Hi anurag,

  Are you using writetoavi function?

Thanks and regards,

Actually I was been told to convert the video into jpeg and then display them rapidly so that it appears as a video.

Problem is that I have 600 jpeg and to display them consumes time and the video does not appear to run continuously so what am I suppose to do.

Please help.

Hi anurag,

  If you are using writeto avi function,first thing you need to consider is frame rate and codec....these two parameters will decide how should a video file should run and in which player it should run.....Say if you want 30frames per second....then each image should run at every 1/30 seconds..means your for loop should iterate at that speed...

Can you post a vi how you have done.

Thanks and regards,

I have been given the attached file(vi)for reference

Please go through it and let me if I am on the right path..

Hi anurag267,

  Place a timedelay Vi  and wire to 33..i.e for very 33 ms..one image is written to the picture indicator...

Thanks and regards,
