Developer sneak peek #26 – Video Sequence Editor (Blender 2.77)


hello and welcome to a new planet develop a sneak peek i’m your host Thomas Beck and the emphasis this time is on all the awesome new features for the sequence editor in the suit to be released glenda version 2.77 the test builds are out so please download and test it if you’d like to support me and make sure that more videos are created more frequently then use the Amazon link in the video description to buy my German blender book or by other stuff from Amazon with the link but now I wish you a lot of joy with you following sneak peek so first stop it the Gaussian blur effects has been incredibly speed ified the effect has been applied here already this is the image and that is the effect you can edit via effects rip and then Gaussian blur and it has only two options the size x and d sighs why and when we now enter for example 5 pixel at five pixel or then you can see that it’s pretty fast any 2.76 and that let it let’s increase that to 10 then you can see it’s lasting a bit longer and 20 will last even longer see it’s calculating and calculating and now it’s there let’s now test that in the 2.77 release first with 5 and immediately an immediate result and then with 20 and again an immediate result so as you can see it has really an incredible speed up 50 even 100 should be no problem at all so that’s it for the Gaussian blur effect next is the white balance modifier and this is modified that I created why I was editing videos for Christmas as you can see here and therefore I just cut out one frame and this frame shows pretty much all that you modifier does let’s just edit by hitting at strip modifier white balance and then let’s choose the value that should be white in the image later on and I define this value as to be white and as you can see now the complete image is now altered that this value is the new white point and that is all the modifier does it is meant for video but it can be also used on images as you can see here and yeah that’s my present for blender for this release next on our list is the tone map modifier and the atonement modifier was already available in the compositor and it’s meant for tone mapping who would have thought that and tone mapping is the process of mapping one value range into another value range and in this specific case it’s for meant 4-h ers because HD RS are ranging from minus infinity to plus infinity almost and those values that can’t be displayed properly on your monitor on you on your display device like a monitor are shown overexposed overexposed or completely black as you can see here that’s completely overexposed but when I now add an toan map modifier like I’ve done here and enable it then you can see immediately that those values are not indeed overexposed they were just not displayable by your monitor and by enabling those mapping techniques that are defined by arch rh simple or rd photoreceptor you can then transform those values into values that your monitor can actually display let’s continue with the text effect and the text effect was introduced in the last release I think you should just look at the sneak peeks then you would see you when it’s even what it was introduced and it’s under effect strip and then text and as you can see here there is this text at strip input word it’s under if extra if you select it then there is this text with a certain size that you can change and all those locations things there but there’s a new new property as well and it is rep with and this property defines how wide you text ISM is going max and if you for example say it’s zero point 20 that’s twenty percent of the image dimension then you see that the texts are Road wrapped before we’re coming to the minor additions let’s just see one last thing that is in effect when you combine Reese pencil or seen scripts with other strips in the VSA and let’s just hide this one so you see which script strip is beneath its this one and when I now unhide it then you can see that there is a grease pencil layer available in this scene let’s just switch to this scene by going to default then you see the scene as us what switched automatically and you can see that i wrote down this is a grease pencil test and when we now switch back to the video editing then you see even when i set this strip here to alpha over like I’ve done here you can’t see the underlying strip and that is because this this gray background here is the rigid switch back is the background in this scene and now with blender 2.77 there is the option to enable this alpha mode transparent here and if you enable that then it gets it that it that it is taken into account when we create the scene and let’s just refresh it by clicking and then you see it it’s now working perfectly this is a trick Chris pencil test over the background and when you render it via this OpenGL render button then you see it’s working let’s now come to the tiny bits that has been changed in the vse but they are nevertheless very cool the first one is the mask relative and absolute time and that is here the let me just introduce the curve modifier and then go to masks so now we got a relative and absolute here that wasn’t there before and that is doing the following if you select the mask here some masks that I drew around those around those mushrooms I hope they are called mushrooms and when you now animate this mask then this mask animation is dependent on the scene frame on the scene time for in general but when you have it as in relative then it’s offset to the start of the script of the strip of this strip so that is completely different and makes animating a mask and using this animation in different manners for example to darken edges or juice to color correct certain parts of the image really possible at first that is the the relative and absolute and then there is the apply modifiers or replacement append modifies or replace modifiers so if you got an modifier down there for example the white balance modifier and you’d like to have this modifier that is available there appended to this one then you would just say I select this one and this and go to copy to select those ribs and then you can choose replace or a pent and in our case we would choose append and now this this trip has both modifiers applied the white balance and D curves and formal formerly it was only possible to replace them another really nice feature is the automatic frame rate changing when you import an movie strip and we can simply test that look at this frame rate it’s 25 frames per second when you now import a movie for example the documentation about the life of pi then you see that it’s changed accordingly to the movie French per second that is the twenty three point nine eight frames per seconds and when other strips are in the project then it would be changed so don’t be afraid that anything is going wrong if you import a new movie script from now on but it’s very helpful to set it up first if you import it and then it gets changed automatically another really nice thing has been transferred from the gooseberry branch in the last weeks and it is seen meter strips and to show you what that does if you change the scene to this prepared strip scene and in this scene I’ve got four or five strips and those strips are just lying there and what we know what we are now doing is we change this trip to dirty to see into the vs DC and import the scene where those strips are located so just go to scene and strips scene when we now look at this scene then you see there is no strip showing up here but that’s only because you didn’t notice this new checkbox here at you sequence when you take that then there’s those strips as you can see here in a lighter gray are shown down there and up there so what you can do now is have more or less a scene file where you organize your strips several seen fights where you organize your strips and then import those strips into the vs e and have them edited all together so it’s a kind of a meter script design in blender now and this concludes the developers need peak already I hope that you had fun watching and learning new stuff and I hope to see you on my Google+ YouTube and Twitter page please share it to make the new features well known and now happy planning bye

  • Fantastic and Thank you for all your hard work, although I'm just starting out in Blender and won't be ready to use such neat tools just yet. I appreciate all you Developers that work so hard to improve Blender for me and the rest of the World.

  • Great stuff! Thanks for the video! Is there an official place for suggestions or conversations about what would be nice to see? Or even just to see what's upcoming (regarding the VSE) from the developers?

  • Thank you for this. I think the biggest problem with VSE right now for some of my projects is when it do not handle variable bitrate and different FPS from strips appended to the editor. Is there any solution to that?
    Importing different movies leads to their different lengths and AV is no longer in sync for some of them. Is there ONLY a speed control stripe for this, or I miss something?

  • dude you should totally make a video on the new Boolean tool integrated in edit mode, I'd love to see a modelling update!

  • I love how the VSE keeps getting sexier and sexier, it's feeding the constant conflict of deciding to use Premiere or blender at any given moment. My favs in this update:

    – Auto-setting the frame rate. YES. Finally. Would be nice if it auto-setup the reoslution too, I'd love to not have to keep using a little script I put together because I have to do that all the time.
    – Copy modifiers (append vs. replace). Awesome, this is such a critical thing for video editors when actually making use of modifiers/effects.
    – Geace pencil update. Haven't experimented yet, but sounds like it could now really one-up photoshop's frame by frame animation often used for music videos. Not that we couldn't already do that with blender in the viewport, but having it integrated with video editor is awesome. Next step, being able to draw the pencil layers into the scene from the VSE 😉
    – My favorite by far: Node compositing modifier! jk this doesn't exist yet 🙂 Think I've commented about this before, I would loove to have a one-button setup that replaces a selected strip with a new scene pre-populated with a node seutp using the starting strip input image/video – which you can then just jump into that scene to do the advanced node editing. Would be amazing if this could somehow be applied as a modifier in addition to other modifiers to other strips, e.g. if doing a more advanced color grading you want applied to multiple strips but want to keep other modifiers etc.

    Side note on the later feature of using strips / sequences from other scenes: Awesome, I really like that – and if there was an option to double click to auto-open the other scene and bring up the VSE there, I would find it even more useful than nesting strips I think. This is much more like the "pre-comp" feel one gets with after effects. This also makes re-producing common sequences crazy easier, e.g. video outros because now we can append pre-setup scenes into a new project and just link in the strip.

  • Fantastic! Thanks for your work!
    One quick question that maybe you can help me with:
    Do you know why Audio Samplerate and Channel Count rendering options aren't in the "Render Properties Tab"? It's in the Scene Properties Tab. I would love to see this option under the Audio Codec in a future release. I was teaching blender for over a year before I realized that one could change the sample rate in the Scene properties tab.

  • use sequence is a useful addition, thanks for pointing it out. quick question, is the gaussian blur speedup due to OpenCL or another API?

  • TYVM for the WB modifier; it doesn't only look great in Blender, it also makes up for the deficiencies in my old cameras.

  • Just want to thanks everyone who is participating on Blender development – it is such a great piece of SW and for free! Thank you again!

  • Please please please, add an ability to set text font into Text strip in VSE. It is so basic functionality and I find it very frustrating to prepare my texts in image editors 🙁 VSE is excellent otherwise. Thank you!
