IDIS Clip Player – Warning!

A word of warning when confronted with footage inside the IDIS Clip Player.

At first glance, receiving footage inside the IDIS Clip Player appears to make things easy. It all comes down to what the footage is, or more accurately, how important it is.  I suppose then at this point it is worth pointing out that this dilemma appears to be more common.

It is very easy, and far less expensive, to purchase a video surveillance system designed for residential and small business use and then put it to work in a location that should have a much higher level of quality and resilience. Having a low frame rate, low resolution and modified format may not cause too much of a problem in a minor installation but, having those somewhere important could cause a real issue. Link these issues with dropping frames on export and then the Clip Player becomes more of a hindrance than a help!

Dropping frames is the warning here.

Wrapping the video up inside a player executable is quite common and I have mentioned before that in some circumstances, it is possible to separate the two.

The start of the data contains the player, with the footage following on.

I have attempted a number of carving options but (at time of writing), have not been able to carve camera specific footage and get it playing outside of the Clip Player. From visual analysis of the frames, there are movement artefacts being left behind along with blocking that suggests a modified mpeg.

At the bottom are various control and option buttons. The one to the left of the floppy disk icon brings up a menu with options to change size of window, correct aspect ratio etc. Also here, you will find an option to see the frame information.

Info

At least there are options to save the images at the original recording size…… but its the video saving that has interested me here.

save-video

By clicking the save icon and then selecting ‘Save as Video’, the option to export a video clip appears. I won’t go into all the details but the purpose of this post is to highlight that during a number of tests whilst using FFdshow and Uncompressed RGB, Cinepac, and x264 – the resulting videos had the same frame counts BUT had different duplicates and, most importantly, had dropped images that were clearly present in the original.

So, be careful when using this function. Your video export may not be exactly what it should be and may result in images being missed that were in the original.

  1. Hi,
    Were you able to figure out what format type (H264/H263) the video frame was ?
    I’m dealing with same issue & i have tried to extract these frames but no other player
    has been able to identify frame header.

    thanks

    • Yes, most are raw H264 and the video data can be accessed by trimming the player and exe data from the raw hex. Accessing the video streams is easy when its only one – having multiple streams is a lot harder as the h264 for each stream is muxed together.

      • Thanks for the reply. The frame starts with 0x83 which does not look like a NAL unit header. Is this some kind of modified H264 ?? Is there something else that needs to be done to make it work?? thanks again man.

      • mmm… I have just gone through 3 examples and all are H264. Near the 00 00 01 67, there is the word ODIN in ASCI Txt..do you have this? Perhaps we should take this off the comments and continue via mail if needed – david (at) forensicvideo.training
