Working with MP4 Video in DJ.Studio
Working with MP4 videos can sometimes be tricky, as video processing performance depends heavily on your device — both in terms of hardware and software — as well as the specific MP4 file you’re using. This means that certain issues may only occur on specific setups and can be hard for us to reproduce on our end.
Why performance varies
Some devices support hardware acceleration for video processing, which means they use dedicated chips (like for decoding or encoding MP4/H.264). When this support isn’t available, the system falls back to software-based processing, which is slower and puts more load on your CPU. On older or lower-powered devices, this can result in sluggish performance, long export times, or even crashes.
Not all MP4 files are equal
MP4 is just a container format, and not all MP4s are built the same. Differences in:
Bitrate
Codec settings
Resolution
Audio format or number of audio tracks
...can all influence how well a file works. A heavily compressed or poorly formatted MP4 might cause issues on one device, but work fine on another. That’s why some videos may work perfectly, while others don’t.
Troubleshooting Tips
If you're running into problems with MP4 videos, here are some things you can try:
Convert the MP4 file
If a specific video won’t export properly, try converting it first using an online tool like cloudconvert.com/mp4-converter or download Handbrake video transcoder. This can help fix codec or formatting issues that may be causing problems.Check GPU usage
On Windows, make sure your PC is set to use the GPU for video processing and export, if supported.Update your drivers
Especially on Windows, ensure your graphics drivers are up to date (download them directly from the NVIDIA, AMD, or Intel website if possible).Switch to Software Encoding
In the export settings, try setting Video Acceleration to "Software" instead of "Hardware".
