Stefanseiner Posted February 15 Share Posted February 15 Hello, I am using NCH videopad v12.35 on a Windows 11 x64 System and so far all works fine, But today I tried "picture in picture" for the first time. Different cams, both on 1080p 60fps Preview in videopad editor is fine but exported as "Youtube 1080p" videofile there is some annoying flickering black lines and artifacts at the scenes with the picture in picture Here are some screenshots https://abload.de/image.php?img=brastlaubsauger.mp4_s8kfw8.jpg https://abload.de/image.php?img=brastlaubsauger.mp4_swwejx.jpg https://abload.de/image.php?img=brastlaubsauger.mp4_s25cdi.jpg https://abload.de/image.php?img=brastlaubsauger.mp4_s4rfg5.jpg Does anybody know how I can fix this problem? Thanks and regards Stefan Link to comment Share on other sites More sharing options...
borate Posted February 15 Share Posted February 15 Install the current release. Your links appear to be inactive (404). If that doesn't help, go to OPTIONS | ADVANCED and at the bottom change the GPU Processor from default to None (CPU only). Still no joy? Share the project and someone will check it out. The process is easy, quick and can be done privately. Just follow these steps... Back up --- With your project on the timeline, click on MENU at the top-left. Click FILE|BACK UP PROJECT FILES TO FOLDER. Choose a folder and SELECT FOLDER. Upload --- Use a free server - Google Drive, MS OneDrive, etc.* - to upload the saved, numbered FOLDER. Do NOT upload the individual VPJ or export file. Get link --- Get a public link. If using Google Drive click GET SHAREABLE LINK. If necessary change "restricted" to "anyone with the link can view" Share --- Click COPY LINK | DONE. Paste that link here, or click the folder at the top-right of this forum to message it privately to me. It won't be shared. * Before uploading, right-click the folder, click PROPERTIES. Look at the File Size to confirm that it's not too big for the free space on the server. Link to comment Share on other sites More sharing options...
Stefanseiner Posted February 16 Author Share Posted February 16 Thanks for your quick answer. I edited the first post to fix the image urls. Is there no possibility to insert some pictures which are visible? Problem seems to be the GPU render engine, As you proposed I deactivated GPU renderer and started exporting video just with cpu and there is no flickering. I tried a second run with GPU render engine on but with other settings then default. My laptop has a (slow) intel gpu integrated at the chipset, and a fast nVidia GPU. The default settings in Videopad with two gpus is "standard" and I changed it to force using the nVidia gpu. But there is the flickering again. So my solution is: - using GPU rendering per default - when using picture-in-picture I will deactivate the gpu rendering Thanks and regards Stefan Germany Link to comment Share on other sites More sharing options...
borate Posted February 16 Share Posted February 16 How does it do if the built-in Intel GPU alone is chosen - if that's an option? Is there a choice in the PC's BIOS to select one or the other? Please try the latest release. Your links have content now. Images cannot be posted, but links to them can.
