Format Conversion & Encoding

Format conversion and encoding for Hungarian productions runs through the transcode farms at Mafilm, Pannonia Post. Plus Origo Post, where AWS-style render-node clusters handle high-volume batch jobs in parallel and dedicated workstations handle the precision masters. We deliver mezzanine masters in ProRes 4444 XQ and DNxHR HQX at 4K DCI, UHD. Plus HD raster, alongside streaming encodes in H.264 / AVC, H.265 / HEVC, and AV1 tuned to each sites's bitrate ladder.

Here is how this works in practice. Multi-bitrate ABR ladders for HLS and DASH packaging, single-bitrate progressive MP4 for download, and per-title encode optimisation for the prestige tiers. Audio is transcoded to AAC LC, Dolby Digital 5.1, and Dolby Atmos joint-object-coding bitstreams as the target service needs, and frame-rate conversion between 24p, 25p. Plus 29.97 is handled with motion-compensated interpolation (Alchemist on Demand, Resolve's Optical Flow) so cadence and motion artefacts stay clean across NTSC, PAL, and cinema masters.

Here is the short of it. Subtitle and caption deliverables follow a parallel pipeline keyed to Hungarian and Central European bilingual norms. Hungarian-language IMSC1, SRT, and WebVTT for streaming and broadcast, bilingual EN/HU tracks for global co-pros and Netflix Hungary delivery, EN/DE tracks for the ORF Austria, RTL Deutschland. Plus cross-border DACH market that Hungarian production routinely services, and BCC and DCSubtitle for theatrical DCP. We author Apple TimeText ITT for iTunes and Apple TV+ deliveries, OP-47 teletext for MTVA / RTL Klub broadcast, and frame-accurate timing checks across every deliverable.

Here is the breakdown. HDR-to-SDR tone-mapping is watched by the same colourist who graded the HDR master so creative intent carries through to the Rec.709 versions. Plus every encode is verified through autoQC (Telestream Vidchecker, Interra Baton) plus eyes-on review before it ships. Plus checksums and delivery manifests issued alongside the assets so the receiving site can verify integrity on ingest.
