Where can I find detailed information on how to edit recordings in Adobe Connect

If you double click the crop bars, they go to exactly where your play head is.

If you need a more granular edit, you can download the source files of the recording (I would do it after having at least one edit in the recording) by adding /output/yorunamehere.zip?download=zip to the URL for your recording. Then you should see an edit.xml file (if edits are present in the recording), where you can put in the edits at whatever timings you want. You will need to know where the edits go before doing this, as it is a blind edit. Then rezip all the files back up and upload to the connect server to have a duplicate version of the recording, with your edits.

Other than that, there is not much that can be done to get a more specific edit.
