Vegas - no preview after restart

szerwony wrote on 8/24/2016, 7:48 AM

Hello. I have big problem with Vegas 13. I was editing videos with no problem at the beginning. But when I made short, 2 second parts, and then restarted Vegas, preview doesn't load and rendered video is black. When I work with 1-2 files, I can easily repair it by dropping them again on timeline, but with that amount of files this doesn't work. Does anyone know how to fix it? I need to finish this project fast.

Have you tried removing GPU processing for preview?

'Options > Preferences > Video > GPU acceleration of video processing...' set it to 'off', then close and restart Vegas.

Also, use 'CPU only' for your renders if you are using the 'MainConcept AVC' or 'Sony AVC', as a trial to determine if that helps.

Additional information may help, system specs, Vegas version abd build number, MediaInfo (text format) of the source media and render file, screen shot of your project settings, as well as, the render template.

And what is strange, sometimes I can see one frame of the clip at it's beginning, but next frames are black. It's sometimes working like this when I drop whole video somewhere on timeline and then delete it.

Hi... i think it's more a Preview Device problem, check Preferences > Preview Device and make a screenshot, also when you have no Preview try to set the quality on Best (full), just play around, also i see that you have your thumbnails set to head, center,tail (Preferences > Video > Thumbnails to show in video events) set them to All, this shouldn't make any effect on the preview window, but who knows..it's W10 ;)

szerwony wrote on 8/25/2016, 8:18 AM

If it would be only preview problem, then rendered video should be okay, but it also isn't. I did what you said, but this didn't help.

Preview device preferences:

SphinxRa40 wrote on 8/26/2016, 5:21 AM

Yes i read the beginning again, pretty bizar, it makes sence that rendered video's are black to as there isn't anything to render, did you try other video formats (.mkv....mov...etc.), if those formats have a preview you can atleast know it's maybe the avi files, if i understand it all right one or two avi files the preview works and with alot not (like show on the pictures)? device preferences are same as mine btw. trying todo same thing here with avi's for you but can not think of anything else, if .mov or whatever works, and one avi is black maybe you can send it to me so i can have a better look...(unless it's not with 1 avi thats why i asked)

AVC plus PCM in an AVI wrapper is pretty exotic. As suggested, try some other formats if you can. It would be interesting to see what plug-in in Vegas is decoding the file. Right click on the file in Vegas Explorer window, choose Properties at the bottom, and copy and paste the results here. There is probably a free utility somewhere that could rewrap your files from AVI to MP4, and that might help.

NickHope wrote on 8/26/2016, 5:45 AM

Also, a good practice with black frames is to restart Vegas immediately before your rendering operation. Don't do anything else in it before you render. Probably a good idea to reboot the computer before that too.

What kind of  footage is here edited? I see avi from the snapshoots, but what is the codec in the avi? It could be that you work here with a codec that makes problems in Vegas.

It says AVC (H.264) encoded with x264 in the MediaInfo info. But there are many flavours of that and the exact encoding settings aren't shown.

Wolfgang S. wrote on 8/26/2016, 6:28 AM

But is is footage from a camera or from another source? H.264 can be a lot of things.

does the video preview using the trimmer, also try disable resample and see if it makes any difference..

NickHope wrote on 8/26/2016, 7:06 AM

It says it's from Bandicam, which is a screen/game recorder.

One solution found here is to try to rewrap the files to MP4 using ffmpeg: http://ffmpeg.zeranoe.com/builds/

Usage:

ffmpeg.exe -i "input file.avi" -vcodec copy -acodec copy "output file.mp4"

Or you can perhaps use AviDemux. Note John Rofano's advice on this thread to use version 2.5, not 2.6. Not sure if that's still the case as it's a couple of years ago. I would try 2.6 first if you go this route.

And that is exactly the problem - it is not from a camera, but Vegas was build to edit camera footages. So I agree with you that the solution will be a kind of conversion with a 3rd party tool, to be able to edit that in Vegas.

Fair enough, I think there will be also other tools that would allow to edit such a type of footage without conversion too. But I do not know what tool should be recommended here. A general conversion tool would be TMPGenc Video Mastering Works 6, but that does not come for free.

handbrake?

szerwony wrote on 8/26/2016, 4:12 PM

Thanks for help, I converted those AVIs to MP4 with Freemake Video Converter, then replaced in Vegas and it worked. AVIs were recorded with Bandicam. It would be nice if it was problem only with files from Bandicam, but I think it isn't. Some time ago when I was making video from my holidays, I had same problem. It was in MOV, recorded with SJCam SJ4000. I managed to render it by copying all files to my brother's computer, where it fortunately worked.
