Turn stock analysis videos into searchable notes
A private investor used SozAI to turn roughly 20-minute Chinese equity analysis videos into skimmable transcripts, then find EPS figures, growth rates, and other details without re-watching.
In short
For a private investor reviewing Chinese equity-analysis videos, SozAI converts each recording into a searchable transcript with speaker labels and word-level timestamps. The investor scans terms such as EPS, revenue, margins, growth, and guidance, then exports relevant passages as TXT or DOCX. This workflow replaces repeated timeline scrubbing with searchable text while preserving the surrounding spoken context.
The setup
- Who
- Private investor
- Typical recording
- Chinese equity-analysis video, about 20 minutes
- Volume
- Repeated individual video uploads
- Languages
- Chinese; 100+ supported
- Devices
- Website, macOS, iOS, Android
- Export used
- TXT for searchable notes; DOCX for review
- Storage
- EU data centers; AES-256 encryption at rest
The numbers come from anonymized aggregates from SozAI production usage and the public transcript library, not one named organisation.
One figure should not require a full replay
Useful investment research often sits inside long-form video. Earnings breakdowns, stock theses, and market commentary may contain an important figure or management comment, but that information remains buried in spoken analysis.
In this scenario, the investor regularly reviewed Chinese equity analysis videos of about 20 minutes. Confirming one EPS figure, growth rate, or earnings-related comment meant scrubbing through the timeline, replaying sections, and typing notes by hand.
That process interrupted research and made it harder to compare several videos. This case is a composite built from anonymized usage patterns in production. The recurring need was to turn spoken market analysis into text that could be skimmed, searched, and revisited.
What the research required
A transcript built for targeted review
The investor uploaded each video to SozAI and received a transcript that could be read like research notes. Instead of listening through the entire recording, the investor could scan for revenue, EPS, margins, year-over-year growth, and the reasoning behind each point.
Transcript search became the quickest route to a specific term or number. When more context was needed, the investor could use the surrounding transcript to locate the relevant moment in the original recording.
SozAI’s production usage spans 20+ languages, which also suited research involving non-English market content. Spoken analysis became a reusable text record rather than information tied only to a video timeline.
How the workflow looked
- 1 Upload a stock or earnings analysis video, including Chinese-language market commentary.
- 2 Let SozAI generate a transcript with speaker labels.
- 3 Scan the transcript for EPS, growth rates, guidance, valuation points, and related commentary.
- 4 Search for a specific figure instead of scrubbing through the video.
From replaying to reviewing
A spoken market breakdown became text the investor could skim, search, and revisit while comparing investment ideas.
Video became research notes
A roughly 20-minute market breakdown became a transcript that could be reviewed without replaying the full video.
Financial details were easier to review
EPS, growth rates, and other figures were visible in the transcript alongside the surrounding analysis.
Search replaced timeline scrubbing
When the investor needed one figure, transcript search led directly to the relevant passage.
Why this workflow fit finance research
Text supports repeated review
Scanning a transcript made it easier to revisit a point than listening to the same passage again.
Context stayed with the figures
EPS, growth, guidance, and valuation points appeared alongside the commentary explaining them.
Search answered specific questions
The investor could look for one term or figure without reviewing every minute of the video.
How long each step takes
- Upload the recordingUpload time varies by file size
The investor uploads a stock or earnings-analysis video to SozAI through the website or a supported device. Files can be up to 500 MB and about 2.8 hours per file.
- Generate the transcriptAbout one tenth of the recording length
SozAI transcribes audio and video at about 10x real time. A 50-minute recording is typically ready in about five minutes, with speaker labels included in 99% of transcripts produced in the app.
- Search the research textDuring the review session
The investor searches for EPS, revenue, margins, year-over-year growth, guidance, valuation, and related commentary instead of repeatedly scrubbing through the video. Word-level timestamps connect text to the original recording.
- Export the notesAfter the transcript review
The investor exports the transcript as TXT or DOCX for continued research. PDF, SRT, and VTT are also available when those formats are required.
What this workflow does not do
Accuracy depends on the recording
SozAI reaches around 99% word accuracy on clear speech recorded with a decent microphone. Accuracy falls with overlapping speakers, heavy accents, background noise, and phone-quality audio.
A transcript is not financial verification
SozAI transcribes spoken claims but does not fact-check EPS figures, growth rates, valuation assumptions, or management statements. Financial details still require comparison with source documents.
Search does not replace context
SozAI can locate a matching term in the transcript, but the investor must review surrounding sentences and the original recording when tone, qualification, or pronunciation affects interpretation.
File and language constraints apply
SozAI does not accept files above 500 MB or about 2.8 hours per file. It supports 100+ languages with automatic language detection, but recognition quality still depends on audio clarity and language coverage.
Terms used on this page
- Speaker labels
- Speaker labels identify different voices in a transcript through diarization.
- Word-level timestamps
- Word-level timestamps attach timing information to individual words so a reader can locate the corresponding moment in the recording.
- Diarization
- Diarization is the process of separating a recording into labeled speakers.
- SRT and VTT
- SRT and VTT are subtitle file formats that preserve transcript text with timing information.
A wider use for spoken research
This finance scenario reflects a broader pattern across SozAI’s 5,400+ users. In production, the app has processed 9,600+ jobs and transcribed 1,360+ hours of audio and video into text people can review and reuse.
Multilingual research is part of that usage: content has been processed in 20+ languages, with translations available into 15+ target languages. This case study is a composite of anonymized usage patterns, not the account of one named individual.
Answers
Questions about this workflow
How does a private investor turn Chinese stock videos into searchable notes?
SozAI accepts the stock or earnings-analysis video and produces a transcript with speaker labels and word-level timestamps. The investor searches the transcript for EPS, revenue, margins, growth, guidance, or valuation terms, reads the surrounding commentary, and exports the result as TXT or DOCX. This creates a text record that can be reviewed without replaying the entire video.
How accurate is SozAI for financial analysis videos?
SozAI provides around 99% word accuracy on clear speech recorded with a decent microphone. Accuracy falls when speakers overlap or when the recording contains heavy accents, background noise, or phone-quality audio. SozAI transcribes the spoken content but does not verify whether an EPS figure, growth rate, or other financial claim is correct.
Can SozAI find a specific EPS figure in a video?
SozAI turns the video into searchable transcript text, allowing an investor to search for EPS, revenue, margins, growth, guidance, or related terms. Word-level timestamps show where the matching words occur in the recording. The investor should read the surrounding passage and replay the source when the number or qualification needs confirmation.
What file formats can SozAI export for research notes?
SozAI exports transcripts as TXT, DOCX, PDF, SRT, and VTT. TXT and DOCX fit text-based research notes, while SRT and VTT preserve subtitle timing. SozAI includes word-level timestamps, which help connect a financial statement in the transcript to its position in the source recording.
Does SozAI support Chinese recordings and automatic language detection?
SozAI supports Chinese recordings and more than 100 languages, with automatic language detection. Real usage includes more than 20 languages. Recognition quality depends on the recording, so clear speech and a decent microphone remain important when the transcript contains financial names, figures, abbreviations, or technical terminology.
How large can an investor's video file be in SozAI?
SozAI accepts files up to 500 MB and about 2.8 hours per file. Transcription runs at about 10x real time, so a 50-minute recording is typically ready in about five minutes. Files are processed and stored in EU data centers, with AES-256 encryption at rest.
