Thanks ! In some cases, I may need also the framerate, thus I could edit the file to create a second bat : can you give just the line to be added in the script ? No need to post another bat. Suggestion : if there is nothing after the point, write only what is before, thus for 30.000 FPS, write only 30, but if i's 29.970, write 29.97. In other words, remove everything atfer the last digit which is not a 0, but only after the point of course (if possible), not to have 3 instead of 30. Sorry to be boring :o ;)
