Тип
За да направите картина, се нуждаете от определена степен на композиция и цветни умения. Създаването на анимационен филм също изисква основа в изкуството, а производството на видео и аудио изисква професионални знания и умения.
Видове мултимедийни материали
Общо казано, в зависимост от различните файлови формати на материалите, съхранени на диска, материалите могат да се разделят на тип текст, звук, изображение, анимация, видео и т.н.

Текст
Текстът означава букви, цифри и символи. В сравнение с други медии, текстът е най-лесен за боравене, заема най-малко място за съхранение и е най-удобен за компютърно въвеждане и съхранение. ,принципи,проблемни изрази,заглавия,менюта,бутони,навигация и т.н.са реално отделими от текстова информация .Това е важен медиен елемент за точно и ефективно разпространение на учебна информация. Текстът е често използван медиен елемент.
Файлов формат и функции:
.TXT:TXTтекстът е обикновен текстов файл и е неформатиран,това няма подходящ шрифт,размер,информация за форматиране като цвят и местоположение.„Бележникът“ на системата на Windows е инструмент за редактиране и съхранение, който поддържа TXTтекст.Всички софтуерни програми за редактиране на текстове и инструменти за интегриране на мултимедия могат директно да извикват файлове с текстов формат TXT. свръхсилен,
.DOC:DOC е файлов формат, използван от софтуер за обработка на думи.
.WPS:WPS е форматът на китайски софтуер за обработка на текст, който съдържа уникална информация за прекъсване на реда и настройка на типа. Те се наричат форматиран текст и могат да се редактират само в определен WPS софтуер за редактиране.
.RTF: Опишете съдържанието в обикновен текст, който може да запазва различни формати на информация и може да бъде създаден в писмен вид, Word и т.н. Известен също като RichTextFormat(RichTextFormat, обикновено наричан RTF) е междуплатформен формат на документи, разработен от MicrosoftCorporation.Mostwordprocessing софтуерът може да чете и запазва RTF документи.

Звук
Звукът обикновено има три форми: глас, звукови ефекти и музика. Гласът се отнася до звука на говорещите хора; звуковите ефекти се отнасят до специални звукови ефекти, като дъжд, мелодии, машинни звуци, животински звуци и т.н. Може да бъде записан от природата или изкуствено симулиран чрез специални методи; музиката е вид на най-често срещаната форма на звук.

Файлов формат и функции
.AVIAVI(AudioVideoInterleave) е видеофайлов формат, разработен от Microsoft за кръстосано записване на аудио и видео. В AVI файловете аудио и видео данните се подреждат и съхраняват и по време на възпроизвеждане може да се получава непрекъсната информация. Този вид видеофайлов формат е гъвкав и няма нищо общо с хардуера. Може да се използва в компютър и Microsoft Windowsсреда.

Потребителите се наслаждават на музика или видео на уеб страници, използвайки тази технология, и могат да използват RealPlayer, за да слушат или гледат, докато ги изтеглят, вместо да чакат целият файл да бъде изтеглен преди слушане или гледане. или файлове с формат за поточно предаване и тяхното разширение е.RM,.RA или.RAM. При създаването на мултимедийни уебстраници той се превърна във важен мултимедиен файлов формат. Ако искате да използвате технология за "поточно предаване" като файлове в реален формат в уеб страниците, се изисква не само поддръжката на браузъра, но и уеб сървър, който поддържа поточно предаване.

Формат на материала
Въведение
На практика често се случва, че поради неправилен избор на формата за съхранение на картини, аудио, анимация и видео, софтуерът за мултимедиен курс заема много място и качество. Следователно балансирането на връзката между размера на файла и качеството е основно съображение при създаването на софтуер за курс.
Undernormalcircumstances,thelargerthestoragespaceinthecomputer,thebetterthequalityofmaterialsofthesametypeandthesamecontentbutindifferentformats,butthiswilldirectlyleadtolargecourseware,difficulttotransmit,andwasteofsystemresources.Therefore,whenchoosingmaterials,besuretochoosefilesofmoderatequalityandformat.
Редовно прилагане на курсов софтуер
Картинен материал:Ако изображенията са включени в производството на курсов софтуер, обикновено се използва JPG формат и размерът се контролира между 100-200 KB; Ако са включени графики, обикновено се използва GIF формат и размерът се контролира в рамките на 100 KB.
Аудиоматериал: Обикновено използвайте аудиофайлове във формат WMA или MP3 и скоростта на потока се контролира между 16~128Kb/s.
Animationmaterial:generallyuseGIFandSWFformatanimationfiles,theformerissuitableforsmallcartoonanimation,thesizeiscontrolledwithin100K,thelatterissuitableforvarioustypesofanimation,interactiveIthasstrongperformance,smoothplayback,andthesizeisgenerallycontrolledwithin10M.
Видеоматериал: Често се използват видеофайлове във формат WMV и скоростта на потока се контролира на данни около 250 KB/S.

Как да получите
Материалите за софтуер за мултимедиен курс могат да бъдат грубо разделени на няколко основни форми като текст, графики, изображения, аудио (звук), видео и анимация.
Текстов материал
Текстовият материал обикновено се запазва като файлов текст. Често срещаните формати са: txtfile,docfile,rtffile,wpsfile,pdffile и др.
Въвеждането на файла обикновено използва клавиатурата и може да бъде въведено и на ръка.
Обикновено текстовите материали идват от учебниците и научените материали, уебсайтове и т.н.
