Cody and Jeff, Thank you very much for all your time. You were very helpful! I think my two last posts were completetly unnecessary as I found the mistake. I didn't change the settings in excel permanently so every time I saved the file to .csv there were semicollons created instead of commas. I kept it in mind during few first tries but I just forgot while using the final version of .csv file. So I am really sorry for confusion. Now everything is working correctly. You are the best. Thank you very much! Aleksandra

I used 5 meters. It didn't help. Can it refer to any windows settings?

Hello, I would love to say that it is working but unfortunately not. I also tried on different computer just in case something is wrong with mine but it also didn't work. So if you checked the video and .csv file and they are fine, maybe I am using Video Multiplexer in a wrong way or maybe there is something wrong with the version of ArcMap? I have 10.5 and also the FMV add-in is for 10.5. Is there something wrong with my input parameters in Video Multiplexer? Thanks, Aleksandra

Hello, Link: https://drive.google.com/file/d/0ByG4dTI3zYX8LVBmVmlhS2Q1NWM/view?usp=sharing Let me know if the link is not working. I am sending you the video, the original .csv log file, and .csv file prepared to use in video multiplexer. I have completely no more ideas what might be wrong. Thank you very much for help.

Hi, So, I have changed semicolons into commas but the output movie is still the same. I also prepared the new .csv file containing all the metadata (not only with the interval every 1sec) but it didn't change anything. Finally, I changed the elevation values to absolute heights (not a big difference as I am not more than 10m above see level) but it also didn't bring any changes while running Video Multiplexer. As I didn't have values for Sensor Relative Azimuth Angle, Sensor Relative Elevation Angle, Sensor Relative Roll Angle stored in the .log file from drone I just made-up these values in .csv file. May it be the problem? But as I understand it can lead to wrong geolocation of movie, but not to 'not creating movie at all'? Just in case you want to examine .csv file, I am sending the new file with all the records. Thanks, Aleksanda

Hello Cody and Jeff, Thank you for the quick response. Some answers and explanations: 1. The video is in .mp4 format. The raw video plays when I drag it into Video Manager. It has no geolocation but plays with no problems. The movie is 30sec long and the size is 364MB. 2. GP tool runs for about 6sec and the output .mp4 file is empty. 3. To get metadata from Phantom 4 Pro I used .log files stored in the tablet after the flight. They were in .txt format, so I used the http://www.phantomhelp.com/LogViewer/Upload/ to convert them into .csv files. As I only wanted to check if this is going to work I reorganized the file manually in excel to prepare it for use in Multiplexer. 4. I used the Epoch Converter - Unix Timestamp Converter . From the .log file I chose the records with 1s interval, so each row in .csv file has 6 zeros at the end. 5. The time stamp column is saved as the number, but every time I open .csv file again it is converted into scientific notation so I need to do it again and again. Is it correct way? 6. As I decided to use local height system, the first height recorded by Phantom is 0 meters, so when I check the 'Calculate Four Corner Data' as the average ground elevation I type '-10'm. (I found it on one forum that it should be lower that the smallest alltitude). Is it correct? I believe the problem is one of my unresonable assumptions while creating .csv file compatibile with Multiplexer. The file you can find in attachment. Thanks, Aleksandra

Hello everyone, It has been a long time since anyone posted with questions about 'Video Multiplexer'. I hope someone can help me with my issue. I captured some georeferenced videos with the use of Phantom 4 Pro. I have log files from flight and I converted them into .csv files. I 'reorganized' the .csv file in a way described by Jeff in the posts above. The drone log file contains parameters equal to: UNIX Time Stamp, Platform Heading, Platform Pitch, Platform Roll, Sensor Latitude, Sensor Longitude, Sensor Altitude, Horizontal FOV. For Sensor Relative Azimuth, Sensor Relative Elevation and Sensor Relative Roll I assigned values based on my observations in a similar way as Jeff did in example above. I am using Field_Mappind_Template file to connect heading from .csv file to MISB format. I also converted my time stamp to UNIX format and made the 'number' field format in excel. When I run 'Video Multiplexer' the process appears as complete but when I want to open videoor add in to ArcMap I get the message 'The video could not be loaded. Please chceck the file or stream and try again'. I suspect the problem is with my .csv file but I have no more ideas what can be wrong. So maybe someone experienced something similar? Or maybe someone is also using Phantom 4 Pro and have another workaround? Any help would be appreciated. Aleksandra
