When I rotoscoped my file and cut it to timeline length all files are visable with eye just not in timeline.

I rotoscoped this image. When I cut timeline to composition length all my other files became invisible with the eyeball still selected. The fire layer in the second picture is one example of an invisible layer.

it appears your layers in the timeline are far back as if you trimmed the duration to the work area that was forward in time after your layers end points. this is quite messy. first thing I would try is hit multiple undo's to when you had your layers visible in the timeline. if Undo's won't cut it (you go 99 undo's unless you cleared all it manually) the hopefully you are keeping backups and auto-save of your project files, now is the time to see if you have the most recent project file before this happened.

I have reverted back to a saved copy of the project. Now I have to rotoscoped again. When my tutorial instructs me to trim layer to composition length. That's when all the other files vanish.

Where the time indicator is is the clip I need to trim down.

o.k good hold it right there. the tutorial instructions probably tell you that because it's assuming you have one layer in your timeline and probably instruct you to work efficiently to just the duration you need. that's a lot of assumptions on my part and since I don't know which tutorial is it, it could also be bad or unneeded workflow instructions (because every one can make a tutorial). this trim may not be necessary (more about it later). but to achieve a trimmed comp to the duration of your footage when it's already in another composition with other assests, you can  just precomp the footage ctrl+alt+c and choose this:

this will create a composition with just that footage and adjust the duration to the trim. inside you can make the roto work if you want. I am not even sure you need to trim it, unless you plan to composite things inside making this a composite shot that will be easier to focus on if it's in it's own composition

It worked thanks for the help!!!!
