conversion help

[Kracov]

the avc file does not show the red markers that i saw with the original.

[cholla]

Do the XMR & Clever created files show the clipping ?

AVC must be doing something to remove clipping when it converts.

[Kracov]

with XMR both 5.1 and 2ch result in red markers.

[cholla]

Before this topic I did not have XMedia Recode installed.
I had never used it.
So I did some Internet searching for how to correct the clipping with XMR.
I only used XMT for this conversion.
Give this file a listen.If you find it acceptable I will post what I did.

unplayable on ps3. use x264

unplayable on ps3. use x264

The Reign_Of_Fire.mp4 I posted in #94 was created from the Reign Of Fire 2002 1080p BluRay HEVC x265 5.1 BONE.aac
That you uploaded to google drive in post#13.
There is no video so x264 is not an option.

I'm sure I can create an .aac file with XMR.
Does the Reign Of Fire 2002 1080p BluRay HEVC x265 5.1 BONE.aac you created work on your PS3 ?

[Kracov]

ho but i think i had my roommate listen to it on pc.. try the Twister file instead

[cholla]

The Twister 1996 Remastered 1080p BluRay HEVC x265 5.1 BONE_0001.mp4 file does not show any clipping in Audacity.
It also says x265 but MediaInfo does not show that or x264.
How does your PS3 play it ?

I can convert it with XMR & see if it will play.

[Kracov]

oh right that one was converted with XMR/AVC. Here is the original. https://drive.google.com/file/d/1vAee0P1tmustwdNN8NCoNL6CG1gavlL7/view?usp=drive_link

[cholla]

These were done from the file from the link above.

Everything was done with XMR except I had to use Subtitle Edit to read the subtitles OCR from the clip.
That is the first thing I did was created a clip with XMR. So I would have a much shorter file to practice with.
The MP2 file is geared toward the PS3. At least this is what I found for using ac3 with a PS3.
The second is a regular .mp4 with ac3.

XMR's MP4 AV1/h264 option would not complete. I plan to try a few other files with that setting.

[Kracov]

mp2 is inaccessible, and the other mp4 played. it was really bad framerate and choppy. audio may have been okay but not entirely sure.

[cholla]

Odd that the mp2 was inaccessable as that was what was recommended for PS3 from what I found online.
From information on this website:
https://manuals.playstation.net/document/en/ps3/current/video/filetypes.html
PS3 seems to prefer AAC LC audio.
I do not have a PS3 to test with.
For the frame rate I used 23.976 FPS the same as on the original video.
They play smooth on my PC both with VLC & MPC-BE.
I can change the frame rate.
What would you recommend ?

Maybe XMR encodes just do not work well for PS3s.
I'm not impressed much with XMR & as I posted before this topic is the first time I have used XMR.

[Kracov]

they both do play fine on the PC. I will try AAC LC audio

[Kracov]

okay using AAC LC audio on both Twister and Reign of Fire- Reign of Fire played fine on the PS3, but audio was distorted. PS3 said the Twister file is unsupported data. This is really weird. It seems as if XMR requires a lot of back and forth testing in order to pinpoint the perfect audio and video encoders. We should just wait for dave to get back.

[cholla]

The files had some problems.
I will see if I can find the cause.
The Audacity file is OK.

[Kracov]

both files had choppy framerates but audio is likely fine. maybe your PC isn't powerful enough? maybe you got things running in the background that are interfering?

[cholla]

I'm not sure if my PC is powerful enough.
It Has a 6 core AMD processor.
The original video is "choppy" in parts.
Especially the ride in the red pickup.
Other than that the videos play fine on my PC.
I do not run other programs when converting.

Do the videos play choppy on your PC ?

[Kracov]

on the PC they seem fine. however one or both of them may have micro framerate issues. its hard to say. if the original video is choppy for you, then there's some issue with your system. maybe you should post a thread asking how to diagnose your computer. might be a video card issue, maybe you need to update drivers. maybe its Windows 7- that is really old.

[cholla]

on the PC they seem fine. however one or both of them may have micro framerate issues. .

On the PC using MPC-BE I could see the micro-stutter problem in Render Settings/Display Stats.
The fix was setting the Options/Video to:MPC Video Renderer.

[Kracov]

I don't know everything about renderers, but i vaguely remember people saying MadVR is the best, so i've been using that for years. what is your video card? i'm saying this because maybe your pc can't convert properly. why Win7? I put Win10 on a PC from 2014 and it handled just fine.

[cholla]

I tried MadVR a long time ago. I did not like it. So I uninstalled it.
The MPC Video Renderer seems to work well for my OS.
Some way it had been set to: Enhanced Video Renderer (custom presenter) & that was the micro-stutter problem.
VLC did not have the problem when playing the video.
What are you using to determine micro-stutter ?
Or can you just see it ?

My graphics card is : NVIDIA GeForce 7025 + nForce 630a (an onboard card).
This is a screen shot of GPU Z while ffmpeg is encoding a video. It shows no load.

This is my CPU stats at the same time:

Try the video below.

[Kracov]

audio and video seem good on both pc and ps3. what settings did you use?

and that is an ancient video card. seriously, a used 10 year old PC is only $300 and that would be better than what you got.

[cholla]

I used ffmpeg cli for everything in the conversion except for Subtitle Edit.
I had to use it to convert the blu ray PGS subtitles to SRT subtitles so a .MP4 could used them.
The hard part was figuring out how to add the burned in subs. Like in the first Twister sample you posted.

I needed this for a clip to extract the subtitles from.
1.

ffmpeg -ss 00:04:50 -to 00:09:00 -i inputBR.mkv -c:v copy -c:a copy -c:s copy outputBRsubs.mkv

I needed this clip with no subtitles to add the burned in subtitles to.
2.

ffmpeg -ss 00:04:50 -to 00:09:00 -i inputBR.mkv -c copy outputBRnosubs.mkv

This to convert the subtitles to the necessary format. I used SRT but I could have used ASS also.
3. Subtitle Edit outputBRsubs.mkv

I would not have had to do this step but the meta data kept showing the Title as Surround 7.1
It was actually Stereo.
4.

ffmpeg -i inputBRnosubs.mkv -map 0 -metadata:s:a:0 title="Stereo" -c copy outputBRnosubs2.mkv

I'm leaving the path to the subtitle longer as I actually used it because the back & forward slashes have to be correct. Same for the double & single quotes.
5.

ffmpeg -i inputBRnosubs2.mkv -fps_mode passthrough -vf "subtitles='C\:/Users/USER/Desktop/WORK/inputBRsubs.srt:force_style=BorderStyle=3,BackColour=&H80000000'" -c:v libx264 -preset slow -crf 18 -b:v 0 -profile:v main -level 4.2 -pix_fmt yuv420p -x264-params cabac=1:ref=2 -copyts -c:a aac_at -aac_at_quality 0 -aac_at_mode cbr -b:a 256k -ac 2 Twister2ch.mp4

I have my OS set to use ffmpeg in Environmental Variables/Paths.
So I do not have to use quotes around every file.
I also use full paths but those would not help someone using the code in another PC.
So the codes may take some adaption to a differently configured OS.

[cholla]

I gave up on using XMR.
Even when I made settings it did not always come out as I set it to.
It also did not have the aac_at apple codec.

[Kracov]

oh bummer. yeah, no one wants to learn how to code just to convert videos. hopefully dave comes back eventually or maybe i should post elsewhere

[cholla]

no one wants to learn how to code just to convert videos.

There are still many here & elsewhere that code to convert video.
Some even learn to code full scripts in code for software like avisynth.
Also the software designers themselves that write code for the video software.
The main thing is to get the end result you want.

[cholla]

what is your video card? i'm saying this because maybe your pc can't convert properly.

that is an ancient video card

Unless you are playing a video in a software that does this when converting the graphics card is not used.

Using GPU-Z.to monitor my graphics (video) card.
There is no GPU Load when converting with FFMPEG.

If I use a media player like MPC-BE Then the GPU Load is 27 to 33%.

Using Core Temp:
Monitoring CPU use is different a conversion can be upper 80s percent & even bump 100%.
Maybe bumping 100% could cause errors.

[Kracov]

AVC has an option to use GPU acceleration. I have it disabled though.

[cholla]

I installed the version of AVC that works with Windows 7.
It has a option for GPU including Nvidia but it is not available.
Probably because I do not have the Nvidia control panel installed.
The Nvidia show to be working in Windows Device manager
As well as being detected by GPU-Z.
The only time AVC showed GPU Load was when I used AVCs video player.
It showed zero GPU Load when converting.
