Could you look in to the mlv_dump from experimental. When I convert 60P 3x3 Footage I still have a lot of Vertical Stripes in highlights, even though mlv_dump is doing Vertical Stripe Fix, I am wondering if the code is not fitting for the 60p 3x3 mode or maybe there is an offset which enhances vertical stripes?, Maybe because of the 4 dead vertical rows on the left of the frame (also a bug btw). Especially if I have lens flare or direct sunlight flaring in the lens, then the Vertical Stripes are more visible than anything I've recorded with normal 1920x1080 MLV 3x3. What could be the cause of it?
When I play the footage in mlvrawviewer and turn on Vertical stripe fix in that program, sometimes that will get completely rid of the stripes and other times it will make it worse. Its really weird to work with.
The heavier the grade, the more visible the stripes. To make MLV footage look really good, you have to push footage so much that it crosses that threshold where the stripes become really visible. Temporal Noise reduction will also at times enhance it even more, as the algorithms "think" its important information to keep.
Here is a cropped screenshot from mlvrawviewer with a LUT pushing the image from a log curve, to show you the severity of the stripes.
https://mega.nz/#!8YIHGIJB!hzewH2JBX55vELsy2MPdp3gPSo2mTzlNKe_CQIVqu_o As you can see the, flaring enhances the vertical stripes a lot and in this shot its only part of the image, sometimes the entire image will be engulfed in flare and everything turns to Stripes.. I could not find my shot where I had a full flare, aber its egal, same thing.
Also, it would be really nice if you could add Allow Global Draw - OFF during recording to MLV lite as in the vanilla MLV. Because when I am pressing half shutter to remove overlays, I am getting vastly improved recording times, almost double the time and sometimes continues (depending on scene).
and another bug to report from 60p 3x3, when selecting ISO 100 the Raw Zebras become disabled and the Histogram maxes out at about 90% the way to the right, the channels don't go beyond it, leading the operator to believe that one is well within ETTR range. The non-raw spotmeter also maxes out at 96% (not sure if also at other iso's).
Also a general question, why is it when hitting record button, that the recording starts so "sluggish", like 1-2 secs after, does it need to write information to a buffer or something, is it not something that could be done before hitting record, I mean just by entering the mode and keeping it Armed for recording? Also when recording stops, it takes about 4-6 seconds before I can hit record again, maybe longer.. It is quite counter productive, when one wants to shoot a lot of bursts at times and having to wait these combined almost 10 seconds per clip. Is it something one can expect some improvements on in the future ?

Thank you for your time.
