I have been having issues with the quality of a GoPro video I have uploaded to YouTube, it’s my first effort so quite possibly not doing it ‘properly’.

The GoPro data files were initially edited on iMovie, then on also Windows Video editor as a comparison. The export from both editors produced very acceptable .mp4 files, both looking rather good when run locally.

However, when uploaded to YouTube, everything goes seemingly to 480p rather than 1080p, but then ‘fixes itself’ at various points by going back up to 1080p, plus one background music track (all music is YT provided tracks) has just disappeared on the uploaded videos altogether.

So a problem with the upload process?

I then discovered that the loss of quality happened at the exact same places 'on the ground' no matter what the edit or length of clip. So, I made a small length video using just one GoPro file and sure enough, the local .mp4 is just fine but the uploaded videos have the failure happening again at that same point in that video too even though that point is now just 10secs into the video rather than 2 minutes!

This suggests to me there is something awry with the original mp4 file out of the camera – but then why do the local mp4 files run 100% ?

Any ideas?

You may be having issues with the variable rate of the video from the GoPro. Video processing can get a bit wonky unless you fix this. Download the free app called Handbrake. Take your GoPro footage you are having a problem with and run it through that. The programme looks very busy but you can ignore 99% of it.

On the video tab set the framerate as same as source.

Choose constant framerate button below this.

Then Start Encode.

One you get used to the handbrake product you will find you can load bunches of GoPro footage and have them all run through automatically in the background while you do something else.

Just choose a different disk location to save your processed files. Now you can use these new files in your video editing and you should no longer have these problems.

Thanks Tev62, will download and give it a try.
