As you have mentioned yourself, the problem is with your version of MLT. The latest versions of MLT play HD files quite smoothly. To get the latest version (0.8.2), use the following PPA:
https://launchpad.net/~sunab/+archive/kdenlive-release The same PPA also has the latest version of the frei0r effects library which you may also want to update. Decativate the PPA after you have updated MLT. ** Changed in: openshot Status: New => Invalid -- You received this bug notification because you are a member of OpenShot Bugs, which is subscribed to OpenShot Video Editor. https://bugs.launchpad.net/bugs/1066558 Title: .MTS video does not play in Openshot 1.4.3, some errors reported after running in shell Status in OpenShot Video Editor: Invalid Bug description: I like Openshot, I think it has a great design, thanks to Jonathan. But I have never been able to use it, because I have an AVC/HD camera, a complicated video format, even for the proprietary windows software included with the camera. In previous versions I could play inefficiently .MTS files, but in the present version 1.4.3 the screen shows white, and the soun stops every second. (I includded a screenshot attachment). The program crashes frequently. Recently I reinstalled Openshot in this computer: $ uname -a Linux computer 3.0.0-24-generic #40~lucid1-Ubuntu SMP Wed Jul 25 14:03:01 UTC 2012 x86_64 GNU/Linux $ lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit CPU(s): 2 Thread(s) per core: 1 Core(s) per socket: 2 CPU socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 15 Stepping: 6 CPU MHz: 2000.000 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 4096K Here is the output, when launched from bash. $ openshot ------------------------- ERROR 1 ------------------------------ Failed to import 'from openshot import main' Error Message: cannot import name main ---------------------------------------------------------------- -------------------------------- OpenShot (version 1.4.3) -------------------------------- Process no longer exists: 2256.

There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Openshot was installed copying the ppa lines in openshot page, to bash, then sudo apt-get install openshot As far as I know, I did not installed melt alone, It maybe was installed as a dependency when Openshot was installed. It seems that the problem is the melt version, because I can't neither play .MTS videos with $ melt file.MTS Unfortunately Ubuntu freezes the last version of each application in each distribution. It could be the source of the problem, because apt- get does not install the newest melt version. It seems that Jonathan owns a Canon HD camera which records the same video format that has been shown problematic with Openshot and other applications in my system. I hope this helps to improve Openshot.
