Question / Help Streaming and recording on a file Issue

[Jota4]

Hi, im a streamer of twitch and I started streaming 2 weeks ago.
My problem is that I also record to file the stream (that option that OBS gives) to edit and upload it to Youtube after but, I check my recordings and no one have audio and if I try to edit a file in SonyVegas, the file doesnt have VIDEO and it appears a single AUDIO track, but with no sound.

I have lost many good moments and i dont know what to do, anyone have a solution?

Thanks

PD: Im very sorry, my english is very simple

Sony Vegas has big problems reading flv files, at least in my experience. I tend to copy those to the mp4 container without re-encoding. FFmpeg just copies the audio and video track over. The mp4 file can then be used in Vegas just fine.
Just make sure you use AAC audio and activate the "Use CFR" checkbox under advanced.
Keep the videos you have saved. Check them in a video player, preferably VLC, NOT windows media player. And see if they have audio and video.
If you then still cannot use them in Vegas, you are probably missing a video codec. I personally use the K-Lite Codec Pack (download the Mega Version) use the dropdown to install "Lots of stuff" with, or without Player. That will install all necessary codecs. Oh, and the installer asks if you want AVG or a similar tool, just choose "I want none of the above" and it wont be installed.

If nothing helps, post us a log file of a test recording please:

Things like this are usually an issue with:

Not using Constant Frame Rate (make sure CFR is set to Yes/On).
Not using AAC audio (don't use MP3).
Not using the .mp4 container (don't use flv).
Using crazy custom x264 settings, like open gop. Don't do this.

Post your OBS log file from one of the times your save to disk isn't loadable in Vegas. If possible upload a sample of video that exhibits the problem to a file hosting site so we can see for ourselves (2-5 minutes long is good), especially if none of the above works.

I tried to convert the video to WMV with another programm and render with SonyVegas and it looks fine.
I opened the video in Google Chrome and it have Video and Audio properly recorded.

I will try that too if something went wrong

Thank you

Remember, every time you re-render your file, the quality goes down, so you want to minimize the number of times you do that. Its best to figure out how to get it to work in Vegas right out of OBS, than putting it through some conversion first.

Just download ffmpeg. (Its a command line tool, but do not worry, its very easy) You put the ffmpeg.exe together with your video files into one folder. In a command prompt, just browse to the folder and enter:

ffmpeg -i video1.flv -c copy -copyts video1.mp4

This will copy both video and audio from video1.flv and create video1.mp4 for you. It should also be a bit faster than reencoding to wmv :)

Isn't it too early to assume he's using .flv? Where did he say that? If he is, that works, because its just changing containers, not re-encoding. But I'd rather just save to .mp4 in the first place, if I don't have OBS crashing issues at least. Saving to .flv and converting can lead to audio-video de-sync issues.

 

[Jack0r]

Saving to mp4 can lead to broken unreadable files if obs crashes for some reason. While the flv container is more capable of still working afterwards. Hence why I recommend recording in flv anyway. Desync can be fixed with Vegas, although I never had that problem :)
And I assumed its flv because mp4, as I mentioned, should work just fine, if he has the right codecs installed.
