You can use WMV instead of AVI for unlimited file length. DevWare does not use compression with AVI. Usually the codec is just RGB-24. WMV is compressed in software.

  • There is a frame rate value stored in the wmv file. There is a check box and numerical entry on the Sensor Control -> Video Record dialog page where you can provide a frame rate to put in the file. If that is not checked DevWare uses the Display FPS.
  • But that value comes from before recording started. During recording there could be considerable disk overhead or compression overhead so that the actual frame rate during recording is lower than it was before recording started. In that case the frame rate in the file will not match the actual frame rate of the recording.

The compression quality for MPEG-4 or WMV recording can be controlled with the "VidCap Quality" STATE variable.

  • RAW files will play back in DevWare, but will need to be converted to AVI to be imported into other applications. You can use DevWare as a RAW to AVI file converter. Load the RAW file in DevWare and verify that the image looks correct. On the Video Capture dialog page select AVI recording format and turn off Capture to RAM. Click the Stop button on the Toolbar(See 2.2.2). Click the Record button on the Toolbar(See 2.2.2).
  • The "Frame rate" listed in the info.txt file (RAW only) is the rate displayed on the Info Panel "FPS (Display)".
    A specific frame rate can be set via Sensor Control / Video Record "Specify playback frame rate", or via the INI file using the STATE commands "VidCap Auto Play FPS" and "VidCap Play FPS".
  • “Specify playback frame rate”; DevWare video playback speed is not precise.
