A slightly different approach that results in another kind of not expected behaviour
Source Material is HEVC (H.265) MP4 1080@50 ALL-I
- created Subclips on the orginals with keep extend
- rendering Proxy Material results in incomplete Proxies
- It seems that when there are multiple Subclips on one source, it's generating Proxies only for one Subclip (when rendering Proxies in one run)
- Multiple Subclips on one Source, when rendering all Proxies in one run, results only in one being linked to the Proxy
- Trying to regenerate full Proxies on the imported full Sources results again in incomplete Proxies
This Error behaviour applies only to subclips which are creeated with the "Use full clip extends" Option unchecked.
Multiple Supclipse on one Source with the use option checked are working fine and are linked to the same Proxy file.
So for the time being I will keep the option checked, eventhough this results always in lots of longer Proxies and Render Time.
Just as a Hint to all other Users:
If you enable the Columns Proxy and Proxy Path in the Media Pool Listing, you will see the Subclips Proxies named with a _S000, _S0001 Name Suffix. These seem to represent the Subclips Proxies when "Use full clip extends" is uncheched.
It might be that this somehow gets tangled up when generating the Proxies and having more than one Subclip on one Source.
