Export freezes at 99%

[Angelo Lorenzo]

I have multiple clips that are an hour and a half or longer in duration in Redcine-X build 17.27144 on PC w/ a Red Rocket. The first clip in the queue exports to Quicktime just fine while the second will stall at 99%. This has happened twice to me regardless of what clip is in queue position #2. It sucks because the quicktime file is, from all accounts, done but the header isn't written so it's unusable.

Nothing on the forums so far as I can tell, but I thought I'd relate the experience.

Thanks for the information Angelo. What indication do you have that it has frozen? Typically H.264 via QuickTime will give the appearance of stalling right at the end due to the way to the codec works. Eventually it will complete. We also process audio at the end of the export. For clips of that duration these reasons could be the cause of what you are seeing.

Thanks,
David

Like David said, it usually hangs on 99% when it's processing audio. Just let it keep going and you should be fine. The longer the clip, the longer the processing.

This was Quicktime with the Avid DNxHD codec and AJA uncompressed. I will test again over the next few days to make sure it's just the lag for audio processing. The lag was 5+ minutes and redexport seemed to show ~0 processor usage in the task manager.
