Rendered DVD video - picture "jerks" in TV DVD player

I've just burned a slightly longer seq of 4 clips to a disk and it played ok on my tv from a sony desktop player. There is a bit of pixelation on one transition but no jerkiness. I'm a real Linux beginner so I dont know much about the technicalities. I used Brasero to burn the disk.

hi espinosa,

i'm experiencing the same problem.
i have footage from a minidv camcorder which i converted to dvd (on my hardware dvd+tv plays ok).
then i made a kdenlive project with these clips (added titles, etc) and when i exported the project to dvd i got the "jerky" effect
on the hw dvd+tv.
then, i read your posts at sourceforge

http://sourceforge.net/mailarchive/foru ... live-devel

i tried the method you describe, but with partial success (some parts of the clip are still "jerky", but 70% are ok).
the profile i used is:

format=dvd vcodec=mpeg2video acodec=ac3 size=720x576 video_bit_rate=6000000 video_rc_max_rate=8000000 video_rc_min_rate=0
video_rc_buffer_size=1835008 mux_packet_size=2048 mux_rate=10080000 audio_bit_rate=448000 audio_sample_rate=48000 frame_size=720x576
frame_rate=25 gop_size=12 me_range=63 b_frames=2 real_time=0 progressive=1

and in avidemux
for video: i used "DVD" profile (_not_ "DVD lavc") with single-pass quantizer (the bitrate option causes the app to crash if you try to export),
progressive, default matrix, gop 12, and max bitrate 9000
for audio: i used "Copy" (no transcoding needed for audio)
for format: mpeg ps a+v

so, i am wondering if you made any progress, or if ffmpeg or mlt fixed this bug.
this is very important for me because it's the only reason i don't use/recomend kdenlive at work (at work i don't do video editing/mastering, but when i needed
to do a similar simple task, i gave it to someone else ;) kdenlive is not ready for production use).

have you tried v0.5 of kdenlive? if yes, did you see any improvement on this subject?

i am on debian etch with kdenlive 0.4, mlt 0.2.3, avidemux 2.3.0

thanx in advance,

This thread saved me a whole lot of editing work. I edited a family movie with effects and sounds and stuff and everything looked perfect as long as I viewed in Kdenlive. But when I rendered it to a DVD I got the same jerkiness. This is using Kdenlive 0.5 on Mandriva 2008. Before seeing this post I found out that the interlacing is indeed the problem. The standard profile for rendering to MPEG1 gave a result without jerkiness. When I create a custom profile based on that where I change progressive=1 into progressive=0 gives the same kind of jerkiness as when I create the DVD. I don't have to burn it and see it on the TV set, it is already very visible in Kaffeine on my PC.
Anyway, using the profile mentioned above

format=dvd vcodec=mpeg2video acodec=ac3 size=720x576 video_bit_rate=6000000 video_rc_max_rate=8000000 video_rc_min_rate=0
video_rc_buffer_size=1835008 mux_packet_size=2048 mux_rate=10080000 audio_bit_rate=448000 audio_sample_rate=48000 frame_size=720x576
frame_rate=25 gop_size=12 me_range=63 b_frames=2 real_time=0 progressive=1

, the video rendered completely OK without the jerkiness.
I found out that there is a setting in my camcorder that is called progressive. The manual says that enabling the progressive mode leads to better quality of photos. Doesn't say anything else about it. Since I only very rarely take photos with my camcorder, I disabled the progressive mode. Hope that I got rid of that problem know.

Ciao,

to sitor:

I have no luck with recommended settings - still getting jerking vob or mpg file.
My DVD-player does not see any timecode on this file - time counting always hangs at 0:01
If I create a DVD then videos I rendered with Kino or Mainactor play perfectly but Kdenlive rendered videos start jerking after 10-15 sec.
Any suggestions from developers?
