This sounds like a rare issue I've seen a few times involving embedded timecode tracks in video files (which Isadora doesn't seem to like for some reason).

Try this:

1. Launch Isadora
2. Open your problem Isadora file
3. Go to Help > Generate Media Report...
4. Open the resulting text file
5. Search for "Time Code Tracks:"
6. If you find any video files where a timecode track is listed, find those media files and move them to a different location (like your desktop)
7. Next, re-export any problem media files without the timecode track, but with the same file name as the original media files
8. Put the newly-exported video file in the same folder as the rest of your media so that Isadora will find the new media file and load that in instead of the old one
9. Quit Isadora
10. Relaunch Isadora
11. Test out your file again

If this is the problem I think it is, the steps above will solve the problem.

Without being able to reproduce an issue ourselves, we can't make or test a fix for an issue, so I've been trying to get a sample of problematic media that causes this issue in the 3-4 cases of it I've seen over the past three years or so. Unfortunately, in every case, after I solved this problem for someone, they didn't respond to my request to provide me with the problem media, so we've been unable to reproduce (and therefore fix) the issue.

 I've had trouble with JPEG's which are really large in the past. If they're big ones, try making them as small as you think you can get away with.

Are your files on your local drive or on Dropbox/icloud/other?

Did the files work before without issues? If it has happened overnight something must have changed between then and now (programmers adagium). 

I suggest looking at all of the media and make sure the Resolution is ALL THE SAME.  I have had this happen to me, and fixing the resolution to the same did it.

I'm having an emergency. I have a whole show file that maybe has been corrupted by some bad files. I have a step back version but it's a whole day of work. The files that gave me error message are just jpgs which seems really strange...I've never had that happen before...is it usual. I also have one video file that seemed to be corrupt but when I removed it, nothing changed. The effect of all this was that the video feed was advancing, but the scenes in isadora weren't. So I was seeing something projected that was not on screen...and that seemed bizarre. And then the engine basically just froze. They're finishing a run (dress rehearsal) so I can't problem solve right now...but once I get my computer back can anyone suggest order of steps to quickly solve this problem. Do I need to step all the way back to the previous day's file?

Thanks

@woland Thank you L this is an alternative solution which I hadn't thought about. I'll check this out too. Many thanks!

You could use Cheetah3D to make actual 3d wheels with numbers on them, then use the 3D Player actor to rotate them and the 3D Stage Orientation actor to position the "camera" in the right place.

@dbini Hey John many thanks for your wise words. I will try out the Ease In/Out actors. If you have time to elaborate on your "conditional logic" comment that will be much appreciated.

Thanks again! 🙏

Hi Simon. 

Ease In/Out might be better than Envelope Generators, giving you the inertia feeling - it might also be easier to set up with conditional logic to enable you to trigger different destination years.

Hello Isadora community I hope you're all well.

For an upcoming production I need to project the four numbers of a particular year, for example: 2026.

Each number needs to be presented independently in a smooth vertical scrolling slot-machine format. The closest example I can think of is Apple's iPhone timer.

In my mind the Isadora scene will fade up with each of the four numbers scrolling vertically, independently, with an element of inertia to replicate the Apple feel.

I need it to be programmable so that each number comes to rest correctly in a sequence for the year in question.

The production will require this to be replicated several times in different Isadora scenes, however, each scene will display a different year / sequence of 4 numbers.

I've made a start and included the file: scroll-txt-test.izz

Perhaps the way forward is with some python code or Javascript but I'm no coder.

I would really appreciate any thoughts / expertise on how I can formulate this process.

Many thanks and best wishes,

Simon
