[Questions] Automated script generation
I'm getting ready to setup a super plex encoding server for fun. One of my goals is to, as much as possible, automate the process.
So here's my plan of attack, tell me if it's crazy. Use ffmpeg's interlace detection to figure out if a video has interlacing. Use ffmpeg's black bar detection to find black bars Do a test noise filter. Use something like KNLMeansCL with a high strength setting to and do a comparison between input and output to see if there's a big difference. I'm thinking something like VMAF would be good. My assumption (Would this be wrong)? is that noisy videos would have lower VMAF scores than clean videos. Is that true? Would there be a better way to score noise of a video? Assuming all that works correctly. Go off and generate an appropriate vapoursynth script. (Adding and removing filters based on what was previously detected). So, my question. Which noise filters should I be looking at? Which deinterlacing filters should I be looking at? Does it make sense to try and split a video's frequencies and denoise specific frequencies? (For example, I've seen videos where whites seem to have a ton of noise whereas darks not so much). Are there tools I'm overlooking? |
