I create several different video clips, when I put them all together and the produce a video the some of them are BLACK - I hear the audio but no video. I've tried WEB, HD with mp4 files as well as custom using AVI and it happens still. Any suggestions?

Hey Brad,

What format are the video clips that you are importing into the timeline? Any additional information would be great! Thanks!

mp4, I created each clip in camtashia and stored them as web "default" and even tried the hd "default" - each clip plays just fine. When I add them to the time line, add transitions and captions it plays fine. Then I do the "Produce and Share" create a video and some come out blank or black - i can hear the audio.

I create mp4 file clips - 30 second short ones - then I try and put them all together and when I view them SOME of the video clips are blank. I hear the audio.

If I view them one at a time they look just fine, its all about putting them back to back on the timeline then producing a video.

I have done about all the things suggested, even

"As a workaround, perhaps try making a project from each separate clip; produce each as AVI or MP4; if those do not render black, then use those in a final project together."

All my clips I make identical and I can view them each separate - but when I put them all together I get - some videos come out BLACK. I've produced now using the same project and it does it to different clips..

I can never get all to work.

I have like 5 MP4 files - all are using quicktime individually. all were rendered using the same output WEB - the default settings. I add each of them to the time line - I can view them all in the studio.

When I render them as WEB - "mp4" the same as the original imports I get failures. I've also rendered to AVI and the same thing happens.

Using Windows 7, Intel Core i7 processor.

This application would be very valuable if I could make it work properly. It is difficult using different applications. creating a bunch of videos and patching them together with another application defeats the usefulness in this app.

Black videos when merging multiple videos still happening.

Hi Logan,

I've uploaded a very simple example I've uploaded - with 5 video files and then produced to create all.mp4 which showes the problem.

Hi Logan,

Any chance this could possibly get resolved today? or a work around where I can use the camtashia studio to create the whole video with callouts, audio, transitions and even PIP... Its would make it so easy to transition vs. doing it in another app and just chaining together what I have.

thanks,
Brad

Hey Brad,

I got all your files, but I wasn't able to recreate your issue. I was able to produce just fine, with everything playing like it should be. Can you send me the camproj file that you are working with?

Thanks.

Send new files with a camproj.... Are you using a windows 7 enterprise machine? 64-bit with an intel processor?

Mine does it every time as you can see by the videos I am sending you - seems like the link you sent with others having the same issue are using windows 7 with 64-bit.

Is this a priority for you? I need to produce the full video soon.

thanks

Hi Logan,

Success! I applied the patch and created a long video with all the clips and pip and it all worked just fine, it is now working as expected.

Thanks for the attention to this!

take care,
