This little post will try to explain how to easily upload cool sakuga clips in good quality for new users.
First, some "rules" that are good to try and follow if possible:
- Don't upload screen-recorded clips. By that I mean any type of clips that were captured with screen-recording tools/software. Things like "Fraps", "OBS", etc. are to be avoided at all costs. Screen recording clips will cause many problems, like lower video quality, incorrect frame rate, wrong color space, etc.
- Avoid using "online" encoding tools. They are generally poor quality and often cause the aforementioned problems.
- Don't use incorrect framerates sources. There are exceptions**, but as a general rule of thumb, the vast majority of animation sources are 23.976 FPS, so try to use ones that match this. Incorrect framerates can introduce big problems like stutter or incorrect frame pacing.
**Some sources use a variable framerate and some old Toei shows are natively 29.976 fps.
If you have doubts about the framerate of your clips, don't hesitate to ask before uploading. There are many regular uploaders that will gladly try to help you.
- Use the correct aspect ratio for your uploads. Most animated series/movies are 16:9 which mean it needs to be a resolution of 854x480.
Be aware of 720x480 as this is incorrect and simply the anamorphic container format found on DVDs. Your video player will automatically correct this to 854x480, but this must be done manually for the booru.
4:3 format should almost always be uploaded at 640x480.
The only exceptions to these rule are if media uses a non-standard aspect ratio such as 2.35:1 (1128x480). This is very rare, however.
- Try to always use raw sources. Avoid re-encoded sources from illegal streaming sites, YouTube fan videos, etc. These will almost always be far too low quality for booru standards.
- There are many easy-access options for raw sources. Many official streaming services offer direct download of their episodes or you can torrent direct rips. Alternatively, physical DVDs and Blu-rays will generally provide adequate quality.
- Please always use the native resolution of the media as a starting point. Although the clips on this website are limited to 480 pixels in height, downscaling from an HD source to 480p will provide superior quality. Please avoid upscales of SD footage, however, as it is rarely done right.
- Due to the nature of the industry, corrections for home video are incredibly common. If you're approaching a show after it's been released on home video, it's best to avoid the streaming versions of these shows as they typically only host the original cuts, missing the altered/reanimated/corrected versions found on home video.
- With web series becoming more common, there are often series exclusive to YouTube, and in that case, mods will understand that there are no better sources available. Please do try to check carefully that there have not been home releases, however. YouTube's compression is aggressive, resulting in macroblocking, color banding, and sometimes the wrong color space.
- YouTube uploads are often in the wrong framerates, even from official uploads. It's common to find creditless versions of OPs and EDs from official sources on the site, but we politely ask that you wait until the official home release where it's almost guaranteed to be free of issues commonly associated with YouTube.
With general guidelines out of the way, let's touch on the best software for encoding clips for upload!
MeGUI in combination with AviSynth/AvsPmod are also great tools to use, and allow you to correct problems when the source you're using has issues. This is only recommended for very advanced users.
Another option is the fan-made Sakugabooru Encoder (https://www.sakugabooru.com/forum/show/104). It's fairly simple to use - you simply enter in the timestamps for the start and end points of the clip you're after - however it lacks any visual indicator that you're being frame-precise. If you use this method, we recommend changing the CRF (Constant Rate Factor) from the base value of 20 to somewhere between 15 and 18. This will ensure adequate quality.
To do this, right-click on the application, open it with Notepad, and change the number next to CRF to your desired value, and then save.
- Colors setting:
There are 2 different type of colors settings you need to pay attention when you encode clips for the Sakugabooru. HD sources, like recent TV serie/Movies/Blu-ray etc need to have the "BT709" colors matrix tagged on your video. Not all encoders automaticly does it, for example if you use the lastest version of Avidemux you need to set it manually. For that, go to video output > clic on configure > go to the very last tab (called "output 2") you'll see 3 options: "colour Primaries" / "Transfer Characteristic" / "colour Matrix", set all 3 to "BT 709 (HD)". Now all your video clips will be tagged BT709 and will be displayed correctly on the booru.
For SD source,like very old TV shows, VDs,etc, the videos need to be tagged BT601 (SD) to have the right colors. In that case you don't need to modify your encoding settings at all, the Sakugabooru by its nature of only allowing SD video will automaticly display the SD colors as intended.
Be carefull that if you are encoding a SD source after having encoded an HD source, you need to remove the BT709 tag mentionned earlier from your encoder, or the video will be tagged with HD colors (BT709) wich will be incorrect for an SD source. Follow the same steps as before and go to your encoding settings but this time tag the 3 options as "unknown".
When you are done encoding your clip, be sure to always check it over before uploading to be sure your upload is problem-free.

One of the most user-friendly software available is Avidemux. You can find an easy guide to follow here (https://www.kanzenshuu.com/forum/viewtopic.php?p=1122872#p1122872). Be sure to use the latest version to avoid any possible issues!
MeGUI in combination with AviSynth/AvsPmod are also great tools to use, and allow you to correct problems when the source you're using has issues. This is only recommended for very advanced users.

When everything is done you can upload your clip on the booru following the tag guidelines: https://www.sakugabooru.com/wiki/show?title=tag_guidelines
