Bug? Can't render video with only a generator for video

As Resolve doesn't offer to detect LTC timecode in pure audio clips.
So I tried to create a timeline from our multi channel audio recordings
to render and sync that for our multicam production.

a)
However the DELIVER tab doesn't allow to render anything that doesn't include at least
1 video track AND it doesn't allow rendering any timeline that only contains a generator
(SMPTE colors and a 10mV ramp) inside it's sole video track. For some reason there must
be a video recording present in the timeline (even if invisible).

Is this a bug that I should report or is it documented somewher as expected behavior?


b)
Resolve syncs all clips for additional cameras that don't share our LTC audio just fine using the audio channel.
BUT when I add this one additional clip it fails to sync any of these clips.
Not only does it fail to sync the additional clip to the others but all the other ones too!!!

You'll need to make that generator into a compound clip to make it actually show up in renders etc.

My workaround is to place a freeze frame with 0 opacity.
Any other suggestions will be welcomed.

The question was not about another workaround but if this is a bug or expected behavior.

Expected. Has been like that for many years. Resolve wants real footage.

You can export just audio. You don't have to include any video.

You can export just audio. You don't have to include any video.

But not as an MPEG System Stream.
I need something that I can re-import into Resolve and have the menu-item to set the time code from the LTC signal in one of the audio tracks.

Handed it in as a bug report.
Along with some others regarding syncing and a small feature requests.
