How work tracking for paint in 4k tiff

No funciona el tracking con secuencia tiff 4K no hay rastreo para borrar cicatriz en piel. o necesita algun setting?

It’s hard to see what is going on in your screen capture. Is the Mocha tracker failing after tracking a few frames?

Hello if it is correct just track 5 frames
if I generate a quicktime HD 1920x1080 if it works
I need to work with my 4k TIFF material
there’s a solution?

Can you tell me the exact size of your 4K footage and I will try on my machine?

the measure is 3840 x 2160 píxeles 23.97 FPS

Hmm, tracking with Mocha at 3840x2160 is working for me. Can you confirm that you are using Silhouette 2020.5.7 which can be downloaded from here: Boris FX | Downloads
