Thank you all for your answers. I ended up saving it as sequence of frames and programmatically creating a video out of the frames with a fixed frame rates. The newly created one does not have the duplicate issue. I guess the camera I used to record was not using a fixed one to start with.

@JimmyRustle I did try that as well, but surprisingly it still saves duplicates. I'm sure the original video does not have any though. @C Major according to the information displayed on VLC, the frame rate is 30.006134. But even if I try to set that as the frame rate in the export, it still produces duplicates. Does that mean my original video has a variable framerate ?

Thanks for the answer. It's actually not only trimming. I also add some effects (crop and zoom) on the video. I tried with lossless export but it says that my video do not meet the requirements. I even tried with the raw original video (without any effects added) and still same error message

Hello, I am trimming some videos using Videopad in order to make small clips of them. However, after I export a clip with "autodetected framerate" and then use a programming script to save individual frames of the clip in my drive. I realize that there are frame duplicates in the sequence. I need the frames to be unique otherwise that would be creating noise in my data. I tried different export options but it seems like Videopad keeps duplicating some frames. Is there a way I can export a clean video with no duplicates? I already thought it might be a problem inherited from the original video but I checked and the original one does not have any duplicates. Those are clearly introduced by VideoPad for some reason. I hope someone can give me some good solution. It will be too time consuming if I have to manually remove duplicates. Thanks a lot
