Videos should be as small as possible, as this makes them load faster and reduces server load. However, this should not come at the cost of clarity. If a video doesn't effectively communicate what it means to, then it being small is irrelevantâit's useless.
The easiest way to ensure a video is small is to make it shorter. Most videos on Wavu Wiki should be around 2 to 5 seconds long. Be ruthless in cutting out dead time from a video.
For a tutorial on how to record, trim, and encode videos, see Wavu:Video recording tutorial.
Encoder parameters
These parameters are chosen such that all relevant text renders on the UI are legible, while optimizing file size and video quality at both down-scaled (thumbnail) and up-scaled (full screen) resolutions.
| Encoder | x264 |
|---|---|
| crf | 25 |
| Preset | veryslow |
| Frame rate | 60fps |
| Resolution | 640x360[1] |
| Container | mp4 |
| Audio track | None[2] |
Graphics settings
Use the best graphics settings your computer can handle without compromising the frame rate.
Map settings
Be careful recording on Infinite Azure, since sometimes there's a massive lens flare which makes text not legible after encoding.
Any stage is permitted, but advised not to use stages with red color grading (Jungle Outpost 1, Twighlight Conflict 2, Devil's Pit, Brimstone and Fire, Howard Estate, Vermilion Gates) unless you have a no-colorgrading mod for needed stage, or the stage is required for demonstration. Know that most stages have an appropriate alternative. Stages with snow-like effects are advised not to use, unless there is a mod removing it, or the stage is required for demonstartion (Arctic Snowfall, Dragon's Nest final round, Helipad night, Howard Estate post balcony) Dark stages should also be generally avoided.
As general rule, unless needed otherwise, stage is chosen from the pool of:
- Forgotten Realm
- Jungle Outpost 2
- Twighlight Conflict 1
- Dragon's Nest no rain
- Souq
- Duomo Di Sirio
- G.Corp Helipad (day)
- Precipice of Fate
- Geometric Plane
- Infinite Azure 1 or 2
- Hammerhead
- Last Day on Earth
Other stages are permitted, it's just an advice to keep the visuals clear. Red stages do not provide visual clarity on a lot of screens, rain, snow and alike may mess with compression algorythms, making videos look uncomprehensible, dark stages may just be too dark to see the demonstration clearly
Encoding efficiency
Map choice has a substantial effect on the filesize of a video after encoding. Backgrounds with complicated or moving parts require more data to be encoded at the same quality level.
The following tests were done by recording Kazumi on P1 doing f,F+4 f+3,F RSS.2 d/f+1 b,f+2,1,4 S! f+3,F RSS.1 against a Heihachi bot, with each video being 7 seconds long and encoded with x264 crf25 640x360@60.
| Map | Bitrate (kb/s) | Ratio (vs best) |
|---|---|---|
| Infinite Azure 2 | 2223 | 1 |
| Waiting Room | 2319 | 1.04 |
| Infinite Azure | 2442 | 1.10 |
| Brimstone & Fire | 2647 | 1.19 |
| Arctic Snowfall | 2868 | 1.29 |
Action settings
If your video is demonstrating a move, use these action settings so that readers aren't mislead into thinking combos exist where they don't.
| CPU Opponent Action 1 | Stand |
|---|---|
| CPU Opponent Action 2 | Guard All |
| Ground Technique | Side Quick Roll (Left) |
| Stand Up | Wake Up (Backward) |
Display settings
Most videos are recorded from practice mode. The UI here should display only the information relevant to the video's purpose.
These display settings are appropriate for most videos.
| Command History | Display |
|---|---|
| Health Gauge | Hide |
| Player Attack Info | Display |
| CPU Opponent Attack Info | Hide |
| Hit Properties | Display |
| Recovery Animation | Hide |
| Player Frame Info | Hide |
| Opponent Frame Info | Hide |
Player Frame Info and Opponent Frame Info should be set to Detailed Display if frame data is central to the video.
Character set up
As default, videos should be from P1 perspective, unless demonstration requires P2.
Characters should be using their default P1 costumes, unless demonstration requires otherwise.
Rage should be off unless Rage is required for demonstration.
P2, unless needed otherwise, should be a normal sized character, Jin, Heihachi, Kazuya or Shaheen.
