For optimal performance… its recommended to rotate your playfield videos if they are 180 degree rotated. Or if you have 4K screens… why bother and make brand new 4K30fps playfield videos :)
also, with the autorecord feature you can have Popper automatically create all new 'fresh' media that will make the front-end run a lot smoother than using your older media. See here:
create a temp folder somewhere and copy all your playfield videos there.
grab this file: http://www.nailbuster.com/pup/Rotate180.zip
unzip into your temp folder
run the batch file (rotate_180.bat for 180 degree) and it should create a sub_folder and start converting/rotation all files for you automatically. THIS MAY TAKE A LONG TIME if you have alot of files, so maybe run overnight or something if you need to. Batch file is setup to do mp4s. but if you look at batch, you can very easily change it to *.flv or *.mov (other video filetypes) and re-run batch.
BTW: If you have a pin2k cabinet the above method is the same, but instead of running the rotate180.zip you use this one to flip Y access on dmd videos.
Also, for REAL-DMD users, only animated gifs are supported (no avi/flv).
If you have a real-dmd, the above method is the same, but instead of running the rotate180.zip you use this one:
try this batch to convert them to animated gifs: (experimental) http://www.nailbuster.com/pup/make_anigifs.zip
within the batch you can see the resolution of the GIF output.
