Download a video
Download only what you have the right to use. Files stay on BasePic for one hour.
How it works
- Upload the AVI
Tap Upload video and pick the AVI, up to 2 GB.
- Wait for the preview
Browsers don’t play AVI, so BasePic first makes a preview copy for the editor. For a long video this takes a little while.
- Convert
Tap Convert to MP4. The MP4 gets its own link and a Download button; your AVI stays as it was.
DivX, Xvid and Motion JPEG
AVI files from cameras and from the DivX and Xvid days hold MPEG-4 Part 2, Motion JPEG or DV video, which browsers and phones don’t play. BasePic re-encodes them to H.264 at good quality, with the same size in pixels. An AVI with H.264 video is copied without re-encoding.
Sound
The sound becomes AAC, which every phone and browser plays. MP3 sound stays MP3 only when an H.264 AVI is copied.
How long the video can be
Re-encoding works on videos up to 15 minutes long at 1080p or 4K, up to 33 minutes at 720p, 1 hour 15 minutes at 480p and 2 hours at 360p or smaller. For a longer video, trim it and convert it in parts.
Your link and your original
The MP4 is a new file with a Short link and a Long link, ready to share or download. The AVI you uploaded keeps its own link.
AVI to MP4: questions
How do I convert AVI to MP4?
Upload the AVI, wait for the preview and tap Convert to MP4. The MP4 gets its own link and a Download button.
Will the quality change?
It is re-encoded once to H.264 at good quality, with the same size in pixels. An AVI with H.264 video is copied as it is.
Why can’t I watch the AVI in my browser?
Browsers don’t play AVI. The MP4 plays in every browser and on phones.
How long can the video be?
Up to 2 GB. When it is re-encoded, up to 15 minutes at 1080p, 33 minutes at 720p, 1 hour 15 minutes at 480p and 2 hours at 360p — trim a longer one first.
Is it free?
Yes. No sign-up and no watermark.
