You have to group videos and catalog them in a certain way + you have to submit a demo video featuring the clips. They sent me an invite and I told them that if they auto generated the demo, accepted csv files and offered higher commission rates (I think any new site should offer commission rates greater then 55% getting into the game at this late stage) then maybe. But to ask for more of contributors and not deliver with royalties then why would anyone bother. But to be fair I will paste their email reply below as I was impressed with it and they may be a site to watch.
-------
First, you are not coming off as rude at all. We appreciate your honesty and candidness. I have take the time to answer your questions in order below�

1) Making a demo is a big ask for only 70% for 2 years.

We encourage 15-20 second demos of the packages to facilitate a better experience for our customers and generate more income for you. Since it�s a package, rather than individual clips, we�re selling the best way to easily showcase the package content is with a demo (trailer). We know that customers enjoy getting a brief summary of the package. Once the demo has generated their interest they will watch each clip and in the end buy the package. We know that production schedules can be grueling so we also have an Auto Demo Generating Service on the site to make the package creating process a little easier for our contributors.

2) 55% commission is low for a new stock company to offer especially when other new sites are offering 70% or 100% like Videoblocks (which in the last 3 months has added an additional 1million videos due to this high contributor royalty rate)

We feel that 55% is a fair percentage considering we are still in beta. Our funds are currently being allocated in to building the best platform possible and amassing a library. As it stands, nothing is set in stone and things may change in the future regarding royalty fees. Videoblocks has been around for way longer than us and sell individual clips. They also have paid subscriptions which help them pay at 100%.

3) $49 for 4K clips (in a batch of 6) is not adequate, the average range is between $299 and $89 per 4K clip, Videoblocks has been giving me $199 for a 4K sale.

We are not selling individual clips. This concept is what separates us from other agencies. We sell b-roll packages of 4-7 clips each. You can easily increase the amount of money you make per clip by simply decreasing the amount of clips in your 4K package. Maybe for 4K packages you can have 4 clips in each to increase the amount to $74 per clip. Keep in mind that our prices are at a promotional stage right now to encourage customers to buy.


We are eager to engage contributors like you to set a high level of produced footage in our b-roll library and give our customers an idea of the quality and diverse footage they can get. We are looking for video experts who can deliver multiple video clips on particular subjects such as aerials, time lapses, or specific locations, countries or activities and it is obvious that you are an expert in many topics. We would love it if you became part of the B-RollStock.com team!

We understand that at this point it may seem that our rates aren�t reasonable, but they are for the time and stage we are in. We comprehend where you�re coming from. We are filmmakers ourselves and are completely empathetic to the production struggle. It�s hard work and we love it. Know that we are not in this business to take advantage of anyone. We have a mission to corner the market with a great idea that production houses will gravitate to as soon as they realize that we have �every angle covered�.

I gave up uploading to 123rf as I could not the the csv to work. I wrote to them 5 times to check what the issue was and finally got this random very unhelpful reply.
"We've checked your CSV and notice that your Oldfilename did not match your Orifilename.
Kindly check your both filename and try to upload your CSV again."

Hi,
I understand that Fotolia does not accept CSV or XML files but are now accepting meta data embedding in video files.
Does any one have any tips on batch editing files on Fotolia, I uploaded a heap of videos before I realised that I could not batch edit them using a csv and I really don't want to have to delete them, re-edit the meta data for each individual video and re-upload them.

Anyone come up with a workaround? Is there a workaround to batch apply meta info? 

I started in stock shooting macro insect footage (as it was a hobby different to my commercial video work) and had some direct sales with Natgeo + a few funded docos.
I then decided to upload the clips to Pond5 (about 300+ nature macros) and really only had a few sales (none in the last 3 years) I think I may have lost a sale to Natgeo after pointing them to the site apon request as they may have felt that anyone could use it instead of selling it directly as I had done.
Nature footage is best sold on YouTube, a short sequence with some nice music + a view count brought in the sales from requests to use footage.
Hard to shoot nature is worth more then what you get from iS or SS.

When I buy stock video I will go for the prores or .h264 however I only upload .mov due to this 'misconseption'.
From my own tests on the photo jpeg mov I find that you get greater artifact's with gradients. For example if you shoot a landscape at 12pm (not that you should) with a cloudless blue sky, I found that the mov had terrible square block artifact's when the mp4 edited export did not. Even when rate is at 95%. As for it being more 'grade' friendly well personally
you buy clips that fit your edit colour wise and grade over the top. You are a fool to think you could bring back a highlight or brighten a shadow in either the mp4 or mov.
