# Training a Project

### Why do I need to upload a minimum of 30 images?

For best results during training! The training processes work better with more data (in our case, images), so any less than 30 might just mean getting the exact same image back! We want you to have both exciting experiments, as well as a good amount of resulting images to look at and review.

### Can I upload a video or GIF to Playform?

Currently, Playform only accepts JPGs and PNGs, but we’re definitely looking to include that functionality in the future!

### How do I remove a collection?

You can remove a collection from the input sets by just hovering over a collection and clicking the **X** on the top right of the collection's bounding box. Alternatively, you can click into a collection, and there will be a button for removing the collection in the border of the dialog box.
