Hi,
I just discovered the DirectShowInput driver and have already successfully opened MKV's containing AVC and VC-1 streams from my BluRay sources. I don't see any negative impacts or anything, but I was wondering if there are any issues I should be aware of when loading files into virtualdub like this?
I'm not using FFDshow, but I am using LAVfilters. I mainly need to open certain files I wish to filter with NeatVideo and potentially some other filters, and then export to an intermediate lossless file for encoding with x264.
Do I have to worry about weird artifacts being introduced, or things like that happening? Will there be any issues with Vdub colorspace conversions? |

The usual problems/gains of using the systems codecs and splitters
One thing I have noticed is that sometimes mp4's phut out and the audio stops being decoded -> remuxing to mkv always seems to make the same files work though
You might want to change the video menu->colordepth to one of the YUV's to avoid a rgb<>yuv conversion though
The alias format filter will let you swap between native 601 and 709
(of course your choice of filters may force an rgb conversion anyway)

Yeah, I use Neat Video which filters in RGB anyway, so I just throw a convert to YV12 filter on after that. |
