Andromeda Movie Creation

You can use the Andromeda application in order to create short or long movies. The correct term would be Motion Sequence Captures, as at this point, frames are saved individually in image files. This page will show you how to set sequence capturing and how to later encode the individual frames into desired movie format.

Encoding Sequence Captured Frames into Movies
Movie creation from sequence captured frames is easy as all frames are saved and numbered consecutively. Most tools used in images/movies conversions have the capability of still frame extraction from movies and vice verse. This section will show you how to encode the files into movies making use of the ffmpeg tool.

For a better explanation, we will assume that the Capturing Path has been set to C:\bitnova\captures. Also we will presume that the seq_ prefix has been used for the Folder Name Prefix option and the prefix of saved files is capture_. The recommended capture format when the proposed objective is to create movies is jpeg.

Now you may just follow these simple steps in order create the movie:


 * 1) Download and copy the ffmpeg.exe utility to your capturing path: C:\bitnova\captures. You can do all these steps in command line (Start->Run: cmd.exe), so here is the command line to be used to copy the utility: copy download_path\ffmpeg.exe C:\bitnova\captures
 * 2) Run the following command, assuming that the folder containing the frames you wish to encode are saved in the seq_0001 folder in your capture path: ffmpeg -r 20 -i seq_0001\capture_%04d.jpg movie.mp4

This will tell ffmpeg to encode all frames saved in the seq_0001 folder in a movie encoded using the mpeg4 video codec at a frame rate of 20 frames per second. You may play the movie in the Media Player Classic, a great free player for movies.

If you desire to use other container types (such as avi) just change the extension for the output movie file:

ffmpeg -r 20 -i seq_0001\capture_%04d.jpg movie.avi

Also you may change the video codec used in the data stream of the container file. For instance, to encode instead using mjpeg (Motion JPEG), you may use:

ffmpeg -r 20 -i seq_0001\capture_%04d.jpg -vcodec mjpeg movie.avi

Other options are available and you may want to consult the documentation available on ffmpeg tool. Probably the next most important setting you would wish to use would be the bitrate at which the video stream is encoded, to optimize the video quality of the resulting movie. You can use for this the -b option to specify the desired bitrate in kbps:

ffmpeg -r 20 -b 1800 -i seq_0001\capture_%04d.jpg -vcodec mjpeg movie.avi

In case you will observe a degradation in quality as a result of the ffmpeg conversion, you can also use the -qmax or -sameq options in the command line in order to balance the quality/size ratio. Even if encoding is made in mjpeg you will notice that by default, ffmpeg will try to minimize the movie size assuming that the frames in sequence are not changing too much. However this is not usually the case with sequencing in Andromeda, therefore you will need to specify the quality parameter.
