Youtube 60fps uploading for non-16:9 content [using VirtualDub]     2019/11/03
by Ami Sapphire


Prerequisites:
*LAV Filters need to be installed before any x264 conversion!*
*videos must be in lossless x264 and original PCM audio first! Check VirtualDub
 hack first!*
*for any game-recorded 60fps videos (ESPECIALLY Kega Fusion videos), do NOT
 change frame rate on the initial video conversion, leave at 60fps!*
*for Kega Fusion videos, its own VFW driver must be installed before initial
 conversion! [This will be a bit tricky on Windows 10 builds post-1607,
 however.]*
*for Kega Fusion videos, for conversion, you cannot use VirtualDub2, only the
 original VirtualDub x86 (32-bit)!*
*VirtualDub2 is required for final conversion as the original VirtualDub only
 saves videos in an AVI container, which is techinically deprecated!


Instructions for VirtualDub2 (after initial video conversion)

1. Video > Full processing mode [if not set yet]

2. Video > Filters...
   * Add... -> resize [if not done already. (This is especially for non-16:9
     resolution games)]
   * Size options: New size -> Vertical resolution should be 720 pixels, e.g.
     960x720
   * Filter mode ->
      * Nearest neighbor is better than precise bicubic (A=-0.75) [or -0.60,
        -1.00] for pixel accuracy, but at the cost of total file size.
      * Precise bicubic (A=-0.75) [or -0.60, -1.00] is better than nearest
        neighbor for total file size, but at the cost of pixel accuracy.

3. Video > Frame rate
   * Frame rate conversion -> Convert to fps: 59.94

4. Video > Compression...
   * x264 8-bit - H.264/MPEG-4 AVC codec
   * x264 configuration: Rate control -> Single pass - ratefactor-based (CRF);
     ratefactor -> 18.0

5. Audio > Full processing mode [if not set yet; otherwise you will get full
   large ADPCM in your video!]

6. Audio > Conversion...
   * Audio Conversion: Sampling rate -> 48000Hz

7. Audio > Compression...
   * FFMpeg AAC
   * AAC-LC configuration: bitrate/channel -> 256k

8. File > Save video...
   * Save as type: MP4 (MPEG-4 Part 14) (*.mp4)
   * Name video as desired filename.
   * Save the video.


You now have a finalized 60fps video converted for Youtube! You can also save
these instructions as a VirtualDub project so you do not have to manually do
these entire instuctions all over again.
