• what's the professional standards of v2mixer?
  • is not mean profession than other software. mean for profession, for example change the color, software A have many scaler to change it get more light, saturation, or more cool or hot.. for user doesn't have the plan, just roll for some may good feeling. because as normal user, he/she doesn't need to known about alpha, RGB, HSV, 4000K, 9000K, DPI.. but an profession user, v2mixer open that all for more possibility.
  • so v2mixer for player may don't known what it can do.
• how can i reload the file used in project?
  • for example the content of subtitle file i changed, but v2mixer never ask reload. because v2mixer doesn't watch the user file, you have to try revert way: Save the project, then click Revert(at the left panel Tool menu) to reload the project.
• can i move the media file that already as export job in or wait for running?
  • no, you will got job failed if you move the media file already as project resources before the job done.
  • the media file you used for project resources(video chapter for example) without export, then you move that file, next you open that project, will dialog for you to repair them. so you have to remember where you move to.
• about v2mixer input box, I don't even know how to input the text?
  • v2mixer use the v2projectUI framework, paint all without Window Manager. so may feel a little uncomfortable. with locale input method, you just type, the result will show in the input box.
  • anyway, you can hold the CTRL then press X for delete(cut) them all, then inputagain, or CTRL+V paste the text you type elsewhere.

• when i upgrade new version, the project file i save is still work?
  • yes, but new key of effect will keep default value and some key we patch as new algorithm will not effect the project, for example:
    the Effect Image Mask, the result shape already count when you click the OK, mean shape also save in the project file.
    • even new version change the algorithm but shape still unchanged.
    • because v2mixer don't known which one is you want. in v2mixer original design, Effect have to keep last user saw if that can.
    • so if you want update the effect to new algorithm, just click that "OK" button again, without change anything.
• the codec is also save in the project, what happen when i remove the chips?
  • in v2mixer original design, most do keep the last you saw if that can.
  • so yes, the codec you last using for decoder(including Effect Decode Codec)also save in the project. after the load the v2mixer will check the chips still available.
  • so you can share project files to friend with a completely different hardware environment.
• how can i packagethe project and files to my friend, or move to my home?
  • the file used for project, will save the path in the project file.
  • for example project file d:\myfile\project1.v2mx, used d:\prj1\1.mp4and d:\prj2\2.oggfor layer, and e:\images\2.pngused for Effect Image Mask
  • when i send project1.v2mxto my friend. my friend want to open the project file, that three files also must exist in that path? we have two solution:
    1. you can send three files too, v2mixer will dialog an repair window if a file can't read, your friend can select the file in new location to fixed.
       so yes, if you use c:\users\my_name\my videos\2.mp4, this path also save in the project, and will show in repair window, because path have your user name, may not you want. so please don't use the personal path if you want share the project.
    2. you can put three file same folder of project1.v2mx, then used for the project, when load the project1.v2mx, the v2mixer will try load absolute path, if failed, will check as relative path, if the file is same or parent of the project file, even your friend work on macOS or Linux but you not.
       for example, d:\myfile\project1.v2mx, d:\myfile\video\1.mp4, d:\myfile\video\2.ogg, d:\myfile\2.png, because all file same or parnet the directory of d:\myfile\project1.v2mx, you can just package the d:\myfile as zip to your friend, your friend open will work correctly without repair.
  • one of file in the my personal path (c:\users\my_name\my videos\2.mp4) already use for project1.v2mx, how can i change to without my_name before send to my friend?
    just move that file to somewhere, open the project file, repair, save the project, the project will update to new path.
• in v2mixer\temp directory, what's that, can i remove?
  • y, that are temporary files, will create next start if need.
  • jni\ is the library file use by v2mixer.
  • job\ is the queue file, remove may lose incompleted job.
  • awf\ is the waveform cache file, will remove when it project file not exist.

• the audio output i'm in linux, lock my sound card?
  • on linux, v2mixer use the ALSA, v2mixer may(if alsa handle by other agent, such OSS, PulseAudio) lock the sound card for output, you other application(or the v2mixer) may no sound.
  • so if you are use the PulseAudio, alsa-plugins is required to install, it will handle the v2mixer without lock and let you enable the volume control.
• i play the 6 channelsaudio in Editor player(the left player), It seems that some channels doesn't work?
  • in short, whatever current audio output device channel/frequency/bits its,
    • in Editor(the left player), always work as max of device supported, just like other video player.
    • in Program(the right player), always output full channels after Effect Channel Map, if device doesn't support, ignore.
    • in Exportalways work as project setting, doesn't care the hardware.
  • i have 6 channels audio device, play 2 channels audio:
    • in Program, depends Effect Channel Map, for example:
      • map it to 2, hear stereo.
      • map it to 6, hear 6 channels audio
      • map it to 8, hear 6 channels, the channel 7 and 8 ignored. 
        • in Export, with all channels data.
  • i have 2 channels audio device, play 6 channels audio:
    • in Program, depends Effect Channel Map, for example:
      • map it to 2, hear stereo. this is the project default setting.
      • map it to 6, hear 2 channels, the channel 3456 ignored.
        • in Export, with all channels data.
  • Note1: output device above is before the OS mixer(included), some OS mixer may accept all Hz and any channels.
    • for example, PulseAudio for Linux (with alsa-plugins, handle the ALSA) accept any Hz, 32 channels, then mixer to hardware, may 2 channels.
      • but map as 6 and play in Program got unexpected result, you may don't known which part problem.
        • because 2 map to 6 by v2mixer, then 6 map to 2 by PulseAudio.
      • this example also happen in some mixer handle by video driver(HDMI output)
