HB encode of 720p HD recording motion judders

[starfury_de]

Using a MacBook 13" 2GHz Intel Core 2 Dou I am trying to recode the recordings from my SAT-reciever in a less size consuming format with Handbrake 0.98

After the encoding with any preset of Handbrake I obtain a video which judders at fast motions and camera pans. I tried playback of the video with VLC (2 different versions), mplayer and my Samsung LCD TV with the same behaviour.

The source material is a transport stream containing a x264 video stream and 3 audio stream from which I discard 2 while the encoding process, this is a part of the Mediainfo output:

BTW: Could anybody tell me what "sync: video time didn't advance - dropped X frames ..." mean?

I tried some other video streams of the same source (SAT-reciever) with the same juddering result, wether I try any setting of the framerate (Same as source, 50fps variable or constant, 25fps constant) and with detelecine and deinterlace on and off, nothing matters. I also tried encoding with constant bit rate up to 10.000kbps without any change.

For test purpose I encoded the video with FFMPEG and got a reasonable result without any juddering and soft motions (although a little bit bigger in file size).

I read through the forum and many other interesting source in the web but can't find a solution.

Can anybody point me to the right direction to get a adequate result for my videos with handbrake.

Thanks in advance

I would guess, just by seeing what your source device is, that you need something to reindex your ts files. I don't know of any for OS X.

[HandyMan]

Depends on what you used discard the audio tracks.
I am getting similar audio gap when I cut some ts file with Avidemux.

[mduell]

Cramming down the framerate to a constant 25fps will almost certainly be a problem. Leave it as same as source/variable.

[starfury_de]

A few additional words to the source. As most of the SAT-recievers recording to disk the files are splittet into 2GB parts. I am joining the transport streams with "cat". After this I am cutting the resulting file with avidemux3 (2.6.0) and saving the result with streamcopy in a mpeg.ts to disk. (If I'm not completely wrong, avidemux is re-indexing the files.)

The audio track are discarded only in Handbrake, where I only select the stream I need.

Regarding the framerate I also tried to leave the framerate "Same as source", with the same juddering result, but as mentioned ffmpeg seems to handle the files without any problem in the output.
