Render quality/size ration: Vegas vs Adobe

MiCas wrote on 9/22/2019, 7:56 PM

Hi everybody! I would like to begin with statement that I’m not a professional video guy, just doing this for my family. But I like quality. I like my Vegas Pro 15: it is fast and responsive.

Few days ago I needed to edit a movie on the go and I tried Adobe Premiere Rush for iPad. After I came back to my home I tried to render short fragment of the same footage I was just amazed how good is rendering from such limited app on iPad in compare to my Vegas. I tried so many settings, but no luck. With the same file size render results of Adobe is way better. Is there is a secrete here or Adobe is really so good?

Thanks!

@MiCas Actually when you look more closely into this I find looking at the brickwork isn't a true comparison. In places your (and mine) Vegas renders with comparable bitrate gives a better result than the Adobe render. Have a look at around 4 secs and the "One Way" and "Do Not Enter" signs on the right. I suppose its a difference in how the codecs decide to spread their available bitrate across the frame. With the image constantly on the move Vegas perhaps decided not to waste bits on the moving bricks but use it elsewhere. At least that's my theory but I'm always open to correction.

Is this what you were looking for?

VEGAS:
Format profile : Main@L4
Format settings : CABAC / 3 Ref Frames

ADOBE:
Format profile : High@L4.1
Format settings : CABAC / 2 Ref Frames

Yep... Looks like Vegas does care more about close object, but Adobe overall picture.

Thanks! I haven't tried ref frames before.

What I realized, is when I increase bitstream on Rush (PC based version) the quality is very close to Vegas (more attention to close objects). And variable bitstream on Vegas makes it better then on Rush. Looks like not everything as bad. Thanks everyone!

Yes! I was waiting for someone to make that suggestion, and I agree completely, since it is also my first impression that the Adobe version is less faithful to the original.

Once again, it points out the pitfalls of objectifying one's personal impressions to include others, without any other supporting evidence. I don't agree with the quoted statement immediately above. In support of my impression, here are relative difference heat maps of each render compared to the original (as processed). Less visible noise is better, nothing fancy.

However the Adobe version was rendered, it has more visible degradation, not less. Do the oversaturated reds give the impression of more detail in the bricks? Not the case.

The first frame is missing from the Adobe clip, as well.
