vfr.py ====== Inspired on: Daiz's AutoMKVChapters, TheFluff's split_aud, BD_Chapters Needs: Python 3; MkvToolNix (for audio trimming) What it does ------------ * Reads the first line of uncommented Trims from an .avs; * Uses timecodes files to get each trim's frame's timestamp; * Offsets the trims accordingly; * Creates a basic xml with Matroska chapters, x264 chapters if ending in 'x264.txt' or OGM chapters if any other extension is used; * Creates a qpfile to use with x264; * Cuts and merges audio (as per split_aud, only using v2 timecodes instead of expecting cfr) (all options work as split_aud); * No longer needs tcConv but converts v1 timecodes to v2 internally; * If requested, can output v2 timecodes from v1 and fps parsing. If --ofps is being used, v2 timecodes will use it; * Can output a qpfile with converted frames meant to be used for an ivtc'd encode using non-ivtc'd frames (feature inspired by automkvchapters) (not completely accurate, obviously); * Using FFmpegsource's CorrectNTSCRationalFramerate, this is actually more precise in the v2 timecodes it produces than tcConv; * Accepts AutoMKVChapters-like templates. Only the .avs with trims is required for vfr.py to run. You can use -v and/or --test to debug the script. All other options and arguments are optional. Usage ----- vfr.py -i audio.aac -o audio.cut.mka -f 30/1.001 -l tRim -c chapters.xml -t template.txt \ -n chnames.txt -q qpfile.qpf -vmr --ofps 24/1.001 --timecodes v2.txt --test trims.avs outtrims.avs Required: trims.avs = Gets first uncommented line starting with trims from this Avisynth script Optional: -i = Audio to be cut (takes whatever mkvmerge takes) -o = Cut audio inside .mka Default: input.cut.mka -d = Manually set delay time for input audio (can be negative) -b = Reverse parsing of .avs (from bottom to top) -f = Frames per second or timecodes file if vfr input (takes "25", "24000/1001", "30000:1001", "24/1.001" and "30:1.001" as cfr input) Default: 30000/1001 -l = Look for a line starting with a case-sensitive trim() or case-insensitive comment succeeding the trims, interpreted as a regular expression. Default: case insensitive trim -g = Specify directly the line used -c = Chapters file. If extension is 'xml', outputs MKV Chapters; if extension is 'x264.txt', outputs x264 Chapters; else, outputs OGM Chapters -n = Text file with chapter names, one per line; assumed to be UTF-8 without BOM -q = QPFile for use in x264; will use --ofps frames -t = Template file for advanced Matroska chapters -v = Verbose mode -m = Merge split audio files -r = Remove split audio files after merging --clip = Only pick trims that are using this clip name. Ex: ClipX.Trim(0,1) or Trim(ClipX,0,1) --uid = Set base UID for --template/--chnames --chnames = Path to basic text containing chapter titles separated by newlines --ofps = Output FPS (used in qpfile, v2 timecodes and avs export) Default: -f --timecodes = Output v2 timecodes (from fps and v1 parsing) (if using --ofps, outputs v2 timecodes using this) --sbr = Set this if inputting an .aac and it's SBR/HE-AAC --test = Test Mode (doesn't create new files) outtrims.avs = If chapparse.py is present, outputs .avs with offset and converted trims To do: * Optimize code and/or improve its legibility Known issues: * Conversion from a different input fps to output fps is not accurate (probably no way it can ever be fixed)
