Collectrium supports video file upload! You can upload video files to objects in the same way you would upload images:
1) While in the object detail page, Click the plus sign next to the main object image (if no image exists for that object yet, click the main block).
2) An upload prompt will appear. You can drag and drop or search for the video you would like to upload from this prompt.
3) Hit save and now your video is available in Collectrium.
Alternately you can upload the file as an attachment, however this merely stores the video. Meaning, it will not be view-able within the platform, only downloadable.
