How to use multiple variables in time calculator c#
- by Peter O'Dwyer
I am building a video time calculator and need to use the number of frames instead of milliseconds.
e.g
25FPS
HH:MM:SS:FR
00:00:10:24 <-- Last frame of 10 seconds
00:00:11:00 <-- First frame of 11 seconds
My problem is that if the start frames are lower than my end frames it can't calculate the time.
00:00:10:05 <-- Start
01:00:10:10 <-- End
00:59:59:05 <-- Answer which I can't get!!
HERE'S MY CODE
string Startdate = Dur_txtStart.Text;
string Enddate = Dur_txtEnd.Text;
string Startdate1 = Startdate.Substring(0, 8);
int Startframe1 = Convert.ToInt32(Startdate.Substring(9, 2));
string Startdate2 = Enddate.Substring(0, 8);
int Startframe2= Convert.ToInt32(Enddate.Substring(9, 2));
TimeSpan diff = DateTime.Parse(Startdate2).Subtract(DateTime.Parse(Startdate1));
int frameDiff = Startframe2 - Startframe1;
int Hour = Convert.ToInt32(diff.Hours);
int Min = Convert.ToInt32(diff.Minutes);
int Sec = Convert.ToInt32(diff.Seconds);
if (frameDiff < 0 && Sec > 0)
{
Sec -= 1;
string frameDiffBuild = string.Format("{0}:{1}:{2}:{3}",Hour.ToString("D2"), Min.ToString("D2"), Sec.ToString("D2"), (Convert.ToInt32(Dur_txtFPS.Text + frameDiff)).ToString("D2"));
Dur_txtOutTime.Text = frameDiffBuild;
}
else
{
string frameDiffBuild = string.Format("{0}:{1}:{2}:{3}",Hour.ToString("D2"), Min.ToString("D2"), Sec.ToString("D2"), frameDiff.ToString("D2"));
Dur_txtOutTime.Text = frameDiffBuild;
}
Hope you can help guys my head is mashed!
