Auto-normalize and volume display between versions / export speeds

Lancelot_Chan

same project, shown in 11.73 is like this

Shown in 12.07 is lower volume displayed (but they do play about the same)

http://www.rsw.com.hk/1207.jpg

Then I used OBS studio to record the playback volume between the two versions. There are some differences, though not as significant as before:

The left one is 11.73, which is louder. The right one is 12.07, which is quieter.

Also, I still can't get 16 threads processing for h264 videos in 12.07 with x264enc7.exe

But since NCH Software kindly let me continue my registration for 6 months with 12.07, I'll kindly keep testing the updating versions for you. 🙂

Plus, the noise removal works now.

Using 12.07, here's a file with low audio where 'normalize external' has been disabled...

With it enabled...

Same file, which is ALREADY at optimal level. With 'normalize external' disabled...

With it enabled...

NCH is still optimizing this function, but it looks to be working well in this release.

Can't comment on x265enc7.exe, as it's not seen here. Compare rendering speed results.

Lancelot_Chan

Rendering speed results are big difference. Otherwise I won't keep nagging on it. LOL.

Specifically, what does 'rendering' refer to? If 'export' - testing a 2:15, four-track project (3 MOVs and 1 blank clip)...

1080, 45fps, h264 with the default GPU setting...

Version 11.73 (64), Version 12.07 (32), Version 12.07 (64) - all the same at :42.

Lancelot_Chan

Yes, export speed is huge difference between 11.32's 16 threads running x264enc7.exe and the later version that run it single thread only.

I took the time to make a video for you to demonstrate the huge difference.

Upload the same project for analysis. As above, a short test showed no difference between 11.73 and 12.07.

Under OPTIONS | EDITING, at the bottom, select the GPU instead of Default.

Please list your PC's specs: GPU/CPU.

I'm using GPU already. Radeon R9 370. CPU I7 990x

Thanks for sharing.

The project appears to be somewhat different than your example - the bulk was blank, but for the logo at bottom-right, yet that shouldn't impact the test here.

At your 2800kbps export quality, GPU activity was high, using 64-bit VP releases....

Version 11.73 2:04

Version 12.07 2:02 1:10 @ 29.97fps

Have you tried the R9 370 GPU setting option?

Lancelot_Chan

Yes, I was using R9 370 GPU all along and almost no gpu activity at all during export, for both 11.32 ver that I use mainly for h264 export since it uses 16 threads, and 11.45 ver that I used for H265 export. Just wish the programmers can take a look in the issue.

borate

An AMD thing?? File a bug report, and refer to this thread... https://www.nch.com.au/software/bug.html?software=VideoPad

Lancelot_Chan

Done!

borate

Passed along. Try the default setting as well.

Lancelot_Chan

Tried, same result with the 11.32 and 11.45. So the GPU wasn't involved in the export. I noticed the GPU does have activity at editing mode. But once I press export and cleared the editor, GPU activity died down to idle, or almost idle.

Export time with 16 threads X264enc7 running, with CPU only setting, is 1:24.79, without the OBS recording running.

So it shows that there's absolutely no GPU involvement in the export. I didn't bother to try the single thread h264 export for it takes 2x time.

CPU on the left, GPU at the right. v12.07 - 64

Lancelot_Chan

is this an encoding process, or playback process in the editor?

I envy your system working like that either way.

borate

Nothing much during playback.

Seeing some GPU action when re-encoding during editing and considerably higher numbers when exporting..

Lancelot_Chan

Very good, that's so ideal!

as you may read here, not only I have experienced that single thread slow exporting issue. They just don't come to here to raise the issue. So I think I'm definitely onto something NCH should work on.

borate

Will any program run precisely the same on every PC? Not likely. Hardware may be the crux, considering its infinite permutations.

64-bit 12.07 export here on an I7 with a GTX1060 card. 12 active processors, default h264 settings,

I made a compare of using the h264_amf hardware encoder on shotcut vs the export of videopad, doing the same video. Speed is like double when using GPU hardware encoder.

yeah I know my computer is old. Just envy you. 🙂
