How to use this tool

  1. 1

    Pick the MOV clips

    Upload up to 20 .mov files of 95 MB or less each. A minute of 4K iPhone video is typically larger, so trim it on the phone first.

  2. 2

    Use the player profile

    Resolution 480p, Frame rate 30 fps and Audio codec MP3 at 128 kbps match what DivX-era players decode. Choose 720p if the TV's manual lists HD AVI.

  3. 3

    Convert and test one

    Press Convert to AVI, copy one file to the stick and try it on the device before converting a whole holiday. Uploads are deleted after 30 minutes.

iPhone MOV clips on a TV that only reads AVI

Apple's QuickTime format dates from 1991, but the MOV files people struggle with today come from iPhones: HEVC video since iOS 11, Dolby Vision HDR on iPhone 12 and later, and often 60 fps. Each of those is a feature an older TV's chip cannot decode, so the screen shows an error or a blank thumbnail.

AVI with MPEG-4 Part 2 video is the lowest common denominator for that hardware. The preset converts down to it on purpose: standard definition, a constant frame rate and MP3 sound. If the device also lists MP4 in its manual, an MP4 is the better choice, and MP4 to AVI covers clips that already left the phone as MP4.

MOV

QuickTime movie

MOV is the QuickTime container format created by Apple in 1991. iPhones record MOV files, and professional editing tools use it for high-quality codecs such as Apple ProRes, including versions with transparency. It can hold multiple video, audio, timecode and subtitle tracks. MOV files from editing software can be very large, and some Windows apps, Android phones and websites play them poorly or not at all.

AVI

Audio Video Interleave

AVI is a multimedia container introduced by Microsoft in 1992 as part of Video for Windows. It can hold many codecs, from uncompressed video to DivX and Xvid, which made it a common format for camcorders and downloaded films in the 2000s. It lacks modern features such as reliable variable frame rates and standard subtitle support, and files are often large. Desktop players such as VLC play AVI, but phones and browsers usually cannot.

MOV goes to AVI when a phone video has to play on hardware from before HEVC: the player understands DivX-style AVI from a USB stick and nothing Apple has recorded in years.

MOV to AVI playback problems and fixes

  • The player lists the file but says the format is unsupported

    Lower Resolution to 480p if you changed it, and confirm the manual mentions DivX or Xvid. Some players read AVI only with these codecs.

  • Colors look dull or grey compared with the phone

    The clip was recorded in HDR, which AVI cannot signal. Turn off HDR Video under Settings > Camera > Record Video for clips meant for old screens.

  • Sound slowly drifts away from the picture

    Keep Frame rate at 30 fps; variable-rate phone video converted at its source rate can drift on players with weak clocks.

  • The file name shows as garbled characters

    Rename files with plain letters and numbers before copying. Many older players cannot render emoji or accents.

Sound settings for an AVI from a phone video

iPhones record AAC sound, which many DivX-certified players cannot decode inside AVI, so the preset switches to MP3 at 128 kbps. That is plenty for voices and room sound from a phone microphone; raise Audio bitrate to 192 kbps for a concert clip. Want only the soundtrack? Our guide on how to convert MP4 to MP3 works for MOV files too.

MOV to AVI questions

Why does my TV show iPhone videos as unsupported but plays old AVI movies?

Since iOS 11 the Camera app records in HEVC when Formats is set to High Efficiency, and TVs from before roughly 2016 have no HEVC decoder. They also may not open the QuickTime container at all, while AVI with DivX-style video is exactly what their firmware was certified for.

Why is the frame rate fixed at 30 fps here?

iPhones can record at 60 fps and adjust the rate slightly during a clip. DivX player profiles top out at 30 fps for standard definition, so a constant 30 fps avoids stutter and audio drift on that hardware.

Will the vertical iPhone video fill the TV screen?

No. A portrait clip keeps its shape, so a 16:9 TV shows it as a narrow strip with black bars on both sides. Film sideways in landscape when the video is meant for a TV.

What happens to the location and date stored in the MOV?

The MOV keeps creation date, GPS position and camera model in QuickTime metadata. AVI has no equivalent fields, so the converted file only carries a new file date; keep the original if you sort videos by place.

Can I record iPhone videos that skip this step?

Partly. Settings > Camera > Formats > Most Compatible records H.264 instead of HEVC, which more old TVs accept inside an MP4 or MOV. Players that only read AVI still need the conversion.

Is MOV to AVI lossless?

No, the clip is re-encoded and, at the 480p default, scaled down. On a TV across the room the difference from the original is small; for editing or archiving keep the MOV, or use the MOV to MP4 converter for a modern copy.
