Fixed a long standing bug in IMB_dupImBuf: refcounter should be better 0
within the duplicated ImBuf...
Finally removed this strange STRIPELEM_META mumbo jumbo.
On a way to asset management: made METAs behave like true input strips:
* proxying should work
* input filter options should work (including transform and color balance :)
* IPOs now work in replace mode
|
|
Fixed a bug with ibuf caching on startstill / endstill.
The new blend modes happened to force start and endstill to be rendered
over and over again. This could get very annoying especially on scene
strips.
We therefore now cache the original start or endstill ibuf seperately
and copy on demand.
|
|
Align StripColorBalance correctly. Should fix
[#8242] new feature "3-way-color-correction" won't be saved with blend file
|
|
This adds low resolution proxy support to the blender sequencer, so
that even HD editing should be possible on slower machines.
The proxies are stored as directories of JPEG-files and are only
activated, if you use preview-resolution rendering.
For your final render, just switch back to full resolution and
the original files are used again.
It enables even proxying of whole effect pipelines and scene-strips
(but you have to your own custom directory for file storage then,
since blender has no filename, which could be taken as a sensible
default directory reference)
|
|
New feature: color balance aka 3-way-color-correction aka lift/gamma/gain
on input (folded into byte -> float conversion, so _very_ fast in that case).
Interface is inspired from Rebel CC (but not as complete yet, you can't
choose white and black points right now).
Bugfix: clamp color seperated wave form display correctly.
|
|
This fixes several crashes with the new tstripdata_start/endstill.
dupli_seq was cleaned up as well as add_scene_strip (moved to a
seperate function)
New features:
* opacity can be used in replace blend mode
* the scene within in a scene track can be changed now within the panel
Also:
* [#7842] Note: setCodec in FormatTab disappeared...
should be fixed by this. (Not a big change, so I just commit and see :)

Fixed two issues with the sequencer:
* using blend modes with startstill / endstill in combination with IPOs
failed, since there was no room to store the composited result.
(It was stored into the same TStripElem thereby effectively disabling the
effect of the IPO)
If you have no idea, what this is all about:
A common case was: use a single PNG as a title, extrude and try to fade
in / out using IPOs.
* startstill / endstill are always displayed, so that one can change them
also on movie-strips and scene-strips.

Attention! Rather large sequencer rewrite:
* Implemented layer blending using implicit effects. (works like layers
in "The Gimp" or Photoshop.)
* Fixed Space-Bar start-stop in preview windows.
You can start playback using spacebar within a preview-window and it _works_!
* Fixed Flip Y (didn't work for float)
* Fixed premul (didn't work for float)
* Added IPOs to _all_ tracks. In blend-mode REPLACE it drives the
"mul"-parameter in all other blend modes it drives the effect.
* you can meta single tracks.
* moved "mute track" from "M" to "Shift-M"
* added "Shift-L" for "lock track"
* changed inner workings for Metas. Now all ImBufs have to use the
reference counting mechanism. (Only interesting for coders :)
!!! Really important change, that affects current files!
Since you can mute tracks and now there is real layer blending capabilities
in place, I changed the silly behaviour that chose the output track.
Old behaviour: if we have an effect track visible, use the uppermost effect
track. If there is _no_ effect track visible, use the lowest input track.
New behaviour: always use the uppermost track. With blend modes active:
work our way down starting from the uppermost track to the first
"replace"-mode track. This is the way the gimp, photoshop, basically _all_
other applications work...
So if this change ruins your day: please try to fix your files using
"mute". If this doesn't work out, I can still restore the old behaviour,
but I really hope, that this is _not_ necessary!
Rational: most people won't get affected by this change, since you can't
really do anything usefull with the (old) sequencer without at least one
effect track and then you are on the safe side...

Moved status info bar into panels. It was always shown on the wrong place...
Added anim-startofs and anim-endofs, so that one can specify the range of
_input_ that should be used.
There is a subtle difference to start-ofs and end-ofs,
which will show, when you use "Reverse Frames" or "Speed Control". Both
effects operate on the input-range and _not_ on the display range! Now
you can control both in a comfortable way. Only thing missing: a button
to copy start-ofs and end-ofs to anim-startofs and anim-endofs.
(Andy: that was the feature you missed, when storyboarding with the sequencer
and the speed control effect :)
Also: added File-Name and Dir-Name to redirect input as needed.
|
|
Reworked image / movie loading, to add the following features:
- Mute strip
- Lock strip (peach request :)
- Crop / Translate _before_ image rescaling
- N-keys editing of start, startofs, endofs, startstill, endstill
Added (currently disabled) data structures for
- proxy support
- strip blend modes (currently only "REPLACE" works, which always did :)
Planed:
- automatic FPS rescaling
- command keys to lock/mute a bunch of selected strips
(which would complete the peach request to lock tracks)
Caveats: now the N-keys dialog is four-tabbed. I think, we should move those
tabs into the panels dialog in the future...
|
|
Well, added unnecessary pad variables after a fight with makesdna...
|
|
- Seperated StripData into
StripData
TStripData
where StripData holds only image-filenames and TStripData holds
the working information needed for ImBuf caching.
=> Large drop in memory usage, if you used a lot of movie and meta strips.
=> Fixed bugs in "duplicate" on the way (imbufs where copied around without
taking reference counting seriously...)
=> Code is much cleaner now
- Added defines for TStripData->ok
Finally figured out, what the magic values ment and named them properly :)
- Got rid of Sequence->curelem.
Reason: very bad idea(tm) for multi threading with more than one render
thread. Still not there, but this was a real show stopper on the way.
|
|
Peach request: display last mapped frame in status bar of speed control
effect. (To come: auto-resize based on this information)
|
|
|
|
snapping to unselecrted strips didnt work (I didnt notice find_neighboring_sequence needed them to be touching, added find_next_prev_sequence to get the next/prev seq)
added select linked (L and Ctrl+L)
added Ctrl +/- select more/less
|
|
new option for the image sequencer's image strips, flip x/y, (useful when making animatics to test the direction characters walk across the screen)
added IMB_flipy was alredy there, needed to add IMB_flipx.
|
|
This adds "[#6766] Transform Sequencer effect" by damiles.
* Configurable interpolation: no, linear, bicubic
* Makes it possible to specify coordinates in units of pixels or by percent
of the picture size
It makes the code a lot more clean, since new imbuf functions are used.
This patch also fixes
[#6829] Limit on VSE Transform Effect

Major sequencer rewrite to add Speed Control effect.
Changes:
- Cleaned up large parts of sequence.c removing a lot of unnecessary code.
(We first built old seqar array to decide, what is visible, then build
dependencies with new code, then used old code to iterate through the
strips and deciding using new code what is used and so forth and so on...)
Should be much faster now.
- Now we build the strips recursively thereby elemenating the need of a
seperate dependency calculation.
- Added a Speed-Control effect to change strip speed afterwards.
(Offers global speed as well as IPO-controlled speed.
There are several modes to play with:
- Control by velocity (IPO = velocity where 1.0 is normal speed)
- Control by frame number (IPO = target frame)
- IPO-Value can be rescaled to frame-value, to make frame exact matching
possible. (Matching video tracks to audio tracks with IPOs ;-)
Demo-Blend file is here http://peter.schlaile.de/blender/sequencer/speedcontroltest.blend
Since this was also a Plumiferos request I hope to be mentioned in the
credits ;-)
Enjoy! And please test the new sequencer thoroughly. It is really more like
a rewrite this time.

This adds support for "generator effect strips", which don't need necessarily
an input strip and my version of Matt Ebb's [ #5035 ] 'Solid Color'
sequence strip.
TODO: With a little bit more tweaking it will be possible to make animated
effect plugins and my still unfinished "Bake"-Strip.
For the 'Solid Color'-Effect, to quote Matt:
This is nice and simple, just provides a solid colour that's set in a colour picker in the properties popup. This is something we've needed for a long time, and I got totally sick of having to make 'black.png' and 'white.png' just to do fades, so I coded this.

Added enhancements by blendix (Patch #4919: Insert sequence effect between)
It adds the following things:
- You can add a sequence strip afterwards in the middle of an effect chain
(you have to move strips around before, so that there is "room" for it.
Blender will ask you then, if you want to add in between or after the
selected strips)
- In the case you messed it up and want your effect strips to be reassigned in
a different way, there is the new "R"-key. Just select three arbitrary
strips and press "R". If you don't create a cycle, those will be connected
to a new effect chain.
- Fixed freeing of imbufs on changes to properly take into account dependencies. An example of a simple case that went wrong is one image strip with two
glow effects, changing the parameters of the first glow strip will not
result in any updates. Basically only direct dependencies were taken into
account, which resulted in the image preview not being updated in some cases.
- Let the sequencer detect an active sequence strip if none is defined, to
get rid of annoying error messages when trying to add an effect to a
selected sequence strip right after loading a file.
- Delete is less destructive. If you delete somewhere between other strips,
Blender now tries to relink in a reasonable way.
- The active sequence strip is now displayed with a light instead of a dark
outline, which makes it easier to spot, and is especially useful for the
tools using the active sequence strip.
- Ability to view the final result when editing inside meta strip.
The channel button was modified to also allow negative numbers,
where -n is n levels up the meta stack. There is probably a nicer way to
specify this, instead of (ab)using the channel button, but this seems to
work quite efficient.
- Also a small bugfix: don't crash on loading files from newer versions with
an unknown effect strip.

Bugfixes: Fixed partially bug #5030
Added patch: #4992 Basic Transforms
This adds basic transform capabilities (rotate, scale, shift) to the
sequencer.
|
|
This patch is mostly a usability patch for the sequencer, mainly written by
Anders Gudmundson and twisted a little bit by me.
- Lock Time to other windows
- Possibility to switch the X-Axis between frames and seconds-display
- IPO-Frame Locking for plugins (T-Key)
- Additional Popup to add HD-Sound and Movie at once
- In Timeline-Window: Sequencer windows only playback
- Make the IPOs a little bit IPO-Frame-Lock friendlier (doesn't jump;
the frame that is drawn has the right dimension)
- Wheel-Mouse buttons make the sequencer window zoom again.
- The "This is not a sound/movie-file message" now reads "... or
FFMPEG-support not compiled in!" since I learned some prominent
people who complained, that hdaudio does not work for them ;-)
- Make SPACEKEY open up the "Add Strip"-Popup on the timeline and start
playback in the preview window.
|
|
- blur works again (this was a serious bug in gamwarp...)
- seperates all sequence effects into a seperate file with a clean interface
- thereby fixing some obscure segfaults
- seperates the scope views into a seperate file
- adds float support to all effects and scope views
- removes a bad level call to open_plugin_seq
- FFMPEG seeking improved a lot.
- FFMPEG compiles with debian sarge version cleanly
- Makes hdaudio seek and resample code really work
|
|
* Boosts the blender frame limit by changing the type of the frame number
from short to int everywhere. Without this, timelines longer than a few
minutes are impossible to handle.
* Adds several types for ffmpeg input/output, hdaudio-tracks in sequencer
|
|
a strobe effect synced exactly to a beat, for example, by using non-integer
values.
Is it just me, or are there recently a lot of crashes in sequencer when
using audio strips?
|
|
In the NKEY flying panel, you can set "Strobe" to something other than 1
for only displaying each nth picture of the strip. You know the effect
from movies :)
(I put this into the NKEY panel rather than as a effect because effects
only affect single frames (?) while this rather has to do with the
timing... like "Reverse")
|
|
Option to play sequence strips (Movie, Image, Scene) in reverse.
New toggle in the NKEY buttons for sequence strips.
Thanks Shaul!
|

File name (40) and dirname (80) were too short in sequence data. Made it
compliant using defines FILE_MAXFILE and FILE_MAXDIR.
Also replaced all strcpy() and strcat() with strncpy/strncat, with the
defines in it.
Oh, also fixed plugin path length for sequence, was just 80!
Bug fix #2366
Restored old convention that made using SHIFT+CTRL while using button-
sliders go with 0.1 stepsize of CTRL.
(noticed too late that Chris Burt assigned to self... sorry!)

When using Sequencer for Alpha-Over images, it was assuming "Key" alpha by
default, and converting images to "Premul" (= multiplying RGB with alpha).
This isn't very nice, also because alpha generated by MBlur in Blender
always is of type Premul already.
Solution; make this an option. In the Nkey panel for strips you can set
or disable Premul now. As extra also added the "Filter" and "Mul" options,
as already there for Movie strips. Can easily be extended to more options
for various postprocess effects.
|
|
This was actually a wrong pointer check in fileread that caused no harm
in past, but with UI-less file save it wreaked havoc!
Decided to add undo in sequencer window after all... it also involved
saving Meta strip settings in files. Very nice :)
|
|
Found error in wipe struct, which was even constructed terrible weird :)
|
|
backend variable naming.
|
|
committed that was originally a sequence plugin from sirdude.
The changes from the original include the ability to add a blurred edge with a selectable width to the wipe and to rotate the effect.
Has these sweep types included already
-single
-double
-iris
These still need to be coded
-box
-cross
-clock
|
|
|
|
Ton, where would I be without you)
- Sweep effect updates after you change the type of sweep now.
|
|
this consists of 22 different ways to sweep from 1 strip to another. For you windows lovers: it's like "Blinds" in Powerpoint :)
- in the NKEY menu you can choose which type you want perform, vertical, horizontal, in/out etc. it's too much to decribe.
Credits for this go to Kent 'Sirdude" Mein who coded the sequence plugin I stole the code from.
To allow certain sequence effects to have settings, I also added a "varstr" void pointer to the Sequence DNA, that can point to a special struct for each effect. This is similar to how plugins are handles.
more neat effects to come....

size of this;
Finally, the Sequencer audio support and global audio/animation sync stuff!
(See http://intrr.org/blender/audiosequencer.html)
Stuff that has been done:
./source/blender/blenloader/intern/writefile.c
./source/blender/blenloader/intern/readfile.c
Added code to make it handle sounds used by audio strips, and to convert
Scene data from older (<2.28) versions to init Scene global audio settings
(Scene->audio) to defaults.
./source/blender/include/BSE_seqaudio.h
./source/blender/src/seqaudio.c
The main audio routines that start/stop/scrub the audio stream at
a certain frame position, provide the frame reference for the current
stream position, mix the audio, convert the audio, mixdown the audio
into a file.
./source/blender/makesdna/DNA_sound_types.h
Introduced new variables in the bSound struct to accomodate the sample
data after converted to the scene's global mixing format (stream, streamlen).
Also added a new flag SOUND_FLAGS_SEQUENCE that gets set if the Sound
belongs to a sequence strip.
./source/blender/makesdna/DNA_scene_types.h
Added AudioData struct, which holds scene-global audio settings.
./source/blender/makesdna/DNA_sequence_types.h
Added support for audio strips. Some variables to hold Panning/Attenuation
information, position information, reference to the sample, and some flags.
./source/blender/makesdna/DNA_userdef_types.h
./source/blender/src/usiblender.c
Added a "Mixing buffer size" userpref. Made the versions stuff initialize
it to a default for versions <2.28.
./source/blender/makesdna/DNA_space_types.h
./source/blender/src/filesel.c
Added a Cyan dot to .WAV files. Any other suggestions on a better color? :)
./source/blender/src/editsound.c
Changes (fixes) to the WAV file loader, re-enabled some gameengine code that
is needed for dealing with bSounds and bSamples.
./source/blender/src/editipo.c
./source/blender/src/drawseq.c
./source/blender/src/editnla.c
./source/blender/src/space.c
./source/blender/src/drawview.c
./source/blender/src/renderwin.c
./source/blender/src/headerbuttons.c
- Created two different wrappers for update_for_newframe(), one which scrubs
the audio, one which doesn't.
- Replaced some of the occurences of update_for_newframe() with
update_for_newframe_muted(), which doesn't scrub the audio.
- In drawview.c: Changed the synchronization scheme to get the current audio
position from the audio engine, and use that as a reference for setting
CFRA. Implements a/v sync and framedrop.
- In editipo.c: Changed handling of Fac IPOs to be usable for audio strips as
volume envelopes.
- In space.c: Added the mixing buffer size Userpref, enabled audio scrubbing
(update_for_newframe()) for moving the sequence editor framebar.
./source/blender/src/editseq.c
Added support for audio strips and a default directory for WAV files which
gets saved from the last Shift-A operation.
./source/blender/src/buttons.c
Added Scene-global audio sequencer settings in Sound buttons.
./source/blender/src/sequence.c
Various stuff that deals with handling audio strips differently than
usual strips.
