Since you are on a PC you can use
Steven Selph's scraper. The videos WILL work on a PC however you will have to compile it but it will work.
You just have to batch encode them with handbrake you can do that from the command line I did a "full" batch of videos for arcade for my pi. (The pi doesn't like 60fps @ 640x480...heh.) The scraper works but it brings down unusable videos. Just let in run over night or while at work. Or create a batch file and run that.
Here i did it for you This will convert them with the x264 encoder to a size of 640x480 @60fps with a volume drop of -20:
1. Copy it to the folder you have your videos located
2. Open it in
notepad 3. change the output paths using search and replace
4. change -o path/ to the output folder you want (e.x. create an output folder inside the folder your videos are in)
A. open the empty folder you want your videos to go in and then copy the path from the bar at the top and paste it into the "replace with" bar.
5. So now you have for
example -o /arcade/videos/output/ (yes you need the -o and space! and the ending /) in the replace with box.
6. then click replace all
7. then save the file
8. now double click the bat file or
run from the
command line a. Press windows key+r
b. Type cd then the path to your videos folder (the folder you dropped the bat file into copy it from file explorer and then into the command window if you want) ex.
cd games/arcade/videos
then type
clihandbrake.bat
press enter
if it throws any errors let me know (copy and paste it here (and note double clicking it will not produce and output if there are errors )) you can stop it by pressing ctrl+x
note not all videos will be found to convert..this is normal.
[Took me longer to type all that then it did to make the batch file!
