Free online ODP to AVI converter

Some older media players and editing systems accept AVI but cannot open an ODP presentation. Converting the slides to video lets those systems play them, though the conversion method determines whether animations and audio are retained.

What the ODP format is

ODP (OpenDocument Presentation) is an open standard for slide presentations, commonly created with LibreOffice Impress or Apache OpenOffice Impress. It stores slides, text, graphics, and presentation effects; you may receive one when someone shares a presentation made in an open-source office suite.

What the AVI format is

AVI is a video container used by older Windows software, media players, and some editing workflows. It can hold different video and audio codecs, so an AVI file's compatibility depends on the codecs as well as the container. Choose it when the receiving device or application specifically requires AVI.

How to convert ODP to AVI

Online on 101convert.com

1. Open the ODP-to-AVI converter page and upload the presentation. You can add several files for batch conversion; each file is subject to the size limit shown on the page.
2. Set Show each page for to choose how long each slide appears, then start the conversion.
3. Download the resulting AVI file or files.

Offline with desktop software

Free workflow: LibreOffice, Poppler, and FFmpeg. This method works on Windows, macOS, and Linux where the three programs are installed. It renders slides as still images, so animations, transitions, and embedded audio are not included.

1. Export the ODP to PDF in LibreOffice Impress using File → Export As → Export as PDF, or run libreoffice --headless --convert-to pdf presentation.odp.
2. Render the PDF pages to PNG files with Poppler's pdftoppm -png -r 150 presentation.pdf slide. This creates files such as slide-1.png.
3. Use FFmpeg to make a video with each slide displayed for five seconds: ffmpeg -framerate 1/5 -start_number 1 -i slide-%d.png -c:v mpeg4 -q:v 5 -r 25 -pix_fmt yuv420p presentation.avi. Change 1/5 to set a different display duration.

Microsoft PowerPoint plus FFmpeg. PowerPoint can open ODP files on Windows and macOS. Open the presentation, use File → Export → Create a Video to export an MP4, then convert it with FFmpeg: ffmpeg -i presentation.mp4 -c:v mpeg4 -q:v 5 -c:a libmp3lame -q:a 4 presentation.avi. PowerPoint's video export can preserve timed playback and audio when configured; check the exported MP4 before converting it.

Quality and compatibility

AVI does not specify a single codec. The commands above use MPEG-4 Part 2 video; confirm that the target device supports that codec, because an AVI container alone does not guarantee playback. The LibreOffice image sequence produces silent video, and its slide duration is fixed unless you change the FFmpeg input frame rate.
