Hi, thanks for the confirmation. I'm glad!

Hi, I moved your post to this topic. Glad that one problem with the hardware encoder is solved now. Regarding the second issue with iPhone videos: Please tell me in more details: So you have original iPhone's video (MOV file) and it plays smooth in QuickTime player on your Macbook? Then you start a new project in PTE AV Studio 11.0.15 Build 3 (the latest version, it's important), add this one video file. Do you click the Preview button and see this issue (not smooth playback) in a full screen preview? Or you create a MP4 video from your project in PTE AV Studio and then play the created MP4 video file in QuickTime and see not smooth playback? It's important point to understand where exactly the problem occurs. I share with you a test video recording from my old iPhone (1920 x 1080, 60p), a train in mountains: https://drive.google.com/file/d/1z5tFzMSBiuVOxqoBqtoD_DOsaTY73H-J/view?usp=sharing This video play smooth in PTE AV Studio (a full screen preview) and smooth playback when I create a MP4 video (1080p 60) from the project and then play the created video file in QuickTime or VLC player. I tested on Macbook Air 13 with M3 chip. macOS 15.1.1 You can share your video sample. We'll check it. Note, that playback of 4K video (added a project) in a live preview of PTE AV Studio (full screen preview) may be not enough smooth. Or if you add several videos, because during a transition effect two or more mixed videos appear on the screen at the same time. However once you create a final video at 1080p or 4K, the created video file should play smooth in QuickTime, VLC or Apple TV. Please also share a screenshot of the video export window in PTE AV Studio to see what settings you have chosen.

Hi, Please download again the updated v11.0.15 Build 3. It will fix the issue with dropped frames when using hardware encoder option on Mac with Apple Silicon running macOS 15:

Hi, We published the updated v11.0.15 Beta. It finally fixes an issue with dropped frames (choppy playback) in created MP4 videos with hardware acceleration on Mac with Apple Silicon running macOS 15. The About window shows v11.0.15 Build 3.

We found a solution for the hardware encoder on Mac running macOS 15 Sequoia. I hope to build the updated version tomorrow or on Monday.

Tom, I've thought about this topic. The Logo is one of several possible parameters which can customized for every video clip individually: color adjustments, size, background, etc. If the user merges several video files into one and wants to set some common parameters (one or several), the simplest way is to select these video clips in the Slide List (with the mouse cursor) and apply group editing of the desired setting. For example, choosing the Logo. Then the Logo will become common for this group of video clips.

Hi Tom, Thanks, we'll do this.

Hi, Beta 4 is available. For Windows: https://files.wnsoft.com/ptevideooptimiser/ptevideooptimiser-setup.exe For Mac: https://files.wnsoft.com/ptevideooptimiser/PTE-Video-Optimiser.dmg I recommend to uninstall previous Beta version and then install the new Beta 4. Activate it with a free public license key for the Beta versions: C1UBM-LMFBG-JGJME-2UJ89-MK7J4 Changes in Beta 4: Encoding AV1 video on Mac with Apple Silicon is much faster. Fixed an issue with an error message on replacing the existing file. Fixed an issue with the Merge All Files function on Mac. Improved translations: Dutch, French and German.

This issue should be solved in Beta 4.

Hi Denis, We updated the translation for Brightness parameter in Beta 4 today.

Do you add iPhone's video to a project, create a new MP4 video (Hardware Accelleration is unticked), and play the created video on Apple TV, right? It should play smooth, because PTE's video encoder works independently (autonomously) from any changes in macOS. If the created video play smooth in QuickTime player on your Mac, it also should play smooth on your Apple TV. Just in case, I'll clarify that you need to choose "60p" option in video output for the better smoothness, not 25p or 30p. 2. Also I recommend open the Sample Project (from the main menu > Help menu > Open Sample Project), produce a MP4 video. HW option is unticked. Then then compare smoothness - on your PC and then Apple TV.

I discovered a similar issue with another app Handbrake on Mac: It seems that Apple has changed something in the work of hardware encoder in macOS 15.1. I see that Handbrake developers found a solution. We'll learn their code. UPD. I think that unticked the Hardware acceleration option should completely solve this issue as a workaround.

Hi, I merged both topics into this one. I confirm this issue with V11 when using "Hardware acceleration" option, even with the latest Beta version. Please give us some time to explore this issue.

Today we improved a work of PTE AV Studio 11 on Macbook's screen with the notch. The updated Beta is uploaded. The About window shows v11.0.15 Build 2. It should be the final stable version.

Can you check again - the About window in PTE AV Studio should display v11.0.15 Build 1 - this new Beta version. Just to make sure that you use the necessary version. Please open the Sample Project (from the main menu > Help > Open Sample Project). Create a MP4 video and check on your Apple TV. Can you also compare 1080p and 4K videos.
