FAQ
Can I resize a video to custom dimensions?
Yes, select the 'Custom Dimensions' preset and enter your preferred width and height in pixels.
How do I prevent my video from stretching or distorting?
Keep the 'Maintain Aspect Ratio' option checked to preserve the original proportions, which adds padding if necessary.
What output formats are supported?
You can export your resized video as MP4, WebM, MKV, AVI, or MOV.
What does the 'Copy Video (No Re-encode)' option do?
It copies the video stream directly into a new container format without re-encoding, which is faster but does not change the actual resolution.
Is there a limit on the video file size I can upload?
