Image sequence to video - edit trouble in FCPX

Have taken some time-lapse sequences. Edit in Lightroom and rendered in AE (best settings and lossless).
It's around 240 images and 10 second video. It's quicktime-format and around 700mb.

Before FCPX update I had no problem editing the videofile, but after the update the clip, or the preview turns black whenever I do any changes to clip. And often it takes some seconds before it comes back to normal. Editing is a nightmare. Had to run the sequence through encoder and render it to H.264 to be able to work with the file in FCPX. But then again. The file is heavily compressed.

So, why is this happening?

Have the iMac 4.0ghz M395X and 8gb ram.

"(best settings and lossless)"

Could you give the complete specs of this including the codec?

I wonder if it would be worthwhile to attempt to use Compressor instead of AE in order to convert the images to a video file.
Compressor File/open image sequence

Then export to Pro Res and edit away in FCPX.

If that works it might point to some sort of compatibility issues between AE and FCPX.

You should be able to export to ProRes at an appropriate frame size and frame rate directly from AE.

I agree. In After Effects export to a 1920x1080 ProRes 422HQ Quicktime. If you really want uncompressed quality, use the ANIMATION codec, not Uncompressed. But you'll be hard-pressed to notice much (if any) difference. Either way FCPX can handle that just fine.

Maybe it sounds stupid - for me old QT Player is still the best choice for image sequences.
No re-crompression, fast and flexible.

Ahh well, I figured it out.

I chose ProRes, and now it's easy as.

Best settings and lossless is standard if I doesn't choose anything. But now I will go for ProRes. So much easier to work with in FCPX!

I tried QT player, but I couldn't figure it out. Then AE came, and since I need to do some editing and stabilization in AE I chose AE. Thank you for your help!

Sorry my bad. With "old" I meant QT Player 7. Use "Open Image Sequence ...", select frame rate and save either as reference or self-contained movie.
As said it's fast, doesn't need re-compression, and a ref movie is flexible, since you can change individual files of the sequence.

The problem with doing it in Quicktime itself is that if you're importing shots from a DSLR and the resolution is 25 megapixels per frame, you're not going to get a video file that plays back with any kind of speed or consistency. BUT you can export that into a weirdly-shaped ProRes file (since DSLR shots aren't 16:9 or 4:3) and that should help.

Why wouldn't you get speed or consistency? I have been shooing time lapses for years with a DSLR and converting that to ProRes video files with QT7 very successfully. Or maybe I'm missing the point?
