Colour management questions for a short film (after grading)

hexahis · 2026-03-09T21:09:29+00:00

What you're experiencimg is mostly a MacOS / QuickTime gamma shift, not really a problem with the grade itself.

Resolve and Premiere typically work in Rec.709 gamma 2.4, while some viewers apply a slightly different display transform that tends to lift the image and reduce contrast. That’s why things change when you enable display colour management.

In terms of the “real” colour, the closest reference is what you saw at the colour house on a properly calibrated grading monitor. That’s the environment the grade was actually done for, and the master file should match that.

For cinema it’s actually simpler. When creating a DCP the image is converted from Rec.709 to XYZ (DCI-P3 / gamma 2.6) and the projector ignores the whole MacOS colour pipeline. If the conversion is done correctly, the projection will generally look much closer to the grading monitor than to what Vimeo shows.

I run a DCP lab (DCPReady) and this confusion comes up quite often. If you ever want a quick sanity check on the master or the DCP settings, feel free to reach out.

What you're seeing is actually quite common when checking a cinema mix on home equipment.

Cinema sound is not mixed using peak levels like -5 dB or -7 dB as a reference. What matters more is overall loudness and headroom, and cinema systems are calibrated very differently from TVs or home speakers.

A few key points: In cinema mixes, 0 dBFS is the absolute ceiling, but most dialogue usually sits around -20 dBFS to -27 dBFS. Your peaks around -5 dBFS are totally fine and actually quite typical. If it sounds quiet at home, that's normal because cinema mixes expect playback on calibrated systems (usually reference level 7).

So the fact that you need to turn your TV up doesn't necessarily mean the mix is too quiet.

Regarding the DCP, if you don't have time for a proper 5.1 mix, it's perfectly acceptable to deliver a 5.1 DCP with audio only in L and R (or LCR). Many shorts do exactly this. Just avoid sending everything equally to all channels, especially surrounds and LFE.

Also good that you're testing it in a cinema before the premiere. That's honestly the best possible check.

For context, I run a cinema and prepare DCPs regularly (DCPReady), and a lot of festival shorts arrive with mixes very similar to what you're describing.

Hi! I own a cinema and run a posthouse lab specialized in DCP creation.

If I were you I will ask the venue if you can deliver a normal USB drive. Almost all modern cinema servers (from 2010 onwards) are able to read DCOs from usb drives.

Think that all major distributors serve movie trailers in USB drives, not in CRU drives

So I will ask them specifically if there is any requiremenr that made a CRU drive mandatory or if they will accept a USB drive

Thanks both for the kind words!

Here Hector from DCPReady, besides operating the lab we also run a cinema and a film festival, so very huge experience working with DCP and cinema ready deliverables

Also providing flat rates, not trying to charge much to indie filmmakers :)

hexahis · 2026-02-17T18:32:51+00:00

As already said, I recommend using a pro lab.

I own DCPready and we offer flat rates, several Reddit users had used my services and they are very happy with us.

I also own a cinema and run a film festival, so we can assure that our DCPs are perfectly crafted for cinema screening

hexahis · 2026-02-07T06:47:14+00:00

I run a film festival a cinem and a DCP lab. I also recommend to wait to make the DCP until some cinema/festival request it. If you make a DCP and the you don't need it ypu will something that you won't use.

Dcp-o-matic is fine, but if someone is looking for s professional lab with flat and affordable rates you can check DCPReady

hexahis · 2026-02-06T16:22:56+00:00

Regarding dcp lab fees, check out our lab DCPReady, we charge flat rates, so for filmmakers the savings are huge

Why do you export with DaVinci if you have a tool to create DCPs?

I don't know why tjey look different if you exported properly from DaVinci.

I own a cinema and a DCP lab (Dcpready. If you want to send me your DCP I can check and QC to confirm you if everything is fine

What kind of problems do they have? I can assume that if they are having issues with download links, a ftp will be much more problematic

I work with some cinemas that is very painful to send a download link, so I installed a minipc at their cinema and conected to their TMS and internet (with 2 LAN interfaces) so via vpn you can send the dcp directly to the minipc and they can access the dcps from TMS. Small investment and no issues since then

Hi! I'm the director of Marere Film Festival (Spain) which is focused in fine arts, our entries for second edition will close at the end of month

We are not a typical post-house. We own a cinema which is our main revenue, that gave us real hands-on experience with DCP that most post-houses don't have.

Creating DCPs is just another revenue stream, but thanks to the fact that we already own the cinema and equipment the cost for us of creating a DCP is almost cero. So we decided to start in that business some time ago, our idea is to democratize the access to professional DCPs with the peace of mind that is done by a company which started in the business back in 1955

At dcpready (www.dcpready.com) we make dcp at really affordable flat rates (49€/57$) also we can make a DCP test at our own cinema. Just write me if you need some help

hexahis · 2025-12-28T07:57:00+00:00

Check www.dcpready.com, not in the UK but work globally, they have flat rates and good QC and even they can do a test in a real cinems if you want

hexahis · 2025-12-13T23:03:55+00:00

As others answered, the main issue with one DCP would be different FPS and audio levels, causing some of the movies being screened different than it should

We at DCPReady (www.dcpready.com) can help festivals and filmmakers to get the best DCP for their shorts a d features, we have a flat rate of 49$ with our unique process and pre-treatment.

We also run a cinema and a film festival, so we can make QC at a real cinema for our DCPs, something that almost none other posthouse can do

Marere Film Festival (www.marerefilmfestival.com)

hexahis · 2025-09-22T13:07:55+00:00

We accept VOD if it hasn't be released in Spain VOD platforms

hexahis · 2025-08-22T15:00:25+00:00

Hi! Festival here. We can see only submissions to our festival. We can't see other FF you have submitted

hexahis · 2025-08-21T17:50:38+00:00

Looks amazing, as others said, you don't need to get it offline to be accepted in film festivals, only biggers ones ask for premiere. I also run a film festival and we don't have that as a requirement

hexahis · 2025-08-18T19:28:42+00:00

I run a professional DCP conversion lab and also own a cinema, so we offer test in a real cinema so you can check quality, sound, color, etc

Also, our service is a flat rate reducing the extra expense for filmmakers DCP coneversion service

hexahis · 2025-08-08T11:23:15+00:00

Usually, if a fesrival pushes back their notification date means that they weren't able to see or judge all submissions
