Phota  -  Video Options

Video Options The Video Options screen allows configuration of parameters that control the capture of Phota display sequences as animations.  Either AVI / MP4 / 3GP, Windows Media Video (WMV) or Still Image Files Sequence animations can be produced, selected via the Video Format drop-down box.  The Video Parameters Set choices are Standard Video, DVD - NTSC, DVD - PAL or HD DVD/Blu-ray.  The Encoding API can be set to either DirectShow or Media Foundation, which will determine the technology used to encode Video and Audio data.  A Video Compressor drop-down box allows selection from among the Video encoder codecs currently available on your computer.

Optionally, Audio can also be captured by checking Capture Audio and selecting an Audio Device and an Audio Compressor.  NOTE:  Most sound cards can provide a Stereo Mix Audio Device, but often it is not enabled, and might not even be visible.  The Sounds Control Panel can usually be used to enable Stereo Mix (right-click the speaker icon in the Taskbar tray).  An internet search for 'enable stereo mix' will quickly find detailed instructions on how to do this.

When using the Still Image Files Sequence Video Format, the Video and Audio Compression areas of the screen are replaced with Image Sequence options.  Sequential still images will be saved in the selected Image Files Format (i.e. jpg, png, tiff, etc.)  A Default Images Save Directory can be chosen by pressing the Select button.  Optionally, a new sub-directory can be created to contain image files for each capture.  Image files will be saved with sequential 8-digit numbers, which can optionally be prefixed with the current date and time.  The Save Only Changed Scenes option will output an image file only when the display has actually changed, potentially saving much disk space.  Otherwise, images will be saved at the specified Capture Frames/Second rate.  Check the Output Image Sequence Control File option to create a small file with each capture that contains timing information for each image frame.  The Sequence Control File can be used with the Image Sequence Player to provide much greater control over the playback of captured Image Sequences.  The Default to Use Intended Time option will play sequences back by default according to the Intended Times for frames (as recorded in the Sequence Control File), instead of the Actual Times.
