Oi! Dun copy me! D: LOL
You mean AviSynth, yes? There is this thread
I will give you a simple script for a SNES gaem.
If I remember correctly, Super Mario RPG has 5 parts.
pointresize(width*2,height*2) # Double-sizes the video (320x200 -> 640x400)
SubsStart=50 # set to 25 if you recorded at 25 fps
SubsDura=250 # set to 125 if you recorded at 25 fps
Subtitle("GameName", first_frame=SubsStart, last_frame=SubsStart+SubsDura, y=408, size=24, text_color=$ffffff, align=2)
Subtitle("PLAYED BY YOURNAME", first_frame=SubsStart, last_frame=SubsStart+SubsDura+5, y=428, size=24, text_color=$ffffff, align=2)
Subtitle("www.LONGPLAYS.org", first_frame=SubsStart, last_frame=SubsStart+SubsDura+10, y=448, size=24, text_color=$ffff00, align=2)
ConvertToYV12() # Converts to YV12 colorspace for h264
Copy and paste in a AVS file. It will make more sense.
Substitute "videofilepath" with the path of the video file (example: C:\something\something\something\filename.avi). If you need to append more, just add moar AviSource and +\.
As for subtitles:
For SubsStart and SubsDura, I say change 50 to 60 for SubsStart and 250 to 300 for SubsDura (they are NTSC framerates. I guess use on NTSC games aka US and Japanese games).
Adjust y value to move the text. (Dun have a SNES script since I had to re-install XP, but that's not the point).
After making the changes, drop it in something like VLC or VirtualDub (I prefer VirtualDub just for the sake of finding frames to "trim" out).
Once done messing around with the settings, get MeGUI and make your video and audio files (video with x264 and audio with Nero AAC.).
For simplicity's sake, encode as MP4 files (be sure to name them differently. I usually add an "a" to the end of the audio file with the same name as the video file. Example: SMRPG for video and SMRPG-a for audio).
After that, mux them in MeGUI for the giga file to be uploaded to the FTP. Don't forget to get the text here
. (it also has moar info).
I might edit some moar so keep [d]F5'ing[/d] checking for a change in the post.
For "Precise file size", that would be Size when you Right-click and choose Properties (I think). Copy the bytes section. It makes it a bit easier on the people who input the information.
-Play with AVS file until happy.
-Give MeGUI the same AVS file to make a video and audio file.
-Enqueue and waste time
-Tools -> Muxer -> MKV Muxer (or MP4. No real change in quality, really)
-Load to FTP
-Get past quality control
-CELEBRATE!!! =D (cake MAY be included)
Pro Tip: when uploading to FTP, be sure to set default file exists action to "Resume" (Transfer -> Default file exists action. Change Uploads to "Resume")
