Looks like ffmpeg needs to see the quotes around the parens, so you need to protect them from the shell with another layer of quotes. ffmpeg -i ~/Downloads/in.mov -vcodec copy -af "volume=enable='between(t,0,3)':volume=0" ~/Downloads/out2.mov Also, don't forget to specify something about the audio codec. ffmpeg's default AAC encoder is bad compared to ...

You can link multiple clips as you would link two clips. First, put all the audio and video tracks you want in your timeline and arrange them using the timecodes, manual adjustments or however you prefer to align the individual recordings (I'm assuming you have a method for that, since you removed that part of the question in the last edit). Then select all ...

If you want to mute the first 3 seconds of each audio stream then you have to filter each one: ffmpeg -i input.mov -filter_complex \ "[0:a:0]volume=enable='between(t,0,3)':volume=0[a0]; \ [0:a:0]volume=enable='between(t,0,3)':volume=0[a1]; \ [0:a:0]volume=enable='between(t,0,3)':volume=0[a2]; \ [0:a:0]volume=enable='between(t,0,3)':volume=0[a3]; \ ...

Get a camera with HDMI output and plug it in to a Blackmagic Intensity PCIe card or USB/Thunderbolt unit. Then use Adobe Flash Media Encoder to take that input and encode it into an RTMP/RTSP stream that a computer can easily play on the other via the network, plugged in to a projector or TV.

The solution seems to be to use both a different video and audio encoder. This line works: FFmpeg/ffmpeg -video_size 1024x768 -framerate 25 -f x11grab -i :0.0+0,0 -f alsa -ac 2 -i pulse -acodec aac -strict experimental output.flv I couldn't get it to work without -acodec aac -strict experimental, contrary to the HOWTO on ffmpeg wiki. The error message ...

If you're singing on the new track(s) you've added, definitely! I've done it myself. You can even pan the new track(s) left or right to give your song more "space". If you were thinking you'd take duplicate your audio track in Garageband, and change the pitch of the new track, it's harder. Your harmonies probably won't stay the same number of half steps ...

I am the author of the code you are reading. It appears you were an alpha user of Audacity 2.1.0 in advance of its release, which was only days ago. You have a version of the noise reduction effect with many experimental optional controls exposed to the user that are not in the release version. You may be interested in what I wrote here about the ...

After Effects works differently than normal video editors. To play audio on a composition (your video project), press 0 on the numeric keypad (or CTRL+0) to start the RAM preview. This way, After Effects loads the audio through the RAM. If you skip to parts of the video that are not in the green bar below your composition preview, you have to wait for AE to ...
