Alternatively you can have ffmpeg generate the black video with the color source filter instead of making an image: ffmpeg -f lavfi -i color=c=black:s=1280x720:r=5 -i audio.mp3 -crf 0 -c:a copy -shortest output.mp4 Since it is just black video this is one case with lossless mode (-crf 0) will have a smaller file size than the default lossy mode. The ...

You create the whole graphic as a still image - for the above, likely a 1080 x 28000 px image to start with. Then I'd import the image into either Premiere or After Effects based on what you're more comfortable using. Then you set a keyframe on the initial position of the graphic - then move the graphic horizontally to the left, all the way to the end, ...

Youtube requires a video stream but your image is a single frame. Loop it to create a stream and terminate output when audio ends by adding -shortest. ffmpeg -loop 1 -i black.png -i 'input.mp3' -c:v libx264 -tune stillimage -shortest 'output.mp4' I don't remember if YT accepts MP3 in MP4. If it does, you can keep -c:a copy. -pix_fmt yuv420p is usually ...

I presume you generally talk while typing, right? Well, when I need to focus on a human voice, any distracting sound is unwelcome. This includes keyboard typing. I do not see any benefit of such sounds when making tutorials during parts when you talk. Also, keep in mind that people with hearing aids will benefit much from a clean voice with no other sounds. ...

The quality of the headphones will only affect how the audio sounds to you, so you don't necessarily need to spend your money on that to improve the audio for a youtube video. I would suggest focussing your money on the mic itself. This is a great roundup of relatively inexpensive mics, with audio clips so you can hear how they sound. Gaming headsets tend to ...

Audio is not my expertise, i try my best. The problems of your source are volume is low speech is fast sound is dull bass is insufficient treble is high Therefore, I use the command to find the max volume ffmpeg -i source.wav -af "volumedetect" -vn -sn -dn -f null /dev/null , which is -6.4dB, then i transform the max volume to 0dB by using audio ...

The method used in your example is called "stop motion" and is pretty much the way people create their lego-videos, clay-animations, etc. To do this, you will need to take a picture of the paper, then rotate it very slightly, take another picture, rotate some more, and so on and so forth. When you took all the pictures, you can import them as an ...

Depending on your country, the website you're uploading to and your usage of both audio and video, the copyright-laws make it legal or illegal to use a specific song. If you create a video-essay about music-production and must use the song as an example to show your point, you will, in many cases and places not break any laws. If you combine a still-image ...

There are a couple of things which you may still tune in the x264 encoder like listed here but also in the mp3 decoder like shown here if you are OK with a lower audio bitrate.My assumption is that not everything is eaten up by the video. I have tried ffmpeg -loop 1 -y -i image.jpg -i audio.ogg -shortest -acodec mp3 -qscale:a 7 -vcodec libx264 -preset ...

Webm and mp4 are container formats. Those itself don't have any relevant influence on the file size. The codec with a set bitrate determines the filesize. For YouTube uploads, follow the current recommendations and you'll see, you should use h264 as video codec. First, make sure the export has the same resolution and frame rate as the input, unless you ...

Probably becaue pixel format is wrong, add to command: -pix_fmt yuv420p

You can add a music visualizer to videos for free online using VEED. (Disclaimer, I am the developer of this software)

I personally use RaceRender, however, there is also DashWare. Both can edit video and add GPS position overlays. Bare in mind, neither of them can add the actual "map" like one from Google Maps, just a line showing your path and a marker showing the current location. Again, my personal preference is to use RR or DW to produce a video with a magenta ...

Use proxy videos to transcode the mts files into something usable. Here's a short tutorial to get you started:

I don't think it really matters. People do both all the time. It really all just comes down to the content you provide, using appropriate tags on each video, and being consistent with your postings.

The problem was that different clips had different frame rates. My phone records a variable frame rate around 30 fps, the Zoom video had a fixed frame rate of 25 fps, the FB live video was variable around 30 fps and the Acapella-via-FB video was fixed 30 fps. I fixed the problem by reencoding all clips to a fixed frame rate of 30 fps with ffmpeg -r 30. (I ...

Your workflow is wrong. You just don't normalize audio with After Effects. Instead either do it with an audio editor, like Audition (which seems suitable to match clips in timeline, just use the normalize effect and maybe a compressor if the dynamic is too great). Finally apply loudness normalization with your video editor. For example during export with ...

I'm not familiar with facebook video, and maybe someone else can help with that. 70MB is insanely small for 30 mins of video. What are the properties of the source video (in Premiere, right click the source video, select Properties). Copy/Paste that info, and add it to your question if you can. Leave the frame size / frame rate the same as the original - ...
