Output 1: The video was update and encoding was set on the file.

This should be set to true in most cases unless you really want to keep multiple video streams. When checked the first video stream will be used and the other will be disabled.

When force is checked, the video will be forced encoded even if it was already in the desired codec. If not it will fall back to using CPU encoding of H264.

If this is set, the flow executor will determine if the Flow Runner can first hardware encoding in this order h264_nvenc (NVIDIA GPUs), h264_qsv (Intel), h264_amf (AMD), h264_vaapi.If not it will fall back to using CPU encoding of H265/HEVC. If this is set, the flow executor will determine if the Flow Runner can first hardware encoding in this order hevc_nvenc (NVIDIA GPUs), hevc_qsv (Intel), hevc_amf (AMD), hevc_vaapi.You can set the codec to these magic values and leave the parameters blank.

This node will set all video streams in the file to encode using the video codec specified and the encoding parameters specified. Resolution: 1920 x 1080 Frames Per Second: 60 Video Format: ITU H.264 Audio Format: MPEG 1 Audio, Layer 3 (MP3) The resolution and FPS are well beyond what I require, so I'm trying to run a command to scale things down: ffmpeg -i highres.avi -r 30 -s 960x540 lowerres.
