That screenshot you attached hasn't been authorised yet, so "we" can't see what you mean.

Unfortunately, Ripbot is a little restricted.

no GPU Encoding in Ripbot (if you are looking for quicksync encoding = qsvenc, etc...)... Only software x265/4

You probably found the openCL parts in the preferenes, the left one is for x264 - here you can actually offload some of the vector stuff to OPENCL - and the GPU (in your case your UHD770) can then take over some of the stuff that X264 is doing..

With modern CPUs, this is rarely any speed advantage, in most cases much slower than simply running it on the CPU alone.

And its not "GPU Encoding", since it does not touch the dedicated media engines in your GPU.

Ripbot has no support for any hardware-encoder, no AMD, no Intel, no Nvidia.

If you aim for quality and effiecency of encoding (in terms of space vs quality), software encoding is king, anyway. Although GPU Encoders have gotten better over time and are convinient - they are still behind software encoding.

I have some TV Recordings in 50fps, which actually only contain 25fps (frames are doubled)...

For degrain to work properly and to lower encoding time and - of course - get back to the original 25fps, it would be nice to have a switch to "drop every second frame bevor the filter chain"... Is it possible to do this in RipBot ?

Create Custom script with these lines

Code:
#Decimate

Thought i'll try again, is there or will there be any support coming for AV1 Encoding coming, i did a recent check, and to my surprise all the devices in my family are all AV1 capable, didn't think i would see the day (lol), those years have really flown by!

anyway start of new year, and wanted to get the sense for AV1 encoding support....would it truly be a lot of work to implement?

Wishful thinking here, Pulp.

Even tho FFMPEG can easily encode to AV1.

I fiddled around with a process of getting FFMEG to re-encode a freshly RB encoded video to AV1, using that cmd script that Atak added to RB many years ago, but it's a little complicated, and you can only process one complete conversion at once, as the script has to be changed for every different file encoded.

OR

You could do multiple encodes, then run the FFMPEG script separately afterwards.

However, there was a strange issue with the AV1 video's..it wouldn't play properly with VLC, but once it was quickly run thru MKVToolNix, it's "cleaned it up" (whatever it did), made the difference.

But I'm more interested in DV video's, TBH, so I gave up.

Distortion on Playback

Hello all.
For some reason, when encoding movies (Blu-rays and 4Ks), I am getting distortion on some frames. When I play the original ripped file using MakeMKV or Reveal, the file has no distorted frames.

In some cases, it plays:
  • a frame from a few previous frames;
  • I get a static display frame
  • I get a static display frame or the typical colored test pattern.

It is quite annoying, as you may understand.

I've had an issue similar to this years ago, and it turned out to be a memory module issue. So, following the same troubleshooting procedure, I used Mem86 on three of the machines I use for encoding in RipBot.

All three machines tested successfully with no errors.

Can someone please point me in the correct direction on what else I should check?

Thanks in advance!!!

Encoding/Initial Demux Failing Problem

Using Ripbot for a while with all region Blu Rays & 99% things go as expected, but recently I've had some that RipBot rejects immediately at the initial file analyzing stage, all others have been fine.

Maybe there's something causing this during the importing/demuxing/decoding of the video & audio, etc.

You could try updating L-Smash (which is RB's default).

Get it here:-

https://github.com/HomeOfAviSynthPlu...ag/1278.0.0.0/

Or if you have a good nVidia GPU you could try changing the setting for that.

It's plain as day that you must have manually updated eac3to, as that is NOT the default build with RB.

Not saying that might be the issue, BUT it has been stated (a long time ago) that anything other than the default build can cause issues with some Bluray rips.

I run 3.57, but I don't do any (or many) Bluray rips.

So you might have to download RB from page 1, just to get the original eac3to, and copy it in where it needs to go, but rename the current folder (for future reference).

Page 1 link:-

https://www.mediafire.com/file/eke2o...1.27.5.7z/file

OR,

I have uploaded just the original eac3to folder for RB 1.27.5, here:-

https://www.mediafire.com/file/feytb...eac3to.7z/file

OR,

You could try seeing what RB does if you only load the video, and remux the audio & subs back in later, using MKVToolNix.

Good luck.

I was originally using the default install eac3to version when first getting the issue, but updated it today to see if it would make any difference (it didn't!), that's why it's in the log I posted. I'll roll it back anyway - didn't know updating it could possibly cause an issue. Thanks for letting me know.

I did also try just loading the video without the subtitles & audio but unfortunately, with the same results.


I just tried loading the current movie file in question into mkvtoolnix and muxing it, then tried loading that file into Ripbot... And it then loaded it properly without rejecting it! I then tried another problematic title the same way, running it through mkvtoolnix first, and it too will now load into Ripbot successfully! As I've said it's only happened recently with a few disks so not quite sure what's happening...?!

Thanks again for your help, much appreciated!

I'm gonna ask for this again

for this type of audio, 1_audio_English_DEFAULT_DELAY6798ms.dtsma

audio delay is not applied in the final muxing


Does audio delay work for you?

Hi, so how do you know that your audio is out of sync ??

I'm sure there is an option to adjust this within RB, but I think it's a manual thing.

I don't have too many sync problems, and if I do, I do a quick run thru MKVToolNix, (with adjustments) until it's back in sync.

What do you mean??

DELAY6798ms was introduced in the filename to apply later in muxing

So, if you were to process this, are you expecting a sync issue, or do you expect RB to auto adjust it somehow ?

I mean, that's nearly a 7 second issue!!

DUDE !!!

I read it, but maybe it's the way you wrote it, that is confusing.

So, is it just dtsma, or ALL audio?

I have never noticed a delay is auto fixed in RB.

I did have one instance that unbeknown to me, a delay HAD been introduced by RB, and it stuffed everything up until I manually adjusted it.

It is strange that what appears to be a perfectly in sync video/audio, once it's demuxed, it's not.
