FAQ
How it works?
By using 2022cutting edged AI model to lossless enlarge video, enhance video, AI interpolation make video vivid while supporting b&w video colorization and smooth slow motion
What file type are supported?
Video supports mp4/mov/m4v/mkv/avi, picture supports jpg/png/bmp/webp/gif, and zip file.
How long does it take to process?
The progress bar does not represent the actual progress, the real time required depends on the number of frames of your file and the task settings, AI interpolation will double the number of frames and double the time.
What about privacy? What happens to my uploaded files and result files?
Your uploaded files and results files will be automatically deleted within a week.
Will GPU points be deducted for processing failures?
No, the GPU points deducted will be refunded after deleting the failed task.
Why the video have a jelly effect after the AI interpolation?
There are two kinds of scenarios that will cause jelly effect, lens transitions and motion blur, AI will calculate the frames between these two scenarios, and the final high fps will show jelly effect. bigmp4 will increase the judgment of lens transitions in the future, the current solution is manually crop the video and then use bigmp4 to interpolation or reduce the multiplier of AI interpolation.
Why charge?
In order to maintain high GPU server expenses, we offer a fee-based service. When you purchase the service, your tasks will be prioritized and the size of uploaded files will be less restricted.
Are bigmp4 web demo videos processed manually?
No, the web demo video is all processed automatically by bigmp4 AI and then we crop it to the right size for the web page
