GUIDE
Preparing video files
Formats, resolutions and vertical video: how to export episodes so they look right on phones, web and TV.
Guide6 min readUpdated Oct 2026

Pick the right orientation
Micro-drama is made to be watched on a phone held upright. NibbleFlix plays it in a vertical 9:16 player with swipe navigation between episodes. Films and series for OTT and smart TV apps are usually horizontal 16:9.
- Shoot vertical from the start. Cropping a horizontal frame to 9:16 loses picture and often cuts off faces.
- Respect the safe area. Keep faces and on-screen text away from the edges, where player controls sit.
- Go horizontal for TV-first content. Long-form titles for smart TVs work best in 16:9.
Recommended export specs
These are widely supported, safe settings. Start from a high-quality master, not a file already compressed for social media.
| SETTING | RECOMMENDED |
|---|---|
| Container | MP4 or MOV |
| Video codec | H.264 for the widest support, or HEVC (H.265) |
| Vertical resolution | 1080 x 1920 (9:16) |
| Horizontal resolution | 1920 x 1080 (16:9) |
| Frame rate | Keep the rate you shot at, and keep it constant |
| Audio | Stereo AAC |
| Subtitles | SRT or WebVTT (.vtt) as separate files |
Before you export
- Even out audio levels so viewers do not reach for the volume between episodes.
- Trim black frames and long silences at the start and end of each episode.
- Leave subtitles off the picture if you plan to offer more than one language.
- Name files consistently, for example series name, season and episode number.
Artwork and subtitles
- A poster for each series plus a thumbnail for each episode.
- Subtitle files timed to the final cut, not an earlier edit.
- Titles and synopses ready to paste in during upload.
Upload and check
Upload through the CMS in the admin dashboard. Test one episode end to end before you upload a whole season.
- Upload one episode and watch it on a phone, the web app and a TV.
- Check subtitles are in sync and readable on each screen.
- Batch upload the rest once the first episode looks right.
- Schedule releases so new episodes go live on a steady rhythm.
