hello

my video footage is MXF, simple:
add track in video. the project is 1920x108025p, my video footage is 1920x108050i

render out in mp4 (fast):
play with vlc like as video is hight speed..this is strange.. or problem from mlt or ffmpeg?
play with ffplay like as video is hight speed..this is strange.. or problem from mlt or ffmpeg?

video MXf vlc is perfect play with normal speed...

instead kdenlive old version 0.9.8 ---update>>> 0.9.10:
render out mp4 high: result perfect speed is normal.

kdenlive 15.12 is instable than 0.9.8 ---update>>> 0.9.10:..for moment..

my jobs use kdenlive 0.9.8 ---update>>> 0.9.10: and not kdenlive 15.12... i will wait to STABLE of 15.12..

i do test for 15.12 for my jobs have many issue.. so i'm stop here..

i hope kdenlive will be stable next version..thank you

hello

few minutes ago i tested to SHOTCUT (mlt) also same olther topic ( i did created topic), so i can repeat here little report:
shotcut is worked perfect to render out mp4, not high speed but speed is normal as perfect.
so shotcut used with ffmpeg old version 2.7.x and not ffmpeg 2.8.x, shotcut is latest version.

see the box of shotcut, there are ffmpeg, ffplay,ffprobe,melt,qmelt

then maybe this is problem ffmpeg 2.8.x for RENDER.. but kdenlive 15.12 cant use with ffmpeg 2.7.x... can does fix it for old ffmpeg for moment?

sorry i-m wrong.. my kdenlive version is 0.9.10..

hello

today, i did add file MXf footage original from canon xf105, you can try it's free file forever:
https://mega.nz/#!vpxUWToJ!cL4a3rtGfznH ... oDuJ3QMVOE

i did post in bug report for add file footage original ok?
https://bugs.kde.org/show_bug.cgi?id=357319

i hope team develops wil can test MXf with kdenlive 15.12 ok?

here MXF footage original, scene object with motion,
link:
https://mega.nz/#!D0ojBJQA!W476CDKWyBbD ... tT20Wdt8oM

please all people can use this MXF FOOTAGE and test with kdenlive for 3 issues, is true problem serious.. ok?

Who knows how long it might be before this issue is looked at.
As a work-around - have you tried using ffmpeg to transcode your source video to a different format?

I note that you have 0.9.10 of kdenlive. Have you tried the latest version of kdenlive? Developers do not except bug reports for old versions of kdenlive.

i did tried convert ffmpeg:
ffmpeg -i XXX.MXF -c copy YYY.MXF
result:
kdenlive 15.12.1 with ffmpeg 2.8.x, video play like as high-speed
kdenlive 0.9.10 with ffmpeg 2.8.x, video play like as high-speed
kdenlive 0.9.10 with ffmpeg 2.7.x, video play like as normal-speed

shotcut 15.12.3 with ffmpeg 2.7.x, video play like as normal-speed
shotcut 16.01.01 with 2.7.x, video play like as normal-speed

blender 2.76 ,video play like as normal-speed (i dont know what is version of ffmpeg..)

ttguy wrote:I note that you have 0.9.10 of kdenlive. Have you tried the latest version of kdenlive? Developers do not except bug reports for old versions of kdenlive.

see before i did wrote..

but you can try with my original footage MXF with your kdnelive latest version?

So you notice that your results strongly indicate a problem with ffmpeg 2.8.x? Why don't you get the recent ffmpeg sources from the ffmpeg git repo and compile them, then run your video files through them, seeing whether the problem persists? If not, bingo, use ffmpeg as suggested above to transcode, then edit and render in Kdenlive using the transcodes files. Otherwise, please inform the ffmpeg developers of this issue. This doesn't appear to be an Kdenlive issue, but please correct me if I'm wrong.

For Ubuntu 15.10, here's the ffmpeg repo, maybe you may try this?

hi

sorry for late. i want to test for confirm, but how i can start to compile from ffmpeg source to my computer (opensuse) for test (for to know/understand what is problem from..)

first i need?
- git ffmpeg? after what i will do compile?

never i do to use compile.. i nned step-step...opensuse 42.1..

hello

what is news for this problem..?
i check report bug nothing news.. this bug is forever?
i need latest version of KDENLIVE, but i cant to use it..because my MXF not works with latest version of kdenlive..

for moment i use old kdenlive (too old) 0.9.10 with ffmpeg 2.7.x

let me news..
thank you

Kdenlive relies on ffmpeg through MLT for processing video files. Of course, you are free to bark up the Kdenlive tree, but don't be surprised if you don't get any feedback.

Ffmpeg 3.0 is out. Check to see if ffmpeg 3.0 solves your MXF issues. You'll need to compile ffmpeg yourself, as I haven't yet seen it available in Ubuntu repositories, only 2.8.x which caused you the MXF regression.

I had to change the arguments to ffmpeg's configure in order to get it working ($INSTALL_PREFIX should be set according to the wiki documentation page for compiling Kdenlive on KDE Frameworks 5):

Code: Select all

./configure --prefix=$INSTALL_PREFIX --progs-suffix=mlt --build-suffix=mlt --enable-gpl --enable-nonfree --enable-shared --enable-libmp3lame --enable-libfaac --enable-libvorbis --enable-pthreads --enable-libxvid --enable-libgsm --enable-libx264 --enable-libtheora --enable-libdc1394 --disable-stripping --enable-avfilter --enable-libschroedinger --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-version3 --enable-libvpx

Then install this locally and make sure that both Kdenlive and MLT use this local ffmpeg instance. You will need to compile both Kdenlive as well as MLT from sources. But this is a small price to pay.

hi

please, i need to help me, how i can compiler for my opensuse 42.1 plasma 5, because i did many times to try how compile kdenlive and ffmpeg and mlt..
i dont understand nothing..really i do never "compile".. so you can help me how will is compiling..please..

i'm ignorant possible...

then my opensuse is 42.1 with kde5 latest updated from yast2.
i wish to try compile to kdenlive git and ffmpeg git and mlt git for to working and testing..
my home path is /home/gokuh5/
for first what i will do first step..?

i want to test ffmpeg 3.0 with kdenlive testing for my office job ok?

I'm using Kubuntu, so I can't help. I left SuSE long ago when their hardware support got incredible worse, yet their ego was big.

hi

i did update to report bug for kdenlive:
https://bugs.kde.org/show_bug.cgi?id=357319

i repeat there information:

kdenlive 15.12.2 with ffmpeg 3.0 with MXF footage is worked! but there is Crash!
