My lab is experiencing the same issues as @lrighter while working with 720p video files, 5-60 minutes in length. No apparent relationship between video length/size/encoding standards and these issues.
I have three RAs who are working with the files on their own computers. Two have M1 Macs, one has a 2019 Mac. I am also working with a 2021 M1 Mac. We have exactly the same issues with freezing and crashing, inability to select annotations, lag loading the viewer, and using our controlled vocabulary. These are better for the student who’s not on the M1 Mac but they’re a problem for everybody, including her.
Besides what Lilli mentioned, we’re also experiencing these issues in segmentation mode and annotation mode:
- Video playback is choppy or lags
- ELAN becomes unresponsive and users have to force quit. This is resulting in users losing all of their work even if they have manually saved several times - I assume the autosave function is overwriting what they manually saved
- Audio is in a separate file from video. When hitting play in segmentation mode, audio doesn’t play from the timepoint where the cursor actually is, instead plays from another timepoint (nowhere nearby)
- Audio plays, but cursor doesn’t move, when hitting play in segmentation mode
I’m having my students downgrade to ELAN 6.2 to see if we can resolve these issues.
