A campaign deadline and a folder of MOV files
You're putting together a product launch reel and your colleague just AirDropped you fifteen clips she shot on her iPhone. They're all .mov files, and the CMS your team uses only accepts MP4. The launch is tomorrow.
You don't want to install Handbrake, you can't wait for IT to push a Premiere license, and the free online converters either upload everything to a server or cap you at one file unless you pay.
You drop the whole folder onto the page. The fifteen clips line up in a queue, the tool starts on the first one, and you go grab a coffee. By the time you're back, every clip is sitting there as an MP4, and there's a single ZIP waiting for download. You upload the batch to the CMS, schedule the post, and clock out on time.
