Getting to an output file that is larger than the input video can happen in some circumstances, for instance if:
- your input video is already compressed efficiently and cannot be compressed further.
- your input video is encoded using an efficient video codec already (H.264, VP8,...) and cannot be compressed further.
- your input video is encoded with a video codec that is more efficient than the output settings you selected on clipchamp.com. This can be the case if you convert a video into WMV for Windows/Microsoft Office applications, for instance.
- you convert an MP4 video into an ASF or FLV video. In these cases the resulting file will be larger than the input video as ASF/WMV and FLV are less efficient video codecs than MP4/H.264.
- you selected an output resolution that's bigger than your original video's resolution.
One way around this is to reduce the resolution of your video instead of selecting the "Keep" output option or an output resolution that is larger than the resolution of your original video.
Another option is to select the "low" quality output setting.
However depending on the resolution of the input file and the output resolution you select as well as a number of additional factors, the output video file might still not be smaller than the original video.
Another option is to try a different output preset, for instance "Mobile" instead of "Web".
Generally, Clipchamp is able to significantly reduce your input video's file size in the majority of cases but there are some situations where the video processing technology we use behind the scenes is reaching its limits. We're sorry if your input video is one of the few where this occurs.
