So I can't figure out how to do an actual audio passthrough because of this A/V Media node. But of course I don't get the burned-in Time Code on the video. And whenever I submit a file to the ' A/V Media' decoder node, regardless of its 'Audio decode' settings (= whether I pick 'No decode', 'Full decode' or 'Intelligent') the audio ends up being re-encoded as PCM, and all the channels are remapped as mono tracks (even if the 'Force output audio channel' is set to 'Same as source').Īlso if I disable both A/V Media and Time-code nodes, the audio is properly passed through (same AAC codec and same channels/tracks map as the source). The problem is, because I need the burn-in 'Time Code' filter node, this requires an A/V Media decoder node upfront. No particular problems for the video part, but I would like the audio to be an actual passthrough (= no remap, no re-encode of audio). It is also possible to rotate videos with FFmpeg: ffmpeg -i example-video.mp4 -vf 'transpose=2 ' output-rotate.Code: Select all -map 0:v -vcodec prores_ks -profile:v 0 -qscale:v 16 -acodec copy -map 0:a >

The concat parameter here combines your files. Then, run the following command: ffmpeg -f concat -i my-video-list. Enter the list of videos you want to merge into a. Imagine you have multiple clips encoded with the same codec.

scale: You can specify the scale sizes you want in your output with this parameterįFmpeg also allows you to combine multiple videos.

-vf: This parameter works the same as the -filter:v argument seen above.

The following command will resize the video to a size you want: ffmpeg -i example-video.mp4 -vf scale=1920:1080 output-scale.mp4 Sometimes you also need to change the scale of the video.

Editing videos doesn't end with just trimming and cutting.
