Question / Help Problem with Camtasia 8 and OBS

[Fifinas]

Good morning.

Yesterday I tried to record some videos with OBS, everything went OK, but when I tried to input it into Camtasia 8 it said that it is audio, but it was video. I don´t know why it happened, I think it´s something in my OBS option, because anyother mp4 files I can input to camtasia without any problem. Can you post me please your options or what is happening with OBS?

Sorry for my English, I am from Czech republic

You need to activate "Use CFR" in the advanced settings of OBS. And camtasia might need a codec pack installed that supports mp4 files. We recently had a thread where someone had problems with camtasia as well, but with the audio part.
We noticed that Camtasia seems to have certain problems with modern mp4 files, the software really could use an update, but you should get it working anyway.

I am using CFR and Camtasia works well with MP4. It produces videos in mp4 and when i tried to input other mp4 video, that i downloaded from youtube, it worked. So I don´t know.

Hmm, thats strange, I used the test version of Camtasia back then and it had no problems reading OBS mp4 files, I found the thread, it was actually a video problem: https://obsproject.com/forum/thread...-when-editing-with-camtasia.10199/#post-78133

You could try the ffmpeg commandline I explain in the last reply.

Can you explain me what the ffmpeg ist? I haven´t heard about it. And what does it do?

Camtasia doesn't support 64bit MP4s apparently, which we use because our files get really big. Get a copy of ffmpeg, then use the following command in a command prompt:

ffmpeg -i [obs file].mp4 -acodec copy -vcodec copy [new name].mp4

It will create a 32bit mp4 if your mp4 is within a certain file size. OBS unfortunately currently cannot really just switch between 32bit and 64bit because of the way mp4 files work.

So I have to download ffmpeg and then write to the command line: ffmpeg -i [obs file].mp4 -acodec copy -vcodec copy [new name].mp4

And the obs file is name of video? Am I right? Do I need to run ffmpeg? I know, I have stupid questions, but I haven´t heard of ffmpeg never before. And I don´t know, why they put the ffmpeg in 7z. Do you have some download links to download ffmpeg in any other format? I don´t have 7z program.

So I tried it and it said: No such file or directory. I used that command in the command prompt: ffmpeg -i Tanky.mp -acodec copy -vcodec copy Test.mp4. Then I tried to put there a directory: ffmpeg -i D\Games\WarThunder\Videa\Tanky.mp4 -acodec copy -vcodec copy D\Games\WarThunder\Videa\Test.mp4. And it wasn´t working. So I don´t know what I am doing wrong.

it needs to be D:\, not D\

Ohh, stupid mistake, thank you very much, it´s working.
