v3.5.3 - The new 60i de-telecine to 24p feature is not working. There is no obvious tickbox to activate detelecine, so I can only assume it is supposed to happen automatically when changing frame rates.
Output still has duplicate frames, dropped frames, and sudden motion.
Input video was previously sent on this topic, but my post no longer appears.
Input & Output is attached.
See my user profile for Mac system info.

Click “Edit” next to the input resolution and there is a checkbox of [x] TELECINED. If you check this, it will add fieldmatch, bwdif (I assume as a fallback measure) and decimate filters to the FFmpeg command. If you select ffmpeg command from the submenu in the list of jobs, you can see the what the [x] TELECINED checkbox is adding. This should convert “24000/1001 in 30000/1001” back to “24000/1001”, ie inverse telecine or IVTC.
It is implemented as a checkbox that declares/defines the characteristics of the input as telecined, rather than defined as an obvious process of inverse telecine. I hope one day that Topaz will expose the real filterchain as a graph, much like FFmpeg Filter Visualizer or LAVFI Preview which would help visualize what is going on under the hood within the filterchain.
I don’t know why Topaz chose fieldmatch,bwdif,decimate in preference to FFmpeg’s pullup filter, but it was probably for a legitimate reason based on their internal testing.
Great to see it added as a much needed option. It is likely to work best when the source is of strict cadence, rather than mixed-progressive-telecined-interlaced content, often found in documentaries or where the titles differ in scan type to the main content.
Wow…yeah, that was hidden really good.
That was prrrrobably not the best place to put this checkbox.
Thanks everyone!
