that is up to Igor to decide.

Dave, Lin
thanks to you both for your work and solution. Personnaly I found that Lin solution is closer to the 3D swap effect of PTE. Lin did you build a customize transition too?
Dave I agree it works like that but in fact you confirm what I thought : there is no simple way to do that for common PTE users "without making too complicates things like customize transition or slide styles" refering to my first post.
The question : why the background, selected by the user, for the slide is replaced by a black one during the 3D transition effect (swap)? remains unanswered.
I can guess that Igor has edited this transition effect longtimes ago. An update could solve this issue for PTE users who can consider, now with V8, it does not work as expected with other backgrounds.

Hi Daniel,
I took one of the 3D samples Igor provided and modified it with a new background image of my motorcycle. Then I used that same motorcycle image as the default background for this sample show and set the "transition" to the modified 3D transition. Actually, it's pretty easy and quick to modify the transition with your own background image so maybe this will work for you. Here's a link to the sample. Let me know if you have any questions about modifying the transition.

Hi Lin,
sorry my previous message was post before I read yours.
I will try you suggestion and come back to you after that.

Hi Yachtsman1 and Lin
Thanks to you for helping me to find a solution to this clue.
Sorry for my bad english which apparently could be understood in different ways, but Lin understanding was the right one.
Hi Gérard,
I tried your suggestion but that does not work (except if you completely rebuild the 3D animation which is not my purpose there)
Even if I select a background for screen inside the Project Options/screen/background/image, it does not work either
In the all cases the background image is replaced by a black background during 3D transition effect (swap).
Quite difficult to understand why the background selected by the user is not taken into account during 3D effect...??
Daniel
-
Hi Lin,
thanks for your reply
That was the conclusion I reached too. But that is a pity PTE does not use the "Slide option/Main/Slide/Use own background preference" function to do that very easily.
When I select a dedicated background for a slide I am expecting that background remains and will not be replaced by a black one..that is a suggestion for Igor.
Except if I am wrong but, making a customize transition, I have to rebuild completely the 3D animation, that is neither very efficient nor very satisfying, but if there is no other way...
best regards
Daniel

Just for an help
I would like to know how to proceed in order to keep the same image background during the 3D transitions, avoiding to see background in black?
Do you have an idea (avoiding to make too complicates things like customize transition and slide styles)?
Thanks in advance

Daniel,
Beta 10.
KFSD and Scale KF on.
Dave,
thanks for your exercise, playing with different options you succeed to get the good result but it does not solve the main problem!
I will post my answer in bugs report that will be easier for Igor to follow.
Daniel

I find it extremely difficult to follow these complicated instructions. Can you not post a backup in zip with blank rectangles to keep file size down??
Perhaps someone can recognize the issues.
DG
Dave,
Sorry but it is not so easy for me to explain as it is for you!
I would say, that is the case of most of posts on this subject, always difficult to follow as there are now a lot of options with this stuff!
I am very worried with that. In my opinion, many of PTE users will be completely lost with all KFSD or NKFSD options (Project/slide/O&A..., I fear that is not the good way to give it a good image. Only some experts will be happy with that.
Coming back to the subject :
The problem comes when the last KF is exactly at the ending point of first slide and beginning of transition with the following slide.
In such a case whatever the modification of the duration of the slide this KF remains sticked at this transitionnal point. That is not satisfying as it modifies the animation without advising the user that something goes wrong.
-
Hi Igor,
this new version solve some problem I had pointed out with KF but in my opinion it remains one problem :
Example :
3 slides 7s duration /3s effects on the slide line
(initial conditions = Non KFSD, without using scale KF).
on the slide n°2 I build up an animation :
zoom in from 7000 to 11000
then opacity change from 11000 to 14000 (last KF)
- First test :
I modify slide n°2 duration to 10s (ie +3s)
what I was expecting :
zoom in remains from 7000 to 11000
opacity change remains 11000 to 14000
leaving 14000 to 17000 free of any KF
but what PTE does :
zoom in 7000 to 11000 that is OK
and opacity becomes 11000 to 17000 which goes wrong!
(without advise to the user which is not satisfying )
That could lead to various errors.
Everything is OK only if the last KF is 13999 rather than 14000
- Second test :
I modify slide n°2 duration to 4s (ie -3s)
this time everything is OK .

I just tried Film strip, right now, it is a very interesting one and works perfectly well.
Thanks for sharing

Thanks Igor,
Good Idea, could solve the remaining issue with keyframe...I will try it.

Adding Blur to a full screen image creates what looks like a drop shadow right at the edges, which I find distracting. You don't get this effect when adding blur in image editors and I don't like the effect, it looks like a mistake.
Can anything be done.
+1
But I agree with Xaver, that requires a new blur option, meantime I still will use Photoshop.

I can get a resolution of 1% EASILY after using CTRL + SHIFT + Mouse Wheel to get the Maximum height for the Track on my 1280x800 Laptop screen.
Dave
Sorry to disagree with you and to insist on this important feature.
First of all on my 17" screen the 250% audio track height is 4,1cm. 1% of that is 0,4mm. The standard naked human eye can separate 2 points if their distance is more than 0,1mm for a vision at 30cm! So you are right, you should be able to see these 2 points but on a 17" of 800px height the difference between these 2 points is only 1px!! So you said easily?
But that is not really the main point.
I maintain that it is impossible to make a correct setting for the low level audio volume. The total amplitude corresponds to 24 or 16bits depending of your audio codec. With a 16 bits codec you get 65536 different levels. With the compression law, in order to keep the S/N ratio roughly constant the most part of these levels concerns the low level part of the audio signal.
And so if you want to make an accuracy setting you need much more accuracy for low level signals than for the high ones.
See the example bellow you will see that there is no possibility to set the volume correctly. These type of audio files are very common for all AV makers who are used to deal with video clips.
On the other hand, if Igor wants to enlarge PTE market shares, he must offer a product at the same level or higher than other competitors and not behind.

I can easily get a resolution of 1% this way on a 1280x800 Laptop Screen.
Dave
you are alone!
The problem is even more important for low levels than for high levels due to the logarithmic compression law!
You need much more accuracy at zero crossing levels than for all the other levels of the waveform.
I think that is not a good idea to let think Igor and team that it is OK!
All AV editing makers know perfectly well that it is clearly a weak point and other AV editing softwares on the market are able to provide a wider range of amplitude.

Igor,
That is time for you to take a rest!
Have a good trip, enjoy the Greece, a beautiful country with so many things to see and to taste : people, food, islands, ancient monuments...

Test of Color Management
in General Discussion
Posted
I want to add some comments about color mangement.
We, in our club, have very few problem with color management between jpeg pictures and display screen as, in most cases they are all working in sRGB color space.
(We made bad experiences with calibration : expensive tools, spending too much time, repeatedly, for a very very little different result and not always in the good way. Calibration is required only for printing.)
Our main concern in fact, as I said in a previous post, is the difference of color settings of video-projector or TV set between videos (YUV) and Slideshow (sRGB) displays. In other words, I would say, if the color settings of the sRGB monitor are acurate for exe slideshow (sRGB), they are not for videos (YUV) and vice versa.
When we make a screening session, we often have a mix of videos and exe files and it is not always easy at all to find the good "average" color settings for each category so, assuming this problem is due to YUV/sRGB color space difference, it would be very interesting, if it was possible, to have an option to switch from one color space to another in order to avoid to modify color settings during the session.
