shortcut: making frames from video clip

[Lessevolvedman]

Why don’t you set up to render as an image sequence of your choice in the render output module??

[Lessevolvedman]

or maybe i missread ur question and u wish to do this within AE, without having to render out as images then reimport…if so then my bad, cant help u out there..

[Nils Palmen]

yes, maybe i diodn’t explain myself fully … i wanna make a camera fly through … it needs to fly through diffrent layers … every one of this layers – is 1 frame of an actual avi. file that i made … so that’s what i need to know … if there is a simple trick to render a avi. clips seperate frames … so i have 20 seconds x 25 frames/sec = 500 still images … i wanna put these stills in 3d space – in a row – and fly through – so we get an animation with more depth – (at least i hope to make more depth)

so – the button the gives you all the frames from a video file … withouth having to render them all out one by one …

[Nils Palmen]

yeah, okay – render output module … format: tiff sequence … this one worked – only problem is that it renders them out in 4/3 format instead of the 16/9 i have my project in … anyone know why this happens? is TIFF sequnece the best one or you think another is better – jpeg for instance … btw lessevolvedman – i’m an even lesserevolvedermanner 😉 …

You could give the layer time-remapping,
give the time an expression like this:

startIndex=1;
thisComp.frameDuration*(index-startIndex)

You can also give the position an expression like:

startIndex=1;
position+ [0,0,100]*(index-startIndex)

to spread all the layers 100 pixels apart in Z-depth.

You should change the value of startIndex to the layer-number of your first video-layer.
So, if for example: your camera is layer 1, your lights layers 2-4, and you have some text on layer 5, you should change the value to 6 since the first video-layer is N

About you’re previous post: the 16:9 is probably just a matter of adjusting “interpret footage” your stills.

[Lessevolvedman]

interpret footage should be your prob with the images not looking 4/3

bah…filip beat me

[Nils Palmen]

yes okay – tnx for the expression tips …

i can imagin that this would be a pain to render .. i’m fairly new to AE so scripts and all that jazz sounds like countreymusic in my ears … . not familiar i mean.

but maybe i could cut of all the layers that iv’e fly throuh … so the computer will not have to render those anymore because i don’t use them anymore – and maybe there is a certain visibility happening – like the screen only shows layers 1-20 (or 50-70 and so on) … so would it help if i HIDE the other layers that arn’t needed (with an experession or something – (or maybe give them weak resolution) … so my rendering will be faster … . and the pc needs only 20 layers rendering at a time? … does it work this way? or will he compute them al anyway?

tnx guys, it’s helping…

Yeah Nils,

I was thinking about it a little more and came to the same conclusion…
Depending on how you place the layers you fly through in 3D, there could be as little as 2 layers needed/ visible at one time…

With some clever expression fumbling, the layers that are no longer visible could jump from behind the camera that passed them, to a new position behind the next layer, and also update their time-remapping so they now show the correct frame, in time before they become visible…
If that makes any sense. 😎

I did something like that once to create a quasi-infinite floor using about 4 large layers.

If you can draw a sketch or post an example project using solids, that shows how you want to move the cam, I could figure out the expressions for you.
