|Summary||0002361: Wrong start point for video clips in AVCHDlite format|
|Description||Since I've upgraded to Oneiric which ships kdenlive 0.8, the following weird issue appears:|
I have a project with some AVCHDlite clips from a Panasonic Lumix G2. When I set an In and Out Point then and put them in the timeline by pressing the V key, or when I put a clip in the timeline and then cut something at the beginning, the video jumps in at the wrong point (sometimes 10-15 seconds before the In Point - this usually results in short clips just playing from the beginning -, sometimes several seconds later). I cannot determine what difference there is between the point it should be and the one it is, it seems to be pretty random. Audio is cut correctly, though, so the result is totally async.
I can already see this when I preview the project in kdenlive and it stays with rendering. I created a new project with proxied clips. Preview is fine there, rendering gives the same problem.
So might this be an issue with MLT and AVCHD source clips, perhaps searching within videos with this format is buggy. I tried it with .mov source clips from another camera and it works flawlessly. I also transcoded some of my clips to mp4 with ffmpeg and it worked as well. So I could transcode all my clips before using them in kdenlive, but that's not actually the way to go. :)
I've also tried deinstalling kdenlive and all dependent libraries, then adding the kdenlive-svn PPA, then installing the most recent version (kdenlive 0.8.1 with MLT 0.7.5), nothing changed about this.
|Steps To Reproduce||Put an AVCHDlite clip in the timeline, cut something off the beginning, then play the project in kdenlive, melt, or render it to any format.|
|Tags||No tags attached.|
|Build/Install Method||3rd party package|
|Updated to 0.8.2 from sunab/kdenlive-svn ppa, still having this issue.|
I have similar issue without even cutting or clipping anything. In review and rendered result it jumps a few seconds off the video from the beginning.
But i found a workaround:
Put the cue pointer (or what is it called?) on the timeline just before the MTS clip. Then by cursor right -key, go frame by frame (do not press and hold) through the beginning of the clip. Just over the point it tends to jump to. After that they render ok.
