Also keyframe handling are fiddly. Several years-long unresolved usability issues are in the forum like keyboard-selecting transitions etc.. The support forum is full of annoyances but BMD has mostly other priorities. I rarely complain as Resolve is still better than the rest for me
I had a few OFX plugins and maybe had the browser running which may have impacted RAM. Depending on how much RAM you can keep free and the amount of grading on that 8K video you may be OK with the 24GB of the M4 Pro base model but yeah - more is always better though with Apple it's painful to add more of anything .. on a budget.
It's a comparison of two CPU/iGPU combos I have on my desk with similar power draw. Those iGPUs are most power efficient for video editing as I like QuickSync from Intel.
The i5-1135G7 (17W TDP) has 2 Media Engines which I use for proxy generation in parallel for example and pretty versatile so I use it daily (64GB RAM..).
Still, I think it's a notable achievement to get 4x performance with the M4 for video at similar wattage of the i5. I don't have an M4 MacBook but I guess the M4 would perform similar to the one in the Mac mini.
I expected a fast M4 package but still was mind blown to see the video editing performance. After all these video renders run for many hours.
My 2 year old i5 laptop - even with 64GB RAM and 2x2TB SSDs upgrades - was around the same price like the base M4 Mac mini / uses similar Power. The PC surely is way more versatile with these specs and expandability.
Staying mostly in X86-land due to affordable RAM & storage, nothing I currently have comes close to the M4 performance per Watt - and now even performance per $/€ - in my video-editing use case.
There is a Github project [1] which has detailed instructions. The ancient i5-3570 only allowed 2GB ReBAR, BTW. GPU-Z says ReBAR / 4G is activated and working, Intel Arc Driver does not see it but seems to use it. Some part of the BIOS had to be manually fixed, AFAIR.
The PC was given for free, the CPU €11 yet overall I wouldn't recommend the process just for the result. It's only little benefit, if at all, though fun. On that occasion I also added some NVMe driver which works well, demonstrated for the similar Dell Optiplex [2][3]..
I just arranged a selection of 4K H.264/H.265 clips in a 2x2 grid on a 8K timeline in DaVinci Resolve.
Playback works well - up to 60fps. However, export to H.265 creates a lot of Swap. Rendering went with 15-18fps. All videos on a SMB network drive but the GPU was the bottleneck for rendering.
Swap was even around 24GB with 5 videos which I tested first. Using 4x4K it went 9 GB before stabilizing at around 2GB. No effects or grading whatsoever - plain 4K60 SDR videos.
One single SDR 4K clip renders to 8K at 25fps. Using Superscale 2x makes that 0.5-1fps.
For 8K rendering you may be better off with 32GB RAM minimum or trying the M4 Pro model maybe with 24GB. For 4K/6K editing the base 16/256 M4 Mac mini seems sufficient when all video storage will be on external drives or network.
Right now I mount up to 7 HDDs to the Mac via SMB, have some Streamdeck / Pedal and the necessary external SSDs for fast storage connected. I will see if the SMB mounts come back OK after sleep (my laptop acts as server) but the Streamdeck and HDDs wake up randomly so overall it's easier to switch everything on and off depending on usage.
The 120GB/s memory bandwidth of the unified memory helps especially with video, I guess. The M4 CPU isn't really stressed out most of the time. Only multicam and HLG conversations it maxes out.
Once I patched my old Dell T1650 BIOS for ReBAR support yet the iGPU of the i5 1135-g7 had similar GPU performance for video as the Intel Arc A380 in the desktop PC. The old PCIe3 speed limited its performance. I heard others reported a smoother replay experience with Apple silicon compared to even a RTX4090.
I get some delays when fast scrubbing through a 9 multicam 720p timeline and just 360p proxies. Still impressed compared to what I was used to. Video editors may be surprised about the performance for the price.
The Mac mini M4 performance is around 4-5x in DaVinci Resolve for me - compared to my HP laptop (i5-1135G7).
Rendering HDR video was around 12fps there on the i5 - the same project in the Mac mini gets 60fps.
The M4 10 core GPU seems on par or better with a mobile RTX3060(65W) for video tests (NR / Deflicker) so I'm also impressed about the M4's efficiency. A lot of power per Watt.
It's becoming a dedicated video rendering machine for me where all the SMB auto mounting issues with macOS seem solvable. Pretty happy so far with the base model price even in the EU. The power button placement is an annoyance for me, though.
Thanks for making the dataset available. As I recorded several city walks with multiple cameras simultaneously (usually 3-6 Osmo Pocket in 4K60) I'd like to create Gaussian splatting datasets from many such walks. What costs and hardware requirements can be expected for city-wide GS datasets like the one of Prague?
I'm wondering if I can create them myself or should donate the many TB of multicam recordings.
I guess 180 would work. There is 360/VR content on YouTube yet it seems not mainstream yet. I also have a 360° cam that I rarely use. BTW, half of all my viewers watch this type of content on TV according to the stats.
I guess subtitles, HDR and decent editing are more important for now so I'm looking for AI help in the editing part. Subtitles are already supported by GPTs
There are many YouTube channels walking through cities as the movement and sound add more to the atmosphere than street-view like experiences. I also happen to cover Prague many times like [1] in 2020 without many tourists.
One thing I started a few years is multicam walks. This means that I carry some 4-6 Osmo Pockets to actually film in several directions simultaneaously - example: Dresden [2].
The editing process is taking multiple hours so I have hundreds of unreleased recordings. If someone has a hint on AI assisted multicam editing, where to start (like better gaze prediction etc. from VR) I'd be interested - especially feeding all camera streams and let a NN decide the best camera angle and cuts to be between 4-11s?
The last time I visited Moldova was in February 2020. Recorded some walks there:
[1][2].
I also went several times since 2010. There were good connections towards Odessa which I loved during summer and Chisinau had OK flight connections.
Transnistria was more interesting back in 2018 when it was like being transported into a 1980's Russian province city. It was super cheap there actually.
Current I publish 2 walking videos per week on YouTube [1] also with a GPX Animation in the intro. For the GPX track I currently use the free GPX Animator [1] with some scripting of the CLI args.
I have experimented also with Mapbox and Remotion and could get nicer results than GPX Animator but it's not even worth the render time. Same for Google Earth Studio - it's just too slow as I often create batches of 5-6 videos per day. How long does one 20s video take to render - 4K60?
One thing I'd love to have is not just the GPX track but photos or video snippets popping up geo-located - maybe even info boxes for more than just a moving line. This could be coming from Wikipedia etc or some custom JSON data. There is potential to improve map animations but I can't see how I would recoup the cost per video. For me it would be worth less than $0.50 per video on my volume of 100+ videos per year. The web interface and video looks nice though the pricing is out of reach.
I wish you success and maybe there really is a market for premium priced GPX Animations. For me personally this could only work as a standalone app in the $30-$50 price range only.
Nice project! It may be useful to select the included places also by QRank of Wikidata [1] so notable islands will appear, despite low populations. An SQLite DB of QRank [2] was also posted here in HN a while ago.
- Some DaVinci Resolve Settings to use on SDR monitors: https://youtu.be/4izJfgRtkZE (though I upload 4K60 HDR at 37.5Mbit) which is enough for me slow content.
I'm also glad that Rambalac is back as he quit a few months ago. I've recently also started uploading 4K60 HDR content to YouTube [1] and it takes up to one week more time for them to encode than the SDR version. You can include your own LUT instead of YouTube conversion which seems to help. Here's an article and LUT [2] + a video [3] with valuable info. They allowed me getting DJI Pocket 3 HLG recordings to HDR10.
Here is another Dell story:
Bought a Inspiron 7610 (16plus w/ 32GB RAM) in November 2021:
1. laptop switches on every night at 4:28 despite contrary BIOS settings. It took me 1 month of remote service and messages to get to some undocumented reset instructions
2. In high performance profile the laptop overheats. Service finally approved after I took video. Service changes the mainboard but forgets to insert the 2nd 16GB RAM stick!
3. Had to open/photograph the laptop to prove. Forgotten 16GB RAM gets delivered but doesn't work with the device - BSOD's on boot. Clear faul of the stick as it works with only the original RAM
4. Device gets picked up yet again (unannounced), UPS tracking says delivered and -- is lost since then.
5. Refund request issued (Sept 9) but denied.
Since early August I'm trying to get a refund or replacement - for several months now with endless chat messages and some phone calls where nobody helps but waits for the "internal team". The standard apology text snippet was issued dozens of times, I've heard at least 3 times "please give us another chance" - I should wait another 24,48 or 72h but no update.
Just off a phone call with them again today I am left with an infuriating customer support when something goes wrong on their side and no laptop I paid for. I hear from other that going after them with lawyers also takes many months.
