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.

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.

Hi Daniel, When you call Save As command for a project, a folder with resources should be saved under a new name automatically. If it doesn't happen, please send me the original project in a ZIP (before renaming). I'll check it. Note, that if you rename a .pte project file manually in Windows Explorer, you also should manually rename resources folder.

Daniel, We'll add support for .ts video files in the next update. Earlier PTE didn't support that file format.

We fixed this issue today. I'll publish a new Beta tomorrow.

Thanks, Jean-Cyprien, Philippe, for the confirmation. I'm very glad! Our team fixed this problem. Please check several projects to make sure tha audio clips play correctly in different situations: playback, pause, rewinding and synchronization.

Denis, Improved in v10.5.6 Beta: https://files.wnsoft.com/test/pteavstudio-setup.exe

Hi Jean-Charles, Please try a new version 10.5.6 Beta: https://files.wnsoft.com/test/pteavstudio-setup.exe It should fix this problem with sound lag.

Denis, We'll increase width of this button in the next version 11.0.

Hi Denis, Sorry for the delay. Can you tell in more details? Do you mean the Objects and animation editor, or the Project Options > Defaults tab?

Hi, Does this problem with missing sound occurs with any projects, or with a certain project? Try with a new simple project - 5-10 images and one MP3 music. Encode a MP4 video.

Hi Judy, For PC NVIDIA graphics is the best choice for PTE AV Studio. It's fast and you can use hardware acceleration for video encoding with good quality. NVIDIA Geforce 1060 still excellent video card for PTE AV Studio 10.5 for any tasks. So you can buy any modern NVIDIA graphics from 1060 series and higher (1070, 1650, 1660, 2060, 3060, etc). For laptops I especially recommend NVIDIA dedicated graphics. For Mac New Macs with Apple M1 chip is excellent choice. Apple M1 Pro or M1 Max are ideal choice.

That's fine

We fixed this issue. Try a new Beta version: https://files.wnsoft.com/test/pteavstudio-setup.exe

We discovered that a new audio channel is created in time and playback is started, but first audio buffer arrives with a 500 ms delay. Seems to be a bug in audio drivers (maybe Realtek). On our laptop this issue occurs only when I disable Stereo mixer for a microphone in Windows 10 control panel. Previous PTE versions created a silent audio channel to synchronize the timer with the audio device on PTE launch. In version 10.5 it occurs later on first click of the play button. We found a solution to avoid this delay. I'll publish a new Beta version when it's ready.

Thanks for your responses! I finally reproduced this issue. It occurs with a certain settings of audio mixer in Windows 10. We'll explore why it affects to PTE 10.5.

Thanks, I confirm this issue. We'll fix it soon.

Hi Jean-Cyprien, Thanks for testing. I'll wait for your reply regarding Question 2. We need to think about this issue. Do you observe the same problem on another computer?

Thanks for your opinions. We'll try to make it as in earlier versions. P.S. I moved my reply to this topic, wrongly posted in another thread.

Jean-Cyprien, Thanks, Interesting problem. Probably it's related with incorrect work of audio device (drivers). 1. Try to create a MP4 video. Will it contain a correct synchronization? 2. Do you observe any audio synchronization issue when you watch a movie in a video player app, a video clip in PTE preview, and video on YouTube? Find a point where you can see a face of a speaker and hear his voice. 3. Also try the attached test project to check audio synchronization. I use this test for last 15 years to check every new PTE version for audio synchronization. SyncTest.zip

Thanks for your opinions. We'll try to make it as in earlier versions.

If this problem occurs on one computer only, try to update drivers for audio device.
