✘ Commands Available -

• `{i}compress <reply to video>`
    optional `crf` and `stream`
    Example : `{i}compress 27 | stream` or `{i}compress 28`
    Encode the replied video according to CRF value.
    Less CRF == High Quality, More Size
    More CRF == Low Quality, Less Size
    CRF Range = 20-51
    Default = 27
