IS THERE ANYONE WHO SUCCESSFULLY RENDERED A DVD on TV PLAYABLE PAL VIDEO?

Please, let me know.

After manny attempts I still experience the same kind of jerkiness in my video when played in standalone DVD player on TV (in Kaffeine, Xine or Mplayer it is OK). Generally, when I cut any clip using Avidemux, it's played well in TV, all smooth and in supposed quality. When I edit this clip in Kdenlive, adding some basic subtlitles for example, render it to DVD mpeg or vob, burn it (DVDAuthor or ManDVD and K3B) and play it in DVD player on TV screen it "jerks". Even when the video is paused! It is well visible on edges of objects. Also interlacing is too visible, the comb efect on object edges.

All this makes my video hardly viewable :(

HarryVanDerWolf suggested a possible audio bitrate/codec problem so I tried these export profile options among many others as suggested:

..it is sooo frustrating :(

I tried several both video and audio bitrate options, several audio codecs, checked it back in mplayer, but all the same. No change even in intensity or type of jerkiness. I tried low values, I tried high values, I tried suggested values by Wikipedia (DVD_video article). No change.

This leads me to assumption that this problem is NOT related to video or audio bitrate.

So what is left?

gop_size=15 ??

me_range=63 ?? (google hints that many use 0 as a value here)

video_rc_buffer_size=1835008 mux_packet_size=2048 mux_rate=10080000 ..don't have a clue what is this about

I still use 0.4 version with upgraded mtl 0.2.3 lib, all from SUSE Pacman repo.

Thanks for any idea or help.

Stil lno success, but this findings may be relevant.

Avidemux exported sequence, non-jerking video:

I frame i every 12 frame, so GOP = 12 ?

B frames present, interesting.

I frame i every 15 frame, so GOP = 15 (as was set in render profile)

There are no B frames at all!

This information is interesting:

This information indicates that Avidemux processed clip (cut and copy operation from original stream) is very close to this IBBPBBPBBPBBI.. order. And this works!

Contrary, Kdenlive exported video is IPPPPPPPPIPPPP.. only stuff. No B frames at all. May this be related? Is this MTL or Kdenlive specific? What avlib parameters I can use to achive desired IBP frames combination?

I have to report partial success.

When I reencode video clip rendered in Kdenlive in Avidemux then jittering gone away when playing in standalone DVD player on TV.

Essential is to reencode video (DVD default options) AND SOUND !! (libavcodec, ac3, 384 kbps)

Not an ideal solution but at least some progress :)

So after all harryvanderwolf may be right about the sound cause.

The question is what so bad is done to sound in Kdenlive renderer.

Thank you for reply.

Did you burned a Video DVD, not a data DVD? Suppose DVD Video but just to be sure.

Is your DVD player a simple one (DVD viode only) or DivX or AVI and other formats enabled? I tried only the simple ones.

PC playback of my videos was always OK, no jerking or jittering. The issues described were visible only on standalone DVD - TV player.

Anyway nice to hear that someone did it successfully.

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,

Someone who was new to Linux and Kdenlive asked me via private message how to perform what I mentioned in the message above. Since others might be interested in the same thing, here is the answer I wrote down:

I hope that it might serve others.
