Lùkā AI

What is LuKa AI?

RecCloud, whose English name is RecCloud AI, is a one-stop AI audio and video processing platform. It combines functions such as text-to-speech, automatic subtitle generation, subtitle translation, speech-to-text, video translation, audio and video summarization, text-to-video creation, video segmentation, subtitle removal, screen recording, online editing, and cloud file management under a single account. It is designed for use in meeting transcription, course creation, short videos, podcasts, and the production of cross-border content.

The advantage of RecordKa is its centralized workflow: users can upload audio and video files, after which the text and speaker are identified; followed by translation, proofreading, and generation of voiceovers or subtitles, before the final combined file is ready for download. Different functions have their own restrictions regarding file format, size, duration, and computational resources, and the free trial offered on one platform does not mean unlimited free access across all platforms.

AI voice-to-text

Text-to-speech conversion can process recordings, interviews, meetings, lectures, and video dialogues to generate editable text; it also offers additional functions such as editing, summarization, translation, and asking questions based on the content. It is ideal for quickly turning long videos and audios into meeting minutes, draft subtitles, article material, or study notes.

The accuracy of recognition is affected by the quality of the audio, accent, background noise, multiple speakers speaking at once, specialized terminology, and music. In medical, legal, financial, contractual, and official documentation, it is necessary to compare the text with the original audio manually; the highest accuracy rates shown on promotional materials should not be used as a guarantee for all documents.

Distinguishing between the speaker and meeting summarization

When uploading audio, it is possible to specify the different speakers; the system will identify each voice and divide the content into segments labeled with the corresponding speaker, thereby reducing the workload associated with manually organizing interview and meeting transcripts. Once the text is generated, it can be copied, translated, or summarized.

Long-distance audio reception, multiple people speaking at the same time, and similar voice tones can lead to confusion regarding the identities of the participants. In important meetings, it is necessary to correct names, company names, numbers, times, and action items before distributing the minutes.

AI subtitle generation

Lùkā is capable of automatically identifying dialogue from audio and video content to generate subtitles; it allows for online editing of text, timelines, and styles, and it enables the creation of subtitles in single or dual languages. The official website states that it supports 99 different languages, making it suitable for short videos, courses, interviews, film clips, and social media content.

Automatic sentence segmentation and the timeline may still not appear natural. For formal works, it is necessary to check the number of characters per screen, the reading speed, line breaks, punctuation, terminology, as well as the safe area for the visuals; moreover, it is important to determine whether a subtitle file or a video with embedded subtitles is being exported.

Subtitle translation and multilingual videos

Subtitle translation allows the results of text recognition to be converted into the target language, with further adjustments possible regarding font style, color, position, and display format. For cross-border content, users can first create subtitles in the original language, correct them sentence by sentence, and then translate them; this approach makes it easier to control the final outcome compared to attempting to generate subtitles directly from low-quality audio.

Slang, puns, character relationships, and the tone of a brand all require review by a native speaker. Accurate subtitles do not necessarily mean a natural-sounding voiceover; for multilingual versions, it is also necessary to check the length of the text, lip movements, rhythm, and the platform’s approval rules.

AI video translation and dubbing

Video translation allows for the simultaneous processing of dialogue transcription, text translation, voice-over in the target language, and subtitle generation; it is suitable for using in courses intended for international audiences, product presentations, YouTube content, and corporate training. Users can preview and modify the translations, subtitles, and audio online before exporting the final video.

The number of supported languages may be indicated as over 70, 99, or more than 100 on different pages; this figure usually depends on the specific sub-functions and the input/output combinations. Before making a purchase, it is necessary to confirm the source language, target language, voice settings, and file limitations for the desired functions.

Translation for short-form dramas going global

The short drama translation module is designed for the localization of large numbers of episodes; it offers options such as subtitle translation, dubbing combined with subtitles, and voice cloning. It can identify the characters and assign them appropriate voices. The official website states that 100 episodes, each lasting 2 minutes, can be processed in about 4 hours, but the actual time required depends on the queue, the quality of the material, and any manual proofreading needed.

Short-form dramas require consideration of linguistic context, emotions, character consistency, and cultural appropriateness; the AI-generated drafts still need to undergo translation review, voice-over quality checks, and copyright verification. The figures regarding speed improvements and cost reductions cited in promotions are estimates based on official scenarios, and they are not guarantees for every project.

Text to speech

Text-to-speech conversion allows scripts to be rendered with voiceovers in multiple languages such as Chinese, English, and Japanese, offering a variety of male and female voices as well as different vocal styles. It is suitable for use in narrations, courses, audio articles, ad previews, and accessible reading; once generated, the audio can be integrated with subtitles and video sequences.

Names, numbers, abbreviations, and technical terms are prone to being mispronounced; long scripts should be listened to in segments so that the pronunciation remains consistent. For commercial projects, it is necessary to verify whether permission exists for using a particular voice tone, and it is not allowed to use real people’s voices without consent.

Voice cloning

Some text-to-speech and video translation services allow for the customization of voice tones; it is possible to create a specific sound style using a small amount of recorded audio, which can then be used for multilingual rendering or bulk voiceovers. This approach is suitable for creating brand voices or localizing characters, provided that authorization has been obtained from the respective individuals or actors.

Voice is a sensitive biometric feature; clear and verifiable authorization must be obtained, along with specifications regarding its intended use, language, duration, deletion procedures, and commercial applications. It must not be used for fraud, impersonation, false endorsements, or to circumvent the platform’s disclosure requirements.

Audio and video summary and AI dialogue

Audio and video summaries can extract themes, key points, and subtitles, and allow further questions to be posed based on the content of the file, thereby helping users to quickly understand long courses, meetings, interviews, or online videos. They are suitable for initial screening and for creating reading guides.

Summaries may overlook certain constraints, opposing viewpoints, or details; AI-driven responses might also include information that is not present in the original video. When quoting exact words, specific times, or key conclusions, it is necessary to refer back to the subtitles and the original media for verification.

AI video generation

Lùkā offers a way to generate videos from text, and it includes a feature called “AI Help Me Write” to assist in creating scripts. The product page also displays various video models and generators, which are suitable for producing concept videos, content for social media, and creative samples.

The model, resolution, duration, generation speed, and computational resources used will keep changing. The resulting videos may exhibit inconsistencies in the appearance of the characters, text errors, and distorted movements; before using them for commercial purposes, it is necessary to check the rights related to the prompt words, reference images, music, and the output material.

Video segmentation and secondary distribution

AI video slicing allows for the extraction of key segments from longer videos, which can then be used on short-video platforms, as previews for courses, or in podcasts. While automated selection saves time during the initial editing process, human oversight is still needed to ensure that the narrative is complete and that the context and titles are accurate.

Quoting excerpts from interviews or speeches out of context can alter their original meaning. It is necessary to retain the relevant context before publishing, and to ensure that there are proper licenses for the use of images, music, videos, as well as any derivative works created on various platforms.

Removing subtitles and text from videos

The subtitle removal function is designed for removing fixed subtitles or text overlays that are already present on the video screen; AI detects those elements and reconstructs the background. The tool supports processing either individual files or batches of them, with common file formats including MP4, MOV, WebM, and MKV – the output format is usually MP4.

Complex textures, moving cameras, transparent text, and occluded characters can result in blurring or repair artifacts. Soft subtitles or separate SRT files can usually be simply turned off or deleted, without the need for AI reconstruction.

Removing watermarks, station IDs, and copyright notices does not grant the right to use the material.

Screen recording, online editing, and cloud storage

In addition to its AI features, RecordKa also offers browser screen recording, video trimming, cropping, merging, speed adjustment, conversion to GIF format, audio extraction, file sharing, and cloud storage. Users can carry out recording, processing, and distribution tasks within the same workspace.

Cloud processing requires uploading the original files; long videos consume network bandwidth, storage space, and download quotas. For sensitive meetings and customer materials, it is necessary to first read the privacy policies and deletion rules, and to keep the original files locally.

Supported platforms

Lùkā can be used in a web browser, and there are also options available for iPhone, iPad, and Windows apps. After purchasing a membership, the official instructions state that the same VIP account can be used to log in on mobile devices, tablets, and computers, thereby unlocking the corresponding benefits.

Cross-device compatibility does not mean that all functions are identical across all devices. The specific AI models, methods of data import, screen recording capabilities, batch processing options, and export formats may vary depending on the system and version; it is advisable to test important workflows on the target device first.

Members and particle counting

Lùkā adopts a billing system based on members and \"calculation units\". Purchasing an annual or short-term membership grants a certain number of calculation units, which can also be bought separately after becoming a member.

Different AI functions incur charges based on minutes, characters, seconds, file size, or the scope of the task; the official source specifies that these rules may change in accordance with fluctuations in costs.

The dynamic table on the current public pricing page does not always display the complete self-service pricing accurately; as a result, the catalog may reference invalid promotional figures. The real-time prices, free items included, cloud storage space, and feature benefits for regular, premium, and business members should be based on those shown on the settlement page after logging in.

Calculate the validity period

The counting units included in the membership package are only valid during the membership period and become invalid once it expires; the counting units purchased separately are valid for one year from the date of purchase, and any unused units will be reset after that period.

Before starting batch translation or generation, it is necessary to estimate the length of the task and check the balance and expiration date.

The official page confirms that text transcription and audio/video summarization are typically charged on a per-minute basis, while downloading and sharing can also consume usage credits; the values displayed for subtitles, translation, video generation, and subtitle removal may be subject to changes or adjustments, so it is necessary to verify them again before settling the bill.

Individual and commercial usage rights

The official purchase instructions clearly distinguish between regular, premium, and business members. The main difference between regular and premium members lies in the number of free particles provided, and both types are intended for personal use only, for non-commercial or non-profit purposes.

In addition to various additional benefits, business members are allowed to use the generated audio and video files in commercial and profit-driven contexts.

Business members do not automatically resolve the copyright issues related to the materials uploaded by users. For content such as films, music, portraits, brands, scripts, and cloned voices, it is still necessary to obtain the necessary permissions; before making a purchase, one should keep track of the applicable rights and terms.

Refunds and automatic renewal

The official price page states that a refund is available within 7 days in case of dissatisfaction; for weekly members, the deadline is 3 days. The specific terms are as outlined in the refund policy. Users who have enabled automatic renewal via WeChat or Alipay need to turn off this automatic deduction feature in the settings of those payment applications.

The refund processes for orders placed through different app stores, partner shopping sites, and the official website may vary. After trying out a product, it is necessary to check its quality, the ability to export data, as well as the licensing terms within the allotted time, rather than waiting until a large amount of resources have been used before making a decision.

Lùkā API

Lùkā offers AI-based APIs for audio and video processing, covering functions such as converting audio and video to text, text to speech, generating videos from text, subtitle recognition, and multilingual translation. The API Key available for free has a QPS limit of 2, making it suitable for development and testing purposes.

The API documentation states that an HTTP status of 200 indicates that the request was successful, but it does not mean that the conversion task has been completed. The result link is generally valid for only 1 hour, so the application must periodically check the status of the task and download the results to its own storage system.

In a production environment, it is also necessary to handle retries, idempotency, timeouts, callback verification, and cost limitations.

Is it open source?

The RecordKa website, its mobile versions, AI models, and cloud services are not open-source projects; the company does not provide the complete core code that can be used for private deployment. These services fall under the category of online SaaS and API services, and their use requires an account, an internet connection, as well as appropriate usage quotas.

Even if some clients rely on open-source components, it does not mean that the core functionalities of Lùkā are licensed under an open-source license. Companies with requirements regarding internal network deployment, data retention, and dedicated SLAs should contact the sales team for clarification.

Data security

The official price page lists certifications such as ISO/IEC 27001 and ISO/IEC 27701, as well as information regarding GDPR compliance; it also states that encryption and access controls are used to protect the files. For ordinary creators, this makes it easier to assess whether a particular tool is suitable for purchase compared to temporary tools that provide no such information.

Authentication does not mean that there is no risk associated with any data uploads. Companies should also verify the location where the data is stored, the retention period, the sub-processors involved, the purposes for which the models are trained, the proof of data deletion, employee access rights, procedures for reporting incidents, and the contractual responsibilities.
