Hi,


I have Problems working with MTS files from my Panasonic HD 220. 1980*1028p 50fps

I can't skip: The monitor shows always the first frames.
I cut the file, but the second part shows the content of the first.

No Problems with mpg4 . m4v, etc

Any idea?

ubuntu 14.10, (installed a few days ago9
kdenlive 0.9. 10 (via ppa)


Thanks

Does avplay / ffplay seek in the file properly ? If not, then you know where to look for an upgrade...

Where / how can I check?


B

avplay [your file]
if you are on debian/ubuntu/derivatives, or else
ffplay [your file]
then right/left arrows...

The MTS-Files are fine with VLC / SMPlayer!

They don't work in openshot, too.


What now???

But what about ffplay ? We want to know if they work with ffplay because that is the software that kdnelive is based on. So if they do not play on it then you might need to upgrade your ffmpeg/avconv

I haven't encountered this particular problem, however sometimes imported mts files are only as long as imported image files, when they are actually much longer. This is almost always the case with the first file from a Canon VIXIA HFM40

To fix this on Linux, I use this in the command line:

Code: Select all

ffmpeg -i in.mts -c copy fix.mts

I created a scriptfile containing the following in an executable file called mtsfix in ~/.local/bin/ :

Code: Select all

ffmpeg -i "$1" -c copy "${1%.MTS}-fix.mts"

Importing the output file gives the correct length in kdenlive:


I have a problem that sounds somewhat similar to yours with videos recorded on my iShare S200 (I do not recommend that camera!): The video in some files starts from the starts at some point without warning. A problem that's hard to spot because if you seek into the affected area, the problem doesn't occur. You have to play back the frame which actually causes the defect.

ffmpeg wasn't able to fix this, but avidemuxer was able to:

Code: Select all

avidemux2_cli --load in.avi --no-audio --save out.avi

or as a script (~/.local/bin/avidemuxfix):

Code: Select all

avidemux2_cli --load "$1" --no-audio --save "$1-fix.avi"

Please note that I have not tested the latter with .mts files, only .avi

Let us know if any of these help!

Since this topic is about MTS problems. I'm encountering something weird. Here are two videos (on youtube) that I rendered same system;
1. https://www.youtube.com/watch?v=jmiKvy4OMTQ
2. https://www.youtube.com/watch?v=LRcNNMAy_no

The first plays fine, and the second has issues. I have no idea why one video has issues and the other doesn't.
Any suggestions would be helpful

OS = Kubuntu 14.04 64bit with FFmpeg

I have checked the second one and didn't see any problem??
Anyway , what is the format you used to upload your video?

It's bizarre . I use the mp4 = mp4-video+mp3-audio
It appears to be a problem with the multi-threading option. Fine on 2 (MTS) & up 6 concurrent threads (720p)
