Pyjom Schedules

This article features discussions on various video and audio processing projects. These projects cover a wide range of tasks such as Natural Language Understanding (NLU), trending topic discovery, loudness improvement, watermark removal, enhanced highlight algorithms, voice changing technology, locating older content, and live streaming for quality enhancement.

dog/cat video generation

make render engine runnable

issues:

  • video length too long (10 mins)

it was the speed calculation error.

  • bgm somehow not in sync (too broad bpm/clip ranges?)

  • to analyze the peaks (abrupt changes) in bgm and grab louder peaks using pyloudnorm (getting audio volume)

pip3 install pyloudnorm

import soundfile as sf
import pyloudnorm as pyln
data, rate = sf.read("0055014.wav") # load audio (with shape (samples, channels))
print(data.shape)
meter = pyln.Meter(rate) # create BS.1770 meter
loudness = meter.integrated_loudness(data) # measure loudness
print(loudness)

  • place video on loudest points, abrupt changes detected by talib or just take direvative and gaussian average

  • video too repetitive (small corpus?)

  • do not remove subtitle and crop active region (reviewer’s resource not used? but i rather advise you to do it directly since it requires less computational power)

  • do not have minimum motion threshold (reviewer’s fault? also recommend you to do this in producer)

  • remove all watermarks, subtitles and crop video boundaries accordingly

  • source video and audio (infinite, basic test is to find 500 sources at once without duplicate, second test is to find 500 second is to find 500 without duplicate twice), improve highlight algorithm

  • find 500 songs without duplicate at once

  • find 500 songs no duplicate twice

  • find 500 animal videos without duplicate

  • find 500 animal videos no duplicate twice

  • generate appropriate title, cover, info and tags

  • collect feedback after the post

  • find some shocking fonts for cover and subtitle, english and chinese

  • make that karaoke effect

  • make ass with karaoke effect with lrc files

  • make lyrics sync logic fluent, according to what have learned from karaoke effects

  • make selected video clips fluent, no abrupt cuts, maybe we need pyscenedetect?

text to video, template based video generator (this is perhaps the most complex video generator ever. do it with caution, it might also includes the flipcard, narrator and slideshow based generators)

generator models subarchitecture (subcategories of template based generators)

flipcard

slideshow (video and audio, might also include the dog&cat video!)

narrator

summarized video

policy evasion, NSFW filters

  • remove all hints from image, video, audio and script that may lead to copyright issues

analyze the media content and metadata, relationships

index, retrieve and align video and audio content according to our collected database
