PFM in sintesi
PFM
Convert to PFM when high-precision floating-point image data must survive for rendering, HDR processing, or technical analysis.
It is useful as a working format in graphics and research pipelines.
3GP in sintesi
3GP
Convert to 3GP when preserving or processing older mobile phone footage, MMS-era videos, or device-targeted clips for constrained mobile environments.
It is a reasonable compatibility target for archival workflows involving legacy handsets.
For general-purpose delivery, MP4 is the more practical modern choice.
