audio and video out of sync another question

Hello all,

I've read one other thread here about this issue, but mine is a little different.

I was having this problem with Photoshop Elements but because their system requirements are 8gb of ram and I have 4gb on my laptop I discovered Power Director requirements are 4gb, so I purchased yesterday.

Now, I'm finding today, when I go to edit a video, on the 3rd clip, the audio and video get out of sync and it doesn't take them long to get far out of sync.

I'm thinking it might be my computer. However, I've been editing videos on this laptop for many, many, many years, using Photoshop Elements and there were never any problems. In fact, when I purchased this laptop 4-5 years ago, the intent was to use for video editing so the specs at that time where in line with what I was doing (if my memory is right). In fact, this problem just started happening in December.|

I'm recording on my android phone usng an app called Open Camera, which is great becuase there are lots of custom settings. After research, I was thinking that my phone is recording at a variable frame rate, and my last software needed a constant frame rate. So, I encoded each clip (very time consuming) in "handbrake" at a constant 30fps but that didn't help on Elements.

So, after starting up Power Editor I thought I'd try the orginal clips, but still the same problem. However, when I try to upload the handbrake encoded files into Power Editor, the software doesn't see any files at all. Handbrake, it seems, saves file as .m4v files and not mp4. It seems Power Editor must not recognize that format.

Now, I don't know what to do.

Here are my specs:

hp laptop
Windows 10
4 gigs ram
Intel 1.6 ghz processor

videos recorded at 1080x720p HD

I don't know any other specs such as graphics card and don't know where to find the specs on those. I have my dxdiag. file which is quite long.

I'd appreciate any help.

HandBrake will use the extension m4v under some situations, like pass-through audio (AC3), use subtitles, have chapter markers enabled are a few examples. You can change in pref.

You can simply change the file extension between .mp4 and .m4v so PD will see it as the file is exactly the same. There are no differences in the content or container itself.

PD will usually provide less sync issues with constant frame rate material.

You've definitely got a lower power computer. But it's hard to say without knowing exactly which processor you're running.

Also, you say you're recording video at 1080x720? That's an odd ratio. I don't think it's right.

Open one of the videos from your phone in the free download MediaInfo. In MediaInfo, set View to Text and then copy the text of the report that the program generates and paste it to this forum. With this detailed information we'll better be able to say what's up and what you can do about it.

Although it might also be helpful to know your processor. In Windows 10 or 11, you can find this by opening Windows Settings and going System, then selecting About.
