Problems with video quality after rendering in Vegas Pro 13

danila-f wrote on 2/3/2019, 4:25 AM

Hi guys, need your help with the following:

I've got several video clips made with drone in 4k. What I've done before rendering:

- Adjust project setting according to source video ( http://prntscr.com/mfynao ). Source video has a following settings ( http://prntscr.com/mfyniu )

- Disable resample in properties

- And here are my rendering settings ( http://prntscr.com/mfynz6 ) and ( http://prntscr.com/mfyo1v )

After rendering I see some kind of pixels in the lower part of the video, it's seems like some parts of the video not that fast as the others.

Please find mentioned footage here: https://yadi.sk/i/F4Bq0POAZZGRkg

What would you recommend to change in settings to avoid such problems?

Thanks in advance for you help!

Thanks for the very good info.
Nothing wrong with your settings I think, but maybe it is better to switch off in your rendertemplate the CUDA option and do it only by CPU.
I saw in the past also that kind or artifarcs with CUDA .
You also have a good option with the Sony AVC encoder, with the same template settings.
That one I used in the past most when still working with Version 13.

Thanks for the reply! I've finally found out the problem. I've changed bitrate to 135k and problem disapeared

Hi, no problems with the links. It's a screen capture tool service Lightshot, they even have an article on Wiki ( https://ru.wikipedia.org/wiki/Lightshot )

No, your first link redirected to a persistent spam site.

Sorry you don't think this happened. I stand by my report.

Strange, I don’t have a problem with the first link... at least not on my phone.

I don't agree your findings. All the links are ok and it are all only pictures made by Lightshot.
This is my result of the first one

Maybe you have a problem on your own hardware.

The OP can upload images directly to the forum.

I will not argue.

That is the main issue and I am not sure why so many posters just can’t do it.

FWIW, the links for pictures on Lightshot open as they should for me. (currently using the PaleMoon browser). I use Lightshot frequently for grabbing screenshots, ect., but upload directly to forums when possible.

Back to the problem of the OP.
@danila-f That setting 0f 135K (135.000 bit) is far to low for 4K when it is as you wrote above.
That setting means this

and rendered with your provided file it gives this result

Your screenshot of the rendertemplate you were using was ok for a good result with max 40MB and average of 28MB.

I fixed some links in the above posts. The forum software incorrectly includes trailing punctuation such as brackets in automatically-created URLs, which often results in broken links.

Rather than posting images and videos on external sites, please post them directly to the forum using this button:

@NickHope

Hi Nick, is there a limit size wise, resolution wise, on videos that can be posted, uploaded using the upload link. I haven’t ever done so and am just curious in case I ever do need to, thanks.

@Former user I assume there are limits, but I don't know what they are. There's always YouTube if a video upload to the forum fails.

Got that nasty extension off Chrome PC, and am viewing on Android. 'Nuff said.

The problem is blocking and assuming it does not show in the source, is caused by low minimum bitrate during render.

In the encoder you chose, we raise MinBR indirectly by bringing the ABR closer to the MaxBR.

I suggest you set the bitrate halfway again to the Max, like 40, and retest. That would solidifying resorting to astronomical 135 Mbps, which specializes the problem, but would be completely unwatchable at this end.

I see exactly the same issue with Mainconcept/Magix AVC encoder since VP12 (some "blocks" moving on these red things on my video exactly as on OP's video). It was better in VP11. Reported twice (to Sony, then to Magix).

Sure, you can make the issue smaller using higher bitrate. Or another encoder (I chose this way).

I believe, the issue lies in internal encoder's parameters that reserve not enough bitrate for 'low frequency" information.

Aok.
