--- Comment #17 from Jesse  ---
Preview render itself, after more tests, is working incredibly!

One thought for solving the zone slider in the timeline: what if the space for
the render preview bars was always visible, instead of only appearing when the
user performs a preview render? So, in other words, it would permanently be a
part of the timeline, directly below the in-out zone slider. That would keep
the slider from becoming smaller and therefore difficult to work with, and
would still give the user a clear visible place for preview renders?

What do you think?

Preview render seems to be working, now. I'll do some more extensive tests, but
the functionality is good enough to close this bug.

Just need to fix the zone tool above the timeline shrinking when there's a
preview render, and this bug will be resolved.

--- Comment #13 from Jean-Baptiste Mardelle  ---
Kdenlive is supposed to detect the best matching profile. It may fail if the
profile uses a codec unsupported by your FFmpeg version. Can you check if that
is the case ?

In a terminal, type:

ffmpeg -formats | grep dnxhd

If the DNxHD codec is supported, you should see a line like that at the end of
the output:

 DE dnxhd   raw DNxHD (SMPTE VC-3)

--- Comment #12 from Jesse  ---
After using preview render on a project I'm working on, a considerably
important suggestion came to mind. I couldn't start the preview rendering, so I
went into Project Settings and changed the preview render profile to "Mjpeg".
Things worked fine after that.

However, this isn't very helpful for new users. Without knowing where to go to
change the settings on the preview render, they'll simply thing the feature
doesn't work... and possibly submit future bugs on an issue that isn't really
"broken". If Mjpeg is more universally functional, might I consider changing it
to that by default? Or finding some way for Kdenlive to automatically detect
which profile would work properly for a project?

Thanks JB. Preview rendering works great! Even on one of my low-end machines
it's running perfectly on a variety of profiles. I dropped the importance of
the bug down to normal.

The only thing now is the in-out zone slider/area selector in the timeline is
still getting vertically squished after a preview render has started. Now, with
the recent changes, that it's become a prominent piece of timeline editing it
seems that its size and visibility is rather important.

Should be fixed now. For HD 1920x1080 projects it will use the DNxHD profiles,
and default to MJPEG if no matching frames size / fps is found. When trying on
an existing project you might need to change the timeline preview profile (in
project settings), MJPEG should work on all profiles

Issue is also present when trying to perform preview render with 720p, 24fps
video. It doesn't look like the preview profile automatically changes to a 720p
one. In fact, it doesn't look like it has a profile at all for it?

24fps now works, thanks JB! However, tested with 23.98fps just for the heck of
it, and it also gets both issues mentioned in the original post.

I think if it can work in 23.98fps, then this bug will be fixed!

Oh fascinating. Setting the Project and preview settings to 1080p at 25fps
makes the preview render work fine. Possibly only an issue with 24fps?

Sorry JB. I wasn't cc'd in the bug, so I didn't get any email updates that you
replied. I'll do a better job at checking in on these.

1. Project profile is 1920x1080p, 24fps.
2. Preview profile is set to "Auto". I tired switching it just now to "DNxHD
1080p 24fps", but it didn't fix. Same thing.
3. Of course! Attaching now.

A few questions: 
* What project profile are you using when you see that error in timeline
preview (I am especially interested in fps for the profile)
* Can you tell me which preview rendering profile is selected (in Project >
Project Settings > Preview Profile
* Can you attach a screenshot showing the timeline ruler with thin selection
zone ?
