As title say, is tedius to always copy and paste videos and expecally gif to loop them.
In Vegas there was this cool solution that when you keep dragging a video to the end of the clip it will automatically create a copy besidethat and loop it back from the start. It was such a time saver in certain situation. When i have to import a gif and loop it inside a premiere pro the only solution that i found is that you have copy and paste it like 50 times if i want it for a longer duration, then nest it if i want to increase speed of the clip and so on.
Pretty tedius labor when you can have better solutions for that.
