Timeline frame rate mismatch → **6.25 seconds**\n2. Apply 50% speed (half speed) → **12.5 seconds**",
            "reasoning": "Here's a thinking process:\n\n1.  **Analyze User Input:**\n   - Original clip frame rate: 30 fps\n   - Timeline frame rate: 24 fps\n   - Original clip duration: 5 seconds\n   - Question 1: What is the new playback duration after placing it on a 24fps timeline?\n   - Question 2: If we apply 50% slow motion on top of that, what is the final duration?\n\n2.  **Understand the Core Concepts:**\n   - When a clip shot at one frame rate (30fps) is placed on a timeline with a different frame rate (24fps), the number of frames remains the same, but the duration changes because the timeline's frame rate dictates how many frames are displayed per second.\n   - Number of frames in original clip = 30 fps × 5 seconds = 150 frames.\n   - On a 24fps timeline, these 150 frames will play at 24 frames per second.\n   - New duration = Total frames / Timeline frame rate = 150 frames / 24 fps = 6.25 seconds.\n   - This is a standard \"speed change\" due to frame rate mismatch (often called \"frame rate conversion\" or \"time remapping\" in NLEs, but fundamentally it's just playing the same number of frames at a different rate).\n\n   - For Question 2: \"50% slow motion\" typically means the playback speed is reduced to 50% of its current speed. In video editing, 50% speed means the duration doubles.\n   - Current duration after step 1: 6.25 seconds.\n   - Apply 50% slow motion: Duration × (100% / 50%) = 6.25 × 2 = 12.5 seconds.\n   - Alternatively, 50% slow motion could be interpreted as \"slow motion by 50%\" which is ambiguous, but in standard video editing terminology, \"50% speed\" or \"50% slow motion\" means half speed, doubling duration. I'll clarify this assumption.\n\n   - Let's double-check: Sometimes \"50% slow motion\" might mean \"slow motion to 50% speed\" (i.e., half speed). Yes, that's standard.\n   - So final duration = 12.5 seconds.\n\n3.  **Calculate Step-by-Step:**\n   - Original frames: 30 fps × 5 s = 150 frames\n   - Timeline fps: 24 fps\n   - New duration: 150 / 24 = 6.25 seconds\n   - 50% slow motion (half speed): 6.25 s × 2 = 12.5 seconds\n\n4.  **Consider Potential Ambiguities/Edge Cases:**\n   - Does \"50% slow motion\" mean something else? In some contexts, people say \"50% slow motion\" to mean \"slow motion by 50%\", which is ambiguous. But in NLEs (Premiere, DaVinci, etc.), speed is usually expressed as a percentage of original speed. 50% speed = half speed = double duration. I'll state this clearly.\n   - Could it mean \"slow motion factor of 1.5x\"? Unlikely. Standard is 50% speed.\n   - Frame rate conversion methods: Some NLEs might drop or duplicate frames to maintain original duration, but the question implies standard behavior where frame count is preserved and duration changes (common in basic NLEs or when \"maintain frame rate\" is not forced). I'll assume standard behavior: frames are preserved, duration changes.\n   - I should explicitly state the assumption: \"Assuming the NLE preserves the original frame count (standard behavior when placing a 30fps clip on a 24fps timeline without frame rate conversion settings changed)...\"\n\n   - Let's verify with standard video editing knowledge:\n     - 30fps clip on 24fps timeline → plays slower → duration increases by factor of 30/24 = 1.25\n     - 5s × 1.25 = 6.25s. Correct.\n     - 50% speed → duration × 2 → 12.5s. Correct.\n\n5.  **Formulate Response:**\n   - Structure clearly: Answer (1), then Answer (2), with brief explanations.\n   - Show calculations.\n   - Clarify assumptions (frame count preservation, standard speed percentage interpretation).\n   - Keep it concise.\n\n   Draft:\n   (1) **New playback duration: 6.25 seconds**\n   - The original clip contains 30 fps × 5 s = 150 frames.\n   - When placed on a 24 fps timeline, those same 150 frames are played at 24 frames per second.\n   - Duration = 150 frames ÷ 24 fps = 6.25 seconds.\n   *(Note: This assumes your editing software preserves the original frame count, which is standard behavior when frame rates don't match.)*\n\n   (2) **Final duration after 50% slow motion: 12.5 seconds**\n   - In video editing, \"50% slow motion\" (or 50% speed) means the clip plays at half its current speed, which doubles the duration.\n   - 6.25 seconds × 2 = 12.5 seconds.\n\n   Check for accuracy: All math is correct. Terminology is standard. Assumptions are stated. Ready.✅\n   One minor point: Some might interpret \"50% slow motion\" as \"slow motion by 50%\" meaning 150% duration? No, that's non-standard. I'll stick with 50% speed = half speed = double duration, but I'll phrase it carefully: \"50% speed (half speed)\".\n   Actually, in Premiere Pro, \"Speed/Duration\" dialog uses percentage where 100% = normal, 50% = half speed.
