MOV vs Image Sequence when Keying?

When I render as an MOV, it seems the output already had an alpha and it's easy to comp layers in After Effects. I've rendered a couple shots art Image Sequences and then imported them into AE only to find the file doesn't seem to have an alpha channel. So I need to go through a rather tricky background key removal (tough when i character has wispy hair). Any thoughts on how to remove a background when rendering as an image sequence. Or is the moral to this story just render as a movie?

    If you were saving as JPEG or BMP, these formats don't have an Alpha channel.

    If you use PNG or TIFF you should have the Alpha.

    I use After Effects, and my advice is to render as a movie. I only use Keylight in After Effects if I really have to. Wispy hair is a pain in the bottom. (The majority of the characters I've used in the past have short hair, hee hee. )

    It doesn't matter if you use .mov or image seqyences as long as the video fornat or image sequence supports an alpha channel such as tif or png.
    I always render out tif images from Daz for import into AE. One benefit of using image sequences is if you have a creash in the middle of a render, you can always re-render from where you left off. You can't do that with a video format.

    I believe After Effects defaults to .mov so I find that format seems the easiest to work with in AE. .As AniMajik stated Tif or png should also work if you want to render out to an image sequence.

    Not from AE, but from DS. I always output quicktime (animation codec / lossless) from AE and FCP.
    I can always convert the uncompressed QT to whatever I need for deliverable.

    BTW, AE defaults to whatever you used last. So if your last output setting was image sequences or whatever, it will use that until you chage it.
