Mocha hilft in der Post, Tracking-Marker zu entfernen oder Screens zu ersetzen. Die planare Tracking-Technologie funktioniert auch bei schwierigen Oberflächen.
Boris FX's industry-leading planar tracking and rotoscoping software – uses proprietary planar motion tracking technology to follow flat surfaces in footage, enabling accurate screen replacements, stabilization, object removal, and rotoscopy with significantly less manual keyframing.
What is Mocha?
Mocha is a specialized tracking and rotoscoping software by Boris FX. Its unique planar tracking technology tracks flat surfaces instead of individual points, enabling more robust tracking even in challenging situations.

Mocha is an industry standard for planar tracking and rotoscoping. Its PowerMesh technology for deformable tracking has significantly expanded its capabilities. From simple screen replacements to complex VFX shots, Mocha's tracking technology saves countless hours of manual work in post-production.
From the crafts
Perspectives
Director
Mocha macht viele VFX-Shots überhaupt erst möglich. Screen-Replacements, Sign-Änderungen, Objektentfernung – alles basiert auf dem Tracking, das diese Software liefert.
Producer
Mocha spart erheblich Zeit im Vergleich zu manuellem Tracking. Die Lizenzkosten amortisieren sich schnell durch effizientere Workflows in Roto und Compositing.
