What is an OSR File?

An OSR file is a game replay file generated by the osu!, a free-to-play rhythm game where players click circular objects in time with music. These clicks are scored based on their timing and accuracy. At the end of a song in osu!, players have the option to save a replay of their playthrough. This creates an OSR file which saves details of the gameplay sessions like the player's name, score, number of hits and misses, the date played, and ranking on the leaderboard.

OSR files allow players to rewatch and share their replays with others. However, to view an OSR replay properly, the recipient must have the corresponding beatmap file in the "Songs" folder and have osu! game installed. OSR files are not standalone, and can only be viewed within the osu! game engine. Therefore, they are not compatible with most media players and platforms. Many osu! players wonder whether it's possible to convert their OSR replays into MP4 video files, which can be easily shared and viewed. The answer is YES, keep reading!

OSR Replay Recording

HD Video Converter Factory Pro incorporates a "Recorder" module, offering a dead-easy way to record your OSR replay to MP4/AVI/MOV/MKV with high quality. More surprisingly, you can even edit and convert your recording with ease.

How to Convert OSR Replays to MP4?

There are two primary methods for converting OSR replay files to MP4: the osr2mp4 app and the free online tool o!rdr. Let's take a closer look at each method and discuss their pros and cons.

Method 1: Using osr2mp4 App (Still Work, But No Longer Maintained)

The osr2mp4 app is a Windows-based application designed to convert osu! replays to MP4 videos in a few clicks. Though the final version of this app stops at v0.3 and has not been updated since 2020, it still works during my hands-on test. Keep in mind, there is no guarantee of success that osr2mp4 app is compatible with newer operating systems and game updates. If you want to give it a try, follow these steps:

Step 1. Download the osr2mp4 RAR file based on your system type from the GitHub repository. For a very old PC, choose the legacy version.

Step 2. Unzip and extract all files, then run the "osr2mp4.exe" executable file.

Step 3. For the first time use, you're prompted to choose your osu! path and output folder. If not, just open "OPTIONS" window to change them. By default, it will save the output file in .avi format. You need to change the video format manually after the conversion. Alternatively, you can directly change the file extension from .avi to .mp4 under "Output name" section.

Step 4. Click "SELECT .OSR" button to locate your OSR file that you want to convert.

Step 5. It will automatically search for the beatmap. So most of the time you just need to select the replay file.

Step 6. Finally, click "START" button to initiate the conversion process.

Note. osr2mp4 app only works for standard game mode. It doesn't convert OSR replays of the other 3 game modes: taiko, CTB, and mania.

Method 2: Using o!rdr Online Converter

o!rdr (short for osu!render or osu!renderer) is a free online tool that can convert osu! replays to MP4 videos without the need of downloading any software. Here is how to use o!rdr to convert OSR file to MP4 online:

Step 1. Visit o!rdr via THIS LINK.

Step 2. Click "Pick a replay" to add an OSR file.

Step 3. Enter your username and choose a preferred resolution. You're allowed to link your osu! account to enable 1080p option or donate to o!rdr for unlocking 4K option.

Step 4. Customize Gameplay settings, Skin settings (required field), Cursor settings, Objects settings, Other settings, and Video settings.

Step 5. When everything is ready, click "Send render job" button. Then your file will be uploaded and processed.

Step 6. After done, it will give you a video URL to play and download the MP4 file.

Note. Like osr2mp4 app, o!rdr does not support mania/CTB/taiko game modes either. The conversion speed and quality may vary depending on the modified settings, the server load, and your Internet connection. You may also see an error message that says "Too many requests, please try again later." or run into the unexpected long downtimes.
