Details Given: 1. Set of photos (let’s take 10) 2. All images have their individual caption Once we click on a button to make a video.. Requirements: 1. To make a video from selected photos 2. There should be background music from selected music (playing only one selected) 3. In a video, photos come one by one in a slideshow manner (for example- the image comes from the top, bottom, sides, cross, pop up, zooming in-out, etc. effects) 4. Individual captions for images are in the form of subtitles for the respective image Based on my google search, I think Python, Opencv, FFMPEG technologies work well. ^^this product, we want to integrate into our android app. App has photos in it.
