Please create a simple project with this file. Use Create backup in a ZIP command from the main menu > File menu. And upload this ZIP archive for me. We'll check it again.

Thanks for the audio file (01 Babysitter-Boogie.m4a). Regrettably I couldn't reproduce that problem. I started a new simple project - 5 images and this audio file. No problem with MP4 video output (Windows 10).

No worries.

Many thanks! I've reproduced this issue. We'll try to fix it.

Denis, I understood now. Try a new Beta (Build 5): https://files.wnsoft.com/test/pteavstudio-setup.exe

Try to copy one project from these transfered templates into a new folder and open this project as usual project (not as a template). I meant copy within Mac to Mac. Also try to pack to a ZIP archive a project and then unpack and open in PTE. P.S. I forgot to ask - did you open that project from a local Mac drive, or from network storage?

Does this problem (delay) occur in other projects or in a certain project only? Try to create a new simple test project with 10 images and one MP3 audio file. Do you observe the same delay? Also try to restart macOS, if the problem (delay) occurs in all projects.

Hi Denis, This problem might occur with Windows XP and Vista. And probably earlier builds of Windows 7. And only with buit-in ZIP unpacker. There is no problem with later Windows 7 updates, also Windows 8, 10 and 11, and Mac can unpack ZIP archives with non-Latin symbols. Also external ZIP unpackers don't have this problem many years. So we removed that warning since version 10.0.

Hi, I'm glad that you solved this problem! Can you send us the original audio file which caused that problem? We'll check it and probably a protection for this case will be added. Upload to iCloud, Google Drive, or WeTransfer, and then send me a download link in a personal message.

Hi, Please send me this .pteav file via WeTransfer or Google Drive, or iCloud.

Hi, I understand that this point is important for you. I can't promiss firmly, probably we will able to improve a transition to a new launched show in future version. You wrote about this issue after 2 years since a release of version 10.0 where this behaviour appeared first time. Did you notice it first time? I don't remember other reports on this subject earlier.

Hi Ken, A project may has only blank slides (with text objects and rectangles) without any images. It should work fine. And I frequently created such projects for testing purposes. If you think that you discovered a problem, please send us a sample project for testing.

Hi, PTE AV Studio code fully unloads current show and then loads a new show on Run Slideshow command. There is a short gap and you can see a quick black flash. It didn't appear in the old version 9.0 and earlier - because a screen buffer were not updated and it masked this gap. To fix this flash in current version it will require a serious change in the 3D engine (time and then testing). Honestly, we would prefer not to add this change for current version to avoid new unexpected problems.

Hi, Do you create an executable show for PC/Mac, or MP4 video? This feature doesn't work in a video file MP4/AVI.

I see these problems. Thanks.

Hi Daniel, We didn't change anything in the code which could cause this strange problem. Try to uninstall PTE AV Studio 10.5. Restart Windows. Then reinstall the latest version 10.5.6 Beta again.

Hi, The most likely, the problem occurs with a certain audio file. Start a new test project and add the audio file which cause this problem in MP4 video output. If the problem is confirmed, send us this audio file via WeTransfer.com or Google Drive in a message through https://www.wnsoft.com/en/support/ (add a note: for Igor) or as a personal message on this forum. Or you can send us the entire project in a ZIP archive. Use a command - Create backup in a ZIP from the main menu > File menu. P.S. Please add English translations for your replies for other members.

Thanks, we'll check on Monday.

Gary, OK.

A funny bug. Mouse and memory leak.

Hi, PTE AV Studio 10.5.6 Beta is available. What's New: Added support for video files in .ts format. Fixed problem with author’s commentary after renaming of a slide style. Fixed rare problem with a lag (0.5 s) with audio playback on some computers (Windows only). This issue appeared since version 10.5.0. Fixed problem with crashing on wrong JPEG files (Mac only). Fixed problem with reduced loudness for mono audio clips on 3 dB. This issue appeared since version 10.5.0. Download: For Windows: https://files.wnsoft.com/test/pteavstudio-setup.exe For Mac: https://files.wnsoft.com/test/PTE-AV-Studio.dmg PTE AV Player for Mac: https://files.wnsoft.com/test/PTE-AV-Player.dmg

Fine. Please check other projects other audio clips to make sure that everything works correctly. I also discovered that some videos from smartphones (iPhone) are recorded with mono sound. So this change will affect these video clips, too.

Daniel, Audio files (and also video clips) of a project are opened and partially loaded by PTE AV Studio. They are ready for instant playback at any moment. Unlike images, PTE AV Studio doesn't load entire file, because a media file can be very large. It's not good idea to replace them outside PTE AV Studio when a project is opened, it will lead to an unexpected behaviour of the opened program. You need to use Replace Audio File command (as you wrote), or close PTE AV Studio and then replace files in Explorer or in other editors. PTE AV Studio loads audio/video files with a soft "read" request and doesn't prohibit writing/replacing of a file for other apps for better compatibility.

Done: https://files.wnsoft.com/test/pteavstudio-setup.exe

Try a new version 10.5.6 Beta: https://files.wnsoft.com/test/pteavstudio-setup.exe Note, that you need to manually clear the cache of waveforms, or rename a WAV file to update old waveforms.
