thought i'd share another shot from the docudrama
http://www.rileyharmon.com/temp/boys_preview_done.jpg

working on animating the model-t, revamping the lighting, finishing some rotoscoping, shooting some by-stander footage, etc

enjoy...

ps.. other shots here... http://rileyharmon.com/wordpress/?p=53

Wow,

although I don't know so much about digital compositing and stuff (just read these boards out of curiousity, and maybe, once in a while, learn something new), I think that really looks good! Nice work!

Very nice.
Care to share what techniques you used? Looks like at least some (maybe lots of .. ) roto ... were you able to use some luma information to help with a procedural key?

The signage and lighting in the current comp don't appear to be entirely consistent with the era. ;-)

Any chance of seeing this in motion?

Hi Riley,

Fairly good work, although the perspective is so different on the two shots, that it's very noticeable the two characters don't match with the new vanishing point. In your comped image, the characters should be lower in the frame and larger. Try drawing an invisible grid on top of your scene to find out where the vanishing point is.

i did set up the ground plane when doing the match move, the camera pans to the left as the boys walk up. I've already rendered out a test to see how the perspective matches, in the moving shot it looks great, but that still really makes that bad angle show up, im def aware of it, nick...lottts and lottts of roto, ive been looking into some kind of wacom or alternative to make it easier, maybe even this http://www.touchscreens.com/mt17pc-usb-b.html

I use a Wacom for mattepainting in Photoshop, but generally stick to mouse for adjusting roto masks. The Cintiq would be realllllly nice, but even the price a used Wacom was a bit of a stretch for such a specialized instrument for me. :-) I'm not roto specialist by any measure.

One thing that I have found really helps with roto is to break up the task into multiple masks. For this shot, that might mean 6 masks, (head, body & legs for each character). This helps compartimentalize adjustments and work so tweaking something around the shoulders doesn't have to impact the work already done on a hat for example.

Looking forward to seeing your progress on this.

oh i definitely broke it up, head, body, 2xlegs for each boy. just thought an on screen pen or wacom might make things a little less painful

I'm being nosey, but what programs are you using for this?

I find a tablet much faster for roto... it you move the points like you are "drawing", the tablet is just a lot faster. i.e. use your hand/eye co-ordination such that: you know beforehand where the points are going when your hand moves a certain way. It's not completely accurate (zooming helps), but I find it much faster... and a roto mask doesn't need to completely accurate anyways / it's extremely difficult to get it 100% accurate anyways.

right, im using ae for my rotomasks and then doing -1 mask expansion and 2px mask feather, i just hate the mouse, so painful
