Alpha Channels From Cinema 4D Into After Effects

This is a tutorial (my first) on how to take renders from Maxon Cinema 4D into Adobe After Effects without having to use any green screen, just using Alpha Channel in the Render Settings.

1. First, select any objects that you DON'T want to appear in the render. Now in the objects menu bar select FILE >> NEW TAG >> COMPOSITING TAG and now in the bottom right you will see the Tags' properties appear, simply uncheck Seen By Camera. Now do a quick render and you will see it dissappears.

2. Go to your Render Settings, select RENDER >> RENDER SETTINGS >> SAVE >> then choose FORMAT >> QUICKTIME MOVIE. Now with Quicktime Movie selected the option for Alpha Channel appears, check this to activate Alpha Channel. Now render the file.

3. Open After Effects and create a New Composition

4. Go to the main menu, FILE >> IMPORT >> FILE and select the rendered file. Now it will come up with Interpret Footage where it looks at the alpha settings, be default it should be Straight - Unmatted, if not, select this and then click OK.

5. Once the footage is in your file library, drag it to your timelime to be automatically centred. You can now add layers underneath it to show that only the objects you left without the Compositing Tag appear over the layer under it.

Any questions feel free to ask! Any hints or suggestions to make the tutorial better will be great! Thanks.
