Video problem with Tracker Online

2 Posts

Hello,

When I use tracker online to open a .trk file, I have an error message : the video is not found (picture is joined).

I don't not what is the problem with the location of the video.

Then, an other message suggets to convert the video in .mp4
But this one is alerady an mp4 file...

I have no problem when I work with the program loaded on my computer.

I try to use the online version because my students work with a Chromebook.

Thanks for your help !

Tracker Online does not yet load trk files.  Please package the trk data file together with your video in a TRZ file using the Save | Project menu.  

There are many mp4 codecs and Tracker Online only supports browser-compatible codecs.  Please encode your video using H264 codec.  We often use the Cloud Convert online converter or the HandBrake app.

https://handbrake.fr/

Another possibility is to convert your video to an image stack. the TRZ file will be larger, but an image stack will always works because it does not use a codec.

Thanks for your advices.

I do all the steps you describe.

I have converted the video wtih handbrake (into an .mp4 file with codec H264).

I save my work into a .trz file on my computer. But when I want to open this one with tracker online, the download fluctuates between 0 and 10 % et never opens...

Is the video to big for the online version of tracker ?

Thanks for your answer.

Thank you for reporting this bug.  What operating system and hardware are you using?  We can reproduce this bug on an iPad but not on a desktop computer.

A new version of Tracker Online has been released that supports touch devices.  We recommend that users use a 'pencil" rather than a finger with touch devices.
