Dashcameras participated in this side by side test were using firmware you see below.
NB! By the time you are reading this thread and watching video used here, developers of those dashcameras may have released a new improved firmwares.
Please refer to each developer sub-forum or website in order to see newer firmware release and their performance.


Top: Dimika v1.3
Bottom: Mobius v1.13


I have synchronized Dimika and Mobius videos from the time-point of 1 min 10sec ( please check that time-point and you see brake light of both cars are synchronized ).
Because of Dimika unusual overlap and variable frame rate, by the end of 12min video clip, there is a synchronization difference about 3 sec between Dimika and Mobius.

The biggest issue in Dimika is variable frame rate and "unusual" video clips overlap.
When I am making final cut ( putting together ) many different video clips from one source, I am using a Registrator Viewer, - this is the best and quickest software out there to "glue" together multiple video clips from one dashcamera.
Till now Registrator Viewer was able to cope with ALL dashcam videos that had fixed frame-rate and had "common" 1 sec ( or 0 sec ) overlap option.

Due to Dimika has "unusual" overlap and variable frame-rate video recording, - Registrator Viewer can not cope with "gluing" together correctly multiple Dimika video clips the way they would correspond and could be used to synchronize with other dashcameras video clips.

The only way to synchronize Dimika video clips with other dashcameras video clips is via pain-stake manual process, which takes me about 3-4 hours using AVS Video Editor just to correctly synchronize 15 min clip of Dimika vs other clips. I have to go almost trough every frame, to cut "unwanted" ones in order to keep up with synchronization, and so on. This is not any easy job and for sure not practical !

Also there is an issue with Dimika audio-codecs. When editing videos in Registrator Viewer and AVS Video editor, they do not support audio codec that Dimika uses, or because of variable frame-rate and different audio codec specifications ( see below ), - there is an issue with audio output after video is edited ( watch Dimika individual youtube video ). Yes, you can play individual video files on Registrator Viewer, but as soon as you try to "glue" few Dimika video clips, - then result for audio is high-pitch noise.

NB!
I want to remind: those Dimika audio-video issues exist with firmwares which is mentioned in review.
Please follow Dimika sub-forum on DCT or their website for new firmware releases, where there might be already an updated which solves those issues.

Also strange fact is that Dimika individual video file real total length of 12min 54sec uploaded to YouTube, it shows 51min 40sec. This is due to YouTube does not recognize correctly Dimika videos after they were "glued" in Registrator Viewer.
