Handbrake Speeding up Video by 9 seconds

[DJ Omega]

So, I recorded some gameplay at 30fps, I rendered it in Vegas Pro at 30fps to a Lagarith Lossless Codec AVI, I put it into Handbrake, choose Constant Framerate of 30, then the video comes out 9 seconds shorter. Any solution?

Have you tried opening it in MediaInfo to check the framerate and other settings? You can post a text version of that here if desired. What's the original total length of the video?

And welcome to our forums.

Hello, thank you for the help. In Vegas the length of the Video is 4m 48s. I put the MediaInfo stuff on Pastebin.com here

EDIT: Sorry if quoting the above post is frowned upon.

Can you post the mediainfo text report for the handbrake export also ?

What version of handbrake ? Did you try one of the nightly builds ?

Ok, so with sound the video is 4m 48s, but, it is out of sync, but with only video it is 4m 34s. The Mediainfo info is here (sound) and here (video).

Given it's an AVI, open it with VirtualDub and check the total number of frames (or check another way if you prefer).

I don't use Handbrake much but it's log file is pretty detailed. It should tell you how many frames it expected, how many it got, how many it duplicated/dropped if need be and the total output. See if it matches up.

Is it possible the video stream in the original AVI is slightly shorter than the audio stream? Do you appear to be missing video anywhere? Is the audio still in sync?

Edit: Sorry I missed yuour last post where you said the audio is out of sync. Try opening the Handbrake output with My MP4BoxGUI or MKVMergeGUI (if you don't mind MKV as it's easier to use) apply an appropriate delay to the audio or video stream and save that as a new MP4/MKV (I'd test with MKVMergeGUI first as it's easy to use) to see if it fixes the audio sync.

Or try an older version of Handbrake (ie version 0.9.9). Maybe it's a bug. There's been a few "what is handbrake doing?" type posts recently.

Just some ideas....

Did you have the "null frames" option selected in lagarith ? Some applications have problems decoding that, and drop frames instead of using a duplicate frame, causing the video to be shorter than the audio

Thank you for the help everybody, I checked the Handbrake log like suggested and found out some frames were dropping so I rerendered it in YV12 and it worked perfectly!

Thanks, It's good to know you found the solution.
