Be aware of upload limits. For instance, some platforms have a 413 Request Entity Too Large error if the file exceeds their specific size cap. 3. Troubleshooting "Improper" Files If your previous attempt was rejected or failed:
Use a reliable tool like Adobe Express Video Converter or Handbrake to re-encode the file using the "Fast 720p30" preset.
Maintain a constant frame rate (typically 23.976, 25, or 29.97 fps) to avoid "stuttering" issues. 2. Posting Requirements
AAC (Advanced Audio Coding) is the preferred audio format for MP4 containers to ensure it plays on all devices.
Use H.264 (AVC) for the video codec, as it is the industry standard for MP4 compatibility.
For 720p, a balanced file size is usually between 200MB to 500MB for a 20-minute episode to maintain quality without being unnecessarily large.
