EZConvert will automatically recognize and interpret the text's color, position and alignment from the input IMSC but there would still be several options that could be configured manually:
IMSC Import Options
Using the Compatibility drop-down the user can make EZConvert interpret the input file as if it complies with the general TTML or the IMSC v.1 specifications. This might be needed because certain parameters and attributes may render differently between the two specifications. We, however, recommend using the AUTO option. This way EZConvert will check which of the specific TTML or IMSC v.1 namespaces are specified in the input file and will handle it accordingly.
The timing information section should be used to correctly identify the format of the time expression used in the Timed Text file.
Auto Recognize Timing Format - by using it EZConvert will identify whether the time is expressed as Media Time or SMPTE Timecode according to the ttp:timeBase attribute declared in the heading section of the file. If ttp:timeBase isn't present, then the time expression will be treated as if it was Media Time: ttp:timeBase="media".
If the automatic recognition cannot identify the time expressions used in the file, for example the ttp:timeBase isn't declared but at the same time you are certain the timing is expressed as SMPTE timecode, then the timing format could be selected manually:
SMPTE |
Timing is expressed as SMPTE Timecode in the format: HH:MM:SS:FF |
MEDIA |
There are couple of valid timing expressions: HH:MM:SS:FF, HH:MM:SS.NN (10 miliseconds), HH:MM:SS.NNN(miliseconds), Frames, Seconds, Miliseconds and Ticks. |
