Subclip problem : partially displaying media offline frame

After years editing with the pancake workflow and stacked timelines, I'm trying to use a subclip approach to have sort of a "media bin view" to ease my work.

So I found how to create subclips at derush time. And now I have a whole set of subclips (without extent), which is nice and more visual than a timeline. So far so good !

But as I'm trying to use the Cut page to take advantage of the speed editor, I see some unexpected problem. Subclips are displayed in the source tape each with the whole clip duration, and the missing part displays the Media offline frame. So it's really hard to navigate and I've no idea what a workaround could be.

I couldn't find anything on the forum or anywhere else about this problem. So any help would be much appreciated ! Thank you

I also tried to edit in the Edit page with the subclips, and I'm very confused with their behaviour. I think there's a major bug with subclip without extent generation.

I'm currently using the last version DaVinci Resolve Studio 18.1.1 build 7

From one clip and my I and O marks, I generated 2 subclips: with and without extent, as shown in the following screenshot.

In the bin
The subclip without extent is right to use as the thumbnail view shows only the part of the clip I want to keep.
On the other side, the subclip with extent shows the whole clip with I/O marks and is difficult to use. If the playhead goes beyond the marks, the thumbnail can show any excluded frame and make it useless at edit time.

In the timeline
The subclip with extent is inserted with a right duration : the part I want to keep. I can use the trim edit mode to restore content if I need it. Perfect !

The subclip without extent is inserted with the whole clip duration. The part before I mark is present. The part after O mark is shown as Media Offline. Totally unusable.


May someone help me with this ?

Exactly same issue here. Proper subclips (no handles) show either partly offline (or fully offline), even though the media files are present (right click on reveal in media storage takes me to full file). These are created with Match Frame (F) and saving with alt-B. Subclips with full handles don't do this (created by dragging from Timeline directly into a bin).

The proper subclips are the only ones with useful thumbnails (as the thumbnail is from within the used part).

Which computer and which sources?

I don't use the Cut page, but I wonder if you're trying to conflate disparate work flows here, Yann.

I'm thinking if you're gonna use Source Tape on Cut, you just don't need Subclips. Make your selects right from Source Tape.
