I've been looking for the answer myself for the last 3-4 years and after doing a lot of research(internet and otherwise), I am finally now a student of Seneca College(Toronto, Canada), but I had my own reasons and restrictions and the case might be completely different for you(so read ahead before making any decisions).
Here’s a list of schools that I considered, and the positives and negatives that I weighed before shortlisting Seneca -
1. Gnomon School of Visual Effects, California (USA) - http://www.gnomonschool.com/
Well, I like calling it ‘Kind-of-a-Big-Deal’ School! One, It’s hard to get in! and Two, It’s probably the most expensive out there. I spoke to 2 of their alumni and they spoke very highly of it, not just that, their showreel speaks for itself -
Negatives – Really Expensive
2. Academy of Art University, California (USA)
The only school(now, SCAD does too) I know of which offers a master’s degree(MFA) in visual effects. This was a sure-fire choice for me, it’s not that difficult to get in and its not that expensive either. The only reason I didn't go for it is because they don’t recognise 3-year degrees(most US universities don’t) and hence were offering me to enrol in their undergrad program(which I wasn't interested in). Every year they have a huge showcase of their student’s work and a lot of students are hired by renowned employers on this occasion.
Positives – Master’s degree in VFX, yearly student showcase attended by BIG studios.
Negatives – Doesn’t recognise 3-year degrees
3. Savannah College of Art & Design(SCAD), Atlanta&Savannah (USA)
SCAD, has very recently started offering Master’s in VFX as well(In fact, i wasn’t aware of this before writing this article). I didn’t even try applying as it was really expensive!
Positives – Master’s degree in VFX, An established brand name.
Negatives – Doesn’t recognise 3-year degrees, difficult to get in.
4. Sheridan Institute of Technology, Oakville, Canada -http://cfprod.sheridaninstitute.ca/program_micro/pcanm/
Now, Sheridan is known as one of the best animation schools in the world! but, according to my research, their VFX programs are not as good! Frankly, since I was keen on doing VFX from Canada, I was confused between Sheridan and Seneca(my final shortlist) but then a few reviews from alumni of both the school made me decide on Seneca. The review from the Sheridan grad was great as well but I couldn't find many showreels of this the graduates of this program online(as opposed to Seneca). Also, it is slightly more expensive than Seneca. Both of these colleges offer an 8-month PG diploma in VFX, which, depending on your situation might be good or bad!
Positives – An established brand name, not that expensive
Negatives – not many student showreels online(I could only find one)
5. Seneca College of Applied Arts & Technology, Toronto, Canada - http://www.senecavfx.com/
I got to talk with a lot of Seneca-VFX graduates and all of them said nice things about the program and professors. After one semester, I am glad I made the right choice. The professors are really amazing and are all working in the Industry so they keep us updated about the latest tools&techniques. Here’s their latest Students Showcase -
Negatives – Not as easy to get in.
5. Vancouver Film School(VFS), Vancouver, Canada - http://www.vfs.com/
Hands down, the best VFX school. EVER! But, its so expensive that you might think twice before even thinking! That being said, there are a lot of student showreels online to watch and all of them are phenomenal. Also voted as the ‘Best 1-year 3d Animation and VFX program in the world’ by 3D World Magazine.
Positives – A HUGE brand name, a lot of student show reels online, recommended by almost everyone.
Negatives – EXTREMELY EXPENSIVE(international students)
6. Bournemouth University, Dorset, UK - http://ncca.bournemouth.ac.uk/courses/?sub=41
Bournemouth is a pretty famous university but there master’s program in visual effects is completely based on programming and technical troubleshooting rather than making(or breaking) stuff.
Positives – One year Master’s degree
Negatives – technical course, requires a technical background
7. Escape Studios, London, UK
Escape studios is known for offering short-term intensive courses in visual effects, in specific VFX fields(compositing, etc.)
Positives – Short-Term courses, In-house Studio
Negatives – Really Expensive
Final Thoughts – Being an international student I was more bent towards Canadian Schools than US or UK schools because of the easier immigration laws and usually cheaper tuition fees. You get to work for 3 years after a 2 year program in Canada which might not be the case if you study in UK or the US. Getting a job in the field of visual effects totally depends on your portfolio, so as long as you are dedicated towards a great looking portfolio you WILL get a job no matter which school you are from(or even home or internet-schooled).That being said, I chose Seneca for its in Canada(easy immigration laws), its not-that-expensive and the great alumni feedback.
