and do you know AE’s color management down to a ‘T’. Do you understand proof views, the difference between SRGB and HDTV, cineons, RED linear light, 32bpc, gamma 1.8 or 2.2, LUTS,legal luma and chroma values,etc. If you don’t, read Adobe’s white paper on it and read Chris and Trish Meyer’s stuff or no super computer is going to help you…

[Chris Wright]

well, redrocket for RED acceleration for sure, a kona 3 2k for editing and output, and a nice radeon card(nvidia’s crash with kona and redrocket at the same time), a broadcast quality monitor with a spyder calibrator(or something equavalent/better), and about 32gb or more ram for AE, the fastest raid 5(or bigger) with tons of terabytes, the fastest intel chip you can afford, um what else, others please chime in. Basically, the more RAM you have, the more RAM preview playback lengths you can enjoy.

ok i think this fixes it, it’s about 90% perfect, so add a slider to the layer to edit rotation.

name your puppet pinned rectangle “End 2” and paste this in rotation of the arrow.

Now you can use a dummy system so that you can parent objects, and the code will ignore the puppet pins and always auto orient to the layer being called to.

follow2 = “End 2”
diff = sub(position,this_comp.layer(follow2).position);

(Math.atan2(diff[1],diff[0]) * 180/Math.PI) + 180+effect(“Slider Control”)(“Slider”)

my project doesn’t work when your not using circular motion. so why can’t you keep it simple, precompose the arrow with the bar and use starch at 100%, so it won’t bend there and put the pin on the arrow instead???

here ya go Dan…

A fully rotating, positional box always lined up perpendicular with a stretching, bending rectangle. It has 3 querks:

1. it needs at least 3 keyframes. 2 isn’t enough to extrapolate an angle.
2. it needs a one frame pre-roll and post roll to compute.
3. There can’t be any sharp changes in the keyframe graph view.

It’s an ae cs3 aep

I’ve named it impossible.aep lol

v=thisComp.layer(“Blue Solid 1”).effect(“Puppet”).arap.mesh(“Mesh 1”).deform(“Puppet Pin 1”).position.velocity;
radiansToDegrees(Math.atan2(v[1],v[0]))

and pickwhip the positions

[Chris Wright]

sure, but couldn’t you get direction data by comparing the previous position data keyframe to get a direction? that’s pretty basic. I’ll see with what I can come up with.

[Chris Wright]

I don’t fully understand the question, but Dan, can’t you use this expression from particular to turn the x,y toworld data into rotation data? something like this…

v=effect(“Particular”)(“Position XY”).velocity;
radiansToDegrees(Math.atan2(v[1],v[0]))

AE with or without plugins? Anything is better than no plugins(even including Kona) What’s the best? Terranex!

search the cow here for the 444 and 422 gamma issues which can be fixed. Dbeta is a different comp size than DVD output, so chose 486 if you’re directly outputting to Dbeta or you’ll lop off the bottom pixels which is NOT cool.

I hope you mastered your red to prores 444 and not prores 422 or you just deleted a bunch of chroma.

Why would you output your footage to digibeta which is 720×486 not 480 which is dvd output only.

I would definately compare different resizing methods such as AE’s, virtualdub’s bicubic, topaz ,and red giant’s resizer. You can either fit to comp width or fit to comp height depending on if you want black bars(enhanced mode) or letterbox(crop mode)

SD would be rendered out lower field because it’s NTSC. I’d recommend https://wwwss for 3:2 pulldown which is the standard for dvd mastering. Also, hopefully you know about interpreting the red stuff as hdtv(if that’s what you set it up as in red originally conformed) and 32 linear light off. Then master out the output module with color management sdtv so that the color also gets conformed.
