Hello, I used to encode videos to x264 with One Click Encoder, Constant Quality, in x264 config page, of around 22.0, and this 30 minute tv recording used to come out to around 900+ kbps and 200-250 MB. I encode the same exact show and now the end result is 600 kbps video and 70-80 MB and the video looks super bad.
Was there a recent change to the profiles or something? I ask because I recently upgraded MeGUI from 2828 to 2913. First time I upgraded it in like 2+ years I think. I am wondering if this related. |

https://forum.videohelp.com/threads/...rent-filesizes Maybe the bundled x264 is broken, or whatever MeGUI uses to pipe the script output to the encoder these days (ffmpeg?). I'm still on XP and for 32 bit windows there's no middle man. The script output is piped directly to the encoder. I'm using MeGUI 2913 though, and the file sizes are fine (although I think I rolled x264 back to the previous version as the bundled one no longer runs on XP). I'd suggest rolling x264 back to the previous version and if that doesn't fix it, try rolling back ffmpeg or whatever MeGUI uses these days, assuming you're running a 64 bit version of Windows. 32 bit MeGUI encodes with 64 bit x264 on 64 bit Windows, and I think it uses ffmpeg to pipe the video to the encoder. I've no idea if the same applies to the 64 bit version of MeGUI. Last edited by hello_hello; 1st February 2021 at 16:44. |

Hi,
1) I want to re-encode a lot of video files (FROM mpeg2-mkv TO avc-mkv). The only requirement is: output bitrate should be half of original (i.e. twice smaller). All original files has different bitrate, so output bitrate should be calculated somehow. But how? 2) How to preserve tags (Movie name, Released date, Comment, DIRECTOR, Url, WRITTEN_BY) from original mkv-files? New encoded files doesn't contain these tags. Thank you in advance! |

Go,
This don't comply with your requirements, but as no-one else replied I thought might be something to play with. Maybe you can make some use of it. Go.Bat [see REM's ie REMarks] Code:
REM We DO NOT LIKE SPACES IN FILE NAMES (REM == REMark ie comment) REM We DO NOT LIKE ACCENTS IN FILE NAMES. setlocal REM Where to Find ffmpeg set FFMPEG="C:\BIN\ffmpeg.exe" REM Where to get INPUT files, No terminating Backslash, "." = current directory (ie same as dir .bat file) set INDIR="." REM Where to place OUTPUT files, No terminating Backslash. "." would be same as .bat file, ".\OUTPUT" = OUTPUT folder in same directory as bat file. set OUTDIR=".\OUTPUT" REM OUTPUT:- Video: codec=x264, Preset=Slow, CRF=23, Audio: aac 96Kb/s, Output in mkv container SET VCODEC=libx264 SET PRESET=slow SET CRF=23 SET ABITRATE=96K SET CONTAINER=MKV REM Below, can add INPUT extensions as eg *.avi (SPACE separated, Batch Processes all INPUT type files in INDIR) FOR %%A IN (*.mpg *.mpeg *.mkv *.mp4) DO ( %FFMPEG% -i "%INDIR%\%%A" -vcodec %VCODEC% -preset %PRESET% -crf %CRF% -acodec aac -b:a %ABITRATE% "%OUTDIR%\%%~nxA.%CONTAINER%" ) Pause

Maybe memory access violation, I would take a look in Windows Event Viewer, maybe it has a log telling in which module it happened. It can be an avs or filter or hardware or source file issue.

Event Viewer didn't record anything, but it was able to finish rendering when I had deinterlacing turned off. This is fine except the whole reason I'm using the current script is that I'm trying to deinterlace the footage.
New Script: Code:
LoadPlugin("E:\MeGUI-2913-64\TDeint.dll") LoadPlugin("E:\MeGUI-2913-64\RgTools.dll") LoadPlugin("E:\MeGUI-2913-64\nnedi3.dll") LoadPlugin("E:\MeGUI-2913-64\DePanEstimate.dll") LoadPlugin("E:\MeGUI-2913-64\DePan.dll") LoadPlugin("E:\MeGUI-2913-64\mvtools2.dll") LoadPlugin("E:\MeGUI-2913-64\masktools2.dll") LoadPlugin("E:\MeGUI-2913-64\tools\lsmash\LSMASHSource.dll") LWLibavVideoSource("D:\Video\1.mkv") #deinterlace crop(238, 6, -238, -2) #resize #denoise import("E:\MeGUI-2913-64\SMDegrain.avsi") import("E:\MeGUI-2913-64\QTGMC.avsi") QTGMC( Preset="Slow", SourceMatch=3, InputType=1, Lossless=0, TR2=2 ) |

Hi,
My source audio is AAC 128kbps VBR and I'd like to slow it down from 25 to 24 in MeGUI, but I want to preserve the original bitrate with VBR and MeGUI only offers "quality" adjuster for VBR. Is there no way to set the target bitrate? I could just set it to 128 CBR, but I don't know if it's appropriate to re-encode VBR to CBR (not sure if there are drawbacks). |

And my secondary question was, when converting from VBR, is it always best to convert to VBR, as opposed to CBR? I'm doing these conversions because I care more about preserving the cinematic FPS (24) than dealing with a small loss in audio quality, which most people couldn't even hear.

The way recommended to encode aac at a fixed average bitrate is use the Constrained mode (CVBR) of qaac.
You need install the package in MeGUI, and Options -> External Programs -> Enable QAAC

Hello all,
Sorry in advance if this was answered already. I've started dabbling with some 4K HDR10 movies and found MeGUI doesn't seem to be handling them properly. The color output looked dull and washed out. Did some quick research and found some info that makes it seem as though the source isn't be treated as a full 10-bit source. Is MeGUI even capable of handling these movies? I'm trying out another encoder, Fastflix, that seems to have been written primarily to deal with this issue. |
