  1. I am using Movie Thumbnailer https://gitlab.com/movie_thumbnailer/qmtn/-/wikis/home on Linux. This is a GUI for the CLI "mtn", which I have also successfully installed. https://gitlab.com/movie_thumbnailer/mtn/-/wikis/home

    There is a screenshot showing on https://gitlab.com/movie_thumbnailer/qmtn/-/wikis/home . It shows the screen where you make changes. I have tried to make changes at least 20 times but I can't seem to get what I want.

    I would like to know how to:
    1) make a thumbbnail every 10 seconds (6 per minute) - it doesn't seem to do it every 10 seconds when I change settings.
    2) make the size of the image(s) as big as it needs to be to make all thumbnails in the movie. It doesn't seem to 'grow'.

    I would really love some help!

  3. I have read the usage tips. One of the reasons I went with the GUI was so I don't have to do commandline. However, I have not been able to successfully do what I want with that configuration screen. If you have successfully made thumbnails every 10 seconds, please share your settings.

  4. The screenshot you uploaded seems to indicate it works like the thumbnail generator in MPC-HC or SMPlayer. You have to specify the number of rows and columns and there needs to be enough of them to give you the duration between thumbnails you want. I assume the "Step" setting in the screenshot must be limited by the specified number of rows and columns.

    I'm on Linux so I used SMPlayer. The movie I tried it with had a duration of 1:41:18 or 6078 seconds. Divide that by 10 and you get 607.8 images, so I specified 10 columns and 61 rows with a maximum width of 1280 for the image, so the steps weren't always 10 seconds apart, but SMPlayer doesn't have a step option to ensure they're spaced exactly a certain distance apart (every so often it was only nine seconds). It makes for a big single image though, so you might need to use the options for setting start and end points to create multiple thumbnail images instead of a single large one. You could increase the maximum width to make the images larger or reduce the number of columns. If I'd made it 5 columns I'd have needed 122 rows (although SMPlayer seems to have a maximum of 99).

    I re-saved the original PNG created by SMPlayer as a jpeg to reduce the file size.

    Hi, I am working on a similar program, I think it can do something similar to what you want. The program works based on the number of columns and rows that is configured, but you can specify the calculation needed to get them based on the duration. But due to the rounding of the calculations it will never be exactly 10 seconds. It is a rather advanced but possible configuration.

    The program is command line, but it also has a GUI, although the advanced configuration is not yet complete in the GUI. The program has many options and some of them are quite complicated, if you are interested I can help you to configure it.
