Put that value in the box at the bottom of the window where it says 250: Enable AV-syncĪlso at the bottom of the window is a control to enable AV-sync. Looking in the properties to the right of the audio or video strip you can see the actual number of frames. Right click the audio strip to highlight it and then go to the properties on the right hand side and click to show the waveform: Rendering lengthīy default, Blender assumes you want to render 250 frames of output. Use the context menu to change the properties panel back to the strip view panel:Īnd then right click the video strip (the lower strip) to highlight it and then add a transform strip: Audio waveform When you want to generate the output file, come back to this panel and use the Animation button at the top. Now your basic rendering properties are set. Specify the directory where the files will be placed and use the # placeholder to specify the number of digits to use to embed the frame number in the filename:
Later we will combine them into a WebM file with a script. Also check that the resolution_percentage setting under the picture dimensions is 100%: The input file is 25fps so we need to use exactly the same frame rate for the output, otherwise you will either observe the video going at the wrong speed or there will be a conversion that is CPU intensive and degrades the quality.
#BLENDER VIDEO EDITING CHANGE FRAME RATE 720P#
The video file we are playing with is 720p, so it seems reasonable to use 720p for the output too. Now you should see all the video sequence editor controls: Setup the properties for your projectĬlick the context menu under the strip editor panel and change the panel to a Properties panel: Choose the video editing modeĬhoose the video sequence editor from the pull down menu at the top of the window: Setting it too high may take memory from other applications and lead to swapping. Setting it too low may slow down some operations in Blender. Set it to a value slightly less than the amount of physical RAM in the workstation. This is a much better quality sound and we would like this to replace the sound included in the video file. A separate audio file with sound captured by a lapel microphone attached to the speaker's smartphone.A video file from a DSLR camera, including an audio stream from a microphone on the camera.

Here are some screenshots showing how to start editing a video of a talk from a conference. **Exact steps for others to reproduce the error**Quick start using Blender for video editingĪlthough it is mostly known for animation, Blender includes a non-linear video editing system that is available in all the current stable versions of Debian, Ubuntu and Fedora. Repeat process in 2.78 and notice that the correct framerate (30) is automatically detected, meaning this is a recent change in how blender handles frame rate detection.Īttached is a video that demonstrates the issue for testing purposes. Blender has set framerate to "Custom (1000.0)" with some other unfamiliar variables defined below. Add attached video file to VSE by any method.

mp4 files files produced by ffmpeg/blender seem to be fine, but mp4/mkv containers produced by OBS induce the issue.Įxact steps for others to reproduce the error Altering the framerate in the rendering panel only alters the duration of the audio. A 2 minute video has over 120,000 frames. Somehow, the video playback is still fine, but the number of frames is incorrect and zoom in the vse panel is limited. Videos which are correctly interpreted as being 30fps in 2.78 are being loaded in as 1000fps in 2.79. Worked: 2.78 and any previous version I've used for video editing, as far back as 2.5.
