Overview
How to render your SFM video in the best possible quality
Setup
SETTING UP: To squeeze the BEST quality of a 1080p video onto youtube, the final video will need to be 1440p (youtube gives us a better bitrate at 1080p if the max quality is 1440p). BUT to do this, SFM refuses to render at 1440p, we’ll have to render at 4k by doing
“Right-click Source Filmmaker, click Properties, click the SET LAUNCH OPTIONS button, and add -sfm_resolution 2160 -w 3840 -h 2160 to your command-line startup options.”
We will downscale this to 1440p in virtualdub later.
OR: Just render at 1080p and resize to 1440p if you dont care about having true 1440p, and just want a good looking 1080p.
Instructions
1. Render your video as an image sequence (png)
2. Adjust your shutter speed. Take your framerate times 2, and and divide by 1.
24fps = 1/48 = 0.02083
30fps = 1/60 = 0.0167
60fps = 1/120 = 0.00833
SFM will round these numbers.
3. Download VirtualDub[virtualdub.sourceforge.net]
4. Drag in the the first frame of the image sequece.
a) Go to Audio > Audio from other file. Select your audio.
NOTE: To be in sync go to the VERY END of the last clip by hitting the down arrow, then the right arrow.
Your audio length should be EXACTLY the number at the top (audacity is a nice tool for this)
b) set the Framerate by goin to video > framerate > “change so video and audio durations match” (It should be EXACTLY 24/30/60 etc. No decimals such as 60.002, etc.)
c) Video > Compression > Lagarith Lossless Codec (this’ll be a very large file)
c2) (still in the compression tab) Configure > mode > YUY2
NOTE: RGB may be better, use it if you have a lot of dark scenes/dark compression artifacts
d) Video > Filters > Add.. >resize
e) File > Save as .avi
5. Download Handbrake[handbrake.fr]
6. Go to import, and import this preset (PRESET DOWNLOAD[drive.google.com])
7. Render using this preset
If your audio is more complex, just render the uncompressed video, put in you favorite video editor, add your audio, re-render uncompressed, and follow the handbrake instructions.
NOTE: I’m not an expert in doing this, these are just the best settings I’ve had with 100s of hours of messing with rendering options.
Let me know if you’ve found a better handbrake preset for youtube.
