    Simulating Elliptical Motion

    Nice job Dave - Yes, it was JPD who first suggested this many years ago. One of my old tutorials (number 33) covers it also but the addition of the style will make it much easier for new users to understand and serve as a blueprint to build their own versions by substituting their own PNG objects for the Earth and Sun.. It works well for creating simulations of atomic motion (orbiting electrons) too. Below is a quick sample using essentially the same process with the additional use of a rotating Earth inside a circular mask, brightness control for the orbiting moon and more dramatic size change. The new features of PTE give the user lots of additional tools for making dynamic animations.

    HD Video As Good As EXE....

    Hi Dave, That would be a possible solution for viewing for those who are PTE users and especially perhaps after pte 10 when hardware encoding will greatly accelerate production of the MP4, but depending on the individual's hardware, the time necessary to both download the BIZ then create the mp4 might be the equivalence of the time necessary to download the huge MP4. In either case it might not be greatly different than downloading the zipped exe version but then that would negate the evaluation of the video as being perhaps equal to the exe. The other caveat is whether each person's hardware will create the MP4 in exactly the same qualitative way? For example, I found that trying to do this with my old standby Win XP system was impossible. Whether this is because of the known incompatibility between Win XP and PTE 9 or because of a system hardware deficit is still unknown. I haven't had problems with my Win XP and other projects or creating the EXE file, but creating this video simply couldn't be done with my old system. I did notice a couple other interesting anomalies which I will take up with Igor later. I found that using Jean-Cyprien's book style before his Rubik's Cube style in the same project resulted in loosing the background on the Rubick's Cube animation with it being replaced with a blank green screen and also adversely affecting the initial timing on the Rubick's Cube animation. It's still a big head scratch but not terribly important at this time when version 10 is on the horizon. Best regards, Lin

    HD Video As Good As EXE....

    Hi Igor, Yes the file size can be an issue for many of us - not so much for storage because storage is really inexpensive these days - but for sharing over the web when one doesn't have fast internet it's problematic. I'm always reminded of this because my neighboring town only 8 miles away has gigabit symmetrical internet available for the entire town and it's very reasonably priced. It's possible with that to download or upload an entire HD movie in ten seconds! Fiber optic lines will eventually make file size a non issue, but sadly smaller communities and the great distances between will mean that it will be many, many years before this type speed is commonly available in the USA. Perhaps is may be possible to create some sort of slight gaussian blur feature which will help with the banding. I know sometimes with photos I find that using a blur feature then subsequently using wavelet sharpening on the same image, banding can be made almost invisible. I'm not certain how amenable to this video might be? Having the much faster hardware video encoding with future version of PTE will be great!!! Best regards, Lin

    HD Video As Good As EXE....

    HI Frans, Thanks for testing! I can't be certain, but I suspect the reason is that not all players can handle 60 fps video or that not all players use the available resources (video card, RAM, etc.) in the same way. The fact that it plays correctly with one player and not with others indicates that there are sufficient resources with the hardware but that for whatever reason, not all player software uses it in the most expeditious way. Best regards, Lin

    HD Video As Good As EXE....

    Hi Denis - Thanks for checking it out! What I mean by files size doubled is that since there are double the number of frames, the portion of video which consists of images is doubled in size. The rest of the overhead is not greatly affected, but since the images themselves must be stored inside the video, that part with all other factors such as image dimensions, etc., being consistent by doubling the number if images the storage requirement is doubled. I haven't tested this particular file at 30 fps but it might not be a bad idea for comparison. I didn't load it to YouTube or Vimeo because I'm not certain what they do in terms of file manipulation and because my own internet connect is quite mediocre, I never know what others with fast internet are seeing. It took over three hours to upload the video to my server - on a good day maybe I can get .75 - .90 mbps upload speed so I rarely upload large videos. It's good to know that others are also getting good quality with this one. People only 10 miles from me in an adjacent town all get 1 gigabyte symetrical but where I am, the fasted I can get is DSL... Best regards, Lin

    HD Video As Good As EXE....

    LOL - yep flag and wind physics have to take a backseat to the possible... Actually, the number of frames per second doesn't affect the speed of the video, only the smoothness. The exe files we create average 60 fps and 30 fps video can't render animations as smoothly. Using a higher frame rate in the same period of time just gives additional increments which smooth up the motion. Typical movies were shot at 24 fps and to get smooth motion, they used special tricks such as blurring the leading edge of an object in motion. With higher frame rates the apparent motion is much smoother, but the size of the video file is doubled. Think of it like this - you have a deck of cards on which there are drawings of a subject in motion. Let's say there were 24 drawings each representing part of a sequence of someone taking two steps. You flip all 24 of them in one second and observe. You see the subject take two steps, but the distance traveled with each card is much greater than if you had sixty cards with each card representing a shorter distance moved. If you flip all 60 in the same one second, the subject doesn't move any further than the two steps, but the motion is less jerky because each card represents a smaller amount of travel. So 60 frames per second covering the same capture of motion is much smoother than 30 frames per second or 24 frames per second. The more frames each representing a smaller amount of travel in terms of motion in the same time frame (one second) the smoother the appearance of motion. Thanks for checking it for me! Best regards, Lin
  7. This was the first HD Video I've made (made with the latest version of PTE) which I believe equals the EXE file in every way. It's a remake of my "What Can I Do" demo of PTE with some added material. It was done at full HD 60 fps and it's big - 1.274 gigabytes zipped mp4 for anyone interested. If you have the bandwidth and want to see it I would appreciated comments about the video quality. I played it on my 30 inch 2560 x 1600 display with Win 8.1 on a high performance high RAM system and it looks excellent. http://www.lin-evans.org/pte/whatcanido2018.zip Best regards, Lin

    Reminder About PTE Facebook Group

    Gary, the way FB works is that you have various "privacy" settings. If you don't see video shows on other's FB sites, it's probably because they have their privacy set so that only their friends can see them. Facebook is a broad use media platform and not everyone posts their videos there. There are a number of shows on the PTE Users Group which are not mine, but I try to put up something every month or so and because of that many are mine. The FB PTE User Group has been online for a number of years. I took it from Private to Public in May of 2015. The idea of the group is for discussion, demonstrations of new techniques, what people are doing with PTE, answering questions, etc., so videos themselves are only a part of the intent of having a group. Maybe many of the users do not create videos or are only interested in finding out about the program. The larger the group becomes, the more people will know about PicturesToExe and that's the primary purpose of having a group. I suggest that whenever someone joins the group that they sign up all their FB friends whether or not they are PTE users. They have the option of opting out if they don't want to belong to the group. Unfortunately, not too many of our users have done that but the more people we can convince to add friends, the more exposure is possible. It's not necessary to put all one's shows on the group - just ones which you particularly like or have some special feature, etc. It's not meant to take the place of Slideshow Club, only to spread the word about PicturesToExe. Hopefully if more people add their friends to the group, there will be greater interest, greater purchases which will allow more development and refinement which will benefit all users. Best regards, Lin

    Reminder About PTE Facebook Group

    Hi Gary, The "group" has it's own provisions for posting shows. It has no relationship to the member's own FB sites. If you want to post a show on the group site just do it like you would on your own site. When you upload a show to the group FB page it will be shortly approved then appear along with any associated text. Best regards, Lin
  10. If you are a Facebook user, please come visit and join the PTE Facebook Group Folks - There you can post shows, images, etc., and discuss PicturesToExe.... The link is below: https://www.facebook.com/groups/picturestoexefans/ Lin

    Save hot key in O&A window

    Hi Geoff, I don't believe it works from O&A but it doesn't work with my earlier versions either (Win 8.1 and Win XP) so don't know if it ever actually did. I haven't tried with all previous version of 9 but it doesn't work with 9.0.16 or 9.0.17 for me... Best regards, Lin

    Hi Jose, Sadly, I have no other suggestions. I don't make large video files so this is an area outside my experience. Perhaps Igor my have a suggestion... Best regards, Lin
  13. Lin Evans


    Just a thought Jose. Could you try creating the PTE files as AVI rather than MP4 then try to join? This would mean a different codec would be used. Not having ever tried this I can't be certain but the error message references a codec issue and creating as an AVI uses a different codec. Perhaps after joining the show can be converted to MP4? Best regards, Lin

    pte 8 Using videos for moblie devices

    Sorry to be so late answering your question. The show needs to be in some location where it can be downloaded by the person who it is shared with. You can put it on a private website or in the Cloud (if you have Cloud storage), on YouTube, Vimeo, etc., or on a media sharing site such as MediaFire. The show you share should be in a video format. The person who then wants to see your show and upload it into their phone needs an app which allows this or they need to use the internet. You could also email them the show if it's small enough and they can save it from the email. Since there are multiple types of smartphones - I can't speak for all them but the user can contact their phone service company for specific directions for their own phones. Best regards, Lin

    Reminder About STYLES For New PTE Users

    It depends on whether you are referencing the camera or the image. Since PTE is an image/slide program the reference by the various author's of these styles are the image and not the camera. So if the camera moves from the right to the left the image appears to move from left to right, etc. The actual image itself is a static item zoomed in and the view as seen by the observer moves either to the left, right, up or down or any simultaneous combination of left/up/down or right/up/down. A camera pan would be relevant in a video were an actual pan done, but not in a still image. The demonstration simply gives the name of the style given by the author then shows what it does.
