-## Usage
-
-**Step 1:** Create the sample videos
-```bash
-./download-samples.sh
-```
-
-**Step 2:** Test the video processing tool with these samples
-
-Trim the 10-second video to first 5 seconds:
-```bash
-../trim-convert.sh -e 00:00:05 sample-10s.mp4
-```
-
-Extract middle portion of the 30-second video:
-```bash
-../trim-convert.sh -s 00:00:10 -e 00:00:20 sample-30s.mp4
-```
-
-Extract audio from the entire video:
-```bash
-../trim-convert.sh sample-10s.mp4
-```
-
-**Step 3:** Check the output files
-```bash
-ls -la trimmed.*
-```
