[Offtop] Neural networks image upscale for cinelerra

29 Nov '22

Hi, Neural network assistant image upscaling has been a trending feature for a few years. I've found an interesting pre-built executable here: https://github.com/xinntao/Real-ESRGAN#portable-executable-files-ncnn (no python needed). I wonder, if cinelerra can use external filters like that to upscale video? Best regards, Andrey

offtopic: proprietary software making BD from HDV
by Andrew Randrianasulu 22 Nov '22

22 Nov '22

so according to link below it was possible in 2010 or so. thing is apparently new versions remove this feature because you know, 'progress'! https://www.vegascreativesoftware.info/us/forum/hdv-to-blu-ray-why-is-it-re… I think technically it completely possible, just need some coding thinking. Terje, can you check if 'native mpeg' decoder still works for HDV specifically? (toggle Use FFmpeg first icon/button in main window and then load your file(s) ) I think it was working in cinelerra 2.x times because people edited HDV back then and ffmpeg was little decoding library inside libquicktime folder for some mov/avi decoding .... may be developing mpeg2 video elementary stream direct copy will be a bit less of Task compared to more generic case? At least libmpeg3 already know how to create index file, so info about keyframes and GOPs all should be there ...'only' problem I never dived that deep into real inner workings of encoder (some forum post suggest you need to edit at *field* boundary, not frame boundary, and this complicates things a bit), and one bit set wrong there obviously can make file unplayable :(

possible alpha bug in processing
by Andrew Randrianasulu 22 Nov '22

22 Nov '22

User 'goat' reported cingg failed to create png sequence with alpha, even if proj set to rgba and png settings also include alpha. I ..spend a lot of tume in filepng and fule, until it dawned at me Ican check older cingg! Bug was not there in june 15 2020 selfbuild. And bug was present in 09 30 2020 ubuntu 16 static tar ... So I searched git log and found this commit https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blobdiff;f=cine… i tried to set alpha to 0 (zero) in virtialvconsole and suddently pngs and exrs and tgas got their alpha back! How to check: Load video into cingg Set format to rgba-8 bit Set Alpha plugin over video, with parameter 0.5 or use fader. Set output render to one frame, png, use alpha. Render While image will be with right format alpha will be absent as evidenced by gimp's colorpicker. patch cingg with attached patch, hope alpha will be back! But of course we better to re-test video formats with alpha too ... (just not sure how) note, ffmpeg's png encoder worked ok, and so did tiff encoder. But png/exr/tga were all busted wrt alpha.
