// Green Screen CGI Video Production for The Legion

The Brief

Our clients The Royal British Legion recently commissioned us to produce a video to help promote the welfare work of the charity and explain more about what the charity does. Work on the project began back in April of this year.

We decided to opt for a CGI/green screen studio approach as this would enable us the most flexibility in post production in terms of backgrounds and environments. We then began drafting the script with the Legion team and planning the technical aspects of the shoot. Amongst the important messages to present in the film, the scale of the Legion’s welfare operation was a vital factor to communicate to the audience.

We decided on combining motion tracking with a custom CGI environment to ‘house’ the presenter alongside giant, key statistics to focus viewers’ attention. Another aspect to communicate was the Legion’s wide range of beneficiaries – from young serving soldiers fighting in Afghanistan through to injured veterans and war widows. This made choosing appropriate case-studies a complex operation.

Technical Aspects

Following a number impressive test shoots with the Sony F3 Super-35mm camera, we decided to involve it with our production. On this occasion we paired it with the AJA KiPro Mini external flash recorder to enable us to record native ProRes HQ at an impressive 180Mb/s; essential when working with chroma keying. We also called upon the services of a 18ft Jimmy Jib camera crane to add dynamic movements to the scenes and emphasise motion-tracked sequences.

The Shoot

The shoot took place in central London in mid-September and was shot in one day. The crew and case studies worked tirelessly in hot conditions to ensure the shoot was a success. You can check out the behind-the-scenes video here:

Post Production

Once our rushes were safely stored on our storage vaults, we set about cutting a ‘green edit’ to match the original storyboards and obtain client approval. We then handed over the scenes to talented Cinema 4D and After Effects guru Chris Chart who set about keying the footage and tweaking the 3D environments we’d created. One aspect we were especially pleased with was the 3D representation of the 2D Legion logo; it’s reaction to light looks great due to the glass-like materials employed.

Final Result

The rendering, keying and grading processes took around 300 hours, but we think it was worth it! Check out the final film below; we’d welcome your comments using the form below.


We had the pleasure of working with an inspirational group of people The Royal British Legion has helped in various ways, who gave up their time to repay the Legion for all they’ve done by appearing in the video and sharing their stories. Hopefully they will have contributed to many more people understanding the great work they do all year round.
