#4298: zoompan filter creates shaky image ------------------------------------+------------------------------------ Reporter: slhck | Owner: (none) Type: defect | Status: open Priority: normal | Component: avfilter Version: git-master | Resolution: Keywords: zoompan | Blocked By: Blocking: | Reproduced by developer: 1 Analyzed by developer: 0 | ------------------------------------+------------------------------------ Comment (by David): Adding bilinear interpolation to this filter to prevent the jitter should be increased to priority critical. The jitter makes the zoompan filter completely unusable for zooming into the center of a video. By default, it's so jittery that it looks like I deliberately added a shaking filter. For example, see this video I exported locally on VideoGen: https://app.videogen.io/view/ksabnn. Even with the trick of upscaling, zooming, and downscaling, the jitter is still noticeable when looking closely. I tried using the geq filter and doing the math for zooming myself, but this is significantly slower. How is anyone supposed to use the zoompan filter in its current state? Why doesn't zoompan have interpolation while geq and many other filters do? -- Ticket URL: <https://trac.ffmpeg.org/ticket/4298#comment:10> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
