## Prepare videos
If you are advanced user, see [Recommended resolution](https://github.com/Core-2-Extreme/Video_player_for_3DS#Recommended-resolution) and [Benchmark](https://github.com/Core-2-Extreme/Video_player_for_3DS#Benchmark) for performance then use commandline in the [Prepare videos (advanced users)](https://github.com/Core-2-Extreme/Video_player_for_3DS#prepare-videos-advanced-users).

If not, you can use these tools (**these tools are third-party tools, therefore support for these tools are provided by their developers**):
* [Nintendo Video Convertor (by T0biasCZe)](https://gbatemp.net/threads/nintendo-video-convertor-video-convertor-for-3ds-and-wii.622972/)
* [VideoPlayer3DS DS Assistant (by JustScratchCoder)](https://github.com/JustScratchCoder/VideoPlayer3DS-DS-Assistant)

## Prepare videos (advanced users)
*If you are not familiar with CUI tools, you should use third-party tools above or consult friends, family, DeepSeek, ChatGPT and/or DuckDuckGo for how to use ffmpeg.*
1. Prepare your original videos.
2. Download [ffmpeg](https://ffmpeg.org/download.html) if you don't have it.
  * If you are looking forward to making non-3D videos...
    * Use `ffmpeg -i {input_file_name} -c:a {audio_codec} -c:v {video_codec} -s {resolution} {q} {output_file_name}`
  * If you are looking forward to making 3D videos...
    * That is SBS (side-by-side) (**recommended**)...
      * Use `ffmpeg -i {input_file_name} -c:a {audio_codec} -c:v {video_codec} -s {resolution} {q} -metadata:s:v:0 stereo_mode={sbs_type} {output_file_name}`
    * That is non-SBS...
      * Referer this: [How to convert your 3D video for 3DS (by T0biasCZe)](https://gbatemp.net/threads/release-video-player-for-3ds.586094/page-10#post-9575227)
3. Copy generated videos to your 3DS (anywhere on your SD card).

Where:
* `{input_file_name}` is your original video (e.g. `my_movie.mp4`, `camera_1990_01_01.avi` etc..).
* `{output_file_name}` is a converted file that is ready to play on your 3DS (e.g. `my_movie_converted.mkv`, `for_3ds.mp4` etc..).
  * For most cases, `.mkv` is recommended because it uses less RAM when playing it (hence less chance of out of memory error).
* `{audio_codec}` is an audio format (e.g. `aac`, `mp3`, `libvorbis`, `libopus` etc..).
  * If you don't know what it is, use `aac` for `.mp4` and `libvorbis` for `.mkv`.
* `{video_codec}` is a video format (e.g. `mpeg2video`, `mpeg4`, `libx264`, `libx265` etc..).
  * For **OLD**3DS/2DS, `mpeg4` is recommended.
  * For **NEW**3DS/2DS, `libx264` is recommended.
  * If you don't know what it is, use the recommended value above.
* `{resolution}` is a resolution of video frames.
  * For **OLD**3DS/2DS, `400x240` is recommended.
  * For **NEW**3DS/2DS, `800x240` or `800x480` is recommended.
  * If you don't know what it is, use the recommended value above.
* `{q}` is a quality of your video, lower value gives higher quality (and usually larger file size).
  * Use `-crf {number}` for `libx264` and `libx265`.
    * Something around `25` is a good point to start.
      * Adjust it according to your preference.
  * Use `-q:v {number}` for `mpeg2video` and `mpeg4`.
    * Something around `8` is a good point to start.
      * Adjust it according to your preference.
* `{sbs_type}` is a stereoscopic metadata (used to know how images are aligned).
  * Note: You should use `.mkv` for `{output_file_name}` because some containers such as `.mp4` doesn't keep this metadata.
    * If your SBS video has left:right alignment (most common) (that is, **left picture** is for **left eye**, **right picture** is for **right eye**), use `left_right`.
    * If your SBS video has right:left alignment (that is, **left picture** is for **right eye**, **right picture** is for **left eye**), use `right_left`.
    * If your SBS video has top:bottom alignment (that is, **top picture** is for **left eye**, **bottom picture** is for **right eye**), use `top_bottom`.
    * If your SBS video has bottom:top alignment (that is, **top picture** is for **right eye**, **bottom picture** is for **left eye**), use `bottom_top`.

E.g.:
* "I want to convert my video that is called "GNU.mp4" for my **OLD**3DS."
  * `ffmpeg -i "GNU.mp4" -c:a libvorbis -c:v mpeg4 -s 400x240 -q:v 8 GNU_for_3DS.mkv`
* "I want to convert my video that is called "GNU.mkv" for my **NEW**3DS."
  * `ffmpeg -i "GNU.mkv" -c:a libvorbis -c:v libx264 -s 800x240 -crf 25 GNU_for_3DS.mkv`
* "I want to convert my video that is called "GNU.mkv" for my **NEW**3DS, **I don't care file size** and want to make it as **high quality** as possible."
  * `ffmpeg -i "GNU.mkv" -c:a libvorbis -c:v libx264 -s 800x480 -crf 0 GNU_for_3DS.mkv`
* "I want to convert my **left:right SBS** video that is called "GNU_in_SBS.mp4" for my **OLD**3DS."
  * `ffmpeg -i "GNU_in_SBS.mp4" -c:a libvorbis -c:v mpeg4 -s 400x240 -q:v 8 -metadata:s:v:0 stereo_mode=left_right GNU_in_SBS_for_3DS.mkv`
* "I want to convert my **bottom:top SBS** video that is called "GNU_in_SBS.mp4" for my **OLD**3DS, **I don't care video quality** just make it **smaller**."
  * `ffmpeg -i "GNU_in_SBS.mp4" -c:a libvorbis -c:v mpeg4 -s 400x240 -q:v 40 -metadata:s:v:0 stereo_mode=bottom_top GNU_in_SBS_for_3DS.mkv`
* "I want to convert my **left:right SBS** video that is called "GNU_in_SBS.mp4" for my **NEW**3DS."
  * `ffmpeg -i "GNU_in_SBS.mp4" -c:a libvorbis -c:v libx264 -s 800x240 -crf 25 -metadata:s:v:0 stereo_mode=left_right GNU_in_SBS_for_3DS.mkv`

Prp tip: If you find you frequently see "Processing video..." message during playback, try lowering `{resolution}` and/or \
framerate by adding `-r {fps}` (e.g. `ffmpeg -i "GNU.mp4" -c:a libvorbis -c:v mpeg4 -s 256x144 -q:v 8 -r 23.976 GNU_for_3DS.mkv` for `256x144@23.976fps`).

## Recommended resolution
Videos that in this resolution will be played without any problems in most of the situations.
|  Recommended resolution  | mpeg1video | mpeg2video |    H263+   |    H264    |    H265    |
| ------------------------ | ---------- | ---------- | ---------- | ---------- | ---------- |
| OLD3DS Software decoding | 400x240@30 | 400x240@30 | 400x240@24 | 256x144@24 | 256x144@10 |
| NEW3DS Software decoding | 800x240@30 | 800x240@30 | 800x240@30 | 800x240@30 | 800x240@20 |
| NEW3DS Hardware decoding |    none    |    none    |    none    | 800x240@60 |    none    |

Videos that in this resolution may be played without problems if scene changes, camera panning etc.. are infrequent.
|    Maximum resolution    | mpeg1video | mpeg2video |    H263+   |    H264    |    H265    |
| ------------------------ | ---------- | ---------- | ---------- | ---------- | ---------- |
| OLD3DS Software decoding | 800x240@24 | 800x240@24 | 800x240@20 | 400x240@15 | 256x144@20 |
| NEW3DS Software decoding | 800x480@30 | 800x480@30 | 800x480@30 | 800x480@24 | 800x240@30 |
| NEW3DS Hardware decoding |    none    |    none    |    none    |1280x720@20 |    none    |

**Note: Video resolution that exceeds screen resolution (400x240 on OLD2DS, 800x240 on OLD3DS, NEW2DS and NEW3DS) has little visible effect.**
