# First render {% @arcade/embed flowId="4PdYiDI6W5JywsGB5kOi" url="" %} *** Now that we have completed the animation, it's time to put our video to the test by rendering it. During the rendering process, it's important to keep in mind that it may need to be done multiple times. It may require careful adjustments and iterations to achieve the best possible outcome. First, we choose the composition(s) we want to render. We can select one or multiple compositions. Then, we simply click on the render button. {% hint style="info" %} Compositions names are transformed into scene names on all platforms, so having a well-organized naming system can be really beneficial in the long run. {% endhint %} After clicking render, the extension will convert the selected comps into a simple but complex Mp5 file. It will then automatically upload the file to Blings Studio, along with the necessary fonts, video files, sounds, and images. All of these elements will be uploaded and converted automatically to ensure compatibility and optimization. ## Alerts and Errors Since not all After Effects features work, the extension will give you an alert when theres things we need to tweak before rendering. You can check the full compatibility list [here](https://www.notion.so/MP5-Compatible-Features-in-After-Effects-022cd9d89d7b4ef09661b3bbb51310f7?pvs=21).
AlertDescription
This type of alerts are for stuff that would just make it really hard and not fun for you. So we block you from rendering.
This type of alerts are for stuff that we’re good with, but we have to keep in mind those stuff might be tricky.

Collapse transform switch

The collapse transform properties wont be visible in the final render, so to avoid any unwanted outcome we ask to avoid using it.

WAV audio files

Wav files are simply not supported.

Audio layers should not be In negative offset

To render properly the sound we need to make sure audio layer don’t exceed out work area. Trimming the layers on both sides fixes it.

Text Deform

Text deform properties wont be visible. To avoid any unwanted outcome we ask to avoid using it.

Mp4 layer should always be on the bottom of the layer stack in the composition
Looks like we have some heavy files
The extension starts the render process with summing up the weight of all the files related to that export, using heavy files may increase the loading time of the video when there’s low internet connection, So we let you know that and give you the option to choose.
*** ## FAQ
How long does the rendering process usually take? The rendering time can vary based on the complexity of your compositions and the performance of your system.
Can I cancel or pause the rendering process? You can cancel the render process by clicking the cancel button. Pausing is not possible.
What should I do if I encounter an error during rendering? Ensure that your computer has a stable internet connection.
