This report was linked to a patch, which cleaned up the polls giving the impression of a broken sidebar. It also exposed the mentioned meta strip functions. In the VSE chat I posted a suggestion on how to make the Meta Strip range more clear and with your line of code the "Return" button could be implemented. So all of these things could be solved, but I'll leave it up to you guys.
The patch: https://developer.blender.org/D6913

The UI could show this more clearly, but it's not a bug and doesn't belong in the bug tracker.

I don't know the status is with this project, but I just came across @Campbell Barton (campbellbarton)'s commit which adds Tab to open/close a Meta Strip. This may be relevant if the same functionality is what is needed for Scene Strips? Here's the commit: https://developer.blender.org/rBSe68b7e6d876e2913c528484651aa06e0ea0502f7

It should only be in the Sequencer Preview Sidebar Tab called View - as it is only printing data in the preview. AFAIR it only works for Blender generated EXR files, saved with that meta data inserted. There was the same problem in the Sequencer/timeline sidebar and it was fixed by Sebastian(?), but I can't find the commit.

Continued in D6883

@Paul (Thirio) The Text Block Anchors icons mentioned above are now included in Blender. Maybe 'anchor' is a better name than 'origin'?

Abandoning this in place of this patch which just moved the Add Modifier to the Add Menu instead: https://developer.blender.org/D6876

cut_multicam needed to be renamed to split_multicam.

You need to drag the icon.

Having the "Show Cache" on actually causes a serious drop in fps over time - in ca. 20 sec 40 fps is lost(from 60 fps to 20 fps) - looks like a regression?
This does not happen when "Show Cache" is off.

Updated to include same strip-colors for the Light Theme.

I agree with @Harley Acheson (harley) - the duplicate icon doesn't make sense in ex. the Text Editor, where you'll have to click a duplicate icon in order to "create a new text data-block":

So + and - would work?

@Maciej Jutrzenka (Kramon) What's the status on this? If you need to discuss it, pleas join here: https://blender.chat/channel/vse

What's the status on this?

In D6466#152751, @Campbell Barton (campbellbarton) wrote:

Currently the cross is used for both remove and unlink (in the image, node editors, sequence strip scene, to name a few).
Where the meaning of the rubbish bin is always to remove, for this patch to make sense we should differentiate unlink-data from delete-data.

This has been added in 2.83.

Another patch(accepted) here: https://developer.blender.org/D6372

This is the same error message in 2.83 with far too many icons and far too wide line distance imo.

@Richard Antalik (ISS) Snapping the last frame of the dragged strip to the last frame of a strip on the same channel, imo should be considered a bug, because it is an illegal operation, which will always cause an overlap as shown here:

The Prefetch Cache is actually slowing strip-grab operations down that much(on large resolution video clips), that on a low spec computer, that it would feel like a serious regression. Of course you could switch it off for each grab operation, which is a far from optimal workflow.

An Attract python patch to color code strips according to their development status:

Even though this is an old patch, the need for it is still present. Ex. take a look at the ugly Time sidebar panel in the VSE for example. Having either SMPTE or frames in the widget and being able to type in SMPTE values would solve this.

NB. the red cursor position marker, properly needs to be corrected too, since it is not currently relative to the height of the scrollbar, but to the height of the editor:

Where do you experience that there is too much difference between the name of the operator and the menu entry?
This is the old code:

Re-added Modifier to Context Menu and renamed "Clear Fade" with "Delete Fades" and renamed "Crossfade Sounds" to "Add Crossfade", since it is only available with Sound Strips. And Removed the seperators between add elements.

A lot of opinions here, but a bit of research reveals that calling the current time indicator "Playhead" isn't limited to all NLEs, but also is used in ex. Houdini and Unity:

Color coding of clips is a fairly normal feature in most Video Editors out there.

Seems to be an quite important bug to fix in 2.82, no? And maybe this, somewhat related, export one: https://developer.blender.org/T57397

For whatever it is worth, eevee rendered scene strips are playing painfully slow compared to the playback of eevee rendered in the 3d view(gif):

Most functions in the Strip tab in the Sidebar will change values in the full selection if +Alt is pressed or by using 'Copy to Selected' in the right click menu:

Works as advertised. Very nice with the presets, too.

Though this may be implemented, the current implementation makes playback of eevee rendered scene strips that slow, that they are not usable:

If this patch is accepted, could it be committed, please?

Tagging @Nathan Lovato (gdquest) on this one though the problems may be lower level than using the API.

I wrote about the misalignment in the UI chat, and @Julian Eisel (Severin) told me to report it here.

In order to get the text selection in a more effective way, this patch needs to be implemented: D6377

That clip plays here at 18 fps when there is a resolution mismatch 1060 vs. 1080.
Using Movie Strip > Set Render Size(so render resolution fits source) the playpack rate jumps to 25 fps.
(Disabling Cache and Cache Drawing)

Looking more closely at this panel, one of the things I realize is that it is not possible to render proxies if non of the selected strips has a check mark in the Strip Proxy header. So in order to separate render proxy for active strip vs. all selected strips, would need a checkmark in the header of the selected strips header to add a check mark to all selected strips. And the Proxy and Timeline tabs isn't only for generating proxies, but also by the checkmark deside what strips should be viewed with proxies, or in other words you won't see the encoded proxy files by selecting their resolution in the Preview/View panel, you would also have to add a checkmark to all strips...

@Brecht Van Lommel (brecht) Sorry, but this is unrelated to hardware specifications, and may not cause a crash, but at some point someone will report that Prefetch Frames isn't working, and tedious triaging will have to be done, until it is figured out that it isn't working, because Cache Final needs to be checked in order to get Prefetch Frames to work.

It seems to be caused by an add-on. I notified the coder of the add-on.

Works well.

Execelent work here. This patch is a solid performance improvement.

• When changing 'Proxy Render Size' and no proxy files have been encoded, the image quality is changed, but the play back rate stays the same. If it has no impact on the play back rate, then maybe it is not needed?

@Eitan (EitanSomething) I'm not entirely sure what you did here, and what you want me to test?
Throwing some files around, it seems that the scaling of files with no encoded proxy files has been removed eg. the quality and framerate is the same no matter what Proxy Render Size is set. (Is this preview scaling to be used in a separate enum?)

@Campbell Barton (campbellbarton)

Maybe the feedback on the actual tools should be saved for later to get this committed asap, but I noticed a few things:

• In Sequencer/Preview mode the Annotation tool isn't working.
• Shouldn't the Annotations panel in the View panel be moved into the the Tool panel in the Sidebar, instead of the current pop-up?
• The cut types are called 'Cut' and 'Hold Cut' in the UI - not hard and soft.
• If the topbar isn't used, maybe selecting a new tool should auto-change tab to Tool, so the Tool options will become visible, even though another tab has been selected?
• The background color of the VSE toolbars aren't in consistency with the toolbar in the 3D View(needs to be darker).
