- v2pLFN is the v2project own lossless video format, it's design for intermediate format, not as final media.
- here are not good for:
- very large amount of space, because doesn't have inter-frame reuse techniques.
- for 1920x1080 32bits mode, almost 1.5MB/frame, for 24FPS 45MB/second
- similar to APNG but smaller and simpler, can work on USB 2.0
- lot of read and write IO.
- without multimedia instruction set optimization of the processor, still not fast, yet.
- decode nowhere, no other way to playback.
- here are good for:
- very fast seek, because indexed as map, is random access not sequential access, direct turn to image even file breaked.
- playback in any direction, because without inter-frame reuse techniques, so no need to decode parent/key frame before.
- never loss of quality, without motion blur, all frame are photo level.
- 4x8 bits colors, RGB8888 color format.
- friendly any CPU, because without motion compensation. for example ARM v5, STM32 or even 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.
- like JPEG, since inter-frame reuse is the focus, and encoders strive to make one frame as identical to the next as possible, each encoding of video loses few video information.
- for color formats such as yuv420, the color will be lost, which is not friendly to high-chroma video sources including digital 3D video.
- try high bitrate with yuv444 color format almost lossless.
- v2pLFN only recommend for intermediate format as effect result, you can process the effect video easily use for other video, such as text effects, emoji effects.
- you can use v2pLFN/v2pLFNA for v2mixer, convert back to other format any time.
- examples: build emojiv2pLFN
- 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
