When during conversion PC go to suspend and later resume then duration of converted video is shorter and audio is out of sync.

Source video is mpg (resulution 720 x 576) and destination video is mp4.
Source video has duration 10:00 and destination video only 09:56.

Used profile is H264 MP4 with these changes:
- General - Encoder: Intel Quic Sync
- General - Output Mode: Force Recode
- Video - Resolution: SAS x SAS
- Video - Avg Bitrate: 2600
- Video - Max Bitrate: 15000
- Audio - Encoding Type: AAC
- Audio - Allow multiple audio streams: Disabled

--------------------------------------------
When PC don't go to sleep during conversion all is ok.

When don't use codec Intel Quic Sync and reencode only audio (video is copied to output without change) then audio isn't out of sync and video has full length, but output file is not binary the same as the video converted without go to suspend/resume PC during conversion. Is it normal? Is it valid output?

Did the PC automatically go to sleep or did you do it manually. I thought that we suspended auto sleep while output is in progress. If that's not the case we can look into it. Which OS are you running?

However, if the PC does go to sleep during output and then resumes I don't think we can control the status of the output file.

I'll have to see if there's anything we can do about that, I'm not sure. May I suggest that if you are doing an output and want to put the computer to sleep manually click on the Pause button so we can resume when you bring the system back up.

Hm, but how to pause/resume creating the output file through COM object VideoReDo5.VideoReDoSilent ? Exist any function for this? I want use this COM feature and occasionally go to sleep manually.

Or can you add to internal cycle, which creating output file, automatic pause conversion when operating system go to sleep? Operating system Windows send broadcast message all applications before go to sleep and when system wake up.

Application Movavi Video Converter which use Intel Quick Sync too don't have with go to sleep problem. Output is exactly the same as without go to sleep.
