I came here to request this feature as well. Coming to Bitwig recently from a filmmaking background, video support was the first (and biggest) missing piece I noticed. I do recognize Bitwig as a musician-focused DAW and turning it into a full-fledged film post-production DAW is probably a bad idea. The complexities involved along with the specific requirements for filmmaking in particular, and integration with longstanding “industry-standard” SW and HW (Avid, Protools, Nuendo, etc.) to make Bitwig usable in the industry (moving resources back and forth in post) is likely not worth the design changes it would require. Also, coming from a film post audio editing/mixing background, working with Bitwig was a very different experience than film post (unless you are actually composing for film). For example, the clip launcher is still alien to me.
Dolby concerns are real, especially with ATMOS, but with other formats, in particular 5.1, 7.1, etc., the Digital Cinema Standards for audio delivery is standard individual WAV files for each channel. No longer is AC3 format required; so no Dolby. Many plugins exist for metering that respect Dolby and ITU standards and are used to mix film sound. Many post houses will send the mix off to have it formally tested/certified without having to have their own Dolby-certified facility, if that is required for the release. ATMOS will undoubtedly require licensing to do certain things, although it appears Dolby is trying to make things less painful than in the past. Being able to route channels beyond Stereo would be a nice addition to Bitwig, simply from a sound design aspect, even if output were to 6 or 8 individual WAV files.
If it were easy, there would be no Cubase AND Nuendo. DaVinci Resolve’s audio editor, the venerable Fairlight, doesn’t understand MIDI, or use VSTi’s effectively for sound design. Neither does Adobe’s Audition, although it is pretty good at handling 5.1 sound mixing with video support. I’ve used Audition to create and mix 5.1 surround for short films ultimately to a Digital Cinema Package (DCP) that digital theaters require, all without Dolby’s interference. But since it doesn’t understand MIDI, I had to use existing Audio files as my raw materials.
Having said all that, I DO believe, that just having video support (with typical video frame rate timeline support) even in Stereo to allow for Composing for Film would be a HUGE advantage in giving Bitwig a toehold on the lucrative film post market. Most music in film appears in Stereo (at least that’s the common advice), although with ATMOS, music may be spreading rearward.
So, my wish is for video support to include timecode fimelines (instead of beats/bars) at least in Stereo for starters to permit composing music/atmosphere to film. Adding multichannel support like 5.1, 7.1 (ignoring ATMOS atm) and output to individual WAV files per channel would round things out. Neither would require the significant amount of retooling that would be needed to integrate Bitwig in the existing industry post workflows, but could provide the necessary assets to import into proper film post DAWs. Video support could be nothing more than reading MP4, and perhaps pulling out a track of dialog for reference on the timeline. My two cents. Loving Bitwig!
