• Improved the Trim and Adjust Speed window (for a video object):
  • Improved interface: window size is now remembered between sessions;
  • Pause key can now be used to play/resume video playback;

It doesn't seem to be working as it should at the moment.
You need to Tick the Box 'Speed Keyframes' to be able to add them. This then disables the Speed Adjustment box.

In previous Beta's (7 & 😎 I could add the keyframes at the Start to slow down, or Hold, the video.

But as the Green bar does not change in duration to match the new Video time, it was difficult to add the Keyframes at the end in the right place once the Speed had been adjusted.

Now in Beta 9 I am really struggling to get the Keyframes at the Start. I can add them, but when moving one to a Zero Speed it seems to move the Start Position of the Video.

Jill, I agree, something wrong with changing/adding first keyframe and scale of the timeline. 
Please wait, we'll improve the code.

I guess I should explain what I am trying to do and then see if what I want can even be done within PTEAV.  Google Earth has a feature to create a "tour" where you enter points and then record the tour.  Then you can export the tour as a video file.  My "tour" is just 2 points with a start city (Los Angeles) and an ending city (Auckland).  I want to use this as my first "slide" in another one of my travelogue shows I am working on.  I when playing the Google Earth generated movie the speed throughout is fairly high.   I want it to linger longer on the starting and ending cities but be normal speed or greater for the "flying over the ocean" portion.  So far the only place where I have been able to accomplish this is within the Trim and Adjust Speed sub-window of O&A.  But the changes don't "stick".  So am I trying to accomplish something that cannot be done in PTEAV?

Please try a simple idea - create a smooth video slowdown, a pause (1 s), and then a smooth resume of playback.
I showed how to do this in the screenshot below.

First, make sure you are using the new version - Beta 9.

1. Tick "Speed keypoints" option.
2. Add 4 keypoints, as shown on the screenshot.
3  Click the OK button to save the result.

Check the preview in the Objects and animation editor and the Mini player in the main window.

Trim works OK.

However it does not alter the duration of the slide to suit the new video time.

Cannot add Keypoints but changing speed is possible via the data input boxes.

Dave,

Ealier, slide duration never changed automatically when the duration of a video object changed. Because a slide may contain other objects with their own durations.
The only case when a slide duration automatically updates is when replacing a video object file name throught the Open file window, if its duration matched the slide duration.

You need to tick an option "Speed keyframes" before adding any speed keypoints in the timeline.

[Support Apple .HEIC file format [DONE]]

I agree it would be a nice feature. Currently on a Mac (11.0.3) it's possible to create a show with HEIC files and publish as a Windows Safe Executable for PC. When the Windows PC tries to run the show it will show an error message on a HEIC file. Ideally Windows version of PTE would support HEIC or the Mac would provide a compatibility warning during publish.

Thank you very much for this information and for your feedback on Diapositif. I understand the difficulty encountered for the integration of the HEIC format in the Windows version.

Hi,

I apologize it took so long! In the new version 12.0 Beta 9, we've added full support for HEIC images to PTE AV Studio.

Please try it out and let me know how it works.

[HEIC / HEVC support]

We published V12 Beta 9 with HEIC image support for Windows today. Now HEIC supported on a PC and Mac.

[When you save a project, it saves unused material]

On 3/22/2026 at 12:21 PM, SoCu said:

Hi, I have a project with two slides. I tried adding a transition, and then added another one at the end.

But when I save the project or export it, I see that the file is much larger, and I noticed it creates a folder with the video files containing the transition I tested.

Maybe I’m doing something wrong, but this also happens in version 11.

When the project is saved, shouldn’t it only save the footage actually used in the project?

I think that we solved this in the new Beta 9 today.

Still having a problem with the Trim and Adjust Speed option in Objects and Animation for a single video clip.  I used Google Earth to record a "movie" that shows flight path from A to B.  I open the clip in PTEAV  and I wanted to start the beginning a bit later and then alter the speed during the rest of the clip.  This is what it looks like in the Trim and Adjust Speed window and it plays fine in that window. 

Please try new Beta 9 released today.

Hi, the app freezes when you least expect it; the slide disappears, and nothing is displayed.
I've also noticed that the *.lock file remains at 0 KB. 
I close the app, but I can't delete that file.
I check the task manager, and PTE is still running, even though I've closed it.

These crashes happen almost constantly

Hi, try new Beta 9.

[PTE AV Studio 12 Beta 10]

Beta 9 is available

See the download links above.

• Added HEIC image support for Windows - the format used by iPhone for storing photos by default. Now available on both Windows and macOS.
• Added AVIF image support for Windows and macOS.
• AV1 video export is now 18% faster with slightly better quality and smaller file size.
• AV1 video playback is now hardware accelerated on Mac with Apple M3/M4/M5 chips, significantly reducing CPU load.
• Improved the Trim and Adjust speed window (for a video object).
• Fixed an issue with clearing unused resources of a project (slide style or custom transition).
• Fixed an issue where the program froze when a project contained a missing video file.

[JPG XL Support?]

On 3/17/2026 at 11:17 PM, Almark said:

Will jpg xl be supposed in this version?

Mark, did you mean standard JPEG-XL images as .jxl files, or JPEG-XL from iPhone?

JPEG-XL from iPhone is a DNG file containing both RAW data and an embedded JPEG-XL image.

[HEIC / HEVC support]

Hi,

I'm testing HEIC images support for a PC (Windows) in PTE AV Studio right now. If all is OK, we'll add it for V12 soon.

It was not easy to support this tricky format! Interesting fact, a typical HEIC image file from your iPhone contains a grid of 48 small video fragments (4 x 8 tiles - 512 x 512 pixels short video clips which contain 1 frame, still picture) + meta data (rotation, color profile, thumbnail picture). 

I discoverd that even latest IrfanView cannot display correctly colors in HEIC images, colors are distorted slightly.

[Video Speed Adjustments]

Hi,

Please wait for Beta 9. We'll publish it within 2 days. We've added many improvements to this editor.

Also we updated video decoders/encoders in Beta 9.

[Video Speed Adjustments]

I thought you needed a simple way to merge several video files.
Then PTE AV Studio would probably be suitable for adding transitions between videos.

... I had 4 or 5 clips that I ended up merging into a single clip using Movavi. 

Just an idea. Try PTE Video Optimiser. It can combine several video files into one.

[viewing the slidelist]

Hi,

If I understand correctly, it is not a V12 bug, and the same applies to all versions of PTE AV Studio.
Thumbnails in the Slide List (Timeline) display the slide content at the end of the slide transition.
We could potentially redesign this, but there are several options for how it could be implemented. Another problem is that adapting a setting for one project may not be optimal for another.

I will glad to hear suggestions of members.

When I go to check results, not all of the sound is missing on the last few slides of my project. Then the last few slides are totally gone and the beginning starts again before ending after a few slides that are NOT in the order they should be. 

Hi,

Can you share a copy of your project with us? We'll check the cause of this issue to help you.
Use the "Create a backup in a ZIP" command from the main menu > File menu to create a full copy of the project with all linked files.

P.S. Jill, thanks for your replies!

[Question on "Work in Progress" section]

Hi,

I suggest to move all the messages of this section (Work in Progress) into the main section - General Discussion.

[Window buttons: Choose a color]

You need to use display Scale option, not Text size. I recommend to set Text size to 100% (default value) and then adjust display Scale to 125%

Custom scaling where you probably set custom Text size instead of display Scale:

 

[Video Speed Adjustments]

Jill, 

The green timeline (with key points) always shows the original time. Including vertical red time cursor.

Mini player placed above (and its time slider) shows modified resulting time.

Please wait a little, I've noticed several issues with time calculations. We'll fix these mistakes in Beta 9. I suggest to try again this editor in future Beta 9.

In fact the keypoints at the end of the video don't seem to be working at all.

It doesn't matter where I position it, the video isn't slowing down at the end.
The starting points work great, but the end doesn't

Jill, thanks, we'll fix it in Beta 9 soon.

[Window buttons: Choose a color]

Hi,

PTE AV Studio fully supports HiDPI and Windows display scaling. We recommend to use Display settings - Scale (e.g. 125%, 150%) to make everything larger - NOT adjusting the text size separately.

Could you check what your current Scale and Text size settings are in Windows Display Settings?

Personally I use scale at 140% for my Dell monitor and the Color window looks rightly:
