Why does After Effects need to render unmodified footage?

No, I don’t think that we have any pulicly-facing documentation about MediaCore.

Hmmm, I thought so too. Is there any reason for the lack of publicly-accessible information on MediaCore?
In terms of workflow, with respect to video formats/architectures/containers, we can lay them out in terms of the following processes –
1) acquisition
2) work space
3) deliveryI believe that process (1) is pretty much out of our hands although I prefer to work backwards; starting from delivery BUT that’s a non-issue for now and the necessary requirements can be accessed by aggregating and then interpolating the information, henceforth.
On delivery; on its various mechanisms and preferred routes, I believe that we do have a nuts and bolts solution.
It’s (2), as per above, where there seems to be a deficiency, with information, on how we can maximize efficiency, not only within AE but also across PPro and AME.
I bring this issue up because there seems to be a high preference towards QT (ProRes, DNxHD, Animation, Photo JPEG, PNG – CODECs) as a work space (digital intermediary) format.
I feel that users should be placed in a position where they will have a better idea how a choice for a DI will affect their workflow.

It’s not hard to play back a media stream. Nobody’s saying it is, but AE (like Shake and other compositing apps) doesn’t play a media stream. It actually generates new pixels for every frame and then plays those back. There’s no reason to play back a video stream in AE. That’s what video players and NLE’s are for.

Great rebuttal questions… would love to know the answer to some of these.

[Carlyle Gordon] OK, if it’s not hard, then why can’t you do it?
I think you misunderstood my last explanation. It’s not hard to play back a media stream, but that’s not what After Effects or any other compositing app is built to do (except, possibly, for Motion) because they are built to do compositing. Therefore they are creating new pixel data for every frame when you play stuff from the comp window. If you are creating new pixel data, you can’t play back a media stream.
[Carlyle Gordon] So I import video into AE and I want to use just a few frames from the video, I should download an app that plays video streams and has time code? Play in there and write down the in and out points and then go back into AE? What if I’m going to do some roto work and I want to analyze the motion in the clip? Same thing? What about for motion tracking planning?
AE does have a built-in media player. You can choose in and out points and drop the clip into your comp. No need for a separate program. You just can’t play back a video stream in your comp window.[Carlyle Gordon] What if I did an edit in Premiere and I plan to do some kind of effect like an explosion.
But the cool thing about Premiere is that you can just copy and paste the clip out of Premiere into AE. Or import the Premiere project into AE. Or choose the clip you want and choose to replace it with an After Effects composition using Dynamic Link.
That way you can use Premiere for what it’s good for (cutting and playing media) and After Effects for what it’s good for (compositing and motion graphics).– The Great Szalam
