Workflow advice for simple animation
on Jun 1, 2016 at 10:39:21 pm

I'm looking for suggestions for a workflow to recreate the animated red dots from this video. https://vimeo.com/169014622

Ultimately I need a video (30fps, mov (h264), 720 × 392) showing the dots only with a transparent background. The original footage I'll be working with will have red dots, more opaque than this, with no outline, which is as I'd like them to finally appear too. I will then use it to layer it in Premiere.

I could import a still red dot asset into Premiere then individually animate each dot using keyframes and scale and position alterations but this would take me about 100 hours, so I'm here looking for alternative workflows. I thought perhaps there might be a way to isolate the red pixels from the background for example?

I'm posting this on the After Effects forum, as this is my preferred software since I have it and know it a little, but if anyone has any suggestions of other software I'm open to that too.

Btw I'm an experienced editor but an After Effects novice, just starting to learn masking and 2D animation techniques.

Thanks!

Little confused, does the video that you will be working on already have dots, or do you just want a technique for creating random dots that fade in and out?

Hey John - sorry if the description was confusing. That is the video I'm working with so yes it does have dots, but basically I want is to separate these exact dots from the background footage. The end result will be a video with the dots only, and a transparent background, no background footage. I'm hoping to find a workflow that saves me from re-animating the dots individually as this will take a long time. Any suggestions appreciated!

Are the dots a single color, if so you can create a key that dials in that color to isolate the dots. Then just invert the key. There a number of keyers in AE that can do the trick.

Nobody is being very clear here, so let me reiterate what the good people of this forum are struggling to articulate: the cleanest method to export a file so that the background is transparent is to animate the dots over a completely empty background. Then, export the video using a codec that supports an embedded alpha channel, which is a channel responsible for transparency.

The Animation codec will do this, as will ProRes 4444, and Uncompressed. In fact, here's a list of a bunch of codecs that will do this: https://www.digitalrebellion.com/blog/posts/list_of_video_formats_supportin...

Then you won't need to do any keying, which would be inaccurate, especially when the dots are fading in and out. Alpha transparency will allow you to simply put the video on top of whatever the background needs to be...and the transparency is built into the video image.

Hi Blaise, Thanks for the reply. Yes that is understood but I've said repeatedly that workflow ("the cleanest method: you refer to) will not work for me due to being too time-consuming having 3000 dots to animate. It's just not going to happen in the time available.
I am seeking other workflows which will cut down on that time. I've had some success with keying, but there is some blue in the rest of the video, so I get some ghosting from the additional blues throughout the image, which is not ideal. Perhaps there is no way around this but I thought it was worth asking anyway!
