For the filter API, you can get the frame number in VideoRecord.part. You can get the video timebase in VideoRecord.tdb, which will help you interpret VideoRecord.part.
Although I have not seen the After Effects SDK yet,
I want to make a plug-in to apply video effects to get the frame back and forth based on the current frame passed from the Premiere.
Therefore, I hope that is passed from Premiere in the order of the small number of the field.
I have obtained as follows: the number of fields that are passed from Premiere.
a number of field = part ÷ sampleSize
※ "part" is from the beginning until the end of the video number (0 ~ n)
※ "sampleSize" is a number that represents the length of the field
10 = 10010 ÷ 1001
However, the number of fields that will be passed from Premiere is passed to the random.
What this specification?
How can I receive the order of the number of field?
