Hi everybody,

first, thank you for this nice and fine piece of software. Since 0.7.4 I prefer kdenlive instead of using cinelerra.

I have 0.7.6. installed and the latest versions of ffmpeg, mlt (not the SVN versions but the current major and minor number releases). I'm using a Canon FS100 SD camera and transcode the native .mod files to DV before editing, keeping the interlaced format.

When I render to DVD PAL wide with kdenlive DVD preset, the camera moves look very jerky on the screen. I encountered the same problem with cinelerra and figured out that I have to change the field order. This is the part from the ffmpeg command that works correctly with nice fluid camera moves on the TV screen:

ffmpeg ... -flags +ilme+ildct -top 1/0 ...

Now I have set up a new rendering profile in kdenlive by adding the ffmpeg-part to the default DVD PAL wide preset, keeping scanning on "automatic":
f=dvd ilme=1 ildct=1 top=0 vcodec=mpeg2video acodec=ac3 b=5000k maxrate=8000k minrate=0 bufsize=1835008 mux_packet_s=2048 mux_rate=10080000 ab=192k ar=48000 s=720x576 g=15 me_range=63 trellis=1 profile=dv_pal_wide pass=2

It does not work. I tried "flags=+ilme+ildct top=1/0" and "flags=+ilme+ildct top=1", "top=0" and other alternatives. I messed up 10 DVDs tonight. Setting scanning to "force interleaved" does not help either.

Does anybody know how to pass the ffmpeg settings correctly to mlt? The rule to change ffmpeg commands from "-command value" to "command=value" does not seem to work. Or maybe my commands are in the wrong order?

Thanks in advance for your help...

Cheers,
Achim

Currently, there is no way to override a field order incorrectly detected by the ffmpeg libs. I will work on this for the next release.

Hi Dan,

thank you for your reply - saves my time, no more trying - and also thank you for taking care about the field order.

same problem here. too stupid that in PAL the field order is changed.
did you find a way to change from bff to tff ?

it would help a lot.

thx

Where does it say a PAL DVD must be top field first? That seems odd since field order is a flag in a MPEG-2 Program Stream.
