I'm looking for an efficient format, and therefore would be lossy and interframe (temporal) compression. Sorry again for not specifying enough information. How about a separate alpha channel? You can use h264 temporal compression YUV422 + h264 YUV420 temporal compression alpha. Not very many editing platforms support YUV444P8 or P10 FFV1 does, but again limited support for editing, and it's lossless (although it offers lossless temporal modes). x264 supports it as AVC, but no professional editing application supports that RGB version. Not very many RGB temporal compression formats available. VP9 native supports YUVA420P8, but it's very poor support for ingest and editing. Even the lossy codecs like prores, cineform, grass valley hqx, etc. All intermediate formats are intra only, thus the large filesizes many times larger than what you are looking for. It's impossible to use intra only on typical content unless you're dealing with very simple content like 1 or 2 color graphics or simple toonsīut Long GOP / high compression is for end delivery, not intermediate post production. 1920x1080 20-25Mbps means temporal compression. I appreciate any help or recommendations on greatly helping with this workflow! And even so, I imagine the bit rates are still too high. Apple's ProRes4444 supports alpha channels, but unfortunately it is not supported for Windows - at least for encoding.
I've tried common formats that support alpha channels, such as Microsoft's AVI, QuickTime Animation, and GoPro CineForm, but they're all terribly inefficient (ie.
Even better if it works across all of Adobe software (Media Encoder, Premiere) and beyond (Cinema 4D, DaVinci Resolve, etc). Also, it'd be great if this plugin worked specifically with Adobe Premiere to render and encode directly, rather than to transcode and convert after After Effects. This would be an intermediate format (not delivery), so widespread support on devices is not needed. Ideally, I'd like like a format that's "high quality" (minimal blocking, banding, noise) at 20 - 25 Mbps with RGB+A at 10-bit 4222 (or even 4444) at 1080p, but with options for interframe/intraframe, CBR/VBR, progressive/interlaced, various aspect ratios, 4K+ resolutions, etc. However, file sizes are ridiculously large (1 GB for 20 seconds at 1080p), and I'm looking to trim that by using a more efficient format within After Effects.ĭoes anyone know of a plugin for After Effects for a codec/format that has a RGB+A with similar efficiency as H.264? Often, 10 Mbps is sufficient for most YUV420 8-bit material with H.264, so I'm looking for something similar with an alpha channel. Often, there's a need to export content with alpha channels (transparency) to various editing platforms for other (human) editors for projects. I'm looking for a solution to a data bottleneck in my VFX/compositing/animating workflow with Adobe After Effects.
