Dear MEA5 users, thanks for checking out the forum 🙂
Some words regarding the new versions of MEA:
The basic functionality of MEA is still available for free. You can use these free versions on Apple as well as on Windows.

The Apple-version with extended features is available from the App-Store
The Windows-version will run in extended mode for 14days, then the extended features require a license.

Pricing information:
As mentioned above, basic MEA5 is still FREE 🙂
These are the extended features:

Hello Dr. Ramseyer,
I am using MEA 5 on Mac, on both Sequoia and Sonoma OS versions, and the program will not process videos past approximately the 100,000 ms mark. I am wondering if this is a known issue, a limitation of the basic version, or perhaps related to older Mac chips (M3).

I have tried running basic 5-minute recordings through the software, but the output consistently ends at around 80,000 ms (±20,000 ms each time). I have also run your test videos through MEA 5.3 (only the first 8 minutes or so), and the same issue persisted, with the output only covering the first 100,000 ms or so. In all trials, two ROIs were defined.

The manuals appear to be for MEA 4, and I am unsure whether slight changes in the functionality of the new version, the OS, or the M3 chips in our Apple computers could be causing this.

Any help would be greatly appreciated. Much love to the MEA team — thank you for making such a user-friendly program.

Hi salamander2 🙂

Thanks for reporting this important issue!

I have tested MEA5 on macOS 14, 15, and 26 and have not been able to reproduce the problem so far. It is very helpful that you used my test video, because this allows us to largely rule out a video-codec-specific issue. The Apple Silicon generation should also not be relevant, as I tested MEA5 on M2 and M4 systems.

One possible explanation could be App Store sandboxing, although I am not yet sure whether this can actually cause the behaviour you observed.

I suggest that you send me an email at mea@psync.ch. I can then provide you with a direct download link to a version outside the App Store, so that we can test whether the issue is related to the App Store build. In parallel, I will continue looking into other possible causes.

Cheers from Bern, Fabian

The issue is fixed in version 5.04:

Fixed the output index for analyses of existing video files. The previous “t_ms” column reflected elapsed processing time rather than video time. It has been replaced by “frames”, indicating the number of processed analysis frames. Existing movement values from version 5.03 and earlier remain valid.

For AppStore users: Please update your version of MEA5
For Windows users: I am working on an easy way to update MEA5 for Windows. For the time being, please ignore the variable “t_ms”.
