GoPro video files have slight pops in between then on Vegas timeline

Liberty610 wrote on 1/20/2021, 4:47 PM

Hi all,

I just got a go pro hero 9 black camera. I recorded a good 15 to 20 straight minuets with it for a test. What I found is, the GoPro automatically creates separate files of the video after the file gets to a certain size. This particular test I did, it would create a new video file after every 5 minuets and 20 seconds of recording. When i put these files in VLC media player and play them back to back, it's a seamless transition. you can't tell they are separate files.

For the most part, this is the same when the files are playing back on the Vegas time line, but there is slight 'pop' or 'audio glitch' when it makes the transition from one file to the next. I tried adding slight audio fades on the audio to prevent this from happening, but it didn't work. You can tell that these where 2 separate files that are are transitioning well from one to the other. I even tried cross fading them one frame to see if that would help, but it's still noticeable.

Any ideas how I can fix this? Thanks.

Deselect this option

and remind that Vegas Pro is not a player, but an editor

Use DEVICE EXPLORER to import your files. It should reconnect the files seamlessly.

Thanks. I will give this a try. I know as an editor it doesn't behave like a player, but when i rendered these clips into a new file, the pop was present in the rendered clip as well.

The current files I have on my time line are not on the go pro itself. They are already on my hard drive.

I have done it with a sd card reader, but I don't think you can use Device Explorer from a hardddrive. But there are commands that will connect. Hopefully someone more familiar with that method will chime in.

I just recorded another new clip, and when I have the GoPro connected to my PC, Vegas doesn't see it in the Device Explorer window. I copied the files from the GoPro to my drive, and again, where the Go Pro made the split of the files, there is an audio pop/splt second mute.

From memory something like this works. Should work of your hard drive. Old fashioned DOS

copy /b clip1.mp4+clip2.mp4+clip3.mp4+clip4.mp4 combined.mp4

Edit:

Your basic file is large. GoPro recording breaks the file into about 4.3Gb chunks. The recording time of each clip will determine its size.Gopro recording also creates sequentialy numbered files. The clip segments need to re assembled.

clip1.MP4 is the first file in sequence (4.3Gb), clip4.mp4 is the last file in sequence and will be less than 4.3Gb.

Your clip sequence may not comprise 4 clips. clip 1 will be first clip that is 4.3Gb, clip (1+n) will be the first clip that is not 4.3Gb.

Does the GoPro site offer any guidance? It is a common problem with SD cards. The file system dictates how large files are handled. A little reading will help.

Then there is an easy answer. Make sure that no clip is longer than 5 minutes give or take a few seconds. That way you will not have to consider joining the files correctly and the audio glitch is gone.

My initial reply to was before your edit. I am aware of why the files are split. It's the way to GoPro formats to the SD card. All files have to been under 4gigs. As annoying as it is that this is how it HAS to be done without any options to change it in the preferences, I am aware why it is done.

As far as the 'a little reading will help' comment goes, I already went to the Go Pro site and looked over all that that material already prior to posting this. I also researched this issue on several other websites and forums prior to this as well, and was told 'it was be a Vegas issue'. Hence why I came here hoping there might be a Vegas setting I was unaware about that would help. However, the more digging I did, the more I found the issue occurs with other applications, including Mac users on other editing software.

I also found this very issue on another forum here at the Vegas site, and chimed in on that. I will be trying a couple suggestions there as well.

I'll take this as an attempt of being funny I suppose. But truth be told, this option is not possible. My main reason for purchasing the GoPro was to have a small camera I could have setup stationary in a small space where I am currently doing music production with a partner of mine, and there is no room for my NX-100 on a tripod.

Did you try
-- to connect your GoPro through USB to your hardware and pu it on
-- goto File/Import/Media
-- choose the GoPro on your computer and Import the available files with the same file numbers
-- when they are of the same take they will be stiched together

@Liberty610 This seems to be an unavoidable consequence of the file split. The first audio sample of a file is not at the same level as the last audio sample of the previous file. This creates a jump in the audio which ends-up as a pop to you ears. I have this all the time with my dashcam footage which creates 60s files.

I attenuate the problem using a de-click filter at the track level. I personally use Izotope RX8 Elements De-Click vst, very efficient. Available currently at the ridiculous price of 20$ instead of 130$ https://www.izotope.com/en/shop/rx-8-elements.html.

In the past when I was using Vegas 14, I had Express Audio Restoration which had a de-click module. You can use any other de-click VST of your choice.

Yup. When I tried to select the files, I got an error message that said "Cannot open multiple items from this location. Try selecting a single item instead."

Doesn't GoPro have an APP to transfer and connect files? Can you format the GoPro memory card NTFS or something that takes larger files?

I am not sure about the app. But I did think about formatting to NTFS via windows and then trying it, but I have heard people trying this and having corrupted files because of it.

Ok , than I cannot help you.
My Files of the GOPro Hero 7 with the same filenumbers can be stitched together to 1 file because the fileformat of the card in that GOPro does not allow files to go bigger than 4GB while on my used hardware I can go to a file size that is much bigger.

Another thing to try is enabling Legacy AVC or HEVC decoding depending upon what type of recording you are doing. The so4compoundplug.dll has had a checkered history of properly decoding GoPro files, especially maintaining audio sync.

I don't have any issues with any other clips from files that ceom from my Sony NX100, my Galaxy phone, or my Sony AX100. These of course don't split files like the GoPro, but as far as the snaping goes, there have never been any other issues.

I will give this a look at. Thanks for the info.

You are correct -- device explorer does not see the .MP4 files on the gopro as importable mergeable files. I've had to deal with this for years :(

Like you, there are audio drops between the clips saved by the camera, which stinks if you actually want to use that audio.

From memory, I believe the command-prompt merging of the files does *not* work with .mp4 files as there will still be those audio issues because of how the frames are stored.

I use FFMPEG to merge my GoPro and Osmo Action files. If I just use the pure merge which does zero encoding, it's stupid-fast but also does not produce the result I wanted.

Here's the batch file I use.

..and a short readme-type file describing how to use:
