Overview

Renderjuice can generate an MP4 video in addition to your frame outputs. You can enable MP4 before a render starts or create one from a completed render. Your frame sequence is always preserved and remains the source of truth for re-renders. MP4 conversion is free and does not use any additional GPU-minute credits. The MP4 output that Renderjuice encodes is set to be visually lossless.

​
Blender video output vs Renderjuice MP4

If your Blender file is set to render directly to a video container (like FFmpeg), Renderjuice will not use that as the primary output. We render an image sequence and then generate MP4 as an additional output.

​
MP4 requirements (PNG/JPEG only)

MP4 is only available when Output Format is PNG or JPEG. A completed render needs at least two camera frames that are still available. If you select OpenEXR or OpenEXR Multilayer, MP4 is disabled. Renderjuice will still render and preserve your EXR frames, but it will not generate an MP4 in that configuration. If you need additional outputs (including videos) from EXR renders, you’ll need to use a third-party encoder.

​
What you’ll see in the post-validation config

If your render isn’t already configured for PNG/JPEG frames, enabling Video (MP4) may update fields like Output Format so frames are preserved (and you’ll receive an MP4 as well). For Blender 5+ files set to Video output, Renderjuice renders using Image output so frames are preserved, even if the read-only Blender Output Mode still reflects the file’s original setting.

​
Create MP4 after a render completes

  1. Open a completed render and select Outputs.
  2. Find Video from frames.
  3. Check the Video playback frame rate. Select Edit if you want to change the FPS or Base.
  4. Select Convert frames to MP4.
Renderjuice converts the frames in the background. You can leave the page while the conversion runs. Return to Outputs and select Download MP4 when it is ready. If an MP4 already exists, change the playback frame rate to create a new version without rendering the scene again.

​
Enable MP4 before a render starts

  1. Open a render in the app.
  2. In Editable render configuration, open Additional Outputs.
  3. Set Video (MP4) to Enabled.
  4. Double check any changed configuration fields still look correct.
Renderjuice creates the MP4 after the frame render finishes.

​
Download videos

When the video is ready, it appears in the render preview downloads list alongside your frame outputs. You can download the MP4 directly or copy links into a download manager.

​
Storage and expiration

The MP4 expires with the render’s other outputs. The render page shows the scheduled deletion date. File retention is 30 days by default, but your workspace may use a different period. Requesting an MP4 close to that date keeps the outputs available for at least 48 hours after the request. Renderjuice cannot encode an MP4 after the source frames have expired or been deleted. Download links are temporary. Reopen Outputs to get a fresh link while the files are still available.

​
Segmented videos (non-contiguous frames)

If your render uses non-contiguous frame ranges, Renderjuice generates multiple MP4s, one per segment. Each download is labeled with its frame range so you can grab only the pieces you need.

​
API note

Download responses include video URLs when a video is available. If no MP4 was generated, the video list is empty.
