Hello,

How do I add a 3-second duration screen to a video with brief description of the contents?

As I see it, I can use two sequentially named videos, viz.,

Video_1.mp4 – a single frame Video (duration 3 seconds) with intro text and
Video_2.mp4 – the original video as the other.

In this method, video conversion and audio-video sync will not be necessary.

I use Vidcoder, VideoToVideo, etc.

Any suggestion is welcome.
