Frequently asked questions
Should width and height be even numbers?
Yes. The H.264 codec requires even dimensions, so use even numbers for both width and height.
Will this stretch my video if the aspect ratio changes?
Yes, if the new width and height don’t match the original aspect ratio, the video will stretch. Match the ratio to avoid distortion.
What output format do I get?
Always MP4 with H.264 video and AAC audio, regardless of the input format.
