Hi, try new Beta 9.

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.

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.

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.

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.

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.

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

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.

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!

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

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:

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.

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

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:

Hi Jill, Please check the About window. Do you use the newest Beta 8? In Beta 7 and 8 we added many changes and improvements into video speed editor. I'll write a mini tutorial for this editor soon.

I need a project to check it with V12 Beta.

Hi, The most likely that some file in a project, most likely a video, is causing the freeze. Try to reproduce this problem in a simple test project. If you can reproduce the issue from a scratch with a simple project (from opening of a project, to a sequence of short actions until the freeze), please send me the entire project (with linked files) in a ZIP file and instructions on how to recreate it. The remaining .lock file is an indicator that the project is still open in PTE AV Studio. This is simply a result of the freeze.

PTE Video Optimizer can reverse video and then export the result. Check also the preview in realtime - it may freeze sometimes, because it's a difficult task to decode a reversed video (on the fly). P.S. Exported reversed video will play smooth.

Sorry, this isn't possible in real time. We cannot include this for PTE AV Studio. You can see how reverse video works in PTE Video Optimiser. For a smooth playback you need a fast PC.

We'll fix it in future Beta 9.

I think that I've understood what happened. It appears that the versions (revisions) of this transition are different (in the project and in the global storage). You previously applied this transition to slides. Then you modified the transition in the global storage being in another project (changed something). Usually, when a project uses a transition, it syncs automatically, but this didn't happen in your case because the transition wasn't used but hadn't yet been deleted from the project. We'll try to fix this. Simple solution: 1. Temporarily apply this transition to one of the slides. 2. Click OK and close the project. 3. Open the project (PTE). 4. Untick the transition. Click OK and close the project (PTE). Now unused resources will be deleted automatically from the project folder.

Beta 8 is available See the download links above. Improved the Trim and Adjust speed window (for a video object). Also the original duration is now displayed correctly. Quick Search accent-insensitive matching has been improved with broader language and character support. Improved installer on Windows: fonts now render larger and are easier to read at 125%+ display scaling (HiDPI support), and the installer now respects the system Dark Mode theme. Added a Japanese translation.

I downloaded and checked your project Proyecto 2_Mar22-2026_9-30-44.zip (62 MB). This project includes one heavy custom transition (10 variants, 62 MB, 20 video files). It's included as Embedded transition (local project storage). It means that it's included in the project (not in the global storage). For this reason, the program doesn't clean up its resources, even if no slide uses it. This is because the transition is stored in a single, unique instance - in the project's resources. If the transition is in the program's global storage, the program (PTE AV Studio) automatically cleans up the project's resources as soon as all slides stop using it (when the project or PTE AV Studio is closed). To resolve this particular case, simply remove the transition in the list of transitions in Project Options / Slide Options and close the project. Be careful - re-check that you have a copy of this transition before deleting it. If you didn't specifically create this transition in the project's local project storage, this situation could have occurred for the following reason: 1. You created or imported a new transition into the program's global storage. 2. You used this transition in a project. 3. Then you shared a ZIP copy of the project with another user (or moved the project to a second PC). 4. PTE AV Studio always saves a local copy of the transition in the project, so you can correctly open this project on another computer where the transition isn't yet in the global storage and it won't be automatically added there. 5. Thus, the transition becomes a local transition (embedded transition). If you now stop using this transition, resource cleanup will not occur automatically.

Hi, We're planning a major improvement to a text object before the final release of version 12.0. I just want to make sure the new code works as intended before announcing it. Regarding the issue of keeping consistent text size between slides. I understand this task. But how can we implement this, if the text size depends on where the text object is added - on a slide or as a child object? Years ago we've added one solution (which, of course, isn't suitable for all cases) - a text comment. The text object has a special mode - text comment. And its size can be controlled through the Project Options (for all slides or for new slides) in the Pro version of PTE AV Studio.

Re-open this project (or restart PTE AV Studio), and the program will remove unused resources associated with this project. This works this way, because user can undo changes (Ctrl+Z) and return some transition with video resources to the project. Therefore, clearing unused resources always occurs when closing the program or closing the project (re-opening the project).
