-Presets restart each time we start the app. Also Max size is set on 3, while 4chan actually authorize until 4. Setting it to 3 uselessly reduce the quality. If anything set it on 4, and make it using the last preset used when you start it.
-Also, we have to precise a lenght, but we don't always want to cut the video. Most of the time we don't want to. Just make a box to check, "full" or not, and if not, enter a lenght. And make the "full" option checked when you start the app. In the current state, we have to check the lenght of the video we're converting each time, and enter the number manually, a lot of time wasted.
-Also, precise the unites of each line. Max size is in megabytes and lenght in seconds, but I had to try to know. It's better if it's precised.
-Redact some some quick tutorial ?
