Typ
Chcete-li vytvořit obrázek, potřebujete určitý stupeň kompozičních a barevných dovedností. Tvorba animace také vyžaduje základy v umění a produkce videa a zvuku vyžaduje profesionální znalosti a dovednosti.
Typy multimediálních materiálů
Obecně lze říci, že podle různých formátů souborů materiálů uložených na disku lze materiály rozdělit na text, zvuk, obrázek, animaci, video atd.

Text
Text odkazuje na písmena, čísla a symboly. Ve srovnání s jinými médii je text nejsnáze zpracovatelný, zabírá nejmenší úložný prostor a je nejpohodlnější pro zadávání a ukládání.média.Zobrazení textu je velmi důležitou součástí vícenásobného výukového softwaru, základního softwaru, definic softwaru, základního softwaru. výrazy, názvy, nabídky, tlačítka, navigace atd. jsou skutečně oddělitelné od textových informací .Je to důležitý mediální prvek pro přesné a efektivní šíření informací o výuce. Text je běžně používaným mediálním prvkem.
Formát souboru a funkce:
.TXT: TXTtext je prostý textový soubor a není naformátovaný, to znamená, že není relevantní písmo, velikost, informace o formátování, jako je barva a umístění. „Poznámkový blok“ systému Windows je nástroj pro úpravy a ukládání, který podporuje TXTtext.
.DOC:DOC je formát souboru používaný softwarem pro zpracování textu.
.WPS:WPS je formát čínského softwaru pro zpracování textu, který obsahuje jedinečné informace o přerušování řádků ao nastavení typu. Říká se jim formátovaný text a lze je upravit pouze v určitých verzích softwaru pro úpravy WPS.
.RTF:Popište obsah prostým textem, který může ušetřit různé formáty informací a lze jej vytvořit písemně, Word atd. Také známý jako formát RichTextFormat (RichTextFormat), který se obecně odkazuje na RTF, je na různých platformách formátem wordových dokumentů vytvořeným pomocí RTMi softwaru vyvinutého na crosoftu. dokumenty.

Pravidelná aplikace výukového vybavení
Obrazový materiál:Pokud se při výrobě výukového vybavení podílejí obrázky, obvykle se používá formát JPG a velikost se řídí v rozmezí 100–200 kB; Pokud se používá grafika, formát GIF se obecně používá a velikost se řídí pomocí 100.
AudioMateriál: Obecně používejte zvukové soubory ve formátu WMA nebo MP3 a průtok je řízen v rozmezí 16~128 kb/s.
Animationmaterial:generallyuseGIFandSWFformatanimationfiles,theformerissuitableforsmallcartoonanimation,thesizeiscontrolledwithin100K,thelatterissuitableforvarioustypesofanimation,interactiveIthasstrongperformance,smoothplayback,andthesizeisgenerallycontrolledwithin10M.
