No more 'watercolor' look. The real 'flat' picture. Optimized bitrate settings.

A very nice review of Yi cam hacking using autoexec scripts posted at DIYP by John Aldred:Comment

I really want to say: thank you! This makes the Yi much better! Now I'm getting started with Davinci Resolve for color grading.
Another question: Is a video timelapse in 2k with this flat color possible?Comment

I can say for sure that taking photos has problems with YiMAX-PRO (due to some HW limitations). There are no certain issues preventing from shooting a timelapse in video mode.Originally posted by Ultrazauberer View PostComment

Hmm, okay, but there is only 1080p in video timelapse mode and I think the colors are not so flat like it should.
And which problems you are facing with taking pictures? Because suddenly my Yi frozen and won't react. I had to pull out the battery. At this time I was shooting lots of RAWs. I thought the SD card is the problem.
Two questions:
- There is a RAW timelapse script. It shots 7.9 exposures in 8sec intervals. I want to shot at day light with 8 seconds interval too. Can I just set the ISO to 100 and leave the shutter speed on auto? Because I want to shot a day to night timelapse and don't want to overexpose the daytime shots.
- On your XiMAX-PRO script, where should I insert "t ia2 -awb off" for disabling the Auto-WB in video mode? In the main loop?Comment

The trouble occurs when a photo is taken in the same time with script updating its settings.Originally posted by Ultrazauberer View Post
Two answers:
- Yes, 8 sec should be enough to save a RAW file without any problem. But here you have to choose: night or day, under- or overexposure because auto shutter will not go any close to 7.9 sec at any ISO
- You must change 't ia2 -3a 1 1 0 1' to 't ia2 -3a 1 0 0 1' in the main loop and add your "t ia2 -awb off" above it in order to work properly.

This is an example how Xiaomi Yi camera perfoms with 7.9 sec shutter and ISO 3200 in the night.

Thank you for the information. You captured a nice timelapse!
What about video-timelapse mode? If I change to video-timelapse in the Yi Action Cam App the resolutions drops to 1080p and it seems your YiMAX-PRO script isn't working. Maybe there is a video mode for 2K and 5fps or something similar? That would be nice to have a in-camera timelapse video in 2K! :-D
Just for entertainment I attached two snapshots to demonstrate the capabilities of the Yi with your Script! I changed the lens to a 3mm non-fisheye f/3.5 one. I really like this combination.Comment

It's this one: http://www.ebay.com/itm/MOJ-Lens-3mm...0AAOSwnH1WWvTx
I attached a converted RAW image with 100% crops in the frame. I like the lens, but the flaring is quite present. Aiming in direct sun looks cool but if the sun is slightly out of the frame the flaring is ugly. I think a lens hood should help.Comment

Thanks for that, I will try it. Is there a possibility to lock the exposure? For example meter the scene once and keep the exposure settings... This would be useful when filming against the sun. You could aim for a shadow area, turn on the cam and then start recording and point to the right frame.Originally posted by nutsey View PostComment

It doesn't seem to work with software version 1.3.0. The camera keeps beeping when trying to boot. Is there a new version or am I perhaps doing something wrong. Help will be appreciated.
