Sorry for the newbie question. I shot my video on a 5d Mark II, holding the camera like shooting a portrait, and so the video straight out of the camera is sideways. I want to rotate the video and do my color correction in after effects, but my 1920 x 1080 comp means that I have to scale the video way down to fit it. It feels like I'm losing most of the video as I scale down.

I tried changing the comp from 1080 x 1920, and the video fits this, but something happens and it looks as if the video is skipping frames once rendered. I don't know what happened. Any suggestions?

When you say skipping frames, is this during playback, and when you rendered what kind of file did you make? If it's a quicktime, you can check to see if it's skipping frames by using your arrow keys and go through the video frame by frame or just bring your rendered file back into AE and see if all the frames are there. If they are it's most likely a playback issue with your CPU(rendered files can often be way too large to play correctly on a computer).

See this from adobe: : Why is my output file huge, and why doesn't it play back smoothly in a me...

Unless you're shooting for an installation with a vertical monitor, video is always landscape, not portrait.

Because you held the camera sideways, your video is now sideways. If you rotate the video on its side, the viewer would have to rotate their displays to see it correctly.

You can scale down to fit your video in a standard 1920x1080 frame, but your video will now be 608x1080, with with 656 blank pixels on each side. (This is called pillarboxing.)

You can place your 1080x1920 video within a 1280x720 comp, scale it up 18.5%, and crop off about two-thirds of the frame vertically. (This is called center cutting.)

Honestly, your best bet is probably to reshoot with the camera in the correct landscape orientation for standard video displays.

If you are getting funny playback of the footage that seems as if it is skipping frames... I can almost guarantee you are trying to work with the H264 the 5D records in. Convert your footage to Apple Pro res or something else and AE will like you more.

The higher they fly... the much.
