Hi Igor, You are right about the variable frame rate of my iPhone 13 Pro video. I did some more experiments and used handbrake to convert the video into a constant framerate video before importing it in PTE. Then the problem is solved and the published video is fine. This is a lot of work however, because I have many hundreds of videos... Could PTE not implement the same algorithm as handbrake to convert VFR videos to CFR before publishing ?

Yes. Yes. Yes. Yes and also on AppleTV. If I import your video in my project, it plays fine (both in preview and when published). So there seems to be a difference in video formats between your iPhone video and mine. Here is a link to a shared folder with my files: https://drive.google.com/drive/folders/12_1Gy-eO--fI6P0wgv8WCIAsbLIgJR1h?usp=drive_link It contains my iPhone video (IMG_3473_trim2.mov), the pte project file, the published mp4 file and a screenshot of the publish settings. I hope this helps you to find the cause of these problems.

I tried the new build 3 and can confirm that the hardware acceleration is now working again and the choppiness of panning across still photos is now gone, but the problem with the imported iPhone videos is not solved. I think this problem has another cause. The choppiness of the videos is different from the choppiness that that was on the still pictures. The still pictures had a constant jittering whereas the videos have a sort of small pause about every second when published at 30 fps and about twice every second when published at 60 fps. This can be seen very clearly both on the MacBook and the AppleTV and both for 1080p and 4k videos. The original iPhone videos play back perfectly on both the MacBook and the AppleTV. Edit: I should have posted in this topic: https://www.pteavstudio.com/forums/topic/46348-sequoia-problem-video-not-smooth/

I cannot confirm this; unticking Hardware acceleration does not fix my problem with stuttering iPhone video's.

I have similar problems, see this topic https://www.pteavstudio.com/forums/topic/46442-stuttering-video-playback-problem/ I just installed v11.0.15 (Apple Silicon) Build 2 and did some publish tests. The published show contains a short iPhone video and some cropped pans over a hires still image. test 1: 1920 x 1080, 60fps, hardware acceleration enabled test 2: 1920 x 1080, 60fps, hardware acceleration disabled test 3: 3840 x 2160, 60fps, hardware acceleration enabled test 4: 3840 x 2160, 60fps, hardware acceleration disabled I watched the results both on my MacBook Pro (Quick Time player) and on Apple TV (infuse media player) On test 1 and test 3 (hardware acceleration enabled) the results are bad: the iPhone video is very jerky and also the pans are not smooth but have a small (but irritating) stuttering. On test 2 and test 4 (hardware acceleration disabled the results are much better but not ok yet. The iPhone video is still jerky but the pans are perfectly smooth. The 4k version is a bit better than the 1080p version. BTW, I am on MacOS Sequoia 15.1.1 (24B91)

I just noticed the other topic concerning this problem: https://www.pteavstudio.com/forums/topic/46348-sequoia-problem-video-not-smooth/ I will also try the new beta build and post my results there.

I have a problem creating stutter-free video presentations using PTE AV Studio. This is my situation: I am using PTE on my MacBook M1 Pro to create a video from various media sources such as iPhone photos (HEIC) and video clips (1080p 25 and 30fps) and “real camera” (Sony A7III) footage, also photos and video clips. My goal is to create a HD or 4k video that can be played on my LG tv, using an Apple TV media player. The problem is that when I create a presentation using PTE’s publish HD and 4K video, the result is a mp4 file that has stuttering issues. The stuttering is most severe on some iPhone videos the are included in the presentation, but is also visible on hires still photos from the Sony camera when panning a cropped portion of the photo. I have tried lots of combinations of resolutions and frame rate settings, but the stuttering will not go away. It does not matter if I play the presentation on the Apple TV, a Windows PC (using VLC) or the MacBook (QuickTime player). If I use the “Convert/Trim video clip” command to process the videos before importing them, the stuttering gets even worse. I get the best results when publishing as “Video for Mobile Devices”. Then the stuttering is still visible on the included iPhone videos, but the panned hires photos are perfectly smooth with no stuttering at all. Also when previewing the presentation inside PTE or publishing as “Show for Mac” and using the PTE AV player for playback the result is perfect, even the included video’s do not stutter at all. However, the PTE AV player is not available for Apple TV. Are these stuttering issues a result of my setup or could there be a problem inside PTE’s publish code?

Hi Igor, I tried build 4 and can confirm that the error has been fixed.

Without Reversed Order I have not been able to reproduce the problem.

I tried with a folder containing a small number of files, see attached screenshot "filenames.png". At first I had the File List Sort Order set to "Exif Date", trimmed a file and had no problem. Then I switched the File List Sort Order to "Name" and "Reverse order" and trimmed the same file again. After trimming, PTE came back with an "Image load error", see attached screenshot "error.png" Also, the file list was corrupted again, see attached screenshot "corrupted list.png"

If I select a video file from the file list and do a "Convert/trim video clip", I would expect that after converting/trimming the converted file should show up in the file list next to the original file. However, when the conversion is ready, the file list shows up again, but is corrupted. Some thumbnails do not match with the file names anymore, see attached screenshot. You can see that the video file gets the name of a still image (A7_04287.png). After switching to another folder and then switching back, the file list is ok again.

I checked with version 10.5 and it also crashes. You don't need to add an image to the timeline, just selecting an image from the file list in fullscreen mode and double clicking it in the preview window will cause PTE to crash. I'm using the touchpad of the MacBook.

After some more testing I think the crashing is also caused by PTE's inability to handle fullscreen mode. I can now easily reproduce a crash (using latest PTE V11 RC): Create new project in partial screen mode, add an image to the thumbnail timeline (any image will do), enter fullscreen mode, double click the image => crash crashreport.txt

I tried this new version and I can confirm that the .HEIC image now renders correctly. Thanks! I have also downloaded version 10.5 and this version works fine on my system. I did not have a single crash. With PTE V11 RC3 (4?) I have noticed one more problem: if I run PTE in fullscreen mode, I cannot drag items anymore. I cannot drag images into the timeline or move images along the timeline. As soon as I start to drag, the PTE window completely disappears from the screen and I am left with my draggable item over a clean desktop. If I switch to partial screen mode, dragging is working fine.

I am experiencing lots of problems with the Apple silicon version of PTE version 11 RC3. Crashes happen at various moments: when dragging an image into the timeline, when double-clicking an image, when clicking the preview button. These crashes do not happen always; I have not been able to consequently reproduce a crash. However, they happen very often, like 20 times in half an hour. Sometimes I can then restart PTE without a problem, but sometimes I must first use the "Force quit" option to kill a crashed PTE instance. I am using PTE on a MacBook M1 Pro, 16 GB RAM, OS: Ventura 13.1 Apart from these crashes, there are some other problems with this version: Some .HEIC images do not display correctly in PTE (they are ok when viewed with other apps). It looks as if a colour channel is missing when viewed inside PTE. Most .HEIC images render ok however; it's about one in ten that have a problem. I have attached an image that will not display correctly in PTE. .MTS videos can only be played from the very beginning, if I move the cursor along the timeline, the video starts to stutter and will not sync until I place the cursor at the start again. Is there anything that I can do to help to resolve these problems? Edit: I added a crash report Crash happened when clicking Preview button in Objects and animations screen.
