Editing

What kind of videos can be uploaded?

We generally support the majority of video formats that are commonly used. You can check the detailed codec types at Amazon transcoder introduction slide.

What format will the rendered video be in?

The video is added as an mp4 file in h264 format, and the frame rate is 30fps.

Can I reduce the size of the downloaded video?

The rendered video is already compressed. However, we have proceeded with a level of compression that maintains reasonable quality, so in cases with a lot of content, the size can become quite large. In such cases, you can use external compression tools to further reduce the size significantly (at the cost of some quality). If you search for 'online video compressor' on Google, you can find various free compression tools to try. Please click the link below!

Are there no mosaic features?

In the current engine format, when giving a mosaic effect, it is possible; however, if the animation elements increase, a phenomenon called frame drop occurs. Therefore, until another rendering engine implementation, the feature might be difficult to provide. We are aiming to offer it in the long term.

Are there any limitations on file upload and project additions?

VideoStew imposes certain limits on each project and upload size, as well as AI voice settings, to provide stable service. The standards for each are as follows:

  • Individual image upload size: 20MB
  • Individual video upload size: 250MB
  • Maximum length of a single AI voice text: 1,000 characters
  • Maximum length of the text input window: 5,000 characters or 150 sentences
  • Maximum project duration: 10 minutes (20 minutes for the premium plan)
  • Maximum number of slides within a project: 400 slides
  • Maximum number of elements within a slide: 100 elements

The shortcuts are not working

If shortcuts are not functioning, you can first suspect the browser's extensions. There is a high chance that it's related to a keyboard-involved extension. You can resolve the issue by exempting VideoStew (https://videostew.com) in the settings of the respective extension or by disabling the problematic extension. If you're not sure which extension is causing the issue, you should access [Window > Extensions] from the upper side menu and disable them one by one to find the problematic extension.

Can I upload videos/images I have?

Select the video or image from your computer and drag and drop it into the editing screen to add the image, which will be stored in the "User" tab.

Furthermore, when uploading multiple files at once, if you drag and drop them into the left side Library Window, they will not be added to the editing screen, but only to the library. If you are curious about how to upload directly from a mobile device, please refer to the [Mobile Device File Upload Guide](https://videostew.com/guide/tips/mobile-upload).

The narration doesn't read properly. Can I adjust it as I wish?

If the narration sounds strange, or if only the main words are shown and the actual content to be read is different, we recommend using the method of utilizing the external text area. ![](https://cdn.videostew.com/web/views/guide/edit-ai-voice.mp4?_=1im0nm1) Enter the text that will appear on the screen and click on [Read by AI Voice](/guide/edit/basic/text/enable-tts) option; outside the screen, enter the actual content to be read.

The narration pronunciation sounds strange

In the case of AI Voice, we use engines from third-party services (Google/Naver, etc.). Our experience shows that engines are often upgraded through learning, but sometimes errors occur when reading certain phrases strangely. When such cases are detected, we provide feedback to the service provider, but due to the characteristics of AI implementation, it is impossible to manually correct these errors. The improvement is done through relearning over time, and thus, processing may take longer. The best solution is to temporarily avoid the problematic pronunciation by modifying the text.

Narration skips and goes to the next slide

If AI Voice has not read all the text on one slide and moves on, it could be a temporary network error or a miscalculation of narration timing. In such cases, you can recalibrate the duration of the narration by clicking the [Narration > Recalculate Timing] button. ![](https://cdn.videostew.com/web/views/guide/tts-timing-recalcu.mp4?_=1i85mbd)

Can I manage frequently used elements separately?

You can easily manage all elements through [Favorites](/guide/edit/basic/bg-color/favorites). All elements of VideoStew, including videos, images, shapes, texts, colors, music, etc., can be added to the [Favorites](/guide/edit/basic/bg-color/favorites) tab for easy reuse. ![](https://cdn.videostew.com/web/views/guide/add-favorite2.mp4?_=1i106fc)

Can I display my uploaded image to fill the screen?

You can change the display method of the image by setting the 'Internal Display Mode'. By default, images that you have added yourself or copied from a website are entered with 'Original Proportion' as the 'Internal Display Mode'. You can change this setting to 'Fill Screen' and then use the handles to adjust to the desired size. Furthermore, when the 'Internal Display Mode' is set to 'Fill Screen' or 'Slowly Enlarge', you can easily fit the entire screen by using the 'Auto Fit' function on the right side panel. ![](https://cdn.videostew.com/web/views/guide/fill.mp4?_=1i1qq12)

What is the automatic slide division? (deprecated)

! The automatic slide division feature has been moved to the [Application Unit](/guide/edit/basic/text/text-animation/2ei266m) of text animation. Please refer to the text animation documentation for detailed information. In VideoStew, a slide signifies a single scene. It would be great if you could divide your text into units thinking of it as showing along with a background video. ![](https://cdn.videostew.com/web/views/guide/스크린샷_2023-05-03_오후_10.21.48.png?_=1i565bh) However, if a slide has too much text, you can use the [automatic slide division] feature to make it output in one or two lines for easier viewing. Because the sync of automatically generated text with the speech is taken care of, you don't have to worry too much; the subtitles will match the audio perfectly. But if the timing of a particular line doesn't match, you can manually adjust the sync of the subtitles.

My microphone's volume is not being recorded properly

First, please check if the waveform is properly visible when recording with the microphone. If the waveform isn't visible, you need to verify if the microphone permissions are properly set. ![](https://cdn.videostew.com/web/views/guide/스크린샷_2023-04-03_오후_12.27.17.png?_=1i2khvk) If you've allowed the microphone but keep getting a message to continue allowing it, you should check the input device settings in your operating system (such as Windows). If you are a Windows user, please refer to [this document](https://support.microsoft.com/ko-kr/windows/마이크를-설정하고-테스트하는-windows-ba9a4aab-35d1-12ee-5835-cccac7ee87a4).

Your video has been flagged for copyright infringement on YouTube

Most copyright claims on YouTube are due to music copyrights. To prevent this, you need to take action in advance by adding your YouTube channel URL to your workspace so that copyright infringement claims do not occur. You can check the detailed method in the link below. https://videostew.com/guide/faq/edit/youtube-register For videos that have already been added, please re-upload them after entering your YouTube channel information, or notify us of each video's address individually so that we can manually process your request.

How can I add my YouTube channel?

After hovering over the desired workspace, go to Edit > YouTube Channel > Enter the address of the YouTube channel and confirm ![](https://cdn.videostew.com/web/views/guide/youtube-channel.mp4?_=6itl) You must add your YouTube channel address to receive proper music usage rights from VideoStew's BGM music exemption service 'SelbyMusic'.

The quality of the uploaded image/video is low

The images/videos displayed on the editing screen are shown in lower resolution/quality to facilitate efficient editing. When you download the actual image or video, it supports up to near-original quality (up to a maximum of 1080p standard). Therefore, you can ignore the low quality displayed during editing.

The quality of the rendered video is degraded

If the quality of a typically rendered video is degraded, the issue is not with the rendering itself, but rather with issues that have combined after rendering elsewhere. If there is no problem when checking the rendered video itself, you should examine the following issues. - If you have transferred the rendered video via a messenger like KakaoTalk, the messenger will compress it once more. Messengers generally compress videos to lower quality in order to optimize for network performance. In this case, you should set the quality to 'Original' or 'High' in the messenger settings before transferring, or you should directly upload the mp4 without going through the messenger. - If the quality is too poor when viewed on YouTube, you should check the speed of your network. YouTube may automatically stream a lower quality version if the user's network is slow. You can forcibly change the quality to a higher setting in the YouTube player, or try checking the quality by opening it where a stable network is ensured.

Clicking download does not download the file

![](https://cdn.videostew.com/web/views/guide/스크린샷_2023-11-27_오후_3.19.06.png?_=1im8d83) Extensions in the Chrome browser may cause the download button to not work properly. In this case, you can go to 'Home > Environment Settings > General' and change the download method to 'Classic mode' and then try again. VideoStew generally provides support for standard mp4 video files. It is not possible to embed links in these standard videos. Links on videos from platforms like YouTube or TikTok are added by uploading options provided by the platform, and link overlays are added to the video on the user's screen. In other words, depending on the platform, it is a feature provided by the platform, so when you upload the video rendered from VideoStew, please proceed according to the settings of the platform.
