Step-by-Step Guide 👋


Open YouTube Studio  

– افتح كروم من أي مكان… غالبًا من سطح المكتب أو قائمة ابدأ، حسب ما تعودت.  

– go to https://studio.youtube.com and sign in.  


Select Your Video and Generate AI Subtitles  

1. Click “Content” → choose the video.  

2. Hit “Subtitles” in the left menu.  

3. Under “Add Language,” pick English → click “Auto-generate” (Gemini-powered).  

4. Wait a minute; the captions will appear—sometimes they lag, so be patient.  


Download the .srt File  

– Click the three dots next to the English track → “Download .srt.”  

– Save to C:\Users\Me\Documents\video-with-subs.srt.  

– I once forgot to switch my folder—ended up looking in “Downloads” for 10 minutes.  


Translate with a Free AI Tool  

• Go to https://www.kapwing.com/subtitle-translator (or Google Cloud Translation).  

• Upload your video-with-subs.srt.  

• Choose target language—Spanish, French, Japanese, whatever your audience needs.  

• Click “Translate” and wait a few seconds—translation quality isn’t perfect, but it’s a solid start.  


Review and Tweak  

– Download the translated video-with-subs-fr.srt.  

– Open in Notepad and fix misplaced line breaks or weird terms—AI sometimes writes literal translations.  

– Note: small manual edits boost accuracy more than you’d think.  


Re-Upload Translated Subtitles  

1. Back in YouTube Studio, go to “Subtitles” → “Add Language” → pick your new language.  

2. Click “Upload file” → select .srt → choose “With timing.”  

3. Hit “Publish.”  

4. Side note: if you have Google Drive sync on, sometimes YouTube auto-detects new files—still, manual upload is safer.

Manual vs AI Translation (No Table)


Manual translation vs AI tools: manual gives perfect nuance but eats days—AI gives speed, you just polish.  

Free tools vs paid APIs: free covers most languages; paid APIs handle bulk jobs and custom glossaries.  

Auto-translate in Studio vs external tool: Studio’s simple but limited; external tools offer more control and batch options.
