Why VSE Preview Text Editor should be implemented
It's hard to use text strips in cases such:
Text strips will require using more than one of them or creating images with text in image redactors.
We intend to add basic text editor options to make it easier to use Blender for simple text formatting cases.
Our text editing options will be in the preview window so there will be a clear distinction between sequencer text options like color and size that can change over time, and static effects such as bold, font, etc.
Text editor features
Effects that are set for the whole text strip and may be changed in time:
(all already implemented in the text strip)
Extensions that we want to implement:
bold, italic, strikethrough, underline, etc.
Roadmap
There is no specific time for testing because it has to be done every time a feature is implemented before assuming it's done.
Phase 1, preparation:
GUI will:
Phase 2, editing with selection:
Phase 3, alignment:
Phase 4, effects:
Phase 6:
Blender VSE Text Editorto Blender VSE Preview Text EditorFYI, this just seems to be an issue with the current UI not allowing you to enter a newline symbol or escape sequence. If you run something like
C.scene.sequence_editor.sequences_all["Text"].text = "abcd\nefg"
in a script editor, you'll see that multiple lines already work as expected.Wouldn't it be possible to release this feature in smaller PRs, leaving out less critical features for later?
Not only to allow earlier testing of the basic features, but also to avoid reviewing a huge block of code all at once.
@mod_moder, I assume that the "Text Editor" label is only intended for the Text Editor from this module. Our project will implement a text editor for VSE, and these are two different text editors.
@RedMser Sure, more smaller PR's would be best, though considering size of base feature - to edit text in preview, the PRs would be likely large.
@fsiddi since we have talked about this, here is outline of what should be implemented.
Great to see the very limited text strip options being addressed. This is something I've tried to work around for many years in add-ons.
Consider adding mock-ups of the UI early, since many projects dead-ends on the UI design.
IMO, there is no doubt that the optimal solution would be to have a text implemented as a Tool in the Preview, which will work like a text tool commonly known from image editors. This is what users would expect of such a tool. You select the T tool, click in the Preview to set the position, type away, set anchor, adjustable wrap area, and in the sidebar set font, alignment(center!), kerning, styling etc. And even animated presets (as assets in the asset browser?) could be implemented.
As an early step, the current text entry widget was recently changed to the search template(TEXTEDIT_UPDATE) which is updating the text while you type, an alternative version of this widget could be made where the return key would enter a line break \n character, so users would actually be able to look at the Preview while typing and see the line breaks being inserted immediately. (The X for clear string could maybe also be changed to a Return button). Or alternatively, implement a simple multiline text widget with a scrollbar (it could also can be used for the 3d text and multiline node texts).
Better integration of the VSE with other editors in Blender is also a thing. And we already have the Text Editor and the text data block, so it could be considered to have an option to link to a text data block as an alternative to manual text entry option.
However, these two elements are editing pure text strings, and the question is if each character should be styleable, as mentioned, how can these two different text types work together? And what system will allow for individual character styling, mark-up, json, html or an entire and complicated animateable system based on string positions(ex. individual characters changing to individual colors over time)?
