Old subject: totally different on output photojpeg vs h264 (screens included)

(1/2) > >>

skysense:
Hi people, i know this is old and unanswered topic but, can someone please tell me why is there such a difference in exporting photojpeg vs h264. I use Premiere Pro CC, video is slightly color corrected. It is the same clip, after rendering nothing is touched, just exported in two different ways. I added two print screens below so you can see the difference. There is a very noticeable shift in contrast, even in sharpness i would say.

Photojpeg settings:
* Quality at 90, Max render and depth qualityH.264 settings:
* Profile-High
* Level-5.1
* VBR,2 pass
* Max render quality and depth
* Target Bitrate 70/ Max 101
- PHOTOJPEG
- H.264
 or
Folder

Any help/suggestion is much appreciated.

Here's a good enough definition of Codec borrowed from Wikipedia "A codec encodes a data stream or signal for transmission, storage or encryption, or decodes it for playback or editing. Codecs are used in videoconferencing, streaming media, and video editing applications." The key word being the encoding, which in all cases means taking a huge amount of data and making it as small as possible while maintaining best quality. The method used by the various codecs differs and  during the decoding stage the image differs from the original. The question is, which of the two looks closest to the original? Which has the fewest artifacts? And which file is the smallest?

Shooter:
 photojpeg = banding gradients.

Thomas Dutour:
The Photojpeg looks much better but as stated by Shooter I have experienced some banding gradients.
I know Photojpeg is the preferred codec at Videoblocks. I do not think other agencies state their preferences regarding codecs.
So I use photojpeg now except if I have banding.

I experienced the same as the OP. I could never get h.264 produce super crisp details. It was always murky and blocky (After Effects CS6 or Media Encoder) no matter what bit rate I used.

I finally gave up on PhotoJPG as well (used to love it - never had banding issues) and moved over to ProRes which delivers fantastic results.

Files are huge but the quality is top IMO.
