Common mistakes
- Uploading HDR (10-bit PQ/HLG) to X (Twitter). There is no published HDR path, so colours can look washed out; export SDR Rec. 709.
- Leaving phone footage at a variable frame rate. Export at a constant 30 fps, or audio drifts and motion stutters after X (Twitter) re-encodes it.
- Going over the length limit. X (Twitter): 140 seconds without a subscription; Premium up to 4 hours on x.com and iOS, 10 minutes on Android.
- Clipchamp always exports at 30 fps; 60 fps footage is converted to 30.
- Resolution is the only setting. For a size cap, compress the download with HandBrake.
For comparison, YouTube publishes 8 Mbps for 1080p at 30 fps. Example length used for sizes: 2:00.
