Essentially a perfect resizer that is artifact free (see ). Spline64Resize is typically better than Lanczos, Bicubic, and Bilinear. I did some sharpening with CAS (brand new algorithm by AMD, that often works better than older methods). This is also a very handy was to easily change the framerate (like if you’re doing a PAL 25fps video that was shot on film at 23.976fps):Ġ Change the image folder, fps, and end frame to suit. Notes I keep (yes this is the 4th try… my first run, the QTGMC setting were too soft, limiting upscaling, 200 percent didn’t provide the detail I was after) Note my filenames clue me in to what processing was done:Ġ1c-lg480p-23.976-720x480-qtgmc-fast-slower-ezdenoise=5-noiseprocess-1-TR0=1-lag.aviĪfter that finishes, open the avi in VEAI and upscale (I use 1.6.1 due to blocking artifacts in 1.7.1, and Gaia-CG is by far the best model in 1.6.1 (IMO)). Set to Lagarith compression in Vdub2 and Save video. Whether to use AssumeTFF or AssumeBFF depends on what Mediainfo tells you- look the at original video file with it, it’ll tell you the field order. Note I disabled audio in Virtualdub2 and VEAI. That does an IVTC and a high quality deinterlace, outputing 23.976fps video. QTGMC( Preset=“Fast”, EZDenoise=5, NoiseProcess=1, NoisePreset=“Slower”, TR0=1 ) Likewise, Huffyuv is interlaced only.Ġ1c.avs (filename to be opened in Virtualdub2, and processed by Avisynth, use any text editor like Notepad to create avs files) Lagarith is progressive only (despite what its documention says). Note I used Huffyuv at this point rather than Lagarith as it’s faster and works properly with interlaced. This is after demuxing the mkv file with MkvExtract (which also creates your audio file you’ll need later). But I’m not touching 1.7.1 because of the blocks in video issue."Įxample AviSynth scripts for a 480 29.97fps telecined interlaced DVD with a bit of noise:Īll the standard MPEG2 source filters failed to find the correct frame count, so I used VirtualdubMPEG2 to open the mpg and save as Huyffyuv avi. I think someone mentioned here that 1.7.1 can open Avisynth scripts now. Feed VEAI only Lagarith or RGB avi files (one person here has success with image sequences). For MPEG2, sometimes the frame count is wrong with all source filters (you’ll know because of AV sync issues later), and I have to use VirtualdubMPEG2 and save to Lagarith avi. I use Virtualdub2 + Avisynth and a proper source filter like DGMPGDec, DGAVCDecNV, DGAVCDec, and save as Lagarith avi. They appear to be using something similar to Avisynth’s DirectShowSource which has issues with AVC and MPEG2. Another reason to demux and remux with the original audio. If is was 5.1 channel, it won’t be after VEAI. If you do try to use audio in VEAI, it reencodes the audio to AAC stereo (I forget the bitrate). You should upscale your whole video, not work in sections.Īudio must be demuxed from the video before VEAI and remuxed back in at the end with MP4Box or MkvMerge. I also do any final tweaks with Avisynth and Virtualdub2 before saving the mp4. I use Avisynth’s ImageSource function to import the pngs into Virtualdub2. I use the png image sequence option and then encode with x264 in Virtualdub2. There is currently no way to tune the mp4 encoder other than bitrate. Disable it and you can also leave it out of your source file.
