HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload your THP file
Drag and drop a .thp video extracted from a GameCube or Wii game, or select it from your device.
02
Convert to MP4
Keep MP4 as the output format and start. The JPEG-based video becomes H.264 and the THP-ADPCM audio becomes AAC.
03
Download the MP4
Download one MP4 per THP file. It plays in browsers, on phones, in VLC and in video editors.
THP
THP is Nintendo's video format for GameCube and Wii games, used for intros and cutscenes. Each frame is stored as a JPEG picture, usually with THP-ADPCM audio at 32 kHz. Phones, browsers and most video editors can't open it.
MP4
MP4 is one of the most widely supported video containers for web, mobile, social media, presentations, and everyday playback. It balances quality, compatibility, and file size well when paired with common codecs.
FILE FORMATS
SOURCE
THP is Nintendo's cutscene format for GameCube and Wii games. Each frame is a JPEG picture and the sound is Nintendo's THP-ADPCM, which keeps decoding cheap on console hardware. Games such as Metroid Prime, Super Smash Bros. Brawl and Mario Kart: Double Dash!! use it, and only emulators and specialist tools play it.
TARGET
MPEG-4 Part 14 is the default container for phone recordings, web video and streaming. MP4 with H.264 video and AAC sound plays on iPhone and Android, in every browser, on smart TVs and in Windows and Mac players without extra codecs. It holds text subtitles and chapters, but not picture-based subtitles.

USE CASES
Practical workflows where THP to MP4 conversion is useful.
Watch GameCube and Wii cutscenes on any device
Play THP cutscenes on a phone, laptop or TV without setting up an emulator.
Edit cutscenes into a retrospective
Use the MP4 in Premiere Pro, DaVinci Resolve or CapCut for a retrospective, review or story recap video.
Share a scene on Discord or social media
Post a favorite GameCube or Wii cutscene where an MP4 plays inline, such as a Discord chat or a social media post.
Show a game's intro on a fan site
Fan sites and wikis can offer a game's intro or ending as a normal MP4 that every visitor can play.
Check a custom THP for a mod
Modders who make replacement THP videos can convert them back to MP4 to check the picture and sound before testing the mod in Dolphin or on a console.
Compare NTSC and PAL versions
The MP4 keeps each THP's own frame rate and size, so cutscenes from different regions can be compared side by side.
Keep watchable copies of game videos
Convert the intro, credits and cutscene videos from a game disc into MP4 files that open on any computer or phone.
Use cutscenes in a talk or class
Insert a THP cutscene into PowerPoint, Keynote or Google Slides for a presentation on game history or design.
Study cutscenes frame by frame
Every frame is kept, so you can step through the MP4 for speedrun notes, animation study or fan art references.
Salvage a partial THP
A THP that was cut short, such as a partial extraction, still gives the frames it holds, so you can watch what is there.
SUPPORTED FILES
THP videos from GameCube and Wii games are supported.
Both versions convert.
Video-only THP gives an MP4 without audio.
Becomes AAC at the same sample rate.
Still give the frames they hold.
Upload many THP files and download the MP4s as a ZIP.
Only convert videos from games you own or have permission to use.
TROUBLESHOOTING
Game videos have a few quirks.
01
THP frames use full-range color. This converter changes them to standard TV range, so every player shows the same colors.
02
H.264 needs even dimensions, so an odd width or height is rounded down.
03
The THP had no audio track. Many games play cutscene music separately.
04
If a THP holds more than one audio track, the first is used.
05
The file is damaged or not a THP video. Extract it again from the game disc.
06
Check the file came from a GameCube or Wii game, not another format named .thp.
Emulators, FFmpeg builds and tools such as VGMToolbox can play or dump game videos once set up. dragdropdo turns THP into MP4 in the browser, ready to watch or edit.
