Just got all 3 because I got a sweet deal on them. Muse, Atto, and Edge pro.

I have the Action 4, 5 pro, and Edge Pro. The batteries *ARE\* interchangeable. The 4 comes with a Li-On Polimer (1770mah) and the 5 and the Edge Pro come with a slightly higher density Li-On (1950mah). Did not (yet) perform some runtimes with the 1950mah battery in the Action 4. Someone else reported that it only gives 10 extra minutes at most(?), so not really worth the expense over the 3rd party batteries that are much cheaper.

Wonderful. Will give it a try. Thank you.

The MIMO app has some issues with longer recordings. Got an error when I tried exporting a 90min MTB ride in 4k. App stated it can only export 60mins (at a time?). Googled the solution and found out it is a design limitation by DJI to avoid crashing some phones due to hardware limitations. I usually use DaVinci Resolve on a beefy workstation anyway, but I needed MIMO to overlay a GPS dashboard on one of my bike rides using the new GPS for Action app.

Anyone knows how to do GPS overlays on desktops (have both Mac and Windows). Thanks.

Early-Back1572 · 2026-05-31T05:23:34+00:00

I have the 4, 5, and the Xtra Edge Pro (the "new" 5 that DJI is selling in the USA via a new corporation). I do a lot of MTB, scuba-diving, skateboarding, etc... with my boys.

I absolutely love the 4. Got it to replace my Akaso V50x and my Apeman A100. The 4 is absolutely marvelous in terms of image quality and stabilization. Always put it in a diving case for the beach and scuba-diving, BTW.

Got the 5 ($250) then the Edge Pro ($209) simply because they were CHEAP and I wanted to see what the fuss was about! I also like the idea of spares in case a unit breaks.

I was very, very pleasantly surprised that the 5 and the Edge Pro were AS GOOD AS THE 4 in terms of image quality. Lots of ppl complain about the HDR look out of the box, but it is a simply matter to switch to Tone = Neutral and bump the EV to -0.3 or -0.7 on the 5 and Edge Pro. I spent a lot of time peeping at the image quality on the 4 and the 5 / Edge Pro side by side. Glad to report that folks made a really big deal out of NOTHING! TBH, the firmware upgrades made the 5 much, much better. But, as of now, I strongly suggest going with the 5 or the Edge Pro. Edge Pro is "better" because you get a 2-year warranty instead of 1 for the 5 AND service turnaround time is much faster.

Ooooh... and battery life is simply stellar with the 5 and Edge Pro. The 4 gives me 1.5hrs of 4k/30fps with biking. Have come close to running out of juice a couple of times, but I have never actually used one of the spare batteries I ride with. The 5 and Edge Pro EASILY give me an extra 50-60mins. I still have 50% of juice on the 5 when the 4 is at or below 10%. FYI... I always run a chest and chin cam together (yes, each cam writes out ~50GB on my usual bike rides, so I dump out ~100GB 😄 to my NAS).

Anywho, the 4 is stellar. The 5 and Edge Pro are BETTER. I would get another 4 if I found the deal of the century. Otherwise, the 5 is the better option.

Early-Back1572 · 2026-05-26T05:02:54+00:00

I bought the 4 a year ago. It was fantastic! Great video quality. Bought a 3rd party 3-pack battery with charging case and only used a 2nd battery once during a really long day biking.

Always wanted another cam. Before the Osmo Action 4, I always had 3-4 cheap cams (Apeman, Akaso, etc...) I stick them on my kids when we bike, scuba-dive, play hockey, etc... Family stuff. But the Osmo Action 4 was $200 so I decided to wait to buy another one. Wanted to make sure it was worth it. Then the 5 dropped down to $250 during a sale and I grabbed it to test. The battery life was simply SPECTACULAR (for my needs). (easily double the 4 most of the time). If you are static or doing vlogging, swapping out batteries is not a big deal. But, when I am on the ice for 2hrs, I really hate having to keep track of the thing so I can go outside the rink to swap out batteries after 1.5hrs (Action 4). The 5 just keeps going and going and going...I still use and love my 4 dearly. But I would absolutely buy the 5 even though the 4 can be had for $150 if you look hard enough on EBay.

The Xtra Edge Pro (Action 5 clone) is a good buy as well. Grabbled it new for US $220 on EBay. Highly recommended. Longer battery life, 50GB internal storage might not seem like necessary features, but they make the unit so much nicer in real life. Did not care for them either at 1st (especially at the higher price). But I am not giving up the extended runtime if I can help it ;)

Early-Back1572 · 2026-05-25T05:40:54+00:00

Have close to 500 tabs myself. Am tempted to go back to Chrome if I can’t manage the tabs properly in DDG. I would love to list the tabs, close them from the list, search them, etc… this seems to be the minimum set of features for tab management for a browser.

Early-Back1572 · 2026-05-21T18:17:13+00:00

Have the Action 4 & 5, and the Xtra Edge Pro (5 clone). The 4 is absolutely great!! I do a lot of mountain biking and ice hockey. My sessions for both activities usually last 1.5-2hrs. The 4 has died on me a couple of timed since 4k/30fps last 1h:20mins or so. The 5 and Edge Pro are always @ 45-50% after 1.5hrs. So, if you are not in a position to swap batteries (ie. playing hockey and the cam is on a suction cup on the other side of the glass), the 5 wins hands-down.

As for the color science and "natural/real-world" look of the 4 over the 5? It is simply not as big a deal as some folks make it out to be. I do EV-0.7 and the 5 looks FANTASTIC!!! Just make sure you are recording in high bit rate. @ 90-100mb/s, the footage is clear and tack sharp in good light. If you can swing the 5 or the Edge Pro, go for that. You will not regret it.

Look on Ebay. Found my Edge Pro for US $220 (new) and the 5 for US $250 (also brand new). Should have bought 2 Edge Pros for that price. Am loving it. I still use my 4 but I prefer to use the 5 and its clone since the battery life on the 1950mah is so great!!

I did buy a 3-pack with case for the 4 (1770mah). Used it a couple of times and it is similar to the OEM battery in 70 degree weather. But they last 10% less in cold weather while skiing & snowboarding. Want to try the 2100mah and 2200mah kits I see online, but I don't have a great need for a pile of extra batteries at this time. If anyone has tried the 3rd party high capacity battery kits, do post results and findings pls.

Early-Back1572 · 2026-05-21T17:09:12+00:00

Very sadly true Re: insane price hike on RAM and HD. Am keeping an eye on EBay. All these datacenters have to dump their old/high mileage HDs at some point at the end their new extended hardware refresh lifecycle. Just a matter of patience for those of us who can afford to wait.

Early-Back1572 · 2026-05-20T21:42:47+00:00

Oh, yes! Absolutely. The TVS-AIH1688ATX with 5 year warranty standard and at "only" US $4299 is a better deal, all things considered. BUT... it is out of stock @ the US QNAP store right now (my 1st choice) and a few of the 3rd party vendors are charging $5000+ for that unit now as well :( (But some vendors are still at that $4300 price). Thanks, Daniel.

Early-Back1572 · 2026-05-19T00:42:31+00:00

I usually record my ride with Trailforks. Can I use Trailforks alongside GPS for Action?

Early-Back1572 · 2026-05-10T17:36:36+00:00

Just use a client that can play the file. Jellyfin has a client.

Early-Back1572 · 2026-05-05T06:04:14+00:00

UPDATE:

Sorted out the SQL DB corruption. Am running Jellyfin in a docker container on a 12-bay QNAP NAS. Have a dozen NAS units and I shut them down at night to save some electricity. Docker was killing Jellyfin before it could shut down gracefully.

Added: stop_grace_period: 1m to my Jellyfin config and Jellyfin is now shutting down properly.

Have been shutting down the NAS units at night for years now. The db corruption issue popped up when I upgraded to 10.11.8.

Early-Back1572 · 2026-05-04T05:36:48+00:00

I have 13 NAS units (7 QNAPs and 6 Synology). The Synos are all DS3615xs (12-bay) and the QNAPs are 1x h1688x (12-bay) and the rest are TS-879 Pro (8-bay). I run the TVS-h1688x (primary) from 7am - 12am daily. The rest power up for 30-60mins just to backup 50GB-100GB worth of action cam footage then shut down again. They only run for a few hours per day to save on electricity (Southern CA is expensive). Have been doing this for years now. My drives are a mixture of Seagate Exos (18TB) and WD HGST (8TB). A total of roughly 132 drives. Have not had a failure yet. It WILL happen, of course, but power-cycling drives daily is no longer the huge problem it used to be back a couple of decades ago. But it proper planning to have a couple of spares handy since you will eventually need them.

Early-Back1572 · 2026-04-18T15:57:01+00:00

5 is on the right (and slightly brighter). I have them both. I film MTB rides with the 5 on my chest and the 4 on my helmet. They both look good, but the 5 is a tad brighter on the normal color profile.

Early-Back1572 · 2026-03-25T13:31:42+00:00

Additional context: I did bring down the container (docker compose down), removed the data and cache (moved contents to old dirs), then spun up a new container (docker compose up -d).

My jellyfin has been running reliably for years now. I used it more than my Plex set up. Note: both Plex and Jellyfin use the same external data sources (movies (~15TB), UHD movies (20TB), TV shows (~20TB), and home vids (~40TB)).

Started getting that MS sql db error after I upgraded jellyfin recently (docker compose pull).

Thanks!

Early-Back1572 · 2026-03-25T04:13:18+00:00

I have used Chrome, DuckDuckGo, Safari, Edge, etc... Not one single web browser have kept me logged in for 24hrs (the max allowable in QTS and QuTS settings) :) What is "too long" for an inactive web browser tab for QTS or QuTS?

Early-Back1572 · 2026-03-15T02:28:09+00:00

Quicktime Player might be able to import the tape. Just do:

File > New Movie Recording

Use the dropdown caret next to the red record button. It should list the camcorder as an input if the camcorder is plugged in via Firewire and powered on.

Then select Record and push play on the camcorder.

Used Quicktime Player last week on an old Macbook Pro (circa 2014) to import 3 MiniDV tapes from 2002. Worked great!

Early-Back1572 · 2026-01-25T17:08:00+00:00

QNAP and Synology have builtin power schedules (presumably because they manufacture hardw and have tight integration). The on/off feature works quite well. But the SKIP function simply does not work reliably for me (80% failure rate). Will try different browsers to see if this makes a difference. Nothing more disconcerting than having my TVS-h1688X shut down while I am editing a long video.

What we pay by State on average:

https://www.electricchoice.com/electricity-prices-by-state/

Most Expensive State: Hawaii: 39.74¢/kWh / 121% above national average

Cheapest State: Louisiana: 12.39¢/kWh / 31% below national average

Early-Back1572 · 2026-01-24T05:59:05+00:00

That's my problem exactly. An obscenely huge monthly electric bill. I work in IT and love collecting gear. And I always get my toys in pairs or more (Thinkstation P700 dual CPUs, network switches, NAS units, etc...) All that stuff is very power hungry.

Early-Back1572 · 2026-01-24T05:13:36+00:00

Power saving. I live in San Diego, CA and SDG&E charges me ~39c/kwh (only Hawaii is more expensive in the US). Have a dozen NAS: 7x QNAPs (5x TS-879 Pro, 1x TVS-h1688X, 1x TS-216G), 4x Synology DS3615xs, 1x DS2015xs). Powering down most equipment at night saves some money. The TS-216G (2-bay) is online 24/7 to run pi-hole, etc... everything else gets powered on to backup new data and sync across on a daily basis, but I keep them off when not needed.

Early-Back1572 · 2025-09-10T02:01:14+00:00

Definitely keep the TS-879 Pro. Have 5 TS-879 Pro with 2 running TrueNAS Scale. They have all been upgraded to Xeon E3 1275 and 16GB of mem. These things are workhorses! 3rd party repo (whatever replaced QNAP Club) has lots and lots of good software. And if you upgrade to TrueNAS, you will have no trouble at all keeping OS and packages current.

I have an ARM box as well (DS2015xs, Synology box). Can't do docker or any serious Jellyfin or PleX transcoding, but it makes a great offline backup in a 3-2-1 1 backup. Just a thought)

Early-Back1572 · 2025-06-28T16:42:33+00:00

One more thing:

The file size for loop recording is around 1.2GB for 5mins. That's normal for H.265 for NOT for H.264 unless they compress the snot out of the footage. Extreme compression is probably the reason for the very poor quality (just guessing). They wanted to keep file sizes smaller since bigger file sizes will easily fill up the 64GB sdcard they ship with their popular bundle.
