I create videos for online presentations and I intersperse slides between head and shoulder shots and screen recordings. The videos are recorded at 1920x1080 (soon to be 4K) I want to export my slides quickly as .png files at a high resolution so as to then import the slides into Adobe Premiere. The best I can do is to export them one by one (takes ages) or use the export as .html wizard which is limited to 1024x768 which is too poor a quality to use in a video.
Is there any way to do this? At the moment I have to open them with a certain other product which has a clunky interface to say the least in order to export them and then slides come out at the required resolution.
