Maybe you need to be more explicit about the way GDrive is used (how and
why).
From your description, I understand that the MXF file
in the video folder
is synced, but not the identical copy/hard link in the actual
DCP folder.
True, this will prevent a successful ingest at the remote site, as the DCP
is incomplete. This is, however, not a fault in DCP-o-matic, but an issue
with the Gdrive software - it seems to ignore hard links. The easiest way
to fix this is to manually delete the video.mxf in the video folder once
the DCP has been created. This should leave the previous hard linked
sibling in the DCP folder as a fully autonomous file. Still not sure how
and when GDRive will react to that change if it is running during the DCP
creation, but, that would be the first thing to try.
Of course, another way is to simply copy just the DCP folder to a GDrive
folder, and not create the full DCP-o-matic project folder immediately
within the GDrive folder. A second option that could possibly save transfer
time is to ZIP the DCP folder. While J2K usually can not be compressed by
ZIP efficiently, very often audio tracks contain loads of silence and
sometimes jusr deflating empty audio tracks will achieve noticeable
compression ratios.
If the DCPs created are small, another option would be to setup an FTP
server (e.g. filezilla) on the remote PC, as DCP-o-matic has a function to
automatically upload DCPs to an FTP server once conversion is complete. FTP
upload and folder sync are two different procedures, but at least for short
DCPs/small transmission sizes, there shouldn't be much difference in user
experience. I understand folder sync nowadays is usually easier to setup
than FTP through a router into a cinema.
We have seen strange issues when projects are created on Microsoft OneDrive
folders as well. I wouldn't rule out folder sync for DCP upload in general,
but one has to be prepared to run into issues and find ways to
circumnavigate them.

Dear Carl,
Our customer Mrs. Deickert is working with your wonderful tool to create
frequently DCPs for her cinema.
We created a remote working solution for, the Sony Server is connected to a
small PC with is continuosly connected to the Internet. First we tried
Apple iCloud synchronization to bring the DCP files from her Macbook Pro to
the Windows PC, now we switched to GDrive.
Currently we face the issues that the GDrive sync app does not sync two
files which are technically identical but have a different naming. I speak
about both the j2c and the file in the movie folder. I do not know why
during the export you save the video file with two diffenent names. Is
there a way to disable the second video export in the movie folder? As
GDrive is skipping the j2c movie file, the server does not allow to ingest
the DCP in a correct way. Do you have any idea?
Thank you and best regards from Munich
René
