In the old version I was able to open multiple video simultaneously. I opened even 15 videos at time and worked very fast from one to another. In the new version I have to open one video at a time, waiting that the video is opened in Tracker and than opening another and so on. This is time consuming compared to the old version. maybe it can be fixed with a new update?

Hi,

In my experience whilst using Tracker (Version 5.1.5) I have found that I am able to drag and drop MOV files in, but the exact same video in MP4 format will not work and comes up with the error message I attached as a screenshot.
For people who are facing the same problem I use the free app 'Any video converter lite' to convert my files (this is on a Mac).

My questions are:

1) Do MP4 files just not work in tracker? Or am I missing something that will allow me to skip the conversion step. I ask this because the videos I shoot are at 100 frames per second. Converting them reduces them to 30 frames per second, which is an issue.

2) Is there a max file size for tracker?
I ask this because I have a video split into 4 seperate MOV files (~1GB each) that all upload okay when done individually. However, I would obviously prefer to analyse this video as one large video, however when I combine the files (file size ~4GB), and then try to upload it into tracker I then get the same error message as the one I have attached. The only difference I can see between the individual videos and the combined video is the larger file size.

Thanks!
Jack

I recorded a video on my iPhone and then tried to upload to tracker but every time it just says that tracker could not upload the video. I have tried multiple times to redo the video, delete tracker and re download the program and nothing works. I will post below the image that keeps popping up every time I try to upload the video. Please help
