convert openshot/kdenlive to plain melt scripts

Hi:

Since openshot/kdenlive/flowblade/shotgun(latter crashes as soon as
one imports a file in my case) are all based on mltframework, is there
a way to compose something visually in those gui and import the
.osv/.kdenlive etc. to a simple command line executables that can be
used by melt?

That would be great! If something like that already exists, please
give me a pointer. Thanks in advance.

Newbie to mlt, Need some help

Hi:

Newbie here. So bear with me. Requesting the mailing list because I
could not find any documentation what I am trying to achieve
(particularly chroma/luma keyeing, trapezoid formation and others.

§1. What is a command line for a chroma key with melt (which is
possible in openshot with chroma key plugin). I found something as of
below online, but does not seem to work.

melt https://archive.org/download/IMB_SF_R35_C8/IMB_SF_R35_C8_512kb.mp4 in=400 \
    -track https://archive.org/download/IMB_SF_R19_C9/IMB_SF_R19_C9_512kb.mp4
in=450 \
    -filter chroma key=0x00ff0000 variance=0.45 \
    -transition composite

§2. How to replace a known background (video or image) from the
foregrond video with melt?

§3 How to create a trapezoid of video with melt which can be achieved
using filter, Distort >> Corners in kdenlive?

§4. What is the command for text transitions (like scrolling text or
periodic scrolling text) in melt?

I am very curious with the command line stuff. Any help appreciated! Thanks!

With warm regards,
/zenny

Luma key functionality?

Hi,

Just got mail from Flowblade user asking for luma key functionality.
After looking at freior and mlt source it seems to me that we don't
have anything useful.

If indeed there is nothing, I can hack something together with params
"threshold", "slope" and "invert".

Is there some mlt filter that writes to alpha channel that can be used
as an template for making a lumakey filter?

Janne

Shotcut text

Hi,

I've used Shotcut to render timecode with the text filter on a 59.94fps 
video.
It works fine, but i've noticed a small bug after 1001 frames.
It displays 16:58 then 17:59 then 17:00 and so on each second.
This happens on both preview and encoded file.
