Operators

Add Transform	Delete	Mouse Track	Set Cursor 2D
Adjust Alpha	Duplicate	Pixelate	Track Transform
Autocrop	Grab	Rotate
Call Menu	Group	Scale
Crop	Meta Toggle	Select

Add Transform

A transform modifier must be added to a strip before the strip can be scaled or rotated by this addon. If you're planning to make keyframes to adjust the scale or the rotation, ensure that you are modifying a transform strip by adding one with this operator.

Shortcut	Function	Demo
	Add Transform

Adjust Alpha

Shortcut	Function	Demo
	Begin alpha adjusting
	Round to nearest tenth
	Escape alpha adjust mode
	Set alpha, end alpha adjust mode
	Set Alpha, end alpha adjust mode
	Set alpha to value entered

Autocrop

Sets the scene resolution to fit all visible content in the preview window without changing strip sizes.

Shortcut	Function	Demo
	Autocrop

Call Menu

Bring up the menu for inserting a keyframe. Alternatively, you may enable automatic keyframing.

Shortcut	Function	Demo
	Call menu

Crop

Shortcut	Function	Demo
	Begin/Set cropping, adding a transform if needed
	Escape crop mode
	Click the handles to drag
	Set crop, end cropping
	Uncrop

Delete

Deletes all selected strips as well as any strips that are inputs of those strips. For example, deleting a transform strip with this operator will also delete the strip it was transforming.

Shortcut	Function	Demo
	Delete
	Delete strips and remove any other strips in the timeline with the same source. For scene strips, the scenes themselves will also be deleted.

Duplicate

Duplicates all selected strips and any strips that are inputs of those strips. Calls the Grab operator immediately after duplicating.

VSE Transform Tool 2D only create animation for transform but not origin

VSE Transform Tool 2D only create animation for transform but not origin.
So it wont present rotate and scale animation correct.

Blender 2.93: no attribute 'use_translation'

When I try to grab or select this error happens:

Python: Traceback (most recent call last):
File "/home/aobatroz/.config/blender/2.93/scripts/addons/VSE_Transform_Tools-master/operators/grab/grab.py", line 328, in invoke

Using a proxy resolution breaks crop in 2.82+

The crop function works correctly when no proxy resolution is used but breaks when Proxy Resolution is used(on Movie strips, but Color strips still works):

On a different note, I've made a fork and implemented toolbar buttons for the main Transform Tools operators: https://github.com/tin2tin/VSE_Transform_Tools When it is finished, I'll send you a patch:

The VSE maintainer expressed interest in having the main Transform Tools included in Blender as either build-in python operators or as an add-on.

Discussion on the toolbar work can be found here: https://blender.chat/channel/vse

VSE Transform Tools do not behave the same in 2.8 as in 2.79...

Hello,

seems like there are some issues with this addon:

When the cursor is not in the preview window, the T command does not work.

Also when using the addon in 2.79, the distortion of the image (or video) was instantly removed, when adding the transform modifier, this does not work anymore in 2.8.

Thank you very much for your help,
Ralph

VSE transform as an official Blender add-on

Hi Daniel,

I've gotten in touch with the people working around the Blender VSE, and Richard, the maintainer. There's interest in having a few add-ons distributed as official ones, including the VSE Transform one. Would you be interested in having it distributed there? Do you still have time to maintain it?

If you need a hand with anything, please tell me.

Improvements for the Crop tool.

This is a feature Blender should have by default and for some reason doesn't, but I feel we could improve this just a little bit by adding two essential functionalities of any selection tool: Ctrl+LMB or Shift+LMB for "fixed ratio resize of the box", which could default to a square, and maybe some field to set a custom ratio if we wanted something else, like 4:3, 16:9...

I would gladly dive on the code to add it myself, but I'm kinda short on time, so I'm posting this issue just in case it is a problem that has been overlooked.

Allow changing opacity for all selected strips

Currently, pressing Q will adjust the alpha of only the active strip. Instead, alpha should be adjusted for all selected strips.

If the opacity is different for each of the selected strips, set the opacity of all selected strips to the Max opacity of them all and edit from there.

Error message while moving, scaling, or doing anything except rotating!

This is the error I receive when I try to move.

I receive similars error when I try to do anything else except rotation. I don't know why. I use blender 2.93.

Add-on not installing

Hi there. Happy New Year.
I am using Blender 2.80 in Linux Mint 19.
After installing the ZIP file, and when I click here: screenshot 1

Then I get this: screenshot 2

Also, when you click on Report a Bug it brings you here: http://openurl%28https//github.com/doakey3/VSE_Transform_Tools/issues)

Batch rendering a file with Transform Tools installed crashes on exit

In __init__.py, in register(), there's this line of code:

        km = wm.keyconfigs.addon.keymaps.new(name="SequencerPreview", space_type="SEQUENCE_EDITOR", region_type="WINDOW")

In a batch environment, where I'm calling the blender binary to make it render frames without starting up the whole UI, it seems that wm.keyconfigs.addon is None, causing an exception. It looks like the rendering actually happens but my render script thinks that Blender failed and keeps rerendering the same chunk.

I don't know if it's the right solution, but a solution is to test for None and exit early:

    if not wm.keyconfigs.addon:
        return
    km = wm.keyconfigs.addon.keymaps.new(name="SequencerPreview", space_type="SEQUENCE_EDITOR", region_type="WINDOW")

From bl_info at the top of the file:

    "version": (1, 2, 9),
    "blender": (2, 83, 0),

Blender v2.82.7 on Ubuntu 20.04

I have tried Removing the add-on, restarting Blender, and installing again but it didn't help.

when I add VSE transform tools to blender, there are some error info

Auto-update does not seem to work

When I tried to use the auto-updater for the add-on, it somehow doesn't work. It says something like "Redo Unsupported" and "Restart Blender to complete update", but when I restart, it still shows the same old version. I never had this problem before.

This problem started since 1.1.6.

Auto keying + VSE Transform Tools doesn't seem to use default interpolation setting in preferences

In preferences I have default keyframe interpolation set to linear, which works in the 3d viewport and in VSE when manually inputting keyframes for transform strips. However whenever I animate with VSE Transform Tools, it always seems to use bezier.

Keyframe doesn't Work on Alpha in Preview Window Without Adding Transform Strip

I understand that you can change alpha straight away on a movie strip in the Preview Window without needing to add a Transform Strip. However, attempting to keyframe Alpha by pressing I on the Preview Window doesn't work without the Transform Strip. I presume it doesn't work because all the options in the Insert Keyframe Menu on the Preview Window only work on a Transform Strip. But since you are able to change alpha straight away on a movie strip in the Preview Window without adding a Transform Strip, it would be good if I can also keyframe on the alpha in the Preview Window without adding a Transform Strip.

VSE_Transform_Tools disabled

The button to Track Transform is disabled, and I have no idea why.

I have Blender 3.4.1

Does not work with Blender 2.92 alpha

In Blender 2.92 alpha the patch D8393 is incorporated. The attributes use_crop and use_translation are no longer used and throw an error. The use of a transformation strip is also no longer necessary for standard scale, crop, rotate and translate opertions.

Doesn't seem to work with 2.92

When I try to use g in the preview I get the following error

Python: Traceback (most recent call last):
  File "/home/gavinok/.config/blender/2.92/scripts/addons/VSE_Transform_Tools/operators/grab/grab.py", line 328, in invoke

Rotation Locks up at -360 or +360

If the rotation of a strip reaches the limit (-360 or +360), the rotation function will no longer work.

Fixing this issue would require coming up with a different method for rotating strips. It could also be solved if Blender did not have the -360 or +360 limits. Since the rotate function works well otherwise, and seeing no important reason for there to be a rotation limit, I have submitted a feature request for this rotation limit to be removed.

How to activte the "Track Transform" UI. Tools submenu is always empty

Hello, I can't manage to get the "Track Transform" UI window appear. The Tool menu is always empty even if some tracker exists. Does this functionality work ? Is there any special procedure to activate the "Track Transform" UI ?
Blender version used: 2,82a on Linux Debian (Same behavior under Windows).

Add-on does not show up in Add-on list in the user preferences

Hey -
I just tried to install the Add-on but after loading the .zip, it does not show up in the list.
The files are copied just fine in the .config/blender/2.79/scripts/addons directory, but nothing shows up.
Tested on 2.79 and 2.8. A friend on discord could replicate the issue.

Testing on 2.91

Trying Transform Tools on 2.91:

• Crop seems broken again.

• Interpolation in Transform Strip: None = Fast(maybe this should be set as default value when adding a Transform strip).

• Maybe the first Select and move icon should be a select only icon?

• I wish there was a better crop icon.

• Should the reset options be exposed in the menu? (anything else should be added to the menu?)

• 2.91 will have multithreaded transformations, which have been detected to give a speed up of 3.5%

• There are discussions on moving all transform operations into the strip settings, so at some point the Transform strips may not be necessary.

Crop-tool is visual not correct

I like VSE Transform Tools: it makes Blender a usefull video-editor. I have a visual problem with Crop. My videofragment is 3840x2160x25fps and renderoutput is 1920x1080x25fps and you cannot drag the handles to the edges. See printscreen: this is the maximun cropbox.

add on does not appear in the add on list.

Cropping doesn't account for mirrored strips

Scale takes already scaled and interpolated image and scale it again, loosing quality.

Steps to reproduce and understand this issue

• Configure scene resolution to 720x1280 (portrait proportions)
• Import a 1280x720 image/video
  -- (Image/video is scaled automatically to fit in portrait shape)
• Apply VSE Transform Tool by pressing "S".
• Chage its scale to original proportion by pressing "Alt-S".
• Image is like:
  

Steps to avoid this quality loss

• Don't apply VSE Transform Tool. Instead of that, check "Offset" in "Transform" / "Adjust" panel.
• Change "Position X" to -440.
• Image is:
