post hub


CASTAR is the result of the collaboration between Antoine Vermeesch, senior post supervisor, and Manon Martin, senior VFX compositor.

Not a standard post-production company. 

Being a small company, we love to work alongside with directors, producers and artists. Our policy is to collaborate as closely as possible with you and creating teams adapted to your needs, whether with freelances or by subcontracting to other Belgian or foreign companies.

CASTAR has a strong relationship with some of Belgian’s leading creative talents in the form of colorists, VFX artists and post-production companies who work closely with our team to ensure each project reaches its full potential. We find the right fit for your video production and budget. 

We can of course oversee the post-production and handle VFX but also do ourselves most of the Digital lab processes. You can reach us for films, series, documentaries, video clips and especially projects off the beaten track. We have  a passion for cinematic storytelling, stunning visuals and always strive for high end products.
