Hey, say you have a free account and videos that are HD, uploaded from when you had a Pro account.

If that user were to upgrade to Pro, would those videos they have that are HD be re-processed into HD automagically, or would they have to put in a request to have them re-processed, or are they SOL?

"Only Pro accounts have HD playback."

Is this correct?

a) Anyone can shoot and upload HD video.
b) A pro account HD video will be able to be played back in HD by both free and pro accounts.
c) A free account HD video will not show the HD quality option to anyone, either pro or free.
d) If the free account is upgraded to pro, all the HD videos will immediately have the HD quality option available.

Dan (aka firrs) says:

Wow - a welcome addition, but what are the details?

720p means widescreen (16:9)? ...so 720 pixels vertical and 1280 pixels horizontal

...or can we have other aspect ratios as with the regular video so far.

What is the frame rate? 24p, 25p, 30p?

Edit: And are the pixels square?
Posted 100 months ago. ( permalink )

Flickr Staff

Zack Sheppard PRO says:

Just like with standard video you can use whatever aspect ratio you save it as. As long as it has 720 lines of horizontal resolution it will have the HD option on pro accounts.

For frame rate, if the original video is 29.97 fps or more, it will show as 30 fps. If it is less than that we will show it at the original frame rate.

Pixel shape is square.

[edited to correct the frame rate and add pixel shape]

But one thing is to maintain the 90 sec limit - but with the introduction of HD shouldn't the 150MB limit be raised? So you can upload 90 sec of HD video?

Is this for real? A 10Mb limit on HD videos for pro users? How can you possibly get anything under 10Mb for a HD video? I have one video which is just 14 seconds long and even that is 15Mb in size.

I am also confused whether the restrictions are on the file size or video playback length - or both?

I am glad Flickr has gone HD with the videos. Now, I would
like to see the caps removed. NO, not for free but another
level of paid membership, say PRO HD? PRO Plus? Ultimate
Pro? Anyway, as more and more camera/video camera are
shooting HD, I would like to upload these and share them
but it is now capped at 150mb and/or 90 sec. That is a
10sec clip on 5D Mark II. I would love to PAY for the next
level of membership which offers the video services like
Vimeo and/or Smugmug. I hope the service will come out
soon. Thank you and please let us know if you have
anything in the works. Oh, $49.99-$69.99 per year would be
nice.

striatic PRO says:

a couple bugs:

1] if you go to www.flickr.com/photos/striatic/3326320677/ with HD off, there's a 1px black line imposed on the right frame of the video when it starts playing. this is quite noticeable when the video fades to white. i saw this in both Safari 4 and FF 3 on OS X.

you can see that the right border is not part of the video itself [probably part of the flash wrapper] by switching to HD where it isn't visible.

2] the HD button is available on the main photostream view if you've set up the main page to show 5 "photo page sized" images... but the button doesn't do anything, which is confusing.

and a suggestion:

please, please, please try to adapt for browsers supporting the <video> element in the future, such as Firefox 3.1 - provided their final implementation doesn't totally suck.

please? because relying on flash is really, really, really annoying and i'm sure the greasemonkey hackers would have a blast with the video element + js controls.

striatic PRO says:

720x480 is not HD. 1280x720 is.

the answers to your questions are all in the flickr video FAQ:

www.flickr.com/help/video/

What is HD?

HD refers to High-definition video which has more lines of resolution and generally looks more beauteous than standard video. HD video on Flickr is 720p (just like HDTV) which means that there are 720 horizontal lines of resolution in the video.

Here's a list of the file formats we accept:

* AVI (Proprietary codecs may not work)
* WMV
* MOV (AVID or other proprietary codecs may not work)
* MPEG (1, 2, and 4)
* 3gp

mattvandyk says:

@striatic: The problem with 1280x720p h.264 is that even though it's MPEG4, the file size on a 1:30 clip is way over 150MB. My camcorder (Canon HF10) shoots in AVCHD at 1920x1080i at 17Mbps. This is an extremely common set of settings across multiple brands. Obviously, the native .mts files are too big. So, in an effort to get it down to 720p with as little quality impact as possible, I'm using Premiere Elements 7 to take the 1920x1080i/17Mbps source material and render it using h.264, 1280x720p, square pixels, 1-pass VBR with 17Mbps as the target bitrate, etc. Even for content with relatively little action, the result of a 1:28 clip is about 250MB.

This is a long-winded way of saying that either (a) something needs to be done about the file size, or (b) someone at Flickr should post the suggested settings (i.e. resolution, p/i, pixel shape, bitrates, framerates, etc.) to maximize quality along with the maximum specs in those departments of the HD player so we can take that info and make those decisions for ourselves.

As it is, though, while neat in concept, in practice, the ability to display and view 720p content while still having a 150MB cap on 1:30 clips doesn't make a lot of sense.

PLZ double the 150mb the cap and loose the time cap - what´s the difference if a 150mb file plays 90sec or 10 min.?

mattvandyk says:

@Dan (aka firrs): That may be, but 88 seconds using VBR with 17Mbps as the target bitrate is well over that for a clip with very little motion, so I'm somewhat doubtful that dropping it to 13Mbps CBR is going to fit within the 150Mb cap, but I'll give it a go and post the result.
Posted 100 months ago. ( permalink )

Dan (aka firrs) says:

mattvandyk There are 8 bits in a byte so 13 million bits per second is 1.625 million bytes per second (13/8). Over 90 seconds that's just under 150 million bytes (90 x 1.625).

Constant bit rate of 17Mbps will be 190 Mb for 90 seconds ...and variable bit rate could well be higher.

We don't know what bit rate flickr compresses to for streaming but it will be a lot less than those to better fit with typical internet connection speeds.

Dunstan PRO says:

If it helps, when saving out my files from Final Cut Pro I've found a fixed Data Rate of something like 6500kbits/sec almost always brings my clips in under the 150mb limit (and usually wayyy under the limit, like around 60MB for a 1min clip).

And I'm saving out at 1920x1080.

My settings are normally:

Compression Type: H.264
Frame Rate: current
Key Frames: every 24 frames
Data Rate: 6500kbits/sec
Dimensions: 1920x1080
Sound Format: AAC
Sound Bit Rate: 128kbps

Hope that helps.

mattvandyk says:

@Dan: I understand the math. Of course, it's not quite that simple since varying compression schemes, varying resolutions, varying framerates, and variations between interlaced and progressive all factor into how big the file actually is. The proof of that is in the proverbial pudding. In my example, I have an 88 second clip that is about 250Mb (about 60Mb higher than your projection) even though it's shorter than 90 seconds and even though it uses VBR on a low-motion scene (and, as a result, almost certainly has an average bitrate significantly lower than 17Mbps CBR).

This is all beside the point, though. I stand by my position that either (a) something needs to be done about the file size cap, or (b) someone at Flickr should post the suggested settings (i.e. resolution, p/i, pixel shape, bitrates, framerates, etc.) to maximize quality along with the maximum specs in those departments of the HD player so we can take that info and make those decisions for ourselves.

@Dunstan: the key variable is the bitrate. Given that the player Flickr is using to display these certainly caps a lot of this, in your experience, is there an appreciable difference in terms of the quality of the video viewed on the site "in HD" between "6500kbits/sec" and, say, "14400kbits/sec" (which I think is the max Premiere Elements will do for a h.264 .mov)?

Thanks!

Why not try it both ways yourself?

mattvandyk when Premier tries to meet the VBR target it has to guess. The actual average bit rate for your video must be higher. If there is no audio it must, by definition, be 22.7Mbps.

I doubt VBR has much advantage for short videos. I recommend you use CBR as it will be more predictable in terms of the final file size.

@Colleen: Because I spent weeks trying to squeeze as much in terms of PQ out of the limits of the pre-HD Flickr Video setup last time by trying just about every conceivable variation, and frankly, I'm disinclined to go through that headache again -- particularly when staff likely tested this already and have the "best choice" in front of them. No, it's not rocket science, but it it time consuming to sit there and render, upload, test, re-render, re-upload, re-test...particularly where, as here, the source material is AVCHD (which is notorious for being somewhat demanding of resources in editing) and the files are big enough to actually require some significant waiting for an upload.

@Dan: No, it's definitely not 22.7 or anywhere close to that. The cap at the high end is well below that even. I'll throw it in my PS3 and tell you what it is when I get home, but the average bitrate is almost certainly closer to 10 than 22. Regardless, I'll try CBR @ 12 and see what happens.

@striatic: The problem with 1280x720p h.264 is that even though it's MPEG4, the file size on a 1:30 clip is way over 150MB

as has been suggested, just change the bitrate. adjust the bitrate so that the total file size is 150mb.

when you process a 1280x720p h.264 mpeg4, cap the output file size at 150mb and let your compressor do the math. or if the program you're using to compress won't do that, you can do the math yourself and set the bitrate manually.

flickr renders HD videos with the following properties, if you want to match the lowest common denominator settings:

1280 x 720p, Stereo, 44.100 kHz, 29.97 fps and at a bitrate around 1000kbps

you can use this as a guideline for the minimum settings, but when you say someone at Flickr should post the suggested settings (i.e. resolution, p/i, pixel shape, bitrates, framerates, etc.) i thoroughly disagree with you because all these settings are subject to change and re-render from the original. in order to future proof your videos as much as possible, retain as many of the original capture settings as you can, and adjust only the bitrate to get yourself just under whatever flickr's current limit is.

I just posted another video and noticed what the issue is about it stopping in the middle while the music continues. Its not stopping, its done! Flickr is speeding up my videos. Example:
[https://www.flickr.com/photos/cazimiro/3331308233/]

This video is 1:06, it finishes in about 30sec! i played it side by side with the original on my desktop, the flickr video was at double the speed, wth?

I created the video using quicktime, put all 999 at frame rate of 15fps to give me the flow i like, saved it as an mp4 and uploaded it. why is it increasing the FPS???

Cazimiro says:

Disregard. I figured the issue out... when opening the sequence in quicktime, one should pick whatever frame rate gives them the desired effect.. on export though, go up to 30 or 29fps, not "Current"... that equaled it all out.

Originally HDTV was 1920x1080 at various frame rates. The manufacturers wanted to sell this new technology, but producing hardware that would fully support that resolution was too expensive, so they came up with the silly 1280x720 thing. And to make sure no one would notice they just called it HD as well.
Now they can make TV at reasonable prices in what HD was always supposed to be: 1920x1080 and they are marketed as "full 1080p" or "full HD". 720p was always just an intermediate step, a cheat to push HD.

But the cheating goes on much further. 1920x1080 is only the theoretical dimension. What happens in reality is that pretty much any camera but even more so TV stations use heavy, and I really mean heavy, compression to reduce the ridiculous data that is required for that kind of resolution. "Compression" is a nice way to say, trashing data.

1920 times 1080 times 24 frames per second times 24 bit color depth is way way more data than any internet connection can handle, it is more than most HDs can handle. That's why they compress the hell out of it.

Part of the compression is to reduce detail a lot, so the theoretical resolution is pretty much never reached. I have uploaded a few videos here. They got compressed so much that they are not anywhere near the resolution they could be theoretically.

It's funny when people think, oh let's go HD so we get better video on flickr. It's pointless to increase the theoretical resolution if the standard video is compressed so much that we are not even close to use it's maximum.

What´s the use of the time cap? i have a HD Video of 39mb with a length of 3:05 min.

Dan (aka firrs) says:

The time cap is 90 seconds. I've never tried, but I think if you upload a longer video it'll work but you'll only get the first 90 seconds.

I'm not sure about the scaling of the player. I've just uploaded a 720x720 video and it's too tall on the photopage to be practical.

the time cap isn't meant to relieve stress on flickr's servers, so much as it is meant to influence the nature of the uploaded videos.

"

Sorry, but I just disagree with that assessment. I would rather have software I know, trust, and understand handle the scaling, deinterlacing, bitrate, framerate, etc. issues than have the Flickr software take care of it, since it's going to have to be monkeyed with between the source content and the Flickr player at some point along the path anyway. I agree with you that, where possible, you should leave the settings identical to the source material (although, unless your software can selectively smart render, that's not likely to be relevant); but, to say I should take my 1920x1080i/17Mbps source content and upload it at 1920x1080i at a bitrate that fits under the cap rather than at 1280x720p at an inevitably higher bitrate that fits under the cap doesn't make a lot of sense. First off, I'd rather have control over the scaling myself so Flickr doesn't have to do it again; same thing goes for the deinterlacing; most importantly, however, once I drop down the bitrate low enough to accommodate 1920x1080i at a file size under the cap, there's no real way for Flickr to increase it (without quality loss) when it scales and deinterlaces the material to get it back up to the max that will fit under the cap at 720p.

So, since there will inevitably need to be changes to just about everything (save probably framerate) between the source material and the Flickr player, I'd just like a Flickr staff member to tell us what the ideal settings are in this department for the best quality playback in the Flickr player.

What settings are people using for upload?

My videos are not showing as HD.

I uploaded them at 500/281 to save space and it appears flickr does not recognize they are from HD source material.

With a pro account, saving space is a non-issue! You have unlimited storage and unlimited upload bandwidth.

@tradewinds: Prior to the addition of the HD feature, I did something similar to prevent resizing by Flickr. Now that it's 720p, I'm still working on what settings give me the best results (and am looking to Flickr staff for some help in that regard), but for the time being, I'm using MPEG-2, 1280x720p, 12Mbps, Square Pixels. The quality is passable, but not great. Strangely, I'm having better luck with that, though, than I was having with QT/MOV MPEG4/H.264, which, technically, should be higher quality in less space (enabling a higher bitrate to be used).

FYI, here's Vimeo's suggestions regarding export settings for video uploaded to their site: vimeo.com/help/compression

Although, presumably, Flickr uses a different embedded player, I'll give these a try this evening.
