The other thing is that DirectShowSource is known not to be frame accurate per se, in the sense that it might randomly skip frames as well.Ī quick example would be to move through the script using AVSPmod and trying to focus on a few frames going back and forth several times: it's almost always the case that as you get back to where you were before, you're not gonna see the very same frame.
Well, it relies on the decoder, so it relies on the codec installed and whatever decoder is using, so that's a thing. When you said that it's not gonna be frame accurate does it mean with every kind of frame rate or only with drop frame rate like NTSC ? So, in a nutshell: yes, it can be done, no, it's not implemented by default for a reason: DirectShowSource and the fact that you would have to install a codec anyway.Īs I understand directShowSource could be used like the Quicktime ref Avisynth decoder for FFAStrans ? I think it would be way better to link and transcode it using a NLE like AVID Media Composer, Davinci Resolve etc as that's the way the official codec is supposed to be used and you will be able to choose the settings and use all the benefit of that codec. To decode them, you're gonna need to install the official RED Codec Package provided with your camera and then use an Avisynth Script to decode the files you pick with something like DirectShowSource("myredfile.r3d", audio=true) but:Ī) It's gonna be limited to a small number of color spaces and 8bit onlyī) It's not gonna be frame accurate, in the sense that it might drop frames every now and then due to DirectShow itselfĬ) You're gonna lose all the metadata and it won't apply any kind of LUT or anything to your file So, as long as you're gonna be able to decode those files in the Operative System, you're gonna be able to use DirectShowSource. It's literally just asking the Operative System to use whatever codec it has to decode the file and then "pipe" the output to Avisynth so that it can be used in the frameserver. There isn't an open source indexer like LWLibav or FFMpegSource2 that can index them, however you can use a "workaround" with DirectShow.ĭirectShowSource basically uses the built-in DirectShow of your OS (Windows) and opens it in Avisynth as frameserver.
r3d are raw files with a proprietary codec made by RED specifically for NLE like AVID etc. r3d files, there's technically a way to index them, but it's not gonna be frame accurate.
