I created subclips in the media browser, assembled them into a timeline and trimmed them for content.

#1 - When adding transitions I got the 'insufficient handles' message. Which is strange because it should really shorten the transition to match the media that is there. (It does this when dragging transition from effects library).

I then right clicked on the subclip to 'edit subclip' and 'use full clip extents'.

#2 - This killed the waveforms (is there a 'generate waveform' like PP?).

#3 - On one occasion the audio disappeared entirely, on another the audio playing on the timeline did not match the original edit (e.g. there was audio playing where there was no clip on the timeline).

Undo was my friend.

Same here with audio tracks in edit subclip. Additional info: If I extend the subclip, initially the audio track is not modified; sound is still there, but no change. Waveforms disappear. Trying something else leads to a totally different audiotrack in this place.

In Fairlight one can see the original audio track, even if in Edit the subclip is deleted. The only way to delete the track in Fairlight (it does not show in Edit anymore) seems to be: slide the tracks to another place in the Fairlight timeline; then they disappear.

Extending subclips by changing timecodes leads to no change in Edit but in Fairlight the change is visible.

After more experimenting Resolve hangs and quits completely.

My experience with 16.1.2 and subclips is similar:
To keep clear my media pool I populate it with subclips, so I don't have to slice long footage while editing.
If I edit a subclip restoring the full clip extension flag while it's still in the media pool, there is no issue when I put it in the timeline. I can extend it and edit without problem.
On the other hand, if I place a subclip in the timeline THEN I want to extend it by editing the subclip, weirdness starts.
After extending the end of the clip, clip audio plays up to the end of the original subclip then it keeps mute. Video is visible anyway. If I want to extend before the clip, maybe only the audio track by dragging it with alt key, then audio becomes out of sync. If I try to shift the audio no way it keeps out of sync no matter what I try.
I tried to drag the subclip from the timeline to the preview monitor and extend from there but no result.
The only solution was to extend the original subclip in the media pool and replace the one in the timeline.
So far, this caused me to lose a couple hours to re patch an edit, for now I'll wait using subclips because they're unpredictable. Hope this will be addressed because they're so useful (the concept).

Hi

Following from my answer in viewtopic.php?f=33&t=106632#p589839 :

Subclips are designed specifically for you to treat parts of the same underlying media file as different logical pieces of media - i.e. allow for distinct keywords, clip attributes and other media properties. It's as if you had obtained a whole rendered track as a single mov file and wished to deal with each scene separately.

If you wish to just mark edits and want to retain handles for the clip, please consider using duration markers - it keeps the media as is (common clip attributes, embedded audio, mattes etc) and adds the marker solely as an edit.

Thank you Ramani for your reply,

I fully get your point. Maybe i tried to bend the subclip to a behavior it's not designed for.
Anyway i'm wondering if in future releases the subclip concept can be stretched to something "extended", because it's a very nice tool for getting up fast with a project.

As example, when importing long footage in the media bin, i find useful to review the footage in the preview panel, mark in/out and drag into the media bin, then repeat until i extracted all needed sections from the footage. The dragging operation creates a subclip, hence the misunderstanding.

Thanks.

Umberto,
I am not sure you extended the intended use of subclip too far.

I already described the fact that deleting subclips in Edit does not delete the audio track in Fairlight. Thus, Ipresume there is a conflict within Fairlight between the (not deleted) track and the new, extended audio track. Or something like that. In Fairlght you can see the original track placed 'on top of' the extended track.

Interesting fact is that you can extend the subclip (after choosing edit subclip) without problems 'to the right, but not 'to the left''.
Another interesting experience is that sometimes, on selecting 'edit subclib', the menu shows only 'cancel' and 'edit full clip' selected. After cycling the selection (edit full clip off-on), the subclipo can be edited without any problems, both video and audio track.

Perhaps this helps to find the problem/bug, which I think it is, primarily because of the first observation: not deleting the audio track in Fairlight.

I can't observe the issues you describe - so some additional information on your workflow would be useful. Apologies in advance if some clarifications tend towards the pendantic.

Please specify you have enabled layered editing, are viewing layers and if you have linked selection on.

Could I confirm that you're using subclips - i.e. media created in the media pool / source viewer using "Create Subclip" ?

When you say extend - do you mean with original clip limits (after Edit subclip)? Or subclip limits?

And on "does not delete the audio track in Fairlight", do you mean to say that when you delete the video subclip you see the audio bits of the edit left behind? or do you expect the track (e.g. A3) to be removed alongside the deleted audio clip?

"without problems 'to the right, but not 'to the left'' - when editing a subclip, do you check the use full extents checkbox or do you edit start and end manually?

Thanks for the responses

Dear Shrinivas,

First my answers:
I mean: subclips made in the source viewer.
With extend I mean to extend the subclip limits (after Edit Subclip command). This is not beyond the original clip limits. I use the full extend option in Edit Subclip.
In Fairlight the audio bits do not disappear, as they do in Edit (neither does the sound) I do not expect the track to disappear. I use 'track' for what I can see of the clip.


Just to be sure I gave the right information I repeated a test. Restarted computer and Resolve.

1)A section of a full clip (synced audio) selected using source viewer, selected subclip (in Bin). Video and audio linked (and keep this linked).
2) copied subclip from bin to timeline.
3) edit subclip --> full clip extend selected.
4) Extend the clip (using the mouse) in the Timeline. The audio waveform disappreares, video extends normally. Audio signal is still there but unaltered (not extended like video). Undo does not bring waveform back.
5) In Fairlight the audio track reflects this: an unaltered audio track. There is waveform and sound.
6) Back to Edit and truncate the subclip (instead of extend). Both video and audio show this, but the sound is still there (no visual track left). This is consistent with Fairlight; the track is still there, unaltered.
7) In Edit delete the (sub)clip (video and audio still linked, both disappeares), In Fairlight: the audiotrack is still there, unaltered from the original. Sound is still there.
8) Audio track in Fairlight cannot be deleted. It can be moved to another track and then it disappeares.

In my experiment of today I found out that the subclip in the bin is editable and if I copy this clip to the timeline, I can make adjustments there. Extensions are also copied to Fairlight, showing as a separate clip (unlike in Edit). If I delete the subclip in Edit, In Fairlight the original audio stays, the extension is deleted.

I mentioned a difference 'to the left' and 'to the right' in my earlier post. I was not able to show that again today.

I hope this helps,

Tamis

Checked Studio 16.2: Unfortunately, this issue still exists.

I'm also experiencing the same issue which is making the use of Subclips which is essential to my process very difficult.

1. Create Subclip in Media Tab
2. Add Subclip to Timeline
3. Right click clip and select Edit Subclip
4. Check use full clip extents (I need to use part of the clip before or after the subclip in out points)
5. Subclip loses waveform and audio

A fix for this would be huge for me!

UPDATE: It looks like this issue was "Resolved" hehehe in the newest update. Thanks BMD!
