Setting Up Your First Project: File Formats, Resolutions, and Inputs

Before generating your first AI-assisted video, it’s crucial to prepare your source materials in compatible formats. Video generation tools often require specific input types to ensure smooth processing and high-quality output. These inputs may include still images, audio tracks, text prompts, and video clips.

Understanding the technical requirements–such as resolution settings, supported file formats, and input compatibility–helps avoid common rendering issues and ensures that your video meets platform or client standards.

Essential Input Specifications

• Images: PNG or JPG, minimum 720p resolution recommended
• Audio: MP3 or WAV, 44.1 kHz for optimal sync
• Text Prompts: UTF-8 encoded plain text or JSON format
• Video Clips: MP4 (H.264 codec), max 4K resolution

Tip: Mixing input types (e.g., pairing a text script with still images and audio) allows more dynamic and context-aware generation.

Input Type	Preferred Format	Max Resolution
Video	MP4 (H.264)	3840×2160 (4K)
Image	PNG, JPG	1920×1080 (Full HD)
Audio	MP3, WAV	–
Text	TXT, JSON	–

1. Organize input files into separate folders (e.g., /audio, /images, /scripts)
2. Verify each file matches the supported format and resolution
3. Import inputs into the video generation interface following tool-specific guidelines

Important: Upscaling low-resolution assets artificially may degrade output quality. Always source high-res media when possible.

Script Writing Tips for Natural-Sounding AI Narration

To create lifelike narration in AI-generated videos, the script must mimic natural speech patterns rather than formal written language. This means choosing vocabulary and sentence structures that reflect how people actually talk in casual or professional settings, depending on the context of the video.

One of the most common mistakes in scripting for AI narration is overloading sentences with complex phrasing or industry jargon. Instead, use concise, clear statements with a natural rhythm. This not only helps the AI sound more human but also keeps viewers engaged and improves message retention.

Key Practices for Writing Conversational Narration

• Use contractions: “it’s” instead of “it is”, “we’re” instead of “we are”.
• Write as if speaking to one person, not an audience.
• Insert pauses with commas or ellipses for a more natural flow.
• Break up long sentences into shorter ones to aid delivery.

Avoid robotic tone by imagining a real person reading the script aloud. If it feels awkward to say, it will sound awkward when narrated by AI.

1. Begin with a hook that addresses a common problem or question.
2. Follow with a logical flow: intro → context → solution → summary.
3. Use transitional phrases like “Now, let’s see…” or “Here’s the thing…”.

Problematic Phrase	Natural Alternative
It is necessary to utilize	We need to use
Commence the process	Let’s get started
Terminate the function	Stop it

Customizing Avatars and Voices to Match Your Brand

Creating a coherent digital identity starts with tailored visual and vocal elements. When producing AI-generated video content, aligning the avatar’s appearance and voice with your brand’s tone, target audience, and communication style ensures consistency across platforms. This includes selecting features such as facial characteristics, wardrobe, and speech intonation that reflect your brand values and audience expectations.

Fine-tuning these elements enhances viewer engagement and recognition. For example, a tech startup may choose a clean, modern avatar with a confident, fast-paced voice, while a wellness brand might opt for a calm, friendly figure with a warm tone. The more specific these choices, the more natural and professional the result will appear.

Key Customization Options

• Facial Features: Eye shape, skin tone, hair style, and age appearance.
• Wardrobe: Casual, professional, or industry-specific attire.
• Voice Characteristics: Accent, pitch, tempo, and emotional tone.
• Gesture Settings: Head movement, hand use, and facial expressions.

A consistent avatar and voice improve audience trust and brand retention by up to 70% compared to generic, off-brand content.

1. Define your brand persona: Is it energetic, authoritative, playful, or empathetic?
2. Select avatar presets that align visually with your messaging goals.
3. Adjust vocal settings to reflect your target demographic’s preferences.

Brand Type	Avatar Style	Voice Profile
Financial Services	Formal attire, mature features	Low-pitched, steady, confident
E-commerce Fashion	Trendy look, diverse styles	Friendly, upbeat, youthful
Healthcare	Clean, calming presence	Soothing, slow-paced, empathetic

Enhancing Videos with AI: Captions, Branding, and Graphic Elements

Integrating text overlays, branded visuals, and supplemental graphics into video content significantly improves viewer engagement and retention. AI-powered platforms such as Runway, Descript, and Pictory automate these enhancements with precision, allowing creators to focus on storytelling rather than technical editing.

Captions are generated automatically using speech-to-text engines, while visual assets like brand marks and illustrative elements can be positioned with frame-level accuracy. These tools also allow for quick revisions, enabling real-time updates to visuals and subtitles based on script changes or branding requirements.

Steps to Add Visual Enhancements with AI Tools

1. Import your video: Upload raw footage to an AI platform that supports timeline-based editing.
2. Generate subtitles: Use automatic transcription features to create time-synced captions with editable text layers.
3. Insert branding: Upload your logo and place it in consistent positions using anchor presets (e.g., top-right corner).
4. Add visual cues: Use AI-suggested elements like arrows, highlights, and icons to emphasize key moments.

• Auto-caption tools: Descript, Kapwing
• Logo placement with motion tracking: Runway, Adobe Firefly
• Stock visuals integration: Canva AI, Lumen5

For accessibility compliance and higher engagement, ensure captions have sufficient contrast and maintain brand consistency across all visual elements.

Optimizing AI-Generated Videos for Social Media Platforms

To achieve maximum engagement with AI-crafted videos, it’s critical to tailor output specifications to the unique requirements of each platform. TikTok favors vertical videos under 60 seconds, while YouTube Shorts also demands a 9:16 ratio but allows slightly longer formats. Aspect ratios, video length, and resolution directly influence how content is displayed in users’ feeds and can determine visibility.

Another crucial element is the first few seconds of the video. AI-generated intros must immediately capture attention using high-contrast visuals, quick cuts, or on-screen text that addresses the viewer’s intent or curiosity. Without a hook, even algorithmically favored content will fail to convert views into interactions.

Platform-Specific Adjustments

• Instagram Reels: Use 1080×1920 resolution; include auto-captions for silent viewing.
• YouTube Shorts: Keep within 15–60 seconds; prioritize strong thumbnails even for Shorts.
• Facebook: Square (1:1) or vertical (4:5) formats work best; avoid long intros.
• TikTok: Leverage native effects; ensure subtitles are hardcoded if auto-captioning is disabled.

“The success of AI-generated content isn’t in the automation–it’s in the precision of adaptation to viewer behavior.”

1. Export videos in multiple aspect ratios during generation.
2. Use platform-specific text overlays and CTA placements.
3. Test variations in hook timing and visual pacing for each platform.

Platform	Optimal Duration	Recommended Format
TikTok	9–15 seconds	9:16 Vertical
Instagram Reels	15–30 seconds	9:16 Vertical
YouTube Shorts	30–60 seconds	9:16 Vertical
Facebook Feed	15–60 seconds	4:5 Vertical or 1:1 Square

Editing and Refining AI-Generated Videos Without Starting From Scratch

When working with AI-generated videos, you may often find that certain aspects need refinement. Whether it’s adjusting a scene, changing the timing, or modifying voiceovers, knowing how to efficiently make changes without redoing everything can save you time and effort. By mastering the editing process, you can focus on fine-tuning individual elements while preserving the overall structure of the video.

Here are some practical methods for reworking your AI-generated video without starting from the beginning:

1. Adjust Scene Length and Transitions

One of the simplest ways to refine your AI video is by editing the timing of each scene or adjusting the transitions between them. This allows you to create a smoother flow and ensure the pacing fits your desired outcome.

• Cut or extend scenes to adjust timing.
• Modify the duration of transitions for a smoother visual experience.
• Use fade-in or fade-out effects to enhance scene transitions.

2. Change Visual Elements and Add New Content

If you feel certain visuals do not align with your message, you can replace specific clips or add new content without starting over. This can include background images, animations, or additional graphics.

1. Replace specific visuals using a new AI-generated image or video clip.
2. Incorporate stock footage or user-generated content where appropriate.
3. Adjust color grading and contrast to better fit the theme.

3. Modify Audio and Voiceover

AI-generated voiceovers or background music might not always be perfect on the first try. You can edit the audio tracks to refine the overall sound quality.

• Replace or adjust voiceover to better match the tone.
• Modify background music to ensure it complements the visuals.
• Fine-tune sound effects to make them more natural.

Tip: Always keep backup copies of your initial AI-generated video. This allows you to revert to the original if the edits don’t achieve the desired effect.

4. Optimizing the Final Output

Once you’ve made all necessary adjustments, it’s important to render the video with the highest possible quality while ensuring it meets your technical requirements. This is where exporting options come into play.
