Video Blank

I am trying to edit a video and when I add it to my timeline, the audio works but the video is all black. I also notice that the cavas size gets tiny and when I expand the video box nothing happens. The video works just fine in media player. I have never had this issue when adding video and am not sure how to get it to work. The original recording is from a webinar. Thanks!

Ashelee LaRoche,

 Can you post a screenshot of what you are seeing or a small video ? Is the video something you recorded of your screen or is it from somewhere else ? The reason for asking is if the aspect ratios are not the same it could possibly cause an issue but there are more reasons that I am sure could also cause this kind of issue. Thanks for posting and let us know. Have a great day/night.

Hello, was this ever resolved? I am having a similar problem where an AVI is blank for 20s half way through the project. I can't figure out why suddenly I lose so much video. The AVI plays OK on VLC media player but does have a 2s black out. Why does the 2 sec blackout turn into a 20s blackout? Thanks.

since the AVI plays in VLC, play it while capturing it with Camtasia Recorder; use the resulting trec file in your project; if the AVI has audio, be sure to record system audio

Thanks for the suggestion. The AVI plays in VLC but still has a 2s blackout. We managed to convert to MP4 using handbrake then do some editing to cut out the blackout.  There must be something wrong with the encoding by Camtasia recorder that's causing this. I suspect an AVI artifact that occurs during a screen transition and exacerbated in Camtasia. Any thoughts? Is this a bug?

was the AVI source external to Camtasia [not a Recorder capture]?

if the blank frames are already in the AVI, and it was not a Recorder capture, then I'd assume the AVI was at fault?

perhaps contact free tech support re "is it a bug"

regarding the black frames, in my limited work with old camera footage film converted to MOV, then used Handbreak to make AVI using a cheap converter box, I addressed black frames by patching over with saved frames; allowed me to remove the glitch without disrupting the audio flow
