AV1 encoding very slow (handbrake and Vidcoder finish in 10 seconds, Vidcoder allmost 3 minutes
Problem Description
When encoding to AV! the encodings process slows down after a while, the fps drops down very much. When using Handbrake and Shutterencoder with the same settings the proces is must faster. (20 times faster) But all the settings are the same (speed 12),i do encoding for many years, and im pretty sure this is a bug. I noticed Handbrake and Vidcoder uses a different version of (Aomedia) AV1 codec. Perhabs that explanes why Vidcoder hangs (and the others dont). Version 8.25 Strange thing is,i tryed many versions, older and beta's they all have the same problem (for me that is). Regards John
What version of VidCoder are you running?
8.25

I think i found the problem. I have imported the same file in vidcoder and Handbrake, and i saw that the audio settings were very different. I have changed the setting in vidcoder to mirror those in Handbrake, and since than i tryed multiple files, no problem. But this is not correct i thinkt, Should't the program choose the correct audio settings, like Handbrake does? Well anyway, it works now (it seems). Hope it will remain problemfree.
VidCoder actually imports the same built-in preset list that HandBrake uses. Though there is a conversion step so it's conceivable that something went wrong there. Which built-in preset did you see have different settings, and what settings were different?
Hi. It seems i used the wrong settings. Only tomorrow i saw there is a AV1 Matroska setting (yes thats dumb haha), prior i used some other h265 preset and modified videosetting (like choosing av1 etc) When using the AV1 Matroska settings, the problems are gone. everything work perfectly. But (maybe im doing something wrong) i saw when you choose AV1 Matroska in HB and VC preset, the audio settings in HB and VC are different by default. (HB and VC new install, so no customised settings). Maybe you can have a look at that.
By the way, the Dutch translation is outstanding, it really couldn't have been done better, but i noticed a very very tiny thing that could be improved. (yes i'm in nitpicking modus haha)
[image: Rate.jpg]
The Dutch translation from English to Dutch for Max framerate (VFR) is Max framesnelheid (VFR), so thats perfect, no errors there. But Constante framerate ("framerate" is still in English) should be "Constante framesnelheid)" ("framesnelheid" being the Dutch word for framerate).
Well thanks for your time and regards! John

I updated that string, it will come in the next time I pull in translations. You can also directly translate at https://crowdin.com/project/vidcoder .
I checked out the AV1 HandBrake preset and did a test encode with HandBrake and VidCoder and didn't notice any significant speed difference, and the audio settings were just about the same. VidCoder exposes the Compression level UI, which the HandBrake UI does not do. However, VidCoder defaults to "10" as the compression level for this preset, and that's what HandBrake picks as well when no compression level is specified.
What audio preset differences did you notice?
