Settings of 60fps or a 30fps 1080p output. Up to 100 hours of total videos when done. Hour mp4 files by filming a 3D printer printing a model. I generally get 20-100 hours of video from my Sony video camera in about 10 The version of OpenShot I've got now is 2.4.4. Possibly troubleshoot some issues with OpenShot. What you need to find the error at 16X speedup? I'm not asking you to fixĪnything as I've found my solution. I know it's lengthy, but details might be I need to give you a rundown of what I do to edit since it may help youįigure out the black frames. Hence the reason I am trying to reduce to medium quality.ĭoes anyone know why these black frames are being created and is there a way to stop this from happening and ruining a hundred hours or more of work? But those also take about 120 hours to export the file and is often too big for YT video at 200G or more. The high quality exports don't have the unwanted black frames. So apparently the reducing the export to medium quality triggers it to happen. I have done one huge video in high quality and this doesn't happen then. There are hundreds to thousands of these black frames added so redoing an edit to remove them isn't practical. Needless to say with 20-40 hours of editing then waiting up to 80 hours for the final product and seeing Openshot insert these black frames is disheartening and many hours of wasted work. Each place/time one of these black frames was added, it appears as a flash to the viewer. When I analyze it by looking at it frame by frame, I see lots of blank black frames added into the otherwise good video. Sometimes flashing only once sometimes 4 or more times. About every 4 or 5 seconds the video will flash a lot. The video itself is correct and looks great except for one really bad fact. This takes about 80 hours of waiting for results and produces a video usually around 2G-3G in size. I then export with the 1080p h.264 60fps settings in medium quality which is about 5mb/s. Then I add a music soundtrack of nearly the same amount of time and truncate it to match the video end. If I had any audio in the video, I remove it. I can view frame by frame and it looks OK but the system can't play the video preview without skipping. I can see the video on the timeline is now about 20 minutes. I first apply a 16X speed increase then a 2X speed increase to achieve this since there is no 32X setting. Usually there is no sound or I will overwrite the sound track later. They then would produce about 20 minute videos in the same h.264 1080p 60fps. I'm wanting to take these really large (100G to 2T), H.264, 1080p, 60fps videos and timelapse them to 32X the normal speed. I then edit and post my lesser quality edited videos that are time lapsed to 32X faster (about 20-30 minute video) on YouTube. But they are too high of a bitrate and length to easily stream. These unedited videos are nearly perfect and have no frame errors or issues. I'm a 3D printer and my unedited video footage of a print can be 10-48 hours at 1080p 60fps h.264 50mb/s.
