Master Video Invalid Error when changing video

Hi,

I just did a couple Auto-X and Harry's seemed to work really well. I was using the iPhone for the main video and also used a GoPro as a multicam. My intent was to use the GoPro as the master video.

After the event was over, i converted the gopro files and got them on the iPhone. I've gone into those Auto-X runs and added the GoPro video as a second video and it works totally fine for Picture in Picture, however when i try to move that video up to master and then ask for overlay, it says the video is an invalid master. I tried deleting all videos and adding back just the GoPro as master and that did not work. SInce these are Auto-X there is is no lap before or after. I did not add any metadata to the file, i just did the relink button and selected the video.

What do you think is the issue and how should i resolve it?

Regards,
Jeff

Can you please send a snapshot of the error message (there are actually several places it can be displayed in).

THanks Harry. Here are the files to see if that helps. This particular one shows one where i tried to use the go pro video as master and the iPhone video as PiP. However, I had the same issue when it was just the gopro video.

Does the video have an audio track? Actually it is strange you do not get a duration in video details and get invalid states not only for the master, but for the reference and PiP too... Have you tested if it is possible to play the video?

Yes, the video has an audio track and it plays correctly when clicked on. I converted it via handbrake and the file size is pretty small as well.

What program and format did you use to edit and convert the GoPro video? HLT is somewhat picky about that for master video.

Also thinking that might be issue. i used Handbrake and picked something apple but maybe the container matters. let me try out some different formats and see. what do you recommend?

For iOS, H.264 encoding and a .mov / Quicktime container.

I got it to actually work with a different setting in Handbrake but it is still doing it as an mp4 not a mov. I don't know a good free mov converter for the PC. Do you? I'll try this again and see if it still works. if so, i'll keep doing this but I am really not sure what has changed.

on a separate note, for AutoX, it seems like the sync is slightly off and i play with the video end of lap option but I am not sure if that is what really helps me get the proper sync. are there any tips you have on how to best do this?

In case it is not possible to specify .mov in Handbrake (which would be strange from my PoV), you may try the underlying free command line tool ffmpeg:

ffmpeg -i GOPRxxxx.MP4 video.mov
