Hey everyone i wasn't quite sure where to post this under, im not completely sure if its a hardware issue or a program issue. But when i record a video with anything over 7 frames per second in gtk-recordmydesktop the video playback after the recording move 2x or more the speed it should be. While the voice itself plays in a good pace.


Also, I use the "Encode on the Fly" option, without this option my video is horribly choppy but it works at regular pace. In this sense it may seem like a Video Driver fault, or even maybe my processor can't keep up?
heres my video lshw entry:

Also my audio:

What's the complete program's name ? "Neva manage" ? I can't find it on the repository and on the internet... thanks for helping.

I think he was saying that he "never managed" to get it working with video and sound altogether :lol:

The video is too slow because, during the recording, your computer is too slow to record and compress the requested number of frames per second. When the computer can only manage, say, 5 frames per second but you requested 20, the video will run 4 times too fast.

The solution is to reduce the requested number of frames per second, (in the advanced section of the options), or use 'no compression'.

Works like a charm!:P I had it as "Encode On The Fly" but changed it to 'Zero Compression'. Although it takes a while to encode after recording, at least now it work as it suppose to be.

Thank you very much...:guitar:

I lowered the frame per second to 6, unchecked Zero compression, checked quick subsampling and finally the video is in normal speed and in perfect sync with audio.
Looks like my Intel P6100 is not able to encode my 1366*768 screen on time and was loosing lots of frames.
I did not notice any change to the video quality for what I am doing.
Thanks Tinooz and all...

Any idea on how to fix the video to match the sound. I recorded 10 mins of tutoring and would prefer to fix the video as it already took me 2 hours to get the video perfect(though then I noticed that the video was fastforwarding).

Hi
on the Advanced Menu change the following Setting
Performance\Frame per Second = 10
enable the following option:
1-encode on fly
2-zero compression
3-quick subsampling
4- full shot at every frame

I think that lowering the video quality will reduce the CPU usage by the compression, so it will not skip frames
