multi-cores transcoding HQX to PorRes is supper slow

[nath]

What speed are you getting?

CPU is at 80% and the HDD data at 25MB/s (but this is a bad comparison - because I am onto a different project writing onto different HDD)

Installed v2 ... and yes, now things are looking up. :) Thank you all!

[nath]

So I made the test, and Edius got the CPU up to 92% and the HDD data 200MB/s. It must be the ProRes codec, or the QuickTime envelope that is not supporting multicore processing.

So I did one more test, QuickTime envelope with HQX codec, and see -- see, the CPU is at 89% and the HDD data 188MB/s.

Checking the Miraizon version I discovered I am running v. 1.0.2.1. I will recheck after updating to v2.

HQX QuickTime export is native since Edius version 7.4 & not compareable to Apples QuicTime engine!

Yes - I am using the Maraison ProRes codec.

I am not 100% convinced that the codec is the bottleneck. I will have to test this by going straight from HQX to HQX. If the CPU is still hovering around 8% and the HDD are also still showing 18% usage at about 7MB/s, then it is clear that Edius is only using, and maybe only "seeing" one core!

Is it time to go virtual, to use my 12 cores?

If you are going HQX to PRORES then it will be your PRORES codec which will be slow. Are you using the Maraison codec? Also almost anything using Quick Time on windows will be slower in general. Edius is not slow at encoding overall.

Why is Edius not optimized for multicore encoding? Is it an encoding license issue?

[nath]

Source and destination files are on different drives.
I am on Windows 8 (Windows Defender is on.)
HDDs are utilized up to 18% at about 7MB/s.

[GrassValley_PS]

Activating will do nothing different.

Source and destination files on the same drive?
Anti-virus software active?
File read/write can be a bottle neck at times?

With 12 cores it looks like the system is utilizing only 8% of what the CPU can crunch. I am running the test version of Edius 7.41. Will activating the version speed things up?
