This is really annoying. Ive made a few attempts to submit a 4k video to VB using their uploader. Within the upload box, there's a message that says: "Warning - Navigating away from this popup will stop your uploads." Okay fair enough. But sometimes I check back in about 20 minutes or an hour and this upload box has disappeared. So I have to start the whole upload process again from scratch. Ridiculous.

Does anyone else experience the same issue? Maybe I'll use their FTP service instead.

Very good points though like I already mentioned, I generally shoot my time lapse sequences in Raw anyway. Ive heard a lot of good things about Da Vinci Resolve but haven't tried it as yet.

I have some time lapse videos that I want to submit for stock but I have a dilemma with the aspect ratio. I do my cropping of the Raw stills in Lightroom. And although I crop them as 16:9, it seems that Lightroom does not do a perfect 16:9 crop. Because after exporting, I find that the cropped images don't exactly meet the specifications for the HD and 4k aspect ratio standards. For example, an image sequence might be 4096 x 2303.89 instead of 4096 x 2304. Or alternatively 1920 x 1079.80 instead of 1920 x 1080. Or 3840 x 2159.89 instead of 3840 x 2160.

Of course one thing I could do is add a little bit of black to the bottom or sides of the image to produce the required pixel dimensions, allowing for a true 16:9 aspect ratio. Though one thing I notice about some stock sites like SS is that they don't like mattes or borders etc added to videos. So doing such will probably get my TL videos rejected. Would there be any solutions to this issue?

Edit: Actually, I'm wondering if this is something that is really worth worrying about at all. If I did add a bit of black to the clips to make them precisely 16:9, it would only be a few black pixels that encroach into the image area. The amount of black would be so tiny that I wonder if reviewers would even notice. Unless they have automatic systems that detect such things? I guess I may as well submit one anyway and see if it gets accepted or not.

It's been a while since Ive read Videoblock's technical requirements. I read them when I first signed up but have since forgotten some of the finer details. I read them again just now and was surprised to read that the minimum bitrate they accept is 50,000 kbps. That seems unusually high if you're submitting HD content. None of my HD cameras capture bitrates anywhere near that figure and I wouldn't exactly call them cheap cameras. They're definitely not point and shoots. Among them is a Panasonic G6 which has a fairly good reputation for HD video and produces a bitrate on average about  23,629 kbps or thereabouts. I have an older GoPro model that boasts a lower bitrate than that.

Thinking about this some more, I'm curious why they accepted a 1280 x 720 video from my Panasonic G2 since the bitrate for that clip would have been around 5,812 kbps.

The newer GoPros record at 45 or 60 mbps, but of course it can be set to lower bitrates to save space, which is probably why you saw the 15 mbps clips. I wouldn't use that unless I had to though.

I have an older GoPro Hero 3 Silver and as far as I know, the bitrate can't be changed. I don't really have any choice but to use those clips for stock as Ive got some nice footage from that camera. I won't colour grade those clips however.

Though there's an additional issue. It looks like my GoPro has some dust on the sensor - sometimes it shows up as a dark spot in the footage, depending on the background colour. For some scenes, I could 'hide' that dark spot by importing the background colour from Photoshop and filling it in. Unfortunately, with some scenes with busy, constantly changing backgrounds, it would be impossible to fix.

Some beautiful footage there. I especially liked the lone tree immersed in the water.

Increasinglydifficult, would AVCHD clips be okay to colour grade without too much damage? I would only be doing minimal grading with mine.

Thanks for the reply, Matt. By the way, when I'm uploading to Adobe Stock, I'm still experiencing those technical issues where some of my images will not make it through the portal. I'd say roughly half of the images I try and upload don't make it through. Trying multiple times and on different days doesn't seem to make a difference. It's hard to build up a decent sized portfolio on Adobe Stock when so many images cannot be submitted.

Thanks for the link! That did the trick.

I cannot upload photos at all at the moment. I keeping trying again and again and keep getting an error message. Extremely buggy.

Ah excellent. Thankyou for the info. I'll have to start familiarising myself with Premier Elements.

You need to find an option called "interpret footage" or something similar in your software.

I played around with the software for a bit but couldn't find what I was looking for. I wonder if other software programs make this kind of thing easier. I do have Adobe Premier Elements which I haven't used yet. And I'm considering downloading Open Shot and trying that as well.

All you're telling the computer to do is change the playback speed, just like with film. If you have filmed 50 frames per second, it will play back at half the original speed played back at 25 fps. Instant slow motion. 

Theoretically, yes. But the tricky thing for me is working out how to do this with software. Like I said, it's so much easier with film (at least for me.) Dead easy. Run that 54fps footage through a projector and it's instant slow motion!

Yea Ive contacted them just then. And yes, they don't have my payment details quite yet so I assumed they would simply put my payment on hold when I reached the threshold.
