A. Importing markers directly to source masterclips is not supported by Media Composer. You need Interplay & our Desktop Logger app to import markers directly to source masterclips.
Importing markers directly to the sequence is supported by Media Composer. You can take the text file output from eLogger & import this on to the sequence. This is done via the "import makers" menu within the marker window.
Amend the sequence timecode to match the timecode of the masterclips. Once imported you can copy and paste the markers from the sequence to a clip loaded in the source window.
Importing via Interplay directly to masterclips is quicker & efficient when working with lots of source clips compared to importing via the sequence.
