Animations in Beamer

You can create an animation in a portable way by using the overlaycommands to create a series of slides that are shown in rapid successionis a flexible but rather static approach since it CAN take some time toadvance from one slide to the nextit is mostly useful whem you want to explain each ldquopicturerdquo of theanimationmore ldquolivelyrdquo animations can be created by relying on a capability ofthe viewer program supporting showing slides only for a certainnumber of seconds (Acrobat Reader does in full screen mode)Syntax animate〈overlaySpecs〉the slides specified by the argument will be shown as quickly as possible











































































































































































animatevalue〈startSlide-endSlide〉〈name〉〈startValue〉〈endValue〉

〈name〉 must be the name of a counter or a dimension It will bevaried between two valuesfor the slides in the specified range the counter or dimension is set toan interpolated value that depends on the current slide numberon slides before the 〈startValue〉 the counter or dimension is set to〈startValue〉on the slides after the 〈endValue〉 it is set to 〈endValue〉

This text (and all other frame content) will fade out when the second slideis shown This even works with colored text

slide transition visual effect that is used to show the slidePDF in general and the Acrobat Reader in particular offer astandardized way of defining slide transitionsthe transition commands are overlay-specification-awaresyntax transitionCmdlt〈overlaySpecs〉gt[〈options〉]〈options〉 a list of 〈key〉=〈value〉 pairs Possible options

duration=seconds number of seconds the transition effect needsDefault one second Viewer applications especially Acrobat mayinterpret this option in slightly strange waysdirection=degrees for ldquodirectedrdquo effects specifies the effectrsquosdirection Values 0 90 180 270 and for the glitter effect also 315

Embedding movies in a Beamer presentation

Embedding a movie in a Beamer presentation

WarningUnfortunately currently there is no portable way of doing this and eventhe Acrobat Reader does not support this feature on all platforms

to include a video in a presentation a package is requiredmultimedia package it is part of the beamer package but it is notloaded automatically you have to include it explicitlymedia9 package very recent update (May 17 2019) comes equippedwith support for many video and audio formats (interactive Flash (SWF)3D objects (Adobe U3D amp PRC) MP4 FLV and MP3 both for file andinternet straeming) It is intended to be a complete replacement formovie15movie15 obsolete but still working nicely in some combinationviewerOS (Acrobat Reader DC + OS X for instance)



multimedia package stand-alone package that implements severalcommands for including external animation and sound files in a pdfdocumentcan be used together with both dvips plus ps2pdf and pdflatex

special sound support is available only in pdflatex

the hyperref package must be loadedmultimedia can be included both before and after hyperrefBeamer includes hyperref automatically



movie[options]〈posterText〉movieFileNameinserts the movie with the filename movieFileName into the PDF filefor safer execution the file must reside only in the directory in whichthe final PDF file resides

The movie file will not be embedded into the PDF file in the sense that theactual movie data will not be part of the mainpdf file The movie filemust hence be copied and passed along with the pdf file

what is meant when one says that the movie is ldquoembeddedrdquo in thedocument is just that one can click on the movie when viewing thedocument and the movie will start to playthe movie will use a rectangular area whose size is determined either bythe width= and height= options or by the size of the 〈posterText〉〈posterText〉 any TEX text such as a pgfuseimage command oran includegraphics command or a pgfpicture environment orjust plain text



structure1 the 〈posterText〉 is typeset in a box2 the box is inserted into the normal text3 the movie rectangle is put exactly over this box

the aspect ratio of the movie will not be corrected automatically if it isnot the same as the aspect ration of the 〈posterText〉movie can also include sound-only files in the PDF However for thisparticular purpose the sound command is availablestart only when the user clicks on it (unless further options are given)

Whether the viewer application can actually display the movie depends onthe application and the version

Examples Acrobat Reader v le 5 does not seem to be able to displayany movies or sounds on Linux Acrobat Reader v 6 on MacOS is ableto display anything that QuickTime can displayembedding movies in a PDF stated by the PDF standard



ExampleOS X 10145 Mojave Acrobat Reader DC (Arch x86_64 Build 20191220034)

Big Bang video

movie[width=linewidthheight=40cmborderwidth=1pt loop autostart showcontrols]Big Bang videoBigBangVideomov

in my personal case it works but it recognizes only QuickTime movformat and does not loop




Sample video

movie[width=60cmheight=40cmborderwidth=1pt loop autostart showcontrols]Sample videoSampleVideo_1280x720_1mbmov

in my personal case it works but with exceptions it recognizes onlyQuickTime mov format and does not loop



your viewer application is not able to render your movieif some external application is use the externalviewer option theviewer will launch an application for showing the movie instead ofdisplaying it itselfin this case the external application is started in a new windowwhich external application is chosen It depends on the viewer and theunderlying operating system settings



Available optionsautostart the movie starts playing immediately when the page isshown At most one movie can be started in this way When the pageis no longer shown the movie immediately stopsborderwidth=TeXdimen thickness of a border to be drawn aroundthe movie (too small borders can cause troubles)depth=TeXdimen overwrite the depth of the 〈posterText〉 boxduration=nSecs how long the movie should be shown in secondsnSec may be a fractional value and must be followed by the letter ldquosrdquoIn conjunction with the start option allows to not to display a partof the movieexternalviewer causes an external application to be launched fordisplaying the movie in a separate windowMost options have no effect since they are not passed along to theviewer applicationheight=TeXdimen overrides the height of the 〈posterText〉 box



label=movieLabel a label such that it can later be referenced bythe command hyperlinkmovie (used to stop it or to show adifferent part of it) It is not a normal label it is inserted literally intothe pdf code so it should not be too fancyloop starts again the movie when the end has been reachedonce the movie just stops at the end (the default)open causes the player to stay open when the movie has finishedpalindrome the movie starts playing backwards when the end hasbeen reached and starts playing forward once more when thebeginning is reached endlesslyposter asks the viewer application to show the first image of themovie when the movie is not playingrepeat the same as loopshowcontrols=〈true or false〉 a control bar to be displayed belowthe movie while it is playing Default no control bar is shownstart=nSecs the first nSec seconds are skippedwidth=TeXdimen overwrites the width of the 〈posterText〉 box



hyperlinkmovie[options]movieLabeltextThe text becomes a movie hyperlink by clicking on text the movie withthe given label will execute the action given in options (start or stop orpause or resume)

The movie must be on the same page as the hyperlink

Many options are the same as for the movie command If different valuesare given to the same option the option for the link takes precedence

duration loop repeat once palindrome showcontrolsstart all behave the same way as for the movie commandpause suspend the playback if it was playing else do nothingplay play from position start If it is already playing stop andrestart at the start position (the default)resume resumes playback if it has previously been paused If has notbeen paused but not started or already playing do nothingstop end the playback



Alternative the media9 packagevideo and sound files require an additional Flash (SWF) applicationwhich must be either embedded into the PDF or loaded at runtimemedia9 package comes with an enhanced versione of the highlyconfigurable open-source StrobeMediaPlaybackswf maintained byAdobe and hosted on SourceForgenettwo additional simple players VPlayerswf for the video andAPlayerswf for the audio are included which are compatible withthe older Flash Player 9 plugin (bundled with the Reader for Linux)they provide sufficient functionality for playing embedded files andstreamed mediaa simple image gallery viewer SlideShowswf is also included whichcan display collections of embedded and remote images in the PNGJPEG and GIF file formatsmedia9 is based on the RichMedia Annotation (annotations areinteractive elements in a document) an Adobe addition to the PDFspecification



includemedia[options]posterText〈main Flash (SWF) file or URL〉 | 〈3D (PRC U3D) file〉

last argument is the main interactive application to be inserted into the PDFin the case of Flash this can be a local SWF file or a URL such as aYouTube video playera local file will become part of the final PDF file while Flash content from aURL requires an internet connection when the user activates it in AdobeReadera local file (main application or resource) will only once be physicallyembedded in order to keep the final PDF file size small If the same file(identified by MD5 checksum) appears in other includemedia commandsonly a reference will be inserted that points to the same storage location inthe PDFposterText defines the size of the rectangular region in which the mediawill be displayed Moreover it will be shown in case the media has not beenactivated It can be anything that LATEX can typeset or it can be left blank (inwhich case the size of the media rectangle should be set with options widthand height)




(Loading video )includemedia[

label=sampleVideo width=linewidth height=045linewidth addresource=SampleVideomp4 transparent activate=pageopen passcontext flashvars=

source=SampleVideomp4 amploop=false

]small (Loading videodots)

VPlayer9swf

in my personal case it seems not to work properly and can read mp4 filesonly


var ocgs=hostgetOCGs(hostpageNum)for(var i=0iltocgslengthi++)if(ocgs[i]name==MediaPlayButton0)ocgs[i]state=false


with media9 a list of directories can be given where to look for mediaand resource filesaddmediapathdirName

this command appends one directory at a time to the search list Tospecify more directories just use it repeatedly The path separator isalways ldquordquo independent from the operating systemmedia9 package recognizes the format for 3D visualization and hasappropriate optionsit cam also interact with Flash by means of Flash variables



(some) available options

label=width= height=totalheight=keepaspectratioscale= addresource=flashvar=amp (Flash only)

attachfilesdraft= finalplaybutton= (fancy | plain |none) noplaybuttonwindowed transparentpasscontext (Flash only)

activate= (onclick | pageopen | pagevisible)deactivate= (onclick | pageclose | pageinvisible)

If a Flash variable is set to point to an embedded resource the value of thevariable must be given in exactly the same way as with the addresourceoption Otherwise the name of the embedded file cannot be resolved

In addition there are a lot of options to load 3D objects into the PDF fileThey are all prefixed by ldquo3Drdquo



Alternative the movie15 package (obsolete not updated since 2012)includemovie[options]widthheightfileName

width height horizontal and vertical dimensions of the display areathe media clip is scaled to fit width and height or if they are empty to fitthe size of the ldquoposterrdquo text box given as argument to the textif the media file is ldquoembeddedrdquo as part of the final PDF output (the default)it may reside wherever TEX or Ghostscript search for input files depending onthe PDF producing methodAvailable options attach autoclose autopause autoplay autostopautoresume continue controls toolbar depth= draftexternalviewer final inline= (false disables the automaticembedding of the media) label= mimetype= mouse= (enabledisablemouse interacction) palindrome playerid=〈playerid〉 (force a particularplug-in) poster poster=〈image〉 rate=〈rate〉 (speed rate 2 1 05 -1 ) repeat startat=〈offset〉 endat=〈offset〉 (〈offset〉 given astime〈nSeconds〉 frame〈frameNum〉 marker〈quotedString〉) text=url volume

in my personal case it seems to work but it can get Acrobat Readercrashes when used together with the other two packages
