  1. Hello, I have a very large video (27 GB) with a high resolution (4096x3286) from a microscopic experiment with slowly moving events, so the number of recorded frames is way higher than the speed of the event that we want to observe. I would like to import the .AVI file in Videopad Video Editor, lower the resolution and at the same time save only every 2nd, 3rd or even 50th frame, and then save it again. I browsed through the forum and found many topics on setting a constant frame rate, or cutting and trimming clips, but not about only saving every x-th frame in an easy way. Maybe I searched for the wrong keywords (skip frames, drop frames, etc.), but I could not find it. For example, in VirtualDub software, you can just set a counter to decimate by 2, 3 or more frames, but VirtualDub cannot deal with the very high resolution of the images (4096x3286) and the file size (more than 27 GB). So I would like to read in the .AVI file, reduce the resolution 4-5 times and at the same time, save only every 50th frame, and then export the video again (and potentially change the frame rate again, to see the event happening much faster). Are there any suggestions how to do this efficiently ? Best regards, Wim
  2. Dear Nationalsolo, Your suggestion does the tric. The quality stays preserved now. I used "Position" to centre + "Scale x 2", but your suggestion to use the Zoom option with aspect ratio 16:9 works better. P.S. Is it necessary to load the video in two tracks ? I used the scissors to split the video in two clips, then cropped the two clips (left and right), did the zoom to 16:9 and then did the video output to 1280x720. Thank you for the prompt reply and excellent answer, Wim
  3. Hello, I have recorded in OBS Studio a video with resolution 2560 x 720 (32:9), basically two screen outputs of 1280 x 720 next to each other. I want to edit now the video in Videopad Video Editor, in order to keep the left screen for a certain time, and then keep the right screen for a certain time, and write the resulting video to 1280 x 720 (16:9) resolution. When I open the video in the bin, Videopad scales the canvas to a size of 2560 x 1440 (16:9). I try to change the format to my own, by rightclicking the context menu and checking "Change Clip Aspect Ratio...". However there is no aspect ratio that satisfies my needs. 32:9 is not in the list. The workaround is not satisfying. In that case, I split the video in two parts. In the first part, I crop the right screen output and centre the left screen output. In the second part, I do vice-versa. Now I end up with a centred 1280 x 720 video, on a canvas of 2560 x 1440. I should now "shrink the canvas" to 1280 x 720, but that does not seem to work. I can scale the centred video with a factor 2, and then again export the video to 1280 x 720, but that clearly leads to quality loss. Is there a way to "shrink the canvas", or to define your own aspect ratio ? Thank you in advance, Wim
