DVR also returns a pixel aspect ratio of 1,422222 (which is 64:45) when setting the project to 16:9. And MediaInfo returns 16:9. Seems to be okay that way.

Can you try the latest 0.5.0 connector with DVR?

As far as I know "qpmax" overrules the bitrate limitation. When I disable it I get the ABR bitrate setting.
-
Yes, I noticed that too. In premiere this doesn't happen. I'm not sure how the timecode information is stored
-
I once read opencl=1 should add hardware acceleration (if available) during encoding. But I'm not sure if it does. Still, it doesn't harm nor does it have any negative impact.

In theory QuickSync for h265 is built in already, just the same way as h264 is implemented. But for some mysterious reason it is not finding the hardware encoder profile. I don't know why.

From what I know:
Normally you limit the bitrate only because you want to play that video on hardware decoders. They decode it using a DSP that might have a limitation on max. bitrates, max. resolution, certain h264 features, etc. This is normally indicated by the "level" (e.g. 4.1).
Also if you aim for a specific filesize (i.e. to use the entire capacity of a DVD, BD or even an USB drive) bitrate is important.
For software decoders I wouldn't deal with bitrates at all nowadays. You basically define what quality you want to get and thats all. CRF is doing a pretty good job of finding the right quantizer and the req'd bitrate and all.

On what kind of device do you want to play this video on? Or do you intend to upload this video file to YouTube or similar?

The Voukoder log file: Where do I find the log file?
-
Can you post a logfile with low level debugging enabled?
-
Do you have a sample RED file I can reproduce this with?
-
Well, of course FFmpeg as standalone is faster than DVR + Voukoder, because DVR is rendering the frames before Voukoder can encode them. You'd have to compare:
- DVR export time + FFmpeg encoding time
- DVR with Voukoder export
-
Can you tell me about what was special in that project? Maybe some audio settings?
-
I'm not able to render anything with the latest beta 0.4.1. I get the message: "Render Job X failed as the current clip could not be processed. Cannot add audio clip."
Can you attach the voukoder logfile? Where do I find the log file?
-
this is not my picture but it made by a top-professional colorist. This is a result of ProRes rendering of solid color. Also, he reported some problem with levels (sorry, he did not provide details).
Has that 444 16 bit mode being used for this export session?
-
Well, it depends on the complexity of your DVR project and on your laptop of course. You might want to add your voukoder logfile of that export session to this thread.

The "prores_ks" encoder can only be fed with 10 bit data. So even when it outputs 8 bit data. Yes, confusing.
-
I will most likely rename these types so it is more clear what to choose.
For higher bit depths than 8 bit always use 4:4:4 16 bit. That means: For all ProRes codecs always use this one.
