Hello, I have recently received a Galaxy S5 and have played around with the slow motion mode a bit, which allegedly records in 720p.. It does not look like 720p to me, but it also does not look like low resolution video scaled up. It has taken me a while to get an acceptable result. This is the best I have come up with so far: Code:
How about uploading an unprocessed sample? I really don't know what you're trying to do with your script. You're using FieldDeinterlace but isn't the video already progressive? Also you're downscaling to 640x360 and then using sr() to upscale? :confused:
The first clip is unprocessed, I just trimmed the original video and encoded it at a slightly higher bitrate than the original. I can upload an MSU lossless version of the clip if you would prefer. I used FieldDeinterlace because it seemed to soften the weird artifacts a little, even after a downscale and super-res. I am scaling down and then using sr() to super-resolution it up to 720p again, because I do not know any other way of removing the artifacts without making the video look like garbage.
Reel.Deel, it's certainly progressive, but there are combing artifacts visible. What makes this even weirder is that there are also vertical combing artifacts. I have absolutely no clue what the S5 is doing to produce such garbled pictures. A random guess is that it's internally downscaling from 1080p to 720p and does something very wrong along the way. Just for the sake of deciphering what's going on, could you take a static video in slow-motion mode and normal 720p/1080p videos of the same scene for reference?

Thanks Reel.Deel, I did not know that half speed 720 did not contain the weirdness, but then why would you record effectively 60fps in 720 when you can record 60fps in 1080.

I really haven't messed with this much but the artifacts kinda remind me of 'cross-conversion'. I'll try with (or maybe ) and see if does anything (I doubt it)...
