MediaFlowSwift vs OffShoot: Which One Fits Your Workflow?
Both prove a copy is good with a checksum, not just a finished drag. OffShoot is built for fast transfers from many sources to many destinations at once. Its Pro edition adds S3 and scripting. MediaFlowSwift is built for what happens after the copy: reviewing, organizing, archiving and publishing the footage.
What does each app actually verify?
MediaFlowSwift computes a SHA-256 checksum of every file it imports from a card, drive or folder. It then reads the whole copy back from the drive and compares the two. SHA-256 is the hash function set out in the US government's Secure Hash Standard. Right before Clear Card deletes anything from the card, it checks again from scratch.
OffShoot performs verified transfers using checksums to and from any type of storage medium. It can also write an MHL file that lists what it checked. That format is kept by the American Society of Cinematographers' ASC Media Hash List project. OffShoot's pricing page lists ASC MHL among the Pro edition's features. MediaFlowSwift keeps its record of what was checked inside the project, not as a separate MHL file.
What does OffShoot do better?
OffShoot multiplies sources by destinations. Point it at three cards and two drives, and one click adds all six transfers. That matters on a set with a dedicated DIT station. Its Pro edition adds S3 transfers, scripting and APIs, and Codex copy engines for cameras such as the Alexa 35. It also has Connect, a free browser companion for watching transfers, and it runs on Windows as well as Mac.
What does MediaFlowSwift do better?
OffShoot centres on moving and checking files. Its presets can rename files and sort them into new folders. MediaFlowSwift keeps going after the copy.
When you organize, it files each clip into Category and Camera folders. It offers frame-accurate review with star ratings and tags. It archives to numbered drives and records what went where.
It also writes PDF, HTML and CSV reports for an editor. Studio Pro drafts YouTube titles, descriptions, chapters and tags from the finished video. It can set them on the upload for you.
What does one 128 GB card look like in each?
Take a full 128 GB card and a setup that moves data at 250 MB/s end to end. One full pass over the card is 128,000 MB ÷ 250 MB/s = 512 seconds, about 8.5 minutes. That is arithmetic, not a benchmark. The real figure depends on the slowest of the card, the reader, the cable and the drive.
- MediaFlowSwift, import: one pass to copy, one pass to read the copy back. About 17 minutes.
- MediaFlowSwift, organize: if the import landed on the destination drive, the clips are renamed into place in seconds. Otherwise they are copied and checked again.
- MediaFlowSwift, Clear Card: it reads the card files and the organized copies in full before deleting. That is up to two more passes, about 17 minutes.
- OffShoot, one card to two drives: one source times two destinations is two transfers in one job. You get both copies from a single run.
MediaFlowSwift makes its second copy later, when you archive the project to another drive. See how to keep two checked copies of a card.
What are the limits on each side?
- MediaFlowSwift runs only on a Mac with Apple silicon and macOS 14 or later. OffShoot runs on macOS and Windows.
- MediaFlowSwift copies to drives and network shares, not to S3 or other cloud storage.
- MediaFlowSwift writes no MHL file. If a client or studio asks for ASC MHL, OffShoot Pro covers it.
- MediaFlowSwift clears one card at a time. On a card laid out by the camera, such as a Sony card, it deletes nothing and tells you when the card is safe to format in the camera.
- OffShoot's own feature list has no clip review with star ratings, no record of numbered archive drives and no YouTube publishing.
