  • How do I turn a long video into YouTube Shorts with AI?

    Pick the moments in your long video that finish a complete thought, cut each one to a vertical 9:16 clip of up to three minutes (30 to 90 seconds suits most), burn in captions, and watch every clip before you upload it. An AI clipper can do the finding, cutting and captioning; you still approve each clip. Use a video you own.

  • Is there an OpusClip alternative with an API or MCP server?

    Yes. Klap has a REST API and an MCP server, and OpusClip has both too, so the real question is what your agent must be able to start. OpusClip and Klap let an agent submit a video by link. RemixViral has an MCP server and API, but its agent tools only read clip jobs a person uploaded and create faceless Shorts.

  • Which AI video clipper works with Claude over MCP?

    Three clip makers document a Claude route: OpusClip (a Claude.ai connector and a hosted MCP server for Claude Code), Klap (a Claude connector and an MCP server) and RemixViral (an MCP server with a Claude Code plugin). They differ in what Claude may start: OpusClip and Klap accept links, RemixViral reads clips from videos you uploaded.

  • Klap or OpusClip: which AI clip maker fits my videos?

    Both turn long videos into captioned vertical clips from a link or upload. Klap counts clips generated per month, lists sources up to 3 hours and 99+ languages, and publishes on every plan. OpusClip counts credits per minute of source video and gates its editor, reframing options, scheduler and MCP connector by plan. Run the same video through both before paying.

  • What is the best way to turn a podcast into Shorts automatically?

    Automate the mechanical work and keep the judgment. Let software transcribe the episode, rank candidate moments, cut them, reframe to 9:16 and burn in captions. You still choose which moments to publish and watch each clip once. Video podcasts work directly; an audio-only episode first needs a picture, such as a cover image or waveform.

  • What size, frame rate and bitrate should I export Shorts, Reels and TikToks at?

    Export vertical 9:16 at 1080x1920, H.264 video with AAC audio in an MP4, at the frame rate you recorded. Platforms' own pages differ on details: YouTube Shorts allows up to three minutes and 1080p, Instagram asks for at least 30 frames per second and 720 pixels, and TikTok's developer docs list 23 to 60 fps. Check each page before publishing.

  • How do I make a faceless Short from a topic with AI?

    Write a short script for one topic, record or generate a voice-over, add visuals that match each line, burn in captions, and cut it to vertical 9:16 at 30 to 60 seconds. AI tools can do each step from a topic prompt. Review the result, disclose realistic synthetic content, and vary every video so the channel is not mass-produced.

  • What is an AI video remixer, and how do I remix my own video without copying anyone?

    An AI video remixer re-cuts existing footage into new videos. Used on your own footage, that means new Shorts, trailers or recaps with new hooks, framing and captions. Used on someone else's video with a new voice, it is reused content, and copyright and platform rules still apply. Only remix footage you made or have rights to.

  • Is there a free AI clip maker for long videos?

    Partly. YouTube Studio can turn moments of your own uploaded videos into Shorts, ffmpeg is free software, and OpusClip and Klap each describe a way to try their tools on their own pages. RemixViral has no free plan that renews, but the first clip project is free within limits. Free routes usually make you choose and check the moments yourself, or limit what you can export.

  • Can I make Shorts from someone else's YouTube video or a link?

    Technically yes, but it depends on whose video it is and what you add. For your own videos, YouTube's Edit into a Short feature or a clipper works. For other people's videos, YouTube's reused-content policy applies even with the creator's permission, so you need real commentary or transformation. Copying a download with minimal changes is what the policy calls a violation.

  • How do I add captions to Shorts automatically?

    Generate a transcript with speech recognition, correct names and numbers by hand, then either let the platform show its own automatic captions or burn the text into the video so it always shows. YouTube generates automatic captions for Shorts but says to review them. A clip maker or ffmpeg can burn captions in. Keep text away from the bottom edge.

  • How do I turn a 16:9 video into 9:16 without cutting off the speaker?

    Cropping a 1920x1080 frame to 9:16 keeps only about 31.6 percent of its width, so choose the layout by where the speaker sits. Use a centred crop for a centred speaker, a shifted crop for an off-centre one, a blurred-background fit for slides or wide shots, and a stacked layout for two side-by-side speakers. Then watch every clip.

  • How do I turn a webinar or Zoom recording into short clips?

    Download the recording as a local video file, pick the self-contained moments (audience questions with their answers, a demo, a one-slide explanation), cut each to a vertical or square clip, keep slides readable with a fit or stacked layout instead of a tight crop, and burn in large captions. Get permission from people who appear, and review every clip.

  • How many Shorts can I get from one long video?

    As many as the video has standalone ideas, which is usually fewer than people hope. A rule of thumb is three to eight good Shorts from a typical one-hour episode. That is a judgment, not a benchmark. Count the self-contained moments in the transcript first; if you have to force a clip, it is probably the one to leave out.

  • How can I have an AI assistant pick the best clips from my long video?

    Give the assistant a timestamped transcript, plus your selection criteria and an output format, then check every timestamp it returns against the video. Alternatively, upload the video to a clip maker that ranks moments, and have the assistant read and re-rank those results over MCP. In both routes the assistant proposes, and you decide.

  • How do I let an AI agent use my video tool account without losing control?

    Give the agent its own credential with the fewest permissions that work, prefer read-only tools, cap what it can spend, keep a list of connected agents you can revoke in one click, and rely on your client's confirmation prompts for anything that costs money. Check each of those controls actually exists in the tool before you connect.

  • Why does my agent get INSUFFICIENT_CREDITS, VIDEO_LIMIT_REACHED or 429 from the RemixViral MCP server?

    INSUFFICIENT_CREDITS (402) means the balance is below the cost of create_video. VIDEO_LIMIT_REACHED (403) means the account has no plan or credits, so a human must act. 429 means either the key's hourly request limit or three videos already rendering. Do not retry the first two; wait for the reset on 429.
