Problem Downsizing Videos

Russ_Croucher

I'm experiencing problems downsizing a 4K video to HD(1920x1080). The original source file was an Apple MOV. I was able to convert it to a 4K MP4 with video pad perfectly. My goal was to go to HD but was experiencing some problems. So I took a 1 minute segment of this 4K video and created a 1 minute 4K video in MP4. This has become my source file that I used to create a 1 minute segment in HD with video pad and a 1 minute segment in HD with handbrake. The handbrake produces the file perfectly but video pad seems to have some flickering going on. I'm just asking for help. Here is a link to the 3 files which is the source 1 minute 4K file and the 2 output files 1 handbrake and 1 video pad.

I downloaded the latest version today 11.08.

Clean here at 1080, using version 10.96 or 11.08 (both 64-bit). Also solid with the H265 encoder.

You take my video pad HD version and it's solid on your end untouched by video pad? So it's something with my computer?

Should I uninstall and reinstall it? Maybe something happened to my computer? It seems to be rocksolid as long as I don't change the resolution size.

borate

Yes. the tests were made with your original, not the VP or HB exports. Things to try...

Install version 10.96.

Verify that the video driver and Direct-X are up to date... https://www.nch.com.au/kb/10265.html

If still bad, close the program and use Windows Explorer (file manager) to delete all files in these folders...

"C:\Users\<PC Name\AppData\Roaming\NCH Software\Components"

"C:\Program Files (x86)\NCH Software\Components"

Reinstall Videopad 10.96.

If I completely uninstall it and reinstall it will I still have my license? I'm on the quarterly payment system.

Would certainly think so - you're paid up. If there's a problem, the company would certainly rectify it.

But you need not uninstall prior to deleting the files, if necessary. Just close the program, then reinstall.

Should you have time on your hands, here's a beta build, which may have undiscovered quirks + several maintenance fixes.

Actually what I'm going to do is go back to an old version. Every couple weeks I back my entire system up with Acronis and I can go back to any version I want the last several years. So I'll go back a few months and see if the problem goes away. I know I have to update the version software to 11.08 but that's a normal thing.

borate

There's no mandate to update, and it's often wise to wait for a few weeks, to see if quirks surface.

Older versions can be installed, and the license will likely be intact; no need to restore an Acronis image.

Your file exports correctly to 1080 when re-encoded using 10.96, 11.08 and the beta release here.

Okay I tried my problem on my other computers and have the results updated on the cloud link above. They are perfectly rocksolid both Windows 7 and Windows 10. So apparently my personal computer workstation has caught some that causes a problem or I have installed something that causes a problem. So it's not video pad it's some other application I have installed apparently that causes that slight jitter. I will look into it.

That's a real advantage that I have been both being a software engineer and having lots of workstations with different Windows.

One comment I would like to know from you guys is why Windows 10 produces a MP4 twice the size of Windows 7 when all the configuration information is exactly the same (default file size, same FPS, etc. etc.). That really seems like I should make my MP4's with Windows 7. Is Windows 11 the same? This would action be a great example above to test the size. Since it creates exactly a 1 minute video of 4K.

No W7 here. But W10 and 11 produced a 257MB 4K file from your 4K original when using the LOSSLESS button on the toolbar.

Russ_Croucher

You cannot use lossless you must use the re-encode from 4K down to HD(1920x1080). When I run W7 in lossless mode it comes up with the same file sizes everything else 259K. It's when you do the re-encode Windows 7 down to HD only comes up with 49K and Windows 10 comes up with 110K. I'm curious to see what Windows 11 comes in as.

borate

A 1080 re-encode in W11 at default settings produces a 108MB file. Be sure to use the same VP version for the W7/W10 comparisons.

Russ_Croucher

I use v10.96 in default file size both Windows 7 and Windows 10. Apparently the Windows 11 has the same file size as Windows 10. Which is roughly twice the size as Windows 7. I would love to know why.

borate

A few more 1080 W11 export tests resulted in 153MB using H265 and 72MB for the MPEG4 compressor.

Russ_Croucher

I updated the link below to include the 1 minute segments from Windows 7 and Windows 10 using different encoders. Apparently I don't have a problem with size with Windows 10 because I redid it and it comes in and 50m. Notice how small the H265 size is WOW!

Yes, H265 produces a small, high-quality file, though export can be slow. All tests were clean; no flickering.
