Side by Side Color Grade Comparison for Client Approvals Without Rendering Twice
A side by side color grade comparison helps clients make faster, clearer approval decisions without requiring the colorist to render two full outputs for every review round.
Color approval is where client feedback often becomes its most painful. The problem is usually not that clients have bad taste. It is that they are comparing something they cannot describe to something they are seeing for the first time, and they do not have the vocabulary to say what they want changed.
A side by side color grade comparison changes that dynamic. When a client can see two grades next to each other in the same session, they can point to what they prefer and what they do not. "That one, but with the warmth from this one." That is actionable. "Make it pop more" is not.
The challenge is getting to that comparison without making the colorist render two full outputs every time a client wants to compare options.
Why Colorists Resist Multiple Renders
Rendering is expensive in time, especially at high resolution. A two-minute commercial spot in 4K can take 30 to 45 minutes to export, depending on the pipeline. Asking a colorist to render two or three grade options every time a client wants to compare is asking them to burn hours on logistics instead of craft. A video proofing workflow built for this makes all the difference.
And honestly, if you are sending three different rendered exports to a client and asking them to compare by switching between browser tabs or Finder windows, you are not actually giving them a useful comparison. You are giving them three separate experiences that their brain cannot accurately hold simultaneously.
The goal is a real side by side, in one view, without requiring double the rendering work.
A client who can see both grades simultaneously makes a faster and more accurate decision than one who has to remember what grade A looked like while watching grade B.

How to Set Up a Comparison Without Double Rendering
There are a few approaches that work, depending on your pipeline.
Option 1: Grade a split-screen in the NLE or DaVinci. This works well for still comparisons. You comp two versions of a shot side by side in a sequence and export a single video file. The client sees both grades in one frame. This is fast to set up and requires only one render. The limitation is that it works best for a single shot or a short selection, not a full timeline comparison.
Option 2: Upload two versions to a review platform with compare mode. This is the most practical approach for full timeline comparison during client approval. You upload both graded versions and use the platform's side-by-side or A/B compare mode. In PlayPause, the version comparison tool lets you stack versions in a single project and toggle between them at the same timecode. Clients can scrub through both versions simultaneously and leave timecoded notes on whichever frame they are commenting on.
This requires two renders, but it does not require two separate review sessions or two separate links. The comparison happens in one shared space, and the approval is logged to the version the client selects.
Option 3: Gallery stills comparison before committing to a full render. For early color direction decisions, you can export gallery stills from DaVinci Resolve and share them in a review link. Clients give feedback on still frames before the full timeline render happens. This narrows the options and saves the full render for the version the client has indicated they prefer.
Structuring the Client Approval Session
The way you structure the comparison session determines how useful the feedback is. A few things that make a real difference:
Pick the comparison shots deliberately. Do not show the client the entire timeline in two versions unless the grade is very close to final. Pick two or three hero shots that best represent the grade direction and build the comparison around those. When clients are evaluating a full timeline side by side, they get overwhelmed. When they are evaluating three representative shots, they can give you a clear preference.
Give clients a frame for the decision. Tell them what you want them to react to. "We want to know whether you prefer the cooler, more desaturated look in option A or the warmer, more contrast-heavy look in option B. Both are technically correct, so this is purely a creative preference." That framing reduces the chance that the client will try to redesign the grade rather than choosing between two options.
Set a decision deadline. Color approval rounds have a downstream impact. The colorist cannot finish the grade until the direction is confirmed. Set a clear deadline: "We need a color direction decision by Thursday to stay on the delivery timeline."
What to Do When the Client Wants a Third Option
This is the moment that can spiral a color grade into an expensive loop. The client cannot decide between A and B and asks for a C.
My approach: do not immediately say yes. Ask what specifically is missing from A and B. Often a client who wants a third option is actually describing a hybrid of the two they already have. "Option A, but with the skin tone handling from option B" is not a third grade. That is a refinement of A, which is much faster to produce.
If they genuinely need a third direction, that is a scope conversation. It is an additional color direction, and the colorist's time for rendering and revising should be covered. Be upfront: "Creating a third grade option is outside the original scope. I can get you a quote for that, or we can work to refine one of the existing options into what you are looking for."

Keeping the Colorist's Timeline Intact
The whole point of a structured comparison process is protecting the colorist's time and keeping the delivery timeline intact. For more on how to structure the overall approval loop, see how to reduce the number of feedback rounds without rushing the client. Every unstructured comparison session or late-added option request costs real hours.
A few practices that protect the colorist:
- Do not send raw comparison files to the client without going through the producer first
- Never promise a "quick look at a third option" without checking with the colorist
- Make sure feedback from the comparison session goes to the colorist as a consolidated brief, not as a raw export of client comments
For how that handoff works in practice, the post on colorist feedback workflow that keeps directors and DPs on the same page has the role-specific detail.
The client does not need more time. They need a better way to see both options at once.
Making Color Approval a Non-Event
The best color approval sessions I have seen are almost boring. The client sees two options, has a clear preference, expresses it in specific terms, and the colorist wraps the grade. The whole thing takes one session.
That only happens when you set the session up correctly. Right comparison shots, clear framing, timecoded feedback, and a platform that makes the A/B comparison feel natural rather than technical. If you are running multiple versions in post at the same time, the post on preventing version confusion during the color grading approval stage covers the broader version management side.
