VIAN crashes when working with large image databases

[olivood]

Hi there!

Since VIAN is, at least theoretically, able to work with large image databases, I was trying to figure out the best workflow for this task. As you know, in order to work with the image database, the images must first be converted into a suitable video format. I used the image sequence of Quicktime and the program iMovie for this, which output the video as .mov or .mp4.

However, when using the iMovie-file in a new project, the program always crashes – sometimes without comment, sometimes with the phrase "Oups, there has gone something wrong....".

With the image sequence, the program works partially, but the colorimetry is very often incorrect because it is not applied for each frame.

So which program should be used to create a suitable video from a large image database?

Thank you for your help.

The creation of a video can be outsourced to ffmpeg (https://ffmpeg.org/download.html) like this: ffmpeg -r 1/5 -pattern_type glob -i '/path/to/your/image/directory/*' -vcodec libx264 example_output_movie_name.mp4

This command creates a video with all the images present in /path/to/your/image/directory/ - you can filter the files to use png files only for instance: '/path/to/your/image/directory/*.png'. Each image is shown for 5 seconds (to change it, enter the reciprocal value after the -r option). The output is saved as example_output_movie_name.mp4. Replace the mentioned parameters to fit your setup. In the long run, this command could be provided by VIAN's GUI.
