I found a method on internet to use avconv
to make a video from images, but the quality is very poor. I set the resolution but it didn't help.
avconv -i "franc%04d.jpg" -r 30 -s:v 1280x720 a.mkv
How can I choose the image compression and set the quality to best?
You can do that with ffmpeg and imagemagic. Install them if they are not installed on your PC.
Do these steps in your terminal:
1. Create a directory for trying this solution, you better make a duplicate copy of the videos before trying this.
2. Copy all of your images to that directory
temp
you have created.3. Set the resolution of your images.
4. Convert them to be get morphed for soft transitions and and make them a mp4 video.
ffmpeg is not in the repositories for Ubuntu 14.04, but is in 15.04!
