Every element of a 2D animation — characters, environments, icons, typography, color — should feel as though it belongs to the same designed world. The color palette should be consistent throughout. The illustration style should not shift between scenes. The typography should follow the same system in every frame. The motion style — easing, timing, transition approach — should feel uniform rather than improvised.
Visual inconsistency is one of the clearest signals of a studio working without adequate art direction, or a project that was produced under time pressure that compromised the design review process. Inconsistency breaks the viewer’s immersion in the content and creates a subliminal impression of a brand that does not have its act together. For brands investing in animation to build credibility, visual inconsistency in the animation is directly counterproductive.
5. Secondary Animation That Adds Depth
Secondary animation refers to the supporting movement of elements that are not the primary focus of the scene: the slight sway of a character’s hair as they turn their head, the bounce of objects when they settle, the subtle idle breathing motion of a character waiting to speak. These elements are invisible when they are done well — they simply make the animation feel alive rather than mechanical. They are glaringly absent when they are not included.
Secondary animation is one of the most reliable signals of production quality and animator skill, because it requires an understanding of how real physical systems behave and the ability to translate that understanding into deliberate motion decisions. Template-based and low-budget animation productions consistently omit secondary animation because it is time-consuming and requires craft that automated tools cannot replicate. Its presence in an animation reliably indicates a studio with experienced animators who care about quality beyond the primary motion.
6. Sound Design That Completes the Picture
An animation viewed without sound is like a room with no furniture: the space is there, but it does not feel inhabited. Sound design — the combination of music, voiceover, and sound effects — does not simply accompany a 2D animation. It determines the emotional experience of watching it.
The music bed sets the emotional register of the entire piece and primes the viewer’s emotional state before a word is spoken. Sound effects anchor specific visual moments — the click of a button, the arrival of a character on screen, the transition between scenes — and create a sense of physical reality in an otherwise flat visual world. The voiceover, when present, is the primary vehicle of meaning and must match the tone, pace, and personality of the brand with precision. An animation with poor sound design — generic stock music at the wrong tempo, voiceover that sounds recorded in a bathroom, sound effects applied arbitrarily — undermines visual quality that may have been excellent.
7. Deliberate Use of Color
Color in 2D animation is not just aesthetic — it is communicative. The color palette of an animation determines its emotional temperature, its brand alignment, and its visual hierarchy. Warm colors advance and attract attention. Cool colors recede and suggest calm or professionalism. High saturation creates energy; low saturation suggests refinement. The relationship between colors — their contrast, their proportions, their dominant and accent roles — determines whether a composition feels balanced or chaotic, premium or generic.
Good 2D animation uses color with intention: the most important element in any frame is given the highest color contrast or the most saturated tone to draw the eye. The color palette is consistent with the brand’s existing visual identity so the animation feels like a native brand expression. Accent colors are used sparingly enough that they retain emphasis value. And the palette is restrained enough — typically three to five primary colors — to create coherence rather than visual noise.
8. Clear Visual Hierarchy in Every Frame
A well-composed animation frame communicates a clear visual hierarchy: the viewer’s eye lands on the most important element first, then moves to supporting elements in a logical sequence, then exits the frame having absorbed the intended information. This hierarchy is created through a combination of size, color contrast, placement, and motion — the elements that are largest, brightest, most centrally placed, or moving attract attention first.
Poorly composed animation frames distribute visual attention democratically, treating all elements as equally important. The result is frames where the viewer does not know where to look, information is absorbed in random order, and the communication becomes muddled even if every individual element is well-designed. Composition discipline — ensuring that every frame has a clear visual anchor and a logical reading path — is one of the most transferable skills from graphic design to animation, and one of the most commonly neglected in lower-quality productions.
9. Transitions That Feel Designed, Not Default
The way an animation moves between scenes is a design decision, not a technical default. A cut, a fade, a wipe, a push, a morph, a graphic match — each transition type carries a distinct emotional quality and a different level of visual disruption. Cuts are energetic and decisive. Fades are contemplative and connecting. Morphs are magical and suggest transformation. Graphic matches create visual wit and intellectual satisfaction.
Good 2D animation uses transitions that are appropriate to the narrative and emotional context of each scene change. The transition from a problem scene to a solution scene should feel like a pivoting — a shift in energy that the transition style reinforces. The transition between two scenes of the same emotional register can be softer and less emphatic. Template-based animations use the same default transition throughout, which flattens the emotional texture of the piece and makes every scene change feel identical regardless of its narrative significance.
10. A Call to Action That Is Visually Earned
The call to action at the end of an animation is the most commercially important single moment in the piece, and it should be designed accordingly. A good CTA arrives after the viewer has been given sufficient reason to act — the problem has been established, the solution has been presented, the mechanism has been explained, the benefits have been felt. At that moment, the CTA is not a demand but an invitation, and the animation’s job is to make accepting that invitation feel like the natural next step.
The visual execution of the CTA matters as much as the language. The CTA should appear prominently on screen — large enough to read without straining, long enough on screen to be absorbed, visually differentiated from the rest of the animation so it registers as a distinct action prompt rather than just more content. The CTA frame should hold for at least three to four seconds after the voiceover delivers the call to action line, giving the viewer time to process both the audio and the visual prompt simultaneously.
The ten qualities above are not a checklist to be applied mechanically. They are a set of craft principles that experienced animators apply as a matter of instinct, developed through years of practice. The best way to assess whether a studio operates at this level is to ask them to talk you through a piece in their portfolio against these criteria. Their answer will tell you everything.
2D Animation Studio applies all ten of these principles on every project — because good animation is not about meeting a minimum standard. It is about producing work that does its job with craft, precision, and genuine creative quality. Get in touch to discuss what that looks like for your brand.
Frequently Asked Questions: What Makes 2D Animation Good?
Q1: How do I evaluate animation quality when reviewing a studio’s portfolio?
Evaluate a portfolio across four dimensions. First, watch each piece with the sound off — does the visual communication still hold? Good animation communicates clearly even without audio. Second, watch it again at normal speed and ask: does it hold your attention throughout, or do you find yourself losing focus? Third, after watching, close your eyes and try to recall a specific visual moment — good animation creates memorable images. Fourth, check for the subtle quality markers: does secondary animation make elements feel alive? Are transitions deliberate or default? Is the color palette consistent throughout? Are there frames where you feel uncertain where to look? These tests, applied consistently across a portfolio, will reveal the quality ceiling and the quality floor of a studio’s work far more accurately than simply responding to the most impressive piece in the reel.
Q2: Can I improve the quality of a 2D animation after it has been delivered?
The short answer is: some things, yes — others, no. Audio elements — music, voiceover, sound effects — can typically be replaced or remixed without requiring changes to the visual animation, which means a video with good visuals and poor audio can be improved relatively efficiently. Textual elements — on-screen copy, titles, CTAs — can often be updated if the source files are available. Significant visual changes — reanimated scenes, redesigned characters, altered compositions — require reopening the source project file and performing new animation work, which is a production undertaking comparable to the original project at the affected scene level. This is why investing in quality at every approval stage during production is more cost-effective than attempting to improve a delivered animation after the fact.
Q3: What separates a $3,000 animation from a $15,000 animation?
The difference is primarily in four areas: art direction quality, animation craft, sound design, and process rigor. A $3,000 animation typically uses a simplified illustration style with limited asset variety, basic rigging with standard motion, stock music and a decent voiceover, and a streamlined production process with limited revision rounds. A $15,000 animation typically involves a custom illustration style developed specifically for the brand, experienced animators applying deliberate timing and secondary animation, bespoke sound design with custom or premium music, a full discovery and strategy phase, and a thorough revision process at each production stage. The visual gap between these two tiers is significant and immediately apparent to a viewer with a reference point. The gap in strategic effectiveness — in how clearly the animation communicates and how strongly it converts — is often even larger, because the higher-investment production includes more robust script development and creative direction.
Q4: Why does the same animation look different across different screens and platforms?
2D animations are rendered as video files that are then compressed and displayed by the platform or device playing them. Different platforms apply different compression algorithms, which can affect color saturation, fine detail, and motion smoothness. An animation that looks perfect in the original rendered file may look slightly different when played through YouTube compression, Instagram’s video processing, or a web browser’s video player. Colors may appear slightly different on a mobile OLED screen versus a desktop LCD monitor. These variations are expected and are minimized through proper export settings — using the right file format, color profile, and bitrate for each platform’s specifications. A professional animation studio will deliver platform-optimized versions or provide guidance on export settings for each distribution channel.
Q5: Is there a way to assess animation quality before committing to a studio?
Yes. The most reliable pre-commitment quality assessment involves three steps. First, request a portfolio review conversation — ask the studio to walk you through two or three pieces from their portfolio and explain the creative decisions behind them. Studios that can articulate their craft decisions demonstrate a level of intentionality that correlates with quality output. Second, ask to speak with a recent client who had a project similar to yours in scope and industry. Ask that client specifically about the quality of the studio’s in-production communication and their own experience of the review and revision process. Third, if the project scope justifies it, consider commissioning a paid test deliverable — a style frame or a 10-second animation test — before committing to the full project. Most professional studios will agree to this on reasonable terms and it provides direct evidence of current production quality at zero ambiguity.
Q6: How important is animation quality for a brand that is just starting out?
Animation quality matters more for new brands than for established ones, not less. An established brand has existing recognition, trust, and credibility to draw on when a viewer encounters a piece of their content. A new brand has none of these things — every piece of content it produces is also an advertisement for the brand’s quality standards. A poorly produced animation says something very specific about a new brand: that it does not yet operate at a professional standard, or that it is prioritizing cost over quality in a context where quality signals matter. For new brands where the animation will appear on the homepage, in paid media, or in investor presentations, the quality of that animation is inseparable from the quality signal the brand is sending. The investment in getting it right at the outset is almost always more cost-effective than the reputational cost of getting it wrong.
