  3. Z order keyframes

    in Suggestions for Next Versions

    Posted

    Hi MUR,

    Very nice. The only problem I see (that might be easy to fix) is at time 22 seconds with blue (azul) and purple (morado) color mix. I think it would more purple and less blue. Having 3 or more objects/layers mixing together is complicated to follow even when using video toolbar. I like you method and will try it in the future. :)

    Thanks,

    Tom

  7. Z order keyframes

    Hi MUR,

    From my limited understanding there are various methods to simulate correct Z order such as show front side only (rotating cube), switch transparency on/off, and multiple slides. It is hard to correctly display semi-transparent objects on one slide without drawing the objects in the correct order.

    Thanks for your demo slideshow. It is much more sophisticated than my versions.

  11. Z order keyframes

    It would be nice if we had a new keyframe property to move layers up or down. This would be a manual method of adjusting for hidden surface removal without requiring Direct3D or hardware graphics function. It would be compatible with all operating systems that PTE supports. It may not fix all Z order problems but it would fix the simple ones like the one in the video below. The demo slideshow utilizes 4 slides to simulate layer moving at keyframes. I have not tested to see if it accurately models transparency but in theory it should since the layers are in the correct order.

    Thanks,

    Tom

    Update: Z-order transparency test. It appears to be accurate.

    Peter,

    Well, it's acceptable for PicturesToExe itself. But what to do with EXE shows?

    Since PTE slideshow objects follow a fixed path (not random) maybe it's possible to replace 3D graphics API and graphics card firmware with PTE code for hidden surface removal with transparency. Maybe by creating a custom lookup table for each slideshow generated with depth and transparency data including timecode which is then compressed embedded into slideshow. During playback it would be decompressed into memory and provide the data required for hidden surface removal with transparency. Lookup tables are not cpu intensive because the data has already been calculated. Then it would work on everything from XP to Windows 8. :)

  13. 4K and the future

    in Equipment & Software

    Posted

    My guess is that 4K UHDTV are currently for files already encoded in video format instead of display mirroring due to the GPU requirements. I am sure that will change as new GPUs that are smaller and faster with lower power requirements. The 8 MP screen resolution should make video slideshows look great. Of course professionals can buy hardware (current gen Mac Pro) that can easily drive a 4K monitor.

    I often watch PTE exe slideshows on my HDTV using my desktop PC over wireless (chromecast desktop). It's not bad but not 4K! Also tablets are really getting powerful. 64 bits, quad+ cores.

    10K photos a year? Amazing.

    Thanks,

  16. Video stabilization software good or bad?

    in Equipment & Software

    Hi Barry,

    Yes. I learned a lesson. It is important not to crop the subject too tight when you are not using a tripod in case you want to use video stabilization software.

    I wasted about an hour of time trying to do video stabilization in PTE by adding keyframes and selecting a fixed object on the screen near the border of the image (rotation near center is very hard to detect). The lower frequencies were easy to remove but the higher frequency vibration is very hard to remove by manual keyframe pan/rotate adjustments. It takes math and a computer to stabilize video.

    Hi Eric,

    About a year(?) ago DG tested 3D X axis perspective correction with good results. I think he was testing just images but it seems to work just as well with video. I did not find a How To for perspective correction. Probably a good idea if DG or Lin have time to add an example under 3D parameters or the How To section. I am a terrible writer.

  19. White Balance wizard

    in Suggestions for Next Versions

    Posted

    Currently Color Adjustment is limited to Original, Grayscale, Sepia, and Custom. It would be nice to have another option for White Balance. When selected a color picker would allow you to select an area on the image or video and set the reference white/gray neutral color. The color temperature would be adjusted based on the white area you selected.

    Thanks,

    Tom

  20. Object rotation wizard

    in Suggestions for Next Versions

    Posted

    Hi Lin,

    I'm sure you have used the Photoshop method for variable rotation using click and drag to create a reference horizon?

    I may be wrong but I think the click and drag between 2 distant points on the image (to establish either perfect horizontal or vertical) is faster and more accurate that manually using the rotate with grid option (which is awkward to fine control rotation even with keyboard). I find the "Photoshop" method intuitive for fine rotation down to .001 degree. The click and drag function already exists in Pixbuilder Studio so the source code could probably be added to PTE without much trouble.

    An even more advanced option would include 2 almost parallel lines and the software adjust the image so that they are exactly parallel (by auto adjusting the 3D X/Y axis).

    Thanks,

    Tom

    Like Photoshop and many other image editors it would be nice if we could click and drag a line between 2 points (vertical or horizontal) on image or video object to auto rotate image. I know some people think ALL image adjustments should be made outside of PTE but for beginners who just want to import some photos and create a slideshow a simple image rotate would help. The existing method of manual rotation using the alignment grid is not as accurate or fast as click and drag a straight line. Auto zoom to fill in rotated background would be nice too.

    Thanks,

    Tom

    Hi Mur,

    We plan to add geometric transformations of objects in future versions. This is not strict promise, but I also want to implement this feature.

    That would be fantastic if objects includes hidden surface removal. I hope it happens in a future version!

    Thanks,

    Tom

  25. One idea, more possibility

    in Suggestions for Next Versions

    It sounds to me what Peter is describing is a multiple track video editor (Non Linear Editor) like Premiere, Final Cut Pro, etc.

    This leads me to wonder when 4K video becomes the new normal how does Wnsoft market PTE? Does PTE morph into a video editor with image support? Most video editors can create video slideshows from images. If most display monitors are 4K or less what makes PTE stand out among the competition? The distribution format (binary instead of video)? The smaller file sizes (for non video slideshows)? Before Igor turns PTE into a video editor (I think) there must be a strategic objective.
