Basic Scene Setup for a video player no lighting

Your video files should be stored in the Assets folder for this procedure.

FFMPEG
Use ffmpeg to encode h.265, windows DOS script for a batch file:
set dt="%USERPROFILE%"\Desktop
set tiffs=-framerate 30 -start_number 1 -i F:\tiff_filename.%%04d.tif -pix_fmt argb
set loopend=1000
set codec1=-vcodec libx265 -x265-params bitrate=20000:vbv-bufsize=8000:vbv-maxrate=25000 -pix_fmt yuv420p -movflags +faststart -pass 1
set codec2=-vcodec libx265 -x265-params bitrate=20000:vbv-bufsize=8000:vbv-maxrate=25000 -pix_fmt yuv420p -movflags +faststart -pass 2
set sp=1
set output=%dt%\filename
ffmpeg.exe -y %tiffs% -frames %loopend% -filter_complex scale=iw*%sp%:ih*%sp%,setsar=1 -r 30 %codec1% -f mp4 NUL
ffmpeg.exe -y %tiffs% -frames %loopend% -filter_complex scale=iw*%sp%:ih*%sp%,setsar=1 -r 30 %codec2% -f mp4 %output%.mp4
del ffmpeg2pass-0.log


I have am using bitrate=75000 and maxrate=80000 on a project, it works great.

Republish your player

BUG work around
Unity sometimes resizes or changes the player window, and saves the changes to the Registry
Create a batch file to run your player on your desktop, name it RunBuildAndFocus.bat, add the following script.
Double click to start your player.

@ ECHO OFF
start "" C:\Users\%USERNAME%\Desktop\unity_player_folder\unityplayer.exe -screen-fullscreen 1 -screen-height 1200 -screen-width 1920 TIMEOUT /T 10



If you are having trouble with the window of the player, the corrupt Unity files are here:
Use Run, type regedit
delete Computer\HKEY_CURRENT_USER\Software\DefaultCompany\projectname
