Create a realistic short video of a young male car mechanic standing in his workshop. He looks confident and friendly. The camera is in portrait mode (9:16). The mechanic is wearing a dark blue uniform with some oil stains, and behind him we see car tools, tires, and an open car hood. He speaks Arabic (Modern Standard Arabic) and says: "مرحباً! اليوم نحل مشكلة صوت من المحرك عند التشغيل." Add English subtitles that say: "Hi! Today we’re fixing an engine noise that appears when starting the car." Use natural lighting, realistic motion, and clear lip-sync to Arabic voice. Keep it short, around 10 seconds. Make it cinematic, realistic, and suitable for a YouTube Short or TikTok video.
