I'm recording with OBS. In OBS, I have two options for audio recording, Desktop Audio and Mic Audio. Each of these are mixed together and saved in the same MP4 with the video which is recorded.  When I open the .mp4 in Blender, both the Desktop and Mic audio have are in the same audio strip.  How do I separate audio sources and import them for individual editing?  I'd like to have game audio, microphone audio, desktop audio (game?), and other programs (Discord, in my case) all as separate audio strips when I pull it into Blender.  Any ideas as to how I can accomplish this?  EDIT: I should add that I've tried sending video to OBS via Dxtory. I've also tried simply recording with Dxtory only, but I do not seem to be able to record separate audio clips for use in Blender.

I've recently started using OBS multiplatform to record game play. I currently have it set to record sounds on 2 different tracks. The first for system sounds (like gamesound, mumble, etc.) and the second to record the mic.  I am able to switch between tracks when I play the unedited video using VLC, but when I load the mp4 into blender, I only get track 1.  Did I do something wrong, or does blender vse not support multiple tracks?  Blender after loading mp4:  VLC video information:   UPDATE  For now, it seems like the solution will be to use an external tool to get the second audio track and import it into blender afterwards. A  has been logged with the Blender bug reporting tool.  UPDATE 2  The bug report has been closed/archived with the gist being "not a bug". It has been added to the . If you are looking to have support for multiple audio tracks, I would suggest looking at other video editing software until Blender adds support for this feature.

I want to merge an audio file (.wav or .au format) with a video file (.mp4 format).  Please suggest me how to achieve this. I want to merge these file to new .mp4 video file. An ffmpeg command would be very welcome.

I started using Blender couple of weeks ago to edit some of my video clips. Spent quite a while editing this one, and everything worked fine. Video rendered as it should. The whole project consists of a MP4 file with a whole lot of soft cuts. Came back to it a couple days later and now the preview won't show a thing. When I render the scene, it's just a black screen with no sound.  The original file is still working, as well as my other Blender projects. And the weirdest thing is that if I add a new movie clip to the project, the preview works just fine for that clip.  Can anyone guess what might have caused this? I've googled like crazy and haven't found anything helpful.

I am setting up a Lubuntu box to install in a local classroom where people are not super tech-savvy.  I need an audio recording application for them to record things using the microphone and save in a specific folder. I have chosen Sound Recorder because Audio Recorder and Audacity are too complicated.  I have one problem; the only option in the Record From field is Master and the Record As field where there should be file format options (.ogg, .wav, etc.) is blank with no options.  Can anybody tell me how to actually record sound using "Sound Recorder"?  when run from terminal, when I press the record button it shows:  (gnome-sound-recorder:1894): GStreamer-WARNING **: Element 'gconfaudiosource' already has parent

Got a bunch of .mp4 videos (info shows H.264 Video + AAC Audio) that are chapters of a larger video.  I'd like to merge them, but not sure which is the best way.  I don't have Quicktime Pro, but I'll get it if that's the best way to do this.  Edit: Just to clariify this is Mac OSX 10.6 I'm on.

I'm using Blender 2.77.  When I import footage into the VSE with the correct frame rate (23.98fps) every single audio strip is 2 frames longer than the corresponding video clip.  I think the problem is that my recordings are actually 23.97fps.  The issue with that is that when using the custom fps setting there are not enough decimal places to input a value that will result in a frame rate of 23.97 (i.e. 1.0015).  I'm not positive this will fix it but I think it should.  Does anyone else have any ideas or experience with this issue?

I just installed Blender 2.8 and for the life of me I can not find AV Sync anywhere and video editing has become impossible. Is there some new setting I am unaware of?

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.

I tried to add a 3D object to a clip by following a youtube video. But clip doesn't show up in the render or in the compositing tab. It show up even in the camera view. I didn't change any settings. please help. Thank you.    And the  rendered images has only the cube in it like in the picture above.

I'm trying to record both what's happening on screen and the audio being played by the applications. To my surprise, QuickTime did not record the sound. I believe it worked before in previous OS X releases, but that is not something that I use often so I have not bothered to try earlier.  What is the current situation on El Capitan ? Have I messed with something that prevents QuickTime from capturing the sound, or has it never worked ?  Here is my view of Quick Time  / New Screen Recording on a Mac Mini:   On my Macbook Pro, I have the option select None or Internal Microphone. Internal microphone actually records the speakers of the Mac Book as heard from its own microphone, which obviously sounds terrible.  This is a MacMini 7,1 (late 2014) and there is nothing in Input Sources.

My scene uses multiple render layers.  I'd like to edit each rendered layer in Photoshop, and composite it in Photoshop.  Is there a way to export each layer as an individual image?

I have some apps that I want to record the output sounds locally before outputting to speaker, Bluetooth or any other output. So I get clean unadulterated audio, before any audio output mods.  My devices are rooted, some have custom ROMs.   Is there a way to do this internally, without any programming/coding knowledge? Can this be accomplished? Preferably with out hooking to PC as that prevents local saving.   include steps.  include references      Please excuse lack of tags, limited on choices.

I am using Ubuntu 15.04 and Blender 2.72b.  I've got a video clip where I want to display some annotation-like text next to some potatoes on a white table. The potatoes move a little in the video so I would need to adjust the text a bit every few frames.  (I am a total beginner, I have not used Blender's clip editor before.)  How would I attach text to a tracked point (to the potato) and manually adjust the text's location when required?

this is my first question and I am very much a beginner in electronics so I apologize if this is a too stupid question.  I have Atari punk console and another small homemade audiomaking circuit. These two have mono audio signals as outputs and I would like to combine these as one in the simplest possible way. I know next to nothing about audio processing but I believe that the strength of the two signals is roughly the same.  What would a neat solution be? It would be really nice if I could extend the solution later on to more than just two signals but thats not really important.  Any hints, references, guides, links or ideas would be highly appreciated.

I've tried using VAC virtual audio cable, as well as virtual audio streaming. Unfortunately, none of these solutions provide a way to send audio output to a microphone input. None of the virtual audio cable related posts on here or internets address this specific limitation.   The reason I want to do this is to stream audio to the microphone and set the microphone as input device for another program. This "other program" only allows microphone inputs to be used as its input device.  See how no mic's are listed as output devices:    There is a software called Solicall which actually allows this. But I would like to do this through VAC virtual audio cables because Solicall only allows one instance running. Thus, I can't do my audio routing method more than once simultaneously. I have yet to find a better solution however than Solicall.  Someone please post if you found a way to do this with virtual audio cables, or any solution more elegant than Solicall. Currently, all the virtual audio cable programs I've tried do not allow microphones (real or virtual) to be selected as output.

I'm making a PC Horror game in Unity, and I want to have a camera recording simulation in-game - so you can leave a creepy location anytime, and you will have a tape with what you recorded on camera while exploring. Technically, I need to attach a second camera (hand-cam) to the character's hand, and let the player look through the viewfinder by pushing a button. But in any position, the hand-cam must record everything that is in its focus at that point - floor, stairs, rubbish, etc, whether it's lowered at hand level or raised to match the player's viewpoint. When the game ends (player leaves or dies), I'd like to have an option to save recorded tapes to a video file (if this is not possible, then to some save file). How can I implement such a feature in my game? Are there some special Unity tricks, or add-ons and additional modules? Saving decorations and scenes with active triggers, or just grabbing video from screen? Below is a quick MSPaint concept of what I mean:

I used to record iOS devices through QuickTime, however now it's only recording audio (not sure is this linked to OS X 10.11 or iOS 9).  How can I fix this (without third party sofrware)?
