[Richard Garabedain] “I don’t understand. we are slowly upgrading our computers to windows 10. But what we did not know was that once you open a project in AE 2019 windows 10, it cannot be opened on other computers or saved for earlier versions. “

You have never been able to directly open a newer AEP from an older version of Ae.

You can save down from Ae 2019 to Ae 2018 via File > Save As > Save a copy as CC (15.x) — I know this works because I just did it yesterday — but of course if your project is dependent on a new feature in 2019, that will not work.

Did you get a specific error message?

If you want to loop that set of keyframes endlessly after the final keyframe, use

loopOut(“cycle”);

My recommendation: make the rectangle with an open path — just two points — and a very think stroke. Add the Trim Path animator, then link its End property to your slider.

Can you show a screenshot or two of what you’re trying to do so I can try to explain in the context of your project?

An “offset” loop accumulates; it loops the segment you specify, but it offsets the beginning of each loop segment from the end of the last one. A picture might be worth a thousand words:

loopIn() works before the first keyframe (and when you’re defining a range, counts keyframes forward); loopOut() works after the last keyframe (and when you’re defining a range, counts keyframes backward).

You’re using the Lossless output module, which is excellent for archival but bad for playback (unless you have an extremely fast hard drive). Try encoding that AVI to a more playback-friendly format like H.264 with Adobe Media Encoder.

This should be pretty trivial to script. What’s the format of your CSV data? Can you post a little sample that shows what the CSV export looks like?

[Kevin Han] “But I guess what I don’t understand is MOST of the time, my Disk Usage is at 0-1% when previewing a scene (which is contrary to what I said above)… and then it’ll all of a sudden spike to 50-60% for a few seconds not before going back down to 0-1%… Or sometimes even a disk usage of about 95-100%..? Might happen for about 5 or more seconds. It seems the Disk Usage happens in spikes and only for about a few seconds all while previewing out a scene.”

I suspect that Ae is moving cached frames from disk to RAM in bursts for playback.

Use the modulus operator — it returns the division remainder:

time % 10

[Kevin Han] “I’m working on 5-10 second compositions but a lot of motion graphics, layers, effects, and AI files. I’m pretty new to AE and so I don’t get what you mean by doing “very little computation with a whole lot of footage involved.” Could you give me a scenario as to what this may look like? Not sure if I fall into this category lol.
“

You are most likely to be CPU-bound. You don’t have a lot of footage you need to read off disk. If you were doing the Brady Bunch opening with 9 streams of 4K ProRes footage, you’d be hitting the disk hard every single frame.

[Kevin Han] “Also, could you recommend me a performance monitor software/app where I am able to monitor my disk usage?”

On Windows, check out the Performance tab in the Task Manager (Ctrl+Shift+Esc). From there, you can open Resource Monitor for more details.

On macOS, try Activity Monitor.
