Chaining Quick Recipe
Feed this clean frame as the starting keyframe of your next clip in Kling ("Extend Video"), Runway Gen-3 ("First Frame"), or Wan 2.1 Image-to-Video.
If the 0f frame has motion blur from rapid panning, click -1f or -2f in the micro-scrubber below.
Precision Frame Studio
Renders precision opening and ending frames with millisecond accuracy. Select the ideal keyframe to bypass motion blur, artifacts, or loop transitions.
Clip Loop Continuity (Selected Tail Frame vs Selected Head Frame)
Analyzes whether the clip's end frame seamlessly matches its opening frame for cyclic loops or reverse chaining.

Optimale framekeuze en negatieve prompts per AI-model.
Kling AI 1.5 & 2.0
Trending #1 for ExtensionsKling AI clips frequently suffer from a subtle 1-frame motion decay or luminance fade at the exact tail sample. Selecting -1f or -2f provides a significantly sharper subject edge for "Extend Video" chaining.
Runway Gen-3 Alpha & Turbo
Pro Filmmaking StandardIn Runway Gen-3, use the clean PNG as the "First Frame" of your next generation. Combine with Motion Brush to freeze stationary background elements.
MiniMax Hailuo AI (Video-01)
Photorealistic SOTAHailuo generates intense dynamic motion and human physics. The last 2 frames often feature velocity blur; using -2f guarantees a crisp focal plane.
Alibaba Wan 2.1 (14B)
Latest 2025 SOTA Open WeightsAlibaba Wan 2.1 is the latest breakthrough for image-to-video. When chaining in ComfyUI or WebUI, selecting -1f avoids end-sample latent slowing, providing flawless motion flow.
Luma Dream Machine (Ray 2)
Seamless Looping & Ray 2For perfect 360-degree loops or multi-shot sequences, extract both First Frame and Last Frame to verify seam difference before triggering "Extend".
Tencent HunyuanVideo (13B)
Cinematic Open WeightsHunyuanVideo uses a 3D VAE with excellent temporal stability. Feeding an uncompressed, C2PA-free PNG keyframe avoids latents artifacting during image-to-video initialization in ComfyUI.
Google Veo 2
4K Cinema FidelityVeo maintains exceptional adherence to prompt physics and 4K cinema resolution. Always use 100% uncompressed PNG to prevent compression macroblocking on the input keyframe.
PixVerse V3.5
Fast Multi-Shot KeyframingPixVerse V3.5 features dedicated Start & End keyframe fields. Use -1f to bypass final motion vector overshoot when chaining scenes together.
Pika Labs 2.1
Pikffects & Camera ControlUse Pika camera controls (Pan / Tilt / Zoom) locked to 0.1 strength when extending from the extracted keyframe to ensure smooth scene continuation.
OpenAI Sora
Closed Preview (Limited Access)Notice: OpenAI Sora remains in closed preview with waitlist access. For immediate, production-ready AI video chaining, use Kling AI 2.0, Runway Gen-3 Turbo, Hailuo, or Wan 2.1.
Midjourney Video
Artistic Style FocusPreserve Midjourney artistic style by feeding clean PNGs stripped of foreign EXIF so Midjourney can properly parse the starting frame aesthetics.

Technische Architectuur & GOP-Decodering
Het probleem met screenshots
Screenshots veranderen het kleurprofiel en voegen zwarte balken toe, wat een zichtbare sprong veroorzaakt.
Rechtstreekse MP4-decodering
We decoderen de exacte frames rechtstreeks uit de videopakketten zonder kwaliteitsverlies.
Hoe AI-video’s naadloos aan elkaar te koppelen
In 5 eenvoudige stappen.
Upload Clip A
Sleep de video naar de extractor.
Kies het scherpste frame
Gebruik 0f of -1f om eindonscherpte te omzeilen.
Kopieer de schone PNG
Ontvang een afbeelding zonder C2PA-markeringen.
Voeg toe aan Clip B
Gebruik als startframe in Kling of Runway.
Controleer en voeg samen
Inspecteer de overgang en exporteer als MP4.
Frequently Asked Questions
Worden mijn video’s geüpload?
Nee. Alles gebeurt 100% lokaal in uw webbrowser.
Waarom geen screenshot maken?
Screenshots veroorzaken een kleurafwijking van 2 tot 5% en verlagen de resolutie.
