displayname Posted November 29, 2021 Share Posted November 29, 2021 I've been using this program for about 6 months now and have not had an issue. About a month ago I started running into issues where the output files audio did not match the video, it's off by anywhere from 1 to 5 seconds. Methodology: 1: Open a h264 video file 2: Click Export Video 3: Choose Video File, Set encoder settings to h265, Video: High Quality, Audio: High Quality, Preferred number of channels: same as input 4: Click Create, wait for about the length of the video. (1.5 hrs, wish there was multi-threading) 5: Play video in VLC, or any other playback software. Audio is mismatched from Video. Anyone have any insights as to what is going wrong? Most of the h264 videos are 5.1 surround movies that I'm ripping from our BluRay collection to go on our Media PC. The h264 videos play without any issues. ANY help would be GREATLY appreciated!

borate Posted November 29, 2021 Share Posted November 29, 2021 Share a file that does this and someone will take a look... Upload the file/s to a free server, such as Google Drive or MS OneDrive, get a shared (public) link, copy the link and paste it here or to me in a Private Message via the mail envelope in the top-right corner of this forum. When using Google Drive, if necessary change "restricted" to "anyone with link can view." Link to comment Share on other sites More sharing options...

borate Posted November 29, 2021 Share Posted November 29, 2021 Last info was that H265 doesn't support graphic acceleration in VP. And H265 is indeed out of sync. Use H264. Better still, export as LOSSLESS. A world faster, higher quality. Suggest that NORMALIZATION be applied to the audio track; it's low. That completed in just a few minutes in 11.01 and the result was in sync and excellent in Media Player Classic, BE. Link to comment Share on other sites More sharing options...
displayname Posted November 29, 2021 Author Share Posted November 29, 2021 Thank you so much for such quick responses. 🙂 Thank you for the NORMALIZATION information. The main reason for my going to h265 was file size. Going from h264 to h264 doesn't really gain me anything. A 3.5G file is still a 3.5G file. When h265 WAS working it would take a long time, but the file size would go from 3.5G to 700M. Any reason that h265 stopped syncing the audio? I was using this process for at least 6 months before it stopped working. Link to comment Share on other sites More sharing options...
borate Posted November 29, 2021 Share Posted November 29, 2021 Had you changed versions when it stopped working? What version succeeded earlier? Were earlier files the same multi-channel rips from BR. This has been reported. Please leave the original on the server for a few days so it can be accessed. Thanks.

displayname Posted November 29, 2021 Author Share Posted November 29, 2021 I had changed version, typical update. I do not remember which was the last working version. Thank you again for the help, and for escalating this for me. I'll leave the file there until this gets resolved. Link to comment Share on other sites More sharing options...
borate Posted November 30, 2021 Share Posted November 30, 2021 Thanks for sharing the file, which was tested a number of times here, and by a developer. Every one of my runs was in sync, the last using 11.01 with your HQ settings. See my Personal Message (click the envelope at the top-right of this forum) for the result. So, inconclusive and unable to replicate with the current release version. Link to comment Share on other sites More sharing options...
displayname Posted December 1, 2021 Author Share Posted December 1, 2021 Thank you for looking into this. I'll have to go through all the settings and see if I'm missing something, because I have run this 4 times and never got the audio to sync. Again, thank you for the fast, accurate, and helpful responses! Link to comment Share on other sites More sharing options...
borate Posted December 1, 2021 Share Posted December 1, 2021 Though it seemingly was in sync here, the developer has checked in to confirm there is indeed a subtle slip. Too subtle for me?😗 A bug has been filed. Watch my export in the PM message and see what you think. Test exporting at default quality (lower the file size) and report results.

displayname Posted December 1, 2021 Author Share Posted December 1, 2021 I looked at the file you posted, it seemed to have the same mismatch as all the others, so I thought, what if it's VLC! I downloaded MPV from SourceForge, an open-source video player, and there is no mismatch! Sooo, I guess that the issue might have been VLC all along. That will teach me to think that the most popular video player works the best. Again, thank you for all the effort that you did for me, if I had not gone through this process who knows how long I would have thought it was VideoPad.

borate Posted December 1, 2021 Share Posted December 1, 2021 Humm, that's interesting. There is a subtle slip - just milliseconds - but it escapes me when viewing the linked HQ video with MPC-BE. The default quality settings don't seem to produce that offset, which is being investigated. Thanks for passing along the info. Link to comment Share on other sites More sharing options...
borate Posted December 8, 2021 Share Posted December 8, 2021 This should be fixed in the latest version. Give it a try. Link to comment Share on other sites More sharing options...
