![]() The most frustrating thing is the empty output file with no error message, and that -ss and -t would be confusing to use, since the original input PNG image data has no timestamp-type information. ![]() This has been insufficient to get this command to work consistently, even though I've had the same commands work with other input frames. I've tried importing all images to GIMP, then making them all the exact same resolution, and then exporting them ass as PNGs with identical settings so that all frames are the same file format. ![]() ![]() The information I've found online has been contradictory and confusing. I tried a variety of different commands, and found that they sometimes work and sometimes don't, very inconsistently with different images, different browsers, different video players, and different video effects. What I want to do is use PNG image data to create a video running with each input frame lasting two seconds, and with motion interpolation or frame blending/blurring between frames, to create a slideshow with transitions between slides because I am learning ffmpeg for fun and to create videos from images to share online.

If you want to create a perfect circle from a rectangular PNG, then you'll first have to crop it to a square by using our crop png utility, and only then you can make it a perfect circle. To do this, select the circle rounding mode and round each corner by a radius equal to a half of its dimensions, i.e. If you load a PNG image that has equal width and height dimensions (the picture is a square), then you can turn it into a perfect circle. You can switch between the quadratic and circle corner rounding modes in the options. By default, corners are cropped along a quadratic curve line but you can also cut the corners along a circular line. This way, you can remove just one corner from the PNG or multiple corners at once. If you leave any of the radiuses empty, then that vertex won't be rounded. You can control the radius of every vertex in the options. This browser-based program rounds the corners of a PNG picture.
