A lot of hosts who buy an ATEM Mini ISO think of it as the thing that saves them from editing, right, you switch cameras live while you talk, you hit stop, and the episode is done, and for some shows that really is enough. But the reason the ISO models exist is that the live switch is almost never perfect, and what they record alongside it is what lets an editor turn a decent live cut into a finished episode. An ISO recording is a separate, clean recording of each camera input, isolated from whatever you happened to switch to, and the ATEM Mini Pro ISO records five streams at once, one for every camera input plus the switched program. Pixel Samy Podcast, the video podcast editing service my team runs in Dubai with human editors on every episode, edits these recordings all the time, and the files these switchers write change what we can do with an episode quite a lot.
What is an ISO recording on an ATEM Mini, and why does it matter for a podcast edit?
An ISO recording on an ATEM Mini is a clean file of each camera input recorded at the same time as the switched program, so the editor has every angle in full, not just the shots you picked live, and that matters for a podcast edit because any switch that came late, landed on the wrong person or caught someone mid blink can be fixed afterwards.
Without ISO files, right, the program recording is the only video you have, and whatever you switched to is baked in forever, which is something I see hosts regret more than almost anything else in a multi-cam show. If you were on the wide shot when your guest said the best line of the episode, that line lives on the wide shot. With ISO files, every camera kept rolling on its own track the whole time, so the close up of the guest saying that line exists, and the editor can cut to it.
The ISO models go further than video. They also record every audio source as its own track, and they save a DaVinci Resolve project file that opens your live switch as an editable timeline. And on the bigger switcher, the ATEM Mini Extreme ISO records all eight of its video inputs, which is a lot of angles for a podcast, more than most shows ever use. For the full product details, Blackmagic Design's ATEM Mini page is the place to look.
What does the DaVinci Resolve project from an ATEM Mini ISO give my editor?
The DaVinci Resolve project from an ATEM Mini ISO gives your editor the live switch as an editable timeline, with every cut you made during the recording already laid out against the clean camera files, so instead of starting from nothing, the editor starts from your switching decisions and only changes the ones that need changing.
This is the best of both worlds when it works. I trust a host's live instinct more than people expect, you know your show, you know when your guest is about to get animated, and a lot of your switches will be good ones. The timeline means we can keep those as they are and spend our time on the moments that went wrong, a late cut, a cut to the wrong camera during crosstalk, a stretch where you forgot to switch for four minutes because you were deep in the conversation, which happens to everyone.
The one weakness is that the project file only helps if it travels with the media it points to, and like any editing project, if the recording gets copied in pieces or files get renamed before upload, the links between timeline and footage break and an editor has to reconnect everything by hand. So the simplest rule is to copy the whole recording folder from the drive exactly as the switcher wrote it, without renaming or reorganising anything, and upload that folder as it is.
Should my editor keep the live switch or re-cut the episode from the ISO files?
Your editor should keep the live switch where it already follows the conversation and re-cut from the ISO files wherever it does not, because a fully fresh multi-cam cut takes longer and is not always better, while fixing the weak moments in your live switch keeps your own instincts in the episode and still gives the viewer the right face at the right time.
How much we change, right, depends on how you switched, and I decide that after watching the first ten minutes. Some hosts are naturally good at it, and on their episodes we might only fix a dozen moments in an hour. Others are concentrating on the interview, as they should be, and the live switch ends up sitting on one angle for long stretches, and on those we rebuild most of it from the ISO files. The principles we use for that rebuild, cutting on who is talking and who is reacting rather than on a timer, are the ones set out in why the cut should come from the talk, not from a clock.
There is one more reason to go back to the ISO files even on a well switched episode, and that is the clips. A vertical clip of your guest needs a tight shot of your guest, and the live program may have been on the wide shot at that exact moment, so the clean camera files are where every good clip comes from.
Can the audio from an ATEM Mini ISO recording be remixed after the show?
The audio from an ATEM Mini ISO recording can be remixed after the show, because the ISO models record every audio source as its own track alongside the program mix, so if one microphone was too loud, a guest was quiet or someone coughed over a good answer, the editor can rebalance or clean each voice separately instead of living with the live mix.
This is the part people underestimate, right. The live audio mix on a switcher is set once at the start, and conversations do not stay at the same volume for an hour. Guests lean back, hosts laugh into the microphone, someone shifts in their chair and knocks the mic stand. With separate tracks, we level each person on their own, reduce noise on the mic that needs it and leave the others alone, and cut a cough out of one track without touching the other speaker's words underneath it.
Separate tracks also save the day, right, when something goes wrong with one source, and that happens more often than hosts expect. If a microphone cable crackled for ten minutes, that crackle is only on one track, and very often the other microphones picked the person up well enough to fill the gap. On the live mix, that crackle is in everything.
What should I send my editor after recording on an ATEM Mini ISO?
After recording on an ATEM Mini ISO, send your editor the complete recording folder exactly as the switcher wrote it, with the ISO camera files, the separate audio files, the program recording and the Resolve project inside, plus any separate high quality audio recorder files and a short note on guests and anything that has to be cut.
The recording media depends on your model, ATEM Mini switchers write to USB flash disks or CFexpress cards depending on which one you own, and whichever you use, right, the thing I would watch is space, because five or more simultaneous streams fill a disk much faster than a single recording. Check before every session that there is room for the full episode plus a margin, and I would say format between sessions only after the previous episode is safely uploaded and confirmed. For the recording side of the setup, camera positions, sight lines and the angles that cut well together, the multi-cam podcast setup guide written from the editor's side covers it properly.
Switch live for the room, record ISO for the edit, and never rename a file before your editor sees it.
The mistakes I see most often with ATEM podcast recordings
That is one, coming home with only the program. If the only file from a session is the switched program, every benefit of the ISO model is gone for that episode, so before each session do a ten second test recording and check that a clean file for every camera actually appears on the drive.
Secondly, mixed frame rates and mismatched cameras, which is common on the first few episodes of a brand new ATEM setup. If your cameras are not set the same way, the ISO files will not line up as neatly and the colour will jump between angles, so the editor has to correct for it. We match colour across angles as part of a multi-cam edit, and how we keep cameras looking like one show is in podcast colour grading that matches every camera, but it is always easier when the cameras start from the same settings.
And the third one is audio sources that were never plugged into the switcher. If a guest's microphone went into a separate recorder and not into the ATEM, the switcher has no track for it, which is fine as long as you send that recorder's file too. We sync it against the camera audio, but we can only sync what you send, so a short note saying which audio lives where saves a lot of guessing.
How much does it cost to have an ATEM Mini ISO podcast edited?
Having an ATEM Mini ISO podcast edited with Pixel Samy Podcast usually falls on our Studio plan, 299 US dollars per episode up to 60 minutes, covering two to four camera angles synced and cut, colour balanced across angles, 4K delivery, lower thirds and graphics, and unlimited revisions, with longer episodes and extra camera angles beyond four scoped and priced on a call.
That extra angles point matters for ATEM Mini Extreme ISO owners, because eight recorded inputs is far more than our standard plan includes, and in my experience most podcasts use three or four of them well and the rest occasionally. So on the call we look at which angles your show really relies on, and price the edit around that. The full details of what our multi-camera podcast editing service includes are worth a look before you book, and the plan list sits in Starter and Studio pricing. Be honest with yourself for a second, how many of your cameras made it into the last episode for more than a minute?
When is the ATEM live switch good enough on its own?
The ATEM live switch is good enough on its own when the show is a simple livestream replay, an internal company update or a quick weekly check in where speed matters more than polish, and in those cases uploading the program recording with light trimming is a perfectly sensible choice that saves both time and money.
I would never tell a host to pay for a full multi-cam edit on content that does not need it, and we say as much to people who ask us. Where the ISO edit earns its keep is the show that lives on YouTube as a proper episode, gets cut into clips, and has guests whose best moments deserve the right camera. Plenty of ATEM owners go live on the day and publish the polished version later, and the extra choices that come with a stream replay, the dead air at the start, the chat overlays, the stream audio, are handled in how we turn a live stream replay into a proper episode.
The ISO files are the insurance policy
An ATEM Mini ISO lets you be a good host and a passable director at the same time, and the ISO recordings mean the director part can be fixed later by someone whose only job is to watch every face and every switch. Keep the recording folder whole, send all the audio, and let your live cut be the first draft rather than the final word. So yeah. That's my way of saying it.
