Got the console working but cannot switch it to the command mode. So it is not of much use at this point:

Here's a summary of my experience with a Wolverine 8mm scanner purchased in Dec 2018 from B&H, with some tips on how to use the scanner (not included in the brief manual):
Using this scanner eventually gave me better results than
using a video camera to recording an 8mm projection, but I had to work with Wolverine to overcome some shortcomings; this device needs more product development.
The scanner is very sensitive to the write speed of the SD card used. If the SD card’s write speed is not fast enough, the recorded MP4 will likely have periods of what looks like frame jitter and ‘rolling shutter’ effects, caused by the scanner getting behind while waiting for writes to complete (meanwhile, the film advances and it is late taking the photo of a frame, or taking it while the film is moving).
The manual doesn’t talk about this critical dependency, but I eventually learned of it from Wolverine support people. Given the importance of the SD card performance, I believe Wolverine should include a suitable card with the device (but probably doesn’t to keep the price down).
I was able to make the scanner work (barely) using a SanDisk Extreme 32GB SD card rated at Class 10, U3, V30, A1 (many hi-speed cards are larger than 32GB, but 32GB is the maximum accepted by the scanner).
In addition, the card MUST be formatted by the scanner, and one must not delete files from the SD card (just read them), using only format to clear the card. Otherwise recordings will likely have periods of jitter.
It would seem much better if the scanner were to simply run slower, so that it would work with any SD card and never introduce jitter. I would prefer quality over scanning speed.
The scanner seems to do some ‘white balancing’, which sometimes causes colour casts. Unfortunately there is no way to control that.
The tension provided by the take-up reel may also to be a factor. I had best results when using the take-up reel provided with the unit. The (plastic?) clutch on the take-up reel was a source of occasional squeaking sounds, suggesting wear. Wolverine warranties it for 200 scan counts or one year (in USA only). It took me about 70 scan counts to scan about two-dozen 5-inch reels.
To handle a 7-inch reel, I mounted it on a pencil to the left of the scanner and scanned it in two halves.
I found that the frame position within 8mm films shifts. Rather than trying to track that with the scanner (using zoom and frame adjustments), I recommend zooming out a bit such that the field of view always encompasses frames, including wandering. This means you’ll capture frame borders (and even slivers of adjacent frames) but I found that to be acceptable, and if not, more easily handled using post-processing software on a computer.
I believe the scanner’s resolution of 960x720 pixels is more than sufficient to capture the detail in a 8mm frame. I tested this by looking at the spatial frequencies in a recording, using an FFT analysis (ImageJ). Even with a slight zoom, I was satisfied with the resolution provided by this scanner. (Higher resolution and ‘empty magnification’ would just make the output file larger, for no benefit.)
Once a successful process was obtained, scanning went fairly smoothly. The scanner chugs along at 2 frames per second. It’s best to be nearby when it is scanning, so that you’ll notice (usually by a change in sound) if it jams on a splice or whatever.
The device can rewind, but I used an 8mm projector to rewind, which is faster and saves wear on the possibly fragile scanner.
I used the scanner’s USB interface to read MP4 from the SD card (taking care not to delete any files; see above), and processed the files using software on a computer, eg., VirtualDub, Handbrake, After Effects, VLC. I experimented with AviSynth for dust removal and stabilization. Inexplicably, the frame rate setting on the scanner’s MP4 files is set to 30 fps, even though 8mm/Super8 is usually 16 or 18 fps; the file setting can be changed later using computer software.
Wolverine includes a brush to clean dust from the sensor, but I found it ineffective. It is much better to use a can of compressed air, which can blow dust out of the light-well.
Apparently the scanner is made by Winait in Shenzhen. Wolverine is the US distributor; other companies distribute the same product in other regions. The core of the product is apparently a dashcam, which could explain some of the peculiarities described above. It appears that Winait makes gradual improvements; the model I had, purchased in Dec 2018, had a motor-driven take-up wheel.
In summary, I was tempted to return the scanner as unacceptable, but decided that after overcoming problems the scan quality was ‘good enough’. Now I’ve got digital versions of the movies. As film degradation wasn’t as severe as I expected, perhaps in the distant future, if technology is even better, I’ll scan them again. I have a similar thought regarding the digital versions; I think I’ll wait for better, easier to use image processing/restoration software. Meanwhile, I kind of like the 8mm-projection look of visible frame boundaries, dust, and handheld instability.
My thanks to posters in this forum; many posts were quite helpful.
Wolverine, if you're lurking, thanks for your help too, and for trying to serve the low-cost market segment.
