swfcombine - Man Page

a tool for combining swf (flash) files


swfcombine [-rXYomlcv] [-f] masterfile [-xysf] [(name1|#id1)=]slavefile1 .. [-xysf] [(nameN|#idN)=]slavefileN

swfcombine [-rXYomv] --stack[1] [-xysf] [(name1|#id1)=]slavefile1 .. [-xysf] [(nameN|#idN)=]slavefileN

swfcombine [-rXYov] --cat [-xysf] [(name1|#id1)=]slavefile1 .. [-xysf] [(nameN|#idN)=]slavefileN

swfcombine [-rXYomlcv] --dummy [-xys] [file]


Take two or more SWF files, and combine them into a new SWF. SWFs can either be stacked (no masterfile is present) or inserted (into the masterfile).

SWF files are animation files which can be displayed in Web Browsers using the Flash Plugin.

For template mechanisms, it's often convenient to separate the processes of generating small animation fragments and merging them into a big movie. swfcombine can be used to perform the latter.


-o,  --output outputfile  

   explicitly specify output file. (otherwise, output.swf will be used)

-t,  --stack

   Don't assume the first file is a master file. Instead, store each
   file in a seperate frame.

-T,  --stack1

   place each slave in the first frame (no master movie)

-m,  --merge

   Do not store the slave files in a sprite/MovieClip. Instead, merge the files frame by frame.

-a,  --cat

   concatenate all slave files (no master movie)

-l,  --overlay

   Don't remove any master objects, only overlay new objects

-c,  --clip

   Clip the slave objects by the corresponding master objects

-v,  --verbose

   Be verbose. Use more than one -v for greater effect

-F,  --flashversion

   Set the flash version of the output file.

-d,  --dummy

   Don't require the presence of slave objects. Usually used together with -X, -Y or -r.

-f,  --frame

   The next slave replaces a frame, not an object. Therefore the slave identifier is a
   frame number (#frame=) or frame label (framelabel=).

-x,  --movex xpos        

   x Adjust position of slave by xpos pixels

-y,  --movey ypos        

   y Adjust position of slave by ypos pixels

-s,  --scale scale      

   Adjust size of slave by scale percent (e.g. 100% = original size)

-r,  --rate fps  

   Force the output to have the framerate fps. (Otherwise, the framerate of the master file will be used)

-X,  --width width      

   Force movie bbox width to width (default: use master width (not with -t))

-Y,  --height height      

   Force movie bbox height to height (default: use master height (not with -t))

-N,  --local-with-networking

   Make output file "local-with-networking"

-G,  --hardware-gpu

   Set the "use hardware gpu" bit in the output file

-B,  --accelerated-blit

   Set the "use accelerated blit" bit in the output file

-L,  --local-with-filesystem

   Make output file "local-with-filesystem"

-z,  --zlib zlib        

   Use Flash MX (SWF 6) Zlib encoding for the output. The resulting SWF will be
   smaller, but not playable in Flash Plugins of Version 5 and below.

Combining two or more .swf files using a master file

Of the flash files to be combined, all except one will be packed into a sprite structure (Movieclip) which will then be inserted into the master .swf file. This means that, in terms of trees, when combining several flash files, one will form the root of the tree, while the others will be appended to the root as a subnode. The user has to specify which of the files will become the root of the tree ("master") and which will be the appended nodes ("slaves"). The slave files must all have a name, which is then used to determine their exact position inside the master file. The slave files will then be converted into sprites, inserted into the master file, and all PlaceObject tags in the master file which match the name of the slave file will be updated to correctly display the slave sprite. The slave name may also be the object id, preceded by '#', in which case  the object to be replaced is referenced by id and not by instance name.

Combining (stacking) one or more .swf files without a master

The flash files will be inserted in seperate frames. They will still be packed into Movieclips, therefore the outputfile will have exactly as many frames as there were inputfiles. Also, the files don't need to have names. If you want to access the Movieclips, their names are frameXX, where XX is the decimal number of the file, starting by zero (00).


Create two flash movies. Insert some rectangle into one of them, and give it a name. (E.g. "foo") Now call

swfcombine -o combined.swf master.swf foo=slave.swf

As a result, the slave movie should be visible inside the master movie at the position where the rectangle used to be.
