Importing new process won’t stop

Issue: When you import a new process that was initially created on a different PC, the status bar would keep loading and won’t close upon completion.

If you force close ABC Tracker and restart it, you will see the following error:

Resolution

  1. Make sure that there are no spaces in your location path such as the space between “My” and “Documents” in (“C:/My Documents/ABCTracker/”).
  2. Make sure there are no odd characters such as “%, *, #, !, @, =, +, {, }, |”
  3. Make sure that there are no repeated names in the parent folders of the location path (e.g. “… /ABCTracker_1.21.1/ABCTracker/ …”  )
  4. If there are spaces or repeated names in the location path, try reinstalling ABC Tracker to a different location.

What format video does the video need to be?

ABC Tracker uses a MP4 video format for processing videos. However, if your video is a different format, the ABC Tracker Program can internally convert the video using FFMpeg.

Common video formats that we can convert:

  • .mp4 -> Best for ABCT
  • .mpg
  • .avi
  • .mov
  • .qt
  • .asf
  • .avchd
  • .flv
  • .swf
  • .wmv

The program can also convert many other video formats. Check out this link to see what format options are supported: [FFMpeg]

How long does converting take?

Many factors influence the speed of the conversion. Here are a few:

  1. Video length
  2. Original format (some compressions take longer to decode)
  3. The PC

Is there is a loss of resolution when we convert videos internally?

  1. Simple answer: If the video is larger than 1920 x 1080 (or a greater number of pixels than this), then yes – the video will be scaled to such.
  2. To be more specific, we are limited by the number of pixels in the video. The maximum number of pixels is [1920 x 1080 = 2,073,600]. Videos in an unusual width/height ratio will need to have less then roughly 2 million pixels to avoid resolution loss.
  3. Note: There is a slight quality drop with almost any conversion made internally (or any other conversion tool), but we have tried to make the difference virtually unnoticeable.
