Ffmpeg scale plugins manual#

I attached 2 sample files, the first one is the one Audacity processed with DRC Enabled, the second one with DRC Disabled. Why would you allow audio to be edited in a compressed state in audacity? Doesn't it make more sense to uncompress audio to its fullest for best editing? Isn't that why Audacity works with Waves only? What's the point of the Waves when they are affected by compression? If people want to apply DRC to their ac3 exports, they can always chose to do so in post processing. Look man, Audacity is not an audio player, it's an advanced audio editing tool.

If the input image format is different from the format requested by the next filter, the scale filter will convert the input to the requested format. I export AC3s to WAVE after editing as to not further degrade the audio (but even if I compress back to lossy, I would not be able to hear a difference tbh). That's a different issue you're describing. If you are exporting in a compressed format, then some degradation is inevitable, simply because the audio has been subject to lossy compression twice. And, after FFmpeg changes the resolution of the video, it will re-encode it at that resolution. That’s it With this simple command, you can change the video’s resolution with FFmpeg. For example, you could use -vf scale640:480 to resize your video to 480p. where, w and h denote the required width and height of the destination video.

For each version of ffmpeg.wasm, there is a default version of ffmpeg/core (you can find it in devDependencies section of package.json), but sometimes you may need to use newer version of ffmpeg/core to use the latest/experimental features. ffmpeg -i input.mp4 -vf scalew:h output.mp4. ffmpeg scale plugins

Why is Ableton Live able to scale plugins properly on 4K monitors in WIN. Use other version of ffmpeg.wasm-core / ffmpeg/core. All my videos sound worse than the source videos/source DVDs. The most common techniques of feature scaling are Normalizationffmpeg -i input.
