How do I make the Video Sequence Editor (VSE) playback in real time? I have some 4K video clips that I want to edit, however, I'm unable to do so because when I hit play I get about 2 FPS playback (even without any effects/Modifiers applied) instead of the video clips/timelines 25 FPS. I have a pretty powerful computer, and these clips have no problem playing back in, for example, Premiere. I know Blender's VSE isn't the best or most powerful, but there's gotta be a way to playback the video and audio clips you edit in real time?

I a lot of VFX breakdown that uses something they call "render passes". From what I see, they are rendering the clip in seperate ways (like rendering the ambient occlusion, specular, shadows, depth of field, etc individually and then combine it). Is there any way I can do this?

When creating a video from an image sequence using ffmpeg, I'm finding that I get a same length video whether encoding it as 30fps or 60fps. Given, in my current case, 6329 image files, the following two commands produce video files of the same length:  1. ffmpeg -pattern_type glob -i '*.png' -r 30 -pix_fmt yuv420p out-30fps.mp4 2. ffmpeg -pattern_type glob -i '*.png' -r 60 -pix_fmt yuv420p out-60fps.mp4   With the above, ffprobe shows video 1 is 00:04:13.17 and encoded at 30fps, while video 2 is 00:04:13.15 and encoded at 60fps. When loaded into Quicktime Player, both videos have the same length and speed.  So, two questions:   I'm confused by the total video duration, as 4m13s is a total of 253 seconds. At 30fps, 253 seconds should require 7590 frames, not 6329. What is required to use the existing frame sequence as if it's 60fps source instead of 30? Or, put another way, how to make the final video have twice as many frames/second during playback?

I can't find the option that supposedly existed in Blender 2.49: "Enable Frame Blending". Does anyone know where it is, or where is its analog?  I shot a sunset - 30 minute video I want to turn to 10 second sped-up video. I easily do that with Add->Effect Strip->Speed Control, and setting  to 200.   This drops 199 frames out of 200, which isn't quite what I'm after.  There are people walking in front of the camera. I want to blur every 200 frames into 1, so that there are blurred trails of people rather than snippets of people.     Google says that all I need to do is check the "Enable Frame Blending" option. However, I cannot find this option in Blender 2.74 UI or source code, so it probably got renamed. Does anyone know how to fix this? I cannot use Blender 2.49 (I tried.. The new blender UI is tough for me to get around, googling basic things 20 minutes at a time; the old blender is however just an impenetrable wall of foreign UI concepts)

I'm having trouble finding a cli application that can take a video file (avi, mkv, and mp4 preferably) and cut out very short clips (2-6 seconds) with precision time accuracy. I've tried ffmpeg, mencoder, avidemux, and mp4box but they all cut on keyframes which creates 6+ second clips. Is there a tool that will re-encode the input file and cut the accurate time or cut inaccurately, re-encode, and then cut accurately?

Any idea of why my viewport preview of the simulation stops at 250 frames? (as you can see on the orange line on the timeline)  Am I maybe missing any kind of configuration?..  It's a rigid body simulation.. e.thing works fine but the preview freezes at 250 frames.... No keyframes on the simulation, only on the colliding object that has an infinite loop rotation.....    Is it maybe because of motion paths setting?  It is set on 300......       Update:  Problem solved! I missed this tab of configurations!!

I have a pre-rendered animation that I want to play on a TV model in my new scene animation, and I really don't know how.   Would I do it within Blender, or should I make the material on the TV screen green, so I can green-screen it on?

I am trying to render a video (that is not a .dvd file) with audio using Blender. So far, I haven't had any success; all of my rendered clips have had the audio missing from the playback. I've tried a couple of different encoding and output options but nothing has worked so far (except for a .dvd file that I rendered originally).  What are my options for rendering a video with working audio?

What I know about blender's V.S.E. is that it can cache a certain amount of frames before dropping frames(). But, on my Ipod I have video editors like Imovie, and Cute Cut and there is never a delay with the videos, even with different FPS. (maybe because Cute Cut and Imovie have a ?) So what method do they use, or does Blender just use an out-dated version of Caching? Also my Ipod has much smaller RAM so it wouldn't be able to Cache much. Then when I'm finally done making a video why do  have to I render it? With other Video editors, like lightworks or Filmora or Imovie or CuteCut or WindowsMovie maker or pretty much everything else, I export it. So is Blender's VSE outdated- or the opposite, it's so good that normal pc's can't handle it? Which begs the question, why not have a dumbed down version for normal pcs?   Wow, ok that's a lot a questions, sorry, but to narrow it down to one(two) question(s):  How does Blenders VSE work, what makes it so slow?

I've made a simple animation in blender 2.81a and am now trying to render it.    My system specs: CPU i7-6500U; GPU Nvidia Geforce GTX 950M; RAM 16gb DDR4 So far, I've done two test renders (both in cycles):   8 samples, 8 light bounces, denoising on, 60fps (240 frames). Total render time was about 3 hours. Looking at single frames, they were flawless, but if you play the animation, you see that the denoiser is producing some kind of jitter (like in ). 256 samples, 4 light bounces, denoising on. I set the framerate to 24fps and used time remapping to maintain animation speed (96 frames). The jitter has become far less, but is still there. However, the time remapping made the animation look kind of not-fluent. So I figured that I probably need 512 samples to reduce the jitter and render at 60fps. However, this will probably take about 16 hours to render. Are there any other ways to   change the framerate without changing the animation speed? (except for manually repositioning keyframes) decrease general render time/reduce the jitter (aka denoising for animations) Thanks in advance!     Edit: I heard that Blender 2.83 and 2.90 (which is not yet oficially released) have improved the denoising system, e.g. AI-accellerated denoise, adaptive sampling and optix viewport denoising. Do any of these also apply to video or is there now any option for better denoising for animations?

I have been struggling with .mp4's for about 2 days now, trying to concatenate a series of about 20 into 1 single file. Any differences between the files and it is a nightmare. Some files have different fps, and others different ratios.  I wanted to know if mp4 is the format I should be using, or if there is a better, easy to use format for concatenation. Time isn't an issue, I simply need a relatively high-quality format that concatenates under most circumstances.  If this doesn't exist, any suggestions on how to deal with massively varying properties of mp4 files (I'm not entirely sure of what can differ aside from fps and ratio between videos that may cause a problem) would be great.  I am using ffmpeg to try and concatenate the files. First I tried to use the demuxer, and then the concat filter, however I find the concat filter very daunting and am completely at a loss as to how to use it.  Each video has audio, some have still images while others have moving.

Is there a simple way to log/save every render that you make in a Blender scene? Maybe an add-on? This would be helpful to visually see progress on modeling, materials, lighting, and whatnot. It would also be helpful if it could "print on" the date/time, vertex count, and the camera settings. Am I just dreaming or is there a way to do this?

I am using Blender's Video Sequence Editor and it won't let me render it. The error message...     Timebase 20999/500000 not supported by MPEG 4 standard, the maximum admitted value for the Timebase denominator is 65535   ...keeps popping up. I don't know what to do. It also won't let me save it either. Here are some screenshots.

Whenever I render a video using the blender video editor only one core is ever used at any time. I have an 8 core CPU(FX-9590) yet regardless of whether blender is set to auto detect or a fixed 8 threads only one core ever sits at 100% at any given time. The rest of the cores sit and really low usage as if blender is completely ignoring them. I'm running blender 2.77a on Linux. I'm using Theora as the codec with an ogg container and Vorbis audio. How do I get blender to use all my cores?

I am currently using Sheep It! to render my blend (built on v2.68c) on multiple computers, and I noticed something rather strange. According to the log on-site, the frames rendered from other people's blends were completing in 3 to 4 minutes. This was on an 4 core i5. My main rig (with an 8 core i7) was completing frames in no less than half an hour. How is this possible?  To clarify, these people's frames are very complex, often with very detailed textures. I have 2 objects in my blend. Below are the options I changed for my blend:   Aspect Ratio: 1000px x 1000px Output: PNG Clamp Indirect: 0.98 Render Sampling: 128 Min Light Bounces: 0 Max Light Bounces: 4 Cycles Render   Is there something in there that I should change to make it go faster? I can't really comprehend how it's going to quickly.  EDIT: To answer what @Duarte asked...   System Specs: i7-920, 3GB DDR3, GT 630, Windows 10 I have two circles, extended to form a sort of coin with a star on it. It is not complex at all. I have Firefox and Steam running in the background, but not actively. I've been away from the computer for 8 hours and noticed this behavior. (I am running Blender from Steam.) I made sure when I began rendering that the blend was set for CPU rendering.          And to answer what @pycoder asked, yes, I am using Cycles Render.

Is there a way to let embedded videos (primarily Flash, but I'd prefer something that will also work with HTML5 video) automatically background load, but not start playing until explicitly started?  The typical use case where I want this ability is when opening a number of what I expected to be text pages in separate tabs using middle-clicks only to have something start yapping at me; at which point I need to click through all the new tabs to find and stop the offender.  I'd prefer not to completely block video download to avoid the startup delay if I decide to watch the video when I view the page its embedded in.

I am having a problem while playing .mkv files. Every time I play a .mkv file, the audio can be heard but video cannot be seen. The only way to see the video if I actually right click on it or put a window in front of it and it displays one part of the video but not all.    The link of the picture above basically describes what I am saying. While I was trying to take the screenshot, the window for the screenshot disappeared and displayed part of the video. I hope someone could help me on this. Thank you!   EDIT: I was running Unity 2D when I have the problem but when I run Unity 3D, it works. So I need to make this work on 2D. Please help.
