Hello

I've got a problem with my clips from a Sanyo FH1 (1080p60 - 1920x1080 60000/1001).
In the beginning of every clip the picture gets gray and it looks like a broken codec, I have 3 very short and bad sample clips plus one exported movie. It actually doesn't matter what codec I use or what picture size, it's always the same:

http://www.bentheten.com/samples/SANY0217.MP4
http://www.bentheten.com/samples/SANY0218.MP4
http://www.bentheten.com/samples/exportfile.mp4

OS: Ubuntu 9.04
Kdenlive and ffmpeg: launchpad sunab repository

Is this a codec problem from ffmpeg or is there anything I can change in Kdenlive to get around this problem?


Thanks a lot.
Ben

Ubuntu ships broken and old versions of Kdenlive.
Try Kdenlive 0.7.5 and mlt 0.4.4.
Does it make a difference?

Thanks for your reply

as I wrote in my previous posting I use the sunab repository therefore I use
ii kdenlive 0.7.5-0ubuntu0 a non-linear video editor
ii melt 0.4.4-0ubuntu0 command line media player and video editor

Cheers

MLT relies on FFmpeg codecs. What version of FFmpeg is installed?
Could you try ffplay yourfile.mp4 and melt jourfile.mp4 and see if the problem arizes from FFmpeg or MLT.

ffmpeg is version 0.5-svn+3:0.svn20090303-1ubuntu6+patch~ppa3 and it's built on Jul 11 2009 with some patches (else not even the audio works).

hmm ffplay and melt have this error .. sad

the following error shows up on both applications
---
[h264 @ 0x97deca0]B picture before any references, skipping
[h264 @ 0x97deca0]decode_slice_header error
[h264 @ 0x97deca0]no frame!

Thanks
Ben

Today's version of FFmpeg does not work either in ffplay.

I just recognized that every other format of the camera plays absoF******lutely perfect in ffplay except for the one I use.

720p30 is ok
1080p30 is ok
1080i60 is ok
1080p60 is BROKEN

have you tried converting to AVI? its what i have founnd to work in desasters... never figured out why.

2 other questions.
why you shooting at that resolution? in other words whats your intentions?
Why you transcodeing before editing? often you cut out problematic bits any way?

ps never used one of those cameras before
pss ntsc stands for Never The Same Colour - so one could argue its expected behaviour :)

He is using HD resolutions. There is no such thing as HD NTSC. HD for most NTSC regions is called ATSC - N(ever) -> A(lways) ;-)

60i or 59.97 is a ntsc format, 50i is a pal format. this is done for roll back on compatibility issues.
atsc is a standard that includes NTSC. Most of the rest of the world works on different standard to the usa which, although there is wisdom in why, has held the TV industry back.

when scanning 24fram film, you scan ntsc formats at 23.98 and then use a 2:3 pulldown to make NTSC or similar for 60i
PAL is scanned at 25 frames with a delay or 2:2 pull down.

why i asked was unless you going to blue ray shoot in NTSC DVD support it.

so i conclude (N) never! :)
