RAM is the short-term memory your editing software uses to hold footage, effects, caches and the timeline itself. When there isn’t enough, the computer swaps data to disk, and playback stutters, scrubbing lags and exports slow down. But past a certain point, extra RAM does nothing at all. With a 64GB kit now costing close to $1,000, it pays to know where that point is.
What Adobe and Blackmagic recommend
Source: Adobe, Premiere Pro technical requirements. Blackmagic Design, DaVinci Resolve 21.1.1 readme (updated 1 October 2026), also summarised by iFilmThings. Check the vendors’ pages for the latest versions.
Official requirements are a floor, not a target. They describe what runs the software, not what keeps a busy studio editing smoothly. Note that Blackmagic’s background rendering requirement asks for 32GB on both Windows and Mac, double the Mac Fusion figure. If you leave Resolve rendering and analysing clips in the background while you cut, plan for that number rather than the minimum.
Why workstation builders recommend more
Puget Systems builds editing workstations and publishes hardware guidance based on its own testing. Its current advice is much higher than Adobe’s or Blackmagic’s. For Premiere Pro it says “we generally recommend a minimum of 64GB”, and its Resolve page gives the same resolution guideline.

Why the gap? Puget says the right amount depends on project length, codec and complexity, and that running several programs at once calls for more. Editors who keep After Effects, Photoshop and a browser open next to Premiere Pro will recognise that. A builder sizing a machine for every possible project will always aim higher than a software maker listing what runs the app.
For most studios, the right answer sits between the two. Use the official figures as the floor, Puget’s as the ceiling for heavy work, and your own measurements, explained below, to decide where you land.
How much RAM for Premiere Pro and Resolve editors really need
Source: Suggested RAM is Cut Pro Media guidance for full-resolution editing. Prices: Tom’s Hardware RAM price index, lowest current US prices (updated 22 October 2026).
Codec matters as much as resolution. Heavily compressed long-GOP footage such as H.264 and H.265 is harder to play back than intraframe codecs such as ProRes, even at the same resolution. A timeline with several such streams, effects and noise reduction will use far more memory than a simple single-camera edit.
Hardware decoding helps here. Nvidia’s RTX 50 cards added decoding for 10-bit 4:2:2 H.264 and HEVC, which Premiere Pro supports from version 25.3, according to Puget Systems, and Intel Core processors with Quick Sync also decode H.264 and HEVC in hardware. When decoding runs on dedicated hardware, playback is smoother and the processor has more headroom, though RAM still holds the frames, caches and effects.
By type of project
Resolution alone doesn’t tell the whole story. Here is how we would size memory for the kinds of projects we edit every week, assuming full-resolution editing:
- Real estate films: usually single camera plus drone, short and lightly graded. 32GB is enough for 4K, and proxies make it comfortable.
- Corporate interviews and talking heads: two cameras, simple graphics and a clean grade. 32GB works for most; 64GB helps with long interviews and many layers.
- Wedding films: long multicam ceremonies, speeches and heavy audio. 64GB is the comfortable level for 4K multicam.
- Commercials and music videos: heavy grades, noise reduction, speed ramps and effects. 96GB or more, especially with Fusion or After Effects open.
A worked example
Take a wedding editor on a 32GB PC cutting four-camera 4K multicam ceremonies shot in 10-bit HEVC. Memory sits at 95% during playback and the machine pauses when scrubbing. That editor has three choices:
- Upgrade to 64GB of DDR5: from $989 at October 2026 prices.
- Edit on proxies: free, apart from transcode time at ingest, and keeps the 32GB machine useful.
- Send out the biggest multicam jobs: a highlight film and feature film together cost $520 at Cut Pro Media’s flat rates, so the price of the RAM upgrade covers almost two complete weddings.
How to check how much RAM your projects use
Open your heaviest real project
Not a test file: your biggest multicam or most effects-heavy timeline.
Close everything else
Browsers, chat apps and cloud sync tools can use several gigabytes and skew the result.
Watch memory while you edit
On Windows, use Task Manager’s Performance tab. On a Mac, use Activity Monitor’s Memory tab and watch memory pressure. A green graph means you have room; yellow or red, with a growing swap figure, means the Mac is moving data to disk.
Play, scrub and export
If memory stays below about 80% and playback still stutters, the bottleneck is likely the graphics card, storage or codec, not RAM.
Check the graphics card too
Task Manager shows dedicated GPU memory. If video memory is full while system RAM has room, a better card may help more than extra RAM.
Check your software settings
Premiere Pro lets you set how much RAM is reserved for other apps (Settings › Memory). Make sure Premiere isn’t being starved. In Resolve, the Memory and GPU section of the system preferences shows how much memory Resolve is allowed to use.
How to upgrade RAM without wasting money
Repeat the test on two or three different projects before deciding. One unusually heavy job is a reason to use proxies for that job, not to upgrade every seat. If your tests show you really are running out of memory, these steps keep the cost down. For the wider market picture, see our guide to RAM prices in 2026.
- Top up DDR4 machines with DDR4: Tom’s Hardware’s October index lists 32GB of DDR4-3200 at $199 and 64GB at $469, against $989 for 64GB of DDR5. It advises against new DDR4 builds, but upgrading an existing one makes sense.
- Choose capacity over speed: 32GB of DDR5-6600 costs $673 against $447 for DDR5-6000. For editing, having enough memory matters far more than the speed rating.
- Buy a matched kit: adding a new pair to an old pair can cause instability or lower speeds. Check your motherboard’s supported memory list.
- Compare retailers: in the UK, NerdZap found £30–£50 gaps between retailers for identical 32GB DDR5 kits, which were selling for around £279–£329 in September 2026.
- Price the whole machine first: if the workstation also needs a new graphics card or drives, compare the total with a new build. Our workstation cost guide has current figures.
How to edit smoothly with less RAM
- Use proxies: both Premiere Pro and Resolve can create lightweight proxies on ingest. Edit on proxies, then switch to the originals for grading and export.
- Use optimised or intraframe media: converting long-GOP footage to an editing codec reduces playback strain.
- Render previews: render heavy sections in the timeline rather than playing effects live.
- Close other apps: browsers with many tabs can quietly use several gigabytes.
- Split huge projects: separate long ceremonies or feature edits into smaller sequences.
- Turn off background work while editing: Resolve 21’s background rendering wants 32GB, so on a 16GB machine, render when you’re not actively cutting.
- Outsource the outliers: if only a few projects a year need 96GB or more, sending those out costs less than buying memory you rarely use. See our upgrade vs outsource comparison.
What about Macs and unified memory?
On Apple Silicon Macs, memory is shared between the processor and graphics, so it counts for both. Blackmagic’s Mac requirements are lower than on Windows: 8GB minimum, or 16GB with Fusion, 16GB for advanced AI tools and 32GB for background rendering and analysis. In practice, editors cutting 4K multicam on a Mac usually want 36GB or more. The new M5 Max Mac Studio starts with 36GB at $2,499 and can be configured with 48GB, 64GB or 128GB; the M5 Ultra starts with 96GB at $5,499.
The big difference is that you can’t add memory to a Mac later. Whatever you choose, you’re locking in for the life of the machine, at 2026 prices. Apple also raised Mac prices on 25 June 2026, moving the base Mac Studio from $1,999 to $2,499, and MacRumors notes that memory upgrades on the new Mac Studio cost more than usual because of the shortage. If you’re unsure, size a Mac for the heaviest work you expect in the next three years, not the work you do today.
Common RAM mistakes editors make
- Buying RAM to fix a GPU problem: if video memory is full or AI tools are slow, system RAM won’t help. Our guide to GPU prices and what editors need covers graphics cards.
- Judging by a test clip: a single short clip never uses memory the way a real multicam wedding or feature edit does.
- Ignoring the codec: 10-bit 4:2:2 HEVC on a machine without hardware decoding can stutter with plenty of free RAM.
- Buying 128GB for the occasional 8K job: at current prices that memory sits idle most of the year.
- Under-specifying a Mac: 36GB is fine for HD and light 4K, but it can’t be upgraded if your work grows.
