This section of the CVB Movie Manual describes the functionality and the usage of the Movie Interactive program.
CVB Movie Interactive is available as an executable program and is installed with the CVB Movie Tool (%CVB%Applications).
The program allows recording of images to RAM or to harddisc and saving them as a video file in AVI format or as single image files.
The image source can be any image acquisition device (such as a framegrabber or camera) which is supported by CVB.
Also it is possible to use existing Video Emulators or Video Files to load image streams into the program.
It allows
•a compression codec to be selected,
•selection of image areas,
•frame skipping and
•to write a time-stamp to the image.
To deal with the increasing use of image acquisition devices which output a Bayer image, the program has the option to convert this monochrome Bayer image directly to a color RGB image.
This is possible during recording and also afterwards using a Video File.
The two methods of acquiring images and saving them as a video file are:
RAM Recording:
The images from the camera are transferred into a Ringbuffer (allocated memory in RAM), where the number of buffers is given by the user and
are read out if the user presses the appropriate button.
After that the images are saved to disc as an AVI file.
This method enables the saving of images acquired previously.
There are two methods for RAM Recording implemented:
•Ringbuffer to file - Start Event
•Ringbuffer to file - Stop Event
Harddisc Recording:
The images from the camera are directly transferred to the system and then saved to hard disc.
Also it is possible to save the frames each by each into single files.
