Beroende p\u00e5 vad du ska testa med den h\u00e4r k\u00e4llan m\u00e5ste du v\u00e4lja ett visst testm\u00f6nster.

Den h\u00e4r bilden hj\u00e4lper dig att testa dimensionerna och pixelnoggrannheten i din videopipeline: Den stora cirkeln visar t.ex. om den resulterande videon har r\u00e4tt bildf\u00f6rh\u00e5llande. Med de vertikala r\u00e4nderna i mitten kan du se om alla dina pixlar kommer igenom och vilka artefakter en videokomprimering kan orsaka. V\u00e4nligen kontrollera detta wikipedia-sida<\/a> f\u00f6r detaljerad information om vad omr\u00e5det \u00e4r bra f\u00f6r.<\/p>\n\n\n\n

Anv\u00e4nd detta testm\u00f6nster f\u00f6r att kontrollera alfakanalen n\u00e4r du spelar ut en key- och fill-signal via SDI<\/span>. Vissa videomixrar\/switchers anv\u00e4nder en Clip- och Gain-inst\u00e4llning f\u00f6r att best\u00e4mma hur tangenten ska anv\u00e4ndas.

Inst\u00e4llning av renderingsstorlek<\/h3>\n\n\n\n

Som standard genererar testk\u00e4llan f\u00f6r videoutg\u00e5ng en bild som \u00e4r lika stor som programmets utmatningsdimensioner. Om du beh\u00f6ver andra pixeldimensioner kan du v\u00e4xla alternativet Render Size fr\u00e5n \"Document Size\" till \"Custom...\". Testm\u00f6nstret r\u00e4knas om baserat p\u00e5 bredd och h\u00f6jd och f\u00f6rblir pixelnoggrannt.<\/p>\n\n\n\n
