I observed this behavior on Linux with Blender 2.83.5. I found a workaround: Create a font strip in VSE Set the font you would like to use (the preview does not reflect this) Delete the strip Perform an undo. At least in my configuration, the text is rendered in the correct font.

In order to get more control about the playback of an Image Sequence or Movie Clip, you can set the Frame property of the Image Texture node to the 'first frame' which allows to set the the 'current frame' based on the Offset property. If you'd like to reverse the playback of a Movie Clip or Image Sequence, you can add a driver expression to the Offset ...

Since all outputs and original video opened in QT and Blender is "desaturated" in the same way, I would say that it is more like wrong interpretation of colours in VLC. There is also noticeable contrast in VLC that totally flatten black parts (hairs) = loose all the rest of details that wasn't destroyed by camera and compression already. Original video and ...

Unfortunately, I believe this is 'normal'. It's 4k video, so it takes a lot to edit and needs a lot of optimization that is just not there yet. Make sure you update your video drivers because if they are not up to date that might cause issues, but I think it will lag some in any case. I would not consider using lower resolution preview a hack since that is ...

Here is a 2.8 theme from Blendswap Here is a 2.8 theme from Blenderartists.org Please keep in mind that Blender 2.8+ also has a new Collection system (instead of layers) - which can't be changed using a theme. Good luck :-)

You probably need to set a higher cache limit in your preferences. It is under the System tab. The default is 4 GB which may not be enough for what you're doing.

The answer is in your first paragraph Blender being painfully slow, almost unusable. Blender is a wonderful app to create 3d content, but is the video editing aspect is not adequate for today's needs. But the real problem lies in the way the video is encoded. Yes, the media info on the question shows a non standard frame rate (29.252). Most likely the video ...

It sounds indeed like a non-trivial solution, that will require you to get proficient with motion tracking and/or compositing. For a 3D way to do it you would need to track the footage and solve the camera. The success of the operation would depend entirely on the kind of motion from the cameras, if there is parallax on the scene then you might be able to ...

What you want is called Plane Tracking. The idea is that you associate 4 trackers to the vertices of a plane or an image. Track the elements and select Create Plane Track. In the compositor you use the tracking information to deform an image. For more detail read the following links: Can't choose Plane Track in Plane Track Deform node while compositing ...

If you want accuracy you should track the scene, solve the camera and reconstruct the camera moves and 3d environment. Watch the "match track blend" series of videos by Sebastian Keoenig to understand the process https://www.youtube.com/watch?v=U7AjIL_fDtU Then there is fspy (https://fspy.io/), a piece of software and a blender addon to estimate camera ...

No need to use afterFX for this. The idea is quite simple. You use green, or some color that is not present in the scene, to create a matte (or mask) that can be used to combine other elements in the scene. In the compositor connect the image that has the green element add a keying node, select the key color and the node will output Image and Matte ...

What you want to do is quite easy to do in blender with motion tracking. Open a new project as VFX File > New > VFX In the Clip Editor (not the Video Sequence Editor) open the video you want to use. Add a tracker on the face or whatever feature you want to track. Track the element. In the solve tab of the tools window, in the geometry section use &...

For future reference. Blender does support the H.265 HEVC equivalent made by google, WEBM/VP9 From VP9 Wikipedia: VP9 is an open and royalty-free video coding format developed by Google. VP9 is the successor to VP8 and competes mainly with MPEG's High Efficiency Video Coding (HEVC/H.265). At first, VP9 was mainly used on Google's video platform YouTube.The ...

Too bad you have spent all this time on something that blender is not good at. Here's the issue: the framerate reported is a non standard one (let me guess, the video file is a recording of some game or online video, or video from an android phone). Some software recorders put out a variable framerate to make the file smaller and not to choke the computer ...

It is a bug (any version newer than 2.83.4), This is fixed in 2.90 beta and 2.91 alpha. Thanks @vklidu for helping me out. developer.blender.org/T79952

You can't. Twixtor, and other apps that do slow motion, use a technology called Optical Flow that estimates motion vectors to create interpolation. There is no way, that I'm aware of, to do optical flow in blender. Blender has no temporal interpolation for video other than repeat or drop frames, or cross-fade (frame-blend) between two frames. None of those ...

No, blender will not automatically resize the image when you render at 50%. It will only render 50% percent of the pixels around the center of the image (Think of the percentage not as a resize, but as a crop). If you want to resize use a scale node, set it to render size and Fit, so that the image is rescaled using the output resolution.

You would have to split the strip using Shift+K, then ... just grab the right end of the left strip with your cursor and move it to the right. Then the last pic will be shown as long as you dragged the right edge.

to do it cyclic you can use this script: import bpy # define a driver function def driver_func(frame, maxframe): a = maxframe while a - frame < 0: a = a + maxframe return a - frame # assign to the driver namespace bpy.app.driver_namespace["bdriver"] = driver_func and then use this script as driver: Run ...

Go to View > Range then select Set Frame Range To Strips and it's done.

You are not in playing back at real speed. Go in the Timeline Window > Playback menu, and enable Frame Dropping option. It will respect the real speed but at the price of some frame droppings.

Importing .mov is not the issue. Mov files are quicktime files. Quicktime is a container that can hold video files in a variety of different compression codecs. Some codecs are more efficient than others. Some codecs require more from the CPU than others. Some require faster drives to sustain the data rate. Some are fast and easy to play at the expense of ...

I, too, am somewhat new to Blender, and this one has gotten me several times. If I'm guessing correctly, the problem lies in the order in which sources for rendering are processed. In the picture below, I show that the render output panel is selected in the properties window (upper left highlight). Way down at the bottom of that panel is a flippy triangle ...

Blender uses a fixed pipeline for rendering the VSE is part of this process. The movie clip editor let you track movies that can be used for modeling, compositing or sequence editing. Movie clip editor is an input for the rendering process. It is a common mistake people want to do this the other way around, but that isn't possible. Another analogy is the ...

In the video clip editor you can create masks and animate them with keyframes. For precise rotoscoping over video, load the video element on the Video Clip editor, create a new mask and you can animate the shape and feathering as you like. Overlaying an image to cover a face in a video? You can also use trackers and parent the points of the mask with the ...

Pink always mean that the image used is missing or cannot be displayed. If the frame you are trying to use does not exist in your video file you can instruct blender where to start the video file. as described in this link: How can I make a "Movie Clip" node start at a certain frame of the scene? use the frame, start frame and offset for the ...

Long story short. Until Vulkan is implemented in Blender (which is going to be soon from what I hear) you can use OpenCL Yes using OpenCL will reduce your render times significantly compared to when you have set it to 'None'. But since 570x is not that fast compared to 2600X CPU, it comes down to very specific situations where you will have advantage in ...

The problem is that you have a very powerful computer, but blender is not making use of it's resources. Blender video editor is quite outdated and does not take advantage of the hardware. Limited multithreading and hardly any use of the GPUs capabilities. Blender is wonderful for 3D content creation, but the Video Editing side of the program is not robust at ...

Actually, there are a couple of things you could test, if they will improve the performance. Try the Prefetch Frames(Cache) in the Preview Sidebar: Try the new Disk Cache, which may be fast enough if you point it to save on a SSD: Another thing to test is to make the project resolution(default 1920x1089) match your footage resolution(1080x1920), by ...

The Viewer and Composite nodes are different outputs, The Composite node is the one that is rendered out and saved to a file. The viewer is just to preview the result. Connect the composite so that it follows the same node path as the viewer, otherwise the images get processed following different transformations.
