Creating Longer Videos

Limitation

Grok Imagine generates 6-10 second clips. For longer videos, use stitching techniques.

Method: Video Stitching with FFmpeg

Step 1: Generate Multiple Clips

1. Create sequence of related prompts
2. Generate each clip separately
3. Download all clips to device
4. Transfer to computer for stitching

Example Sequence:

Clip 1: "Opening shot: Aerial view of a beach at sunrise"
Clip 2: "Medium shot: Waves rolling onto the shore"
Clip 3: "Close-up: Seashell on the sand with foam approaching"
Clip 4: "Wide shot: Seagulls flying over the ocean"
Clip 5: "Final shot: Sun fully risen, beach panorama"

Step 2: Stitch with FFmpeg

# Create file list
cat > filelist.txt << EOF
file 'grok-clip-1.mp4'
file 'grok-clip-2.mp4'
file 'grok-clip-3.mp4'
file 'grok-clip-4.mp4'
file 'grok-clip-5.mp4'
EOF

# Concatenate videos
ffmpeg -f concat -safe 0 -i filelist.txt -c copy beach-sequence.mp4

# Result: ~30-50 second video (5 clips × 6-10s each)

Step 3: Add Transitions (Optional)

# Add crossfade transitions between clips
ffmpeg -i grok-clip-1.mp4 -i grok-clip-2.mp4 \
  -filter_complex "[0:v][1:v]xfade=transition=fade:duration=0.5:offset=5.5[v]" \
  -map "[v]" output.mp4

Integration with Other Skills

Send via Telegram

// Generate video with Grok → Download → Send
async function grokToTelegram(prompt, chatId) {
  // 1. Generate video in Grok app (manual)
  // 2. Download to device
  // 3. Transfer to computer
  // 4. Send via Telegram skill
  
  const videoPath = '/path/to/downloaded/grok-video.mp4';
  // await sendTelegramVideo(chatId, videoPath);
}

Social Media Workflow

1. Generate video with Grok Imagine
2. Download to device
3. Edit/enhance if needed
4. Post to X directly (native integration)
5. Cross-post to other platforms
