after effects doesnt load my footage

[FeelingPrettyRed]

when i add footage to after effects, ;literally, open it up and drag a 10 second clip in, it will only 'load' roughly 50% of the footage, there is like a green bar in the timeline, this will fill up half, then cut off and loop the video, if i scrub upto this it will load the second half, but remove the part that was loaded, it basically has a mind of it own and whatever i do, i cannot get 100% of the clip to load, forget that even 50% to load, the thing is the entire video is actually there and with alot of messing around you can view the entire clip, but not in sequence. ontop of everything else ive got too say adobe is becomiung so jarring, i mean all that money and you cant even make 1 programme run smooth... but anyway, constant issue with this and media encoder, ive used toe cc cleaner tools, ive cleared caches and followed hundreds of suggestions, nothing.... devesatting tbh, because my clinets and boss are at my n neck 24/7 a day, yet its genuily the multimillion pound company where the issue lies. if anyone could help it would be super appreciated, im only trying to replace a sticker on a bottle on some 3 second footage, so far, 1 hiur, 3 forums and still cant even get the original clip to load, pathetic if im honest. (please see attached image for referance of issue)

I fail to see your point. Your screenshot shows a 1.15 minutes clip and 45 seconds of it are in the RAM preview/ RAM cache. This is perfectly normal, given how AE works. No offense, but this is really a case where you should start with the basics and actually read up on what RAM previews are and how they work.

Everything else will require proper system info, details about your preview settings, specs of the footage and composition and so on, none of which you have provided. Again, i think you need to start with the basics. Many things in AE cannot be understood intuitively and from your description it is clear that you expect it to run like a realtime editing program such as Premiere Pro und all circumstances, which AE simply is not.

After Effects does not play video from a file like a video editor.  Instead it builds each frame into your computer's RAM and plays from there.  The greenbar denotes how much of the composition is saved into RAM.  But like anything which uses a computer's memory, the playback depends on how smoothly your RAM loads and if anything else is using it too.

Things you can do:

• Don't expect to edit in After Effects - or at least don't expect to edit entire 90 second sequences in one go
• At the bottom of the Composition window, there's a drop down for Full.  Switch this to auto or half or quarter.  After Effects will keep build up lower resolutions of each frame.  This is much easier when trying time animations.

Also, your clip might not load because of a codec issue.  Try converting it in either AME or a player like VLC if AME doesn't work.

That's quite the normal for AE actually. However, turning on Cuda and allocating a good size for the cache has helped my preview to speed up a little. Have you tried it?
