What is Dotnet Timecode?

Dotnet Timecode is a C# class library for working with SMPTE Timecodes defined by the Society of Motion Picture and Television Engineers in the SMPTE 12M specification.

The library allows the user to construct timecode objects, manipulate timecode values, and convert between the most common framerates, including drop frame framerates such as 29.97DF and 59.95DF.

How do I get started?

Get the latest nuget package using the dotnet CLI

dotnet add package DotnetTimecode

or using the Nuget Package Manager

Install-Package DotnetTimecode

Add a reference to the library, then simply construct your objects.

Examples:

using DotnetTimecode;
using DotnetTimecode.Enums;

ITimecode foo = new Timecode(Framerate.fps30);
ITimecode bar = new Timecode(10, 00, 00, 00, Framerate.fps59_94_DF);
ITimecode baz = new Timecode("10:00:00:00", Framerate.fps24);

foo.ToString() // "00:00:00:00"
bar.AddMinutes(-61).ToString(); // "08:59:00;00"
baz.ConvertFramerate(Framerate.fps25).ToString(); // "09:36:00:00"

Constructors

Timecode(Enums.Framerate framerate);
Timecode(int hour, int minute, int second, int frame, Enums.Framerate framerate);
Timecode(string timecode, Enums.Framerate framerate);

Object methods

timecodeObj.AddHours(hours);
timecodeObj.AddMinutes(minutes);
timecodeObj.AddSeconds(seconds);
timecodeObj.AddFrames(frames);
timecodeObj.ConvertFramerate(targetFramerate);
string timecodeString = timecodeObj.ToString();
string subtitleTimecodeString = timecodeObj.ToSubtitleString();

Static methods

string timecodeString = Timecode.AddHours(timecodeString, hoursInteger);
string timecodeString = Timecode.AddMinutes(timecodeString, minutesInteger);
string timecodeString = Timecode.AddSeconds(timecodeString, secondsInteger);
string timecodeString = Timecode.AddFrames(timecodeString, framesInteger);
string timecodeString = Timecode.ConvertFramerate(timecodeString, originalFramerateEnum, targetFramerateEnum);
string timecodeString = Timecode.ConvertSMPTETimecodeToSubtitleTimecode(srtTimecodeString, framerateEnum);
string subtitleTimecodeString = Timecode.ConvertSubtitleTimecodeToSMPTETimecode(timecodeString, framerateEnum);

Object Properties

int hour = timecodeObj.Hour;
int minute = timecodeObj.Minute;
int second = timecodeObj.Second;
int frame = timecodeObj.Frame;
int totalFrames = timecodeObj.TotalFrames;
Enums.Framerate framerate = timecodeObj.Framerate;

Static Properties

string timecodeRegex = Timecode.TimecodeRegexPattern;
string subtitleTimecodeRegex = Timecode.SubtitleTimecodeRegexPattern;

Operator Overloading

ITimecode timecodeObj1 = new Timecode(10, 0, 0, 0, Enums.Framerate.fps23_976); // 10:00:00:00
ITimecode timecodeObj2 = new Timecode(1, 0, 0, 0, Enums.Framerate.fps23_976); // 01:00:00:00

timecodeObj1 + timecodeObj2;  // 11:00:00:00
timecodeObj1 - timecodeObj2;  // 09:00:00:00
timecodeObj1 < timecodeObj2;  // False
timecodeObj1 > timecodeObj2;  // True
timecodeObj1 <= timecodeObj2; // False
timecodeObj1 >= timecodeObj2; // True
timecodeObj1 == timecodeObj2; // False
timecodeObj1 != timecodeObj2; // True
