  2. The Third Image

    ... I’m still not following what point your trying to make. What we can do now in the digital world ...

    Thanks for your lesson on digital images, but there is no need for that. By the way, I like the way you create montages in Photoshop. The question one may ask is: How many PTE users will apply your techniques?

    You have called this topic "The Third Image". I don't see much correlation between your externally created montages and the so called "Third Image". In my opinion, this kind of image automatically appears when blending together images, and such a (virtual) image can look good, or perhaps not so good. In my example, Alpa-Blending does a rather bad job. In this situation, if there were "Screen" at hand in PTE, I could create a nice Third Image on the screen/monitor, on the fly, without doing any unnecessary work in an external image editor.  

    As I said above, I like your montages, and I know a lot of fine AV productions that use similar techniques. But there is a disadvantage, as well. The montages are static. Wouldn't it be fine to have blending options in PTE which could be applied to animated images?

    What photographic effects are you referring to and how are they significantly better than what we have digitally? I’m not following you here

    1. We may look at an example. There are 2 images that are (to some extent) complementary in brightness (first row).

    2. The second row shows 2 mixes. On the left: a mix using the blending mode "Screen". This mode is regarded as the digital analogue of blending photographic slides (additive mix on a screen). On the right: Mix of the images with normal "Alpha-Blending" (both images contribute 50%). The version using "Screen" looks significantly better!

    3. In the third row we see a mix using Alpha-Blending while the transparency of second image is controlled using a mask (shown on the left).

    2 Mixes: Blending Mode "Screen"  and  "Alpha-Blending. The Screen-Version (left hand side) looks better.

    ... Years ago I submitted a suggestion for layer blend modes in PTE (overlay, multiply, ...) ...

    You are not the only one has asked for this feature  :)

    A (little) disadvantage of modern AV programs is that they implement the dissolve using alpha-blending (which is a weighted arithmetic mean value). So without using masks you cannot achieve effects that we had when blending photographic slides, where we had two projectors and an additive mix on the screen. The blending mode "Screen" gives us an effect that is (to some extent) similar to classical blending. Sometimes, I would like to have in PTE :rolleyes:

  6. Images too saturated

    in General Discussion

    Posted

    What is the colour profile that is used by your monitor, is it AdobeRGB? An sRGB image typically looks oversaturated on an AdobeRGB monitor when using an application without colour management. Lightroom and Photoshop are colour managed, while PTE 8 is not. Here, the colour profile of the images and the profile of the monitor should coincide.

    I created the claps with a USB-Mic in Audacity (version 2.3.3). The mp3 file has been exported from Audacity.

    I noticed this problem when I used V10 to open a show created in V9, and which runs fine in V9. The problem happened with an mp3 file exported from Audacity (2017), containing a mix of edited pieces from an Audio-CD. Attachment: Media-Info of this mp3 clip.

    In both cases I used the option "Joint Stereo" which normally works well for me.

    It seems that choosing long start times for audio clips will cause time shifts in PTE 10, while PTE 9 shows a nice behaviour. You may look at the attached example project, which contains an audio clip with a start time of about 4 minutes.

    1) Open the attached project in Version 9 first. Have a look at the transition points and at the audio peaks in the upper audio track. Run the show in the preview or in the Mini-Player. You should see and hear what you will expect. The 2 colour changes and the 2 claps show up at the same time. Close without saving.

    2) Now open the attached project in Version 10. Again, have a look at the transition point and at the audio peaks in the upper audio track. Run the show in the preview or in the Mini-Player. In Version 10, the colour changes and the claps do not come together. The claps come too early. In order to have colour changes and claps at the same time, you have to mute the upper audio track and unmute the lower audio track. In the lower track, the peaks in the wave are far away from the transition points.

  15. Question on output format

    .....

    Settings as per jt49 's advice (H.265 - 3840x2160) at 60fps: File plays fine on TV. TV specs say max supported framerate for H265 - 3840x2160 is 60. So that's ok for me as well. File size is 1.90 GB. Encoding time way over 30 mins.

    Using Handbrake to transcode a AV 10 exported file to H.265 - HD 1920x1080 at 30 fps. OK for TV. File size 29.3 MB.

    .....

    1.9 GB sounds odd, perhaps unfavourable  parameters. Try "constant quality" with RF between 18 and 23 (smaller numbers give (theoretically) better quality, but larger files).

    Sorry, but I can't get Handbrake to output 3840x2160 with HEVC H.265 codec. It always reverts to 1920x1080.

    Use HB version 1.3.1 which is the latest IIRC and tested with a AV Studio 10 exported mp4 file (sample project) 3840x2160, 20Mbps and 25 fps. 

    I use the same version of HB

    Settings for transciding:

    Tried it, problem however is that it looks like Handbrake doesn't allow the combination of H.265 with 3840x2160. It reduces res to 1920x1080.

    XMedia Recode is new for me, had a quick look at it but didn't try it.

    It is known that Handbrake cannot upscale. But if the original Video is 3840x2160, Handbrake can trancode it to a HEVC-video with the same frame rate and the same dimension (3840x2160). I have just made a test, choosing constant quality, RF=18. Remark: I would recommend to choose "Always use mp4" in: Preferences > Output Files.
