video compression in story line
I wonder to know how the video is encoded in story line for MP4
When adjusting the video quality in story line from lower rate to higher quality (5),
how vary the following parameters:
n : gap between intra image
and m parameters gap between bidirectionnal image
cbr (constant bit rate) or vbr (variable bit rate)
number of pass: 1 or 2 ?
And I have a second question: MP4 video is imported in storyline
What is your recommmendation about the imported MP4
60 image/sec or 50 image/sec
interlaced or Progressive
Size in term of pixels or lines
Is it better to import the highest quality and let the storyline encoder makes the job to reduce quality and rate
or do you recommend an average flow rate.
Thank you in advance and best regards
