The title at the top tells you whether this computer is licensed: it reads CrossFlow PRO once your license is active, and just CrossFlow otherwise. Unlicensed, the Main tab also shows a green TRIAL notice with how many clips per sequence the trial converts and a link to enter your license. The last four characters of your key and the name of this computer are shown in Settings & License.
That line is there so you never have to go looking. If you ever report a problem, a screenshot of CrossFlow already shows your license state, which usually saves a round of questions.
Without a license, CrossFlow converts only the first clips of each sequence, counted separately for video and for audio, so you still get picture and sound together rather than one without the other. Everything else behaves exactly as it does with a license: the same transfer of effects, keyframes, speed changes and transitions, on your own real project.
Beyond that limit, video clips are replaced on the timeline by a CrossFlow placeholder image, at their original position and length. The edit keeps its shape, so you can still see how the sequence was built. Audio beyond the limit is simply left out: a silent gap, rather than a sound you never recorded.
Nothing disappears without being told: every clip the trial did not convert is listed in the conversion details with the reason, and the conversion report opens with a line saying it was a trial and how many clips that affected.
The idea is that you can check the conversion quality on the project you actually care about, before spending anything. A trial conversion is not something you can deliver, though.
In Settings & License, paste your key into the field and click "Activate License". "Paste from Clipboard" does both steps at once.
One license activates CrossFlow on 2 computers: typically a desktop and a laptop.
If you have not bought CrossFlow yet, "Purchase" opens the CrossFlow page in your browser.
Click "Deactivate License". This frees the slot this computer was using, and CrossFlow goes back to the trial here. You can then activate your key on the other computer.
An activation belongs to the computer it was made on. Migrating to a new computer, or copying CrossFlow's settings folder over, does not bring the activation with it: CrossFlow opens as a trial there until you activate your key on it.
The license is checked again at the moment of converting. If CrossFlow cannot confirm it on that computer, the conversion runs as a trial, and its report opens with a line saying the license could not be confirmed. Open Settings & License to check the license is active on this computer, and write to contact@nablast.com if it is and this keeps happening.
Moving a license is limited to twice a month. That is meant to cover a new computer or a reinstall, not constant swapping between more computers than the license allows. If you genuinely need more, write to contact@nablast.com: it is not a problem, it just needs a human.
You cannot deactivate a computer you no longer have. Under the buttons, "Release all computers on this license" frees every slot at once. Then activate your key again on the computer you are actually using.
This is limited to once a month, so keep it for the case it is meant for rather than as a way to move between computers.
CrossFlow does not need a connection to convert. It checks your license again about once a week, and if it cannot reach the internet it simply keeps working and tries again later, for up to a month. An editing suite with no network access stays perfectly usable.
If a whole month goes by with no successful check, CrossFlow falls back to the trial until the next time it can reach the internet. Nothing is lost: reconnect, reopen CrossFlow, and your license comes back on its own.
