Graphics drivers effect VS render quality?

[trailryder42]

Do graphics card drivers effect the final render quality that VS8 puts out, no matter what container or codec used? I ask because I recently rolled back my Nvidia graphics drivers to the older 377.88 to see if I could get hardware acceleration to work in VS, but as far as I can tell, it doesn't. Guess I'll be switching back to the newest 477.88.

I'm not sure if the older drivers are contributing to the very poor quality renders I'm getting of some Gopro 1080p 60fps 30Kbs video. I've tried checking the "same as project settings" and "same as first clip" checkbox, rendering as mpeg4 AVC, XAVC S, AVC/H.264 and .mov.

AVI and WMV don't have a 1080 at 60fps option to try.

The quality I'm getting is not even worth uploading to Youtube for it to then be degraded even more.

I'm watching the rendered videos back in Windows Media Player. Does the player I'm using make a difference in the quality that I'm seeing of the rendered video?

I'm going to render out a few 1 minute clips using the various containers and codecs settings I've tried and try to upload those for you to check out. Along with posting the properties of each.

Hi

Yes uploading samples will help, but a sample of the original video file would be better.
We can then render to other formats to test quality.

Different media players may differ in playback for some video types, VLC Media Player seems to play most formats.

I would think it’s a playback issue with your pc rather than a render problem, just thinking out loud………

trailryder42 -- as I am pretty sure I have said in at least one of your other posts, and certainly elsewhere, I have a GoPro Hero 3, though IIRC yours is either a 3+ or 4... I am in a PAL country, and so use 50 fps but otherwise I consistently use 1920 x 1080 and 29 Mbps. I have all the acceleration boxes in X6, X7 and X8 ticked, though like others am not really sure that makes much difference to rendering times. I have ticked the 'Show message when inserting first video clip' box, so when I insert my Hero mp4 I get a message asking if I want the Project Properties to match those of the video. I OK that. I do my editing and when satisfied, I simply choose Share > Same As Project Properties (though I could equally choose Same As First Clip). The resulting video comes out in beautiful quality and a true equal to the original footage. I play it back usually via VLC on my 24 inch full HD monitor, but also on my 46" HDTV where again the quality remains excellent.

In other words, I am at a loss to know why you are getting poor quality from similar footage...

I don't know how much the drivers are the culprit of the "noise" I'm having on VS MP4's , but I don't have that on WMV's
I'm using Nvidia driver 4 years old 267.85

I looked at trying the WMV but there is no 1080 option, even in the custom settings.

I realize the clip I'm going to upload for review has a lot of detail, as in grass, trees, wooded area, and while riding a mountain bike. Surely there's some way to have near the same original quality after editing my clips for color, sharpness, length, title, content and all that stuff for play at home, forget uploading to YT.

They say if you put crap in, you get crap out. As far as I know/can tell, the original footage from the Gopro is pretty good but, I don't know, maybe I'm expecting too much out of VS.

But then, I'm far from knowing what the hell I'm doing. That's where I hope you folks can help.

Do you use "Show Message" and "Same As Project Properties" as I mentioned above?

[trailryder42]

Do you use "Show Message" and "Same As Project Properties" as I mentioned above?

Yes Ken. I had been editing 30fps video. With this 60fps clip I've been doing lately, I got the pop up message to change project properties when I inserted it in the timeline.

I just tried bumping the bit rate to the max of 65Mbps the program will allow for an mpeg-4. The detail in the test clip is much better. Over 500mb for a 1 minute clip tho. I just think its odd to have to render at twice the originals bit rate in order to keep any resemblance of the original. I guess maybe that's just going to have to be the trade off.

I know unless you're doing things with the speed of your clips like slo motion and such, shooting at 30fps should be plenty, but I've been experimenting with the Feiyu G4 3 axis gimbal with my Hero 4 for mountain biking and the video is so surprisingly stable, I can definitely see the difference between 30 and 60fps, especially during any panning.

Before, My attempts at stabilizing videos with Mercalli has been quite a trip. Seems like less is more with that program. The gimbal videos need no stabilization at all, right out of the camera.

I don't know how I'd upload a sample of the original clip edited for length, as any editing for length then has to be rendered out, then its not original any more. The only way I know to upload a clip for you to look at is putting it on Youtube or the like. Is there another way? Will YT let you edit an uploaded clip for length? If so, I could upload the original and edit it for length there.

I see the attachment option for the forum but I'm unsure what the max size or length allowed is. And as I said, I don't know how to cut a current clip I have for length and file size without rendering it out after the edit, making it not original any more. I suppose I could go shoot another clip, a specific time/length, to attach if you let me know what specs you'd like to see, but I would need to take it in the same outdoors setting that I took the current clip I'm having issues with.

Why not upload the original to a site such as GoogleDrive or OneDrive?

Why not upload the original to a site such as GoogleDrive or OneDrive?

Because the original is 12 minutes long and 2.4GB in size. I've seen in other posts that you guys want only a 1 minute snipit or so. Too big a file makes it hard for a lot of people to download and see. What about uploading the VS rendered 1 minute clips of the various settings I've tried? Will GoogleDrive accept them as is or will it do to them the same that YT does? Even so, them not being the original for you guys to play with doesn't help you.

I uploaded the same 1 minute file in formats .mov, Mpeg-4 AVC, AVC H.264, "Same as First Video", and an mp4 with 65Mbps bit rate. The 65Mbps came out only slightly larger bit rate than the others after YT got done with it.

It's strange. After uploading them, I downloaded them as mp4 to see what YT did to them and those files are only 720 29.975fps, not the 1080 59.94fps I uploaded.

The "same as first video clip" you see in the YT link is pretty much how VS was rendering the original in all the different rendering options in VS, until I tried it at 65fps.

Hi

Once you have set your project properties to match your video file you should render to those settings, changing the data rate is not gonna improve quality.
Use Same as Project Properties or Same as First Clip, ( assuming your clip is the first clip.

Upload to Google Drive or One Drive.
2 gb is a little large, just takes a little longer to download, it usually completes eventually?

You could always record a few minutes rather than 12, that would reduce the upload times.

Uploading rendered clips is of no use to us, we need the originals to test.
It will be interesting if we can produce better video

I will however download the samples just to see the bad effect? ----- Yes they are poor

What is the quality if you upload the originals to YT, no editing or conversions?

Upload times is not a problem for me. I was thinking about how difficult it would be for you guys to get.

I'll upload the original and post a link.

Thanks for looking.

Which is why the suggestion was to record a new 1 minute or less video file and upload that for our ease of downloading.
