Option to inherit video resolution

[pixelchai]

Good work on this project.

Using the CLI, I am concatenating two video files like so

editly first_file.mp4 second_file.mp4 --out output.mp4

The input files are both 1920x1080, but the resulting video file is 640x360

Specifying the width and height in the command works, however, providing an option to automatically detect the lowest common resolution from the input files would be a good enhancement

Yea, I default to a width of 640, because with bigger resolutions it tends to take a longer time to process. I wanted the default command line to produce something relatively quickly, and if people want a higher resolution they can just add parameters.

I could find the lowest common resolution, but I'm not sure how to define lowest common, is it width multiplied by height? as in number of total pixels? Then the output aspect ratio will depend on the aspect ratio of the smallest video (in term of n pixels)

[pixelchai]

Actually, maybe you could just inherit the resolution of the first video provided

[mifi]

Yes, but I think most people don't really need full 4K resolution output, and if they do, it's easy to just specify it. I find it more important that it generates a video relatively quickly for first time users

[chapmanjacobd]

maybe one solution could be that we put --fast in all the examples so that it is fast for first time users but we could default to a compromise resolution like 720p / resolution of first input video

[mifi]

That's a good idea. I will do that

I wish width and height would still override resolution inheritance, even with fast: true, because otherwise I have no way to test that my elements are correctly positioned, other than running it with fast: false—which defeats the purpose of having a preview option. FYI I'm cropping a vertical video down to a square.

[mifi]

Maybe we could instead preserve aspect ratio with fast: true, and make sure the total number of pixels is quite low.

[mifi]

Now --fast will keep the aspect ratio, just make the video smaller (62500 pixels)
