AV1 FFmpeg Command: Set Video Encoder has invalid values for preset

[taltamir]

AV1 FFmpeg Command: Set Video Encoder lets you choose a preset between 9 string values from veryslow to ultrafast.

No matter what you pick it won't change anything in the ffmpeg command. it should but it does not.

it should instead let you choose a numerical value between 0 and 13 as per
https://trac.ffmpeg.org/wiki/Encode/AV1#Presetsandtunes

and whatever number you input should then be used in the ffmpeg command
