PTE Video Optimiser was designed as a standalone app, useful as a complement/addition to PTE AV Studio, and useful for a wide audience of users. Some features from PTE Video Optimiser already have been ported to PTE AV Studio 12. For example, video export in AV1 (WEBM) format and support for vertical video export. Video stabilization and noise reduction cannot be performed with highest quality in real time (they require significant CPU and GPU computations). Stabilization works in 2 passes for the best quality. These features can only be implemented for video export. An important feature of PTE AV Studio is that all our effects (except Motion Blur) work in real time and are available in a fullscreen preview, in the EXE shows, and in the video export. Stabilization is the most complex feature due to its 2 passes, which must be precisely timed. Integrating it into PTE AV Studio will be even more hard than in PTE Video Optimiser. Yes, I'd like to see stabilization/noise reduction functions in PTE AV Studio, but right now we're not ready to implement them. Sorry.

Hi, Thanks for sharing!

Hi Mark, You can use a free license key for V12 Beta. Please read my 1st message in the following topic: https://www.pteavstudio.com/forums/topic/52130-pte-av-studio-12-beta-3/

I reproduced this issue. Thanks.

Bruno, thanks for your suggestion.

You can already add your own sound files to your projects - just use the "Add Sound" button (not Sound Library) and select your local audio files. We plan to expand our built-in sound library. However, we only include sounds under CC0 (Creative Commons Zero) license - meaning they must be in the public domain and free for everyone to use without restrictions.

Hi, Thanks, I reproduced the issue by replacing the Sound file. We'll fix it. Temporary workaround: remove the existing Sound object and add a new one.

Hi Mary, Thanks for checking video editing functions. Please send me this video file which causes freezing and incorrect speed. Better with a project file (.pte). Write me a personal message with a link. I found a couple of issues with editing of video speed and duration. We'll fix it.

Gary, Frame interpolation is always applied to the entire video object, from start to end. For example: A. The original video is 30p. Your display operates at 60 Hz (or you are creating a 60p video export). Video speed is original, 100%. PTE will generate intermediate frames (1 real frame + 1 blended/interpolated frame) for the video object. B. The original video is 60p. Your display operates at 60 Hz (or you are creating a 60p video export). Video speed is set as 10% / 0.1x. In this case, PTE will generate 9 intermediate frames (1 real frame + 9 blended/interpolated frames) for the video object.

I initially applied loudnorm normalization (for all sound files in the library) using the EBU R128 standard with a target level of -16 LUFS. loudnorm с I=-16 in FFmpeg. I noticed a problem - some quiet sounds get to the same level as loud sounds, destroying the natural dynamic range. Probably I'm wrong and I can try again. UPD. I normalized all audio files in the sound library in future Beta 4.

Dave, This is the default sound library included with the program. We'll continue to expand it. Users can add any other sound files to a slide/transition through the Open file window (by clicking the Add Sound object button on the top toolbar).

Gary, Glad that you found a reason with the issue with a wrong offset. Currently Sound objects are not displayed in the timeline of the editor as waveforms. Probably in future version. The main idea of a new Sound object is to play short sound effects (1-3 seconds). Examples included in the Sound Library which appeared in Beta 3.

Gary, try the simplest thing: 1. Add a video with fast motion in a scene. 2. Set speed 5-10% 3. Tick the option "Interpolate frames". Then create another version with unticked "Interpolate frames" and compare results in a fullscreen preview.

Yes, that's correct for V12. When video speed is not 100% or when you add keywords, the sound is muted automatically. The same was in previous versions (for speeds not equal to 100%). We plan to enable sound for the modified speed, but I'm not sure how long it will take to write this code.

Hi, In PTE AV Studio 12 we added the Sound Library with camera shutters, clicks, page turns, and whooshes. Install new Beta 3 to try his feature. You can also add your own sound files. Adjust the volume and offset from the beginning of the slide.
