v2mixer v2pLFN - v2Mixer official

overview
- v2pLFN is the v2project own lossless video format, it's design for intermediate format, not as final media.
  - for cut + effect export to part A, then part B, will join as video C, if part A/B lossless, the video C will never lose the quality.
- here are not good for:
  - very large amount of space, because doesn't have inter-frame reuse techniques.
    - for 1920x1080 24bits at 24FPS, default level almost 42MB/second, USB 2.0 max.
  - lot of read and write IO.
  - without multimedia instruction set optimization of the processor, slow yet.
  - frame random, on decode the random file access(range if http) is required.
  - decode nowhere, no other way to playback.
- here are good for:
  - very fast seek, because indexed as map, not sequential access, direct turn to image even other part breaked.
    - frame uncorrelated, parallel encode/decode allowed.
  - playback in any direction, without inter-frame reuse techniques, no need to decode parent/key frame before.
  - never loss of quality in 4x8 bits colors, ARGB8888 color format.
  - friendly any CPU, including MIPS, ARM v5 even STM32 etc. lower power processors.
  - keep transparent information, can use as effect result without Chroma key.
    - if the project background alpha channel not 255(0 to 254), the format will v2pLFNA, with transparent supported.
- you can use v2pLFN/v2pLFNA in v2mixer convert back to other format any time.
examples: build emojiv2pLFN and resue any time.
- new project
- click the background color, input 0 to Hex, click OK to create a fully transparent background
- add video, setup the effects such Effect Image Mask
- exportas v2pLFN
- the v2pLFN result will fully transparent, you can use any other video as emoji
