Post-Production Formats And Suitable Workflows
Kieron Seth considers the support for acquisition formats and the key issues surrounding suitable workflows for editing in post...
There’s a trade-off between native support for camera codecs and codecs that are appropriate for use in post-production workflows – a clear dichotomy has emerged. Consider Adobe’s pitch: “Work with the latest tapeless formats thanks to new native support in Adobe Premiere Pro software for ARRI Alexa, RED Scarlet-X and RED EPIC, and Canon Cinema EOS C300 cameras, as well as XDCAM HD 50, AVCCAM, DPX, and AVC-Intra and DSLR footage. Native support means you won’t waste valuable production time transcoding or rewrapping and always have access to the original file’s pristine quality.” A stance supported by Grass Valley’s claims: “EDIUS continues 58 to be the world’s fastest editor when mixing formats such as MPEG2, H.264, and DVCPRO all on the same timeline... EDIUS software also provides support for virtually all industry-standard equipment and formats, including the new Canon XF format and Canon EOS movie format. Supported input formats include P2, XDCAM, GF, AVCCAM, NXCAM, QuickTime, and Windows Media. It also supports all DV and HDV cameras and decks and 3D post production.” Formats, it seems are an irrelevance in post-production. Place any clip on the timeline, edit natively and complete the project, quickly and without a fuss. Then again, neither Adobe nor EDIUS

Avid states: “Native HD c a m e r a compression for mats a re Atomos field recorders offer multiple format options efficient, but simply aren’t engineered to dismiss as unnecessary and timeconsuming. Avid may have a point… maintain quality during complex post-production effects processing.

In an Next up is Apple: “Many of today’s industry dedicated to image quality, HD formats were developed under picture deterioration is simply significant camcorder engineering unacceptable. Many HD formats, constraints and therefore limit the full such as AVC-Intra 50, HDCAM and quality that can be carried in an HD DVCPRO HD can visibly suffer multisignal.
