Frequently Asked Questions
Can I merge videos with different resolutions? +
For best results, all videos should have the same resolution, codec, and frame rate. Mismatched settings may cause playback issues or errors in the merged file.
How many videos can I merge at once? +
There is no hard limit on the number of files. However, since processing happens in your browser, very large combined file sizes may run into memory limits.
Can I reorder the videos before merging? +
Yes. Use the up and down arrows next to each file in the list to rearrange them in the order you want before merging.
What output format does the merged video use? +
The output is an MP4 file. The merge uses stream copying, so there is no re-encoding. This keeps the process fast and preserves original quality.
Why did my merge fail or produce glitchy output? +
This usually happens when the input files have different codecs, resolutions, or frame rates. Try converting all videos to the same format first, then merge them.
