Overlaying to Go Pro Footage

[olnorth]

Hi, I'm sure this has been asked before, but I've tried to find the answer and I can't.

I've recorded Go Pro footage (4Gig) of a session. I also had lap timer recording data but no video for the same session.

I want to pull the video of the fastest lap and add the Laptimer data to it.

Since the Go Pro footage is 4 gig, I put it into Final Cut Pro, cut it down to the fastest 1 lap, then exported the file.

This file was a 5 gig .MOV file, which I then converted (using handbrake programme) to a .MP4 file which is a more manageable 39MB.

I sent it to my phone via Dropbox and saved it to my phone camera roll.

-------

I go into Laptimer app, select the fastest lap from the lap list, click 'Edit' then 'Add Video' then select the lap from the list of 'camera roll' videos.

I then see the 'Video Sync Setting' scree, but it's just black and my video doesn't appear. I think this is where I would sync the end of the lap which would then allow me to overlap the data. Why am I not able to see the video and select the finish line frame??

Thanks in advance.

Except for low memory situations, there is no need to cut down the video ahead of transferring. Using the sync features mentioned, LapTimer can extract what is needed itself.

The problem you run into is some issue with the video format. 39MB sounds to small anyway. For HD a standard size per minute is 90 and for FullHD 190 MB. So either this is a very short lap or it is over compressed.

For iOS I'd suggest to use a MOV container with the video track using h.264 and audio using AAC encoding.
