Barry, It seems that PTE AV Studio is running while updating. Close manually all running copies of the program. Also check Task Manager, probably PTE AV Studio couldn't correctly finish its work and stayed in background. If it doesn't help, restart Windows and run update again. It should help.

Gary, Low quality mode will give really bad results. Even without HW acceleration. I very recommend you avoid "Low quality" mode and I'm even going to remove it from PTE 11. CPU encoder gives better visual results than HW encoder, especially at Medium or Low quality. With High quality a difference is less visible.

Gary, What encoding settings you use? Can you attach a screenshot? I used 1920 x 1080, High quality, 30p. When "Hardware acceleration" option is NOT used a visual quality of dissolving transition is very good and I see smooth playback even at 30p. Same result with video created in PTE 10.0.6 and PTE 9.0.22. With Hardware acceleration (NVIDIA) dissolves are less smooth at 30p and it seems to be an issue/quality of NVIDIA encoder. I get same result with versions 10.0.6 and previous 10.0.5. Producing 60p video gives smooth results for dissolves. I attach my test project and created videos: https://send.firefox.com/download/2a73e9bd6270bf2d/#nMbFdlvmYayxh_H6XzYp7w

PTE AV Studio 10.0.6 is available Dowload: https://files.wnsoft.com/pteavstudio/pteavstudio-setup.exe Or use Auto Update feature: Main menu > Help > Check for Free Updates. Improved compatibility for created 4K videos with Ultra HD TVs. Report Improved video encoding in Custom preset with “Bitrate” mode. The final bitrate more closely matches the one set by the user. Fixed problem with a wrong file name in Convert/Trim Video Clip function. Fixed problem with overwriting of a locked video file.

I'm glad!

Thanks for the confirmation, Ron! I'm going to release v10.0.6 officially today later. It will add a wide compatibility with 4K TVs.

Gary, Please try a new version: https://files.wnsoft.com/test/pteavstudio-setup.exe It installs as v10.0.6 Build 4 (in the About window).

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

Hi Daniel, We didn't change video encoder library since a final release of PTE 10 in October. It seems that this problem is not related with PTE. Hardware encoder just becomes unavailable. Maybe after certain update in Windows 10. I had this issue twice on my computers. After updating of NVIDIA Geforce Experience drivers the hardware encoder start to work again.

Hi Ron, Please install this version: 10.0.6 Build 2 (as shown in the About window). https://files.wnsoft.com/test/pteavstudio-setup.exe

For correct comparison of different computers it necessary to use same project and settings. Because speed of encoding depends on visual content of a project. For example, a series of still images with a cut transitions will be encoded much faster than animated images with panning and zooming.

Kieron, Send me this project - all files in a ZIP. I'll check it.

Ron, Thanks for the help with testing!

Ron, Thanks for your high appreciation! Please try an experimental version. The About window should display "Build 3": https://files.wnsoft.com/test/pteavstudio-setup-build3.exe Create a 4K video with HW option and play on Samsung TV. A resulting file should be larger on 10% than with previous version. Interesting to see if it helps. I have a guess that USB 2.0 speed is not enough for playback of 4K video with high bitrate. As an experiment, try to play same video files (which cause problem on Samsung) on Sony TV using slow USB 2.0 port.

Ron, Thanks for these results! We set a max limit of a bitrate for video encoding without HW acceleration. And it helped. And when Hardware acceleration is ON we can't combine a bitrate limit and encoding with dynamic quality. It's only possible to use Bitrate mode and set strictly desired bitrate. 60000 (KB) for case of your Samsung TV. Just and idea. Can you check another USB flash drive with your Samsung TV? The best variant would be USB 3.0 Flash drive (which has a blue color in connector area. Maybe we have a problem with slow reading?

Ron, Please try a new version: https://files.wnsoft.com/test/pteavstudio-setup.exe Check the About window. It should display: Version: 10.0.6 (64-bit) Build 2 1. Encode 4K video without Hardware acceleration, High quality, 60p. And check on both 4K TVs. 2. Encode 4K video with ticked Hardware acceleration and Medium quality, 60p.

Ron, I'll prepare a new test version of PTE with optimal 4K settings tomorrow. If it possible, please check it tomorrow on both TVs. Please also try 4K 60p video from iPhone 8: https://send.firefox.com/download/9d5b9800e8148706/#ju-xnD2eYYgVX68WFQerLg How it plays on Samsung TV?

Ron, Glad that your like quality of created videos! Can you check the following: Choose "Custom" preset. Cange a mode "Quality" to mode "Bitrate" and type 60000 (it will give 60 Mbit). Encode video with Hardware acceleration and check on your both 4K TVs. Let me know about results.

Hi, Normally this problem should not occur when "Synchronize soundtrack and slides" option is ticked (by default). What happens when you press Space key to pause the show - does the music pauses or continues to play? Can you check Sample Project (see the main menu > Help > Open Sample Project).

Ron, Please send me this project again (missing files). See the personal message.

Peter, I'm glad that the new version works fine. We're still thinking about H.265 (HEVC) support. Current disadvantages of H.265: 1. Encoding takes in 3x time longer than H.264. 2. Old computers and even not so old PCs can't play smoothly H.265. It requires GPU hardware acceleration for video decoding. For example, NVIDIA Geforce 1050 or newer.

Ron, Thanks for the details. I see on 1st screenshot that bitrate was set to high (109 mbit). It explains why your TV didn't want to play it. Probably we need to limit top level of a bitrate to fit for hardware limitations of Ulta HD TVs. But usually bitrate is much lower, I need to understand why the encoder chosen so high bitrate value. It may depends on high dynamic scenes in your projects (especially if it contains video clips). Please send me your project, all files in a ZIP, in a private message. Use WeTransfer.com or send.firefox.com services Can you also check other projects? About 4-10 minutes of duration without video clips.

Ron, Thanks for testing. Please make sure that you installed version 10.0.6 in About window. Check my project and try to encode your 4K video without Hardware acceleration: https://send.firefox.com/download/26fbe6f303554279/#x0Noc-dHOQ1q5JEkVLF95Q I used "HD and 4K video" option, 3840 x 2160, High quality, 60p.

Mark, Thanks for this info. We can't do anything for Crossover emulation. Only in native Mac version we can use fonts correctly.

Hi, We greatly improved video output in a new version 10.0.6 Beta. I ask your help to check if everything works correctly: Download Beta version 10.0.6: https://files.wnsoft.com/test/pteavstudio-setup.exe Improved compatibility of created 4K video with Ultra HD TVs. Improved smoothness of created 1080p video on some old TVs (2011 or earlier). Improved video encoding in Custom preset with “Bitrate” mode. The final bitrate more closely matches the one set by the user. Improved visual quality. Note, that a file size of a created MP4 video without Hardware acceleration option is now larger on 10-15% than in previous versions of PTE 10 using "Quality" mode, but still less than videos created in PTE 9. It means better visual quality in version 10.0.6. You can reduce file size adjusting Quality parameter in Custom preset. If everything is OK, we'll publish a version 10.0.6 officially.
