I've noticed that when using mlv_lite.mo (Raw video v1.1 (MLV Lite)) with FPS override FastTV mode, when recording RAW in 1x crop mode on 5D mark II, it will contain intermittent backward frames.

Watch this https://youtu.be/m1_FBnhzXCs
There are 2 backward frames in this sample sequence, they are marked and should be easy to notice.

Here is the source MLV : https://goo.gl/txLJoN

The sequence will contain more backward frames with slower shutter speed, for example FPS override of 15fps and shutter speed of 1/17s will produce about 20+ backward frames scattered randomly in a 2000 frames sequence.

However, the same settings works correctly with mlv_rec.mo (Raw video v2.0(MLV))

Hopefully this could be fixed. Thanks!

On 5D mark II and USM lens, in Liveview Photo ExpSim with Expo Override set to On, the aperture does not get set correctly. For example a f/32 would only drive the aperture to f/5.6.

Tested on ML nightly 5D2 212 2017-10-03 all the way back to 2016 builds, all showing the same results.

Lens tested :
Canon 70-200mm f2.8 L IS II
Canon 24-105mm f4 L IS
Canon 16-35mm f/2.8 L II
Canon 100mm macro f/2.8 L

Is this a known issue?

I'm trying to get this working for FRSP macro focus stacking, can't untwist the lens because need ML to drive focus.

I've just noticed that while in LV movie mode, the aperture stays fixed at the set Av when taking a still photo, which is great for timelapses to prevent aperture flicker while still being able to do Av keyframe ramping.

However there is a problem, while in movie mode slowest Tv is limited to 1/33 or 1/25 depending on your settings. Using FPS override with a low value limits the fastest possible Tv.

Would it be possible to implement a Tv override while in movie mode that behaves like in photo mode? Thanks!
