(This article was originally published on April 2, 2018.) The next release of learningBOX is expected to include the ability to upload SCORM materials. First, we plan to support SCORM 1.2 packages for single SCOs. In the future, we plan to advance support for newer SCORM versions and to support registration of courses consisting of multiple SCOs.

問題を作成する方法は３つありますが、人によって好みの方法があります QuizGeneratorで問題を作成する際、人によってやりやすい方法、やりにくい方法があります。 ・問題作成フォームで作成する ・テキストファイルで作成する ・エクセルファイルで作成する 上記３種類で作成する方法がありますが、私、個人的にはテキストと表計算ソフトでの作成の方が楽だと思っています。人によっては逆に問題作成フォームの方が簡単でいいと思っている人ももちろんいらっしゃいます。 どの作り方でも順番は異なりますが、やっていることは他の作成方法と変わりません。 1. 問題文を入力 2. 問題種別を選択 3. 解答を用意する 基本は全てこれだけです。問題種別によっては3が少し変わりますがこれさえ押さえておけば、紙で作るテストと同じ感覚で大丈夫です。   とりあえずテキストで問題を作成 とにかく一度問題を作ってみましょう。それが一番分かりやすい覚え方です。昔から言われている書いて覚えると同じです。とにかく手を動かしてみます。 今回作成する問題は以下の３つです。 5×5＝？ (選択肢の中から正解を選ぶ) 日本で一番大きい都道府県を書け (実際に入力させる) 日本で一番大きい都道府県を書け 数字と漢数字を正しく組み合わせよ (正しい組み合わせを作る) テキストファイルを保存できるエディタを起動します。メモ帳、テキストエディット、秀丸、Atom、なんでも構いません。   まずは一番簡単な物から作成します。 5×5＝？ (選択肢の中から正解を選ぶ) これを作っていきます。 1. 問題文を入力します。 5×5＝？ 2. 問題種別を入力します。 5×5＝？ sa: 3. 正解を入力します。 5×5＝？ sa: 25 4. 他の選択肢を入力します。今回は３つの選択肢です。 5×5＝？ sa: 25 5 10 1 これで一問完成です。   残りの問題も同じように書いていきます。 まずは記述式の問題は下記の通りに書きます。 日本で一番大きい都道府県を書け fill-in: 北海道 ユーザーが回答時は、「北海道」と入力することで正解となります。最初に作った四択問題よりも書くことは少ないですね。   最後に組み合わせ問題です 組み合わせ問題は下記の通りに書きます。 数字と漢数字を正しく組み合わせよ。 match: １::一 ２::二 ３::三 ４::四 ユーザーは回答時に、右側に入力した漢数字をドラッグ＆ドロップで左側の数字に合うように組み合わせることで正解になります。   ３つの問題をまとめます これで３つの問題がそれぞれ完成しました。 テキストファイルで作成時は、最後にこれら３つの問題をまとめます。 5×5＝？ sa: 25 5 10 1 日本で一番大きい都道府県を書け fill-in: 北海道 数字と漢数字を正しく組み合わせよ match: １::一 ２::二 ３::三 ４::四 問題ごとの区切りとして空行を挟みます。空行はいくら挟んでいて構いません。 入力を終えれば保存します。これでテキストファイルで作成するのは完了です。   とりあえず表計算ソフトで問題を作成します。 今度は表計算ソフトで問題を作成します。 とにかく一度問題を作りましょう。それが(以下略)。 今回作成する問題は以下の３つです。 5×5＝？ (選択肢の中から正解を選ぶ) 日本で一番大きい都道府県を書け (実際に入力させる) 数字と漢数字を正しく組み合わせよ (正しい組み合わせを作る) 表計算ソフトを開きます。ExcelやGoogleスプレッドシートなどを開きます。 テキストとは異なり、セル1Aに必ず「#format:table」を入力します。 この「#format:table」が表計算ソフトで作っていますという証明になります。 問題は2Aから入力していきます。 表計算ソフトではA列に問題文、B列に問題種別、C列に正答、D列以降に誤答などを入力していきます。 残りの2問も入力します。 #format:table 5×5＝？ sa: 25 5 10 1 日本で一番大きい都道府県を書け fill-in: 北海道 数字と漢数字を正しく組み合わせよ match: 1::一 2::二 3::三 4::四 入力を終えれば保存します。保存の際、ファイル形式は「.xlsx」で問題ありません。   作成した問題をクイズプレイヤーに変換する 作成した問題をクイズプレイヤーに変換します。   QuizGeneratorの場合 ヘッダーメニュー内にある「変換ツール」をクリックします。 作成した問題ファイルをアップロードして変換します。 変換が成功すると、下記画像のようにクイズをどうするかの選択肢が表示されます。 ▼各選択肢について プレビュー：別タブでアップロードした問題の確認ができます。 ダウンロード：ホームページに乗せたりするために必要なファイルがダウンロードできます。 限定公開：URLを知っている人にのみ問題を公開することが出来ます。また、ifreamも表示されますので、こちらでもホームページなどに埋め込むことが出来ます。 一般公開：lm.QuizGeneratorの一般公開ページに掲載されます。 （現在、変換ツールによる一般公開はサービス終了しました。クイズの一般公開をご希望の方は、問題作成フォームをご活用ください。）   learningBOXの場合 まずlearningBOXにオーナー登録をします。10アカウントまでは期間無制限で無料でご利用頂けます。 コンテンツ管理から＋マークをクリックして。クイズ　>　クイズ・テストをアップロード をクリックします。 作成した問題ファイルをアップロードして保存します。 登録に成功すると下記の画像のようにコンテンツ管理内に配置されます。   とりあえず問題作成をしてみた 作成してみて分かって貰えたと思うが、入力の法則と問題種別さえ覚えているとテキストや表計算ソフトの方が速く作ることが出来ます。さらに付け加えると、問題数が多い場合、問題作成フォームだと途中で保存もできず、エラーが発生した場合、一から作成する必要があります。 10問位なら仕方ないと諦められます。20問程度なら面倒だけどやるしかないと諦められます。50問ならその日のやる気を根こそぎ奪われるでしょう。100問になると二度と見たくないと思うでしょう。 途中で保存出来るのは本当に便利です。本当に便利です。  

LearningBOX allows you to upload 500MB of video per video if you subscribe to a high-capacity video plan. As stated in the section on video capacity, even a 1 or 2 hour video can be kept within the 500MB limit with proper compression. However, it is troublesome to purchase video editing software and set up compression settings just to reduce video capacity. Therefore, we had published a video compression procedure using FFMPEG. Once set up, it is convenient and easy to compress many videos, but FFMPEG has some quirks in its installation, and we think there were some cases where users were stumped by the settings. This time, we have developed an easier way to compress videos, and we would like to introduce it to you. (Works on Windows 7 or later) Encoder_20200630.zip Procedure Download and unzip the Encoder_20200630.zip file above. Double-click Encoder.exe to launch it. Select the image quality if necessary. The "640 width standard plan" is the setting that produces the smallest video size. This is the recommended setting if you have not subscribed to any video options. Width 1280 Large Video Plan" is the setting suitable for large video plans. If the video size exceeds 500 MB with this setting, you can reduce the size by using the 640 setting. No Size Change" is a setting where the video is re-encoded without changing the video size. Although the video size is not changed, the capacity can be reduced in many cases. Drag and drop video files into the above window to start encoding. If multiple videos are dragged and dropped together, the dragged and dropped videos will be encoded one after another. The encoded files will be saved in the same folder as the original videos with a file name such as ".640.mp4" appended to the end. FAQ Can Tatsuno Information System develop encoders? No, we cannot; we only provide an open source video encoder called FFMPEG for your convenience. Why does this method reduce the capacity? The capacity is reduced by adjusting the quality to a level suitable for e-learning. Specifically, we make the following adjustments Reduce the quality of the video In addition to adjusting the video size, we also adjust the compression ratio. Although it may not look as good as terrestrial digital or Blu-ray, the settings are sufficient for educational videos. Reducing the frame rate of the video Video at 60 frames per second is smooth. But do you need 60 frames per second for video of a board or instructor? By keeping the video at 30 frames per second, we reduce the amount of space required. Making the audio monaural By making the audio monaural, the amount of audio data is reduced by half. Use an appropriate codec Compression with h264 reduces the capacity of the video. Fine-tune the image quality This article is intended to be "simple" and does not provide detailed settings for image quality. Please use ffmpeg on the command line or use "Drag and Drop Video Encoding" to rewrite parameters for encoding. If your goal is to put the video on learningBOX, our LMS, we will support you in setting up the video. Update History 2018.4.1 First version released 2018.4.2 Fixed bug version released -- improved handling of video filenames with spaces in them

Apology and Cause The problem occurred from about 20:00 on 2/27/2018 to 19:00 on 2/28/2018. We apologize for any inconvenience this may have caused to our users. The cause of the problem is that we use the mail server SES provided by AMAZON, and due to a case of violation of the SES usage policy, a temporary suspension measure was taken. The reason for the violation was that a large number of batch registrations of users with nonexistent e-mail addresses occurred, resulting in an extremely high percentage of bounce mails (error mails), and AMAZON received a warning from AMAZON. As a temporary measure, we have notified the affected users not to use the e-mail invitation function. As a countermeasure in the system function, we are planning to change the current requirement of an e-mail address to allow users to register their e-mail address on a voluntary basis. We apologize for any inconvenience this may cause. We hope you will continue to use our system as usual. About the list that could not be sent The list of users to whom emails could not be sent is stored in our database and will be provided as an Excel list for each user. Currently, there are five possible cases where an e-mail could not be sent. If you have already been invited to become a member, but have not yet used the service. Step 1. Delete the member. If the member has not yet used the system, you can delete the member from the environment. If the member has not yet used the system, you can delete the member from the environment. Click on the member's name on the "Add/Edit Member" page, and then delete the member. Step 2 Add the member again After deleting the member, please re-add the deleted member. The invitation e-mail will be sent as usual. If you have already invited a member and the member has already started using the service You can use the same ID/PASS as before. You have been notified of your ID/PASS separately. You can use your ID/PASS as it is. In the case of sending a message Countermeasure Case 1 Send a confirmation request. The message is still in the system, so please send us a message asking us to log in and confirm the message, or send us the same message again. Countermeasure Case 2 Send a separate email requesting confirmation of the message. Please send a confirmation request e-mail "Please confirm your message" by another means (e-mail software), not in the system. In case of password reset If the message is not received, etc., ask the user to perform the password reset operation again. In the case of password reset, if the user is unable to reset the password and In the case of a password reset, the user may not be able to reset his/her password, and we or the administrator may have been contacted in some way. If you receive an inquiry, please let us know that there was a problem with the system on the operator's side and that you are already able to use the system. In case of login authentication Please contact us to let us know that the system has been restored. Please use the message function, etc., to inform all system users that the login function has been restored.

Nishimura. This week, we have been receiving an increasing number of video materials for registration on learningBOX. As a result, video encoding has been delayed for some time, which has been causing some inconvenience to our customers. Today, we have increased the number of video encoding servers to improve processing speed and optimize the video processing order. We will continue to develop this service so that you can use it as comfortably as possible.

Videos shot with action cameras and drive recorders are sometimes split into 3- or 5-minute segmented files. It is a hassle to use expensive editing software or manually adjust the video just to merge the broken pieces. We'd like to make the process of merging videos much easier! With FFMPEG, you can merge videos with a single command, but if you have many files to merge, it is troublesome to write commands. So, I created a batch file that allows you to merge videos by simply dragging and dropping them. Operation Procedure Drag around the files to be combined. At this time, select from the last video to the first video. Then, drag and drop the files together into ffmpeg-concat.bat to start the batch. When the batch is launched, a list of files to be combined will be displayed, and if all is well, press any key to start combining. Batch download https://quizgenerator.net/wp-content/uploads/bat/ffmpeg-concat.bat Source Code @echo off set FILES= set N=0 REPEAT set /a N=N+1 set FILES=%FILES% -i %1 if "%~2"==""" GOTO EXIT GOTO EXIT GOTO REPEAT EXIT echo %FILES% pause ffmpeg %FILES% -filter_complex "concat=n=%N%:v=1:a=1" %1.merged.mp4 pause Summary. Let's make it easy by drawing a batch!

I want to make a manual video. We would like to add still images to the video and arrange it. I want to add explanatory text to make the video easier to understand. But video editing seems difficult. In such cases, you can easily create a video using iMovie on your iPhone. This time, we will create an instructional video using video and still images. We will use the video below as material for the explanation. Preparation Video for editing Screenshots of the parts of the video that you want the audience to view in more detail How to take a screenshot: 1. While holding down the iPhone sleep/wake button (power button), press the home button. When you hear a "click" sound and the screen blinks white, the picture has been taken successfully. Save the photo. Editing Use iMovie as a free video editing software. 1) Launch iMovie and tap "Create Project". (2) Next, select "Movie". (iii) Check the movie you wish to edit and tap "Create Movie" to insert the movie. (3) Tap the video "by aligning the white vertical line with the area where you want to insert a still image". Then the operation toolbar will appear at the bottom of the screen. Tap the "Split" button. Next, the image will be split and the image will be inserted in the split area. Tap the "+" button on the left side of the screen, and select the image you wish to insert from among the photos. At this point, the preparations are complete. Now it is time to add text to the inserted image. Tap the inserted image and tap "T". A list of text styles will be displayed. In this case, "Standard" will be used. Tap "Standard" and then tap "Enter Title" on the image to enter the text. In the case of "Standard," three large and three small titles are displayed, and you can delete any title you do not need. You can also choose to place the text in the "center" or "bottom" of the screen, so choose your preferred placement. After that, press the "Done" button in the upper left corner of the screen to complete the editing. The following is a video that has actually been edited and edited. There are various other functions that can be combined to create original edits.

I have installed FFmpeg, but there are so many option settings that I don't know how to set them. I know the settings, but it is tedious to encode one file at a time with commands. In such cases, it is convenient to create a batch file like the one below to encode video files by simply dragging and dropping them. *You must use a "Windows PC" to use this batch. You also need to have ffmpeg on your execution path according to the video compression (FFmpeg Setup and Encoding Instructions). You can encode videos by simply dragging them into the .bat file as shown below. You can drag multiple files together. The encoded file name will be automatically set according to the original file name. Batch files for encoding The second and third batch files are excellent for resizing, but depending on the aspect ratio of the original video, the height may be odd and cannot be encoded. Reduce the size without changing the size (↓click to download) https://quizgenerator.net/wp-content/uploads/bat/ffmpeg-noresize.bat Reduce the capacity to the standard quality of learningBOX - width 640 (same as above) https://quizgenerator.net/wp-content/uploads/bat/ffmpeg-640.bat Reduce capacity to learningBOX's high quality video plan - width 1280 (same as above) https://quizgenerator.net/wp-content/uploads/bat/ffmpeg-1280.bat Batch file description The following code is from ffmpeg-1280.bat. -vf scale=1280:-2 * Specifies the size of the image. The width is 1280 and the height is automatic. If -2 is specified, it is adjusted to be a multiple of 2. -crf 22 * Image quality setting. The larger the value, the poorer the image quality (and the smaller the capacity). -r 30 * Specifies the frame rate. The larger the value, the smoother the video (more space is required). -ac 1 * Specifies monaural audio. If you want monaural audio, specify this value to reduce the size. ECHO OFF REPEAT ffmpeg.exe -i %1 -vcodec libx264 -vf scale=1280:-2 -crf 22 -r 30 -y -ac 1 "%~n1.w1280.mp4" if "%~2"=="" GOTO EXIT GOTO EXIT GOTO REPEAT EXIT GOTO REPEAT :EXIT Revision History 2018.1.19 First version released 2018.4.2 Changed height specification from -1 to -2 / changed to -2 because it sometimes caused an error depending on the video size
