Convert CAMPROJ to WMV

If a legacy Windows application or playback device requires Windows Media Video, a Camtasia project must be rendered before it can play there. A CAMPROJ file contains an editable timeline, not a finished video.

What a CAMPROJ file is

.camproj is a project format used by Camtasia Studio. It stores editing instructions, such as clips, cuts, and effects, and may link to source recordings stored elsewhere. Open it in a compatible Camtasia version and restore any missing source media before exporting.

What a WMV file is

WMV is Microsoft’s Windows Media Video format; files with the .wmv extension commonly use the ASF container. WMV can suit older Windows software and devices that specifically require Windows Media files, but it is less universally supported than MP4.

How to export WMV

1. Open the project in a Camtasia version that supports the CAMPROJ file. If media is missing, relink the original files so the timeline renders correctly.
2. In a Camtasia Windows version that offers WMV output, choose File → Produce and Share, select custom production settings, and choose WMV. Set the output dimensions, frame rate, and quality or bitrate, then complete the production wizard and save the .wmv file. Menu names and available formats vary by version; newer releases may not include WMV export.
3. If WMV is unavailable in Camtasia, export the timeline as a local MP4, then transcode that rendered file with FFmpeg:
   ffmpeg -i camtasia-export.mp4 -c:v wmv2 -b:v 4M -c:a wmav2 -b:a 128k output.wmv
   Adjust 4M to the video resolution and required file size. This re-encodes both streams; FFmpeg builds with WMV2 and WMA v2 encoders are required.

CloudConvert can convert a rendered MP4 to WMV, but it cannot render the CAMPROJ timeline. Use an online service only if uploading the video is acceptable; for private footage, use Camtasia or FFmpeg locally.

Quality and compatibility

WMV encoding is lossy, and converting a compressed MP4 to WMV can reduce quality again. Export from the project at the intended resolution and frame rate, and choose a bitrate high enough for the footage; increasing resolution during export does not restore detail. Test the WMV in the destination software or device because support depends on its WMV codec and container compatibility.
