Help! Can't convert .mov files to mp4

Postby Matthew Max » Fri Sep 08, 2023 5:19 pm

Hey, everybody or somebody, I received some .mov files from a client who wants me to make an mp4 movie with them. He shoots the video files on his iPhone 12. He sends them to me from Europe and via Dropbox. It seems that Dropbox does alter the files. This doesn't happen when we use Drive.

It used to be easy to run a conversion program on my phone and make his files workable on my fine Windows equipment. Any equipment of mine, any program. But this time, I cannot get his files to work. They look fine on my phone, and when I try to move them to my computer, they're only audio.

I don't think the community has ever failed to solve my problems. Let's do this one more time.

EDIT: Well, we tried Drive and nothing changed. Can iPhone cameras be re-installed or whatever? I think this is the second iPhone of his that has been doing this.

Thanks.

Max

Would need to see a screenshot of the file properties to diagnose. Offhand I would say the the likely culprit is one of the following:

1. A PAL file format
2. An HEVC format file
3. Variable frame rate (Like Peru said)

But it is very difficult to pinpoint with out seeing the properties.

Please use the free MediaInfo and post a screenshot of the properties of your media in tree view:

Many users are having issues with VFR. If the file is variable frame rate, use Handbrake to convert to constant frame rate:

Here is a tutorial:

Shutter Encoder may also be used to convert to Constant Frame Rate:

+1 for conversion using Handbrake.

I would be surprised if the culprit was PAL encoding but then, at my age, I am often surprised. :fg:

Hey, thanks for all the information, guys, because I will use it in the future. This time, it turns out that my client needed to update his devices.

What a relief!

By the way, I wasn't getting notifications of your replies. Any idea how I can check to see if something changed? I don't see any changes in my settings.

On the page where you post messages, right under the section where you compose the message is an Options tab. Make sure that "Notify me when a reply is posted" is checked. It's sticky, and remembers your choice the last time you posted. Another possibility: You've changed your email address without changing it in your User Profile account settings?

Hmm, well, I checked my email and it's the same. And the notifications box is still checked. I hate to miss replies to my calls for help, after my friends take the time to help me. the only reason I saw this reply is because I wondered if I hadn't received a notification, which I did not.

I had a problem with my husband's old iPhone not transferring full rez files. I read online that iPhone with downsize on output unless changed in settings. Not sure if that is your specific problem. To transfer files I used WeTransfer. It is a free service.
