The total cost depends on how long the model runs. It costs $0.000247 per second. Based on an average runtime of 20 seconds, each run costs about $0.004950. With a $1 budget, you can run the model around 202 times.

API & SDK

Create a Prediction

Send a POST request to create a new prediction. This will return a prediction ID that you'll use to check the result. The request should include your model inputs and API key.

Get Prediction Result

Poll the prediction endpoint with the prediction ID until the result is ready. The API uses long-polling, so you'll need to repeatedly check until you receive a success status.

Overview

merge-videos — Video-to-Video AI Model

merge-videos from Eachlabs revolutionizes video-to-video workflows by leveraging FFmpeg-powered merging to combine multiple clips into seamless, high-quality outputs without quality loss or complex editing software. Perfect for creators and developers seeking an efficient video-to-video AI model, it handles cinematic edits and storytelling by stitching clips with precise transitions, eliminating manual timeline hassles. Developed by Eachlabs as part of the eachlabs family, merge-videos stands out for its reliability in producing smooth, professional-grade videos from disparate sources, supporting eachlabs video-to-video needs like social media compilations or promotional reels.

Technical Specifications

What Sets merge-videos Apart

Unlike generative video-to-video AI models that create new content from prompts or images, merge-videos focuses on deterministic merging of existing clips using FFmpeg, ensuring pixel-perfect concatenation without artifacts or re-encoding degradation. This enables users to build long-form videos from short clips reliably, ideal for workflows requiring exact control over timing and sequence.

Key technical specifications include support for common input formats like MP4, AVI, MOV, and MKV, with outputs in high-quality MP4 or WebM up to 4K resolution if source clips match. Processing times average under 10 seconds for clips totaling 5 minutes, far faster than manual editors, making it a top choice for merge-videos API integrations in automated pipelines.

  • Lossless merging via FFmpeg: Concatenates clips with frame-accurate alignment and optional crossfades, preventing quality drops common in online editors; this allows creators to scale storytelling projects effortlessly.
  • Batch multi-clip support: Handles 2-20+ clips in one run with customizable order and transitions; developers benefit from scripting complex sequences for apps like AI video merger tools.
  • Flexible output controls: Adjusts bitrate, resolution scaling, and audio mixing on-the-fly; users achieve cinematic results tailored for platforms like YouTube or TikTok without post-processing.

Key Considerations

  • Ensure all input clips use compatible codecs and frame rates to avoid synchronization issues
  • For best results, preprocess clips to match resolution and aspect ratio before merging
  • Use lossless or high-bitrate settings for professional-quality outputs; lower bitrates may speed up processing but reduce quality
  • Carefully manage audio tracks to prevent desynchronization, especially when merging clips with different audio formats
  • Advanced users can customize FFmpeg command parameters for fine-grained control
  • Avoid merging clips with drastically different color profiles or dynamic ranges without prior normalization
  • Batch processing is possible but may require scripting for automation

Tips & Tricks

How to Use merge-videos on Eachlabs

Access merge-videos through Eachlabs Playground by uploading multiple video clips (MP4, MOV, up to 50MB each), specifying order, transitions like fade or cut, and output settings such as resolution or bitrate. For production, integrate the merge-videos API or SDK to automate via URLs or file paths, polling for high-quality MP4 outputs—ideal for scalable video workflows.

What Can I Use It For?

Use Cases for merge-videos

Content creators building cinematic edits can upload raw footage clips saying "merge these three drone shots with soft crossfades and unified audio levels," producing a polished travel vlog ready for upload in seconds—leveraging its FFmpeg precision for seamless video merging AI results.

Marketers crafting promotional reels feed product demo clips plus B-roll, using merge-videos to sequence them into cohesive ads; its batch handling ensures brand-consistent outputs for e-commerce campaigns without desktop software.

Developers integrating merge-videos API into apps automate user-generated content pipelines, like combining short user videos into compilations; the fast processing supports real-time features in social platforms or event apps.

Filmmakers in pre-production stitch storyboards or test footage, applying transitions via simple parameters; this accelerates prototyping for eachlabs video-to-video workflows, maintaining original quality across aspect ratios.

Things to Be Aware Of

  • Some users report a steep learning curve when customizing advanced FFmpeg parameters
  • Audio synchronization issues can arise if input clips have mismatched codecs or sample rates
  • Performance is highly dependent on hardware; older systems may experience slower processing
  • Resource requirements are modest for basic merges but increase with higher resolutions and complex filters
  • Consistency of output is praised in recent reviews, especially when input clips are well-prepared
  • Positive feedback centers on the tool's flexibility, speed, and quality of results
  • Negative feedback often relates to the need for manual intervention in complex workflows and limited GUI options for advanced settings

Limitations

  • Relies on FFmpeg's capabilities; may not support proprietary or unusual formats without additional codecs
  • Not optimal for merging clips with drastically different technical characteristics (resolution, frame rate, color space) without preprocessing
  • Advanced features may require scripting or command-line expertise, limiting accessibility for some users
FREQUENTLY ASKED QUESTIONS

Dev questions, real answers.

Merge Videos is a video utility model developed by each::labs that concatenates multiple video files into a single, continuous output video. It handles format normalization and seamless joining of video segments, enabling automated video assembly from individually generated or recorded clips.

Merge Videos is accessible via the eachlabs unified API. Submit multiple video files in the desired sequence order; the model returns a merged, single video file. As a native each::labs utility, it is directly integrated with no additional configuration required billing is pay-as-you-go.

Merge Videos is best suited for automated video production pipelines, content management systems, and media workflows that generate individual video segments programmatically. It is particularly useful for assembling AI-generated video clips, episode chapters, or multi-scene outputs into a final deliverable.
