Step-by-Step: Video Painter → FLV for Web Playback
Overview
This guide shows a straightforward workflow to export or convert Video Painter projects into FLV files optimized for web playback, assuming Video Painter can export to a common intermediate format (like AVI, MOV, or MP4). If Video Painter exports directly to FLV, skip the conversion step and use the export settings section.
1) Export from Video Painter
- Format: Export to a high-quality intermediate (preferably MP4 H.264 or MOV with lossless/ProRes if available).
- Resolution: Match your target web resolution (720p or 480p for faster loading; 1080p if you need higher quality).
- Frame rate: Keep the original frame rate (commonly 24/30/60 fps).
- Audio: Export as AAC or uncompressed WAV if available.
- File name: Use a concise name with no spaces (e.g., projectnameexport.mp4).
2) Convert to FLV
- Use a conversion tool (FFmpeg recommended) when Video Painter cannot export FLV directly.
- Example FFmpeg command (replace filenames as needed):
Code
ffmpeg -i projectname_export.mp4 -c:v flv -ar 44100 -c:a libmp3lame -ab 128k -r 30 -s 640x360 output.flv
- Notes on flags:
-c:v flvselects the FLV video codec.-c:a libmp3lame -ab 128kencodes audio as MP3 at 128 kbps.-rsets frame rate;-ssets resolution for smaller files.- Adjust bitrate and resolution to balance quality and file size.
3) Optimize for web playback
- Resolution: 640×360 or 854×480 for general web use; 480×270 for mobile-first.
- Bitrate: 500–1200 kbps video for 480p; 1200–2500 kbps for 720p.
- Audio: 96–128 kbps MP3 or AAC.
- Keyframe interval: Set GOP/keyframe every 2–3 seconds (use
-gin FFmpeg, e.g.,-g 60for 30 fps). - File size: Aim for under 10 MB for short clips when possible.
4) Test playback
- Test in an FLV-compatible player (e.g., older Flash players or VLC).
- Verify sync, seek behavior, and quality across browsers/devices you target.
5) Delivery options
- Host as a direct downloadable FLV for legacy players.
- Prefer modern alternatives: convert to MP4 (H.264/AAC) for wide browser support and use adaptive streaming (HLS/DASH) if possible.
- If you must use FLV, consider providing an MP4 fallback.
Quick checklist
- Export high-quality intermediate from Video Painter.
- Use FFmpeg to convert if needed (sample command above).
- Optimize resolution, bitrate, audio, and keyframes.
- Test playback and provide modern fallbacks.
If you want, I can generate an FFmpeg command tailored to your source file properties (resolution, frame rate, duration).
